ABSTRACT:
An attachment for a staple gun tacker having a staple driving blade is disclosed which is adapted to be used in driving and setting a rivet of the type having a pin member mounted in a headed rivet shank having an expandable workpiece piercing free end. The attachment includes a housing adapted to be frictionally engaged on the working end of a staple gun tacker and having a bore located to be generally in axial alignment with the driving blade of the staple gun tacker. A hollow bushing is mounted in the housing bore and a pin punch is slidably mounted in the bushing for axial movement therein. A spring biases the pin punch towards the driving blade of the staple gun tacker with the bushing and pin being positioned such that the pin punch is impacted by the driving blade of the staple gun tacker when it is operated to apply a driving force thereto, which force is used to drive the pin member of the rivet to expand the free end of the rivet.
