Buggy & Wagon

_  If they sat in non distracted quietness during the recent pandemic, some people might have had time to reflect upon the simpler necessities in life.   For example in February 2021, seven million Texans had to endure usually cold weather for a period, without electricity to illuminate or to warm their homes.   They had to boil contaminated tap water before they could drink it.  Suddenly inconveniences like the unavailability of toilet paper shrunk in importance, compared to simple survival during the dark and bitterly cold nights.  A sobering and unpleasant reality check for some no doubt.  Elsewhere, society has been in ‘isolation mode’ so to speak.   At no time during this pandemic however, has our freedom of mobility, been threatened.  Those that can, jump into a car or onto a motorcycle to get outside and to escape the isolation and entrapment of their domiciles.  For a century now the automobile has been a symbol of independence and personal freedom.

  What if that freedom of mobility were lost or taken away?  What if our cars did not work?  What if some apocryphal meteorite strike or serious volcanic event changed the status quo?  What if China belligerently attacked Taiwan, causing the US to step in; and then multiple preemptive electromagnetic pulse (EMP) weapon strikes from outer space orbits, ensued?  Even if not a drop of blood was spilled, if such EMP weapons work as predicted then the electrical grid could be fried and unserviceable for years.  Only certain shielded military vehicles or antique (50 yr+) automobiles or farm tractors would be capable of moment afterwards.  Two hundred million abandoned and rusting “modern” automobiles would have to be bulldozed off the highways later, assuming the economy ever recovered.

  There are 4.09 million miles of navigable roadways across America’s fifty states alone.  Millions of people live and commute from many miles beyond the suburbs or boundaries of metropolitan areas.  Without the convenience of modern automotive transport, their lives would change drastically.  Some people have bicycles.  But you can’t pack much freight or haul many groceries home, while pedaling a bicycle.  After a suppositional crisis, some innovative people might try to bridle and use the nearest horse or other beast of burden, as their ancestors once did.  In most cases innovative and capable young people would need to relearn or completely re-invent ways to bridle, saddle or harness those work animals. Without the pressing stimulus of a calamity however, there should at least be some historical impetus by a few anyway, to maintain a knowledge and familiarity with pre-existing transportation technology.  There was more sophistication there than meets the eye.

Reinventing the Wheel

_ It’s easy for someone to gratuitously boast about today’s new extraordinary technology.  They might brag that contemporary technology has explosively expanded in just the recent decades.  Modern advancements in medicine, electronics and atomic theory are undeniable, yet these and other achievements implicitly rely upon a multiplicity if ideas and of hard won knowledge, earned by preceding generations.

_ Consider transportation for a moment.  Compare then the marvel of mechanical engineering exemplified as the modern automobile, to the lowly horse drawn buggy which it replaced a century ago.  A car leans upon a long host of ancillary technologies before it can even begin to preform its own function. Temporarily ignore a car’s electronics & battery chemistry; its internal combustion engine with steel crankshaft, cylinders, pistons and then its petroleum refinement requirements.  Let us ponder instead some more primal but critically necessary innovations that the modern automobile inherits from yesteryear’s buggy or wagon.

 

  The wheel is probably the most essential mechanical invention of all time. The wheel is indispensable to some modern machinery (like Swiss watches or for space satellites using CMG gyroscopes), but let us just concentrate upon mechanical wheels for transportation.  Long before the invention of the automobile, the wheel had undergone much development.  Some of the wooden wheels found on the light horse drawn carriages perfected only a short century ago are in themselves, marvels of engineering.

  The oldest wheel found by any archaeologist so far, was discovered in Slovenia and estimated to be about 5,120 years old.  Approximately five thousand years would pass before the first internal combustion engine powered automobile would haul people down a road.  The Benz Patent Motorwagen built in 1885, used three wheels.  So chariots and carriages have been using wheels for at least 51.2 centuries, whereas automobiles so far have only utilized wheels for a meager 1.3 centuries.  A fifty century difference.

  

  The reader should not dismiss wooden wagon and buggy wheels as being simple and dismissable devices.  Those wooden wheels are the culmination of centuries of refinement; and it still requires quality materials and a skilled  wheelwright to fabricate a good one.  For example the chariots like the one Ramesses II used to scoot around the battlefield with in the 14th century BC, used spoked wheels; which were a great improvement upon what existed before.  Yet those early chariots had to come to almost a complete stop before they could be gently turned around.  Egyptian chariots could not be turned at speed because, the flexural stresses exerted by the mass of the chariot and contents turning too quickly, would shatter those wheels. 

Labourers are shoeing a wheel using hammers and “devil’s claws” to fit a hot metal hoop onto the felloe.

   An eon later the Romans (borrowing technology yet again from the Celts) would construct far superior chariot wheels by mounting hot, wrought iron tires.   While iron tires were initially intended to protect the wheel’s surface from road wear, the process of fitting ‘tyres’ tightly so that they would stay on and stay put, also deformed and substantially strengthened the wheel.  As the iron hoop cooled – it constricted, binding the components into a stronger cohesive unit.  Effectively the constriction if done right, pulls or presses the felloes, spokes and hub very tightly together, but in so doing usually causes the wheel to assume a dish or concave shape.  The compressive, flexural and even tensile strength of such a wheel are then dramatically improved.  Most wooden spoked wagon or carriage wheels made to this day, will sport similar concave or dish shaped profiles for this reason.  Strength.

Examine the similar disk shaped concavity of the wheels. The apparent “toe-in” of the wheels is a result of axle design – that brings each spoke perpendicular to the road as it begins to bear weight.

  There were other important innovations which automobiles inherited from coaches and wagons.  Rubber tires, spring suspension and luxurious padded upholstery were all invented for carriages and coaches; long before working automobiles were ever imagined.  Ornate coachwork, traffic horns, illuminating carriage lamps, and convertible or landau tops; are all embellishments that modern automobiles would inherit, not primarily inspire.  Even the paved, hard-packed road surfaces that today’s automobiles urgently require in order to function, were previously inspired by generations of wheeled, horse drawn coaches.

Rubber Tyres

  Surprisingly, pneumatic tires using rubber were created and used before solid rubber tires were.  The whole history of rubber seems a bit convoluted and unclear though.  About 3,000 years ago the “Olmecs” of  pre-Columbian Mezoamerica were playing a ballgame using an elastic rubber ball made of boiled tree sap.  A different tree sap from the “India rubber tree” (Ficus elastica) from Southeast Asia, was once used as a  lesser source of rubber by the Chinese.  Then there is the once famous “Gutta-percha” tree from Malaysia who’s latex can produce either an elastic rubber-like polymer or a hard natural thermoplastic.  Christopher Columbus might have been the first European to bring news or samples of the latex called caucho or caoutchouc (natural or Amazonian rubber) back from the Americas.

  The western world had known of the existence of natural rubber for a couple centuries before they started importing the curious tree sap in any quantity.  It was a gum, it was a glue, it stretched, it bounced back and it was waterproof.  Early in the 1800’s, multitudinous would be inventors were searching for commercial uses for the flexible novelty.  Some short lived rubber companies were formed; that made life preservers, rubber shoes, garter belts, doped water-proof tarps and clothing and so on.  A cotton fire hose lined with soft rubber was invented in 1821.  But these products were ultimately disappointingly unsuccessful because the physical characteristics of raw rubber changed with the climate.  In cold weather raw rubber became rock hard and brittle.  In hot temperatures raw rubber would turn into a gooey, sticky mess.

  After many trials and tribulations Charles Goodyear was the first to partially succeed in solving the conundrum of rubber; but it bankrupted him.  From 1831 to 1839 he was obsessed with rubber.  His mixtures of raw rubber with quicklime, magnesia powder and nitric acid, showed some promise.  The best solution though came by accident, when he dropped a blob of raw rubber mixed with sulfur onto a hot stove.  Goodyear and employer/partner Nathaniel Hayward share an 1839 patent for “vulcanized rubber”.  A few years later in 1844 Goodyear gained another patent – for the perfection of the vulcanizing process; by using mechanical mixing to replace the need for solvents.

  By the time Robert William Thomson patented the first pneumatic tire in 1845, Goodyear’s vulcanized rubber was already appreciated in Europe.  In his patent applications Thomson mentions using either sulfured caoutchouc or gutta-percha to rubberize a canvas belt, which would function as a tube or air bladder.  (Some collapsible canvas fire hoses are made the same way today – with a rubber lining on the inside).  The rubberized canvas – “elastic belt” was enclosed within a strong outer casing or sleeve of leather which was actually bolted to the wheel itself.  Thomson’s “tyres” or “Aerial Wheels” were demonstrated on coaches and carriages in 1847, and worked very well.  They were just too laborsome to make inexpensively and too novel an idea to catch on at the time.  Thomson’s invention might be called  “pneumatic leather tires” rather than rubber ones.  Forty years later John Boyd Dunlop would patent the first “pneumatic rubber tire” in 1888;  intended for bicycles – not automobiles.  Solid or “hard” rubber tires in the meantime were certainly an improvement over iron tires, and had already been in use for couple of decades before pneumatic tires appeared in number.

* G.F. Bauer registered a patent for the first wire tension wheel spoke, in 1802.  The first all metal tension wheel was patented in 1869 by Eugene Meyer.  The first patent for “rubberized wheels” was granted to Clément Ader in 1868.  The first “velocipedes” with wire wheels and hard rubber tires, generally began showing up after 1873.

  By the time the American “Rubber Tire Wheel Co.” was established in 1894, the English had already been importing mass manufactured wheels mounted with solid rubber tires; across the ocean, for several years.  But those tires were glued onto the wheels, and eventually slipped off.  Still, on brick or cobblestone roads; rubber tires absorbed vibrations much better than iron tires and made the carriages pull a little easier too.

The Rubber Tire Wheel Co. (soon to become Kelly-Springfield Tire) invented and patented a superior way to mount a hard rubber tire to a wooden wheel and make it stay.

Rubber tire companies <trivia>

– In 1869 Benjamin Goodrich bought the Hudson River Rubber Company and moved its assets to Akron, Ohio to form the BFGoodrich company in 1870.  Fist concentrating on improved fire hoses and rubberized belts for industry and agriculture, to eventually pneumatic bicycle and automobile tires by 1896.  The company was certainly helped by Henry Ford’s decision to source his first tires from them.

