摘要： 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.

摘要： 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.
摘要翻译： 我的发明特别适用于具有盘状切割器，特别是磨盘的金属锯，其中锯被固定到可在位于摇臂的一端的轴承内旋转的轴。 驱动马达，优选地是电动马达，安装在臂的另一端，而后者则在锯和电动机之间枢转在从底座向上延伸的托架上。 臂围绕枢轴摆动以使锯朝向和远离待切割的工件移动，该工件夹紧在固定到基座的上表面的虎钳内。 本文公开的改进包括用于调节锯在朝向和离开工件的方向上移动的量的装置，使得锯不“切割空气”; 那就是锯子在刚刚稍微高于工作的上方位置停下来，而在其稍低于工作的下方位置。 锯通过一个循环被启动，其中它向下移动以接合和切割工件，然后自动升高到并保持在其上部位置，准备好在工件被纵向移动并再次夹紧之后进行下一个切割循环。
