SUBJECT AREA: Canals[br]b. 7 (?) August 1779 Lambeth, London, Englandd. 1 February 1836 Frant, Sussex, England[br]English Engineer-in-Charge of the construction of the Rideau Canal, linking the St Lawrence and Ottawa Rivers in Canada.[br]Admitted in 1797 as a Gentleman Cadet in the Royal Military Academy at Woolwich, By was commissioned on 1 August 1799 as a second lieutenant in the Royal Artillery, but was soon transferred to the Royal Engineers. Posted to Plymouth upon the development of the fortifications, he was further posted to Canada, arriving there in August 1802.In 1803 By was engaged in canal work, assisting Captain Bruyères in the construction of a short canal (1,500 ft (460 m) long) at the Cascades on the Grand, now the Ottawa, River. In 1805 he was back at the Cascades repairing ice damage caused during the previous winter. He was promoted Captain in 1809. Meanwhile he worked on the fortifications of Quebec and in 1806–7 he built a scale model of the Citadel, which is now in the National War Museum of Canada. He returned to England in 1810 and served in Portugal in 1811. Back in England at the end of the year, he was appointed Royal Engineer Officer in charge at the Waltham Abbey Gunpowder Works on 1 January 1812 and later planned the new Small Arms Factory at Enfield; both works were on the navigable River Lee.In the post-Napoleonic period Major By, as he then was, retired on half-pay but was promoted to Lieu tenant-Colonel on 2 December 1824. Eighteen months later, in March 1826, he returned to Canada on active duty to build the Rideau Canal. This was John By's greatest work. It was conceived after the American war of 1812–14 as a connection for vessels to reach Kingston and the Great Lakes from Montreal while avoiding possible attack from the United States forces. Ships would pass up the Ottawa River using the already-constructed locks and bypass channels and then travel via a new canal cut through virgin forest southwards to the St Lawrence at Kingston. By based his operational headquarters at the Ottawa River end of the new works and in a forest clearing he established a small settlement. Because of the regard in which By was held, this settlement became known as By town. In 1855, long after By's death, the settlement was designated by Queen Victoria as capital of United Canada (which was to become a self-governing Dominion in 1867) and renamed Ottawa; as a result of the presence of the national government, the growth of the town accelerated greatly.Between 1826–7 and 1832 the Rideau Canal was constructed. It included the massive engineering works of Jones Falls Dam (62 ft 6 in. (19 m) high) and 47 locks. By exercised an almost paternal care over those employed under his direction. The canal was completed in June 1832 at a cost of £800,000. By was summoned back to London to face virulent and unjust criticism from the Treasury. He was honoured in Canada but vilified by the British Government.[br]Further ReadingR.F.Leggett, 1982, John By, Historical Society of Canada.—1976, Canals of Canada, Newton Abbot: David \& Charles.—1972, Rideau Waterway, Toronto: University of Toronto Press.Bernard Pothier, 1978, "The Quebec Model", Canadian War Museum Paper 9, Ottawa: National Museums of Canada.JHBBiographical history of technology > By, Lieutenant-Colonel John

62 Chappe, Claude
SUBJECT AREA: Telecommunications[br]b. 25 December 1763 Brulon, Franced. 23 January 1805 Paris, France[br]French engineer who invented the semaphore visual telegraph.[br]Chappe began his studies at the Collège de Joyeuse, Rouen, and completed them at La Flèche. He was educated for the church with the intention of becoming an Abbé Commendataire, but this title did not in fact require him to perform any religious duties. He became interested in natural science and amongst other activities he carried out experiments with electrically charged soap bubbles.When the bénéfice was suppressed in 1781 he returned home and began to devise a system of telegraphic communication. With the help of his three brothers, particularly Abraham, and using an old idea, in 1790 he made a visual telegraph with suspended pendulums to relay coded messages over a distance of half a kilometre. Despite public suspicion and opposition, he presented the idea to the Assemblée Nationale on 22 May 1792. No doubt due to the influence of his brother, Ignace, a member of the Assemblée Nationale, the idea was favourably received, and on 1 April 1793 it was referred to the National Convention as being of military importance. As a result, Chappe was given the title of Telegraphy Engineer and commissioned to construct a semaphore (Gk. bearing a sign) link between Paris and Lille, a distance of some 240 km (150 miles), using twenty-two towers. Each station contained two telescopes for observing the adjacent towers, and each semaphore consisted of a central beam supporting two arms, whose positions gave nearly two hundred possible arrangements. Hence, by using a code book as a form of lookup table, Chappe was able to devise a code of over 8,000 words. The success of the system for communication during subsequent military conflicts resulted in him being commissioned to extend it with further links, a work that was continued by his brothers after his suicide during a period of illness and depression. Providing as it did an effective message speed of several thousand kilometres per hour, the system remained in use until the mid-nineteenth century, by which time the electric telegraph had become well established.