Abstract: A device for picking up animal excrement or other refuse that includes a disposable replaceable collection box placed in a saddle box. The saddle box is attached to an elongated handle which includes an outer tubular member surrounding an inner shaft. The saddle cooperates with chambers molded outward on the exterior of the disposable box to control opening and closing of the disposable box. A button like switch protrudes through the outer tubular member of the handle and is attached to the inner shaft member. Downward force applied to the switch transmits the force through the inner shaft, and causes downward motion of a pusher plate attached to the end of the inner shaft. The pusher plate applies the force to the disposable box through a ridge on the top of the box, thereby causing outward deflection of the side walls of the saddle box and inducing the box to open to receive dung.

Abstract: A portable, battery operated sanding or surface treatment device well adapted for use on a backyard barbeque grill. A combination handle/battery compartment extends downward from the horizontal element of an L-shaped bracket. An electric motor which is contained inside a motor casing is provided. The motor casing includes a portion of larger diameter and a portion of smaller diameter. Extending from the end of the motor casing of larger diameter is a rotating drive shaft. Attached to the drive shaft is a cylinder drive of predetermined span. An annular bearing assembly is provided whose external diameter is substantially similar to the predetermined span of the cylinder drive and whose internal diameter is slightly larger than the dimension of the smaller portion of the motor casing. The bearing assembly surrounds the smaller portion of the motor casing and the motor casing is screwed to the vertical portion of the L-shaped bracket.
