Abstract
905,641. Automatic circuit-breakers. CRABTREE & CO. Ltd., J. A. May 25, 1960 [June 16, 1959], No. 43427/61. Divided out of 905,639. Drawings to Specification. Class 38 (5). A moulded case circuit-breaker has electromagnetically-operated tripping means including an armature floatably located on a rivet projecting from a magnet frame. The circuitbreaker is that described in Specification 905,639. Specifications 905,640 and 905,642 also are referred to.
