2 Moulton, Alexander
[br]b. 9 April 1920 Stratford-on-Avon[br]English inventor of vehicle suspension systems and the Moulton bicycle.[br]He spent his childhood at The Hall in Bradfordon-Avon. He was educated at Marlborough College, and in 1937 was apprenticed to the Sentinel Steam Wagon Company of Shrewsbury. About that same time he went to King's College, Cambridge, where he took the Mechanical Sciences Tripos. It was then wartime, and he did research on aero-engines at the Bristol Aeroplane Company, where he became Personal Assistant to Sir Roy Fedden. He left Bristol's in 1945 to join his family firm, Spencer \& Moulton, of which he eventually became Technical Director and built up the Research Department. In 1948 he invented his first suspension unit, the "Flexitor", in which an inner shaft and an outer shell were separated by an annular rubber body which was bonded to both.In 1848 his great-grandfather had founded the family firm in an old woollen mill, to manufacture vulcanized rubber products under Charles Goodyear's patent. The firm remained a family business with Spencer's, consultants in railway engineering, until 1956 when it was sold to the Avon Rubber Company. He then formed Moulton Developments to continue his work on vehicle suspensions in the stables attached to The Hall. Sponsored by the British Motor Corporation (BMC) and the Dunlop Rubber Company, he invented a rubber cone spring in 1951 which was later used in the BMC Mini (see Issigonis, Sir Alexander Arnold Constantine): by 1994 over 4 million Minis had been fitted with these springs, made by Dunlop. In 1954 he patented the Hydrolastic suspension system, in which all four wheels were independently sprung with combined rubber springs and damper assembly, the weight being supported by fluid under pressure, and the wheels on each side being interconnected, front to rear. In 1962 he formed Moulton Bicycles Ltd, having designed an improved bicycle system for adult use. The conventional bicycle frame was replaced by a flat-sided oval steel tube F-frame on a novel rubber front and rear suspension, with the wheel size reduced to 41 cm (16 in.) with high-pressure tyres. Raleigh Industries Ltd having refused his offer to produce the Moulton Bicycle under licence, he set up his own factory on his estate, producing 25,000 bicycles between 1963 and 1966. In 1967 he sold out to Raleigh and set up as Bicycle Consultants Ltd while continuing the suspension development of Moulton Developments Ltd. In the 1970s the combined firms employed some forty staff, nearly 50 per cent of whom were graduates.He won the Queen's Award for Industry in 1967 for technical innovation in Hydrolastic car suspension and the Moulton Bicycle. Since that time he has continued his innovative work on suspensions and the bicycle. In 1983 he introduced the AM bicycle series of very sophisticated space-frame design with suspension and 43 cm (17 in.) wheels; this machine holds the world speed record fully formed at 82 km/h (51 mph). The current Rover 100 and MGF use his Hydragas interconnected suspension. By 1994 over 7 million cars had been fitted with Moulton suspensions. He has won many design awards and prizes, and has been awarded three honorary doctorates of engineering. He is active in engineering and design education.[br]Principal Honours and DistinctionsQueen's Award for Industry 1967; CBE; RDI.

