92 Albone, Daniel
[br]b. c.1860 Biggleswade, Bedfordshire, Englandd. 1906 England[br]English engineer who developed and manufactured the first commercially successful lightweight tractor.[br]The son of a market gardener, Albone's interest lay in mechanics, and by 1880 he had established his own business as a cycle maker and repairer. His inventive mind led to a number of patents relating to bicycle design, but his commercial success was particularly assisted by his achievements in cycle racing. From this early start he diversified his business, designing and supplying, amongst other things, axle bearings for the Great Northern Railway, and also building motor cycles and several cars. It is possible that he began working on tractors as early as 1896. Certainly by 1902 he had built his first prototype, to the three-wheeled design that was to remain in later production models. Weighing only 30 cwt, yet capable of pulling two binders or a two-furrow plough, Albone's Ivel tractor was ahead of anything in its time, and its power-to-weight ratio was to be unrivalled for almost a decade. Albone's commercial success was not entirely due to the mechanical tractor's superiority, but owed a considerable amount to his ability as a showman and demonstrator. He held two working demonstrations a month in the village of Biggleswade in Bedfordshire, where the tractors were made. The tractor was named after the river Ivel, which flowed through the village. The Ivel tractor gained twenty-six gold and silver medals at agricultural shows between 1902 and 1906, and was a significant contributor to Britain's position as the world's largest exporter of tractors between 1904 and 1914. Albone tried other forms of his tractor to increase its sales. He built a fire engine, and also an armoured vehicle, but failed to impress the War Office with its potential.Albone died at the age of 46. His tractor continued in production but remained essentially unimproved, and the company finally lost its sales to other designs, particularly those of American origin.[br]Further ReadingDetailed contemporary accounts of tractor development occur in the British periodical Implement and Machinery Review. Accounts of the Ivel appear in "The Trials of Agricultural Motors", Journal of the Royal Agricultural Society of England (1910), pp. 179–99. A series of general histories by Michael Williams have been published by Blandfords, of which Classic Farm Tractors (1984) includes an entry on the Ivel.AP -
93 Chapelon, André
[br]b. 26 October 1892 Saint-Paul-en-Cornillon, Loire, Franced. 29 June 1978 Paris, France[br]French locomotive engineer who developed high-performance steam locomotives.[br]Chapelon's technical education at the Ecole Centrale des Arts et Manufactures, Paris, was interrupted by extended military service during the First World War. From experience of observing artillery from the basket of a captive balloon, he developed a method of artillery fire control which was more accurate than that in use and which was adopted by the French army.In 1925 he joined the motive-power and rolling-stock department of the Paris-Orléans Railway under Chief Mechanical Engineer Maurice Lacoin and was given the task of improving the performance of its main-line 4–6–2 locomotives, most of them compounds. He had already made an intensive study of steam locomotive design and in 1926 introduced his Kylchap exhaust system, based in part on the earlier work of the Finnish engineer Kyläla. Chapelon improved the entrainment of the hot gases in the smokebox by the exhaust steam and so minimized back pressure in the cylinders, increasing the power of a locomotive substantially. He also greatly increased the cross-sectional area of steam passages, used poppet valves instead of piston valves and increased superheating of steam. PO (Paris-Orléans) 4–6–2s rebuilt on these principles from 1929 onwards proved able to haul 800-ton trains, in place of the previous 500-ton trains, and to do so to accelerated schedules with reduced coal consumption. Commencing in 1932, some were converted, at the time of rebuilding, into 4–8–0s to increase adhesive weight for hauling heavy trains over the steeply graded Paris-Toulouse line.Chapelon's principles were quickly adopted on other French railways and elsewhere.H.N. Gresley was particularly influenced by them. After formation of the French National Railways (SNCF) in 1938, Chapelon produced in 1941 a prototype rebuilt PO 2–10–0 freight locomotive as a six-cylinder compound, with four low-pressure cylinders to maximize expansive use of steam and with all cylinders steam-jacketed to minimize heat loss by condensation and