2 Sperry, Elmer Ambrose
[br]b. 21 October 1860 Cincinnatus, Cortland County, New York, USAd. 16 June 1930 Brooklyn, New York, USA[br]American entrepreneur who invented the gyrocompass.[br]Sperry was born into a farming community in Cortland County. He received a rudimentary education at the local school, but an interest in mechanical devices was aroused by the agricultural machinery he saw around him. His attendance at the Normal School in Cortland provided a useful theoretical background to his practical knowledge. He emerged in 1880 with an urge to pursue invention in electrical engineering, then a new and growing branch of technology. Within two years he was able to patent and demonstrate his arc lighting system, complete with its own generator, incorporating new methods of regulating its output. The Sperry Electric Light, Motor and Car Brake Company was set up to make and market the system, but it was difficult to keep pace with electric-lighting developments such as the incandescent lamp and alternating current, and the company ceased in 1887 and was replaced by the Sperry Electric Company, which itself was taken over by the General Electric Company.In the 1890s Sperry made useful inventions in electric mining machinery and then in electric street-or tramcars, with his patent electric brake and control system. The patents for the brake were important enough to be bought by General Electric. From 1894 to 1900 he was manufacturing electric motor cars of his own design, and in 1900 he set up a laboratory in Washington, where he pursued various electrochemical processes.In 1896 he began to work on the practical application of the principle of the gyroscope, where Sperry achieved his most notable inventions, the first of which was the gyrostabilizer for ships. The relatively narrow-hulled steamship rolled badly in heavy seas and in 1904 Ernst Otto Schuck, a German naval engineer, and Louis Brennan in England began experiments to correct this; their work stimulated Sperry to develop his own device. In 1908 he patented the active gyrostabilizer, which acted to correct a ship's roll as soon as it started. Three years later the US Navy agreed to try it on a destroyer, the USS Worden. The successful trials of the following year led to widespread adoption. Meanwhile, in 1910, Sperry set up the Sperry Gyroscope Company to extend the application to commercial shipping.At the same time, Sperry was working to apply the gyroscope principle to the ship's compass. The magnetic compass had worked well in wooden ships, but iron hulls and electrical machinery confused it. The great powers' race to build up their navies instigated an urgent search for a solution. In Germany, Anschütz-Kämpfe (1872–1931) in 1903 tested a form of gyrocompass and was encouraged by the authorities to demonstrate the device on the German flagship, the Deutschland. Its success led Sperry to develop his own version: fortunately for him, the US Navy preferred a home-grown product to a German one and gave Sperry all the backing he needed. A successful trial on a destroyer led to widespread acceptance in the US Navy, and Sperry was soon receiving orders from the British Admiralty and the Russian Navy.In the rapidly developing field of aeronautics, automatic stabilization was becoming an urgent need. In 1912 Sperry began work on a gyrostabilizer for aircraft. Two years later he was able to stage a spectacular demonstration of such a device at an air show near Paris.Sperry continued research, development and promotion in military and aviation technology almost to the last. In 1926 he sold the Sperry Gyroscope Company to enable him to devote more time to invention.[br]Principal Honours and DistinctionsJohn Fritz Medal 1927. President, American Society of Mechanical Engineers 1928.BibliographySperry filed over 400 patents, of which two can be singled out: 1908. US patent no. 434,048 (ship gyroscope); 1909. US patent no. 519,533 (ship gyrocompass set).Further ReadingT.P.Hughes, 1971, Elmer Sperry, Inventor and Engineer, Baltimore: Johns Hopkins University Press (a full and well-documented biography, with lists of his patents and published writings).LRD -

4 Kind, Karl Gotthelf
SUBJECT AREA: Mining and extraction technology[br]b. 6 June 1801 Linda, near Freiberg, Germanyd. 9 March 1873 Saarbrücken, Germany[br]German engineer, pioneer in deep drilling.[br]The son of an ore miner in Saxony, Kind was engaged in his father's profession for some years before he joined Glenck's drillings for salt at Stotternheim, Thuringia. There in 1835, after trying for five years, he self-reliantly put down a 340 m (1,100 ft) deep well; his success lay in his use of fish joints of a similar construction to those used shortly before by von Oeynhausen in Westphalia. In order to improve their operational possibilities in aquiferous wells, in 1842 he developed his own free-fall device between the rod and the drill, which enabled the chisel to reach the bottom of the hole without hindrance. His invention was patented in France. Four years later, at Mondorf, Luxembourg, he put down a 736 m (2,415 ft) deep borehole, the deepest in the world at that time.Kind contributed further considerable improvements to deep drilling and was the first successfully to replace iron rods with wooden ones, on account of their buoyancy in water. The main