  • Patent number: 5540321
    Abstract: A means and method for moving objects (10) having a stand (12) and at least one support arm (14) movably connected to the stand (12). At least a pair of counter rotatable shafts (16 and 18) are connected with the support arm (14) and movable belts (20) for moving objects (64, 68) surrounds each counter rotatable shaft (16 and 18) so that an upper and lower surface (38 and 40) are formed by the belt (20) and each surface moves together in the same direction. The moveable belts (20) are movable by means of friction, or by a handle (22), or by some other suitable mechanical or electrical-mechanical means, in a direction that causes the device (10) to gently lift up and incrementally crawl under the object (64, 68) to be moved in one direction and to move out from under the object (64, 68) being deposited when moved in the other direction.
