2 Huntsman, Benjamin
SUBJECT AREA: Metallurgy[br]b. 1704 Barton-on-Humber, Lincolnshire, Englandd. 21 June 1776 Sheffield, England[br]English inventor of crucible steelmaking.[br]Of Dutch descent, Hunstman was apprenticed to a clockmaker at Epworth, Lincolnshire. In 1725 he set up in Doncaster as a maker of clocks, locks and roasting jacks. He made improvements in his tools but found himself hampered by the poor quality of the steel available, then made by the cementation process, which yielded a steel with a non-uniform carbon content. Around 1740, Huntsman moved to Handsworth, now part of Sheffield, and began experimenting by heating varying compositions of fuel and flux with crude steel in a crucible, to obtain a steel of uniform composition. During the years 1745 to 1750 he attained his object, but not without many unsuccessful "heats", as excavations of the site of his works now reveal. Although his steel was far better than that previously available, however, the conservative cutlers of Sheffield rejected it, claiming it was too hard to work; therefore Huntsman exported his product to France, where the cutlers promptly worked it into high-quality knives and razors that were exported to England. The Sheffield cutlers' attempts to prevent Huntsman from exporting his steel proved unsuccessful. Huntsman did not patent his process, preferring to retain his advantage by shrouding his work in secrecy, carrying out his melting at night to escape observation, but a rival cutler, Samuel Walker, gained admittance to Huntsman's works disguised as a tramp seeking food. As a result, Walker was able to make crucible steel at a handsome profit. Huntsman fought back and earned success through the sheer quality of his steel, and had to move to.a larger site at Attercliffe in 1770. Crucible steelmaking remained important through the nineteenth century although, as it was a small-scale process, its application was restricted to engineers' cutting tools and the cutting edges of certain tools.[br]Further ReadingE.W.Hulme, 1945, "The pedigree and career of Benjamin Huntsman, inventor in Europe of crucible steel", Transactions of the Newcomen Society 24:37–48.W.K.V.Gale, 1969, Iron and Steel, London: Longman.LRD -

4 Borsig, Johann Carl Friedrich August
[br]b. 25 June 1804 Breslau, Germany (now Wroclaw, Poland)d. 7 July 1854 Berlin, Germany[br]German pioneer manufacturer of locomotives and rails.[br]Borsig established a small works at Berlin in 1837 that ten years later had expanded sufficiently to employ 1,200 people. In that year it produced sixty-seven locomotives. Borsig copied the long-boiler type then popular in Britain and which had been exported to Germany by British manufacturers: it became the standard goods engine in Germany for many years, and the name Borsig became one of the famous names of locomotive building. In 1847 Borsig established an iron-works near Berlin that from 1851 started to produce good-quality rails; German railways previously had to import these from Britain.[br]Further ReadingJ.Marshall, 1978, A Biographical Dictionary of Railway Engineers, Newton Abbot: David \& Charles.PJGRBiographical history of technology > Borsig, Johann Carl Friedrich August

