9 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.

12 Polhem, Christopher
SUBJECT AREA: Mining and extraction technology[br]b. 18 December 1661 Tingstade, Gotland, Sweden d. 1751[br]Swedish engineer and inventor.[br]He was the eldest son of Wolf Christopher Polhamma, a merchant. The father died in 1669 and the son was sent by his stepfather to an uncle in Stockholm who found him a place in the Deutsche Rechenschule. After the death of his uncle, he was forced to find employment, which he did with the Biorenklou family near Uppsala where he eventually became a kind of estate bailiff. It was during this period that he started to work with a lathe, a forge and at carpentry, displaying great technical ability. He realized that without further education he had little chance of making anything of his life, and accordingly, in 1687, he registered at the University of Uppsala where he studied astronomy and mathematics, remaining there for three years. He also repaired two astronomical pendulum clocks as well as the decrepit medieval clock in the cathedral. After a year's work he had this clock running properly: this was his breakthrough. He was summoned to Stockholm where the King awarded him a salary of 500 dalers a year as an encouragement to further efforts. Around this time, one of increasing mechanization and when mining was Sweden's principal industry, Pohlem made a model of a hoist frame for mines and the Mines Authority encouraged him to develop his ideas. In 1693 Polhem completed the Blankstot hoist at the Stora Kopparberg mine, which attracted great interest on the European continent.From 1694 to 1696 Polhem toured factories, mills and mines abroad in Germany, Holland, England and France, studying machinery of all kinds and meeting many foreign engineers. In 1698 he was appointed Director of Mining Engineering in Sweden, and in 1700 he became Master of Construction in the Falu Mine. He installed the Karl XII hoist there, powered by moving beams from a distant water-wheel. His plan of 1697 for all the machinery at the Falu mine to be driven by three large and remote water-wheels was never completed.In 1707 he was invited by the Elector of Hanover to visit the mines in the Harz district, where he successfully explained many of his ideas which were adopted by the local engineers. In 1700, in conjunction with Gabriel Stierncrona, he founded the Stiersunds Bruk at Husby in Southern Dalarna, a factory for the mass production of metal goods in iron, steel and bronze. Simple articles such as pans, trays, bowls, knives, scissors and mirrors were made there, together with the more sophisticated Polhem lock and the Stiersunds clock. Production was based on water power. Gear cutting for the clocks, shaping hammers for plates, file cutting and many other operations were all water powered, as was a roller mill for the sheet metal used in the factory. He also designed textile machinery such as stocking looms and spinning frames and machines for the manufacture of ribbons and other things.In many of his ideas Polhem was in advance of his time and Swedish country society was unable to absorb them. This was largely the reason for the Stiersund project being only a partial success. Polhem, too, was of a disputatious nature, self-opinionated almost to the point of conceit. He was a prolific writer, leaving over 20,000 pages of manuscript notes, drafts, essays on a wide range of subjects, which included building, brick-making, barrels, wheel-making, bell-casting, organ-building, methods of stopping a horse from bolting and a curious tap "to prevent serving maids from sneaking wine from the cask", the construction of ploughs and threshing machines. His major work, Kort Berattelse om de Fornamsta Mechaniska Inventioner (A Brief Account of the Most Famous Inventions), was printed in 1729 and is the main source of knowledge about his technological work. He is also known for his "mechanical alphabet", a collection of some eighty wooden models of mechanisms for educational purposes. It is in the National Museum of Science and Technology in Stockholm.[br]Bibliography1729, Kort Berattelse om de Fornamsta Mechaniska Inventioner (A Brief Account of the Most Famous Inventions).Further Reading1985, Christopher Polhem, 1661–1751, TheSwedish Daedalus' (catalogue of a travelling exhibition from the Swedish Institute in association with the National Museum of Science and Technology), Stockholm.IMcN
