History of steam road vehicles

History of steam road vehicles describes the development of vehicles powered by a steam engine for use on land; whether for conventional road use, such as the steam car and steam waggon, or for agricultural or heavy haulage work, such as the traction engine.The first experimental vehicles were built in the 17th and 18th century, but it was not until after Richard Trevithick had developed the use of high-pressure steam, around 1800, that mobile steam engines became a practical proposition. The first half of the 19th century saw great progress in steam vehicle design, and by the 1850s it was viable to produce them on a commercial basis. The next sixty years saw continuing improvements in vehicle technology and manufacturing techniques and steam road vehicles were used for many applications. In the twentieth century, the rapid development of internal combustion engine technology, coupled with adverse legislation, led to the demise of the steam engine as a source of propulsion of vehicles on a commercial basis, with relatively few remaining in use after the Second World War. However, many vehicles were acquired by enthusiasts for preservation, and numerous examples are still in existence. Moreover, the threat of Global Warming, and the search for renewable energy sources, has led to a resurgence of interest in utilising steam as a power source for road vehicles in the future.

Early pioneers

Early research on the steam engine before 1700 was closely linked to the quest for self-propelled vehicles and ships; the first practical applications from 1712 were stationary plant working at very low pressure which entailed engines of very large dimensions. The size reduction necessary for road transport meant an increase in steam pressure with all the attendant dangers, due to the inadequate boiler technology of the period. A strong opponent of high pressure steam was James Watt who, along with Matthew Boulton did all he could to dissuade William Murdoch from developing and patenting his steam carriage, built in model form in 1784.

Ferdinand Verbiest is suggested to have built what may have been the first steam powered car in about 1672, [cite web

During the latter part of the 18th century, there were numerous attempts to produce self-propelled steerable vehicles. Many remained in the form of models. Progress was dogged by many problems inherent to road vehicles in general, such as suitable power-plant giving steady rotative motion, suspension, braking, steering, adequate road surfaces, tyres, and vibration-resistant bodywork, among other issues. The extreme complexity of these issues can be said to have hampered progress over more than a hundred years, as much as hostile legislation.

Cugnot's "Fardier à vapeur"

Nicolas-Joseph Cugnot's "machine à feu pour le transport de wagons et surtout de l'artillerie" ("fire engine for transporting wagons and especially artillery") was built from 1769 in two versions for use by the French Army. Cugnot's "fardier", a term usually applied to a massive two-wheeled cart for exceptionally heavy loads, was intended to be capable of transporting 4 tonnes (3.9 tons), and of travelling at up to 4 km/h (2.5 mph). The vehicle was of tricycle layout, with two rear wheels and a steerable front wheel controlled by a tiller. There is considerable evidence from the period this vehicle actually ran, making it probably the first to do so; however it remained a short-lived experiment due to inherent instability and the vehicle's failure to meet the Army's specified performance level.

Trevithick's steam carriage

In 1801, Richard Trevithick constructed an experimental steam-driven vehicle ("Puffing Devil") which was equipped with a firebox enclosed within the boiler, with one vertical cylinder, the motion of the single piston being transmitted directly to the driving wheels by means of connecting rods. It was reported as weighing 1520 kg fully loaded, with a speed of 14.5 km/h (9 mph) on the flat. During its first trip it was left unattended and "self-destructed". Trevithick soon built the "London Steam Carriage" that ran successfully in London in 1803, but the venture failed to attract interest and soon folded up.

team-powered amphibious craft

In 1805 Oliver Evans built the "Oruktor Amphibolis" (literally 'amphibious digger'), a steam-powered, flat-bottomed dredger that he modified to be self-propelled on both land and water. It is widely believed to be the first amphibious vehicle, and the first steam-powered road vehicle to run in the United States. However, no designs for the machine survive, and the only accounts of its achievements come from Evans himself. Later analysis of Evans's descriptions suggests that the 5hp engine was unlikely to have been powerful enough to move the vehicle either on land or water, and that the chosen route for its demonstration would have had the benefit of gravity, river currents and tides to assist with the vehicles' progress. The dredger was not a success, and after a few years lying idle, was dismantled for parts.

