Abstract
528,926. Electric motor controllers. VAUGHAN CRANE CO., Ltd., WOOD, F., and SADLER, G., V. May 17, 1939, No. 14694. [Class 38 (iii)] In speed-control gear for an A.C. commutator motor A, an induction regulator R is moved by a pilot motor B and a drum controller D controlling both the main motor and the pilot motor is connected to a limit switch E to prevent overrunning. Specification 409,485 is referred to.
