1 Rowland, Thomas Fitch
SUBJECT AREA: Mining and extraction technology[br]b. 15 March 1831 New Haven, Connecticut, USAd. 13 December 1907 New York City, USA[br]American engineer and manufacturer, inventor of off-shore drilling.[br]The son of a grist miller, Rowland worked in various jobs until 1859 when he established his own business for the construction of wooden and iron steamships and for structural iron works, in Greenpoint, Long Island, New York. In 1860 he founded the Continental Works and during the American Civil War he started manufacturing gun carriages and mortar beds. He fitted out many vessels for the navy, and as a contractor for John Ericsson he built heavily armoured war vessels.He continued shipbuilding, but later diversified his business. He devoted great attention to the design of gas-works, constructing innovative storage facilities all over the United States, and he was concerned with the improvement of welding iron and steel plates and other processes in the steel industry. In the late 1860s he also began the manufacture of steam-engines and boilers for use in the new but expanding oil industry. In 1869 he took out a patent for a fixed platform for drilling for oil off-shore up to a depth of 15 m (49 ft). With this idea, just ten years after Edwin Drake's success in on-shore oil drilling in Titusville, Pennsylvania, Rowland pioneered the technology of off-shore drilling for petroleum in which the United States later became the leading nation.[br]Principal Honours and DistinctionsAmerican Society of Civil Engineers: Director 1871–3, Vice-President 1886–7, Honorary Member 1899.Further Reading"Thomas Fitch Rowland", Dictionary of American Biography.1909, "Memoir", Transactions of the American Society of Civil Engineers 62:547–9.WK -
2 Bond, George Meade
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 17 July 1852 Newburyport, Massachusetts, USAd. 6 January 1935 Hartford, Connecticut, USA[br]American mechanical engineer and metrologist, co-developer of the Rogers- Bond Comparator.[br]After leaving school at the age of 17, George Bond taught in local schools for a few years before starting an apprenticeship in a machine shop in Grand Rapids, Michigan. He then worked as a machinist with Phoenix Furniture Company in that city until his savings permitted him to enter the Stevens Institute of Technology at Hoboken, New Jersey, in 1876. He graduated with the degree of Mechanical Engineer in 1880. In his final year he assisted William A.Rogers, Professor of Astronomy at Harvard College Observatory, Cambridge, Massachusetts, in the design of a comparator for checking standards of length. In 1880 he joined the Pratt \& Whitney Company, Hartford, Connecticut, and was Manager of the Standards and Gauge Department from then until 1902. During this period he developed cylindrical, calliper, snap, limit, thread and other gauges. He also designed the Bond Standard Measuring Machine. Bond was elected a member of the American Society of Mechanical Engineers in 1881 and of the American Society of Civil Engineers in 1887, and served on many of their committees relating to standards and units of measurement.[br]Principal Honours and DistinctionsVice-President, American Society of Mechanical Engineers 1908–10.

3 Bodmer, Johann Georg
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering, Railways and locomotives, Steam and internal combustion engines, Textiles, Weapons and armour[br]b. 9 December 1786 Zurich, Switzerlandd. 30 May 1864 Zurich, Switzerland[br]Swiss mechanical engineer and inventor.[br]John George Bodmer (as he was known in England) showed signs of great inventive ability even as a child. Soon after completing his apprenticeship to a local millwright, he set up his own work-shop at Zussnacht. One of his first inventions, in 1805, was a shell which exploded on impact. Soon after this he went into partnership with Baron d'Eichthal to establish a cotton mill at St Blaise in the Black Forest. Bodmer designed the water-wheels and all the machinery. A few years later they established a factory for firearms and Bodmer designed special machine tools and developed a system of interchangeable manufacture comparable with American developments at that time. More inventions followed, including a detachable bayonet for breech-loading rifles and a rifled, breech-loading cannon for 12 lb (5.4 kg) shells.Bodmer was appointed by the Grand Duke of Baden to the posts of Director General of the Government Iron Works and Inspector of Artillery. He left St Blaise in 1816 and entered completely into the service of the Grand Duke, but before taking up his duties he visited Britain for the first time and made an intensive five-month tour of textile mills, iron works, workshops and similar establishments.In 1821 he returned to Switzerland and was engaged in setting up cotton mills and other engineering works. In 1824 he went back to England, where he obtained a patent for his improvements in cotton machinery and set up a mill near Bolton incorporating his ideas. His health failing, he was obliged to return to Switzerland in 1828, but he was soon busy with engineering works there and in France. In 1833 he went to England again, first to Bolton and four years later to Manchester in partnership with H.H.Birley. In the next ten years he patented many more inventions in the fields of textile