Abstract: Apparatus for removing an outer layer, or covering, such as of shingles from a flat surface such as a roof includes a frame with an elongated, linear cutting blade attached to a lower, forward portion thereof and adapted for displacement along and in contact with the roof. The apparatus further includes a blade drive arrangement for displacing the blade in a reciprocating manner along its length and parallel to the roof. Also attached to a forward portion of the frame immediately above the blade is a concave, upward extending deflector for directing the removed shingles forward of the apparatus as it is displaced over the roof. A handle extends from the frame to facilitate manual displacement of the apparatus over the roof as the roofing nails, or other attachment means, are served by the blade in removing the shingles from the roof.

Abstract: A prying blade (42) having an essentially triangular forward portion (43) is secured to a pipe handle (41) at an angle (D) of between about 20.degree.-25.degree.. The triangular forward portion is formed with a rounded or blunt apex region (47) and the two lateral sides (45a, 45b) have notches (44) therein, leaving teeth therebetween. The notches can engage nails for prying up roofing nails together with roofing shingles. The rear portion of the blade (49) is secured to the handle at a point rearwardly of the apex region, for example by welding, to form with the handle a triangular structure. The prying regions of the blades are thus securely supported. The triangular arrangement permits placement of the apex region of the prying bar between nails and removal by the notches in the sides (45a, 45b), or direct prying by the prying bar of a nail caught at the apex region.

Abstract: The apparatus has a housing which slidably mounts a blade assembly for reciprocation thereof, fore and aft, perpendicular to the longitudinal axis of the housing, for the purpose of cutting shingle nails. The blade assembly slides upon a plate, which terminates in a series of juxtapositioned teeth, which lifts shingles to give the blade assembly access to the nails. A prime mover, an electric motor in the disclosed embodiment, drives the blade assembly in reciprocation through a gear train and cranks confined within the housing. Vibration-induced, free-flow lubrication for the blade assembly is provided by a lubricant reservoir and manifold mounted upon the housing.

Abstract: Apparatus for removing roof shingles includes an elongated body having a handle at the upper end and a pivotally connected lift plate at the lower end. A piston and cylinder actuator mounted on the body and activated by a trigger mounted on the handle. A lift plate is pivotally mounted on the lower end of the body. A toggle linkage connects the actuator to the lift plate for pivoting the forward edge of the plate about a heel structure under the lift plate.

Abstract: A roofing materials removal device provides a guide system which secures the device and the operator in position on an inclined roof so that the roof can be traversed at various positions along different travel paths while supported. The removal device comprises a light-weight, durable, wheel supported frame, dual handles for leverage, an electric motor positioned low on the frame to give the device balance and stability. An angled blade reciprocating and riding on linear bearings is connected to spring-mounted tension bars. As the springs force the rear end of the tension bar upward, the forward end of the tension bars pivot downward causing the serrated, leading edge of the blade to slide between the roof covering material and the roof deck. The blade follows the contour of the roof deck dislodging roofing material including nails, roofing felt and shingles. The guide system is positioned on the opposite side of the roof ridge from the removal device.

Abstract: The invention is directed to a covering remover, the covering including roofing shingles. Removal of roofing shingles and other coverings presently requires hand tools, such as crow bars, hammers, shovels and nail pullers. This manual method is time and labor-intensive, as roofing needs to be removed in small individual sections. The present invention comprises a cylinder assembly with a rotatable shaft within the cylinder. Strapping is attached to and extends from the cylinder. A lifting force underneath the covering to be removed is accomplished when the cylinder assembly is rotated about its axis. This rotating assembly lifts whole sections of roofing and when removed from the cylinder, leaves the rolled-up section in a bale for convenient disposal.
