Abstract
The present invention relates generally to pneumatic ratcheting mechanisms and in particular to a device to aid in shank spindle retainment during ratchet resetting. According to the present invention, at least one recess is provided in the shank spindle of a ratchet head to receive a spring therein. The end of the spring is compressed against an interior surface of the ratchet head to frictionally retain the shank spindle and pawl of the ratchet during the resetting stroke of the ratchet yoke.