[br]Further ReadingR.Appleyard, 1930, Pioneers of Electrical Communication.International Telecommunications Union, 1965, From Semaphore to Satellite, Geneva.See also: Morse, Samuel Finley BreezeKF -
63 Cros, Charles
SUBJECT AREA: Photography, film and optics[br]b. 1842 Franced. 1888[br]French doctor, painter and man of letters who pioneered research into colour photography.[br]A man of considerable intellect, Cros occupied himself with studies of topics as diverse as Sanskrit and the synthesis of precious stones. He was in particular interested in the possibility of colour photography, and deposited an account of his theories in a sealed envelope with the Académie des Sciences on 2 December 1867, with instructions that it should be opened in 1876. Learning of a forthcoming presentation on colour photography by Ducos du Hauron at the Société Française de Photographie, he arranged for the contents of his communication to be published on 25 February 1869 in Les Mondes. At the Société's meeting on 7 May 1869, Cros's letter was read and samples of colour photography from Ducos du Hauron were shown. Both had arrived at similar conclusions: that colour photography was possible with the analysis of colours using negatives exposed through red, green and blue filters, as demonstrated by Clerk Maxwell in 1861. These records could be reproduced by combining positive images produced in blue-green, magenta and yellow pigments or dyes. Cros and Ducos du Hauron had discovered the principle of subtractive colour photography, which is used in the late twentieth century. In 1878 Cros designed the Chromometre, a device for measuring colours by mixing red, green and blue light, and described the device in a paper to the Société Française de Photographie on 10 January 1879. With suitable modification, the device could be used as a viewer for colour photographs, combining red, green and blue positives. In 1880 he patented the principle of imbibition printing, in which dye taken up by a gelatine relief image could be transferred to another support. This principle, which he called hydrotypie, readily made possible the production of three-colour subtractive photographic prints.[br]Further ReadingJ.S.Friedman, 1944, History of Colour Photography, Boston.

64 Holt, Benjamin
SUBJECT AREA: Agricultural and food technology[br]b. 1 January 1849 Concord, New Hampshire, USAd. 5 December 1924 Stockton, California, USA[br]American machinery manufacturer responsible for the development of the Caterpillar tractor and for early developments in combine harvesters.[br]In 1864 Charles Henry Holt led three other brothers to California in response to the gold rush. In 1868 he founded C.H.Holt \& Co. in San Francisco with the help of his brothers Williams and Ames. The company dealt in timber as well as wagon and carriage materials, as did the business they had left behind in Concord in the care of their youngest brother, Benjamin. In 1883 Benjamin joined the others in California and together they formed the Stockton Wheel Company with offices in San Francisco and Stockton. The brothers recognized the potential of combine harvesters and purchased a number of patents, enlarged their works and began to experiment. Their first combine was produced in 1886, and worked for forty-six days that year. With the stimulus of Benjamin Holt the company produced the first hillside combine in 1891 and introduced the concept of belt drive. The Holt harvesting machine produced in 1904 was the first to use an auxiliary gas engine. By 1889 Benjamin was sole family executive. In 1890 the company produced its first traction engine. He began experimenting with track-laying machines, building his first in 1904. It was this machine which earned the nickname "Caterpillar", which has remained the company trade name to the present day. In 1906 thecompany produced its first gasoline-engined Caterpillar, and the first production model was introduced two years later. The development of Caterpillar tractors had a significant impact on the transport potential of the Allies during the First World War, and the Holt production of track-laying traction engines was of immense importance to the supply of the armed forces. In 1918 Benjamin Holt was still actively involved in the company, but he died in Stockton in 1920.[br]Further ReadingW.A.Payne (ed.), 1982, Benjamin Holt: The Story of the Caterpillar Tractor, Stockton, Calif: University of the Pacific (provides an illustrated account of the life of Holt and the company he formed).R.Jones, "Benjamin Holt and the Caterpillar tractor", Vintage Tractor Magazine 1st special vol.AP -
