Patent number: 9221105Abstract: A chuck including a body having a tail section and a nose section defining an axial bore. A plurality of jaws are movably disposed with respect to the axial bore and a nut is in threaded engagement with the jaws. A sleeve engages the nut so that rotation of the sleeve moves the jaws. A first ring defines a plurality of teeth and a second ring is rotatable relative to the nut over a limited arc and defines at least one pawl. In a first state, the second ring is non-rotatable relative to the first ring in both the opening and closing directions, and in a second state the first and second rings are rotatable about the body, and the second ring is rotatable relative to the first ring in the closing direction.Type: GrantFiled: April 14, 2014Date of Patent: December 29, 2015Assignee: Apex Brands, Inc.Inventors: Bach Gong, J.

Patent number: 7997587Abstract: A chuck with a generally cylindrical body having a tail section configured to receive a drive shaft of a driver and a nose section having an axial bore formed therein. A plurality of jaws is movably disposed with respect to the body. A nut is rotatably mounted about the body and operatively engages the jaws. A sleeve is non-rotatably coupled to the nut. A shield cap is rotatably secured about the nose section of the body. The chuck also includes a first ring and a second ring that rotates relative to the nut over a limited arc. One of the first ring and the second ring defines a ratchet and the other defines at least one deflectable tab that is biased toward and engages the ratchet.Type: GrantFiled: July 6, 2010Date of Patent: August 16, 2011Assignee: Jacobs Chuck Manufacturing CompanyInventors: Bach Gong, J.

Publication number: 20060279048Abstract: A chuck for use with a manual or powered driver having a generally cylindrical body having a nose section and a tail section, the tail section being configured to receive the drive shaft of the driver and the nose section having an axial bore formed therein. A plurality of jaws are movably disposed with respect to the body and in communication with the axial bore. A nut is rotatably mounted about the body and is in driving engagement with the jaws so that rotation of the nut in a closing direction moves the jaws toward the axis of the axial bore and rotation of the nut in an opening direction moves the jaws away from the axis. A shield cap is rotatably secured about the nose section of the body. The chuck also includes a first ring and a second ring, the second ring rotating relative to the nut over a limited arc. One of the first ring and the second ring defines a ratchet and the other of the first ring and the second ring defines at least one deflectable tab that is biased toward and engages the ratchet.Type: ApplicationFiled: June 9, 2005Publication date: December 14, 2006Inventors: Bach Gong, J.
