Abstract: A portable fastener driving device of the conventional pneumatic type having an improved actuating mechanism including an acutating member mounted for movement from a normal inoperative position into an operative position for initiating the movement of the fastener driving means through a fastener driving stroke, a contact trip mounted for movement from a normal inoperative position into an operative position in response to the movement of said device into cooperating engagement with a workpiece, a trigger mounted for manual movement from a normal inoperative position into an operative position and an enabling structure operatively associated with the actuating member, the trigger and the contact trip for (1) enabling movement of the trigger into its operative position when the contact trip is in its inoperative position without movement of the actuating member into its operative position, (2) enabling movement of the trigger into its operative position when the contact trip is in its operative position to effect movement of the actuating member into its operative position, and (3) enabling movement of the contact trip into its operative position when the trigger is in its operative position without movement of the actuating member into its operative position.
