Abstract

894,912. Electric circuit-breakers. MURRAY MANUFACTURING CORPORATION. Dec. 15, 1958 [Jan. 2, 1958], No. 40373/58. Class 38 (5). Two single-pole bus-bars as disclosed in Specification 894,406 are interconnected by a transfer member 34 so that they are both tripped on a single pole fault. The transfer member is cross-shaped and connects the two trip members 20, thus allowing the roller assembly 17 to release the moving contact carrier 7.
