Abstract
The reciprocably supported member is accompanied by means whereby its stroke can be relocated so that it can be used to drive its support if desired, even while it is simultaneously driving a tool or the like connected therewith. Also, the member may have its own onboard drive means; as well as onboard means for removing any debris that the tool generates. The drive means may comprise a combustion engine and the debris removal means may use the combustion gases of the engine as a flush medium for the same. Ordinarily, the flush medium is discharged adjacent the outer periphery of the working face of the tool and removes the debris through apertures adjacent the outer peripheral edge of the same. Other features are also described.
