ABSTRACT:
My invention is particularly adapted for metal saws having disc-like cutters, and especially abrasive disc saws, wherein the saw is fixed to a shaft which is rotatable within a bearing located at one end of a rocker arm. A drive motor, preferably an electric motor, is mounted on the other end of the arm and the latter is pivoted intermediate the saw and the motor on a bracket extending upwardly from a base. The arm swings about the pivot to move the saw toward and away from the work to be cut, which work is clamped within a vise secured to the upper surface of the base. The improvement herein disclosed comprises means for adjusting the amount the saw moves in directions toward and away from the work so that the saw does not "cut air"; that is so that the saw is halted in its up position just slightly above the work, and in its down position just slightly below the work. The saw is activated through a cycle wherein it moves down to engage and cut through the work and then automatically raise to, and remain in, its upper position, ready for the next cutting cycle after the work has been moved longitudinally and again clamped.
