  • Patent number: 7173359
    Abstract: A universal motor has a brush cage assembly in which a U-shaped clip 34 is located about a wall of a through hole 28 of a bearing bracket 24 for receiving a brush cage 30. The clip 34 has an outer limb 42 with inwardly and rearwardly directed barbs 44 to grip an outer surface of the wall to prevent removal of the clip 34 and an inner limb 36 with outwardly and forwardly directed barbs 42 which resiliently deform as the cage 30 is inserted to snare the cage 30 should it move in the opposite direction. The clip 34 thus prevents withdrawal of the brush cage 30 and provides a lateral spring force against the cage 30 to reduce cage lateral position tolerance and movement.
