Chuck with internal nut

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;
• a nut disposed within said internal cavity, said nut including a central bore;
• a spindle including a forward portion extending into said central bore of said nut and a rear portion being configured to receive said 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;
• a sleeve disposed about said body;
• and wherein said nut is axially movable with respect to said spindle between a first position and a second position, said nut being rotatably fixed to said spindle in said first position and non-rotatably fixed to said spindle in said second position, wherein when said nut and said spindle are in said second position with respect to each other, said body is rotatable relative to said sleeve.

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 having a central bore extending axially therethrough, said nut being disposed within said internal cavity and being rotationally coupled to the drive shaft;
• a spindle including a forward portion extending into said central bore and a rear portion configured to receive 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, and
• wherein when said body and said sleeve are in said first position with respect to each other, said nut is rotatable relative to said body and said spindle.
