ABSTRACT:
A support has portions which define a working plane and an arm is pivotally mounted on this support at one end, and carries a circular saw blade which can be moved toward and away from the working plane as the arm is pivoted. Cooperating mechanical elements are provided on the arm and on the support and are power-driven so as to pivot the arm with the blade towards and away from the working plane. These mechanical elements may be rack and pinion constructions or they may be screw spindle and spindle-nut constructions.