radiation. War conditions delayed extended testing until 1948–52. Meanwhile Chapelon had, by rebuilding, produced in 1946 a high-powered, three-cylinder, compound 4–8–4 intended as a stage in development of a proposed range of powerful and thermally efficient steam locomotives for the postwar SNCF: a high-speed 4–6–4 in this range was to run at sustained speeds of 125 mph (200 km/h). However, plans for improved steam locomotives were then overtaken in France by electriflcation and dieselization, though the performance of the 4–8–4, which produced 4,000 hp (3,000 kW) at the drawbar for the first time in Europe, prompted modification of electric locomotives, already on order, to increase their power.Chapelon retired from the SNCF in 1953, but continued to act as a consultant. His principles were incorporated into steam locomotives built in France for export to South America, and even after the energy crisis of 1973 he was consulted on projects to build improved, high-powered steam locomotives for countries with reserves of cheap coal. The eventual fall in oil prices brought these to an end.[br]Bibliography1938, La Locomotive à vapeur, Paris: J.B.Bailière (a comprehensive summary of contemporary knowledge of every function of the locomotive).Further ReadingH.C.B.Rogers, 1972, Chapelon, Genius of French Steam, Shepperton: Ian Allan.1986, "André Chapelon, locomotive engineer: a survey of his work", Transactions of the Newcomen Society 58 (a symposium on Chapelon's work).Obituary, 1978, Railway Engineer (September/October) (makes reference to the technical significance of Chapelon's work).PJGR -
94 Crælius, Per Anton
SUBJECT AREA: Mining and extraction technology[br]b. 2 November 1854 Stockholm, Swedend. 7 August 1905 Stockholm, Sweden[br]Swedish mining engineer, inventor of the core drilling technique for prospecting purposes.[br]Having completed his studies at the Technological Institute in Stockholm and the Mining School at Falun, Crælius was awarded a grant by the Swedish Jernkontoret and in 1879 he travelled to Germany, France and Belgium in order to study technological aspects of the mining, iron and steel industries. In the same year he went to the United States, where he worked with an iron works in Colorado and a mining company in Nevada. In 1884, having returned to Sweden, he obtained an appointment in the Norberg mines; two years later, he took up employment at the Ängelsberg oilmill.His mining experience had shown him the demand for a reliable, handy and cheap method of drilling, particularly for prospecting purposes. He had become acquainted with modern drilling methods in America, possibly including Albert Fauck's drilling jar. In 1886, Crælius designed his first small-diameter drill, which was assembled in one unit. Its rotating boring rod, smooth on the outside, was fixed inside a hollow mandrel which could be turned in any direction. This first drill was hand-driven, but the hydraulic version of it became the prototype for all near-surface prospecting drills in use worldwide in the late twentieth century.Between 1890 and 1900 Crælius was managing director of the Morgårdshammar mechanical workshops, where he was able to continue the development of his drilling apparatus. He successfully applied diesel engines in the 1890s, and in 1895 he added diamond crowns to the drill. The commercial exploitation of the invention was carried out by Svenska Diamantbergborrings AB, of which Crælius was a director from its establishment in 1886.[br]Further ReadingG.Glockemeier, 1913, Diamantbohrungen für Schürf-und Aufschlußarbeiten über und unter Tage, Berlin (examines the technological aspects of Crælius's drilling method).A.Nachmanson and K.Sundberg, 1936, Svenska Diamantbergborrings Aktiebolaget 1886–1936, Uppsala (outlines extensively the merits of Crælius's invention).See also: Fauvelle, Pierre-PascalWK -
95 Ferguson, Harry
SUBJECT AREA: Agricultural and food technology[br]b. 4 November 1884 County Down, Irelandd. 25 October 1960 England[br]Irish engineer who developed a tractor hydraulic system for cultivation equipment, and thereby revolutionized tractor design.