– In 1871 the “Continental-Caoutchouc– und Gutta-Percha Compagnie” was founded in Hanover, Germany; and would concentrate on the fabrication of soft rubber products, rubberized fabrics and solid tires for carriages and bicycles.  It would merge with other rubber companies and become known as “Continental Gummi-Werke AG”.  The company (now called Continental AG) would acquire General Tire in 1987 and become the 4th largest tire maker in the world today.

– Back in 1872, the tire maker known today as Pirelli, was founded in Milan, Italy.  Giovanni Pirelli initially specialized in rubber products such as insulated wire cables, solid tires and curiously scuba diving rebreathers.  Pioneering diving engineer Henry Fleuss would patent and fabricate a working “self-contained underwater breathing apparatus” (SCUBA) in 1878.  His apparatus required rubber for the face mask and breathing bag, and would use fabric soaked in potassium hydroxide (caustic potash) to act as a filter to scrub or separate the oxygen exhaled from a diver’s breath – and then re-circulate it.  In 1878!

– In 1889 the Michelin brothers of France, improved the pneumatic bicycle tire by designing one that wasn’t glued on, but could be easily removed (Dunlop’s invention was only a year old at the time).  The brothers had inherited a family company on the verge of insolvency, which had been making some vulcanized rubber products for farm equipment.  BFGoodrich and Uniroyal were absorbed by Michelin in 1990, and today it is the largest tire manufacturer in the world.

– In 1892 Uniroyal Inc. (United States Rubber Company before 1961) was formed by the merger of nine smaller rubber companies in, Naugatuck, Connecticut.  At first the company focused on rubber-soled shoes and canvas-top “sneakers”.  Years later a scientist employed by the company invented “Ameripol” (a cheaper version of synthetic rubber) that greatly assisted the allied war effort in WWII. Uniroyal was purchased by Michelin in 1990.

– In 1894 the Kelly-Springfield Tire Company (owners Edwin S. Kelly with Arthur W. Grant, both citizens of Springfield, Ohio) was launched as a firm initially named “The Rubber Tire Wheel Co.”.  The company was intimately associated with quality solid rubber tires for coaches and buggies, sold to an American market.  In fact Grant and Kelly patented a product that would stay on the wooden wagon wheel, when other tires eventually slipped off.  Their design included a metal U-shaped channel that was bolted to the wooden felloes of wheel.  Then strong wires running in channels inside the rubber tire, were drawn tightly and fixed to hold the rubber down. In 1899 The Rubber Tire Wheel Company was sold and renamed “Consolidated Rubber Tire Company”.  By 1914 the company was also making pneumatic tires and was again renamed to “Kelly-Springfeld Tire Company”.  Kelly-Springfield was absorbed by Goodyear in 1935.

– In 1898 “The Goodyear Tire & Rubber Company” was founded, and based in Akron, Ohio. Charles Goodyear’s name was borrowed – he had no association with the company.  The company initially made rubber horseshoes, bicycle tires, and solid carriage tires.  The Goodyear also made airships (or blimps) and balloons.  The company is still independent, still in Akron and is the 3rd largest tire maker in the world at present.

– In 1900 Firestone was founded in Akron, Ohio (like BF Goodrich, Uniroyal and Goodyear before it) and initially began making solid tires that mimicked The Rubber Tire Wheel patent without breaking it.  Henry Ford began sourcing his rubber tires from Firestone, in 1906.  The Japanese corporation Bridgestone bought Firestone in 1988.

– In 1915 General Tire began life as “The General Tire & Rubber Company”.  The company was founded in Akron,Ohio of all places, by a previous Firestone franchise owner and some previous Firestone employees. General Tire was absorbed by the German tire maker – Continental AG in 1987.

– By 1921 there were at least 330 tire companies in the world.  This is but a very short list of some of the bigger and more noticeable tire companies.  Several of these large successful rubber companies began by making solid rubber tires for coaches, buggies and velocipedes.  A bicycle is technically just a special type of velocipede; the first ones being called “safety bicycles” because they were definitely safer than penny farthings.  In America the rubber importers that specialized in tires were concentrated mostly in just two locations, where access to shipping lanes was important.  First in Naugatuck, Connecticut where Uniroyal was formed by the merger of nine smaller rubber companies, and second in Akron, Ohio – which is not on the shoreline of Lake Erie, but has access to the Atlantic Ocean via the Saint Laurence Seaway.  Akron was once a center of airship development (because of Goodyear blimps; and two Zeppelins were built there for Germany) and was nicknamed the “Rubber Capital of the World”.

– In 1931 Japanese tire maker Bridgestone was started up by an owner of a clothing company.  His first notion before tires was to dip the traditional Japanese “tabi” socks in rubber so that they could be worn outside as work shoes.  Today these are called “Jika-tabi”.  The company made tires for the Japanese military during WWII and afterwards made bicycles, mopeds and tires to fit the same as well as motorcycle tires.  Bridgestone bought Firestone in 1988 and now the 90 year old company is the second largest producer of rubber tires in the world.

Roads

  Long before the advent of the automobile, some streets in larger cities might have been cobble-stoned or paved with brick.  But the quality of road surfaces quickly diminished in direct proportion to distance from those cities.  An unimproved dirt road outside of town usually became a nearly impassable quagmire following a rain, and in winter that dirt road remained wet longer than it would have in warm weather.  The Romans realized this two thousand years ago.

  There is an old idiom that states: “All roads lead to Rome”.  While the expression can have multiple meanings, primarily it was an observation that Rome was the hub of a sprawling road system.  The Romans built these quality, hard packed paved roads for sensible reasons; to promote commerce, to allow their legions to travel swiftly throughout the empire and also to occupy or employ their legionaries that might have gone idle otherwise.  At its peak Rome had 113 provinces,  372 roads interconnecting those provinces and 29 great military highways radiating from the capitol itself.  In fact the Romans constructed some 50,000 miles (80,000km) of superior hard packed roads throughout their empire.  Their best paved highways were called “via munita”.  The Romans built less expensive gravel roads too, called “via glareata”; most of which are paved over now.

  As centuries passed and populations grew, the need for more roads increased.  Unlike the wide wheels on wagons used for hauling freight, carriage wheels for hauling people grew progressively thinner and more lightweight.  Light weight meant less work for the draft animals and increased speed.  Carriage wheels were usually tall too, because tall wheels rolled easier.  Affluent travelers riding in quick horse drawn, spring suspended barouches, borughams and cabriolets wanted roads with hard surfaces; for speed and comfort.  They did not want their narrow coach wheels to sink down into road ruts or mud.

  John McAdam was a Scottish engineer who’s name became particularly associated with road surfaces.  Looking for a more economic method to construct hard roads than the preceding Romans or other road builders used, he importantly focused upon water drainage to keep the road surface dry.  The “macadam” road that he pioneered and that is named after him even to this day; was built up higher than the surrounding soil, had drainage ditches on both sides and was humped or cambered in the middle.  Initially he used two courses of crushed gravel; specifying that the bottom course of gravel be of 3” gravel (depth 8” thick) and the top course of 1” gravel (layer 2” thick).  Significantly, the gravel he specified was not just any old round river gravel but specifically crushed gravel; which would compress and interlock together.  There were no mechanical rock crushers in those days so teams of laborers crushed the rock by hand, using hammers.  Later on other road engineers would add fine stone dust (leftovers gathered from rock crushing) and water to the road top, before using weighted rollers to compress the new surface.

  When faster moving automobiles arrived, they sped over these macadamized roads and succeeded in pulling up a lot of dust from the surface.  Because of that dust, successive road builders began to apply binders like coal tar, oil, or viscous petroleum tar to the surface of what are still called “macadam roads”.  “Tarmac” was originally such a road, with asphalt oil (tar) poured or sprayed over the gravel and then everything covered with course sand or “crusher fines”.  Asphalt is the heaviest petroleum fraction, and is the last thing left behind after petroleum distillation.  The word tarmac is also associated with airstrip runways, regardless of the paving technique used at airports now.  Using heat to make the sludge more viscous, today’s “blacktop” or “asphalt paving” is mixed from fine crushed gravel and asphalt tar, to a uniformity, before being “lay-ed down” and rolled out.

  Today we have millions of miles of good hard surfaced roads, leading off in every which direction imaginable.  We have developed fast and sophisticated vehicles to exploit those good roads but mainly those vehicles are utterly reliant upon having prepared roads.  For travel over worthwhile distances, modern vehicles are simply not optimized to negotiate soft, uncompacted, unimproved dirt.  Even the brawniest looking, balloon tired “off-road 4×4” will have a miserable time negotiating mud for any distance.  Yet yesteryear’s pioneer wagon, drawn by ox or mules did this successfully; day in and day out.  Without roads or bridges or refueling stations, those wagons circumvented rocks and trees, rivers and streams and canyons and mountains.

  Just as new developments in automobile technology are shared across the oceans today, wagon technology was shared or imitated between nations in the past, too.   In the 18th century there would have been few differences between a freight wagon in France or Germany and a counterpart in America.  Passenger carriages however, differed a little more widely.  The fancy, ornate carriages like those owned by the elites in Europe were far less common in America because they were impractical, considering the overall lack of decent roads.  In America there was not a preexisting road system (often built atop the labor of thoughtful Romans from centuries before) so American passenger coaches and personal buggies were usually less refined and more austere than those in Europe.

Freight

  A large, unique type of freight wagon called the “Conestoga” would be developed by German immigrants in Pennsylvania; long before the American Revolutionary War.  Like wagons elsewhere intended for freight, the huge Conestogas had no seat or provision for a rider, but the driver, muleskinner (occupational cuss-er) or bullwacker (ox driver and professional cuss-er) generally walked alongside on the left side of the draft animals.  Thousands of Conestogas (and wagons copying the style) were made between the early 1700s and the arrival of railroads much later.  The typical Conestoga weighed about two tons empty and could carry about six tons of freight.  The boat hull shaped “box” of an authentic Conestoga was usually painted blue and the “running gear” and wheels were red.  The uniquely shaped box was typically 3’10” wide and 12′ long at its bottom and 16′ long at the top.  With its canvas cover included, the wagon stood over 11′ high.

