ABSTRACT:
The shingle removing machine includes a frame supporting a power source, which, in turn, drives a lateral axle with a wheel at each end thereof, with each wheel having an eccentric pin driving a blade drive arm. Separate wheels support the frame. Each blade drive arm extends forwardly and has a relatively wide shingle removal blade at its forward end. The blades extend substantially the width of the machine. The forward ends of the blade drive arms are interconnected and include rollers riding on sloped ramps on the forward end of the frame. Rotation of the blade arm drive wheels reciprocates the blade drive arms forwardly and rearwardly, with the blades also lifting and lowering during the cycle as the forward ends of the arms ride up and down the ramps. The blade drive arm assembly may be quickly and easily disassembled for maintenance and repair in the field.
