121 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. "Torsional hysteresis of mild steel", Proceedings of the Royal Society A93:313.1918. with F.C.Lea, "Curved beams", Proceedings of the Royal Society A95:1. 1930, "Effects of rapidly acting stress", Proceedings of the Institution of MechanicalEngineers 119:1,273.RTS -
122 Kirk, Alexander Carnegie
[br]b. c.1830 Barry, Angus, Scotlandd. 5 October 1892 Glasgow, Scotland[br]Scottish marine engineer, advocate of multiple-expansion in steam reciprocating engines.[br]Kirk was a son of the manse, and after attending school at Arbroath he proceeded to Edinburgh University. Following graduation he served an apprenticeship at the Vulcan Foundry, Glasgow, before serving first as Chief Draughtsman with the Thames shipbuilders and engineers Maudslay Sons \& Field, and later as Engineer of Paraffin Young's Works at Bathgate and West Calder in Lothian. He was credited with the inventions of many ingenious appliances and techniques for improving production in these two establishments. About 1866 Kirk returned to Glasgow as Manager of the Cranstonhill Engine Works, then moved to Elder's Shipyard (later known as the Fairfield Company) as Engineering Manager. There he made history in producing the world's first triple-expansion engines for the single-screw steamship Propontis in 1874. That decade was to confirm the Clyde's leading role as shipbuilders to the world and to establish the iron ship with efficient reciprocating machinery as the workhorse of the British Merchant Marine. Upon the death of the great Clyde shipbuilder Robert Napier in 1876, Kirk and others took over as partners in the shipbuilding yard and engine shops of Robert Napier \& Sons. There in 1881 they built a ship that is acknowledged as one of the masterpieces of British shipbuilding: the SS Aberdeen for George Thompson's Aberdeen Line to the Far East. In this ship the fullest advantage was taken of high steam temperatures and pressures, which were expanded progressively in a three-cylinder configuration. The Aberdeen, in its many voyages from London to China and Japan, was to prove the efficiency of these engines that had been so carefully designed in Glasgow. In the following years Dr Kirk (he has always been known as Doctor, although his honorary LLD was only awarded by Glasgow University in 1888) persuaded the Admiralty and several shipping companies to accept not only triple-expansion machinery but also the use of mild steel in ship construction. The successful SS Parisian, built for the Allan Line of Glasgow, was one of these pioneer ships.[br]Principal Honours and DistinctionsFellow of the Royal Society of Edinburgh.FMWBiographical history of technology > Kirk, Alexander Carnegie
