Abstract
A chuck includes a driver disposed on a chuck body and in engagement with the jaws so that at least one of rotation and axial movement of the driver with respect to the body opens or closes the jaws. A first detent is disposed in the body in communication with the jaws. At least one of the jaws defines a catch at a predetermined position so that the catch engages the first detent when the jaws are at a predetermined position on the body with respect to a chuck bore.

A chuck for use with a manual or powered driver having a drive shaft, said chuck comprising:
- a. a generally cylindrical body having a nose section and a tail section configured to rotate with said drive shaft, said nose section having an axial bore formed therein and a plurality of angularly disposed passageways formed therethrough and intersecting said axial bore;
- b. a plurality of jaws slidably received in respective said angularly disposed passageways, each of said jaws having a jaw face formed on one side thereof;
- c. a driver disposed on said body member and operatively engaged with said jaws;
- d. a generally cylindrical sleeve rotatably mounted about said body and operatively engaged with said driver so that relative rotation between said body and said sleeve drives said jaws toward or away from said axial bore, depending on the direction of said rotation;
- and
- e. a first detent disposed in one of said body and at least one of said jaws in communication with a catch formed on the other of said body and at least one of said jaws,
