Abstract: A main body containing an electric motor reciprocally driving a rigid longitudinal extension which is frictionally suspended within a graspable sleeve may be held to guide a selected abrasive tool head coupled to the front end of the extension. Power may be supplied by a battery, rechargeable or replaceable, or by alternating current through a cord. A vacuum connected to a sanding head having a porous pad backed by an airtight manifold and attachable to the main body may run on alternating current or a battery. The sleeve may be connected to the main body to provide a continuous uninterrupted exterior. The speed may be varied with use of a variable resistor. An appropriate length stroke is obtained with a sufficiently large diameter driven disc pivotally connected to the extension with a rigid link arm. The tool may be used for powered sanding, scraping, or scrubbing with a wire brush, a bristle brush or an absorbent pad.

Abstract: About a rigid longitudinal extension a sleeve is frictionally suspended such that the extension may reciprocate freely within the sleeve while remaining relatively stationary longitudinally. The rear end of the extension is attachable to a reciprocating portable power tool and the forward end is attached to a tool head. In operation, the extension and the tool head reciprocate while the sleeve, grasped in one hand, is frictionally isolated from the reciprocation and consequently insulated from the vibration associated with the operation of a portable reciprocating portable power tool. A coupling upon the forward end of the extension facilitates the attachment of a variety of different tool ends. Frictional suspension of the sleeve about the extension by using a pair of springs or by using bearings between the sleeve and the extension is suggested.
