ABSTRACT:
A brush holder apparatus and method for biasing a brush outwardly of a brush box. A brush box cover is slidingly disposed over an electrical cable along with a coil spring. Next, a brush shunt is electrically secured to an end portion of the electrical cable by a crimp member. The brush box cover is then slidably urged towards a brush secured at a terminal end of the brush shunt. This causes the brush shunt to be folded so as to place it in general longitudinal alignment and parallel with the electrical cable. The brush box cover is then further slid along the electrical cable, thus urging the spring over the brush shunt and into engagement with the brush electrically secured at the terminal (i.e., outer) end portion of the brush shunt. The brush box cover is further slid along the electrical cable until the crimp member and a portion of the brush shunt become wedgingly engaged in a portion of the brush box cover, to thereby hold the spring in a compressed condition between the brush box cover and the brush. Accordingly, there is no need to first compress the spring and hold the spring compressed while the brush shunt is attached to the electrical cable. The apparatus and method significantly eases the manner in which a brush holder may be assembled.
