ABSTRACT:
A tool for applying fasteners to a workpiece includes a housing and a punch reciprocally mounted in the housing. The punch includes an elongated slot through which a feed plate that is slideably mounted within the housing passes. A cam stop member is rotatably and slideably mounted in the housing and biased to engage the punch. The punch includes a first surface to rotate the cam such that a punch engaging edge is positioned against the punch. A second surface is defined on the punch at a predetermined distance spaced from the first surface and is engaged by the edge of the cam at an incomplete stroke of the punch. A third surface on the punch is spaced a predetermined distance from the second surface. The third surface rotates the punch engaging surface of the cam away from the punch at the completion of a full stroke allowing return of the punch to its normal position.