[br]Ferguson's father was a small farmer who expected his son to help on the farm from an early age. As a result he received little formal education, and on leaving school joined his brother in a backstreet workshop in Belfast repairing motor bikes. By the age of 19 he had built his own bike and began hill-climbing competitions and racing. His successes in these ventures gained useful publicity for the workshop. In 1907 he built his own car and entered it into competitions, and in 1909 became the first person in Britain to build and fly a machine that was heavier than air.On the outbreak of the First World War he was appointed by the Irish Department of Agriculture to supervise the operation and maintenance of all farm tractors. His experiences convinced him that even the Ford tractor and the implements available for it were inadequate for the task, and he began to experiment with his own plough designs. The formation of the Ferguson-Sherman Corporation resulted in the production of thousands of the ploughs he had designed for the Ford tractor, but in 1928 Ford discontinued production of tractors, and Ferguson returned to Ireland. He immediately began to design his own tractor. Six years of development led to the building of a prototype that weighed only 16 cwt (813kg). In 1936 David Brown of Huddersfield, Yorkshire, began production of these tractors for Ferguson, but the partnership was not wholly successful and was dissolved after three years. In 1939 Ferguson and Ford reached their famous "Handshake agreement", in which no formal contract was signed, and the mass production of the Ford Ferguson system tractors began that year. During the next nine years 300,000 tractors and a million implements were produced under this agreement. However, on the death of Henry Ford the company began production, under his son, of their own tractor. Ferguson returned to the UK and negotiated a deal with the Standard Motor Company of Coventry for the production of his tractor. At the same time he took legal action against Ford, which resulted in that company being forced to stop production and to pay damages amounting to US$9.5 million.Aware that his equipment would only operate when set up properly, Ferguson established a training school at Stoneleigh in Warwickshire which was to be a model for other manufacturers. In 1953, by amicable agreement, Ferguson amalgamated with the Massey Harris Company to form Massey Ferguson, and in so doing added harvesting machinery to the range of equipment produced. A year later he disposed of his shares in the new company and turned his attention again to the motor car. Although a number of experimental cars were produced, there were no long-lasting developments from this venture other than a four-wheel-drive system based on hydraulics; this was used by a number of manufacturers on occasional models. Ferguson's death heralded the end of these developments.[br]Principal Honours and DistinctionsHonorary DSc Queen's University, Belfast, 1948.Further ReadingC.Murray, 1972, Harry Ferguson, Inventor and Pioneer.

96 Ohain, Hans Joachim Pabst von
SUBJECT AREA: Aerospace[br]b. 14 December 1911 Dessau, Germany[br]German engineer who designed the first jet engine to power an aeroplane successfully.[br]Von Ohain studied engineering at the University of Göttingen, where he carried out research on gas-turbine engines, and centrifugal compressors in particular. In 1935 he patented a design for a jet engine (in Britain, Frank Whittle patented his jet-engine design in 1930). Von Ohain was recruited by the Heinkel company in 1936 to develop an engine for a jet aircraft. Ernst Heinkel was impressed by von Ohain's ideas and gave the project a high priority. The first engine was bench tested in September 1937. A more powerful version was developed and tested in air, suspended beneath a Heinkel dive-bomber, during the spring of 1939. A new airframe was designed to house the revolutionary power plant and designated the Heinkel He 178. A short flight was made on 24 August 1939 and the first recognized flight on 27 August. This important achievement received only a lukewarm response from the German authorities. Von Ohain's turbojet engine had a centrifugal compressor and developed a thrust of 380 kg (837 lb). An improved, more powerful, engine was developed and installed in a new twin-engined fighter design, the He 280. This flew on 2 April 1941 but never progressed beyond the prototype stage. By this time two other German companies, BMW and Junkers, were constructing successful turbojets with axial compressors: luckily for the Allies, Hitler was reluctant to pour his hard-pressed resources into this new breed of jet fighters. After the war, von Ohain emigrated to the United States and worked for the Air Force there.[br]Bibliography1929, "The evolution and future of aeropropulsion system", The Jet Age. 40 Years of Jet Aviation, Washington, DC: National Air \& Space Museum, Smithsonian Institution.Further ReadingVon Ohain's work is described in many books covering the history of aviation, and aero engines in particular, for example: R.Schlaifer and S.D.Heron, 1950, Development of Aircraft Engines and fuels, Boston.

