Patent number: 6435521Abstract: 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.Type: GrantFiled: December 12, 2000Date of Patent: August 20, 2002Assignee: Power Tool Holders IncorporatedInventors: Stephen W.

Patent number: 6168170Abstract: A chuck is provided for use with a manual or powered driver, such as a drill. The chuck has a body member with angularly disposed passageways formed therethrough. A plurality of jaws are slidably positioned within the angularly disposed passageways. The jaws grip upon a tool shank inserted into the body member. A nut is rotatably mounted on the body member and has nut threads defined on an inner circumference thereof in engagement with the jaw threads. A sleeve member is in driving rotational engagement with the nut whereby when the sleeve is rotated with respect to the body member, the jaws are also moved within the passageways. A rotational stop is defined between the nut and jaws wherein upon the jaws reaching a predetermined position within the passageways, further rotation of the nut in an opening direction is prevented. The stop comprises a radially extending surface defining an end of the nut threads. The radially extending surface contacts a side surface of at least one of the jaws.Type: GrantFiled: January 30, 1998Date of Patent: January 2, 2001Assignee: Power Tool Holders IncorporatedInventors: Kevin C. Miles, Christopher B. Barton, William H. Aultman

Patent number: 5913524Abstract: A chuck for use with a manual or powered driver having a drive shaft is provided. A generally cylindrical body has a forward section and a rearward section, the rearward section adapted to mate with the drive shaft of the driver. A gripping mechanism is actuatable to a closed position in which the gripping mechanism axially and rotationally retains a tool with respect to the body and to an open position in which the gripping mechanism does not so retain a tool. An annular nut is disposed about the body and has a threaded portion in threaded engagement with the gripping mechanism so that rotation of the nut about the body in a closing direction actuates the gripping mechanism to the closed position and rotation of the nut in an opening direction, opposite the closing direction, actuates the gripping mechanism to an open position.Type: GrantFiled: October 8, 1997Date of Patent: June 22, 1999Assignee: Power Tool Holders, Inc.Inventor: Christopher B.

Patent number: 5816582Abstract: Chuck for use with manual or powered driver having rotatable shaft, the chuck including a body member and jaws slidably positioned in angled passageways formed in the body. The chuck further includes a nut rotatably mounted relative to the body member and in engagement with threads on the jaws. A generally cylindrical front sleeve member is disposed in driving engagement with the nut and overlying the nose section of the body so that when the front sleeve member is rotated with respect to the body, the jaws will be moved thereby to grip the shaft of a tool. A spring member is biased to engage the sleeve member and is disposed selectively rotatably with respect to the nut. When the nut is tightened, the spring member becomes locked to the body member and restrains the nut from loosening during vibration of the chuck in use for its intended purpose.Type: GrantFiled: December 6, 1996Date of Patent: October 6, 1998Assignee: Power Tool Holders Incor.Inventors: Stephen W. Steadings, Christopher B. Barton

A generally cylindrical sleeve member is disposed in driving engagement with the nut and overlying the nose section of the body so that when the sleeve member is rotated with respect to the body, the jaws will be moved thereby to grip the shank of a tool. A pawl member is biased to engage the sleeve member and is disposed selectively rotatably with respect to the body member. When the nut is tightened, the pawl member can be disposed to become nonrotatable with respect to the body member and restrains the nut from loosening during vibration of the chuck in use for its intended purpose.Type: GrantFiled: October 2, 1996Date of Patent: April 21, 1998Assignee: Power Tool Holders IncorporatedInventors: Christopher B.
