Abstract
403,487. Actuating controllers. ENGLISH ELECTRIC CO., Ltd., 28, Kingsway, London, SCARF, C. T., Woodcroft, Rednal, Worcestershire, and BERTLES, E. J., 1, Norbury Road, Eccleshill, Bradford, Yorkshire. Sept. 22, 1932, No. 26383. [Class 38 (iii).] An electric-motor starting-rheostat is operated by an auxiliary motor whose speed is dependent upon the position of the moving member of the rheostat. As shown, a continuously running pilot-motor 1 operates the shaft 4 of a liquid starting-rheostat through a clutch 2. Anticlockwise movement of an operating handle 7a brings a contact 6 into engagement with a contact sector 5 carried by the shaft 4, thereby energizing a coil 3 to close the clutch 2 until the starting resistance has decreased to a value determined by the position of handle 7a, the speed of the pilot-motor 1 being simultaneously reduced by a shunt regulator 8 operated from the shaft 4.
