Patent number: 4489926Abstract: The workpiece supporting and clamping universal device of the invention comprises essentially an outer ring which can be secured to a base plate and into which are inserted a plurality of discs arranged concentrically in one another except for a disc which is eccentric with respect to the others, the discs being each provided with a column so that the columns are thus apt to cover all the points of any given surface by means of relative rotation of the discs.Type: GrantFiled: September 8, 1982Date of Patent: December 25, 1984Assignee: Automatique Industrielle S.A.Inventor: Jean-Pierre Blatrix

Patent number: 4484381Abstract: An assembly comprising a board 1 and a mechanism 17 for clamping a marginal portion of the board adjacent an edge between two opposed substantially flat parallel walls 7a. The mechanism 17 is mounted on a major surface 19 of the board 1 and includes a spring strip 21 extending longitudinally along the mechanism, and having corrugations transverse to its length. An elongate cam 27 extends along the length of the strip 21, overlying the strip, and being supported for rotation about its longitudinal axis. Rotation of the cam 27 causes expansion of the mechanism 17 in a direction normal to the surface 19, limitation of the expansion by the walls 7a leading to compression of the corrugations in the strip 21.Type: GrantFiled: July 19, 1982Date of Patent: November 27, 1984Assignee: Marconi Avionics LimitedInventors: Stafford M. Ellis, James P. M. Keay

Patent number: 4477064Abstract: Several versions of a tooling plate clamp are disclosed. Each comprises a retainer pin a circular part of which extends outwardly from the face of the plate. An eccentric clamp body rotates on the circular part of the retainer pin and is held against the face of the plate, or against a spacer, by an overhanging head on the pin. The clamp body can be cylindrical to exert a lateral force on the workpiece or conical so that it exerts lateral and downward forces simultaneously. In one version, the clamp body has an edge which engages the workpiece along a narrow line of contact rather than over a wide area. The clamp body may also be a hold-down clamp with two oppositely directed helical overhanging surfaces.Type: GrantFiled: June 9, 1982Date of Patent: October 16, 1984Inventor: Mario DiGiulio

Patent number: 4381105Abstract: There is disclosed a clamp which is particularly adapted for use in high-temperature applications in which arms bearing clamping faces are mounted on a flat bar in a manner such that they can be released to slide along the bar and clamped in any desired position. One arm has a fixed clamping face and the other arm has a movable clamping face movable toward the other. The latter is affixed to the free end of an elongate member adapted to reciprocate back and forth in the other arm and to be moved toward the first clamping face by a spiral cam. Means is provided for locking the arms to the backbone member and for locking the spiral cam in the clamping position.Type: GrantFiled: May 8, 1980Date of Patent: April 26, 1983Assignee: Gordon W. HueschenInventors: Otis W. Goff, Melvin J. Goff

Patent number: 4369956Abstract: A self-centering fixture makes use of an air actuated motor which is drivingly rotated in one direction. The fixture has a pair of levers pivoted to a base. As the motor is actuated, a cam positioned between the longer arms of each lever rotates and acts to move the longer arms apart. Thus, on the other side of the pivot, jaws on the shorter arms move towards one another to grasp the workpiece. The workpiece is released by reversely activating the motor. Since the cam is counteracted by springs which pull the long ends together, the jaws open.Type: GrantFiled: November 17, 1980Date of Patent: January 25, 1983Inventor: Orvil R. Aronson

Patent number: 4367776Abstract: A machine for the manufacture of reinforcing bodies for concrete pipes and the like, which comprises longitudinal bars and wire wound about the longitudinal bars. Two coaxial discs are provided. A main disc, fixedly mounted on a base frame, carries radially displaceable guide pieces for the longitudinal bars. A support disc, mounted on a carriage movable in the direction of the axis of the main disc, carries a clamping device for clamping the ends of the longitudinal bars at a selectively different spacing from the axis of the disc. The clamping device comprises elongate clamping members which constitute radially extending clamping slits. The clamping slits open and close in parallel over their entire length. The length and position of the clamping members correspond to the range of adjustment of the guide pieces on the main disc.Type: GrantFiled: October 23, 1980Date of Patent: January 11, 1983Assignee: MBK Maschinenbau GmbHInventor: Georg Pfender

Patent number: 4342449Abstract: A plate stack clamping element is formed of adjacent leaf springs preformed to diverge where they extend beyond the plate stack. Compression of the diverging portions creates large area contact clamping force against the plate stack.Type: GrantFiled: May 25, 1979Date of Patent: August 3, 1982Assignee: Varta Batterie AktiengesellschaftInventors: Joachim Illmann, Heribert Fullfgraf

Patent number: 4294147Abstract: A ram driven tube cutting apparatus of the double cut type in which sections of tubing are successively severed from a continuous length thereof by a notching cut followed by a severing cut, includes improved mechanism for clamping the tubing during the cutting process. A pair of opposed, complemental die jaws are mounted on slides controlled by spaced cam followers carried by the slides. A reciprocating wedge cam engages and forces the cam followers apart to move the slides thereby closing the jaws on the tubing. One of the cam followers comprises a roller mounted on an eccentric shaft which may be selectively rotated to adjust the clearance between the die jaws. The other cam follower is spring loaded toward the cam within a slide mounting provided in its slide and automatically shifts to an overload position to avoid damage to the mechanism when foreign objects become lodged between the die jaws.Type: GrantFiled: February 7, 1980Date of Patent: October 13, 1981Inventor: John J. Borzym

Patent number: 4222490Abstract: An apparatus for storing multiple pairs of skis in bottom-to-bottom facing arrangement and in a generally upright orientation, with the skis contacting one another at forward and rearward contact zones, includes a generally upright support on which individually adjustable sets of upper and lower clamping assemblies are positioned. Both the upper clamping assembly and the lower clamping assembly of each set are operable to apply a releasable clamping force against the top surfaces of the associated pair of skis. At least one of the clamping assemblies is movable toward and away from the other one, whereby the clamping forces may be applied at spaced locations relative to the forward and rearward contact zones so as to restrain warping of the stored pair of skis. The support is rotatably mounted on a dish-like receptacle for melted snow.Type: GrantFiled: January 23, 1978Date of Patent: September 16, 1980Inventor: Theodore N. Wood, Jr.
