Abstract:
In one embodiment of the present invention there is provided a brush holder for use with an electric motor, generator, or actuating device. The brush holder includes a body having an upper portion and a lower portion. A pair of flanges separately extends from opposing sides of the lower portion. Each flange includes a channel to provide a method of adjustably attaching the body to the device. A pair of members separately extends from opposing sides of the upper portion and each member includes a curved surface to accommodate coil ends of a constant force spring. A lateral bore is positioned through the body with openings to the bore being positioned about the pair of members. The bore is sized to accommodate a middle section of a constant force spring. An anterior bore positioned through the body transverses the lateral bore and sized to accommodate a carbon brush.
