Patent number: 5799531Abstract: A crimping device for crimping end fittings on hoses and tubes includes a base ring and a pressure ring. The base ring includes a frustoconical inner surface in which is positioned a die assembly which, at its opposite end, abuts a portion of the pressure ring. When the pressure ring is pushed toward the base ring, the dies converge, crimping the fitting to the hose or tube. In order to properly locate the hose or tube, a locator pin is affixed to the pressure ring by an L-shaped bracket. The locator pin, pressure ring and crimping die assembly form a tool package which, upon being initially set, does not have to be reset for subsequent uses. The tool package can be stored while other tool packages of a similar configuration are set, used and then stored for subsequent use. In this way, the irritation and resulting inefficiency of having to continually reset tooling is minimized.Type: GrantFiled: September 17, 1996Date of Patent: September 1, 1998Assignee: Dana CorporationInventors: Eric D. Orcutt, Dean D. Fritz

Patent number: 5650684Abstract: In a rotating body or machinery that is equipped with at least one such rotating body, the power loss resulting from the inertial force, which is an internal force caused by the rotation of the rotating body, contributes to mechanical inefficiency, as well as being the cause of unnecessary heat generation, unnecessary machine strength requirements, increased weight, and increased costs. Provided are low-loss machines and engines that essentially eliminate or greatly reduce the power loss due to the aforementioned inertial force. The rotating body of this invention, or machine which is equipped with at least one such rotating body, greatly reduces or essentially makes zero the power loss resulting from the inertial force generated by the rotating or rocking motion of the rotating body due to its poor mass distribution. This inertial force is an internal force of a new concept which excludes the centrifugal force.Type: GrantFiled: July 14, 1994Date of Patent: July 22, 1997Assignee: Newstein lab., Inc.Inventor: Noriyuki Suganuma

A circular shaping die (16) having an annular groove on its periphery and rotatable about its own axis, which is parallel to the axis of the main die, is supported on a mounting (16) so that it is rotatable about the axis of the main die. The mounting (16) is drivable by a reduction gear (20,22,24,26). An abutment surface (32) is formed on the body of the pipe bender and the pipe clamp has a pipe receiving bore therethrough and an outer surface including at least two faces (50,58) each selectively engageable accurately with the abutment surface to position temporarily the pipe clamp with respect to the pipe bender, the faces (50,58) extending at an angle to one another when viewed along the axis of the pipe receiving bore.Type: GrantFiled: January 6, 1988Date of Patent: November 22, 1988Assignee: M.

Patent number: 4757705Abstract: A plate processing device for use in a machine with a vertically acting ram; has a guide device mounted on the frame and a guide member which is pressed to a sliding surface of the ram. The guide member freely rotates around the centerline of the first vertical shaft and also freely rotates around the centerline of the second shaft perpendicular to the first shaft and parallel to the sliding surface and is constructed so that it follows the sliding surface of the ram. Also, a back gauge for the work is buffered against the shock of abutment with the workpiece and may be backed away from the workpiece. A pressing plate for the workpiece is supplied by a high pressure and a low pressure plunger, which are vertically actuated to provide a noiseless operation.Type: GrantFiled: May 7, 1986Date of Patent: July 19, 1988Assignee: Amada Company, LimitedInventors: Yoshitaka Arima, Hidekatsu Ikeda, Toshiaki Kunihiro, Chuo Tobita

Patent number: 4736614Abstract: A contact support device is described. The device is attachable to a contact crimping tool and places the electrical contact in position adjacent the jaws of the tool. The device includes a cavity for supporting the contact. The cavity provides polarization of the contact therein and prevents rotation of the contact during crimping.Type: GrantFiled: April 24, 1986Date of Patent: April 12, 1988Assignee: Thomas & Betts CorporationInventor: Charles T. Fryberger

Patent number: 4700559Abstract: An apparatus for repairing a deformed, yieldable body of a motor vehicle. The apparatus includes a frame on which a raised platform is secured. To restrain the vehicle during the application of a restoring force, various appliances are attached at any location about the outer boundary of the platform and coupled to the motor vehicle. The appliances are adapted to be attachable to and releasable from the motor vehicle without requiring its movement. To apply the force necessary to restore the deformed, yieldable body of a motor vehicle, the apparatus includes pull-towers supported on and movable along a track provided by the frame. Each pull-tower includes a compact power head which can be moved vertically up or down the pull-tower. Activating the power head produces the force used in restoring the deformed, yieldable body of the motor vehicle.Type: GrantFiled: October 1, 1986Date of Patent: October 20, 1987Inventors: Byron A. Larson, John J. Molteni

Patent number: 4637242Abstract: A locator device for a tool with crimping dies for cable shoes has at least one track for accommodating the contact portion of the cable shoe, a stationary stop at the end of the track and a movable stop at a selected location along the track. For treating cable shoes with longer contact portions, the movable stop is lifted from the track so that the stationary stop is operative, and when treating cable shoes with shorter contact portions the movable stop is put in place. The device is preferably made as a readily mountable accessory to the crimping tool.Type: GrantFiled: April 11, 1984Date of Patent: January 20, 1987Assignee: C. A.

Patent number: 4630462Abstract: A tool for crimping cable shoe terminals having an affixing part and a contact part onto the ends of electrical conductors has a pair of jaws provided with at least one pair of co-operating crimping dies and hinged together by a pivot pin. On the same pivot pin is mounted a rocker arm carrying for each pair of crimping dies a chamber accommodating the contact part of a terminal to be crimped. The rocker arm is affected by a position-controlling force such as friction at the location of mounting, and by suitably located dog means so that it makes a move, after the crimping operation has been terminated, by which the terminal, now crimped on a conductor, is lifted from the crimping die so that it readily can be removed from the tool.Type: GrantFiled: March 12, 1985Date of Patent: December 23, 1986Assignee: C. A. Weidmuller GmbH & Co.Inventors: Hans Wiener, Hans Undin
