5 Herbert, Edward Geisler
[br]b. 23 March 1869 Dedham, near Colchester, Essex, Englandd. 9 February 1938 West Didsbury, Manchester, England[br]English engineer, inventor of the Rapidor saw and the Pendulum Hardness Tester, and pioneer of cutting tool research.[br]Edward Geisler Herbert was educated at Nottingham High School in 1876–87, and at University College, London, in 1887–90, graduating with a BSc in Physics in 1889 and remaining for a further year to take an engineering course. He began his career as a premium apprentice at the Nottingham works of Messrs James Hill \& Co, manufacturers of lace machinery. In 1892 he became a partner with Charles Richardson in the firm of Richardson \& Herbert, electrical engineers in Manchester, and when this partnership was dissolved in 1895 he carried on the business in his own name and began to produce machine tools. He remained as Managing Director of this firm, reconstituted in 1902 as a limited liability company styled Edward G.Herbert Ltd, until his retirement in 1928. He was joined by Charles Fletcher (1868–1930), who as joint Managing Director contributed greatly to the commercial success of the firm, which specialized in the manufacture of small machine tools and testing machinery.Around 1900 Herbert had discovered that hacksaw machines cut very much quicker when only a few teeth are in operation, and in 1902 he patented a machine which utilized this concept by automatically changing the angle of incidence of the blade as cutting proceeded. These saws were commercially successful, but by 1912, when his original patents were approaching expiry, Herbert and Fletcher began to develop improved methods of applying the rapid-saw concept. From this work the well-known Rapidor and Manchester saws emerged soon after the First World War. A file-testing machine invented by Herbert before the war made an autographic record of the life and performance of the file and brought him into close contact with the file and tool steel manufacturers of Sheffield. A tool-steel testing machine, working like a lathe, was introduced when high-speed steel had just come into general use, and Herbert became a prominent member of the Cutting Tools Research Committee of the Institution of Mechanical Engineers in 1919, carrying out many investigations for that body and compiling four of its Reports published between 1927 and 1933. He was the first to conceive the idea of the "tool-work" thermocouple which allowed cutting tool temperatures to be accurately measured. For this advance he was awarded the Thomas Hawksley Gold Medal of the Institution in 1926.His best-known invention was the Pendulum Hardness Tester, introduced in 1923. This used a spherical indentor, which was rolled over, rather than being pushed into, the surface being examined, by a small, heavy, inverted pendulum. The period of oscillation of this pendulum provided a sensitive measurement of the specimen's hardness. Following this work Herbert introduced his "Cloudburst" surface hardening process, in which hardened steel engineering components were bombarded by steel balls moving at random in all directions at very high velocities like gaseous molecules. This treatment superhardened the surface of the components, improved their resistance to abrasion, and revealed any surface defects. After bombardment the hardness of the superficially hardened layers increased slowly and spontaneously by a room-temperature ageing process. After his retirement in 1928 Herbert devoted himself to a detailed study of the influence of intense magnetic fields on the hardening of steels.Herbert was a member of several learned societies, including the Manchester Association of Engineers, the Institute of Metals, the American Society of Mechanical Engineers and the Institution of Mechanical Engineers. He retained a seat on the Board of his company from his retirement until the end of his life.[br]Principal Honours and DistinctionsManchester Association of Engineers Butterworth Gold Medal 1923.

6 Charpy, Augustin Georges Albert
SUBJECT AREA: Metallurgy[br]b. 1 September 1865 Ouillins, Rhône, Franced. 25 November 1945 Paris, France[br]French metallurgist, originator of the Charpy pendulum impact method of testing metals.[br]After graduating in chemistry from the Ecole Polytechnique in 1887, Charpy continued to work there on the physical chemistry of solutions for his doctorate. He joined the Laboratoire d'Artillerie de la Marine in 1892 and began to study the structure and mechanical properties of various steels in relation to their previous heat treatment. His first memoir, on the mechanical properties of steels quenched from various temperatures, was published in 1892 on the advice of Henri Le Chatelier. He joined the Compagnie de Chatillon Commentry Fourchamboult et Decazeville at their steelworks in Imphy in 1898, shortly after the discovery of Invar by G.E. Guillaume. Most of the alloys required for this investigation had been prepared at Imphy, and their laboratories were therefore well equipped with sensitive and refined dilatometric facilities. Charpy and his colleague L.Grenet utilized this technique in many of their earlier investigations, which were largely concerned with the transformation points of steel. He began to study the magnetic characteristics of silicon steels in 1902, shortly after their use as transformer laminations had first been proposed by Hadfield and his colleagues in 1900. Charpy was the first to show that the magnetic hysteresis of these alloys decreased rapidly as their grain size increased.The first details of Charpy's pendulum impact testing machine were published in 1901, about two years before Izod read his paper to the British Association. As with Izod's machine, the energy of fracture was measured by the retardation of the pendulum. Charpy's test pieces, however, unlike those of Izod, were in the form of centrally notched beams, freely supported at each end against rigid anvils. This arrangement, it was believed, transmitted less energy to the frame of the machine and allowed the energy of fracture to be more accurately measured. In practice, however, the blow of the pendulum in the Charpy test caused visible distortion in the specimen as a whole. Both tests were still widely used in the 1990s.In 1920 Charpy left Imphy to become Director-General of the Compagnie des Aciéries de la Marine et Homecourt. After his election to the Académie des Sciences in 1918, he came to be associated with Floris Osmond and Henri Le Chatelier as one of the founders of the "French School of Physical Metallurgy". Around the turn of the century he had contributed much to the development of the metallurgical microscope and had helped to introduce the Chatelier thermocouple into the laboratory and to industry. He also popularized the use of platinum-wound resistance furnaces for laboratory purposes. After 1920 his industrial responsibilities increased greatly, although he continued to devote much of his time to teaching at the Ecole Supérieure des Mines in Paris, and at the Ecole Polytechnique. His first book, Leçons de Chimie (1892, Paris), was written at the beginning of his career, in association with H.Gautier. His last, Notions élémentaires de sidérurgie (1946, Paris), with P.Pingault as co-author, was published posthumously.[br]BibliographyCharpy published important metallurgical papers in Comptes rendus… Académie des Sciences, Paris.Further ReadingR.Barthélémy, 1947, "Notice sur la vie et l'oeuvre de Georges Charpy", Notices et discours, Académie des Sciences, Paris (June).M.Caullery, 1945, "Annonce du décès de M.G.
