Patent number: 7530576Abstract: 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.Type: GrantFiled: May 15, 2006Date of Patent: May 12, 2009Assignee: Jacobs Chuck Manufacturing CompanyInventors: Robert O. Huff, Paul T. Jordan, William F. Forquer

Patent number: 6914543Abstract: A method for detecting an absolute rotational position of an electromechanical device or the at least one component thereof comprising determining a first absolute position of the electromechanical device or the at least one component thereof based on a commutation index signal, obtaining a Z-index signal, and determining a second absolute position of the electromechanical device or the at least one component thereof based on the Z-index signal. The method initially determines a coarse rotational position of the electromechanical device such as a rotor or steering wheel based on the commutation index signal. When a device's position is first initialized by a commutation index signal before the Z-index pulse is detected, the device's position is re-initialized upon detection of the Z-Index pulse to provide a more accurate absolute device rotational position.Type: GrantFiled: June 3, 2002Date of Patent: July 5, 2005Assignee: Visteon Global Technologies, Inc.Inventors: John H. Floros, Nick Sarafopoulos, Paul T. Jordan

Patent number: 6520508Abstract: A tool receiver or chuck is provided which may receive a cutting tool, such as a router bit or the like, therewithin and non-rotatably retain the tool relative to a rotary driving device. The tool receiver includes a plurality of blades substantially encased within a conical surface. A biasing member biases the blades toward a narrow end of the conical surface such that the blades are biased in a tool engaging or operative position. The biasing member and conical surface thus bias the blades radially inward toward the cutting tool such that the blades engage the conical surface and the cutting tool. The tool receiver preferably includes a retaining member, which retains the blades within the conical surface and biases the blades radially outwardly toward the conical surface.Type: GrantFiled: August 30, 2000Date of Patent: February 18, 2003Assignee: Jordan Manufacturing Solutions, Inc.Inventor: Paul T.

Patent number: 5215317Abstract: A chuck has a spring connection between the nut which rotates to advance or retract the jaws and the control ring or sleeve which the user rotates to operate the chuck. The spring normally transmits tightening or loosening rotation from the sleeve to the nut. When the jaws contact a tool, however, the spring allows the sleeve to continue to rotate even though the nut is stopped by the jaw-tool contact. Continued rotation of the sleeve relative to the nut causes a cam mechanism interposed between these two elements to force the non-rotating nut axially forward. This applies a final tool-gripping force to the jaws.Type: GrantFiled: May 18, 1992Date of Patent: June 1, 1993Assignee: Jacobs Chuck Technology Corp.Inventors: Paul T. Jordan, Louis M. Shadeck, Robert O. Huff

Patent number: 5193825Abstract: The center of a collet having a plurality of individual gripper members resiliently spaced apart in an annular array and operated on by a frustoconical surface can be adjusted by displacing some of the gripper members more than others of the gripper members parallel to the axis with which both the annular array and the frustoconical surface are nominally concentric. This causes the frustoconical surface to produce greater radial displacement of some of the gripper members, thereby shifting the center of the collet transverse to the above-mentioned axis. An element transversely moveable relative to the axis causes displacement of some of the gripper members more than others.Type: GrantFiled: October 3, 1991Date of Patent: March 16, 1993Assignee: Jacobs Chuck Technology CorporationInventors: Roger J. Kanaan, Paul T. Jordan

Patent number: 5145194Abstract: A tool chuck suitable for use with manual or powered impact drivers is described. The chuck comprises a body which carries a rotatable nut and a plurality of slidable jaws, driven by the rotatable nut. An anti-friction bearing is disposed between the rotatable nut and a bearing thrust ring mounted on the body. The bearing thrust ring has a plurality of detents and may cooperate with a compression spring to prevent the chuck from loosening during operation.Type: GrantFiled: June 21, 1991Date of Patent: September 8, 1992Assignee: Jacobs Chuck Technology CorporationInventors: Robert O.
