Abstract
879,469. Brushes for dynamo-electric machines. ENGLISH ELECTRIC CO. Ltd. Feb. 5, 1959 [Feb. 11, 1958], No. 4495/58. Class 35. Two thin brushes 2 in the same box 3 are separately loaded by spring-arms 4 passing over the top of both of them by providing cut-away portions 10 on each brush to clear the arm pressing on the other brush and allow for different rates of wear of the brushes. In the form shown, separate arms press on the upstanding portions of each brush, but in a modification, a single spring- arm with a forked end may be used. Current is shunted from the spring-arms by a flexible braid sweated to a plate 8 and riveted at its other end to the brush-holder frame 1. In a modification one brush may be cut away at its middle to receive two pressure-arms, and the other cut away at its sides to receive one.
