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.

Abstract: A dust collecting system for belt sanders and the like which prevents dust and grit produced during the sanding of objects from entering the air which the operator breathes. The system serves as the closed base or stand for the belt sander, contains a powered air moving device, a baffle to trap larger particles of grit, a standard furnace filter to remove dust and smaller particles of grit, a control switch to start and stop the sander, a filter examination and removal plate and a cleanout plate.
