Abstract

919,952. Brushes for dynamo-electric machines. WEISS, E., [trading as WEISS INHABER E. WEISS LAUFWERKFABRIK, PAUL]. Feb. 1, 1961 [Feb. 4, 1960; July 26, 1960], No. 3875/61. Class 35. In a commutator brush unit, brushes 5, 6 each comprising a strip of metallic gauze are welded or soldered at one or more places to leaf-springs 1, 2 which urge relatively large areas of the brushes 5, 6 against the commutator 11. The leaf-springs may be trough-shaped, as shown, at their free ends, the base of the trough having a portion 13 (Fig. 6) excised therefrom. Each brush may comprise more than one layer of gauze. Said layers may be produced by flat rolling the gauze prior to securing it to the leafspring (Figs. 8-13, not shown). The springs are attached to a plastic bracket 16 by extensions 18, 17 which pass through slots 19 and oblique slots 14, 15, respectively. The extension 18 may comprise the terminal member.