  East of the Mississippi river, teams of four to six horses were generally adequate to pull the heavy freight wagons.  But west of the Ohio river valley and onward towards the riverfront/ frontier town of St Louis and beyond, mules and oxen soon became the favored draft animals.  Mules simply made better draft animals than horses; had more stamina and endurance, thrived on lesser quality food and had less health problems than horses.   Indians didn’t care to steal mules either.  As a draft animal, a good mule was worth two or three times that of a horse.  Mexican bred mules were to become the most desirable and curiously, were generally thought to be more intelligent than others.    Likewise oxen (any cattle that have been trained as draft animals) were often preferred by teamsters.  An ox was slower than a horse or mule, but day in and day out it got the job done – and for far less cost and maintenance.  Oxen became the most common draft animals for pulling freight; simple economics.

     

  After an underappreciated French explorer and frontiersman (Pierre Vial – in the 1790s) pioneered what would become known as the “Santa Fe Trail”, an important pipeline of freight commerce between central Missouri and California would ensue.   Following the Louisiana Purchase (1803), the Mexican-American War (1846-1848) and the California Gold Rush (1848 – 1855) the sporadic traffic over the 800 – 900 mile long Santa Fe Trail, burgeoned into a veritable traffic jam by the standards of the day.

  The largest and eventually most popular freight wagons used on the Santa Fe Trail were known as Murphy wagons.  Theses quality made, heavy duty wagons were constructed of the best materials, by Joseph Murphy of St. Louis. Murphy’s first wagons were freight wagons for the Santa Fe trade, sold @ $130.00 each.  They mimicked Conestogas but were made even larger and stronger to haul more freight; instigated by need because of a very high tax imposed upon single wagon-loads, by the corrupt Governor of the Mexican territory at the time.  The largest of these wagons had boxes that were 16′ long, 8′ wide, 7′ deep and could easily carry 10 tons of freight.  The rear wheels on these wagons were sometimes 10 ft. tall and 8 inches wide to provide more flotation in sandy or soft soils. The Murphy iron tires were made double thick.  Teams of at least 12 oxen were commonly used to pull the big wagons.

_* If one were to compare the freight hauling capacity of a modern day “pickup truck” to one of these old fashioned wood wagons – he might be surprised by a few simple facts.

– Forty years ago a “½ ton” truck rating usually meant that a given pickup could accommodate 1,000 pounds of freight (or weight in the back) without breaking.  Today pickups are built heavier and stronger and so can usually safely handle payloads bigger than that.  The government has specified eight general classifications of trucks based upon what they call GVWR (Gross Vehicle Weight Rating).  GVWR is the sum of the truck’s own weight (curb weight) and what it is expected to carry safely (payload).  The payloads in GVWR ratings are generally underrated significantly – to err on the side of safety.

– Using the popular Ford F-150 pickup as a typical example of a “full sized”, ½ ton, light duty truck; it would be determined that it fits into Category 2, because of a GVWR floating around 8,500 lbs.  The curb weight near 4,900 lbs and the payload nearer 1.4 tons, than ½ ton.  A heavier F-250 (¾ ton) pickup might rate right at the cusp of Category 3 with a curb weight of 6,586 lbs, a payload of 2 tons (4,260 lbs) and a total GVWR of 10,864 lbs.

_ So if that conservative estimate of payload for a ¾ ton pickup were bumped up some, today’s heavy duty pickup might be able to handle without breaking; almost one quarter of the weight that an old fashioned freight-wagon (made mostly of wood) was dealing with every day.

The Cart

  On the other side of Santa Fe, using just two wheels to come up from the south, was a different type of freight vehicle called a “carreta”.  The oldest road in the continental US is the “El Camino Real” (“The King’s Highway” or “The Royal Road”).  The entire four hundred year old – 1,600 mile long route extended from Mexico City to a little northwest of Santa Fe.  Only 25% of the route lies within the US boundary.  The route was blazed 1581. 

   Seventeen years later in 1598, Juan Juan de Onate would lead a colonial expedition over the route.  Among these first settlers were “129 soldiers and their families, Franciscan friars, farmers, laborers, servants and slaves”.  Some 83 primitive and ponderous “carretas” (2 wheeled carts) were used.  In the centuries to follow, the large ox drawn carretas and increasingly some mule drawn wagons too, assembled together in Mexico City to form large “conductas” (caravans) for their annual supply and trading trip to Santa Fe and back.  Sometimes hundreds of people and thousands of animals would accompany the caravans.  Since the one-way trip took about 6 months, the cycle between round trips was probably more like one and a half years.  The big ox drawn carts were notoriously noisy; their squeaking could be heard from miles away before they arrived.  The primitive wheels were not intended to be removed and there was no metal or grease between axles and hubs to reduce friction.

   

  The “El Camino Real de Tierra Adentro” (the royal road to the interior lands) was closed down for a dozen years, between the “Pueblo Revolt” (1680) and the “Reconquista” (1692).  Between the 1770s and 1820s, caravans were conducted by private contractors that preferred to use trains of pack mules, rather than carts or wagons.  Before the 1820s, contact or commerce with American colonies had been vigorously discouraged by Spain.  When Mexico won its independence from Spain (1821); trading with Americans opened up.  New Mexico was only a part of an “independent Mexico” for 25 years.  Following the war between Mexico and the US (1846), the 400 mile long American section of the Camino Real down to El Paso at least, saw consistent use of the same large Murphy type freight wagons which were also being used going northward on the Santa Fe Trail.  Until the railroad arrived in 1881, anyway.

   The “Llano Estacado” or “Staked Plains” is a big 30,000 square mile flat spot between Texas and New Mexico.  The plateau might have been named for the long escarpments along its edges or it might have been named for explorers or settlers marking off distances with wood stakes or piles of stone, to delineate boundaries decreed by Spanish land grants. 

   Irregardless of how the name did originate, it brings to mind a simple way of marking distances that some settlers apparently used.  By tying a knot of rope around the rim at one place on a cart or wagon wheel, each rotation of the wheel during travel would leave a mark in the dirt; and meanwhile the rotations could be easily counted.  Providing the wheel was of a certain diameter, then relatively accurate measurements of distances could be made.   Every furlong in a survey could be marked by stakes or other markers.  A pile of white buffalo skulls might have made good mile marker, visible from a distance on the Staked Planes.

 * Old Spanish units of length were usually a little shorter than the traditional British Imperial units that Americans still use.  A Spanish “vara” in Texas measured only 33 inches; compared to a normal 36 inch “yard”.

* Considering that circumference =[ 3.14159  x  d] then a wheel 5.25 ft. tall, would accurately measure the distance of one “rod” (16.5ft.) with each revolution.

 * In medieval times, acreage was determined by the amount of soil that a team of oxen could comfortably plow in a day.  Since it was difficult to reverse directions with a team and plow, the acre was originally conceived as being a rather long but narrow rectangular plot, rather than being square.  The acre was defined as an area one “chain” wide, by one “furlong” (10 chains) long.  There are 4 rods in a chain and 10 chains (40 rods) in a furlong (a furrow is long).  The rod again being 16.5 ft., meant that the idealized acre (1 chain x 10 chains) or (4 rods x 40 rods) equaled (66 ft. x 660 ft.) or 43,560 square feet.  Also: there are 8 furlongs to the mile and 640 acres to the square mile.

 

  In the 19th century there were literally thousands of different wagon and coach makers in America.  Some of the wagon manufactures worked out of little more than small blacksmith shops but about 20 or 30 of the larger wagon companies employed hundreds or even thousands of workers.  America needed and therefore built more wagons than any other country during the 19th century.  Immigrants flocked to the nation by the millions because of the perception that a continent full of empty land was free and available for the taking.  But becoming a pioneer and preparing for a long, perilous overland journey required a sobering investment in both time and money saved.  Dependable wagons and draft animals were hugely expensive investments for families that might have earned less than $30 income per month.  

  Between the 1840s to the 1860’s the “Oregon Trail” was a trip through the wilderness made by perhaps 300,000 to 400,000 people.  It took about four to five hard months to complete the 2,170 mile journey (from Independence, Missouri to Oregon City, Oregon).  It should be safe to say that tens of thousands of “prairie schooners” made the trip.  A prairie schooner or “covered wagon” was a uniquely American style of wagon.  It was generally like a Conestoga wagon but cut-down to about half that size.  Since wagons were made by many different makers, they varied some in shape and feature and durability.  When investing in a wagon for crossing the wilderness, the smart buyer would no doubt have chosen one that could serve as a dependable tool once the final destination was reached.

 

   A typical prairie schooner-covered wagon could carry about 2,500 pounds of cargo and still be pulled by 4 to 6 oxen.  Large diameter wheels in the back made the wagon easier to roll over obstacles like logs, rocks or creek bottoms; while the smaller wheels on the front axle allowed the wagons to turn sharply.  The sheets of cotton canvas draped over the wagon tops, looked like ships’ sails in the distance; hence the name ‘schooner’.  The cotton duck canvas canopies were usually an undyed natural white (as were most ship sails).  The canvas obviously protected food and goods from the elements but it also made a very useful emergency shelter for people.  

 * The textile term “duck” comes from the Dutch word doek, which refers to a linen canvas once used for sailors’ white trousers and outerwear. Duct tape, often erroneously called “duck tape,” was nonetheless originally manufactured by adding an adhesive backing to regular cotton duck.

   

    The first stage line in England started up more than 400 years ago.  Independent stage lines existed all over Europe and all over eastern America before they showed up in western America.  Stagecoach lines were equivalent to the public bus lines of today and in many places they were contracted to carry the mail.  “Stages” of course were segments of a route, where every 10-20 miles the coach would stop to rest or exchange horses and people.  In the American west or in other remote, isolated locations where people still wanted to travel and could pay, stage lines continued to operate into the 1920’s.  By that time rail roads, affordable automobiles and motor-buses, displaced the stagecoaches.  Neither did all stagecoaches look as good nor were they as comfortable as those seen in Hollywood’s western films.  The Concord coaches seen in most western movies, would have been considered luxurious for their era, and were not as numerous as the less expensive but equally functional vehicles were.

   

* At one time four different companies made “Concord Coaches” (in Concord, New Hampshire).  The best ones were made by Abbot & Downing and their reputation was such that they exported their coaches to places like Bolivia, Australia and South Africa.  Beginning in 1827, Abbot and Downing’s coaches were styled from contemporary English coaches, but added several improvements; especially including the suspension of the whole coach body well above the axles – on long leather straps known as “thoroughbraces”.  This improved suspension changed a normally bumpy ride into a more tolerable rocking chair like motion. 