machinery, steam engines and machine tools. These included a balanced steam engine, a mechanical stoker, steam engine valve gear, gear-cutting machines and a circular planer or vertical lathe, anticipating machines of this type later developed in America by E.P. Bullard. The metric system was used in his workshops and in gearing calculations he introduced the concept of diametral pitch, which then became known as "Manchester Pitch". The balanced engine was built in stationary form and in two locomotives, but although their running was remarkably smooth the additional complication prevented their wider use.After the death of H.H.Birley in 1846, Bodmer removed to London until 1848, when he went to Austria. About 1860 he returned to his native town of Zurich. He remained actively engaged in all kinds of inventions up to the end of his life. He obtained fourteen British patents, each of which describes many inventions; two of these patents were extended beyond the normal duration of fourteen years. Two others were obtained on his behalf, one by his brother James in 1813 for his cannon and one relating to railways by Charles Fox in 1847. Many of his inventions had little direct influence but anticipated much later developments. His ideas were sound and some of his engines and machine tools were in use for over sixty years. He was elected a Member of the Institution of Civil Engineers in 1835.[br]Bibliography1845, "The advantages of working stationary and marine engines with high-pressure steam, expansively and at great velocities; and of the compensating, or double crank system", Minutes of the Proceedings of the Institution of Civil Engineers 4:372–99.1846, "On the combustion of fuel in furnaces and steam-boilers, with a description of Bodmer's fire-grate", Minutes of the Proceedings of the Institution of Civil Engineers 5:362–8.Further ReadingObituary, 1868–9, Minutes of the Proceedings of the Institution of Civil Engineers 28:573–608.H.W.Dickinson, 1929–30, "Diary of John George Bodmer, 1816–17", Transactions of the Newcomen Society 10:102–14.D.Brownlie, 1925–6, John George Bodmer, his life and work, particularly in relation to the evolution of mechanical stoking', Transactions of the Newcomen Society 6:86–110.W.O.Henderson (ed.), 1968, Industrial Britain Under the Regency: The Diaries of Escher, Bodmer, May and de Gallois 1814–1818, London: Frank Cass (a more complete account of his visit to Britain).RTS -
4 Fox, Samson
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering, Metallurgy, Steam and internal combustion engines[br]b. 11 July 1838 Bowling, near Bradford, Yorkshire, Englandd. 24 October 1903 Walsall, Staffordshire, England[br]English engineer who invented the corrugated boiler furnace.[br]He was the son of a cloth mill worker in Leeds and at the age of 10 he joined his father at the mill. Showing a mechanical inclination, he was apprenticed to a firm of machine-tool makers, Smith, Beacock and Tannett. There he rose to become Foreman and Traveller, and designed and patented tools for cutting bevelled gears. With his brother and one Refitt, he set up the Silver Cross engineering works for making special machine tools. In 1874 he founded the Leeds Forge Company, acting as Managing Director until 1896 and then as Chairman until shortly before his death.It was in 1877 that he patented his most important invention, the corrugated furnace for steam-boilers. These furnaces could withstand much higher pressures than the conventional form, and higher working pressures in marine boilers enabled triple-expansion engines to be installed, greatly improving the performance of steamships, and the outcome was the great ocean-going liners of the twentieth century. The first vessel to be equipped with the corrugated furnace was the Pretoria of 1878. At first the furnaces were made by hammering iron plates using swage blocks under a steam hammer. A plant for rolling corrugated plates was set up at Essen in Germany, and Fox installed a similar mill at his works in Leeds in 1882.In 1886 Fox installed a Siemens steelmaking plant and he was notable in the movement for replacing wrought iron with steel. He took out several patents for making pressed-steel underframes for railway wagons. The business prospered and Fox opened a works near Chicago in the USA, where in addition to wagon underframes he manufactured the first American pressed-steel carriages. He later added a works at Pittsburgh.Fox was the first in England to use water gas for his metallurgical operations and for lighting, with a saving in cost as it was cheaper than coal gas. He was also a pioneer in the acetylene industry, producing in 1894 the first calcium carbide, from which the gas is made.Fox took an active part in public life in and around Leeds, being thrice elected Mayor of Harrogate. As a music lover, he was a benefactor of musicians, contributing no less than £45,000 towards the cost of building the Royal College of Music in London, opened in 1894. In 1897 he sued for libel the author Jerome K.Jerome and the publishers of the Today magazine for accusing him of misusing his great generosity to the College to give a misleading impression of his commercial methods and prosperity. He won the case but was not awarded costs.[br]Principal Honours and DistinctionsRoyal Society of Arts James Watt Silver Medal and Howard Gold Medal.
