7 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.

8 Darby, Abraham
SUBJECT AREA: Metallurgy[br]b. 1678 near Dudley, Worcestershire, Englandd. 5 May 1717 Madely Court, Coalbrookdale, Shropshire, England[br]English ironmaster, inventor of the coke smelting of iron ore.[br]Darby's father, John, was a farmer who also worked a small forge to produce nails and other ironware needed on the farm. He was brought up in the Society of Friends, or Quakers, and this community remained important throughout his personal and working life. Darby was apprenticed to Jonathan Freeth, a malt-mill maker in Birmingham, and on completion of his apprenticeship in 1699 he took up the trade himself in Bristol. Probably in 1704, he visited Holland to study the casting of brass pots and returned to Bristol with some Dutch workers, setting up a brassworks at Baptist Mills in partnership with others. He tried substituting cast iron for brass in his castings, without success at first, but in 1707 he was granted a patent, "A new way of casting iron pots and other pot-bellied ware in sand without loam or clay". However, his business associates were unwilling to risk further funds in the experiments, so he withdrew his share of the capital and moved to Coalbrookdale in Shropshire. There, iron ore, coal, water-power and transport lay close at hand. He took a lease on an old furnace and began experimenting. The shortage and expense of charcoal, and his knowledge of the use of coke in malting, may well have led him to try using coke to smelt iron ore. The furnace was brought into blast in 1709 and records show that in the same year it was regularly producing iron, using coke instead of charcoal. The process seems to have been operating successfully by 1711 in the production of cast-iron pots and kettles, with some pig-iron destined for Bristol. Darby prospered at Coalbrookdale, employing coke smelting with consistent success, and he sought to extend his activities in the neighbourhood and in other parts of the country. However, ill health prevented him from pursuing these ventures with his previous energy. Coke smelting spread slowly in England and the continent of Europe, but without Darby's technological breakthrough the ever-increasing demand for iron for structures and machines during the Industrial Revolution simply could not have been met; it was thus an essential component of the technological progress that was to come.Darby's eldest son, Abraham II (1711–63), entered the Coalbrookdale Company partnership in 1734 and largely assumed control of the technical side of managing the furnaces and foundry. He made a number of improvements, notably the installation of a steam engine in 1742 to pump water to an upper level in order to achieve a steady source of water-power to operate the bellows supplying the blast furnaces. When he built the Ketley and Horsehay furnaces in 1755 and 1756, these too were provided with steam engines. Abraham II's son, Abraham III (1750–89), in turn, took over the management of the Coalbrookdale works in 1768 and devoted himself to improving and extending the business. His most notable achievement was the design and construction of the famous Iron Bridge over the river Severn, the world's first iron bridge. The bridge members were cast at Coalbrookdale and the structure was erected during 1779, with a span of 100 ft (30 m) and height above the river of 40 ft (12 m). The bridge still stands, and remains a tribute to the skill and judgement of Darby and his workers.[br]Further ReadingA.Raistrick, 1989, Dynasty of Iron Founders, 2nd edn, Ironbridge Gorge Museum Trust (the best source for the lives of the Darbys and the work of the company).H.R.Schubert, 1957, History of the British Iron and Steel Industry AD 430 to AD 1775, London: Routledge \& Kegan Paul.LRD -
9 Martin, Pierre Emile
SUBJECT AREA: Metallurgy[br]b. 18 August 1824 Bourges, Franced. 23 May 1915 Fourchambault, France[br]French metallurgist, pioneer of open-hearth steelmaking.[br]His father Emile owned an iron-and steelworks at Sireuil, near Angoulême, and, through this, Pierre became interested in improving the steelmaking process. In England, C.W. Siemens had developed the regenerative principle of waste-heat recovery that produced a much higher furnace temperature. In 1863, the Martins applied this process in an open-hearth furnace built under licence from Siemens, with the aid of his engineers. They melted a mixture of pig-and wrought iron to produce steel with the required carbon content. Martin exhibited the product at the Paris Exhibition of 1867 and was awarded a gold medal. The open-hearth process was for a long time known as the Siemens-Martin process, but Martin did not share in the profits which others gained from its successful adoption. He had difficulty in obtaining patent rights as it was claimed that the principles of the process were already known and in use. The costs of litigation brought Martin to the brink of poverty, from which relief came only late in life, when in 1907 the Comité des Forges de France opened a subscription for him that was generously supported. A week before his death, the Iron and Steel Institute of London bestowed on him their Bessemer gold medal.[br]Principal Honours and DistinctionsIron and Steel Institute Bessemer Gold Medal 1915.Further ReadingObituary, 1915, Journal of the Iron and Steel Institute 91:466.LRD -
