Patent number: 6619101Abstract: A head for a crimping tool assembly comprises a generally “C” shaped body which can withstand repeated tensile forces. The “C” shaped body comprises an elongated beam portion and a first arm extending in a given direction from a first end of the beam portion and a second arm extending in the given direction from an opposing end of the beam portion. The beam portion has opposed first and second elongated sides, with the plane of the first and second sides extending generally parallel to the given direction. The beam portion also has an inside elongated third side extending transversely of the given direction between the first and second sides. The beam portion further includes an outside elongated fourth side extending transversely of the given direction between the first and second sides. The third and fourth sides of the beam comprise continuous walls of a given thickness.Type: GrantFiled: April 19, 2002Date of Patent: September 16, 2003Assignee: FCI Americas Technology, Inc.Inventors: Thomas Faucher, Gordon L. Stelzer, Christopher G. Chadbourne, John D. LeFavour, Alexander Shlopak

Patent number: 6401515Abstract: A method for operating a hydraulic pressing device, for example, a pipe clamping device, that includes a stationary part and a moving part. The hydraulic pressing device also includes an automatically actuating return valve. The moving part of the hydraulic pressing device is displaced relative to the stationary part until a predetermined pressure is reached. At that point, the moving part returns automatically and completely back into its initial position, which is released as a result of the predetermined pressure being reached. The moving part is biased into its initial position by means of a return spring and, on removal of the restoring force, returns automatically back into its initial, closed condition.Type: GrantFiled: June 6, 2001Date of Patent: June 11, 2002Assignee: Gustav Klauke GmbHInventor: Egbert Frenken

Patent number: 6276186Abstract: The invention relates to a method for operating a hydraulic pressuring device with a stationary part (26) and a moving part (24), whereby the moving past (24) is moved relative to the stationary part (26) until a predetermined pressure is reached. In order to operate a hydraulic pressuring device of this type, for example a cable shoe (connecting) or riveting tool pressing device, whose handling is especially improved, the invention provides that moving part (24) returns automatically and completely to the initial position thereof when a predetermined pressure is reached.Type: GrantFiled: August 10, 1999Date of Patent: August 21, 2001Assignee: Gustav Klauke GmbHInventor: Egbert Frenken

Patent number: 6212932Abstract: A power assisted combination shear used for forming structural louvers in the crimped seam of structural steel decking comprises a frame supporting a pair of jaws which are opened and closed by means of an operator-controlled pneumatic cylinder. One jaw terminates in a blade, the other jaw has a corresponding die member. The blade and die have undercut reliefs in the root portions, which permit the louver to be formed without breaking through to the edge of the seam. The louver comprises a sheared portion in the form of a bowed tab bridging a corresponding window formed in the seam by the shearing of the tab. The interference between the louver and window provides a substantial increase in the lateral resistance (shear strength) of the crimped seam, thereby obviating the need to additionally weld or screw the seam to provide the necessary shear strength for even the highest stress applications.Type: GrantFiled: July 19, 1999Date of Patent: April 10, 2001Inventor: James R.