97 Page, Charles Grafton
[br]b. 25 January 1812 Salem, Massachusetts, USAd. 5 May 1868 Washington, DC, USA[br]American scientist and inventor of electric motors.[br]Page graduated from Harvard in 1832 and subsequently attended Boston Medical School. He began to practise in Salem and also engaged in experimental research in electricity, discovering the improvement effected by substituting bundles of iron wire for solid bars in induction coils. He also created a device which he termed a Dynamic Multiplier, the prototype of the auto-transformer. Following a period in medical practice in Virginia, in 1841 he became one of the first two principal examiners in the United States Patent Office. He also held the Chair of Chemistry and Pharmacy at Columbian College, later George Washington University, between 1844 and 1849.A prolific inventor, Page completed several large electric motors in which reciprocating action was converted to rotary motion, and invested an extravagant sum of public money in a foredoomed effort to develop a 10-ton electric locomotive powered by primary batteries. This was unsuccessfully demonstrated in April 1851 on the Washington-Baltimore railway and seriously damaged his reputation. Page approached Thomas Davenport with an offer of partnership, but Davenport refused.After leaving the Patent Office in 1852 he became a patentee himself and advocated the reform of the patent procedures. Page returned to the Patent Office in 1861, and later persuaded Congress to pass a special Act permitting him to patent the induction coil. This was the cause, after his death, of protracted and widely publicized litigation.[br]Bibliography1867, History of Induction: The American Claim to the Induction Coil and itsElectrostatic Developments, Washington, DC.Further ReadingR.C.Post, 1976, Physics, Patents and Politics, New York (a biography which treats Page as a focal point for studying the American patent system).——1976, "Stray sparks from the induction coil: the Volta prize and the Page patent", Proceedings of the Institute of Electrical Engineers 64: 1,279–86 (a short account).W.J.King, 1962, The Development of Electrical Technology in the 19th Century, Washington, DC: Smithsonian Institution, Paper 28.GW -
98 Pixii, Antoine Hippolyte
SUBJECT AREA: Electricity[br]b. 1808 Franced. 1835[br]French instrument maker who devised the first machine to incorporate the basic elements of a modern electric generator.[br]Mechanical devices to transform energy from a mechanical to an electrical form followed shortly after Faraday's discovery of induction. One of the earliest was Pixii's magneto generator. Pixii had been an instrument maker to Arago and Ampère for a number of years and his machine was first announced to the Academy of Sciences in Paris in September 1832. In this hand-driven generator a permanent magnet was rotated in close proximity to two coils on soft iron cores, producing an alternating current. Subsequently Pixii adapted to a larger version of his machine a "see-saw" switch or commutator devised by Ampère, in order to obtain a unidirectional current. The machine provided a current similar to that obtained with a chemical cell and was capable of decomposing water into oxygen and hydrogen. It was the prototype of many magneto-electric machines which followed.[br]Principal Honours and DistinctionsAcademy of Sciences, Paris, Gold Medal 1832.Further ReadingB.Bowers, 1982, A History of Electric Light and Power, London, pp. 70–2 (describes the development of Pixii's generator).C.Jackson, 1833, "Notice of the revolving electric magnet of Mr Pixii of Paris", American Journal of Science 24:146–7.GWBiographical history of technology > Pixii, Antoine Hippolyte

99 Ridley, John
SUBJECT AREA: Agricultural and food technology[br]b. 1806 West Boldon, Co. Durham, Englandd. 1887 Malvern, England[br]English developer of the stripper harvester which led to a machine suited to the conditions of Australia and South America.