Abstract:
1. An adapter for joining a pulling head to a fastener installation tool, wherein the tool includes an outer portion for applying compressive force and a puller shaft slidable axially and reciprocally within the outer portion for applying tensile force, and the pulling head includes an outer portion for applying compressive force to a workpiece and a draw bolt for applying tensile force to a fastener, with the draw bolt slidable axially and reciprocally over a stroke length within the outer portion; said adapter comprising: a sleeve assembly having a proximal portion mateable with the outer portion of the fastener installation tool and a distal portion threadedly engageable with the outer portion of the pulling head; and a puller shaft assembly having a proximal portion mateable with the puller shaft of the fastener installation tool and a distal portion threadedly engageable with the draw bolt of the pulling head; wherein: said sleeve assembly and said puller shaft assembly share an axis; said puller shaft assembly is slidable reciprocally along said axis within and relative to said sleeve assembly; said distal portion of said sleeve assembly is rotatable relative to said proximal portion of said sleeve assembly about said axis; said distal portion of said puller shaft assembly is rotatable relative to said proximal portion of said puller shaft about said axis; and said distal portions of said sleeve assembly and said puller shaft assembly are operative to allow simultaneous rotation about said axis repeatedly without changing the stroke length of the joined combination of the tool, said adapter, and the pulling head.
