7 Sprague, Frank Julian
[br]b. 25 July 1857 Milford, Connecticut, USAd. 25 October 1934 New York, USA[br]American electrical engineer and inventor, a leading innovator in electric propulsion systems for urban transport.[br]Graduating from the United States Naval Academy, Annapolis, in 1878, Sprague served at sea and with various shore establishments. In 1883 he resigned from the Navy and obtained employment with the Edison Company; but being convinced that the use of electricity for motive power was as important as that for illumination, in 1884 he founded the Sprague Electric Railway and Motor Company. Sprague began to develop reliable and efficient motors in large sizes, marketing 15 hp (11 kW) examples by 1885. He devised the method of collecting current by using a wooden, spring-loaded rod to press a roller against the underside of an overhead wire. The installation by Sprague in 1888 of a street tramway on a large scale in Richmond, Virginia, was to become the prototype of the universally adopted trolley system with overhead conductor and the beginning of commercial electric traction. Following the success of the Richmond tramway the company equipped sixty-seven other railways before its merger with Edison General Electric in 1890. The Sprague traction motor supported on the axle of electric streetcars and flexibly mounted to the bogie set a pattern that was widely adopted for many years.Encouraged by successful experiments with multiple-sheave electric elevators, the Sprague Elevator Company was formed and installed the first set of high-speed passenger cars in 1893–4. These effectively displaced hydraulic elevators in larger buildings. From experience with control systems for these, he developed his system of multiple-unit control for electric trains, which other engineers had considered impracticable. In Sprague's system, a master controller situated in the driver's cab operated electrically at a distance the contactors and reversers which controlled the motors distributed down the train. After years of experiment, Sprague's multiple-unit control was put into use for the first time in 1898 by the Chicago South Side Elevated Railway: within fifteen years multiple-unit operation was used worldwide.[br]Principal Honours and DistinctionsPresident, American Institute of Electrical Engineers 1892–3.

8 Weston, Edward
SUBJECT AREA: Electricity[br]b. 9 May 1850 Oswestry, Englandd. 20 August 1936 Montclair, New Jersey, USA[br]English (naturalized American) inventor noted for his contribution to the technology of electrical measurements.[br]Although he developed dynamos for electroplating and lighting, Weston's major contribution to technology was his invention of a moving-coil voltmeter and the standard cell which bears his name. After some years as a medical student, during which he gained a knowledge of chemistry, he abandoned his studies. Emigrating to New York in 1870, he was employed by a manufacturer of photographic chemicals. There followed a period with an electroplating company during which he built his first dynamo. In 1877 some business associates financed a company to build these machines and, later, arc-lighting equipment. By 1882 the Weston Company had been absorbed into the United States Electric Lighting Company, which had a counterpart in Britain, the Maxim Weston Company. By the time Weston resigned from the company, in 1886, he had been granted 186 patents. He then began the work in which he made his greatest contribution, the science of electrical measurement.The Weston meter, the first successful portable measuring instrument with a pivoted coil, was made in 1886. By careful arrangement of the magnet, coil and control springs, he achieved a design with a well-damped movement, which retained its calibration. These instruments were produced commercially on a large scale and the moving-coil principle was soon adopted by many manufacturers. In 1892 he invented manganin, an alloy with a small negative temperature coefficient, for use as resistances in his voltmeters.The Weston standard cell was invented in 1892. Using his chemical knowledge he produced a cell, based on mercury and cadmium, which replaced the Clark cell as a voltage reference source. The Weston cell became the recognized standard at the International Conference on Electrical Units and Standards held in London in 1908.[br]Principal Honours and DistinctionsPresident, AIEE 1888–9.
