81 Jablochkoff, Paul
[br]b. 14 September 1847 Serdobsk, Russiad. April 1894 St Petersburg, Russia[br]Russian military engineer and inventor of an electric "candle", the invention of which gave an immense impetus to electric lighting in the 1870s.[br]Jablochkoff studied at the Military Engineering College in St Petersburg. Having a scientific bent, he was sent to the Military Galvano Technical School. At the end of his military service in 1871 he was appointed Director General of the Moscow-Kursk telegraph lines for the Midi Railway Company. At this time he began to develop an interest in electric lighting, and in 1875 he left the Imperial Telegraph Service to devote his time exclusively to scientific pursuits. He found employment at the workshop of M Bréguet in Paris, where Gramme dynamos and Serrin arc lamps were being constructed. After some experimentation he found a means of producing a carbon arc that regulated itself without any mechanism. This lamp, the Jablochkoff candle, with two carbon rods placed parallel to each other and so close that an arc formed at the ends, could continue to burn until the rods were consumed. Plaster of Paris was used to separate the two electrodes and crumbled away as the carbon burned, thus exposing fresh carbon. These lamps were used in May 1878 in Paris to illuminate the avenue de l'Opéra, and later in Rome and London, and in essence were the first practical electric street lighting. Since there was no regulating mechanism, several candles could be placed in a single circuit. Despite inherent defects, such as the inability to restart the lamps after they were extinguished by wind or interruption of supply, they remained in use for some purposes for several years on account of their simplicity and cheapness. In 1877 Jablochkoff obtained the earliest patent to employ transformers to distribute current in an alternating-current circuit.[br]Bibliography11 September 1876, British patent no. 3,552 (Jablochkoff's candle).22 May 1877, British patent no. 1,996 (transformer or induction coil distribution).Further ReadingW.J.King, 1962, The Development of Electrical Technology in the 19th Century, Washington, DC: Smithsonian Institution, Paper 30, pp. 393–407 (a detailed account).

85 Holmes, Frederic Hale
[br]fl. 1850s–60s[br]British engineer who pioneered the electrical illumination of lighthouses in Great Britain.[br]An important application of the magneto generator was demonstrated by Holmes in 1853 when he showed that it might be used to supply an arc lamp. This had many implications for the future because it presented the possibility of making electric lighting economically successful. In 1856 he patented a machine with six disc armatures on a common axis rotating between seven banks of permanent magnets. The following year Holmes suggested the possible application of his invention to lighthouse illumination and a trial was arranged and observed by Faraday, who was at that time scientific adviser to Trinity House, the corporation entrusted with the care of light-houses in England and Wales. Although the trial was successful and gained the approval of Faraday, the Elder Brethren of Trinity House imposed strict conditions on Holmes's design for machines to be used for a more extensive trial. These included connecting the machine directly to a slow-speed steam engine, but this resulted in a reduced performance. The experiments of Holmes and Faraday were brought to the attention of the French lighthouse authorities and magneto generators manufactured by Société Alliance began to be installed in some lighthouses along the coast of France. After noticing the French commutatorless machines, Holmes produced an alternator of similar type in 1867. Two of these were constructed for a new lighthouse at Souter Point near Newcastle and two were installed in each of the two lighthouses at South Foreland. One of the machines from South Foreland that was in service from 1872 to 1922 is preserved in the Royal Museum of Scotland, Edinburgh. A Holmes generator is also preserved in the Science Museum, London. Holmes obtained a series of patents for generators between 1856 and 1869, with all but the last being of the magneto-electric type.[br]Bibliography7 March 1856, British patent no. 573 (the original patent for Holmes's invention).1863, "On magneto electricity and its application to lighthouse purposes", Journal of the Society of Arts 12:39–43.Further ReadingW.J.King, 1962, in The Development of Electrical Technology in the 19th Century; Washington, DC: Smithsonian Institution, Paper 30, pp. 351–63 (provides a detailed account of Holmes's generators).J.N.Douglas, 1879, "The electric light applied to lighthouse illumination", Proceedings of the Institution of Civil Engineers 57(3):77–110 (describes trials of Holmes's machines).GW -
86 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 -