   Whether made by Abbot & Downing or not, coaches from Concord, New Hampshire were made in 6, 9 and 12 passenger seat models.  Some models had running lamps and glass windows; those used in the west usually had no glass, but unbreakable leather curtains that could be rolled up or down.  The exteriors of these lavish coaches were decorated with custom scroll-work trim and with paintings of landscapes, while the interiors were lined and upholstered with comfortable russet leather or plush (a fuzzy velvet like- nap or pile).  A full bodied Concord stagecoach for 9 passengers would weigh 3,000 lbs., carry 4,000 lbs. and cost $1,400.  Some of these luxury coaches have been restored or have been protected from the ravages of time; and now outnumber the utilitarian versions that were once more common.

  As stated earlier, less comfortable, less expensive and lighter coaches called “Celerity wagons”, “mud-wagons” or “stage-wagons”; would have been drafted to do the majority of work for stage lines.

   Another major artery of westward migration was first called “Cooke’s Wagon Road” and later the “Gila Trail”.  Pioneers with covered wagons were not so numerous on this route as they were on the Oregon Trail, but thousands of adventurers did use it; especially early prospectors from southern states in a hurry to reach the gold fields in California.  The Gila Trail (or Kearny Trail – a military road carved and made wagon passable by Lt. Colonel George Cooke and his temporarily indentured Mormon Battalion in 1846-47) ran about 750 miles from Santa Fe, NM to San Diego,Ca.  The Santa Fe Trail and the Gila Trail together (900+ 750 miles) became the primary communication link, stagecoach transportation and freight-supply route back and forth from California to the rest of nation in the east.  A route open year around because it did not get blocked by winter snow.

Mail

  Mail contracts were lucrative and sometimes a more steady revenue than passenger service. See the ***Star Route Service***.

  The San Antonio–San Diego Mail Line was the first company to carry US mail from southern California; (in stagecoaches, over part of the Gila Trail) to southern Texas.  The “Jackass Mail” operated between 1857 and 1861, took 30 days to make a trip one way.  Until way stations were established, the first few mail deliveries were made by pack mule.  But as one northern California newspaperman complained, the San Antonio–San Diego Mail “ran from no place, through nothing, to no where”.

  Butterfield and Company’s “Overland Mail” carried mail back and forth to California over the Gila trail, on a much more regular basis.  From 1858 to 1861 (the beginning of the Civil War) it took an individual letter or passenger (from San Francisco) about 25 days to reach either St Louis or Memphis or vice-versa.  The route to either was about 2,800 miles (462 miles from San Francisco to Los Angeles – then about 2,238 more to either St Louis or Memphis (which are north and south of each other, on the same river and about 240 miles apart).  A stagecoach in the twice weakly service, averaged 5 miles per hour and covered 120 miles a day.  The trip was a physical ordeal for passengers that payed $200 to go west or half that much to return east.

*  John Butterfield owned an operated some 40 small stage-lines in the east.  His name and reputation would be instrumental in winning the $600,000 US mail contract awarded by Congress in 1857.  Butterfield owned only part of the Butterfield “Overland Mail” company; other investors included William F. Fargo and Henry Wells.  Butterfield was forced out by Wells and Fargo in 1860 and they in turn were compelled to move the mail and passenger line northward by the impending Civil War.

  In 1860 the “Pony Express” was begun to carry mail more expediently from northern California to the east and back.  It took 10 days for Pony Express mail to cover the 1,900 miles between Sacramento, CA to St. Joseph, MO.  The route roughly followed the Humbolt Trail and part of the Oregon trail.  It cost 250 times the normal postage rate to send a letter by Pony Express.  The first transcontinental telegraph and arrival of the Civil War, put the Pony Express out of business 18 months later, in 1861. 

 * The holdings of The Pony Express company were then acquired by Ben Holliday who was able to acquire a postal contract for mail service to Salt Lake City, Utah; and who also established the Overland Stage Route (different route than Butterfield’s route to the south).  In 1866 “Wells Fargo Express” purchased the Overland Stage Company from Holliday.   Wells Fargo became top dog; owning both Overland stage lines and the mail contracts in the west.

* Wells Fargo & Company became the world’s largest bank in 2015.  The next year though it sank to 4th largest (after JP Morgan Chase & Company, Industrial and Commercial Bank of China Limited, Bank of America and Citigroup).  Probably because of some shenanigans it pulled. (Wells Fargo created millions of fraudulent checking and savings accounts on behalf of their clients; without informing their clients).

A replica Pony Express “mochila”.  Each of the four pouches had a lock hasp and lock.

* Pony Express riders could not weigh over 125 pounds.  They rode day or night – nonstop except to change horses, at stations roughly 10 miles apart.  There were about 184 stations along the 1,900 mile route; 400 special horses and 80 young riders that switched out every 75–100 miles.

* There was a subtle change some months ago, in the manner that WordPress handled thumbnail enlargements.  Instead of presenting full enlargements, they now present smaller, less satisfactory enlargements (to make room for advertising “App Store” and “Google Play” buttons).  For the many thumbnails to follow;  closing the window and selecting the thumbnail a second time should produce the full picture as intended.

Carriage types

Buggy”, “coach” and “carriage” are in-specific terms that bring no clear image to mind.  Many names in many languages for carriages, have gone unused and are forgotten now.  How many once common terms are still recognizable today?  What were the distinctive differences between a Barouche, Brougham, Buckboard, Cabriolet, Calash, Dogcart, Governess Cart, Jaunting Car, Landau, One-horse Shay, Phaeton, Sulky and a Surry?  Following is just a representative sampling of some of the better known carriages types.

_ A Barouche was a luxury 4-seater, where the passengers faced each other.  The carriage driven by a coachman in the back, is open although usually a collapsible half-hood could be pulled up over the back seat.

   

_ A Brougham was an English, light, enclosed, glass windowed four-wheeled carriage.

_ A Buckboard was a very minimal utility vehicle usually pulled by one horse.  Having 4 wheels, a seat and a few boards connecting the two axles together.  Unlike other carriages, there were no springs between the axles and the platform of boards.  What suspension there was came from the flexibility of the floor boards and (usually) leaf springs mounted under the bench seat.  Between the boards flexing and the springs, a ride over rough terrain could get very bouncy (hence buck). 

  Later wagons might be called buckboards yet have upright boards along the edge of the bed to hold cargo.  These later wagons would generally still have no suspension other than the springs under the seat.  The buckboard was the forerunner of today’s mini or economy pickup; useful for running into town and back real quick – to pick up the mail, some groceries or something from the hardware store.

   

_ As stated earlier, “buggy” is a very general term.  Usually it means a very lightweight vehicle for one or two passengers and pulled by one or two horses. Some Amish communities today build buggies, which are legally equipped to use today’s road systems.  The newest Amish or Mennonite buggies might feature a triangular – slow moving traffic warning sign, reflectors, manual windshield wiper, rear view mirrors, iron axles, drum and even disk brakes and sometimes even a small battery and electrical system for blinking turn indicators and LED headlights.

 

_ A Cabriolet was a light two wheeled carriage for hire, that was pulled by one horse. Originating in France the cabriolet was similar to a “Shay” except for the driver or groom which stood or sat overlooking from the back of the cab.  The terms taxi-cab and hansom-cab come from the shortening of cabriolet.

   

_ A Coupe was a stylish carriage with a sloping body style, driver in front, bench seat for two passengers in enclosed cab, with windows on sides and front to look out.  Longer and with more visibility than a brougham.

_ Coach has become a vague term, usually meaning any large heavy vehicle intended to carry passengers.  A proper “state coach” as used on ceremonial occasions however, were usually heavy and non-maneuverable and therefore ponderous enough to not outpace the footmen that walked alongside them.

 

_ A Dogcart was originally intended as a lightweight transport for game hunters and their sporting dogs, which were carried in a box underneath the driver’s seat.

 

_ A Governess cart was a small washtub shaped cart that was safe for a lady to use.  With a low center of gravity and with a gentle pony to pull it was unlikely to tip over or to allow young children to fall out.

 

_ Jaunting car was another 2-wheeled cart, pulled by a single horse; a pleasure vehicle for short excursions.  The driver sat forward but the passengers sat back to back, with their legs hanging out over the wheels. Like the governess cart, the jaunting car was once very popular in Ireland.

 

_ The Landau is a luxury 4-wheeled carriage that is usually open topped, so that passengers can see out – but more importantly so that they (VIPs) can be seen by the public.  The landau can accommodate 4 passengers – sitting face to face (vis-a-vis).  The landau is similar to a barouche or “victoria” but differs in being a little heavier and more stately; and in possessing a full roof, which can be pulled up to protect the cab.

   

_ The Phaeton and shay both were stylish and tall wheeled but delicate buggies.  Phaetons had 4-thin wheels while shays had only two.  In the later part of the 19th century fashionable phaetons and shays were to become very popular runabouts in urban areas of America, where hard packed roads were becoming more common.  Requiring usually only one horse, they were very lightweight and fast, but dangerous.

_ The Shay was a 2-wheeled cart that was pulled by one horse. The word “shay” comes from the French word for chair (chaise).  What makes the ‘one horse shay’ different than the typical “gig” is that the shay should have a collapsible folding hood (or “calash top”).

   

_ A Sulky or “spider” or “bike” is a very minimal 2-wheeled cart used in harness racing.  Today’s racing sulky has morphed into a low to the ground, small wheeled cart, where the driver sets so close to the back of the horse that he is in a position where he is unlikely to get kicked hard.  There are two classifications of harness racing on most tracks; dependent upon the gait of the horses (trotter or pacer).  A trotter moves diagonally paired legs simultaneously, but pacers move the legs on the same side of their bodies together.  Trotters and pacers don’t compete against each other because pacers are a little faster and trotters cannot be trained to pace.  The disposition of a pacer to move its legs in the unusual way it does, has recently been traced to the mutation of a specific gene.  A harness race video.

   

_ A Surrey is a simple English inspired, 4-wheeled carriage with two forward facing bench seats, accommodating 4 people.

   

_ A Tarantass was a very long chassis style of coach used in Russia.  Without using springs, suspension was achieved by the weight of the cab flexing long poles that connected front and back axles.

_ A Troika is less of a carriage type than it is of a peculiar type of Russian, horse harness.  Whether a sleigh or wheeled carriage, a troika is distinguished by having three horses harnessed abreast.  The center horse is positioned between shaft poles (as would be common for any single horse rig) but in addition might also be harnessed with a breastcollar and a “shaft bow”.  The (Baltic) shaft-bow acts like a spring – pulling the shafts outward, theoretically improving workload conditions for the horse.

