7 Beau de Rochas, Alphonse Eugène
SUBJECT AREA: Steam and internal combustion engines[br]b. 1815 Franced. 1893 France[br]French railway engineer, patentee of a four-stroke cycle engine.[br]Renowned more for his ideas on technical matters than his practical deeds, Beau de Rochas was a prolific thinker. Within a few years he proposed a rail tunnel beneath the English Channel, a submarine telegraph, a new kind of drive for canal boats, the use of steel for high-pressure boilers and a method of improving the adhesion of locomotive wheels travelling the Alps.The most notable of Beau de Rochas's ideas occurred in 1862 when he was employed as Ingenieur Attaché to the Central de Chemins. With remarkable foresight, he expressed the theoretical considerations for the cycle of operations for the now widely used four-stroke cycle engine. A French patent of 1862 lapsed with a failure to pay the annuity and thus the proposals for a new motive power lapsed into obscurity. Resurrected some twenty years later, the Beau de Rochas tract figures prominently in patent litigation cases. In 1885, a German court upheld a submission by a German patent lawyer that Otto's four-stroke engine of 1876 infringed the Beau de Rochas patent. It remains a mystery why Beau de Rochas never emerged at any time to defend his claims. In France he is regarded as the inventor of the four-stroke cycle engine.[br]Principal Honours and DistinctionsSociété d'Encouragement pour l'Industrie Nationale, prize of 3000 francs, 1891.Bibliography1885, The Engineer 60:441 (an English translation of the Beau de Rochas tract).Further Reading1938, Bulletin de la Société d'Encouragement pour l'Industrie Nationale 137:209–39. 1962, Document pour l'histoire des techniques Cahier no. 2: pp. 3–42.B.Donkin, 1900, The Gas, Oil and Air Engine, London: p. 467.See also: Langen, EugenKABBiographical history of technology > Beau de Rochas, Alphonse Eugène

8 Smith, Sir Francis Pettit
SUBJECT AREA: Ports and shipping[br]b. 9 February 1808 Copperhurst Farm, near Hythe, Kent, Englandd. 12 February 1874 South Kensington, London, England[br]English inventor of the screw propeller.[br]Smith was the only son of Charles Smith, Postmaster at Hythe, and his wife Sarah (née Pettit). After education at a private school in Ashford, Kent, he took to farming, first on Romney Marsh, then at Hendon, Middlesex. As a boy, he showed much skill in the construction of model boats, especially in devising their means of propulsion. He maintained this interest into adult life and in 1835 he made a model propelled by a screw driven by a spring. This worked so well that he became convinced that the screw propeller offered a better method of propulsion than the paddle wheels that were then in general use. This notion so fired his enthusiasm that he virtually gave up farming to devote himself to perfecting his invention. The following year he produced a better model, which he successfully demonstrated to friends on his farm at Hendon and afterwards to the public at the Adelaide Gallery in London. On 31 May 1836 Smith was granted a patent for the propulsion of vessels by means of a screw.The idea of screw propulsion was not new, however, for it had been mooted as early as the seventeenth century and since then several proposals had been advanced, but without successful practical application. Indeed, simultaneously but quite independently of Smith, the Swedish engineer John Ericsson had invented the ship's propeller and obtained a patent on 13 July 1836, just weeks after Smith. But Smith was completely unaware of this and pursued his own device in the belief that he was the sole inventor.With some financial and technical backing, Smith was able to construct a 10 ton boat driven by a screw and powered by a steam engine of about 6 hp (4.5 kW). After showing it off to the public, Smith tried it out at sea, from Ramsgate round to Dover and Hythe, returning in stormy weather. The screw performed well in both calm and rough water. The engineering world seemed opposed to the new method of propulsion, but the Admiralty gave cautious encouragement in 1839 by ordering that the 237 ton Archimedes be equipped with a screw. It showed itself superior to the Vulcan, one of the fastest paddle-driven ships in the Navy. The ship was put through its paces in several ports, including Bristol, where Isambard Kingdom Brunel was constructing his Great Britain, the first large iron ocean-going vessel. Brunel was so impressed that he adapted his ship for screw propulsion.Meanwhile, in spite of favourable reports, the Admiralty were dragging their feet and ordered further trials, fitting Smith's four-bladed propeller to the Rattler, then under construction and completed in 1844. The trials were a complete success and propelled their lordships of the Admiralty to a decision