10 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

11 Trevithick, Richard
[br]b. 13 April 1771 Illogan, Cornwall, Englandd. 22 April 1833 Dartford, Kent, England[br]English engineer, pioneer of non-condensing steam-engines; designed and built the first locomotives.[br]Trevithick's father was a tin-mine manager, and Trevithick himself, after limited formal education, developed his immense engineering talent among local mining machinery and steam-engines and found employment as a mining engineer. Tall, strong and high-spirited, he was the eternal optimist.About 1797 it occurred to him that the separate condenser patent of James Watt could be avoided by employing "strong steam", that is steam at pressures substantially greater than atmospheric, to drive steam-engines: after use, steam could be exhausted to the atmosphere and the condenser eliminated. His first winding engine on this principle came into use in 1799, and subsequently such engines were widely used. To produce high-pressure steam, a stronger boiler was needed than the boilers then in use, in which the pressure vessel was mounted upon masonry above the fire: Trevithick designed the cylindrical boiler, with furnace tube within, from which the Cornish and later the Lancashire boilers evolved.Simultaneously he realized that high-pressure steam enabled a compact steam-engine/boiler unit to be built: typically, the Trevithick engine comprised a cylindrical boiler with return firetube, and a cylinder recessed into the boiler. No beam intervened between connecting rod and crank. A master patent was taken out.Such an engine was well suited to driving vehicles. Trevithick built his first steam-carriage in 1801, but after a few days' use it overturned on a rough Cornish road and was damaged beyond repair by fire. Nevertheless, it had been the first self-propelled vehicle successfully to carry passengers. His second steam-carriage was driven about the streets of London in 1803, even more successfully; however, it aroused no commercial interest. Meanwhile the Coalbrookdale Company had started to build a locomotive incorporating a Trevithick engine for its tramroads, though little is known of the outcome; however, Samuel Homfray's ironworks at Penydarren, South Wales, was already building engines to Trevithick's design, and in 1804 Trevithick built one there as a locomotive for the Penydarren Tramroad. In this, and in the London steam-carriage, exhaust steam was turned up the chimney to draw the fire. On 21 February the locomotive hauled five wagons with 10 tons of iron and seventy men for 9 miles (14 km): it was the first successful railway locomotive.Again, there was no commercial interest, although Trevithick now had nearly fifty stationary engines completed or being built to his design under licence. He experimented with one to power a barge on the Severn and used one to power a dredger on the Thames. He became Engineer to a project to drive a tunnel beneath the Thames at Rotherhithe and was only narrowly defeated, by quicksands. Trevithick then set up, in 1808, a circular tramroad track in London and upon it demonstrated to the admission-fee-paying public the locomotive Catch me who can, built to his design by John Hazledine and J.U. Rastrick.In 1809, by which date Trevithick had sold all his interest in the steam-engine patent, he and Robert Dickinson, in partnership, obtained a patent for iron tanks to hold liquid cargo in ships, replacing the wooden casks then used, and started to manufacture them. In 1810, however, he was taken seriously ill with typhus for six months and had to return to Cornwall, and early in 1811 the partners were bankrupt; Trevithick was discharged from bankruptcy only in 1814.In the meantime he continued as a steam engineer and produced a single-acting steam engine in which the cut-off could be varied to work the engine expansively by way of a three-way cock actuated by a cam. Then, in 1813, Trevithick was approached by a representative of a company set up to drain the rich but flooded silver-mines at Cerro de Pasco, Peru, at an altitude of 14,000 ft (4,300 m). Low-pressure steam engines, dependent largely upon atmospheric pressure, would not work at such an altitude, but Trevithick's high-pressure engines would. Nine engines and much other mining plant were built by Hazledine and Rastrick and despatched to Peru in 1814, and Trevithick himself followed two years later. However, the war of independence was taking place in Peru, then a Spanish colony, and no sooner had Trevithick, after immense difficulties, put everything in order at the mines then rebels arrived and broke up the machinery, for they saw the mines as a source of supply for the Spanish forces. It was only after innumerable further adventures, during which he encountered and was assisted financially by Robert Stephenson, that Trevithick eventually arrived home in Cornwall in 1827, penniless.He petitioned Parliament for a grant in recognition of his improvements to steam-engines and boilers, without success. He was as inventive as ever though: he proposed a hydraulic power transmission system; he was consulted over steam engines for land drainage in Holland; and he suggested a 1,000 ft (305 m) high tower of gilded cast iron to commemorate the Reform Act of 1832. While working on steam propulsion of ships in 1833, he caught pneumonia, from which he died.[br]BibliographyTrevithick took out fourteen patents, solely or in partnership, of which the most important are: 1802, Construction of Steam Engines, British patent no. 2,599. 1808, Stowing Ships' Cargoes, British patent no. 3,172.Further ReadingH.W.Dickinson and A.Titley, 1934, Richard Trevithick.