   

 

Anatomy of a Farm Wagon

  One particular type of wagon became almost ubiquitous in America before the takeover by automobiles.  In an age when more than half the country’s population lived on rural farms rather than in cities, almost every farm in every state – owned a work wagon.  Perhaps called a “grain wagon” or a “buckboard”, this plain looking, utilitarian vehicle was the forerunner of the pickup truck.  Farm wagons were made by the tens of thousands every year, by multiple manufacturers and often shared ‘off the shelf’ metal components in their fabrication.  This type of wagon was still in demand and still being built into the 1940s, because metal was needed for the wartime production effort and gasoline at home was being rationed.  Rare was a farm wagon that did not have red wheels.  A “mountain wagon” looked similar but was of even heavier duty construction.

  The illustrations nearby show wagons with boxes two high (roughly 2 – 2” x12” boards high); but configurations of one box or three boxes were just as common.  Attached simply to the bolsters and bolster uprights, these boxes could be removed easily, so that the wagon could be reconfigured.  Removing the bed or box would allow the bare “running gear” to haul long lumber or raw logs for example.

  The running gear in these illustrations are of a later model Studebaker, which would represent a fairly ideal example of what a wagon with wooden axles and wooden wheels should look like.  But the running gear of 20 other farm wagon makers would have looked much the same.  *‘Studebaker Brothers Manufacturing Company’ became big after contracting to supply wagons to the US Army during the Civil War.  At one point Studebaker was the largest coach-building company in the world.  Because they made quality products.  A barouche, landau and a surrey in some of the pictures far above for example; were made by Studebaker.

  The metal used in wagons and carriages was kept to a minimum to limit weight.  Most wagon makers would have sourced some metal components from suppliers or industries that specialized in metalwork.  Parts like king and queen bolts, 5th wheel or bolster plates, lag bolts, hub nuts, cast iron skeins and hub boxing inserts.  (These parts might have been supplied by metalworking manufacturers perhaps like John Deere & Company; established by a blacksmith who in 1837 pioneered the first self-scouring steel plow.  Or metal parts from International Harvester – a company co-founded by Cyrus Hall McCormick – who had demonstrated an influential horse-drawn reaper in 1831).  One thing for certain is that before the Civil War there would have been very few if any small town blacksmiths and wainwrights equipped with the expensive lathes needed for turning their own screws or threaded nuts and bolts.

  Somewhere back in the 1850s the first iron “thimble skeins” were invented.  These skeins (reminiscent of a sewing thimble to fit over a person’s finger) fit tightly and were lag bolted over the end of a wooden axle.   The end of the skein is threaded.  Running on and contacting the skein would be a metal “boxing”  – which was pressed into the wheel’s wooden hub.  A wrench would be needed to remove a hub nut and washer, before the wheel could be removed; so that the axle could then be lubricated.  When properly lubricated with axle grease the skein/boxing interface produced minimal friction.  It’s doubtful if tapered roller bearings would have preformed any better, had they existed.

  This very practical German ladder wagon looks like it’s holding a tank for water or possibly milk.  With the tank removed the wagon could be used to haul hay, or be reconfigured in several different ways.

_* Friedrich Fischer (German) invented a process for milling standard ball bearings in 1883.  Henry Timken (US German immigrant) invented the tapered roller bearing in 1898.  The boxing style axle worked just fine though and wheel bearings were seldom used in wagons or buggies even after their invention.  Automobiles, yes.   Wheel bearings are being used now in most modern buggies however.

  Before the 1860s and before the proliferation of thimble skein axles – wagons used what are called “clouted axles” or “lynch pin axles”.  A clout was “an iron plate let into the arm of a wooden axle’s underside to take the wear of the box in the revolving wheel”.  There might have been a clout inlaid into the top of the wood axle too.  So clouting the axle arm was “arming the arm of the axletree with iron plates to keep it from wearing”.  A hole was drilled at the tip end of the axle so that a lynch pin or cotter pin and washer, could hold the wheel on.  Wagons made from the 1700’s and before the 1860s, also probably had metal boxing in the wheel hubs – to ride on the clouts.  Conestogas in the east and prairie-schooners going over the Oregon Trail (1840s-1860s) would have had these lynch pin type axles.  Those axles need to be greased frequently, therefore a grease bucket accompanied most every wagon; usually slung from the rear axle.

_* Grease was hard to come by and therefore was used sparingly on pioneering wagons.  Usually it was made from saponified tallow rendered from beef or mutton.  Pine tar (from the distillation of turpentine) if it could be acquired was often used to preserve the animal tallow grease.

_ In the picture above (a) is a lynch pin/clouted type axle.  (b) would be a later, skein and threaded hub nut type hub and axle (incidentally the threads on the right side would tighten in the normal clockwise or right handed twist method, but on the left side of almost all such wagons it was convention to reverse the threads. The theory was – that since the wagon moves forward predominately that counterclockwise threads on the left side, kept the nuts snug and the wheel from falling off)(c) are examples of the very influential “Sarven hub”, patented in 1857.  These hubs, sandwiched spokes tightly between flanged collars and by doing so allowed for improved, thinner carriage wheels.  Sarven style hubs quickly became dominant and are manufactured today.  (d) examples of the “Archibald hub”, also frequently called an “artillery hub”.  Archibald hubs look like beefed up and burlier improvements of the Sarven hub but the two might have co-developed at the same time.  Stout Archibald hubs along with iron axles are found on almost all US Army wagons made from the 1870s onward.   It seems that “artillery wheels” predate both types (Sarven and Archibald) by several decades (e) Hubs from a 1913 Ford Model T; identical in manufacture to some artillery wheels.

  Unlike wagon wheels with iron tires that were deformed into a concave dish shape by the shrinking metal when it was cooled, the even stronger artillery wheels didn’t necessarily have that concavity.   The way that the hefty spokes were mitered and jammed together tightly in a locking keystone fashion, left no slack in the center.  Hot iron tires might have been fitted in the normal manner, but the wheel did not deform.  In addition the tires were often bolted to the felloes of these wheels anyway.  Artillery wheels needed to be extremely strong.  Iron and bronze cannons were extremely heavy.  On the battlefield, wheeled cannons were often hurriedly dragged to location by teams of horses and then wrestled into position by teams of desperate men, who often grasped at the wheel spokes to yank a heavy cannon around in the mud.  You don’t want such a wheel to come apart in your hands.

 

  Napoleon was employing “shoot and scoot” tactics, using lightweight “horse artillery” some 200 years ago.  Of course Napoleon picked up some of his ideas from “Old Fritz” (Fredric the Great) who had created the first regular horse artillery units, a generation before.   Differing from regular field artillery that was also horse drawn, horse artillery units were a hybrid of cavalry and artillery.  These mobile and fast moving units usually worked in unison with cavalry, lending fire support.  Crews were trained to dismount, shoot some, remount and then split as quickly as possible.  For example horse artillery could be used to arrive from seemingly nowhere, shoot into and break up enemy infantry formations on the march, which then allowed friendly cavalry to rush in and attack the disarranged enemy.  In the meantime the cavalry attack would give the horse artillery the opportunity to pack up and leave.

 

   Horse artillery units could usually be distinguished from heavier artillery units by the smaller size of the cannon they pulled but also by the fact that everyone in the unit was mounted on a horse.  By contrast, in regular field artillery units some of the crew-members rode on the limber or caisson. A limber was a two wheeled axle or cart that the tail of a cannon was hitched to and supported by, during transit.  A caisson was a little bit bigger than a limber, and usually could be used as a limber, if need be.  A limber usually carried one ammunition box and trailed a cannon or caisson.  A caisson carried two ammunition boxes and required its own limber (total of 3 boxes).

  Typical support for one field cannon then; was a crew of at least 6 men, one caisson, 2 limbers and 4 boxes full of cannonballs and gunpowder.  Emptied of their boxes and other cargo, the limber and caisson combination was frequently used as an ambulance to carry casualties to the field hospital or in recent times to carry caskets in funeral processions.

   Some of the prefabricated iron parts that independent farm wagon makers might have sourced rather than forged themselves were the “bolster plates” or 5th wheel.  The bolster plate was an evolution from previous and simpler iron straps mounted to the top of the “sand board” and the bottom of the “front bolster”.  Eventual improvements to the bolster plates made them round and wheel like, so the assembly became known as a 5th wheel.  This was the pivot point that the king pin ran through, where the reach to the back axle connected and where the front axle was allowed to turn.  Whether circular or not, bolster plates are often called 5th wheels, retroactively.

    The quick connect / disconnect couplings found on modern highway truck tractors and goose-neck trailers, inherited the “5th wheel” name from wood wagons made 4 or 5 generations ago.  The rugged lunntte ring and pintle hook tow hitches used by modern military trucks and off-road enthusiast, were used by horse drawn artillery carriages centuries ago.

 

Miscellaneous images

 

  This illustration was done during the grand opening of the Palace Hotel in San Francisco in 1875.  The inset in the upper left of the picture shows arriving or departing coaches in the interior, sky-lit Grand Court entrance.  No traffic control in the streets.  Several types of carriage are visible outside in the street; including a landau, a barouche, a brougham and a shay.

   There are many different ways to rig effective harnesses.  A collar that fits over an animals head and neck, is the soft padding and the second part of the collar system is the hames – made of wood or metal and featuring rings or attachment points for trace lines and other straps.  Alternatively a breast collar suspended by a neck strap might carry the pulling load.  A small padded saddle suspends the two buggy shafts.  Trace lines from the collar pull the buggy but breaching over the horse’s rump prevents the buggy from running into the back of the draft animal on downgrades or stops.   Terrets are simply rings on the harness that guide reins.  An overcheck or check-rein runs over the top of a horses head while a bearing-rein might run lower at mid jaw; both are intended to control the horses head – preventing it from dropping too far.

      The yellow lines approximately depict the middle mass of a horse, and also the place (at the withers)  where additional weight should be distributed.  The sulky in the 1st photo is being suspended by, and being entirely pulled by contact with a tight bearing strap and girth. The breast collar on this animal might as well not be there.  In the second picture, the jockey maintains a high balanced position above the center mass of the horse.  Notice how short (high) the stirrups are.  During a race the jockey makes no contact with the saddle seat but rides with his legs.  At the start of a race the jockey’s position is shifted far forward while the horse is accelerating.

