Abstract:
1. A chuck for use with a manual or powered driver having a housing and a rotatable drive shaft, said chuck comprising: a generally cylindrical body having a nose section and a tail section, said tail section having an internal cavity formed therein, said nose section having an axial bore formed therein, and said body having a first locking surface formed thereon; a nut disposed within said internal cavity, said nut being rotationally coupled to the drive shaft; a plurality of jaws movably disposed with respect to said body, each of said jaws being in communication with said axial bore and being operatively coupled to said nut so that rotation of such nut with respect to said jaws moves said jaws with respect to said body and said axial bore; a sleeve disposed about said body, said sleeve including a second locking surface configured to selectively engage and disengage said first locking surface; and wherein said body and said sleeve are axially movable with respect to each other between a first position in which said first and said second locking surfaces are engaged and a second position in which said first and said second locking surfaces are disengaged, said first position preventing the rotation of said body relative to said sleeve.