[br]John Ridley was a preacher in his youth, and then became a mill owner before migrating to Australia with his wife and daughters in 1839. Intending to continue his business in the new colony, he took with him a "Grasshopper" overbeam steam-engine made by James Watt, together with milling equipment. Cereal acreages were insufficient for the steam power he had available, and he expanded into saw milling as well as farming 300 acres. Aware of the Adelaide trials of reaping machines, he eventually built a prototype using the same principles as those developed by Wrathall Bull. After a successful trial in 1843 Ridley began the patent procedure in England, although he never completed the project. The agricultural press was highly enthusiastic about his machine, but when trials took place in 1855 the award went to a rival. The development of the stripper enabled a spectacular increase in the cereal acreage planted over the next decade. Ridley left Australia in 1853 and returned to England. He built a number of machines to his design in Leeds; however, these failed to perform in the much damper English climate. All of the machines were exported to South America, anticipating a substantial market to be exploited by Australian manufacturers.[br]Principal Honours and DistinctionsIn 1913 a Ridley scholarship was established by the faculty of Agriculture at Adelaide University.Further ReadingG.Quick and W.Buchele, 1978, The Grain Harvesters, American Society of Agricultural Engineers (includes a chapter devoted to the Australian developments).A.E.Ridley, 1904, A Backward Glance (describes Ridley's own story).G.L.Sutton, 1937, The Invention of the Stripper (a review of the disputed claims between Ridley and Bull).L.J.Jones, 1980, "John Ridley and the South Australian stripper", The History ofTechnology, pp. 55–103 (a more detailed study).——1979, "The early history of mechanical harvesting", The History of Technology, pp. 4,101–48 (discusses the various claims to the first invention of a machine for mechanical harvesting).AP -

He invented a rotary steam engine, which proved impracticable; a rerailing device for railway rolling stock in 1865; and a cast-steel frog for railway points, with longer life than the cast-iron frogs then used, in 1868–9. During the same period Westinghouse, like many other inventors, was considering how best to meet the evident need for a continuous brake for trains, i.e. one by which the driver could apply the brakes on all vehicles in a train simultaneously instead of relying on brakesmen on individual vehicles. By chance he encountered a magazine article about the construction of the Mont Cenis Tunnel, with a description of the pneumatic tools invented for it, and from this it occurred to him that compressed air might be used to operate the brakes along a train.The first prototype was ready in 1869 and the Westinghouse Air Brake Company was set up to manufacture it. However, despite impressive demonstration of the brake's powers when it saved the test train from otherwise certain collision with a horse-drawn dray on a level crossing, railways were at first slow to adopt it. Then in 1872 Westinghouse added to it the triple valve, which enabled the train pipe to charge reservoirs beneath each vehicle, from which the compressed air would apply the brakes when pressure in the train pipe was reduced. This meant that the brake was now automatic: if a train became divided, the brakes on both parts would be applied. From then on, more and more American railways adopted the Westinghouse brake and the Railroad Safety Appliance Act of 1893 made air brakes compulsory in the USA. Air brakes were also adopted in most other parts of the world, although only a minority of British railway companies took them up, the remainder, with insular reluctance, preferring the less effective vacuum brake.From 1880 Westinghouse was purchasing patents relating to means of interlocking railway signals and points; he combined them with his own inventions to produce a complete signalling system. The first really practical power signalling scheme, installed in the USA by Westinghouse in 1884, was operated pneumatically, but the development of railway signalling required an awareness of the powers of electricity, and it was probably this that first led Westinghouse to become interested in electrical processes and inventions. The Westinghouse Electric Company was formed in 1886: it pioneered the use of electricity distribution systems using high-voltage single-phase alternating current, which it developed from European practice. Initially this was violently opposed by established operators of direct-current distribution systems, but eventually the use of alternating current became widespread.[br]Principal Honours and DistinctionsLégion d'honneur.