reasons for his international reputation were his attempts to bore out shafts, which he carried out for the first time in the region of Forbach, France, in 1848. Three years later he was engaged in the Ruhr area by a Belgian-and English-financed mining company, later the Dahlbusch mining company in Gelsenkirchen, to drill a hole that was later enlarged to 4.4 m (14 1/2 ft) and made watertight by lining. Although he had already taken out a patent for boring and lining shafts in 1849 in Belgium, his wooden support did not qualify. It was the Belgian engineer Joseph Chaudron, in charge of the mining company, who overcame the difficulty of making the bottom of the borehole watertight. In 1854 they jointly founded a shaft-sinking company in Brussels which specialized in aquiferous formations and operated internationally.[br]Principal Honours and DistinctionsChevalier de la Légion d'honneur 1849.Bibliography1842, Anleitung zum Abteufen von Bohrlöchern, Luxembourg.Further ReadingH.G.Conrad, "Carl Gotthelf Kind", Neue deutsche Biographie 10:613–14.D.Hoffmann, 1959, 150 Jahre Tiefbohrungen in Deutschland, Vienna and Hamburg, pp. 20–5 (assesses his technological achievements).T.Tecklenburg, 1914, Handbuch der Tiefbohrkunde, 2nd end, Vol. VI, Berlin, pp. 36–9 (provides a detailed description of his equipment).J.Chaudron, 1862, "Über die nach dem Kindschen Erdbohrverfahren in Belgien ausgeführten Schachtbohrarbeiten", Berg-und Hüttenmännische Zeitung 21:402–4, (describes his contribution to making Kind's shafts watertight).WK -
5 Sauerbrun, Charles de, Baron von Drais
SUBJECT AREA: Land transport[br]b. 1785d. 1851[br]German popularizer of the first form of manumotive vehicle, the hobby-horse.[br]An engineer and agriculturalist who had to travel long distances over rough country, he evolved an improved design of velocipede. The original device appears to have been first shown in the gardens of the Palais Royal by the comte de Sivrac in 1791, a small wooden "horse" fitted with two wheels and propelled by the rider's legs thrusting alternately against the ground. It was not possible to turn the front wheel to steer the machine, a small variation from the straight being obtained by the rider leaning sideways. It is not known if de Sivrac was the inventor of the machine: it is likely that it had been in existence, probably as a child's toy, for a number of years. Its original name was the celerifière, but it was renamed the velocifère in 1793. The Baron's Draisienne was an improvement on this primitive machine; it had a triangulated wooden frame, an upholstered seat, a rear luggage seat and an armrest which took the thrust of the rider as he or she pushed against the ground. Furthermore, it was steerable. In some models there was a cordoperated brake and a prop stand, and the seat height could be adjusted. At least one machine was fitted with a milometer. Drais began limited manufacture and launched a long marketing and patenting campaign, part of which involved sending advertising letters to leading figures, including a number of kings.The Draisienne was first shown in public in April 1817: a ladies' version became available in 1819. Von Drais took out a patent in Baden on 12 January 1818 and followed with a French patent on 17 February. Three-and four-wheeled versions became available so the two men could take the ladies for a jaunt.Drais left his agricultural and forestry work and devoted his full time to the "Running Machine" business. Soon copies were being made and sold in Italy, Germany and Austria. In London, a Denis Johnson took out a patent in December 1818 for a "pedestrian curricle" which was soon nicknamed the dandy horse.[br]Further ReadingC.A.Caunter, 1955, Cycles: History and Development, London: Science Museum and HMSO.IMcNBiographical history of technology > Sauerbrun, Charles de, Baron von Drais

9 Davidson, Robert
[br]b. 18 April 1804 Aberdeen, Scotlandd. 16 November 1894 Aberdeen, Scotland[br]Scottish chemist, pioneer of electric power and builder of the first electric railway locomotives.[br]Davidson, son of an Aberdeen merchant, attended Marischal College, Aberdeen, between 1819 and 1822: his studies included mathematics, mechanics and chemistry. He subsequently joined his father's grocery business, which from time to time received enquiries for yeast: to meet these, Davidson began to manufacture yeast for sale and from that start built up a successful chemical manufacturing business with the emphasis on yeast and dyes. About 1837 he started to experiment first with electric batteries and then with motors. He invented a form of electromagnetic engine in which soft iron bars arranged on the periphery of a wooden cylinder, parallel to its axis, around which the cylinder could rotate, were attracted by fixed electromagnets. These were energized in turn by current controlled by a simple commutaring device. Electric current was produced by his batteries. His activities were brought to the attention of Michael Faraday and to the scientific world in general by a letter from Professor Forbes of King's College, Aberdeen. Davidson declined to patent his inventions, believing that all should be able freely to draw advantage from them, and in order to afford an opportunity for all interested parties to inspect them an exhibition was held at 36 Union Street, Aberdeen, in