Abstract
A molded chuck for a hand or powered driver including oblique jaws movable by rotation of a threaded nut engaged therewith to selectively clamp and release a tool.
Claims50
A chuck for use with a manual or powered driver having a rotatable drive shaft, said chuck comprising:
- a) an integrally molded body member having a nose section and a tail section, 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 tool engaging face formed on one side thereof and threads formed on an opposite outer surface;
- c) a nut rotatably mounted on said body member and in engagement with said threads on said jaws;
- d) a sleeve member in driving engagement with said nut whereby when said sleeve is rotated with respect to said body member, said jaws will be moved thereby;
- and
- e) a reinforcing nosepiece disposed around at least a portion of said nose section, said nosepiece including a portion engaging said nut to prevent said nut from disengaging the threads on the jaws because of excessive movement in the direction of the nose section.

A chuck for use with a hand or powered driver having a rotatable drive shaft, said chuck comprising:
- a) an integrally molded body member having a nose section and a tail section, said nose section having an axial bore formed therein and a plurality of angularly disposed passageways formed therethrough and intersecting said axial bore, said nose section having a reinforcing member co-molded therewith about at least a portion of its outer circumference;
- b) plurality of jaws slidably positioned in said angularly disposed passageways, each of said jaws having a tool engaging face formed on one side thereof and threads formed on an opposite outer surface;
- c) a nut rotatably mounted on said body member in engagement with said threads on said jaws;
- d) a sleeve member in driving engagement with said nut whereby when said sleeve is rotated with respect to said body member, said jaws will be actuated thereby;
- and
- e) a nosepiece extending over said co-molded reinforcing member, said nosepiece including a nut engagement portion for preventing said nut from moving in the forward direction an amount that would allow the nut threads to disengage from the jaw threads.

A chuck for use with a manual or powered driver having a rotatable drive shaft, said chuck comprising:
- a) an integrally molded body member having a nose section and a tail section, 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 and threads formed on an opposite outer surface;
- c) a nut rotatably mounted on said body member and in engagement with said threads on said jaws;
- d) a sleeve member in driving engagement with said nut whereby when said sleeve is rotated with respect to said body member, said jaws will be rotated thereby;
- and
- e) a reinforcing member pressed over said nose section of said body and extending substantially the entire distance from the forwardmost portion of the nose section to the area where the passageways intersect said axial bore, said reinforcing member including a portion engaging said nut to prevent said nut from disengaging the threads on the jaws because of excessive movement in the direction of the nose section.

An improved chuck for a manual or powered driver, said drill chuck comprising
- a) a body member having an axial bore and a plurality of angularly disposed passageways formed therethrough and intersecting said axial bore, wherein each of said passageways has an enclosed, substantially non-circular cross-section with respect to the longitudinal axis of said passageway;
- b) a plurality of jaws slidably positioned in said passageways, each jaw including a tool engaging portion and threads on an opposite outer surface, each of said jaws having a substantially polygonal cross-section with respect to the longitudinal axis of said jaw;
- and
- c) a mechanism for actuating said jaws to cause said jaws to hold and release a tool therebetween.

An improved body for a chuck, said body comprising:
- a) a molded forward body section having an axial bore and a plurality of angularly disposed jaw receiving passageways formed therethrough and intersecting said axial bore, each of said passageways having an enclosed non-circular cross-section with respect to the longitudinal axis of said passageway;
- and
- b) a rearward body section having a portion for mounting to the spindle of a drill or driver, said rearward section being integrally molded with said forward section.
A chuck for use with a manual or powered driver having a rotatable drive shaft, said chuck comprising:
- a) an integrally molded body member having a nose section and a tail section, said nose section having an axial bore formed therein and a plurality of angularly disposed passageways formed therethrough and intersecting said axial bore, and said tail section forming a multi-lobal gripping surface adapted to be gripped by a user's hand to maintain said body member in a fixed position while said nut is rotated with respect to said jaws;
- b) a plurality of jaws slidably positioned in said angularly disposed passageways, each of said jaws having a tool engaging face formed on one side thereof and threads formed on an opposite outer surface;
- c) a nut rotatable mounted on said body member and in engagement with said threads on said jaws;
- and
- d) a sleeve member in driving engagement with said nut whereby when said sleeve is rotated with respect to said body member, said jaws will be moved thereby.