65 Leblanc, Nicolas
SUBJECT AREA: Chemical technology[br]b. 6 December 1742 Ivey-le-Pré, Franced. 16 January 1806 Paris, France[br]French chemist, inventor of the Leblanc process for the manufacture of soda.[br]Orphaned at an early age, Leblanc was sent by his guardian, a doctor, to study medicine at the Ecole de Chirurgie in Paris. Around 1780 he entered the service of the Duke of Orléans as Surgeon. There he was able to pursue his interest in chemistry by carrying out research, particularly into crystallization; this bore fruit in a paper to the Royal Academy of Sciences in 1786, published in 1812 as a separate work entitled Crystallotechnie. At that time there was much concern that supplies of natural soda were becoming insufficient to meet the increasing demands of various industries, textile above all. In 1775 the Academy offered a prize of 2,400 livres for a means of manufacturing soda from sea salt. Several chemists studied the problem, but the prize was never awarded. However, in 1789 Leblanc reported in the Journal de physique for 1789 that he had devised a process, and he applied to his patron for support. The Duke had the process subjected to tests, and when these proved favourable he, with Leblanc and the referee, formed a company in February 1790 to exploit it. A patent was granted in 1791 and, with the manufacture of a vital substance at low cost based on a raw material, salt in unlimited supply, a bright prospect seemed to open out for Leblanc. The salt was treated with sulphuric acid to form salt-cake (sodium sulphate), which was then rotated with coal and limestone to form a substance from which the soda was extracted with water followed by evaporation. Hydrochloric acid was a valuable by-product, from which could be made calcium chloride, widely used in the textile and paper industries. The factory worked until 1793, but did not achieve regular production, and then disaster struck: Leblanc's principal patron, the Duke of Orléans, perished under the guillotine in the reign of terror; the factory was sequestered by the Revolutionary government and the agreement was revoked. Leblanc laboured in vain to secure adequate compensation. Eventually a grant was made towards the cost of restoring the factory, but it was quite inadequate, and in despair, Leblanc shot himself. However, his process proved to be one of the greatest inventions in the chemical industry, and was taken up in other countries and remained the leading process for the production of soda for a century. In 1855 his family tried again to vindicate his name and achieve compensation, this time with success.[br]Further ReadingA.A.Leblanc, 1884, Nicolas Leblanc, sa vie, ses travaux et l'histoire de la soude artificielle, Paris (the standard biography, by his grandson).For more critical studies, see: C.C.Gillispie, 1957, "The discovery of the Leblanc process", Isis 48:152–70; J.G.Smith, 1970, "Studies in certain chemical industries in revolutionary and Napoleonic France", unpublished PhD thesis, Leeds University.LRD -
66 Owens, Michael Joseph
[br]b. 1 January 1859 Mason County, Virginia, USAd. 27 December 1923 Toledo, Ohio, USA[br]American inventor of the automatic glass bottle making machine.[br]To assist the finances of a coal miner's family, Owens entered a glassworks at Wheeling, Virginia, at the tender age of 10, stoking coal into the "glory hole" or furnace where glass was resoftened at various stages of the hand-forming process. By the age of 15 he had become a glassblower.In 1888 Owens moved to the glassworks of Edward Drummond Libbey at Toledo, Ohio, where within three months he was appointed Superintendent and, not long after, a branch manager. In 1893 Owens supervised the company's famous exhibit at the World's Columbian Exposition at Chicago. He had by then begun experiments that were to lead to the first automatic bottle-blowing machine. He first used a piston pump to suck molten glass into a mould, and then transferred the gathered glass over another mould into which the bottle was blown by reversing the pump. The first patents were taken out in 1895, followed by others incorporating improvements and culminating in the patent of 8 November 1904 for an essentially perfected machine. Eventually it was capable of producing four bottles a second, thus effecting a revolution in bottle making. Owens, with Libbey and others, set up the Owens Bottle Machine Company in 1903, which Owens himself managed from 1915 to 1919, becoming Vice-President from 1915 until his death. A plant was also established in Manchester in 1905.Besides this, Owens and Libbey first assisted Irving W.Colburn with his experiments on the continuous drawing of flat sheet glass and then in 1912 bought the patents, forming the Owens-Libbey Sheet Glass Company. In all, Owens was granted forty-five US patents, mainly relating to the manufacture and processing of glass. Owens's undoubted inventive genius was hampered by a lack of scientific knowledge, which he made good by judicious consultation.[br]Further Reading1923, Michael J.Owens (privately printed) (a series of memorial articles reprinted from various sources).G.S.Duncan, 1960, Bibliography of Glass, Sheffield: Society of Glass Manufacturers (cites references to Owens's papers and patents).LRD -
