7 Garforth, William Edward
SUBJECT AREA: Mining and extraction technology[br]b. 1845 Dukinfield, Cheshire, Englandd. 1 October 1921 Pontefract, Yorkshire, England[br]English colliery manager, pioneer in machine-holing and the safety of mines.[br]After Menzies conceived his idea of breaking off coal with machines in 1761, many inventors subsequently followed his proposals through into the practice of underground working. More than one century later, Garforth became one of the principal pioneers of machine-holing combined with the longwall method of working in order to reduce production costs and increase the yield of coal. Having been appointed agent to Pope \& Pearson's Collieries, West Yorkshire, in 1879, of which company he later became Managing Director and Chairman, he gathered a great deal of experience with different methods of cutting coal. The first disc machine was exhibited in London as early as 1851, and ten years later a pick machine was invented. In 1893 he introduced an improved type of deep undercutting machine, his "diamond" disc coal-cutter, driven by compressed air, which also became popular on the European continent.Besides the considerable economic advantages it created, the use of machinery for mining coal increased the safety of working in hard and thin seams. The improvement of safety in mining technology was always his primary concern, and as a result of his inventions and his many publications he became the leading figure in the British coal mining industry at the beginning of the twentieth century; safety lamps still carry his name. In 1885 he invented a firedamp detector, and following a severe explosion in 1886 he concentrated on coal-dust experiments. From the information he obtained of the effect of stone-dust on a coal-dust explosion he proposed the stone-dust remedy to prevent explosions of coal-dust. As a result of discussions which lasted for decades and after he had been entrusted with the job of conducting the British coal-dust experiments, in 1921 an Act made it compulsory in all mines which were not naturally wet throughout to treat all roads with incombustible dust so as to ensure that the dust always consisted of a mixture containing not more than 50 per cent combustible matter. In 1901 Garforth erected a surface gallery which represented the damaged roadways of a mine and could be filled with noxious fumes to test self-contained breathing apparata. This gallery formed the model from which all the rescue-stations existing nowadays have been developed.[br]Principal Honours and DistinctionsKnighted 1914.

8 Menzies, Michael
[br]b. end of the seventeenth century Lanarkshire, Scotland (?)d. 13 December 1766 Edinburgh, Scotland[br]Scottish inventor and lawyer.[br]Menzies was admitted as a member of the Faculty of Advocates on 31 January 1719. It is evident from his applications for patents that he was more concerned with inventions than the law, however. He took out his first patent in 1734 for a threshing machine in which a number of flails were attached to a horizontal axis, which was moved rapidly forwards and backwards through half a revolution, essentially imitating the action of an ordinary flail. The grain to be threshed was placed on either side.Though not a practical success, Menzies's invention seems to have been the first for the mechanical threshing of grain. His idea of imitating non-mechanized action also influenced his invention of a coal cutter, for which he took out a patent in 1761 and which copied miners' tools for obtaining coal. He proposed to carry heavy chains down the pit so that they could be used to give motion to iron picks, saws or other chains with cutting implements. The chains could be set into motion by a steam-engine, by water-or windmills, or by horses gins. Although it is quite obvious that this apparatus could not work, Menzies was the first to have thought of mechanizing coal production in the style that was in use in the late twentieth century. Subsequent to Menzies's proposal, many inventors at varying intervals followed this direction until the problem was finally solved one century later by, among others, W.E. Garforth.Menzies had successfully used the power of a steam-engine on the Wear eight years beforehand, when he obtained a patent for raising coal. According to his device a descending bucket filled with water raised a basket of coals, while a steam-engine pumped the water back to the surface; the balance-tub system, in various forms, quickly spread to other coalfields. Menzies's patent from 1750 for improved methods of carrying the coals from the coalface to the pit-shaft had also been of considerable influence: this device employed self-acting inclined planes, whereon the descending loaded wagons hauled up the empty ones.[br]Further ReadingThe article entitled "Michael Menzies" in the Dictionary of National Biography neglects Menzies's inventions for mining. A comprehensive evaluation of his influence on coal cutting is given in the introductory chapter of S.F.Walker, 1902, Coal-Cutting byMachinery, London.WK -