3 Norton, Charles Hotchkiss
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 23 November 1851 Plainville, Connecticut, USAd. 27 October 1942 Plainville, Connecticut, USA[br]American mechanical engineer and machine-tool designer.[br]After an elementary education at the public schools of Plainville and Thomaston, Connecticut, Charles H.Norton started work in 1866 at the Seth Thomas Clock Company in Thomaston. He was soon promoted to machinist, and further progress led to his successive appointments as Foreman, Superintendent of Machinery and Manager of the department making tower clocks. He designed many public clocks.In 1886 he obtained a position as Assistant Engineer with the Brown \& Sharpe Manufacturing Company at Providence, Rhode Island, and was engaged in redesigning their universal grinding machine to give it more rigidity and make it more suitable for use as a production machine. In 1890 he left to become a partner in a newly established firm, Leland, Faulconer \& Norton Company at Detroit, Michigan, designing and building machine tools. He withdrew from this firm in 1895 and practised as a consulting mechanical engineer for a short time before returning to Brown \& Sharpe in 1896. There he designed a grinding machine incorporating larger and wider grinding wheels so that heavier cuts could be made to meet the needs of the mass-production industries, especially the automobile industry. This required a heavier and more rigid machine and greater power, but these ideas were not welcomed at Brown \& Sharpe and in 1900 Norton left to found the Norton Grinding Company in Worcester, Massachusetts. Here he was able to develop heavy-production grinding machines, including special machines for grinding crank-shafts and camshafts for the automobile industry.In setting up the Norton Grinding Company, Charles H.Norton received financial support from members of the Norton Emery Wheel Company (also of Worcester and known after 1906 as the Norton Company), but he was not related to the founder of that company. The two firms were completely independent until 1919 when they were merged. From that time Charles H.Norton served as Chief Engineer of the machinery division of the Norton Company, until 1934 when he became their Consulting Engineer.[br]Principal Honours and DistinctionsCity of Philadelphia, John Scott Medal 1925.BibliographyNorton was granted more than one hundred patents and was author of Principles of Cylindrical Grinding, 1917, 1921, Worcester, Mass.Further ReadingRobert S.Woodbury, 1959, History of the Grinding Machine, Cambridge, Mass, (contains biographical information and details of the machines designed by Norton).RTSBiographical history of technology > Norton, Charles Hotchkiss

5 Shoenberg, Isaac
[br]b. 1 March 1880 Kiev, Ukrained. 25 January 1963 Willesden, London, England[br]Russian engineer and friend of Vladimir Zworykin; Director of Research at EMI, responsible for creating the team that successfully developed the world's first all-electronic television system.[br]After his initial engineering education at Kiev Polytechnic, Shoenberg went to London to undertake further studies at the Royal College of Science. In 1905 he returned to Russia and rose to become Chief Engineer of the Russian Wireless Telegraphy Company. He then returned to England, where he was a consultant in charge of the Patent Department and then joint General Manager of the Marconi Wireless Telegraphy Company (see Marconi). In 1929 he joined the Columbia Graphophone Company, but two years later this amalgamated with the Gramophone Company, by then known as His Master's voice (HMV), to form EMI (Electric and Musical Industries), a company in which the Radio Corporation of America (RCA) had a significant shareholding. Appointed Director of the new company's Research Laboratories in 1931, Shoenberg gathered together a team of highly skilled engineers, including Blumlein, Browne, Willans, McGee, Lubszynski, Broadway and White, with the objective of producing an all-electronic television system suitable for public broadcasting. A 150-line system had already been demonstrated using film as the source material; a photoemissive camera tube similar to Zworykin's iconoscope soon followed. With alternate demonstrations of the EMI system and the mechanical system of Baird arranged with the object of selecting a broadcast system for the UK, Shoenberg took the bold decision to aim for a 405-line "high-definition" standard, using interlaced scanning based on an RCA patent and further developed by Blumlein. This was so successful that it was formally adopted as the British standard in 1935 and regular broadcasts, the first in the world, began in 1937. It is a tribute to Shoenberg's vision and the skills of his team that this standard was to remain in use, apart from the war years, until finally superseded in 1985.[br]Principal Honours and DistinctionsKnighted 1954.

