Abstract

774,616. Brush-holders for dynamo-electric machines. FRANCK, A. April 18, 1955 [June 10, 1954; March 24, 1955], No. 11089/55. Class 35. A brush-holder comprises spaced brush supporting members radially projecting from a casing of a dynamo-electric machine, the said members being arranged so that a large area of the brush is exposed. In one embodiment, Fig. 1, the brush-holder comprises three strips 3c, 3f, 3g arranged to receive a brush having a hexagonal cross-section. The strips may be further arranged to hold a brush with a pentagonal or square section, but in the latter case there are either two angled strips 3a, 3b and one flat strip 3m as in Fig. 6, or only two angled strips as in Fig. 4 (not shown).
