Abstract
A chuck () may include a lock disk (), a ball retainer (), a lock sleeve (), a wedge pin (), and a pin drive spring (). When the lock sleeve () is disposed in the locked position, the wedge pin () may be positioned by the pin drive spring () in a wedged engagement between a pin engaging surface of the ball retainer () and a lock disk wall () of the lock disk () to prevent rotation of a first sleeve () and a nut () relative to a body () in a first rotational direction but permit rotation in a second rotational direction. When the lock sleeve () is disposed in the unlocked position, the wedge pin () may be positioned by the pin drive spring () such that the wedge pin () is not in the wedged engagement to permit rotation of the first sleeve () and the nut () in the first rotational direction and second rotational direction.
