Abstract: An apparatus for rapidly refilling a dry wall cement dispensing tool from a dry wall cement-filled bucket containing a thick-walled, heavy, metal pump tube for submerging into the dry wall cement contained therein, all of a weight to provide the pump tube with a low center of gravity when set in the bucket of dry wall cement, a cement-moving piston attached to the pump rod for reciprocal motion inside the pump tube, a thin-walled, light weight transfer device lighter in weight than the pump tube, extending outward from the aperture top end of the pump tube and in hydraulic communication therewith including a nozzle device for conveying the cement from the heavy pump tube into the cement dispensing tool, and a thin-walled, light weight pneumatic rectilinear reciprocating device lighter in weight than the pump tube, mounted above the tube of a size easily balanced by hand, interconnected the pump rod and including an actuation valve, for sequentially and rapidly raising and lowering the piston in the heavy pump

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
