Abstract
A current transfer brush with a multiplicity of fibers of graphite which are combined to form a slider member and extend at least approximately perpendicular to the contact surface of the brush, having parts of electrically conductive material, in which the fibers comprise graphite fiber bundles, each of which is twisted with filaments of electrically conductive material giving the advantages of ease of twisting and permitting the ratio of metal to graphite in the brush to be predetermined.
Claims16
A current transfer brush comprising a slider member comprised of a plurality of graphite fiber bundles extending at least approximately perpendicular to the contact surface of the brush, each of said plurality of fiber bundles containing individual filaments of electrically conductive material twisted with said graphite fiber bundles and extending up to said contact surface of said brush, and a frame element retaining only the ends of said bundles facing away from the contact surface of said brush.
