Abstract: A motor assembly (10) includes a permanent magnet DC motor (16) having a shaft (24) mounted for rotation with a face gear pinion (26) associated with the shaft. A jack shaft and clutch assembly (18) is associated with the face gear pinion and is constructed and arranged to prevent back drive of the motor under certain operating conditions. A spur or helical pinion (40) is operatively associated with the jack shaft and clutch assembly. A drive member (56) is operatively associated with the spur or helical pinion such that movement of the shaft and face gear pinion moves the spur or helical pinion to drive the drive member. A housing structure is defined by an upper housing (14) joined with a lower housing (12). The motor, the face gear pinion, the jack shaft and clutch assembly, the spur or helical pinion and the drive member are housed within the housing structure. Only one of the upper or lower housings includes mounting structure (25) constructed and arranged to mount the motor assembly to another object.

Abstract: A brush card assembly 10 includes a brush card member 12, conductive contacts 14 provided on the brush card member, and brushes 16 mounted to be electrically in contact with the conductive contacts. The assembly 10 also includes brush box 18 associated with each of the brushes. Each brush box includes an integral spring 24 constructed and arranged to bias an associated brush to contact a commutator, and an integral retainer 26 constructed and arranged to exert pressure on the associated brush once the brush is disengaged from the commutator.
