ABSTRACT:
A portable power actuated fastener driving device having an improved actuating mechanism which includes a spring biased slide member mounted on the trigger member of the device for rectilinear sliding movement thereon between (1) an abutment position with respect to the actuating member and (2) a non-abutment position with respect to the actuating member. A spring biased slide moving member is mounted on the trigger member for movement with respect thereto between first and second positions and has a motion transmitting relationship with a movable member of the work contacting assembly and with the slide member for (1) causing the slide member to be in the non-abutting position thereof when the slide moving member is in the first position thereof so that when the trigger member is manually moved into the operative position thereof without the device being in cooperating relation with a workpiece, the actuating member remains in the inoperative position thereof and (2) enabling the slide member to be biased into the abutting position thereof when the movable member is moved into the operative position thereof so that a manual movement of the trigger member thereafter into the operative position thereof causes the slide member to move the actuating member into the operating position thereof.
