25 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 -
26 Fairbairn, Sir Peter
SUBJECT AREA: Textiles[br]b. September 1799 Kelso, Roxburghshire, Scotlandd. 4 January 1861 Leeds, Yorkshire, England[br]British inventor of the revolving tube between drafting rollers to give false twist.[br]Born of Scottish parents, Fairbairn was apprenticed at the age of 14 to John Casson, a mill-wright and engineer at the Percy Main Colliery, Newcastle upon Tyne, and remained there until 1821 when he went to work for his brother William in Manchester. After going to various other places, including Messrs Rennie in London and on the European continent, he eventually moved in 1829 to Leeds where Marshall helped him set up the Wellington Foundry and so laid the foundations for the colossal establishment which was to employ over one thousand workers. To begin with he devoted his attention to improving wool-weaving machinery, substituting iron for wood in the construction of the textile machines. He also worked on machinery for flax, incorporating many of Philippe de Girard's ideas. He assisted Henry Houldsworth in the application of the differential to roving frames, and it was to these machines that he added his own inventions. The longer fibres of wool and flax need to have some form of support and control between the rollers when they are being drawn out, and inserting a little twist helps. However, if the roving is too tightly twisted before passing through the first pair of rollers, it cannot be drawn out, while if there is insufficient twist, the fibres do not receive enough support in the drafting zone. One solution is to twist the fibres together while they are actually in the drafting zone between the rollers. In 1834, Fairbairn patented an arrangement consisting of a revolving tube placed between the drawing rollers. The tube inserted a "middle" or "false" twist in the material. As stated in the specification, it was "a well-known contrivance… for twisting and untwisting any roving passing through it". It had been used earlier in 1822 by J. Goulding of the USA and a similar idea had been developed by C.Danforth in America and patented in Britain in 1825 by J.C. Dyer. Fairbairn's machine, however, was said to make a very superior article. He was also involved with waste-silk spinning and rope-yarn machinery.Fairbairn later began constructing machine tools, and at the beginning of the Crimean War was asked by the Government to make special tools for the manufacture of armaments. He supplied some of these, such as cannon rifling machines, to the arsenals at Woolwich and Enfield. He then made a considerable number of tools for the manufacture of the Armstrong gun. He was involved in the life of his adopted city and was elected to Leeds town council in 1832 for ten years. He was elected an alderman in 1854 and was Mayor of Leeds from 1857 to 1859, when he was knighted by Queen Victoria at the opening of the new town hall. He was twice married, first to Margaret Kennedy and then to Rachel Anne Brindling.[br]Principal Honours and DistinctionsKnighted 1858.Bibliography1834, British patent no. 6,741 (revolving tube between drafting rollers to give false twist).Further ReadingDictionary of National Biography.Obituary, 1861, Engineer 11.W.English, 1969, The Textile Industry, London (provides a brief account of Fairbairn's revolving tube).C.Singer (ed.), 1958, A History of Technology, Vols IV and V, Oxford: Clarendon Press (provides details of Fairbairn's silk-dressing machine and a picture of a large planing machine built by him).RLH -
27 Heald, James Nichols
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 21 September 1864 Barre, Massachusetts, USAd. 7 May 1931 Worcester, Massachusetts, USA[br]American mechanical engineer and machine-tool manufacturer who concentrated on grinding machines.[br]James N.Heald was the son of Leander S.Heald and was educated at the Worcester Polytechnic Institute, graduating with the degree of Bachelor of Science in 1884. He then joined the firm that had been established by his grandfather, Stephen Heald, in 1826; this was a machine shop and foundry then known as S.Heald \& Son. When his grandfather died in 1888, James Heald took over the management of the business, which then became known as L.S.Heald \& Son. He concentrated on the manufacture of grinding machines and in 1903 bought out his father's interest and organized the Heald Machine Company. James Heald then began the development of a series of grinding machines designed to meet the needs of the expanding automobile industry. Special machines were produced for grinding piston rings making use of the recently invented magnetic chuck, and for cylinder bores he introduced the planetary grinder. Heald was a member of the National Machine Tool Builders' Association and served as its Treasurer and on its Board of Directors. He was elected a member of the American Society of Mechanical Engineers in 1917 and was also a member of the Society of Automotive Engineers.[br]Further ReadingRobert S.Woodbury, 1959, History of the Grinding Machine, Cambridge, Mass (describes his grinding machines).L.T.C.Rolt, 1965, Tools for the Job, London; repub. 1986 (describes his grinding machines).RTS -
28 Junghans, Siegfried
SUBJECT AREA: Metallurgy[br]b. 1887d. 1954[br]German pioneer of the continuous casting of metals.