Abstract
A pneumatic fastener driving tool includes a gas cylinder, and a piston disposed in the cylinder in such a way that a centerline of the piston is coaxial with the cylinder longitudinal axis, and the piston is movable along the cylinder longitudinal axis between ready and driven positions. The tool includes a blade having a blade first end that is connected to the piston, and a blade second end that is configured to contact a fastener during a fastener driving operation. The tool includes a reset mechanism that returns the tool to the ready to fire configuration by translating the piston along the cylinder longitudinal axis to a location in which gas is compressed in the cylinder. The reset mechanism includes a ball screw device that drives the piston toward the ready position via a force that is concentric with the centerline of the piston.
