  • Patent number: 5370433
    Abstract: This invention is a combination pickup device and tine cleaner having an elongated sleeve with an actuating shaft mounted therein. A tine head is mounted on one end of the sleeve and a handle on the other end. A plurality of tines outwardly project from the tine head on the opposite side from the sleeve. A cleaning plate, with openings in axial alignment with the tines, is mounted on the end of the actuating shaft adjacent the tine head. An actuating knob is mounted on the opposite end of the shaft so that as debris is picked up by the tines, the plate will be pushed up adjacent to the tine head causing the actuating knob to move out of the sleeve adjacent the handle. By pushing on the knob, the shaft can be forced back into the sleeve adjacent the handle which will cause the cleaning plate to move down the tines to clean the same. A height adjustable handle provided in a modification. Also, a pin to lock the device with the tips of the tines covered by the cleaning plate is provided.