 

All manner of beast have been put to the test as draft animals.

  Usually the biggest and strongest animals of a 4 horse or larger draft team, will be at the back, nearest the wagon or carriage.  The “wheelers” support the wagon’s tongue or center pole and also commonly carry the only breaching straps.  The “leaders” in front seldom support a center pole between them and therefore may or may not have full collars.

 

 

Splendid transitory shelters

  Above is a little page construction built with the intention of quickly explaining the design elements for one specific type of dome.  A physical photograph of this image along with a few other photographs is intended to accompany a disassembled dome kit.  To act as a short explanation and little assembly manual for the dome’s reconstruction.

  Geodesic domes are curious innovations.  The fact that they are strong and can cover a huge volume of space economically, often makes them smartly utilitarian.  They are generally not practical platforms to work with however when considering insulated dwellings like homes or offices.  Materials for modern construction often come in thin, long rectangular shapes or in squarish block forms that resist adaption to curvature.  The chore can be done but details of construction benefiting a personal home like wallboard, cabinetry and trim can become nightmarish for the builder of a proper dome house.  Where domes do shine is in expeditiously enclosing a large volume of internal space while using materials frugally.  As a result most domes are often spacious but thin walled.  Depending upon design and components used they can make good temporary or transportable structures.  Many splendidly large domes have been built in the last six decades but unfortunately, of these many have been torn down.  Some were built as displays for World Fairs or Expos and still survive in a partially changed or re-purposed state.  Other large, pioneering dome examples went neglected and unused until they finally needed to be taken down.  Going back to analyze the biggest or most influential domes led to a re-discovery and investigation of the first great, humongous but temporary greenhouse in history.  The enormous, awe inspiring and refreshingly fanciful Crystal Palace hosted the “Great Exhibition” (the first World’s Fair) almost 170 years ago.

Octagons Don’t Tessellate

  There is a great number of mathematical ways to for the architect or engineer to vary the arrangement of cross-members in the structure of a geodesic dome.  In geometry “geodesic” implies the shortest path between points on a curve.  It takes math to predictably persuade straight building materials to intersect with points on a sphere and still maintain uniformity and structurally rigidity.  You end up using a lot of triangles.  Still, a triangle presents a flat, not curved surface.  In geodesics it is expedient to consider a few regular polyhedrons because they come with polygonal faces and unlike the sphere these 3-dimensional solids are conveniently adaptable to triangulation. 

To expand the plan or size of a sphere or dome it becomes necessary to subdivide polygonal faces into smaller triangles.  This expansion and mapping is called tessellation.  “A tessellation of a flat surface is the tiling of a plane using one or more geometric shapes, called tiles, with no overlaps and no gaps”.  There are only three straightforward “regular tessellations” however, which depend upon three regular polygons (the equilateral triangle, square and hexagon).

  Most geodesic domes constructed will be of Class I type, a much smaller number of Class II and practically none at all of Class III.  It boils down to simplicity and ease of calculating the tessellation.  Only architects, engineers and eggheads like Buckminster Fuller would bother to fiddle with the more complicated constructions.   Buckminster Fuller literally wrote the book on geodesic domes.  He defined criteria and wrote formulae to calculate geodesic dome construction, then sold or licensed this knowledge to architectural firms around the world.  He himself was fond of using the “triacon” (Class II nickname) breakdown for his constructions.  When it comes to the largest domes the triacon offers less confusion for builders than the “alternate” (Class I) breakdowns.  Unlike the alternate, triacon domes or spheres only come in even frequencies but unfortunately these have no great arc equator running down their center-lines.  Importantly the triacon requires fewer different strut lengths; however those lengths may vary a little more.  

* Polygons are 2-dimensional shapes but polyhedrons are 3-dimensional solids.  Both are n-dimensional polytopes.  There is only a handful of “regular” convex polygons but a much larger quantity of irregular, concave and complex polygon types.

* The same holds true for polyhedrons.  You’ve got five regular (even sided, even angled, convex) polyhedrons called “Platonic solids”, thirteen polyhedrons called “Archimedeian solids”, ninety two polyhedrons called “Johnson solids” and then a bewildering number of other possible irregular, stellated / concave polyhedrons that can be considered.  Then for every polyhedron there is a reciprocal or “alter ego” so to speak called a dual.

 

 

*  Within mathematics a whole branch of geometry called “polyhedral combinatorics” can find an absurd number of ways to twist and contort the polyhedra, and it has the notation to describe them all.

  This following picture shows only Class I dome examples and begins with the basic icosahedron which has a frequency of “1” and who’s “Schläfli symbol notation” is {3,5 +}1,0.  The alternate breakdown or tessellation continues to be used as the frequency is increased. 

Unfortunately now one must open; close and then reopen a thumbnail a 2nd time; to view the enlargement properly. 

* This picture above and the 1’st image of this post were concerned with constructing a portable dome from 3/4” EMT (Electrical Metallic Tubing).  In America this galvanized conduit is sold in 10 foot lengths.  That size and length cut in half (5′) is almost strong enough to support the weight of a normal person climbing around upon the dome, without one of its cross-members bending.  For economy of material the dome heights and diameters in this picture are consequent to the longest possible strut (pipe) length being no longer than 5 feet.

* From the picture: the 5/8ths version of a 3v dome is practically as tall as the 4v version that conveniently does have an equator.  However when jumping to 4v the number of different strut lengths doubles, which can significantly complicate the chore of assembly.  It should take at least 2 people assisting one another to assemble a 3v 5/8ths version and at least 3 people to move it because the completed construction would be ungainly and would weigh about 360 lbs. when made out of pipe.

* For the 5v and 6v versions a ludicrous 9 separate strut lengths are required.  Concentration will be required to assemble such a puzzle correctly.  Additionally, working 23 ft. above ground will necessitate the use of scaffolding, a crane or mechanical hoist.

 

Distinguished dome examples

 

       

In 1967 the World’s Fair or “Expo 67” was held in Montreal, Quebec, Canada.  A group of architects and designers known as the Cambridge Seven Associates, Inc. were tasked with the responsibility for creating and furnishing the United States pavilion for that exhibition.  For the structure they decided upon a large geodesic dome.  Fuller & Sadao Inc. (Buckminster Fuller and Shoji Sadao) were hired to plan the sophisticated shell.

     

The dome’s geometry has been described as being a combination of a 32- frequency regular triacon (Class II, method 3) and a 16-frequency truncatable alternate (Class I, method 3).  Below; at the top left of the modified photo the only, easily discernible pentagon in the image is tinted red.

Originally this historic dome was enclosed by transparent acrylic panels. This <7:24 minute video> by Cambridge Seven eloquently documents many details about the historic pavilion.  The dome caught fire in 1976, which destroyed the acrylic but didn’t melt the steel frame.  ‘Environment Canada’ acquired the structure in 1990 and turned it into what is now a museum called the Montreal Biosphere.

 

  

_ Shareable images of Kaiser Aluminum domes are rare on the Internet.  Above is an unexceptional photograph of an aluminum dome, which functions as the community center for Borger,Texas.   Around 1956 the famous industrialist Henry J. Kaiser and Buckminster Fuller joined together to start a company that manufactured and sold aluminum domes like this one.  Several examples still exist – here and there around the globe.  Even today lightweight, economical and corrosion resistant aluminum seems to be the most practical material with which to enclose a large dome.  Erection of these particular domes sixty years ago was very quick because the polygon shaped prefabricated metal panels just bolted together.  This surviving example in Borger, Texas has served as community center for more than half a century.  An identical or kindred example also in Texas, survives as a popular and continuously used theater near Fort Worth.  Two more of these Kaiser aluminum domes (not pictured) long lasted as concert auditoriums.  The Virginia Beach dome was erected in 1957 and taken down in 1994.  The Hawaiian Hilton dome in Honolulu was also erected in 1957, was aluminum, acted as a auditorium with good acoustics and was taken down only in 1999 to make space for a newer building.

   

_ Better copyrighted pictures exist but above are some allowable public domain images of what was at one time – the largest “clear span” building in the world.  It was designed by Thomas C. Howard of Synergetics, Inc. and owned by the Union Tank Car Company.  The dome was built in 1958 near Baton Rouge, Louisiana.  It measured 384 feet in diameter and was 128 feet (> twelve stories) high.  When the real estate was purchased by another company the dome went abandoned and neglected for a couple of decades.  Unfortunately it vanished in 2008.

   

_ In 1964 New York City opened the only Registered (Universal) world exposition to be held without BIE (Bureau International des Expositions) approval.  “Expo 1964” ran for 18 months; three times longer than normal.  A dome large enough to seat 2,100 people was designed by Thomas C. Howard of Synergetics, Inc. and built as a pavilion.  This building later housed the Winston Churchill exhibit in 1965.  After that the dome was dismantled, moved and the frame (only) re-erected to serve as an aviary for the Queen’s Zoo (NYC).  While the dome is not particularly tall, it is a generous 175 feet in diameter.  These few “free to use and share” licensed images above don’t quite do the structure justice.

   

_ Between 1971 and 1973 the United States Naval Construction Battalion (the Seabees) erected a dome at the Amundsen-Scott South Pole Station.  The NSF (U.S. National Science Foundation) only expected to get 10 to 15 years of service life from the structure but it lasted until 2009 before it was taken down.  There were vent holes in the crown of the dome to bleed off excess heat.  Temperatures above freezing would have allowed the structure and its contents to sink deep into the snow. At least the dome blocked the fierce Antarctic winds.  Designed by Temcor Inc. the dome is said to have been based upon a Class-II frequency 14 triacon breakdown.

_ Temcor was absorbed by CST Industries Inc. somewhere around 2009.  The company creates the largest domes in existence and is probably the biggest dome manufacturer and installer in the world.  As of 2009 they’d already installed something like 7,500 aluminum domes or dome shaped roofs, in 72 different countries.   In Long Beach, California a huge Temcor dome sits close to the Queen Mary.  That dome was initially built to house the famously large “Spruce Goose”.