to equip twenty ships with screw propulsion, under Smith's supervision.At last the superiority of screw propulsion was generally accepted and virtually universally adopted. Yet Smith gained little financial reward for his invention and in 1850 he retired to Guernsey to resume his farming life. In 1860 financial pressures compelled him to accept the position of Curator of Patent Models at the Patent Museum in South Kensington, London, a post he held until his death. Belated recognition by the Government, then headed by Lord Palmerston, came in 1855 with the grant of an annual pension of £200. Two years later Smith received unofficial recognition when he was presented with a national testimonial, consisting of a service of plate and nearly £3,000 in cash subscribed largely by the shipbuilding and engineering community. Finally, in 1871 Smith was honoured with a knighthood.[br]Principal Honours and DistinctionsKnighted 1871.Further ReadingObituary, 1874, Illustrated London News (7 February).1856, On the Invention and Progress of the Screw Propeller, London (provides biographical details).Smith and his invention are referred to in papers in Transactions of the Newcomen Society, 14 (1934): 9; 19 (1939): 145–8, 155–7, 161–4, 237–9.LRDBiographical history of technology > Smith, Sir Francis Pettit

12 Lenoir, Jean Joseph Etienne
SUBJECT AREA: Metallurgy, Railways and locomotives, Steam and internal combustion engines, Telecommunications[br]b. 1822 Mussey-la-Ville, Belgiumd. 1900 Verenna Saint-Hildar, France[br]Belgian (naturalized French in 1870) inventor of internal combustion engines, an electroplating process and railway telegraphy systems.[br]Leaving his native village for Paris at the age of 16, Lenoir became a metal enameller. Experiments with various electroplating processes provided a useful knowledge of electricity that showed in many of his later ideas. Electric ignition, although somewhat unreliable, was a feature of the Lenoir gas engine which appeared in 1860. Resembling the steam engine of the day, Lenoir engines used a non-compression cycle of operations, in which the gas-air mixture of about atmospheric pressure was being ignited at one-third of the induction stroke. The engines were double acting. About five hundred of Lenoir's engines were built, mostly in Paris by M.Hippolyte Marinoni and by Lefébvre; the Reading Ironworks in England built about one hundred. Many useful applications of the engine are recorded, but the explosive shock that occurred on ignition, together with the unreliable ignition systems, prevented large-scale acceptance of the engine in industry. However, Lenoir's effort and achievements stimulated much discussion, and N.A. Otto is reported to have carried out his first experiments on a Lenoir engine.[br]Principal Honours and DistinctionsAcadémie des Sciences Prix Montyon Prize 1870.

13 Lumière, Auguste
SUBJECT AREA: Photography, film and optics[br]b. 19 October 1862 Besançon, Franced. 10 April 1954 Lyon, France[br]French scientist and inventor.[br]Auguste and his brother Louis Lumière (b. 5 October 1864 Besançon, France; d. 6 June 1948 Bandol, France) developed the photographic plate-making business founded by their father, Charles Antoine Lumière, at Lyons, extending production to roll-film manufacture in 1887. In the summer of 1894 their father brought to the factory a piece of Edison kinetoscope film, and said that they should produce films for the French owners of the new moving-picture machine. To do this, of course, a camera was needed; Louis was chiefly responsible for the design, which used an intermittent claw for driving the film, inspired by a sewing-machine mechanism. The machine was patented on 13 February 1895, and it was shown on 22 March 1895 at the Société d'Encouragement pour l'In-dustrie Nationale in Paris, with a projected film showing workers leaving the Lyons factory. Further demonstrations followed at the Sorbonne, and in Lyons during the Congrès des Sociétés de Photographie in June 1895. The Lumières filmed the delegates returning from an excursion, and showed the film to the Congrès the next day. To bring the Cinématographe, as it was called, to the public, the basement of the Grand Café in the Boulevard des Capuchines in Paris was rented, and on Saturday 28 December 1895 the first regular presentations of projected pictures to a paying public took place. The half-hour shows were an immediate success, and in a few months Lumière Cinématographes were seen throughout the world.The other principal area of achievement by the Lumière brothers was colour photography. They took up Lippman's method of interference colour photography, developing special grainless emulsions, and early in 1893 demonstrated their results by lighting them with an arc lamp and projecting them on to a screen. In 1895 