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. A flat platform tool head, primarily for sanding, brush heads and blade heads are also specifically suggested, as is coupling by use of threading and by use of hook and catch.
