Patent number: 11618131Abstract: An embossing device that serves for preparation of a combined form-fit and friction-fit clamping of a workpiece in a respective clamping chuck. The embossing device includes jaws having embossing teeth that are formed on insertion bodies. The insertion bodies include a penetration edge respectively with which they penetrate into the workpiece surface in order to create a depression with defined dimensions. For this a workpiece contact surface is formed on the insertion body, preferably in the proximity to the bar-like projection that stops the penetration process of the bar-like projection as soon as the workpiece contact surface gets in contact with the workpiece surface during the execution of the embossing process. Then the force required for movement of the jaw increases considerably from which a control device generates a switch-off signal for the operation device.Type: GrantFiled: March 25, 2021Date of Patent: April 4, 2023Assignee: LANG TECHNIK GMBHInventors: Guenter Lang, Philipp Lang

Patent number: 6244582Abstract: A system for an extension device that attaches to hand screw clamps and similarly configured clamps. Hand screw clamps have two jaw elements that are interconnected by two threaded shafts. As the threaded shafts are turned, the jaw elements can be biased toward one another in a variety of configurations. The system includes a first tubular element having an open end. Two opposing slots are present on the first tubular element that extend inwardly a predetermined distance from the open end. The open end of the first tubular element is sized to receive a first of the jaw elements of the hand screw clamp, wherein the threaded screws of the hand screw clamp pass into the slots. The system also includes a second tubular element having an open end and two opposing slots that extend inwardly a predetermined distance from that open end. The open end of the second tubular element is sized to receive a second of the jaw elements therein.Type: GrantFiled: September 24, 1999Date of Patent: June 12, 2001Inventor: Dante A. Marcolina

Patent number: 6217014Abstract: A work stop for use on a machine vise is received in a jaw plate for such vise and is securely locked in position. The work stop is fixed in a groove that is machined into a top edge of the jaw plate or jaw, with a member extending over the edge of the jaw plate and adjacent the face of the jaw plate that is used for clamping, a workpiece. This permits the workpiece to be slid against the stop before being clamped. The jaw plate is removably mounted onto a fixed jaw, and is located precisely relative to the fixed jaw so that the jaw plate with the work stop attached can be removed, and then replaced when the same part is to be machined again.Type: GrantFiled: January 6, 2000Date of Patent: April 17, 2001Assignee: Kurt Manufacturing Company, Inc.Inventor: Ingo E. Wolfe

Patent number: 6196536Abstract: An improved vise and an attachment for a conventional vise is disclosed that permits a user of the vise to machine all sides of a workpiece gripped between the jaws of the vise without having to remove the workpiece from the vise and incur operational downtime and expense. A plurality of grip blocks are removably attached either to the vise directly, or to a grip set attachment for the vise. The grip blocks may be selectively installed on either the vise or grip set at those areas which require holding power, and not installed from those areas along the gripped sides of the workpiece that the user desires to access. With a portion of the grip blocks selectively removed from the vise or grip set, the user can machine all sides of a gripped workpiece, including substantial portions of the sides of the workpiece gripped by the vise.Type: GrantFiled: March 8, 2000Date of Patent: March 6, 2001Inventor: Paul H. Hintze

Patent number: 6170814Abstract: A method for attaching a jaw to a vise-like workholding apparatus. The method includes placing the jaw member onto a support member of the workholding apparatus in a first direction that is perpendicular to a worksurface of the workholding apparatus. The jaw member is placed such that at least a portion of the support member is received within a cavity in the jaw member in a first released position. The method also includes applying a first axial force in a first axial direction to the jaw member to cause the jaw member to move axially in the first axial direction to a second position wherein it is retained on the support member.Type: GrantFiled: March 17, 1998Date of Patent: January 9, 2001Assignee: Chick Workholding Solutions Inc.Inventors: George R. Swann, Eric R. Moore, Edward S. Paris

Patent number: 6170813Abstract: The present invention relates to a vise for holding a workpiece. The vise includes a base supporting a moveable jaw, a fixed jaw, and a mechanism for moving the moveable jaw toward the fixed jaw. Each jaw includes a working surface, the working surfaces being disposed in facing relation and including at least two slots formed vertically spaced apart. Each slot is horizontally aligned with a slot in the opposing working surface. A selected pair of horizontally aligned slots each receive an insert for positioning the workpiece a distance from the base of the vise. The user's selection of the pair of horizontally aligned slots for reception of the inserts determines the position of the workpiece relative the base.Type: GrantFiled: July 21, 1999Date of Patent: January 9, 2001Inventor: Jerald A. Bowers

Patent number: 6152435Abstract: A machine vise has incorporated into it a pair of collet jaws that allows for the machining of top surfaces and ends of a held part. The collet jaws are secured to each of the clamping blocks on the machine vise. The collet jaws include at least one collet pocket shaped into the inside surface of each collet jaw. The collet pockets are designed to receive collet pads which are shaped to hold a generally cylindrical part with varying diameters. By having more than one collet pocket within each collet jaw, several different sizes of collet pads can be utilized at the same time and a part with varying diameters can be held securely in place within the machine vise.Type: GrantFiled: July 31, 1998Date of Patent: November 28, 2000Assignees: Lloyd D. Snell, Mark Bly, Joseph Green, Jeff Vanik, D. J. OpdahlInventor: Lloyd D. Snell

Patent number: 6089815Abstract: A basket assembly for holding a vehicle wheel rim. The basket assembly includes a basket adapted to hold the wheel rim, and a pair of pads connected to the basket. At least one of the pads is adjustable between a first position, in which the pads do not capture the wheel rim within the basket, and a second position, in which the pads are effective to capture the wheel rim within the basket. The basket assembly is useful in an apparatus for transferring wheel rims between metal forming stations during manufacture of the wheel rims.Type: GrantFiled: February 23, 1998Date of Patent: July 18, 2000Assignee: Hayes Lemmerz International, Inc.Inventor: Larry A.

Patent number: 6079703Abstract: This is a system/method of clamping or securing or connecting one or more objects together in a wide variety of ways with the main means being a specifically designed bar and mated slot combination. While the main embodiment is the "Handy Table" project, there are many other ramifications of this invention. The bar and slot design can be altered to perform many other tasks where some way of attaching one or more objects to another need be accomplished. The main embodiment is, in my estimation, the most advanced type of work or project surface. The combination of a tri-sectional work surface, adjustable in a variety of ways, in size, in tilting, in multi-angle clamping capability, in precision height adjustment, and in the ability to transport the object being worked on easily, plus the addition of accessaries that enhance the overall capabilities of the "Handy Table", make it useable by many different professions and by the average project worker, be it man or woman, young or old.Type: GrantFiled: October 17, 1997Date of Patent: June 27, 2000Inventor: Alex Benjamin Chavez, Jr.
