ABSTRACT:
A collar assembly is described, for use on a concrete cutter, which enables the major portion of the machine to be easily detached from a stuck sawblade and moved forwardly or rearwardly away from the blade so the blade can be cut out. The outer end of the shaft has a recess of the same diameter as the hole in the blade, and has a smaller threaded hole therein. The outer blade plate which lies on a face of the blade opposite the shaft, has a projecting collar that passes through the hole in the blade and into the recess in the face of the shaft, and a screw passing through the parts fastens them together.