67 Pattinson, Hugh Lee
SUBJECT AREA: Metallurgy[br]b. 25 December 1796 Alston, Cumberland, Englandd. 11 November 1858 Scot's House, Gateshead, England[br]English inventor of a silver-extraction process.[br]Born into a Quaker family, he was educated at private schools; his studies included electricity and chemistry, with a bias towards metallurgy. Around 1821 Pattinson became Clerk and Assistant to Anthony Clapham, a soap-boiler of Newcastle upon Tyne. In 1825 he secured appointment as Assay Master to the lords of the manor of Alston. There he was able to pursue the subject of special interest to him, and in January 1829 he devised a method of separating silver from lead ore; however, he was prevented from developing it because of a lack of funds.Two years later he was appointed Manager of Wentworth Beaumont's lead-works. There he was able to continue his researches, which culminated in the patent of 1833 enshrining the invention by which he is best known: a new process for extracting silver from lead by skimming crystals of pure lead with a perforated ladle from the surface of the molten silver-bearing lead, contained in a succession of cast-iron pots. The molten metal was stirred as it cooled until one pot provided a metal containing 300 oz. of silver to the ton (8,370 g to the tonne). Until that time, it was unprofitable to extract silver from lead ores containing less than 8 oz. per ton (223 g per tonne), but the Pattinson process reduced that to 2–3 oz. (56–84 g per tonne), and it therefore won wide acceptance. Pattinson resigned his post and went into partnership to establish a chemical works near Gateshead. He was able to devise two further processes of importance, one an improved method of obtaining white lead and the other a new process for manufacturing magnesia alba, or basic carbonate of magnesium. Both processes were patented in 1841.Pattinson retired in 1858 and devoted himself to the study of astronomy, aided by a 7½ in. (19 cm) equatorial telescope that he had erected at his home at Scot's House.[br]Principal Honours and DistinctionsVice-President, British Association Chemical Section 1838.

68 Rittinger, Peter von
SUBJECT AREA: Mining and extraction technology[br]b. 23 January 1811 Neutitschein, Moravia (now Now Jicin, Czech Republic)d. 7 December 1872 Vienna, Austria[br]Austrian mining engineer, improver of the processing of minerals.[br]After studying law, philosophy and politics at the University of Olmutz (now Olomouc), in 1835 Rittinger became a fellow of the Mining Academy in Schemnitz (now Banská Štiavnica), Slovakia. In 1839, the year he finished at the academy, he published a book on perspective drawing. The following year, he became Inspector of Mills at the ore mines in Schemnitz, and in 1845 he was engaged in coal mining in Bohemia and Moravia. In 1849 he joined the mining administration at Joachimsthal (now Jáchymov), Bohemia. In these early years he contributed his first important innovations for the mining industry and thus fostered his career in the government's service. In 1850 he was called to Vienna to become a high-ranked officer in various ministries. He was responsible for the construction of buildings, pumping installations and all sorts of machinery in the mining industry; he reorganized the curricula of the mining schools, was responsible for the mint and became head of the department of mines, forests and salt-works in the Austrian empire.During all his years of public service, Rittinger continued his concern with technological innovations. He improved the processing of ores by introducing in 1844 the rotary washer and the box classifier, and later his continuously shaking concussion table which, having been exhibited at the Vienna World Fair of 1873, was soon adopted in other countries. He constructed water-column pumps, invented a differential shaft pump with hydraulic linkage to replace the heavy iron rods and worked on centrifugal pumps. He was one of the first to be concerned with the transfer of heat, and he developed a system of using exhaust steam for heating in salt-works. He kept his eye on current developments abroad, using his function as official Austrian commissioner to the world exhibitions, on which he published frequently as well as on other matters related to technology. With his systematic handbook on mineral processing, first published in 1867, he emphasized his international reputation in this specialized field of mining.[br]Principal Honours and DistinctionsKnighted 1863.

