Abstract

1,134,498. Brush gear for dynamo-electric machines; collectors. INTERNATIONAL RESEARCH & DEVELOPMENT CO. Ltd. 2 Aug., 1966 [6 Aug., 1965], No. 33850/65. Headings H2A and H2E. An electrical current transfer device comprises an arcuate solid electrically conducting brush 1 having at one end a contact face 1a pressed into engagement with a conducting surface S by a biasing means exerting torque about the pivotal axis A of a support arm 2 to which the other end 1b of the brush is attached, and substantially uniform contact pressure is maintained by causing the brush cross-sectional area to decrease away from the axis. The invention is applicable to the commutator or slip ring of a dynamo-electric machine, specifically the homopolar machine disclosed in Specification 1,133,724, and in the embodiment shown the carbon or graphite brush has a trapezoidal cross-section and the means comprise a rod 4 biased by a spring 5 adjustable by a screwed sleeve 6.
