Abstract
A chuck device for use with a manual or powered driver has a body member with a plurality of angularly disposed passageways formed therethrough. A jaw is slidably positioned in each passageway. Each jaw has a tool engaging face formed on one side and threads formed on the opposite side. The jaws are threadedly engaged with a rotatable nut mounted on the body member. A sleeve member is in rotational engagement with a nut whereby rotation of the sleeve causes the nut to rotate and the jaws to advance or retract within their respective passageways. Each jaw and its respective passageway has a unique matching profile different from the other jaws and respective passageways so that the jaws cannot be interchanged with different passageways in the chuck.
Claims25
A chuck for use with a manual or powered driver having a rotatable drive shaft, said chuck comprising:
- a 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;
- 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 thereof;
- a nut rotatably mounted on said body member and in engagement with said threads on said jaws;
- a sleeve member in driving rotational engagement with said nut whereby when said sleeve is rotated with respect to said body member, said jaws will be moved thereby;
- and
- wherein each said jaw and its respective said passageway have a unique matching profile different from said other jaws and respective passageways so that said jaws cannot be interchanged with different said passageways.
A chuck for use with a manual or powered driver having a rotatable drive shaft, said chuck comprising:
- 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, each of said passageway having a profile that is different in at least one characteristic from said other passageways;
- 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 thereof, each of said jaws further comprising a keyed surface that is different on each of said jaws wherein said keyed surface allows said jaw to slide within only one respective said passageway;
- a nut rotatably mounted on said body member and in engagement with said threads on said jaws;
- and
- a sleeve member in driving rotational engagement with said nut whereby when said sleeve is rotated with respect to said body member, said jaws will be moved thereby.
A power tool having a rotatable drive spindle and a chuck configured thereon for holding a tool bit to said drive spindle, said chuck further comprising
- 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, each of said passageway having a profile that is different in at least one characteristic from said other passageways;
- 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 thereof, each of said jaws further comprising a keyed surface that is different on each of said jaws wherein said keyed surface allows said jaw to slide within only one respective said passageway;
- a nut rotatably mounted on said body member and in engagement with said threads on said jaws;
- and
- a sleeve member in driving rotational engagement with said nut whereby when said sleeve is rotated with respect to said body member, said jaws will be moved thereby.
