Abstract: A device used to remove surface covering materials such as shingles. The device is comprised of an end handle having a plurality of switches and an anchoring mechanism, a handle shaft with a straight and curved portion, a secondary handle, and a base assembly. The anchoring mechanism can be used to secure the device to its work surface. The base assembly provides the mechanisms to automate the removal of shingles or other surface covering materials fastened using fasteners such as nails. The base assembly includes a blade assembly, a rotary support, a lever, a piston assembly, and a switch valve. The switch valve controls the routing of the fluid supply connected to the device. The device is powered by a supply of air or other fluid from a source such as a compressor.

Abstract: A material handling device to be used on non-horizontal platforms such as roofs, hills, construction sites, and other sloped surfaces. The device is comprised of a large blade for collecting debris or other materials such as shingles. The blade connects to a first handle that hangs forwardly over the opening of the blade. This handle is meant to assist lifting by placing the handle over the center of gravity of the load in the shovel. The blade is also attached to an angle adjustment pivot assembly. The pivot assembly is attached to an elongated handle. The adjustment mechanism adjusts the angle between the blade and the shaft. At the first end of the shaft is an anchor assembly, comprising an anchoring pin. The anchoring pin can be hammered into the surface to secure the shovel from falling or slipping. The shaft is then connected at its second end to a second anchor.

Abstract: A nailer carries a supply of coil nails, such as commonly used by roofers, and is swung by hand like a hammer. Each swing drives out a nail, and advances another nail ready to be driven.
