1 Guest, James John
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 24 July 1866 Handsworth, Birmingham, Englandd. 11 June 1956 Virginia Water, Surrey, England[br]English mechanical engineer, engineering teacher and researcher.[br]James John Guest was educated at Marlborough in 1880–4 and at Trinity College, Cambridge, graduating as fifth wrangler in 1888. He received practical training in several workshops and spent two years in postgraduate work at the Engineering Department of Cambridge University. After working as a draughtsman in the machine-tool, hydraulic and crane departments of Tangyes Ltd at Birmingham, he was appointed in 1896 Assistant Professor of Engineering at McGill University in Canada. After a short time he moved to the Polytechnic Institute at Worcester, Massachusetts, where he was for three years Professor of Mechanical Engineering and Head of the Engineering Department. In 1899 he returned to Britain and set up as a consulting engineer in Birmingham, being a partner in James J.Guest \& Co. For the next fifteen years he combined this work with research on grinding phenomena. He also developed a theory of grinding which he first published in a paper at the British Association for the Advancement of Science in 1914 and elaborated in a paper to the Institution of Mechanical Engineers and in his book Grinding Machinery (1915). During the First World War, in 1916–17, he was in charge of inspection in the Staffordshire and Shropshire Area, Ministry of Munitions. In 1917 he returned to teaching as Reader in Graphics and Structural Engineering at University College London. His final appointment was about 1923 as Professor of Mechanical and Electrical Engineering, Artillery College, Woolwich, which later became the Military College of Science.He carried out research on the strength of materials and contributed many articles on the subject to the technical press. He originated Guest's Law for a criterion of failure of materials under combined stresses, first published in 1900. He was a Member of the Institution of Mechanical Engineers in 1900–6 and from 1919 and contributed to their proceedings in many discussions and two major papers.[br]BibliographyOf many publications by Guest, the most important are: 1900, "Ductile materials under combined stress", Proceedings of the Physical Society 17:202.1915, Grinding Machinery, London.1915, "Theory of grinding, with reference to the selection of speeds in plain and internal work", Proceedings of the Institution of Mechanical Engineers 89:543.1917.

2 Austin, John
SUBJECT AREA: Textiles[br]fl. 1789 Scotland[br]Scottish contributor to the early development of the power loom.[br]On 6 April 1789 John Austin wrote to James Watt, seeking advice about patenting "a weaving loom I have invented to go by the hand, horse, water or any other constant power, to comb, brush, or dress the yarn at the same time as it is weaving \& by which one man will do the work of three and make superior work to what can be done by the common loom" (Boulton \& Watt Collection, Birmingham, James Watt Papers, JW/22). Watt replied that "there is a Clergyman by the name of Cartwright at Doncaster who has a patent for a similar contrivance" (Boulton \& Watt Collection, Birmingham, Letter Book 1, 15 April 1789). Watt pointed out that there was a large manufactory running at Doncaster and something of the same kind at Manchester with working power looms. Presumably, this reply deterred Austin from taking out a patent. However, some members of the Glasgow Chamber of Commerce continued developing the loom, and in 1798 one that was tried at the spinning mill of J.Monteith, of Pollokshaws, near Glasgow, answered the purpose so well that a building was erected and thirty of the looms were installed. Later, in 1800, this number was increased to 200, all of which were driven by a steam engine, and it was stated that one weaver and a boy could tend from three to five of these looms.Austin's loom was worked by eccentrics, or cams. There was one cam on each side with "a sudden beak or projection" that drove the levers connected to the picking pegs, while other cams worked the heddles and drove the reed. The loom was also fitted with a weft stop motion and could produce more cloth than a hand loom, and worked at about sixty picks per minute. The pivoting of the slay at the bottom allowed the loom to be much more compact than previous ones.[br]Further ReadingA.Rees, 1819, The Cyclopaedia: or Universal Dictionary of Arts, Sciences and Literature, London.R.Guest, 1823, A Compendius History of the Cotton Manufacture, Manchester.A.P.Usher, 1958, A History of Mechanical Inventions.W.English, 1969, The Textile Industry, London.R.L.Hills, 1970, Power in the Industrial Revolution, Manchester.See also: Cartwright, Revd EdmundRLH -

4 Highs, Thomas
SUBJECT AREA: Textiles[br]fl. 1760s England[br]English reedmaker who claimed to have invented both the spinning jenny and the waterframe.[br]The claims of Highs to have invented both the spinning jenny and the waterframe have been dismissed by most historians. Thomas Highs was a reedmaker of Leigh, Lancashire. In about 1763 he had as a neighbour John Kay, the clockmaker from Warrington, whom he employed to help him construct his machines. During this period they were engaged in making a spinning jenny, but after several months of toil, in a fit of despondency, they threw the machine through the attic window. Highs persevered, however, and made a jenny that could spin six threads. The comparatively sophisticated arrangements for drawing and twisting at the same time, as depicted by Guest (1823), suggest that this machine came after the one invented by James Hargreaves. Guest claims that Highs made this machine between 1764 and 1766 and in the following two years constructed another, in which the spindles were placed in a circle. In 1771 Highs moved to Manchester, where he constructed a double jenny that was displayed at the Manchester Exchange, and received a subscription of £200 from the cotton manufacturers. However, all this occurred after Hargreaves had constructed his jenny. In the trial of Arkwright's patent during 1781, Highs gave evidence. He was recalled from Ireland, where he had been superintending the building of cotton-spinning machinery for Baron Hamilton's newly erected mill at Balbriggan, north of Dublin. Then in 1785, during the next trial of Arkwright's patent, Highs claimed that in 1767 he had made rollers for drawing out the cotton before spinning. This would have been for a different type of spinning machine, similar to the one later constructed by Arkwright. Highs was helped by John Kay and it was these rollers that Kay subsequently built for Arkwright. If the drawing shown by Guest is correct, then Highs was working on the wrong principles because his rollers were spaced too far apart and were not held together by weights, with the result that the twist would have passed into the drafting zone, producing uneven drawing.[br]Further ReadingR.Guest, 1823, A Compendious History of the Cotton-Manufacture: With a Disproval of the Claim of Sir Richard Arkwright to the Invention of its Ingenious Machinery, Manchester (Highs's claim for the invention of his spinning machines).R.S.Fitton, 1989, The Arkwrights, Spinners of Fortune, Manchester (an examination of Highs's claims).R.L.Hills, 1970, Power in the Industrial Revolution, Manchester (discusses the technical problems of the invention).RLH
