Abstract

1,028,794. Brushes for dynamo electric machines. STACKPOLE CARBON CO. Oct. 11, 1963 [Nov. 29, 1962], No. 40220/63. Heading H2A. An electric brush B comprises two thin carbon brush half sections 7, 8 disposed faceto-face and substantially parallel, and a resilient member 11, 12 disposed between the parallel faces, in engagement with both and being connected to one of the faces. As shown, the brush halves 7, 8 are kept in close contact with the parallel sides of a brush holder 1 by the members 11, 12 which may be wire springs or rubber-like plugs glued in pockets 13 so that when the direction of rotation of the commutator 2 or a slip ring is reversed no movement or chatter occurs and therefore no reseating is necessary. The brush is urged into contact with the commutator 2 by a spring 4.
