  • Patent number: 4746829
    Abstract: An improved brush gear assembly for use in a miniature motor. The brush gear assembly is mounted within the interior of the end cap of the motor and basically consists of three parts: a terminal element or fitting, a brush leaf element, and a brush. The terminal element consists of a generally planar brass part, a major part of which is defined as an elongated rectangular portion. One end of the rectangular portion defines a bending end. Near the bending end are disposed three staggered projections arranged generally in line adjacent to a transverse bending line formed on the rectangular portion. The leaf spring is formed from a substantially elongated planar copper strip, which has one end terminating in a bending portion. The remainder of the strip constitutes a spring portion and terminates at its other end in a brush receiving portion, which is reinforced by bending the sides in an upward direction.