6 Fox, James
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. c.1760d. 1835 Derby, England[br]English machine-tool builder.[br]Very little is known about the life of James Fox, but according to Samuel Smiles (1863) he was as a young man a butler in the service of the Reverend Thomas Gisborne of Foxhall Lodge, Staffordshire. His mechanical abilities were evident from his spare-time activities in the handling of tools and so impressed his employer that he supplied the capital to enable Fox to set up a business in Derby for the manufacture of machinery for the textile and lacemaking industries. To construct this machinery, Fox had to build his own machine tools and later, in the early nineteenth century, made them for sale, some being exported to France, Germany and Poland. He was renowned for his lathes, some of which were quite large; one built in 1830 has been preserved and is 22 ft (6.7 m) long with a swing of 27 in. (69 cm). He was responsible for many improve-ments in the design of the lathe and he also built some of the earliest planing machines (the first, it has been claimed, as early as 1814) and a gear-cutting machine, although this was apparently for cutting wooden patterns for cast gears. The business was continued by his sons Joseph and James (who died in 1859 aged 69) and into the 1860s by the sons of Joseph.[br]Further ReadingS.Smiles, 1863, Industrial Biography, London, reprinted 1967, Newton Abbot (makes brief mention of Fox).Letters relating to the invention of the planing machine can be found in Engineer 14 (1862): 189, 204, 219, 246 and 247.His lathes are described in: R.S.Woodbury, 1961, History of the Lathe to 1850, Cleveland, Ohio; L.T.C.Rolt, 1965, Tools for the Job, London; repub. 1986; W.Steeds, 1969, A History of Machine Tools 1700–1910, Oxford.RTS -
7 Reynolds, Edwin
[br]b. 1831 Mansfield, Connecticut, USAd. 1909 Milwaukee, Wisconsin, USA[br]American contributor to the development of the Corliss valve steam engine, including the "Manhattan" layout.[br]Edwin Reynolds grew up at a time when formal engineering education in America was almost unavailable, but through his genius and his experience working under such masters as G.H. Corliss and William Wright, he developed into one of the best mechanical engineers in the country. When he was Plant Superintendent for the Corliss Steam Engine Company, he built the giant Corliss valve steam engine displayed at the 1876 Centennial Exhibition. In July 1877 he left the Corliss Steam Engine Company to join Edward Allis at his Reliance Works, although he was offered a lower salary. In 1861 Allis had moved his business to the Menomonee Valley, where he had the largest foundry in the area. Immediately on his arrival with Allis, Reynolds began desig-ning and building the "Reliance-Corliss" engine, which becamea symbol of simplicity, economy and reliability. By early 1878 the new engine was so successful that the firm had a six-month backlog of orders. In 1888 he built the first triple-expansion waterworks-pumping engine in the United States for the city of Milwaukee, and in the same year he patented a new design of blowing engine for blast furnaces. He followed this in March 1892 with the first steam engine sets coupled directly to electric generators when Allis-Chalmers contracted to build two Corliss cross-compound engines for the Narragansett Light Company of Providence, Rhode Island. In 1893, one of the impressive attractions at the World's Columbian Exposition in Chicago was the 3,000 hp (2,200 kW) quadruple-expansion Reynolds-Corliss engine designed by Reynolds, who continued to make significant improvements and gained worldwide recognition of his outstanding achievements in engine building.Reynolds was asked to go to New York in 1898 for consultation about some high-horsepower engines for the Manhattan transport system. There, 225 railway locomotives were to be replaced by electric trains, which would be supplied from one generating station producing 60,000 hp (45,000 kW). Reynolds sketched out his ideas for 10,000 hp (7,500 kW) engines while on the train. Because space was limited, he suggested a four-cylinder design with two horizontal-high-pressure cylinders and two vertical, low-pressure ones. One cylinder of each type was placed on each side of the flywheel generator, which with cranks at 135° gave an exceptionally smooth-running compact engine known as the "Manhattan". A further nine similar engines that were superheated and generated three-phase current were supplied in 1902 to the New York Interborough Rapid Transit Company. These were the largest reciprocating steam engines built for use on land, and a few smaller ones with a similar layout were installed in British textile mills.[br]Further ReadingConcise Dictionary of American Biography, 1964, New York: C.Scribner's Sons (contains a brief biography).R.L.Hills, 1989, Power from Steam.
