  • Patent number: 7984913
    Abstract: A chuck including a cylindrical body with a nose section and a tail section, the nose section having an axial bore formed therein. A sleeve is rotatably mounted about the body. Rotation of the sleeve in a closing direction moves the jaws toward a longitudinal axis of the axial bore and rotation of the sleeve in an opening direction moves the jaws away from the longitudinal axis. An O-ring is disposed adjacent the sleeve in a plane that is transverse to the longitudinal axis. A bearing has a first race adjacent the body, a second race adjacent the sleeve and bearing elements therebetween. One race defines a ratchet and the other of the first race and the second race defines a pawl biased toward the ratchet. The O-ring biases the pawl toward the ratchet and when the pawl engages the ratchet prevents the second race from rotating in the opening direction with respect to the first race.

  • Patent number: 7976253
    Abstract: A chuck for use with a manual or powered driver having a housing and a rotatable drive shaft extending therefrom is provided. The chuck includes a generally cylindrical body member having a nose section and a tail section. Each of a plurality of jaws is slidably positioned in one of a plurality of angularly disposed passageways in the body. Each jaw has a jaw face formed on one side thereof and threads formed on the opposite side thereof. A nut is rotatably mounted on the body in engagement with the jaw threads so that rotation of the nut moves the jaws axially within the passageways. A locking member, in a first axial position, is rotatable with respect to the driver housing. In a second axial position, it operatively engages the housing and the nut so that the locking member is rotationally held to the housing and the nut so that the nut is rotationally held to the housing. The locking member is axially reciprocal between the first axial position and the second axial position.

  • Publication number: 20110062674
    Abstract: A chuck for use with a driver having a rotatable drive shaft, the chuck including a body having a nose section and a tail section, the tail section being configured to rotate with the drive shaft and the nose section having an axial bore. A plurality of jaws is movably disposed with respect to the body and in communication with the axial bore. A first sleeve is rotatably mounted to the body in operative communication with the jaws so that rotation of the sleeve moves the jaws either toward a longitudinal center axis of the axial bore or away from the longitudinal center axis. A second sleeve is rotatably mounted to the body and is movable between a first position in which the second sleeve is rotatably fixed to the body and a second position in which the second sleeve is rotatable about the body. The second sleeve moves in a direction transverse to the longitudinal center axis of the axial bore when moving between the first position and the second position.

  • Patent number: 7900937
    Abstract: A chuck includes a generally cylindrical body constructed of aluminum and a plurality of jaws moveably disposed with respect to the body in communication with the body's axial bore. A generally cylindrical sleeve is rotatably mounted about the body in operative communication with the jaws so rotation of the sleeve in a closing direction moves the jaws towards the axis of the axial bore and rotation of the sleeve in an opening direction moves the jaws away from the axis. A bearing has a first race adjacent the body, a second race adjacent the sleeve and at least one bearing element disposed between the first race and the second race. One of the first race and the second race defines a ratchet. The other of the first race and the second race defines a pawl biased toward the ratchet. The ratchet and the pawl are configured so that when the pawl engages the ratchet, the ratchet and pawl prevent the second race from rotating in the opening direction with respect to the first race.

  • Patent number: 7530576
    Abstract: A non-impact keyless chuck suitable for use with manual or powered drivers is disclosed. The chuck comprises a body which carries a rotatable split nut having a relatively fine thread and a plurality of slidable jaws, which may be identical, driven by the rotatable nut. An anti-friction bearing is disposed between the rotatable nut and a bearing thrust ring mounted on the body. A clutch or torque limiting mechanism is provided to limit the tightening torque to a predetermined value while the loosening torque may be limited or unlimited. The front sleeve, and rear sleeve, if used, may be formed from a structural plastic to reduce manufacturing costs. A relatively soft elastomeric grip boot may be placed on the front sleeve to improve the grip and temporarily restrain and center the tool during chuck tightening or loosening operations. A relatively soft elastomeric grip boot may also be placed on the rear sleeve, if used.
