Abstract
A brush assembly for engaging and conducting electricity to or from a surface is provided. The brush assembly comprises a monolithic, electrically conductive bus block and a bristle holder removably attached to the bus block. The bristle holder is formed as a monolithic block having a plurality of parallel bristle holes formed therethrough. The brush assembly further comprises a plurality of bristle assemblies, each bristle assembly having an elongate, electrically conductive bristle and an electrically conductive bristle cap having a sleeve, the proximal end of the bristle being secured within the sleeve so that the bristle is in electrical communication with the sleeve. At least a portion of the bristle cap of each bristle assembly is removably disposed within an associated bristle hole so that the bristle of each bristle assembly extends through its associated bristle hole and downwardly away from the lower bristle holder surface. Each bristle cap is in electrical communication with the bus block.
