Abstract
532,277. Master control of A.C. motors. M. & C. SWITCHGEAR, Ltd., and RICHARDSON, F. B. Aug. 24, 1939, No. 24335. (Class 38 (iii)] A motor K driving a coal cutter or conveyer is controlled at the motor or at a remote switch A by control over the normal pilot conductor 9. The main contactor F is controlled by a relay 10, which although held close by the normal current in the pilot 9 will not close unless one or other resistances 8, 13 is momentarily shorted. A switch 16 in the shunt around resistance 13 can be locked open and the key removed by the operator so as to prevent the motor being started from the remote switch A.
