  • Patent number: 7216845
    Abstract: A highly efficient apparatus for actuating a valve. An input mechanism drives the apparatus through an input member. Torque is increased as a plurality of driver discs eccentrically rotate about a central shaft member and engage an output member via low-friction, roller means. The output member engages a valve stem which opens or closes the valve.

  • Patent number: 7192011
    Abstract: The present invention is directed toward an apparatus for quickly configuring a jack to raise a load from its rest position. In particular, the present invention provides a jacking mechanism that telescopes from a locked, elevated position to a locked, lowered position in order to situate the jacking mechanism for raising a load. Correspondingly, the present invention provides a jacking mechanism that telescopes from its locked, lowered position to its locked, elevated position for stowing the mechanism between uses.

  • Patent number: 7192375
    Abstract: A device for increasing torque about a central member as a series of driver discs eccentrically rotate about a central shaft input member and alternatingly engage an output component via a low-friction, rolling engagement mechanism. Each disc is engaged with the other through a series of rings and dowels partially embedded within each disc. As the central input shaft rotates, each disc alternatingly engages the output component so the output, and central member, rotate with increased torque, albeit at a reduced speed.

  • Patent number: 7159939
    Abstract: An auxiliary seating unit is designed for a vehicle with a bed, such as a bed-type all terrain vehicle or pickup truck. The seating unit is designed with seats mounted to a support frame, the support frame having portions which rest squarely atop the vehicle's bed surface, white upper portions of the frame juxtapose and reversibly attach (using pins and cotter keys, nuts and bolts, or other reversible attachment means) to the upper margins of the vehicle's bed fence. Seats are securely attached to and supported by seat supports which extend from the portions of the support frame which attach to the vehicle.
