Abstract
415,413. Automatic circuit breakers. CRABTREE, J. A., Endwood, Little Aston Park, Sutton Coldfield. Feb. 21, 1933, No. 5682/34. Divided on 415,387 and addition to 415,129. [Class 38 (v).] The circuit-breaker described in the parent Specification is fitted with a trip catch a adapted, as by means of a cam surface a<5>, to definitely displace the arm b<1> of the bell-crank b to accelerate the opening movement of the contact, on heavy overload or in other circumstances where the spring-action may be inadequate.
