US Patent:

53223055, Jun 21, 1994

Filed:

Nov 25, 1992

Appl. No.:

7/981777

Inventors:

Kenneth Cross - Utica MI
Ralph J. Gonnocci - Rochester Hills MI

International Classification:

B23B 3112

US Classification:

279124

Abstract:

A power chuck includes a body, a plurality of work engaging jaws, a plurality of rocker arms carrying the jaws, and plurality of swivel mountings connecting the rocker arms to the body. The power chuck also includes a plurality of slide members connected to and matingly engaging the rocker arms and reciprocable actuator disposed centrally of the rocker arms and operatively cooperating with the elide members. Reciprocatory movement of the actuator along the slide members rocks the rocker arms in the swivel mountings and moves the jaws radially relative to each other.

Appl. No.:

6/622000

Inventors:

Kenneth O. Cross - Utica MI

Assignee:

N. A. Woodworth Company - Detroit MI

International Classification:

B23B 522
B23B 534

US Classification:

279123

Abstract:

A top jaw adapted for mounting on and attachment to the master jaw of a conventional work holding chuck and simultaneously during attachment thereof to be located radially against a fixed stop by a double T-nut of unique configuration, the latter being movable by an actuator screw in T-slots provided in the jaws, one portion of the T-nut and the complementary T-slot in the top jaw in which it is mounted being inclined with respect to and sloping toward the interface between the top and master jaws so that tightening of the T-nut by the actuator screw forces the top jaw radially against the stop and simultaneously axially against the mating surface of the master jaw, the taper angle of T-nut and the lead angle of the screw threads mutually cooperating to lock the top jaw on the master jaw in use.

Appl. No.:

5/957470

Inventors:

Paul Toth - Allen Park MI
Kenneth O. Cross - Northville MI

Assignee:

N. A. Woodworth Company - Detroit MI

International Classification:

B23B 3130
B23B 3300

US Classification:

82 40R

Abstract:

A work driver chuck having face and actuator plates interconnected by the pivot shafts of work holding cam jaws carried by and journaled for rotative movement in the face plate. Although normally centered on the rotational axis of the chuck, the assembly of plates and jaws is released for limited universal free floating movement during the actual work clamping operation to compensate for eccentricity of or surface irregularities in the workpiece. The actuator plate is slidable relative to the face plate and is operative as it moves to turn the jaws angularly into or out of engagement with the work.