 

The Crystal Palace

_ Quickly assembled buildings providing vast open interiors, did not begin with geodesic domes.  The grandest example of such a building was created six or seven generations ago.   It took only sixteen months from start to finish to design, manufacture and erect the modular Crystal Palace, on site.  It would sit upon some of the most valuable ground in the world.  The humongous and airy glass building was then filled with eight miles of tables, for fourteen thousand promoters which displayed more than one hundred thousand different exhibits.  The Great Exhibition opened May 1, 1851.  It was a grand success.  And profitable.  In the five months before the exhibition ended more than six million paying customers would walk through the Palace’s doors. Then this biggest building in the world at the time was itself sold off,  removed from Hyde Park and reassembled in another location of London.

_ Many great and energetic minds joined to make this well engineered spectacle a possibility.   More credit belongs to one person perhaps than to anyone else – Prince Albert, Consort to Queen Victoria.   Once his notion caught traction with private investors, then the government pitched in and a Royal Commission was appointed to mount the Exhibition.   Meanwhile a separate Building Committee comprised of the most respected engineers and architects in the Empire was formed – to oversee the design and construction of the exhibition building.  Among their demands were that the building be temporary, cheap to build and fast to erect.  After entertaining planning submissions from all over Europe in 1850, they received and discarded some 245 submissions before choosing one.  It was partially by luck that Joseph Paxton’s plan was picked.  Iron and glass “hot houses” (conservatories or greenhouses) were new and fashionable novelties during this Victorian period.  Paxton was certainly not the only adventurist architect that built them.

   

Monkey Closets in the “Retiring Rooms”

_ To “Spend a Penny” was to become a long lived euphemism for going to the toilet.  It all started with the Great Exhibition and the exciting, first ever public toilets.  It cost one penny to rent a Monkey Closet.  Back then a penny was worth considerably more than today; remember Britain had the lower half penny and farthing (¼ penny) denominations of coin.  But a penny here bought a cleaned toilet seat, a small towel and a shoe shine.  By the end of the Exhibition no less than 827,280 adventurers availed themselves of this luxury.

*  Thumbnail above: this was from a magazine or brochure that was printed for the Great Exhibition. The illustration depicts a sampling of bronze cast candelabras, figurines and sculptures which would have been for sale at the event. The first real “Cylopaedia(Cyclopædia: or, An Universal Dictionary of Arts and Sciences) had already been printed more than a century earlier (in England and in 1728).)

_ In its initial configuration the conservatory resembled a huge rectangular flat topped box, having only one lofted transept at its center.  Still this open building was more than one-third of a mile long and more than 2.5 American football fields wide.  In places it was built over and around full sized trees.  Its structural components consisted of ten million square feet of heavy flat glass plus unknown tons of cast iron columns, trusses and trellis girders and unknown tons of wood planking for the second story floor. 

_ The railroad and steam locomotives that brought this material in were new ideas themselves.  Portland cement was new and economical flat glass was new.  It was the diminutive size of the architectural glass itself that ultimately determined the shape and size of the whole building.  The largest plate glass that could be efficiently made at the time measured 10 inches by 49 inches and today it would be referred to as cast plate glass.  Production cost was substantially lessened and construction was simplified because Paxton’s plan was drawn around using millions of these identical panes of glass.  Other parts were mass produced also and some served multiple functions.  The posts and girders came straight from the foundry and could be bolted together to form free standing modules in no time.

_ The building only stayed in Hyde Park for five months but it was to exist for eighty four more years in another location across town.  There, it probably outlived everyone that ventured through it in 1851.  Once it was moved to a more prepared location the Crystal Palace (a nickname coined by a newspaperman) would acquire two more transepts, additional wings and running fountains both inside and out.

_ The photo above is dated 1854.  Photography was very much in its infancy at that time.  Daguerreotypes had been around since 1839 but the collodion process wasn’t announced or published until March 1851.  This image (by Philip Henry Delamotte) could be from an Ambrotype (a positive image on glass).  The American Civil War photographer Mathew Brady studied his craft in Europe and actually displayed some of his portraits at the Great Exhibition in 1851.

        

_ There were two new water towers built at the new location, only the one at the South end of the Palace is seen here, above left.  Impressive in their own right from an engineering perspective, at 280ft tall the towers were not quite as tall as the Statue of Liberty and its large pedestal combined.  A painting of a Royal Navy ceremony-dated 1917 is the center thumbnail.  The third picture is of a naval gun, dated between 1920 – 1924.

_ These last photographs are presented as thumbnails mainly because they are bandwidth hoggish and would slow down the web-page otherwise.  The first photo below shows the Central and North transepts, the North water tower and North wing – which normally held new agricultural and industrial implements on display.  This excellent picture must have been made before 1866 because that’s the year that the North transept caught fire and burned up.  In 1871 the world’s largest saltwater aquarium took its place.  In the next photograph the North transept is clearly missing.  This aerial photo had to have been taken sometime before 1936 because that is the year when the whole Crystal Palace was destroyed by fire.  The two water towers survived the fire but were deliberately destroyed shortly later in WWII to deny German bomber pilots a visual fix from such an established landmark.

_ Over its eight decade long lifespan the Crystal Palace attracted and hosted a broad assortment of eccentric and eclectic attractions. Year after year it hosted performances, concerts and public festivals.  In this doctored photograph below, taken somewhere between 1887 and 1889, some blocks of about 100 people are colored in. This particular photo is said to show a Handel Festival taking place at one end of the big central transept. The Grand Orchestra of about 4,000 musicians surrounded the organ.  The Great Organ in the back of the photo had 4,500 pipes, some obviously out of sight.  There was only enough room left to seat 4,000 spectators in the audience.  One wonders what these orchestras sounded like.  Did they produce magnificent awe-inspiring sounds or did this many musicians produce a very loud cacophony?

  Between the Great Exhibition (1851) and the “Centennial Exposition” in Philadelphia (1876) there were four other World Expos (in Paris, London, Paris and Vienna respectfully).

  For the 1876 fair in Philadelphia’s Fairmount Park, some 200 buildings were erected, but now only four remain.   The “Main Exhibition Building” became the world’s largest building (in area), by enclosing 21.5 acres of space.  Its construction incorporated prefabricated sub-assemblies and it was disassembled in 1881.  Another temporary building erected for the same exhibition was the 558,440 sq. ft. “Machinery Hall”.

  Another building built for the expo was expected to be permanent however.  The 73,191 sq. ft. “Horticultural Hall” was built to resemble architecturally – the twenty-five year old Crystal Palace in London.  However a hurricane tore the building apart in 1954 so its remainder was demolished.  Another Horticulture Center was built on the site in 1976.  Two etchings with slight differences, from the same vantage point, are shown below.

Hot Stuff 3 – Rocket stoves to meat smoking

Pertinent

394d

Versions of the “rocket stove” principle have been manufactured for about 90 years, so the concept must be older.  Above is a cheap and quick example of a rocket stove made with about seven tin cans.  The barrier between the inside chimney of small cans and the outside layer of large ones, is insulated with sifted wood ashes.  Rocket stoves are efficient for cooking because they burn hot and use very little fuel.  The “rocket” name undoubtedly stems from the vigorous manner in which air, flame and smoke are all drawn into the chimney.

U1l

For free standing little cook stoves and water heaters the optimum chimney height might be a little less than three times whatever inside diameter is actually chosen for the chimney.   These proportions seem to engender the best draft.

Once a fire has been ignited it takes a few minutes for the stove to become normalized.  Once hot and working correctly these little stoves consume almost all the volatiles in smoke and leave little pollution.   Using just dry twigs these stoves are capable of reaching 1,600 – 1,700°F (926°C).    * That’s a temp high enough to melt tin, lead, zinc, antimony, magnesium, aluminum and lava – but not silver, gold or copper.

Iron stoves or the ‘tinplate’ steel found in a soup can will not stand up to long term heat of this degree because of the accelerated rate of oxidization.   For this reason a stainless steel, ceramic or refractory version would be desirable for stove longevity.

cBlock-3e

Slick stoves working upon the rocket principle have been made with cinder blocks and stacked bricks.  This link is to a rocket stove manufactured in China.  These are practical products but seem a bit costly.

bucket_form5c

A long lasting cementatious rocket stove can easily be made at home.   This image (idea robbed from a video) depicts creating a mold from plastic sewer pie and a 5 gallon plastic bucket.   Yes the mold could be filled with plain cement but a refractory mix would be more desirable.   A concrete rocket stove would conduct heat and become hot to the touch and would also be heavy to move.   A stove cast of proper refractory would be lighter weight and insulated, allowing desirable higher heat inside the chimney.

Opinions and examples of refractory mixes vary widely.   Perlite and vermiculite are frequently listed as light weight insulating ingredients in refractory mixes.  If the intended function is not too demanding, wood sawdust or peat moss might substitute as the light weight, insulating ingredient.  Perlite is a volcanic glass that has been ‘puffed up’ like popcorn (with the help of escaping steam when it was created).   You’ll frequently find little individual white beads of perlite mixed in with commercial potting soils, or sold in bulk at plant nurseries as a soil amendment.  Exfoliated vermiculite possesses many of the same qualities as perlite.   Fireclay is an ingredient used in the refractory of brick, ceramic and glass kilns, because few other building materials can repeatedly withstand such high working temperatures.   An easy to remember recipe for an adequate refractory mixture would be four equal parts each of sand, Portland cement, fireclay and perlite (or vermiculite).  Those proportions could be tweaked a bit to reduce sand and cement (1.5 sand, 1.5 cement, 2 fireclay, 2 perlite).

When casting a mixture like this it is important to use as little water as feasible to ensure the strength of the concrete (refractory).  Do not forget to allow adequate space at the bottom for insulation of the chimney and remember to tamp this first, with a stick, before filling the remainder of the mold.   A wire skeleton or armature of some sort would greatly enhance the long term resilience of such a cast.

kettle-m

Two centuries or more ago, the chimney in the center principle was being exploited by expensive handmade self heating teapots known as samovars.   Manufactured portable utensils for heating or sanitizing water outdoors began to be seen in numbers for the first time however during WWII, when the New Zealand Army issued their soldiers with mess kits containing jacketed kettles.   ‘Storm kettles’ or ‘volcano kettles’ work well in windy or rainy weather.  Fuel from twigs to straw to buffalo chips can be found almost anywhere and cost nothing.

Not commonly found in American sporting goods stores, these kettles are made by several little companies and are produced in either aluminum or stainless steel versions.   Rather than pack into the woods a stove that requires special fuel (sterno, denatured alcohol, hexamine tablets, paraffin wax, kerosene or  naphtha (white gas)) it seems more logical to carry one that simply uses fuel which can be picked up from the ground.