5 Radcliffe, William
SUBJECT AREA: Textiles[br]b. 1761 Mellor, Cheshire, Englandd. 1842 Mellor, Cheshire, England[br]English inventor of the sizing machine.[br]Radcliffe was brought up in the textile industry and learned carding and spinning as a child. When he was old enough, he became a weaver. It was a time when there were not enough weavers to work up all the yarn being spun on the recently invented spinning machines, so some yarn was exported. Radcliffe regarded this as a sin; meetings were held to prohibit the export, and Radcliffe promised to use his best endeavours to discover means to work up the yarn in England. He owned a mill at Mellor and by 1801 was employing over 1,000 hand-loom weavers. He wanted to improve their efficiency so they could compete against power looms, which were beginning to be introduced at that time.His first step was to divide up as much as possible the different weaving processes, not unlike the plan adopted by Arkwright in spinning. In order to strengthen the warp yarns made of cotton and to reduce their tendency to fray during weaving, it was customary to apply an adhesive substance such as starch paste. This was brushed on as the warp was unwound from the back beam during weaving, so only short lengths could be treated before being dried. Instead of dressing the warp in the loom as was hitherto done, Radcliffe had it dressed in a separate machine, relieving the weaver of the trouble and saving the time wasted by the method previously used. Radcliffe employed a young man names Thomas Johnson, who proved to be a clever mechanic. Radcliffe patented his inventions in Johnson's name to avoid other people, especially foreigners, finding out his ideas. He took out his first patent, for a dressing machine, in March 1803 and a second the following year. The combined result of the two patents was the introduction of a beaming machine and a dressing machine which, in addition to applying the paste to the yarns and then drying them, wound them onto a beam ready for the loom. These machines enabled the weaver to work a loom with fewer stoppages; however, Radcliffe did not anticipate that his method of sizing would soon be applied to power looms as well and lead to the commercial success of powered weaving. Other manufacturers quickly adopted Radcliffe's system, and Radcliffe himself soon had to introduce power looms in his own business.Radcliffe improved the hand looms themselves when, with the help of Johnson, he devised a cloth taking-up motion that wound the woven cloth onto a roller automatically as the weaver operated the loom. Radcliffe and Johnson also developed the "dandy loom", which was a more compact form of hand loom and was also later adapted for weaving by power. Radcliffe was among the witnesses before the Parliamentary Committee which in 1808 awarded Edmund Cartwright a grant for his invention of the power loom. Later Radcliffe was unsuccessfully to petition Parliament for a similar reward for his contributions to the introduction of power weaving. His business affairs ultimately failed partly through his own obstinacy and his continued opposition to the export of cotton yarn. He lived to be 81 years old and was buried in Mellor churchyard.[br]Bibliography1811, Exportation of Cotton Yarn and Real Cause of the Distress that has Fallen upon the Cotton Trade for a Series of Years Past, Stockport.1828, Origin of the New System of Manufacture, Commonly Called "Power-Loom Weaving", Stockport (this should be read, even though it is mostly covers Radcliffe's political aims).Further ReadingA.Barlow, 1870, The History and Principles of Weaving by Hand and by Power, London (provides an outline of Radcliffe's life and work).W.English, 1969, The Textile Industry, London (a general background of his inventions).

6 Singer, Isaac Merritt
[br]b. 27 October 1811 Pittstown, New York, USAd. 23 July 1875 Torquay, Devonshire, England[br]American inventor of a sewing machine, and pioneer of mass production.[br]The son of a millwright, Singer was employed as an unskilled labourer at the age of 12, but later gained wide experience as a travelling machinist. He also found employment as an actor. On 16 May 1839, while living at Lockport, Illinois, he obtained his first patent for a rock-drilling machine, but he soon squandered the money he made. Then in 1849, while at Pittsburgh, he secured a patent for a wood-and metal-carving machine that he had begun five years previously; however, a boiler explosion in the factory destroyed his machine and left him penniless.Near the end of 1850 Singer was engaged to redesign the Lerow \& Blodgett sewing machine at the Boston shop of Orson C.Phelps, where the machine was being repaired. He built an improved version in eleven days that was sufficiently different for him to patent on 12 August 1851. He formed a partnership with Phelps and G.B. Zieber and they began to market the invention. Singer soon purchased Phelps's interest, although Phelps continued to manufacture the machines. Then Edward Clark acquired a one-third interest and with Singer bought out Zieber. These two, with dark's flair for promotion and marketing, began to create a company which eventually would become the largest manufacturer of sewing machines exported worldwide, with subsidiary factories in England.However, first Singer had to defend his patent, which was challenged by an earlier Boston inventor, Elias Howe. Although after a long lawsuit Singer had to pay royalties, it was the Singer machine which eventually captured the market because it could do continuous stitching. In 1856 the Great Sewing Machine Combination, the first important pooling arrangement in American history, was formed to share the various patents so that machines could be built without infringements and manufacture could be expanded without fear of litigation. Singer contributed his monopoly on the needle-bar cam with his 1851 patent. He secured twenty additional patents, so that his original straight-needle vertical design for lock-stitching eventually included such refinements as a continuous wheel-feed, yielding presser-foot, and improved cam for moving the needle-bar. A new model, introduced in 1856, was the first to be intended solely for use in the home.Initially Phelps made all the machines for Singer. Then a works was established in New York where the parts were assembled by skilled workers through filing and fitting. Each machine was therefore a "one-off" but Singer machines were always advertised as the best on the market and sold at correspondingly high prices. Gradually, more specialized machine tools were acquired, but it was not until long after Singer had retired to Europe in 1863 that Clark made the change to mass production. Sales of machines numbered 810 in 1853 and 21,000 ten years later.[br]Bibliography12 August 1851, US patent no. 8,294 (sewing machine)Further ReadingBiographies and obituaries have appeared in Appleton's Cyclopedia of America, Vol. V; Dictionary of American Biography, Vol XVII; New York Times 25 July 1875; Scientific American (1875) 33; and National Cyclopaedia of American Biography.D.A.Hounshell, 1984, From the American System to Mass Production 1800–1932.
