Patent ID: 8152038

Claim:
In a fastener-driving tool equipped with a fastener magazine, having a power source including a reciprocating driver blade for driving fasteners obtained from said magazine into a workpiece, and a reciprocating valve sleeve actuated by a cage, a nosepiece comprising: a nosepiece body configured for attachment at one end to said fastener tool and defining a fastener channel constructed and arranged for receiving said driver blade and said fasteners sequentially fed by said magazine, said fastener channel having a fastener outlet; a tubular pin guide disposed for reciprocal movement in said fastener channel and defining an internal passage for receiving fasteners traveling toward said outlet; a unitary actuator having an outer surface, an inner surface, a first end engaging said pin guide for common reciprocation relative to said nosepiece body, a second end directly engaging said cage and a recessed guide slot defined solely by said inner surface and extending along a longitudinal axis of said actuator; an independent guide fastener enclosed by said nosepiece body and including a first end and an opposing second end, said first end at least partially projecting into said fastener channel and slidably engaging an outside surface of said pin guide for retaining said pin guide in said nosepiece, and said second opposing end projecting into said guide slot and being slidable in said guide slot along said longitudinal axis and within said actuator while axially retaining said actuator on said nosepiece.
