Patent number: 7008151Abstract: A power driver includes a motor and a spindle having a distal end thereof opposite the motor. The distal end has an axial bore formed therein. A gear assembly is disposed operatively between the motor and the spindle so that the motor rotationally drives the spindle through the gear assembly. A grip is mounted in the spindle in communication with the axial bore. A driver is mounted about the spindle in operative communication with the grip so that activation of the driver in a closing direction moves the grip radially toward the axis and activation of the driver in an opening direction moves the grip radially away from the axis.Type: GrantFiled: May 3, 2004Date of Patent: March 7, 2006Assignee: Jacobs Chuck Manufacturing CompanyInventors: Theodore G.

Patent number: 6648342Abstract: A chuck includes a generally cylindrical body having a nose section and a tail section. A plurality of jaws are movably disposed with respect to the body to and away from the chuck's axial bore. A generally cylindrical sleeve is in driving communication with the jaws. The sleeve engages the body or the jaws by a first set of interengaged threads so that relative rotation between the first threads drives the jaws toward or away from the chuck axis. The sleeve engages the body or the jaws by a second set of interengaged threads so that relative rotation between the second threads drives the jaws toward or away from the chuck axis. The first thread set defines a first pitch so that when the jaws close, the first threads rotationally lock in the closing direction. The second thread set defines a second pitch that is higher than the first pitch so that when the jaws close, the second threads are relatively rotatable in the closing direction.Type: GrantFiled: February 11, 2003Date of Patent: November 18, 2003Assignee: Power Tool Holders IncorporatedInventors: William H.

Patent number: 6354605Abstract: A chuck includes a generally cylindrical body having a nose section and a tail section. A plurality of jaws are movably disposed with respect to the body to and away from the chuck's axial bore. Each jaw includes a tool engaging surface facing, and generally parallel to the axis of, the axial bore. Each jaw includes a back surface opposite the tool engaging surface and a pair of planar side surfaces extending from the tool engaging surface toward the back surface. The side surfaces are disposed on either side of a plane that includes the axis. The side surfaces define an angle through the jaw between the side surfaces that is greater than 120°.Type: GrantFiled: March 10, 2000Date of Patent: March 12, 2002Assignee: Power Tool Holders IncorporatedInventor: William H.

Patent number: 6179512Abstract: A collet nut has a nut member for threaded engagement with threads on a collet holder. A sleeve member is rotationally coupled to the nut member in a first tightening mode of the collet nut. An annular ring is rotationally coupled to the sleeve member and rotationally coupled to the nut member in the first tightening mode. Facing ramped bearing surfaces are defined between opposing faces of the annular ring and the nut member and bearing devices, such as balls, are disposed between the opposite faces. In the first tightening mode, the nut member and the annular ring rotate as a unit. In a second tightening mode, the annular ring rotates relative to the nut member so that opposing high sections of the ramped bearing surfaces are brought rotationally closer thereby forcing the annular ring axially away from the nut member which imparts an additional axial force to a collet engaging member of the collet nut.Type: GrantFiled: May 29, 1998Date of Patent: January 30, 2001Assignee: Power Tool Holders IncorporatedInventors: Stephen E. Gibson, William H. Aultman

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: 6050741Abstract: A clamping device for holding a rotating tool or stationary object to a threaded shaft of a power tool or machine includes a body member having an annular ring configured therewith. The annular ring has at least two concentric ramped bearing surfaces defined on an inner axial face thereof. An operating ring is rotationally mounted on the body member and has an axial face with concentric ramped bearing surfaces defined thereon oppositely facing the bearing surfaces on the annular ring. The operating ring has a second axial face with at least one unramped bearing surface defined thereon. A flange member has an inner axial face opposite the operating ring second axial face. The flange member is axially movable relative to the body member and presses against and clampingly holds a rotating tool relative to a drive shaft upon manual rotation of the operating ring in a tightening direction. A bearing device is disposed between the ramped bearing surfaces of the annular ring and the operating ring.Type: GrantFiled: January 30, 1998Date of Patent: April 18, 2000Assignee: Power Tool Holders IncorporatedInventors: William H.
