ABSTRACT:
An apparatus for removing flat members from a surface uses a wedging pivotal blade. A mobile frame has a blade pivotally attached to its front end. The blade is movable between an upper and a lower position relative to the frame. The blade is positioned to be substantially in contact with the surface when it is in the lower position. An air cylinder will selectively lift the blade from the lower position to the upper position. As the frame is advanced, the blade is wedged between the flat members and the surface. The blade is raised from the lower position to the upper position, separating the flat members from the surface.
