ABSTRACT:
For use with an electrical machine, a contact brush is provided which comprises a solid "carbon" block having a thin layer of electrically conductive, preferably carbon, fibers on a surface which contains the entering edge, or a surface which contains the leaving edge, or both such surfaces. The fibers have free ends contacting the relatively-moving counterface, e.g. a slip ring or commutator, close to the entering or leaving edge, thereby to provide near the respective edge a large number of contact points to obtain sparkless operation.
