ABSTRACT:
A shingle removal tool includes a support frame, a mechanism supported along the bottom of the support frame for moving the shingle removal tool along a surface, and a shingle removal plate having a topside, an underside and a shingle removing end. A rigid linkage has a first end and a second end, wherein the first end of the linkage is hingedly connected to the support frame, and the second end of the linkage is hingedly connected to the underside of the shingle removal plate. A flange depends from the underside of the shingle removing tool, the flange having a length. A rotator is supported by the support frame. A rotatable actuator is rotated by the rotator, and has an eccentric axis of rotation. The rotatable actuator is connected to the flange such that the flange moves about the axis of rotation while maintaining substantially the same orientation, movement of the flange resulting in corresponding movement of the shingle removal plate to which the flange is attached. The connection of the rotatable actuator to the flange being adjustable, thereby altering the shingle removal plate movement.