69 Short, Hugh Oswald
SUBJECT AREA: Aerospace[br]b. 16 January 1883 Derbyshire, Englandd. 4 December 1969 Haslemere, England[br]English co-founder, with his brothers Horace Short (1872–1917) and Eustace (1875–1932), of the first company to design and build aeroplanes in Britain.[br]Oswald Short trained as an engineer; he was largely self-taught but was assisted by his brothers Eustace and Horace. In 1898 Eustace and the young Oswald set up a balloon business, building their first balloon in 1901. Two years later they sold observation balloons to the Government of India, and further orders followed. Meanwhile, in 1906 Horace designed a high-altitude balloon with a spherical pressurized gondola, an idea later used by Auguste Piccard, in 1931. Horace, a strange genius with a dominating character, joined his younger brothers in 1908 to found Short Brothers. Their first design, based on the Wright Flyer, was a limited success, but No. 2 won a Daily Mail prize of £1,000. In the same year, 1909, the Wright brothers chose Shorts to build six of their new Model A biplanes. Still using the basic Wright layout, Horace designed the world's first twin-engined aeroplane to fly successfully: it had one engine forward of the pilot, and one aft. During the years before the First World War the Shorts turned to tractor biplanes and specialized in floatplanes for the Admiralty.Oswald established a seaplane factory at Rochester, Kent, during 1913–14, and an airship works at Cardington, Bedfordshire, in 1916. Short Brothers went on to build the rigid airship R 32, which was completed in 1919. Unfortunately, Horace died in 1917, which threw a greater responsibility onto Oswald, who became the main innovator. He introduced the use of aluminium alloys combined with a smooth "stressed-skin" construction (unlike Junkers, who used corrugated skins). His sleek biplane the Silver Streak flew in 1920, well ahead of its time, but official support was not forthcoming. Oswald Short struggled on, trying to introduce his all-metal construction, especially for flying boats. He eventually succeeded with the biplane Singapore, of 1926, which had an all-metal hull. The prototype was used by Sir Alan Cobham for his flight round Africa. Several successful all-metal flying boats followed, including the Empire flying boats (1936) and the ubiquitous Sunderland (1937). The Stirling bomber (1939) was derived from the Sunderland. The company was nationalized in 1942 and Oswald Short retired the following year.[br]Principal Honours and DistinctionsHonorary Fellow of the Royal Aeronautical Society.

70 Symington, William
SUBJECT AREA: Ports and shipping[br]b. 1764 Leadhills, Lanarkshire, Scotlandd. 22 March 1831 Wapping, London, England[br]Scottish pioneer of steam navigation.[br]Symington was the son of the Superintendent of the Mines Company in Lanarkshire, and attended the local school. When he was 22 years old he was sent by Gilbert Meason, Manager of the Wanlockhead mines, to Edinburgh University. In 1779 he was working on the assembly of a Watt engine as an apprentice to his brother, George, and in 1786 he started experiments to modify a Watt engine in order to avoid infringing the separate condenser patent. He sought a patent for his alternative, which was paid for by Meason. He constructed a model steam road carriage which was completed in 1786; it was shown in Edinburgh by Meason, attracting interest but inadequate financial support. It had a horizontal cylinder and was non-condensing. No full-sized engine was ever built but the model secured the interest of Patrick Miller, an Edinburgh banker, who ordered an engine from Symington to drive an experimental boat, 25 ft (7.6 m) long with a dual hull, which performed satisfactorily on Dalswinton Loch in 1788. In the following year Miller ordered a larger engine for a bigger boat which was tried on the Forth \& Clyde Canal in December 1789, the component parts having been made by the Carron Company. The engine worked perfectly but had the effect of breaking the paddle wheels. These were repaired and further trials were successful but Miller lost interest and his experiments lapsed. Symington devoted himself thereafter to building stationary engines. He built other engines for mine pumping at Sanquhar and Leadhills before going further afield. In all, he built over thirty engines, about half of them being rotary. In 1800–1 he designed the engine for a boat for Lord Dundas, the Charlotte Dundas; this was apparently the first boat of that name and sailed on both the Forth and Clyde rivers. A second Charlotte Dundas with a horizontal cylinder was to follow and first sailed in January 1803 for the Forth \& Clyde Canal Company. The speed of the boat was only 2 mph (3 km/h) and much was made by its detractors of the damage said to be caused to the canal banks by its wash. Lord Dundas declined to authorize payment of outstanding accounts; Symington received little reward for his efforts. He died in the house of his son-in-law, Dr Robert Bowie, in Wapping, amidst heated controversy about the true inventor of steam navigation.[br]Further ReadingW.S.Harvey and G.Downs-Rose, 1980, William Symington, Inventor and Engine- Builder, London: Mechanical Engineering Publications.IMcN -

