Open Access Stud Gripping Tool
Open Access Stud Gripping Tool
US Patent:
4611513, Sep 16, 1986
Filed:
Nov 19, 1985
Appl. No.:
6/799591
Inventors:
Richard H. Young - Billerica MA
Edward T. McLaughlin - Wilmington MA
Edward T. McLaughlin - Wilmington MA
International Classification:
B25B 1350
US Classification:
81 532
Abstract:
Stepped roller pins roll within stepped lobes formed around the interior wall of a hollow cylindrical casing. A hollow cylindrical retainer or simple ring retainer hook into a recessed groove around the middle of the roller and interact with ridges or grooves in the casing to retain the rollers within the lobes. The retainer fits within the limits of movement of a larger diameter section of the roller so that maximum contact is made between the rollers and a smooth stud shaft which is encircled by the casing to any desired extent. The rollers move along the lobes until they lock tight to grip the stud shaft for threading or unthreading. The casing is provided with wrench gripping faces around the exterior. A wrench grips the casing from the side to operate it leaving both ends of the casing open to admit the stud shaft.

US Patent:
5235878, Aug 17, 1993
Filed:
Jun 23, 1992
Appl. No.:
7/905121
Inventors:
Richard H. Young - Billerica MA
International Classification:
B25B 1350
US Classification:
81 532
Abstract:
A circumferential bead for preventing pin rollover is disposed on a retainer insert mounted in the shell of a stud gripper socket and spaced from the inner surface of the shell. The shell has at least one cam surface on its inner surface and there are roller pins disposed for rolling motion on each cam surface between the cam surface and the retainer insert. Each roller pin includes a circumferential retainer groove; the circumferential bead on the retainer insert engages the grooves on the pins; the bead has a curved contour associated with each cam surface for defining a gap which, intermediate the ends of the cam surface, is at least as wide as the pin diameter less the groove depth to permit the pin to freely roll along the associated cam surface, and which is less than the pin diameter to prevent the pin from falling out of of the shell, and which gap at the ends of the cam surface is narrower than the diameter of the pin less the depth of the groove to pinch the groove and prevent the pin from rolling beyond the ends of its associated cam surface.