For some time now some people have been using a larger form of the rocket stove, known as a “mass heater”, to warm the home.  In this case the exhaust from the chimney is captured and turned downward, then circulated through a wall, the floor or a banco (bench).   The masonry in the wall, floor or bench acts as a thermal mass or heat sink that collects the heat and releases it slowly.  So from the illustration above an oil drum or other metal hood accomplishes the first heat exchange to the room’s atmosphere.  Any remaining heat is ideally captured by a thermal mass before the exhaust is finally released to the outdoors.

A few examples of these thermal mass heaters are found almost all over the world.  It would be very feasible to pre-heat water for the home by wrapping a water line around a rocket stove’s chimney.   Potential construction concerns for building a mass heater of this type include ensuring that the draw of the stove is sufficient to push exhaust through a long ductwork.  One critical dimension is the distance between the top of the chimney and the hood (drum).   Some people brag that the amount of firewood needed to warm their house was reduced by 75% after resorting to a ‘mass heater’.   One should consider however the extra time spent splitting wood into pieces small enough to feed into this stove, and the extra attention probably required to keep the (fast burning) stove continually fed.   Depending on size it may take several hours to several days to equalize the thermal mass, so hopefully in the meantime the house would be equipped with an auxiliary source of heat.

 

Added 7/27/2016

The rocket stove mass heater takes its idea from the much older masonry stoves and or ceramic stoves of Europe and Russia.  Usually constructed of brick and covered in tile these often massive heating appliances are at least one thousand years old in design principle yet are still “greener” and more efficient than modern heating alternatives. 

The typical “tulikivi” (Finnish), “kachelöfen” (German), “kakelugn” (Swedish) or “pechka” (Russian) oven stoves only need to be fired about twice a day to provide a continuous 24 hour heat.  In some homes the people sleep on them, or may also bake with them.   When designed well they burn very hot and therefore leave little creosote buildup behind.   Inside the fire’s exhaust must furl around a labyrinth of baffles before it can escape, providing time and surface area for energy transfer.

STOVE5c

In the last century or so of newer building construction, massive masonry heaters like these were usually replaced with much smaller coal, oil or natural gas burning alternatives.   

The cast iron wood cookstove became a favored house heating appliance in America homes between the 1870s and the 1920s.  They were advertised in newspapers and mail order catalogues and were manufactured by a host of different companies like ACME, Acorn, Garland, Majestic, Monarch, Peninsular, Pilgrim and Sterling.  These wood stoves or ranges could act as energy centers perhaps for the whole house and they supposedly baked a better loaf of bread than any modern gas or electrical counterpart.   Different models came with different options including ornate chrome (probably nickel) trim, hot water reservoirs, foot latch, thermometers, broiler drawers and secondary warming chambers.   Cooking on such a stove could require much patience to establish the fire, because in addition to the firebox some models came with an adjustable main draft regulator, check draft regulator, stove pipe damper and an auxiliary damper.  It was standard practice for a housewife to keep a stock pot on the back of the stove, where she put leftover scraps of meat and bone.   Comfortable and desirable in the winter – these stoves could become beast to cook with however on hot summer days.

After reconsideration the project on the right above will be redesigned from an “L” shape to a “J” shape, to allow fuel to be fed from the vertical axis.   Sheet metal screws will be reversed so that they can be removed from the inside.  After that cans are to be wrapped in plastic food wrap and a chicken wire armature will be wrapped around the cans – suspended about an inch away.   After that a refractory mix will be slathered over the armature to a depth of about 2 inches.    Some of the metal cans will be too hard to remove initially, until years afterwards when the rust can then be pulled from the refractory easily.

The image above is a little incongruous with the topic of rocket stoves, but since it is related to fire and cooking and was available, it is included now.  Methods for cold meat smoking are diverse and numerous.  This image depicts a homemade variation of a commercial product which blows a steady stream of wood smoke into a meat holding chamber.   The main feature is the venturi which in this case is powered by a tiny air pump (like one used to aerate a fish aquarium).  The can below the homemade copper venturi needs a lid that will open and close; to insert wood chips or remove ashes.  The can needs some holes in its bottom so that combustion air can be drawn up through the smoldering woodchips.  Twelve to sixteen ounces of (hardwood) wood chips should provide about three hours of smoke.

There is not enough time and space left in this installment to adequately explain the important details of meat curing.   Remember that the wealthier half of civilization has only possessed artificial refrigeration for the last century or less.   Salt and smoke dehydrate -bloody raw meat.  Salt and smoke and cold weather have historically been the preferred tools for preserving meat by protecting it from bacterial spoilage.  Traditionally, smokehouses worked continually around the clock and pretty much throughout the year.  It is recognized by some that today’s commercial hams and bacons will putrefy long before they should (had they been properly cured and smoked by traditional methods rather than by quick methods).

In 1832 it was discovered that pyroligneous acid from creosote in wood smoke was the antiseptic preservative which protected meat.  Today commercial meat processors commonly inject into boned meat, salt, nitrites, nitrates and sulfides.  Before slaughter the animal may have been fed antibiotics, steroids or additives like ractopamine hydrochlorid.  About 70% of all chicken and beef sold in the U.S. and Canada is actually treated with carbon monoxide before you buy it.   The best way to tenderize meat without resorting to chemicals, is to cook it slowly.  Nowadays the best reason for treating meat to wood smoke (longer is better) is for the taste.

The blank sheet

The theme of this post is to display or to briefly discuss the compaction of information into one composite image or upon one blank sheet of paper.   A book filled with singular pages of compacted but understandable and usable information would be unique indeed.   The old adage that “a picture is worth a thousand words” occasionally bellows with indisputable truth.   Few complex ideas can be adequately or succinctly represented in a singular page however, nor can a cohesive theme be carried very far in such a manner.   The support of an image by language, sometimes excessive language is often needed to transfer an idea adequately.   The target audience is an important consideration.   It is hard to imagine holding the attention of  future generations of readers for long when book pages look like they came from Encyclopedia Britannica.   After 244 years of publication this venerable encyclopedia is no longer being printed.  Indeed, the future viability of the printed book itself is presently being been called into question.

In the next two examples to follow, an attempt was made to cram the ‘Gestalt’ of one idea onto one page.  The importance of a ladder or of a sawhorse is minor and incidental  to this exercise in terseness.   While pictures can be important, one cannot hope to make a meaningful textbook from just pictures.  Fiction writing and non-fiction writing are fields very far apart.   It seems possible however that brevity of language even in a textbook could be a desirable and achievable goal.   As Ernest Hemingway or Winston Churchill might have agreed; simple words and terse language are often best.  A few of the later pictures to follow contain enough information to stand with minimal text support.  Other auxiliary images presented here just support a given subject and are not germane to the topic of minimalism.   All of the following thumbnails can be enlarged.

ladder_d

The composite image above conveys the construction of a stable and strong homemade ladder that can be made for $5 or $6 worth of material.  It will last for many years if not abused.   The whole concept is presented or published here within one page.

A larger and better version of this low resolution image of a sawhorse plan, should be available <here> (if Google Docs and browser combination permits the 1.65 Mb download).   Before the late 1950’s – early 60’s, construction “blueprints” predominately had dark indigo blue backgrounds with white line drawings and text.   Large ammonia printers were used to develop prints on large sheets of paper, where the cellulose film had a black background except where the datum allowed the light to pass through.  This process was reversed during the 60’s and today we have “blueprints” with predominately white backgrounds and blue line drawings.   * The original security settings of the complete PDF document were set to test the anti printing PDF settings, not to affect any sort of copyright.

Above is an image of a 3v (third frequency) icosahedron based geodesic dome.  This dome is a 5/8ths representation of a complete geosphere.   In this image several pieces of information are simultaneously presented.   The organization and assembly of struts can be deciphered.   An opening big enough to drive a vehicle through can be made by removing a few struts, but importantly those removed struts can be put back to good use.   Finally a feeling for the size of this two story dome is transferred by the addition of the humanoid scribble.   That humanoid works for the relative size of the opening but in this position and perspective makes the rest of the dome look a bit small.  Some of these next  images are of lesser importance but support discussion in the short chapter on domes in my book.

platonic

There are only five regular, convex polyhedrons (above) and these are called the Platonic solids.   Any can be chosen for the calculation of a geodesic dome but the icosahedron is the most popular.

This image above illustrates that the frequency of an icosahedron based dome can be quickly determined by finding the pentagons and counting the segments between centers.

Above: A represents the primary 20 sided icosahedron, B is a cardboard model (a 3/4 geodesic with 15 sides or faces) and C is simply an equilateral triangular face from either A or B.   This example is called a 1v, single or first frequency geodesic.

This is an intermediate and modified image from a photograph of a cardboard model held together with tape.

Above the image displays that geodesics can be bent and twisted into many shapes.  These sketches represent structures that already exist in the real world.  The carport shaped cover in the center is not a geodesic.

These next three images address the less rigid but simpler to construct trapezium dome.   After reading a short explanation any builder worth his or her salt would be capable of easily exploiting the concept.   Only 4 factors are required to compute all the strut lengths or rafters of a trapezium and there is no need to memorize those factors if a copy of this image is handy.

tz3b2

The image below displays the practicality of interfacing trapezium sections to the straight and square lines of an existing building.

trapaz4

The following images comes not from the chapter on domes but from another chapter on knots and nets.   Round parachutes are typically constructed with suspension lines forming the skeleton of the canopy that closely resemble the structure of a trapezium.   Making a rope net based on the trapezium would be very useful to hold down square tarpaulins that might be spread over a geodesic dome infrastructure.   From the image; it is simplest to tie one quadrant of such a net at a time.  The same trapezium strut factors are displayed as well as visual suggestions as to where to tie cross cordage in an efficient manner.

netb11b

Some survival books and Army field manuals explain how to construct a net that is composed mostly of simple overhand knots.  This image alone without supporting text is probably sufficient to transfer the whole idea.

These final three image constructions simplify and transport the basic skill required for tying a fisherman’s net.

*Added April 2015

When a request for a simple garden canopy design was recently made, the trapezium truss idea was one that came to mind. A previous drawing was quickly dissected and turned around for an idea to create a frame which would hold up shade screens or plastic tarpaulins. The idea could be expanded upon to create a pool awning or temporary carport. This idea differs slightly from the Nissen huts of WWI & Quonset huts of WWII.
