Abstract:
1. A tool adapted to apply a torque to a work piece comprising: a ratchet gear adapted to transmit the torque to the work piece in either of a first or second rotational drive direction, wherein the first rotational drive direction is opposite the second rotational drive direction; a pawl mechanism adapted to engage the ratchet gear to selectively permit rotation of the ratchet gear in the first rotational drive direction and substantially prevent rotation of the ratchet gear in the second rotational drive direction, and selectively permit rotation of the ratchet gear in the second rotational drive direction and substantially prevent rotation of the ratchet gear in the first rotational drive direction; a reversing lever operably coupled to the pawl mechanism and adapted to selectively choose either of the first and second rotational drive directions for the ratchet gear; and an auto-shift mechanism including: wherein the disc is axially movable along the first driveshaft to shift the reversing lever upon rotation of the worm gear.