they patented a method of subtractive colour photography involving printing the colour separations on bichromated gelatine glue sheets, which were then dyed and assembled in register, on paper for prints or bound between glass for transparencies. Their most successful colour process was based upon the colour-mosaic principle. In 1904 they described a process in which microscopic grains of potato starch, dyed red, green and blue, were scattered on a freshly varnished glass plate. When dried the mosaic was coated with varnish and then with a panchromatic emulsion. The plate was exposed with the mosaic towards the lens, and after reversal processing a colour transparency was produced. The process was launched commercially in 1907 under the name Autochrome; it was the first fully practical single-plate colour process to reach the public, remaining on the market until the 1930s, when it was followed by a film version using the same principle.Auguste and Louis received the Progress Medal of the Royal Photographic Society in 1909 for their work in colour photography. Auguste was also much involved in biological science and, having founded the Clinique Auguste Lumière, spent many of his later years working in the physiological laboratory.[br]Further ReadingGuy Borgé, 1980, Prestige de la photographie, Nos. 8, 9 and 10, Paris.

14 Planté, Raimond Louis Gaston
SUBJECT AREA: Electricity[br]b. 22 April 1834 Orthez, Franced. 21 May 1889 Paris, France[br]French physicist and inventor of a secondary electric cell from which was developed the widely used lead-acid storage battery.[br]After a scientific training at the Conservatoire des Arts et Métiers, Planté obtained an appointment as a Laboratory Assistant to Becquerel. Later, when he was employed as a chemist in the Parisian electroplating firm of Christofle et Cie, he carried out investigations into polarization in electrical cells, which led to his discovery of the lead-acid accumulator in 1859. This cell, with lead plates in an electrolyte of dilute sulphuric acid, had the characteristics of a storage device for electrical energy. Its performance was improved considerably if it was repeatedly charged and discharged, the active material being formed electrochemically from the lead of the plate itself. At the time of its discovery the Planté cell had little practical application and it was not until satisfactory dynamos were introduced that its commercial exploitation was possible. The cell was improved by Faure and later by Swan and others. The lead-acid cell became considerably important in the early days of electricity supply and later for electric traction and automobile use. The results of Planté's researches were communicated to the Academy of Sciences and published in various scientific periodicals. He devoted the last few years of his life to the study of atmospheric electricity.[br]Principal Honours and DistinctionsChevalier de la Légion d'honneur 1881.

15 Polhem, Christopher
SUBJECT AREA: Mining and extraction technology[br]b. 18 December 1661 Tingstade, Gotland, Sweden d. 1751[br]Swedish engineer and inventor.[br]He was the eldest son of Wolf Christopher Polhamma, a merchant. The father died in 1669 and the son was sent by his stepfather to an uncle in Stockholm who found him a place in the Deutsche Rechenschule. After the death of his uncle, he was forced to find employment, which he did with the Biorenklou family near Uppsala where he eventually became a kind of estate bailiff. It was during this period that he started to work with a lathe, a forge and at carpentry, displaying great technical ability. He realized that without further education he had little chance of making anything of his life, and accordingly, in 1687, he registered at the University of Uppsala where he studied astronomy and mathematics, remaining there for three years. He also repaired two astronomical pendulum clocks as well as the decrepit medieval clock in the cathedral. After a year's work he had this clock running properly: this was his breakthrough. He was summoned to Stockholm where the King awarded him a salary of 500 dalers a year as an encouragement to further efforts. Around this time, one of increasing mechanization and when mining was Sweden's principal industry, Pohlem made a model of a hoist frame for mines and the Mines Authority encouraged him to develop his ideas. In 1693 Polhem completed the Blankstot hoist at the Stora Kopparberg mine, which attracted great interest on the European continent.From 1694 to 1696 Polhem toured factories, mills and mines abroad in Germany, Holland, England and France, studying machinery of all kinds and meeting many foreign engineers. In 1698 he was appointed Director of Mining Engineering in Sweden, and in 1700 he became Master of Construction in the Falu Mine. He installed