Early steam carriage services

More commercially successful for a time than Trevithick's carriage were the steam carriage services operated in England in the 1830s, principally by Walter Hancock and associates of Sir Goldsworthy Gurney, among others. However, the heavy road tolls imposed by the Turnpike Acts discouraged steam road vehicles and for a short time allowed the continued monopoly of horse traction until railway trunk routes became established in the 1840s and '50s.

Victorian Age of Steam

Although engineers developed ingenious steam-powered road vehicles, they did not enjoy the same level of acceptance and expansion as steam power at sea and on the railways in the middle and late 19th century of the "Age of Steam".

Harsh legislation virtually eliminated mechanically propelled vehicles from the roads of Great Britain for 30 years, the "Locomotive Act" of 1861 imposing restrictive speed limits on "road locomotives" of 5 mph (8 km/h) in towns and cities, and 10 mph (16 km/h) in the country. In 1865 the "Locomotives Act" of that year (the famous Red Flag Act) further reduced the speed limits to 4 mph (6.4 km/h) in the country and just 2 mph (3.2 km/h) in towns and cities, additionally requiring a man bearing a red flag to precede every vehicle. At the same time, the act gave local authorities the power to specify the hours during which any such vehicle might use the roads. The sole exceptions were street trams which from 1879 onwards were authorised under licence from the Board of Trade.

In France the situation was radically different from the extent of the 1861 ministerial ruling formally authorising the circulation of steam vehicles on ordinary roads. Whilst this led to considerable technological advances throughout the 1870s and '80s, steam vehicles nevertheless remained a rarity.

To an extent competition from the successful railway network reduced the need for steam vehicles. From the 1860s onwards, attention was turned more to the development of various forms of traction engine which could either be used for stationary work such as sawing wood and threshing, or for transporting outsize loads too voluminous to go by rail. Steam trucks were also developed but their use was generally confined to the local distribution of heavy materials such as coal and building materials from railway stations and ports.

Thomas Rickett of Buckingham

Hence, in 1858, Thomas Rickett of Buckingham built the first of several steam carriages. Instead of looking like a carriage, it resembled a small locomotive. It consisted of a steam-engine mounted on three wheels: two large driven rear wheels and one smaller front wheel by which the vehicle was steered. The whole was driven by a chain drive and a maximum speed of twelve miles per hour was reached. The weight of the machine was 1.5 tonnes and somewhat lighter than Rickett's steam carriage.

Two years later, in 1860, Rickett built a similar but heavier vehicle. This model incorporated spur-gear drive instead of chain. In his final design, resembling a railway locomotive, the cylinders were coupled directly outside the cranks of the driving-axle.

H.P. Holt

H.P. Holt constructed a small road-steamer in 1866. Able to reach a speed of twenty miles per hour on level roads, it had a vertical boiler at the rear and two separate twin cylinder engines, each of which drove one rear wheel by means of a chain and sprocket wheels.

Catley and Ayres of York

In 1869, a small three wheeled vehicle propelled by a horizontal twin cylinder engine which drove the rear axle by spur-gearing; only one rear wheel was driven, the other turning freely on the axle. A vertical fire-tube boiler was mounted at the rear with a polished copper casing over the fire box and chimney; the boiler was enclosed in a mahogany casing. The front wheel was used for steering and the weight was only 19 cwt.

J.H. Knight of Farnham

1868 - 1870, John Henry Knight of Farnham built a four wheeled steam carriage which originally only had a single-cylinder engine.

R.W. Thomson of Aberdeen

1871, The road-steamer of R.W. Thomson of Aberdeen became famous because of wheels were shod with heavy solid rubber tyres.

Charles Randolph of Glasgow

1872, a steam-coach by Charles Randolph of Glasgow was convert|15|ft|m|0 in length, weighed four and a half tons, but had a maximum speed of only 6 miles per hour. Two vertical twin-cylinder engines where independent of one another and each drove one of the rear wheels by spur-gearing. The entire vehicle was enclosed and fitted with windows all around, carried six people, and even had two driving mirrors for observing traffic approaching from behind, the earliest recorded instance of such a device.

