A fastener driving tool that includes a lift mechanism for moving the driver from a driven position to a ready position. In one embodiment, the lift mechanism is mounted to a movable pivot arm, and the pivot arm is slightly rotated to allow the driver to drive a fastener; when the driver is to be lifted in a return stroke, the lifter subassembly is moved back into engagement with the driver, and multiple lifter pins contact protrusions in the driver to lift the driver from the driven position to the ready position. In another embodiment, the pivotable lifter floats along the driver, and 'releases' from contact only to prevent a jam or otherwise undesirable operating condition involving the driver; otherwise, the lifter remains nested in the tool's guide body during all operating states. A solenoid-operated latch also is provided to prevent the driver from moving downward (for driving a fastener).

Lift mechanism for framing nailer

A clenching adapter for use with automatic nailers tools is provided, which mounts to a nailer tool, and which extends behind a two-layer workpiece and curls the tip of a driven nail on the opposite side of the multiple-layer workpiece. The adapter includes a movable extension link that pivots on a proximal end, due to the action of an air cylinder actuator, and that pivoting motion causes an anvil mounted on its distal end to grasp the opposite (bottom) side of the workpiece, while also positioning the anvil to a location where it intercepts the nail that will be fired through the workpiece by the nailer tool. The anvil mechanism rotates from a 'relaxed' position that fits within a gap in the boards of a workpiece, to an actuated 'ready' position that receives and curls the nail, for clenching a multi-substrate workpiece. The actuations are automatically sequenced, in one embodiment.
