Abstract
Chuck for use with a manual or powered driver including a nut rotatably mounted on the chuck body, and in engagement with the threads of the chuck jaws. The chuck includes a self-contained anti-friction bearing assembly disposed between the nut and a thrust ring, as well as a generally cylindrical front sleeve member in driving engagement with the nut and overlying a nose section of the body of the chuck so that when the front sleeve member is rotated with respect to the body member, the jaws will be moved thereby. The chuck also includes a rust resistant decorative nosepiece as well as an improved nut retainer member.
Claims17
A chuck for use with a manual or powered driver having a rotatable drive shaft, said chuck comprising:
- a) a generally cylindrical body member having a nose section and a tail section, said tail section adapted to mate with said drive shaft of said driver and 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 positioned in said angularly disposed passageways, each of said jaws having a jaw face formed on one side thereof;
- c) a nut rotatably mounted on said body member and in engagement with threads on said jaws;
- d) a primary retainer member axially fixed on said body for maintaining said nut on said body;
- e) a generally cylindrical front sleeve member in driving engagement with said nut and overlying said nose section of said body member whereby when said front sleeve member is rotated with respect to said body member, said jaws will be moved thereby;
- and
- f) a secondary retainer member axially fixed on said body for maintaining said sleeve on said body.
A chuck for use with a manual or powered driver having a rotatable drive shaft, said chuck comprising:
- a) a generally cylindrical body member having a nose section and a tail section, said tail section having an axial bore formed therein to mate with said drive shaft of said driver and 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 positioned in each of said angularly disposed passageways, each of said jaws having a jaw face formed on one side thereof and threads formed on the opposite side thereof;
- c) a nut rotatably mounted on said body and in engagement with said threads on said jaws;
- d) a generally cylindrical sleeve member overlying said nose section of said body member and in driving engagement with said nut, whereby when said front sleeve member is rotated with respect to said body member, said jaws will be moved thereby;
- and
- e) a rust resistant nosepiece secured to said nose section of said body, said nosepiece being dimensioned and configured to prevent said sleeve from moving axially past said nosepiece in a direction away from said nut to a position where said sleeve does not overlay said nose section of said body.