R. Neville Grenville of Glastonbury

In 1875, R. Neville Grenville of Glastonbury constructed a 3-wheeled steam vehicle which travelled a maximum of 15 miles per hour. This vehicle is still in existence, preserved in the Bristol City Museum.

Amédée Bollée

From 1873 to 1883 Amédée Bollée of Le Mans built a series of steam-powered passenger vehicles able to carry 6 to 12 people at speeds up to 60 km/h (38 mph), with such names as "Rapide" and "L'Obeissante". In his vehicles the boiler was mounted behind the passenger compartment with the engine at the front of the vehicle, driving the differential through a shaft with chain drive to the rear wheels. The driver sat behind the engine and steered by means of a wheel mounted on a vertical shaft. The lay-out more closely resembled much later motor cars than other steam vehicles.

Cederholm brothers

In 1892, painter Joens Cederholm and his brother, André, a blacksmith, designed their first car, a two-seater, introducing a condensor in 1894. It was not a success.Georgano, G.N. "Cars: Early and Vintage, 1886-1930". (London: Grange-Universal, 1985).]

De Dion & Bouton steam vehicles

:"See steam tricycle"The development by Serpollet of the flash steam boiler [Combe Jean-Marc & Escudier Bernard (1986, "L'Aventure scientifique et technique de la vapeur;" editions du CNRS, Paris, France; ISBN 2-222-03794-8] brought about the appearance of various diminutive steam tricycles and quadricycles during the late 80s and early 90s, notably by de Dion & Bouton; these successfully competed in long distance races but soon met with stiff competition for public favour from the internal combustion engine cars being developed, notably by Peugeot, that quickly cornered most of the popular market. In the face of the flood of IC cars, proponents of the steam car had to fight a long rear-guard battle that was to last into modern times.

Locomobile

This american firm bought the patents from the Stanley Brothers and began building their steam buggies from 1898 to 1905. Locomobile went into building gas cars andlasted until the Depression.

Early 20th century

In 1906 the Land Speed Record was broken by a Stanley steam car, piloted by Fred Marriot, which achieved 127 mph (203 km/h) at Ormond Beach, Florida. This annual week-long "Speed Week" was the forerunner of today's Daytona 500. This record was not exceeded until 1910, and has not been broken by a steam car since.

Doble Steam Car

Attempts were made to bring more advanced steam cars on the market, the most remarkable being the Doble Steam Car [Walton J.N. (1965-74) "Doble Steam Cars, Buses, Lorries, and Railcars" . "Light Steam Power" Isle of Man, UK.] which shortened start-up time very noticeably by incorporating a highly efficient monotube steam generator to heat a much smaller quantity of water along with effective automation of burner and water feed control. By 1923, Doble's steam cars could be started from cold with the turn of a key and driven off in 40 seconds or less.

Paxton Phoenix

Abner Doble developed the Doble Ultimax engine for the Paxton Phoenix steam car, built by the Paxton Engineering Division of McCulloch Motors Corporation, Los Angeles. Its sustained maximum power was Auto bhp|120|0. The project was eventually dropped in 1954. [ [http://content.cdlib.org/ark:/13030/kt1b69q0jt/?order=2&brand=calisphere "The True Story of the Paxton Phoenix."] "Road and Track", April 1957. pp. 13 - 18 ]

Decline of steam car development

Steam cars dropped-off in popularity following the adoption of the electric starter, which eliminated the need for risky hand cranking to start gasoline-powered cars. The introduction of assembly-line mass production by Henry Ford, which hugely reduced the cost of owning a conventional automobile, was also a strong factor in the steam car's demise as the Model T was both cheap and reliable.

Modern steam vehicles

Today most of these problems have been satisfactorily solved, but currently the re-introduction of any modern steam car project would run up against the problem of a general loss of steam engine culture which would make it difficult to set up an infrastructure of spares and qualified mechanics. It would also be necessary to meet more stringent safety standards and legislation than existed in the heyday of steam-powered road vehicles. The biggest arguments in favour of such a movement would be: greatly reduced pollution by particulates and noxious gases without recourse to filters, silence in operation, and direct drive without a gearbox. However the competition which development of a modern steam-powered vehicle has to consider is not so much from gasoline-powered cars as from electric, hydrogen-powered and hybrid vehicles.
