Publication number: 20080141753Abstract: A ferrule securing assembly including a die set assembly for reducing a cylindrical ferrule. The die set assembly having a female die and a male die. The female die having a female die opening sequentially defined by a tapered section, a parallel section, and a concave seat. The male die having a concave die face with at least two lateral edges, a medial area, and a radius of curvature. The male die is receivable in the female die opening to move the ferrule through the tapered section so as to forge the ferrule into a substantially oval shape, to move the oval shaped ferrule through the parallel section, and to compress the oval shaped ferrule between the concave die face and the concave seat to forge the oval shaped ferrule into a substantially cylindrical shape.Type: ApplicationFiled: December 14, 2006Publication date: June 19, 2008Inventors: William A. Wightman, James C. Clingerman

Patent number: 7340936Abstract: Apparatuses and methods for an improved handheld crimping tool for crimping a wire. The handheld crimping tool includes a head portion having a crimping device positioned adjacent a first end thereof. The crimping device may have an adjustable die cavity to facilitate crimping wires of various diameters. The crimping tool further includes a handle portion having a gripping portion suitably configured to be manually grasped. In one embodiment, the head portion is operable to be rotated relative to the handle portion to position the crimping device in a selected orientation and may be maintained in the selected orientation by a biasing mechanism. The crimping tool further includes a drive mechanism operable to actuate the crimping device. In one embodiment, the drive mechanism may be operable to convert rotational motion to reciprocating motion that generates a linear crimping motion in the crimping device.Type: GrantFiled: June 13, 2005Date of Patent: March 11, 2008Assignee: Shear Tech, Inc.Inventor: Ian Gregg

Publication number: 20080047319Abstract: The present invention provides a tool being used to crimp a ring onto a pipe joint, which includes two half-die members having each bore openings and a recess formed at their rear end portion for receiving a body member to be connected therewith by dowell pins, and further at their front end portion is formed a recess for receiving a threaded rod coupled to a clamp bolt. The threaded rod is engaged therein a threaded bore formed thereon a bushing passing through two bores located thereof each side of the lower half-die member. The clamp bolt is blocked therein the bushing by a spring pin to be engaged therethrough a hole formed therewith and through a hole formed therein the threaded rod. Further, the both half-die members are disposed in alignment with the bore openings for receiving the ring that is crimped onto the pipe joint by the use of a handle having at each end portion a notch to prevent the handle to be pulled out of the clamp bolt.Type: ApplicationFiled: July 31, 2006Publication date: February 28, 2008Inventor: Jacques Thibault

Patent number: 7320240Abstract: A device, such as an inner race of a torque converter's overrunning clutch, is formed by powder metallurgy. The race includes oil grooves and chamfers formed in each face by forging. The oil grooves on the first face open onto the chamfer. The chamfer on the second face is interrupted at the oil grooves such that each oil groove opens onto the diametral surface. A forge assembly for forming the race includes a die assembly including a discontinuous lower chamfer tool, an upper punch including groove tools and a continuous chamfer tool, and a lower punch including groove tools and radially extending teeth disposed at the oil grooves and capable of extending into the gaps of the lower chamfer tool. A method for forming the race includes employing the die assembly to forge the oil grooves and chamfers into the preform and remove flash by conventional grinding processes.Type: GrantFiled: September 13, 2005Date of Patent: January 22, 2008Assignee: GKN Sinter MetalsInventor: Jack E. Pederson

Publication number: 20070283741Abstract: A crimp or press tool is provided that includes two pivotally connected jaw members that can be selectively drawn toward one another in order to crimp or otherwise press a fitting onto a pipe or other workpiece. The tool uses a tightening assembly that enables the application of oppositely directed rotational forces to thereby prevent or at least significantly reduce the potential for imparting undesirable torque moments into the pipe or workpiece.Type: ApplicationFiled: June 5, 2007Publication date: December 13, 2007Inventors: Paul D. Bernstorf, Steven K. Morris, Jonathan M. Iwamasa, Michael H. Putre, Paul W. Gress

Patent number: 7290431Abstract: A pneumatically operated rivet squeezer is described, having features that allow for the miniaturization of a squeezer to a size smaller than portable rivet squeezers presently available. A first feature of the invention is that a return spring is accommodated within the squeezer housing by embedding the spring diametrically partially within a cavity in an internal wall of the housing and diametrically partially within a cavity in a jaw of the squeezer. A second feature of the invention contributing to miniaturization is that the squeezer utilizes a wedge having a very high mechanical advantage during the final stage of squeezing action, and a novel two curve surface for applying force to arms of the squeezer.Type: GrantFiled: January 12, 2007Date of Patent: November 6, 2007Assignee: U.S. Industrial Tool & Supply CompanyInventor: Boris Spivak
