Locking chuck

A chuck for use with a driver having a housing and a rotatable drive shaft extending therefrom, the chuck comprising:

• a generally cylindrical body having a nose section with an axial bore formed therein and a plurality of angularly disposed passageways formed therethrough and intersecting said axial bore;
• a plurality of jaws, each said jaw being slidably positioned in a respective one of said angularly disposed passageways and having a jaw face and threads formed thereon;
• a nut in operative communication with said rotatable drive shaft so that said drive shaft rotationally drives said nut, said nut engaging said threads on said jaws so that rotation of said nut with respect to said body axially moves said jaws within said passageways;
• and
• a sleeve selectively actuatable to
• a first axial position in which said sleeve rotationally locks said housing and said body with respect to each other, and
• a second axial position in which said sleeve permits relative rotation between said body and said housing,
• wherein said body is axially reciprocal with respect to said housing and said rotatable drive shaft.

• and
• means for locking said body to said housing, said locking means selectively actuatable to
• a first axial position in which said locking means rotationally locks said housing and said body with respect to each other, and
• a second axial position in which said locking means permits relative rotation between said body and said housing.
