Abstract:
A powered reciprocating hand-held assembly for expanding the capabilities of power rotary tools with flex rotor shafts comprising a two-piece enclosure wherein a front one-piece enclosure serves to slidably enclose a reciprocating piece having a cylindrical shaft protrusion portion and a concave void protrusion portion, wherein an end of said cylindrical shaft protrusion portion receives a tool holder, wherein an end of said concave void protrusion portion having an integral cam follower, said front one-piece enclosure further serves to captivate a cylindrical single row radial bearing and serves to enclose a rotating piece and serves to mate with a rear one-piece enclosure; said cam follower connecting to said rotating piece, said cylindrical single row radial bearing being located juxtaposed to said concave void protrusion portion; wherein a rear one-piece enclosure encloses a means for converting rotary motion to reciprocal motion and serves to enclose a portion of the rotating end of a hand piece of a flex rotor shaft and serves to be firmly affixed to a flex rotor shaft and serves to be installed and removed from a flex rotor shaft and serves to mate with a front one-piece enclosure, a means for securing one of a plurality of reciprocative cutting tools to said assembly, and a means for securing said assembly to said flex rotor shaft of a power rotary tool wherein the previously unavailable expanded capabilities include reciprocative cutting, carving, sawing, chiseling, filing, sanding, and engraving of wood, wood-based products, metals, and plastics and engineering resins whereby a knowledgeable user can perform more detailed work on delicate work pieces than is possible from using a power rotary tool having only rotary cutting attachments.
