Abstract
1,158,259. Brushgear for electrical machines. H. A. L. VENNER (Elfin-Union A. G. fur Elektrische Industrie). 12 Dec., 1966, No. 55565/66. Heading H2A. In an electric machine brushgear including a pre-stressed spiral spring 7 having an uncoiled end region secured to a brushholder (4), Fig. 1 whilst the coiled part in tending to close up exerts a force on the end of a carbon brush 10 to press it against a commutator or slip ring (2), the spring is insulated and its coiled part is wound on a contact member 11 which is shaped as a body of revolution and engages the brush end to electrically connect same to a current conductors) 30. In the embodiment shown, the member 11 is a roller of silver or is silver coated having flanges 11<SP>1</SP>, 1111 engaging a brush trough 10<SP>1</SP> and whose insulation from the spring 7 is a sleeve 90. In other embodiments the members are pins insulated by coatings e.g. of paint or sintering, or by a hardboard plate riveted to the spring uncoiled end. The brush may be split, may have in its end a dovetail groove to facilitate removal by a clamp, and the gear is applicable to traction motors.