[br]b. 14 December 1795 Huntingdon, New York, USAd. 12 January 1885 Rome, New York, USA[br]American pioneer of civil engineering and locomotive design.[br]Jervis assisted in the survey and construction of the Erie Canal, and by 1827 was Chief Engineer of the Delaware \& Hudson Canal and, linked with it, the Carbondale Railroad. He instructed Horatio Allen to go to England to purchase locomotives in 1828, and the locomotive Stourbridge Lion, built by J.U. Rastrick, was placed on the railway in 1829. It was the first full-size locomotive to run in America, but the track proved too weak for it to be used regularly. In 1830 Jervis became Chief Engineer to the Mohawk \& Hudson Rail Road, which was the first railway in New York State and was opened the following year. In 1832 the 4–2–0 locomotive Experiment was built to his plans by West Point Foundry: it was the first locomotive to have a leading bogie or truck. Jervis was subsequently associated with many other extensive canals and railways and pioneered economic analysis of engineering problems to enable, for example, the best choice to be made between two possible routes for a railroad.[br]Bibliography1861, Railway Property, New York.Further ReadingJ.H.White Jr, 1979, A History of the American Locomotive-Its Development: 1830–1880, New York: Dover Publications Inc.J.K.Finch, 1931, "John Bloomfield Jervis, civil engineer", Transactions of the Newcomen Society, 11.PJGRBiographical history of technology > Jervis, John Bloomfield

73 Wolf, Carl
SUBJECT AREA: Mining and extraction technology[br]b. 23 December 1838 Zwickau, Saxony, Germanyd. 30 January 1915 Zwickau, Saxony, Germany[br]German inventor of the most popular petroleum spirit safety lamp for use in mines.[br]From an old mining family in the Saxon coalfields, Wolf was aware from his youth of the urgent demand for a miner's lamp which would provide adequate light but not provoke firedamp explosions. While working as an engineer in Zwickau, Wolf spent his spare time conducting experiments for such a lamp. The basic concept of his invention was the principle that dangerous concentrations of methane and air would not explode within a small pipe; this had been established almost seventy years earlier by the English chemist Humphrey Davy. By combining and developing certain devices designed by earlier inventors, in 1883 Wolf produced a prototype with a glass cylinder, a primer fixed inside the lamp and a magnetic lock. Until the successful application of electric light, Wolfs invention was the safest and most popular mining safety lamp. Many earlier inventions had failed to address all the problems of lighting for mines; Davy's lamp, for example, would too quickly become sooty and hot. As Wolfs lamp burned petroleum spirit, at first it was mistrusted outside Saxony, but it successfully passed the safety tests in all the leading coal-producing countries at that time. As well as casting a safe, constant light, the appearance of the cap flame could indicate the concentration of fire-damp in the air, thus providing an additional safety measure. Wolfs first patent was soon followed by many others in several countries, and underwent many developments. In 1884 Heinrich Friemann, a merchant from Eisleben, invested capital in the new company of Friemann and Wolf, which became the leading producer of miners' safety lamps. By 1914 they had manufactured over one million lamps, and the company had branches in major mining districts worldwide.[br]Further ReadingF.Schwarz, 1914, Entwickelung und gegenwär-tiger Stand der Grubenbeleuchtung beim Steinkohlen-Bergbau, Gelsenkirchen (a systematic historical outline of safety lamp designs).WK -

76 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 -

80 Wells, Horace
SUBJECT AREA: Medical technology[br]b. 1815 Connecticut, USAd. 1848 Hartford, Connecticut, USA[br]American dentist, pioneer of dental extraction under nitrous oxide gas (laughing gas) anaesthesia.[br]Practising in Hartford, Connecticut, he was in partnership with W.T.G. Morton during 1842–3. Following experiences at a party in December 1844, where laughing gas (nitrous oxide) was used, Wells experimented with it as an anaesthetic during dental extractions, using himself as the first subject. By January 1845 he had employed the technique successfully in fifteen cases and made arrangements for its use as a general anaesthetic for a major operation at Massachusetts General Hospital. The experiment was a failure and he became discouraged from further enterprise in the field. He was eventually confined in an asylum, and very shortly after committed suicide.[br]Bibliography1838, An Essay on Teeth.1847, A History of the Discovery of the Application of Nitrous Oxide Gas, Ether and Other Vapours to Surgical Operations, Hartford.Further ReadingB.M.Duncum, 1947, Development of Inhalational Anaesthesia.MG
