Abstract

1,116,458. Brushes for dynamo-electric machines. UNION CARBIDE CORPORATION. 6 June, 1966 [11 June, 1965], No. 25063/66. Heading H2A. The pad 22 on which the spring-arm presses is of insulating material, is secured by moulding or pressing into a groove 12 in the side of the brush, and has a coefficient of thermal expansion greater than that of the brush. The pressurepad may cover the two parts of a split brush (Fig. 3, not shown). The groove may be dovetailed (Fig. 2, not shown). The pad is of plastic, e.g. a compound of nylon and fibre glass, and it may be indexed in the slot by a dimple near the bottom of the groove.
