Abstract: In an engine-powered wheeled vehicle, having a clutch interposed the engine and the drive wheel, actuated through a clutch cable operated by a moveable engaging/disengaging clutch handle, a clutch oscillator assembly including a chassis for mounting on the vehicle intermediate the clutch and the clutch handle, a shaft supported on the chasis for powered rotation about a fixed axis, a switched for interrupting the power to the shaft to cause controlled rotation thereof, a cyclic drive in association with the shaft for alternately pulling and releasing the clutch cable as a function of rotation of the shaft and including a work plate pivotally mounted on the chassis arranged to be driven by the shaft and further including a lever pivotally mounted on the chassis having one end in releasable contact with the clutch cable, wherein the cyclic drive includes a post mounted on the work plate, spaced-apart from the pivotal mounting thereof, and adapted to move as the work plate is turned, to create rhythmic contact b

Abstract: A novel hydraulic, fluid-filled shock absorber including a shock absorber chamber bounded by cylindrical walls and opposed, spaced-apart first and second end plates including first means for anchoring the chamber to a frame, a shock absorber shaft passing axially through the chamber and end plates including second means for connection to a separate oscillatory member, a work disc pivotally mounted transverse to the shaft inside the chamber intermediate the first and second end plates, a baffle fixedly mounted inside the chamber in fluid-sealing relationship therein having at least one aperture formed therethrough, a wiper baffle axially mounted to the shaft intermediate the disc and the first end plate extending outward into fluid-sealing relationship against the chamber walls to effectively divide the chamber into first and second subchambers so that rotation of the shaft forces fluid from one subchamber through the aperture into the other subchamber, a first pivot pin extending inward from the second end pl
