A fastener-driving tool has a housing including a combustion chamber, where the combustion chamber generates combustion for driving a fastener, and a processor associated with the housing and in communication with the combustion chamber. The processor is configured to cause an initial combustion in the combustion chamber and cause a fastener to be driven when a first actuation event and a second actuation event occur, and is configured to cause at least one subsequent combustion in the combustion chamber and cause at least one additional fastener to be driven when only the first actuation event occurs.

Reversion trigger for combustion-powered fastener-driving tool

A fastener-driving tool includes a housing and a workpiece-contacting element movable between a rest position and an activated position. The tool also includes a trigger connected to the housing and movable between a rest position and an activated position, a control valve including an actuating pin, an actuation lever movably connected to the trigger and movable between a rest position and an actuating position adjacent to the actuating pin, and a trigger control mechanism associated with the actuation lever and configured for moving and holding the actuation lever in the actuating position. In a powered mode, the trigger control mechanism causes the-actuation lever to move and remain in the actuating position such that the tool is actuated each time the workpiece-contacting element contacts a workpiece and moves to the activated position causing the actuation lever to contact the actuating pin and initiate an actuation of the tool.

Fastener-driving tool including a reversion trigger

A fastener driving tool including a housing, a cylinder enclosed by the housing, at least one sensor associated with the cylinder and a piston configured to reciprocate within the cylinder and having a driver blade depending therefrom. The tool includes at least one signal generator associated with the piston, where movement of the piston relative to the at least one sensor generates a signal. A controller is configured to receive the signal and indicate a fastening result based on the signal.

Fastener-driving tool including a fastening result detector

A fastener-driving tool includes a housing, a workpiece-contacting element movable between a rest position and an activated position, and a trigger movable between a rest position and an activated position. The tool includes an actuation lever movably connected to the trigger and a control valve including an actuating pin and an electromagnet where the actuating pin is movable between a rest position and an activated position. In a powered mode, the electromagnet is energized and attracts the actuation lever to the actuating pin and hold the actuation lever and the actuating pin in respective activated positions such that the tool is actuated each time the workpiece-contacting element contacts a workpiece. In a non-powered mode, the electromagnet is not energized such that the tool is actuated each time the workpiece-contacting element and the trigger are each moved from the rest position to the activated position in a designated sequence.

A nailer includes a power source including a piston reciprocating within a cylinder; a driver blade secured to the piston for common movement relative to a nosepiece; a magazine connected to the nosepiece for feeding fasteners sequentially for being driven into a workpiece by the driver blade; a fastener delay mechanism operatively associated with the magazine and configured for engaging a subsequent fastener and delaying advancement of the second fastener to the nosepiece until the driver blade returns to the pre-firing position after driving a leading fastener; and wherein the delay mechanism includes an electromagnetic solenoid with a reciprocating plunger connected to a pivoting cam member such that extension of the plunger causes the pivoting cam member to pivot into a blocking position between the fasteners.