October 1840 to demonstrate his "apparatus actuated by electro-magnetic power". It included: a model locomotive carriage, large enough to carry two people, that ran on a railway; a turning lathe with tools for visitors to use; and a small printing machine. In the spring of 1842 he put on a similar exhibition in Edinburgh, this time including a sawmill. Davidson sought support from railway companies for further experiments and the construction of an electromagnetic locomotive; the Edinburgh exhibition successfully attracted the attention of the proprietors of the Edinburgh 585\& Glasgow Railway (E \& GR), whose line had been opened in February 1842. Davidson built a full-size locomotive incorporating his principle, apparently at the expense of the railway company. The locomotive weighed 7 tons: each of its two axles carried a cylinder upon which were fastened three iron bars, and four electromagnets were arranged in pairs on each side of the cylinders. The motors he used were reluctance motors, the power source being zinc-iron batteries. It was named Galvani and was demonstrated on the E \& GR that autumn, when it achieved a speed of 4 mph (6.4 km/h) while hauling a load of 6 tons over a distance of 1 1/2 miles (2.4 km); it was the first electric locomotive. Nevertheless, further support from the railway company was not forthcoming, although to some railway workers the locomotive seems to have appeared promising enough: they destroyed it in Luddite reaction. Davidson staged a further exhibition in London in 1843 without result and then, the cost of battery chemicals being high, ceased further experiments of this type. He survived long enough to see the electric railway become truly practicable in the 1880s.[br]Bibliography1840, letter, Mechanics Magazine, 33:53–5 (comparing his machine with that of William Hannis Taylor (2 November 1839, British patent no. 8,255)).Further Reading1891, Electrical World, 17:454.J.H.R.Body, 1935, "A note on electro-magnetic engines", Transactions of the Newcomen Society 14:104 (describes Davidson's locomotive).F.J.G.Haut, 1956, "The early history of the electric locomotive", Transactions of the Newcomen Society 27 (describes Davidson's locomotive).A.F.Anderson, 1974, "Unusual electric machines", Electronics \& Power 14 (November) (biographical information).—1975, "Robert Davidson.

10 Hooke, Robert
[br]b. 18 July 1635 Freshwater, Isle of Wight, Englandd. 3 March 1703 London, England[br]English physicist, astronomer and mechanician.[br]Son of Revd John Hooke, minister of the parish, he was a sickly child who was subject to headaches which prevented protracted study. He devoted his time while alone to making mechanical models including a wooden clock. On the death of his father in October 1648 he was left £100 and went to London, where he became a pupil of Sir Peter Lely and then went to Westminster School under Dr Busby. There he learned the classical languages, some Hebrew and oriental languages while mastering six books of Euclid in one week. In 1653 he entered Christ Church College, Oxford, where he graduated MA in 1663, after studying chemistry and astronomy. In 1662 he was appointed Curator of Experiments to the Royal Society and was elected a Fellow in 1663. In 1665 his appointment was made permanent and he was given apartments in Gresham College, where he lived until his death in 1703. He was an indefatigable experimenter, perhaps best known for the invention of the universal joint named after him. The properties of the atmosphere greatly engaged him and he devised many forms of the barometer. He was the first to apply the spiral spring to the regulation of the balance wheel of the watch in an attempt to measure longitude at sea, but he did not publish his results until after Huygens's reinvention of the device in 1675. Several of his "new watches" were made by Thomas Tompion, one of which was presented to King Charles II. He is said to have invented, among other devices, thirty different ways of flying, the first practical system of telegraphy, an odometer, a hearing aid, an arithmetical machine and a marine barometer. Hooke was a small man, somewhat deformed, with long, lank hair, who went about stooped and moved very quickly. He was of a melancholy and mistrustful disposition, ill-tempered and sharp-tongued. He slept little, often working all night and taking a nap during the day. John Aubrey, his near-contemporary, wrote of Hooke, "He is certainly the greatest Mechanick this day in the World." He is said to have been the first to establish the true principle of the arch. His eyesight failed and he was blind for the last year of his life. He is best known for his Micrographia, or some Physiological Descriptions of Minute Bodies, first published in 1665. After the Great Fire of London, he exhibited a model for the rebuilding of the City. This was not accepted, but it did result in Hooke's appointment as one of two City Surveyors. This proved a lucrative post and through it Hooke amassed a fortune of some thousands of pounds, which was found intact after his death some thirty years later. It had never been opened in the interim period. Among the buildings he designed were the new Bethlehem (Bedlam) Hospital, the College of Physicians and Montague House.[br]Principal Honours and DistinctionsFRS 1663; Secretary 1677–82.IMcN