the Karl XII hoist there, powered by moving beams from a distant water-wheel. His plan of 1697 for all the machinery at the Falu mine to be driven by three large and remote water-wheels was never completed.In 1707 he was invited by the Elector of Hanover to visit the mines in the Harz district, where he successfully explained many of his ideas which were adopted by the local engineers. In 1700, in conjunction with Gabriel Stierncrona, he founded the Stiersunds Bruk at Husby in Southern Dalarna, a factory for the mass production of metal goods in iron, steel and bronze. Simple articles such as pans, trays, bowls, knives, scissors and mirrors were made there, together with the more sophisticated Polhem lock and the Stiersunds clock. Production was based on water power. Gear cutting for the clocks, shaping hammers for plates, file cutting and many other operations were all water powered, as was a roller mill for the sheet metal used in the factory. He also designed textile machinery such as stocking looms and spinning frames and machines for the manufacture of ribbons and other things.In many of his ideas Polhem was in advance of his time and Swedish country society was unable to absorb them. This was largely the reason for the Stiersund project being only a partial success. Polhem, too, was of a disputatious nature, self-opinionated almost to the point of conceit. He was a prolific writer, leaving over 20,000 pages of manuscript notes, drafts, essays on a wide range of subjects, which included building, brick-making, barrels, wheel-making, bell-casting, organ-building, methods of stopping a horse from bolting and a curious tap "to prevent serving maids from sneaking wine from the cask", the construction of ploughs and threshing machines. His major work, Kort Berattelse om de Fornamsta Mechaniska Inventioner (A Brief Account of the Most Famous Inventions), was printed in 1729 and is the main source of knowledge about his technological work. He is also known for his "mechanical alphabet", a collection of some eighty wooden models of mechanisms for educational purposes. It is in the National Museum of Science and Technology in Stockholm.[br]Bibliography1729, Kort Berattelse om de Fornamsta Mechaniska Inventioner (A Brief Account of the Most Famous Inventions).Further Reading1985, Christopher Polhem, 1661–1751, TheSwedish Daedalus' (catalogue of a travelling exhibition from the Swedish Institute in association with the National Museum of Science and Technology), Stockholm.IMcN -
16 Sellers, William
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 19 September 1824 Upper Darby, Pennsylvania, USAd. 24 January 1905 Philadelphia, Pennsylvania, USA[br]American mechanical engineer and inventor.[br]William Sellers was educated at a private school that had been established by his father and other relatives for their children, and at the age of 14 he was apprenticed for seven years to the machinist's trade with his uncle. At the end of his apprenticeship in 1845 he took charge of the machine shop of Fairbanks, Bancroft \& Co. in Providence, Rhode Island. In 1848 he established his own factory manufacturing machine tools and mill gearing in Philadelphia, where he was soon joined by Edward Bancroft, the firm becoming Bancroft \& Sellers. After Bancroft's death the name was changed in 1856 to William Sellers \& Co. and Sellers served as President until the end of his life. His machine tools were characterized by their robust construction and absence of decorative embellishments. In 1868 he formed the Edgemoor Iron Company, of which he was President. This company supplied the structural ironwork for the Centennial Exhibition buildings and much of the material for the Brooklyn Bridge. In 1873 he reorganized the William Butcher Steel Works, renaming it the Midvale Steel Company, and under his presidency it became a leader in the production of heavy ordnance. It was at the Midvale Steel Company that Frederick W. Taylor began, with the encouragement of Sellers, his experiments on cutting tools.In 1860 Sellers obtained the American rights of the patent for the Giffard injector for feeding steam boilers. He later invented his own improvements to the injector, which numbered among his many other patents, most of which related to machine tools. Probably Sellers's most important contribution to the engineering industry was his proposal for a system of screw threads made in 1864 and later adopted as the American national standard.Sellers was a founder member in 1880 of the American Society of Mechanical Engineers and was also a member of many other learned societies in America and other countries, including, in Britain, the Institution of Mechanical Engineers and the Iron and Steel Institute.[br]Principal Honours and DistinctionsChevalier de la Légion d'honneur 1889.