[br]Junghans was of the family that owned Gebrüder Junghans, one of the largest firms in the German watch-and clockmaking industry. From 1906 to 1918 he served in the German Army, after which he took a course in metallurgy and analytical chemistry at the Technical High School in Stuttgart. Junghans was then given control of the brassworks owned by his family. He wanted to make castings simply and cheaply, but he found that he lacked the normal foundry equipment. By 1927, formulating his ideas on continuous casting, he had conceived a way of overcoming this deficiency and began experiments. By the time the firm was taken over by Wieland-Werke AG in 1931, Junghans had achieved positive results. A test plant was erected in 1932, and commercial production of continuously cast metal followed the year after. Wieland told Junghans that a brassfounder who had come up through the trade would never have hit on the idea: it took an outsider like Junghans to do it. He was made Technical Director of Wielands but left in 1935 to work privately on the development of continuous casting for all metals. He was able to license the process for non-ferrous metals during 1936–9 in Germany and other countries, but the Second World War interrupted his work; however, the German government supported him and a production plant was built. In 1948 he was able to resume work on the continuous casting of steel, which he had been considering since 1936. He pushed on in spite of financial difficulties and produced the first steel by this process at Schorndorf in March 1949. From 1950 he made agreements with four firms to work towards the pilot plant stage, and this was achieved in 1954 at Mannesmann's Huckingen works. The aim of continuous casting is to bypass the conventional processes of casting molten steel into ingots, reheating the ingots and shaping them by rolling them in a large mill. Essentially, in continuous casting, molten steel is drawn through the bottom of a ladle and down through a water-cooled copper mould. The unique feature of Junghans's process was the vertically reciprocating mould, which prevented the molten metal sticking as it passed through. A continuous length of steel is taken off and cooled until it is completely solidified into the required shape. The idea of continuous casting can be traced back to Bessemer, and although others tried to apply it later, they did not have any success. It was Junghans who, more than anybody, made the process a reality.[br]Further ReadingK.Sperth and A.Bungeroth, 1953, "The Junghans method of continuous casting of steel", Metal Treatment and Drop Forging, Mayn.J.Jewkes et al., 1969, The Sources of Invention, 2nd edn, London: Macmillan, pp. 287 ff.LRD -
29 Murdock (Murdoch), William
[br]b. 21 August 1754 Cumnock, Ayrshire, Scotlandd. 15 November 1839 Handsworth, Birmingham, England[br]Scottish engineer and inventor, pioneer in coal-gas production.[br]He was the third child and the eldest of three boys born to John Murdoch and Anna Bruce. His father, a millwright and joiner, spelled his name Murdock on moving to England. He was educated for some years at Old Cumnock Parish School and in 1777, with his father, he built a "wooden horse", supposed to have been a form of cycle. In 1777 he set out for the Soho manufactory of Boulton \& Watt, where he quickly found employment, Boulton supposedly being impressed by the lad's hat. This was oval and made of wood, and young William had turned it himself on a lathe of his own manufacture. Murdock quickly became Boulton \& Watt's representative in Cornwall, where there was a flourishing demand for steam-engines. He lived at Redruth during this period.It is said that a number of the inventions generally ascribed to James Watt are in fact as much due to Murdock as to Watt. Examples are the piston and slide valve and the sun-and-planet gearing. A number of other inventions are attributed to Murdock alone: typical of these is the oscillating cylinder engine which obviated the need for an overhead beam.In about 1784 he planned a steam-driven road carriage of which he made a working model. He also planned a high-pressure non-condensing engine. The model carriage was demonstrated before Murdock's friends and travelled at a speed of 6–8 mph (10–13 km/h). Boulton and Watt were both antagonistic to their employees' developing independent inventions, and when in 1786 Murdock set out with his model for the Patent Office, having received no reply to a letter he had sent to Watt, Boulton intercepted him on the open road near Exeter and dissuaded him from going any further.In 1785 he married Mary Painter, daughter of a mine captain. She bore him four children, two of whom died in infancy, those surviving eventually joining their father at the Soho Works. Murdock was a great believer in pneumatic power: he had a pneumatic bell-push at Sycamore House, his home near Soho. The pattern-makers lathe at the Soho Works worked for thirty-five years from an air motor. He also conceived the idea of a vacuum piston engine to exhaust a pipe, later developed by the London Pneumatic Despatch Company's railway and the forerunner of the atmospheric railway.Another field in which Murdock was a pioneer was the gas industry. In 1791, in Redruth, he was experimenting with different feedstocks in his home-cum-office in Cross Street: of wood, peat and coal, he preferred the last. He designed and built in the backyard of his house a prototype generator, washer, storage and distribution plant, and publicized the efficiency of coal gas as an illuminant by using it to light his own home. In 1794 or 1795 he informed Boulton and Watt of his experimental work and of its success, suggesting that a patent should be applied for. James Watt Junior was now in the firm and was against patenting the idea since they had had so much trouble with previous patents and had been involved in so much litigation. He refused Murdock's request and for a short time Murdock left the firm to go home to his father's mill. Boulton \& Watt soon recognized the loss of a valuable servant and, in a short time, he was again employed at Soho, now as Engineer and Superintendent at the increased salary of £300 per year plus a 1 per cent commission. From this income, he left £14,000 when he died in 1839.In 1798 the workshops of Boulton and Watt were permanently lit by gas, starting with the foundry building. The 180 ft (55 m) façade of the Soho works was illuminated by gas for the Peace of Paris in June 1814. By 1804, Murdock had brought his apparatus to a point where Boulton \& Watt were able to canvas for orders. Murdock continued with the company after the death of James Watt in 1819, but retired in 1830 and continued to live at Sycamore House, Handsworth, near Birmingham.[br]Principal Honours and DistinctionsRoyal Society Rumford Gold Medal 1808.Further ReadingS.Smiles, 1861, Lives of the Engineers, Vol. IV: Boulton and Watt, London: John Murray.H.W.Dickinson and R.Jenkins, 1927, James Watt and the Steam Engine, Oxford: Clarendon Press.J.A.McCash, 1966, "William Murdoch.
