  • Patent number: 4673219
    Abstract: A motor powered, drum equipped, manually operable shingle removal tool for use by roofing contractors, home improvement companies and the like. A rigid, steel frame mechanically supports a conventional internal combustion engine linked through appropriate belts and pulleys to a front-mounted rotary drum. A plurality of rigid cutting teeth disposed about the outer surface of the cylindrical drum are adapted to forcibly contact the shingles to be removed. A lower sled which guides the tool along the roof surface may be selectively adjusted to facilitate proper elevation of the rotary drum above the shingle surface at a suitable height for optimum operation. The cutting teeth of the drum may be adjustably positioned relative to the outer surface of the drum to compensate for adjustment of the sled. A selectively adjustable elongated handle coupled to the rear of the machine frame directly above a pair of caster wheels facilitate maneuvering of the tool.
