  • Taper sleeve driver for thrust bearing
    Patent number: 10227989
    Abstract: A thrust bearing assembly configured to reduce the axial displacement of a shaft includes a stationary thrust bearing, a thrust runner adjacent to the thrust bearing and a taper sleeve driver. The thrust runner includes a central passage. The taper sleeve driver includes an interior surface in contact with the shaft and an exterior surface in contact with the central passage of the thrust runner. The taper sleeve driver has a tapered exterior surface that applies a radially directed clamping force against the thrust runner as the taper sleeve driver is engaged within the central passage.

  • AUTOMATIC LIGHT SWITCH AND RELATED METHOD
    Publication number: 20090288937
    Abstract: An automatic switch control fits over a switch on a wall to move a toggle of the switch between an on position and an off position. The automatic switch control generally includes a housing and a wheel member rotatably supported by the housing. The wheel member has a cam member with a ramp surface. An electric motor is operable to rotate the wheel member about an axis of rotation that is generally perpendicular to the wall. A first plunger mechanism has a first spring member that is operable to urge a first cam follower into sliding engagement with the ramp surface. A second plunger mechanism has a second spring member that is operable to urge a second cam follower into sliding engagement with the ramp surface. The second plunger mechanism is disposed on an opposite side of the toggle from the first plunger mechanism when the automatic switch control is installed over the switch.
