Patent number: 8419309Abstract: A pivoting ball mount provides four essentially equal and (generally) evenly spaced constraints on the ball, creating a ball and socket joint in which the “socket” is composed of four small constraining pads of equal size and equally spaced around the surface of the ball or sphere. If a sphere is constrained by four equidistant points, each point will exert the same amount of force on the sphere. If additional pressure is applied to one point, the pressure exerted by the other points will rise to match this increased pressure. The effect of constraining a smooth ball by four equidistant points is to create the equivalent of a ball and socket joint in which the force required to rotate the ball at a particular rate is about the same in any direction. The ball is constrained by four equidistant points such that the relative movement between the ball and housing is smooth and predictable in any direction.Type: GrantFiled: October 10, 2011Date of Patent: April 16, 2013Assignee: Wimberley, Inc.Inventor: David L.

Patent number: 7165762Abstract: An apparatus for holding and positioning a work piece in a desired position includes a hand-operated clamp for securing the apparatus to a fixed support, such as a table or workbench, a flexible, multi-segmented arm having one end secured to the hand-operated clamp and the opposite end pivotally secured to a vise. The vise includes a pair of jaws, a pair of essentially parallel tracks, and a screw mounted substantially parallel to said tracks. A small platform having resilient flanges snaps over and secures itself to the tracks. A number of configurations of the platform are possible depending upon the support structure of the electrical connectors or other assemblies which are being soldered or assembled. Work pieces of various shapes and sizes may be secured either to the platform or by the jaws of the vise.Type: GrantFiled: October 21, 2004Date of Patent: January 23, 2007Inventor: Christopher B.

Patent number: 7111836Abstract: The present invention is a workpiece positioner comprising a spherical ball having an aperture, a upper spherical dome housing having a groove through the housing beginning at the apex of the dome and extending down the side of the housing to approximately 90 degrees from the apex. The ball is positioned within the housing. A spherical seat is positioned against the ball. At least one tension disc spring is positioned against the seat. A radial braking means is positioned against the spring. A flange ring is affixed to the base of the housing securing the ball, seat, at least one spring and braking means in place within the housing. A base is secured to the braking means. An actuator lever is connected to the seat through the base. A cam and handle assembly is connected to the lever and a rod is affixed within the aperture of the ball.Type: GrantFiled: February 2, 2006Date of Patent: September 26, 2006Inventor: James C. West

Patent number: 6799755Abstract: A clamp for gripping a part or workpiece is provided in which the arms of the clamp securely engage the part before being locked in place relative to the body of the clamp. The clamp includes a body and first and second arms extending from the body. The clamp further includes a nut disposed in one of the two arms and a fastener extending through portions of both arms. Rotation of the fastener causes movement of the nut along a first axis which causes a corresponding movement in a pushrod disposed in the same arm as the nut along a second axis perpendicular to the first axis. The pushrod engages a plate disposed within the body of the clamp to lock the arms of the clamp relative to the clamp body.Type: GrantFiled: February 7, 2002Date of Patent: October 5, 2004Assignee: Dana CorporationInventor: Roger L. Stebelton

Patent number: 6641323Abstract: A cylindrical body has a first part-spherical socket portion in the top, fittingly receiving a ball. A ball retainer has a second part-spherical socket portion facing the first part-spherical socket portion and receiving the ball therein. A post has a proximal end fixed to the ball and extends radially outward from the ball and away from the body to a distal end, and has screw threads at the distal end to receive a fastener thereon for attachment of an object to the distal end of the post. The ball-in-socket mounting of the post enables freely swiveling the ball and thereby the swiveling the distal end of the post to an infinite number of loci in a spherical envelope centered at the center of the ball, as well as enabling the post, and any object mounted to the post, to be rotated on a radial line from the center of the ball to the location of mounting of the object to the post. The body has a hydraulic cylinder in the bottom receiving a piston.Type: GrantFiled: January 22, 2002Date of Patent: November 4, 2003Inventor: Stephen E. Ronsheim

Patent number: 6578801Abstract: A gripper or workpiece holder mounting bracket includes a center element and a pair of opposite end elements which are connectable to the center element via one or more fasteners. The mounting bracket defines a generally circular opening between the center element and one of the end elements and defines a second opening between the center element and other end element which has an arcuate or curved cross section, whereby a truncated spherical swivel member is pivotably secured therein when the bracket elements are secured together. The gripper or workpiece holder is pivotally secured within the generally circular opening, while the swivel member receives a generally cylindrical support structure therethrough. Adjustment of a clamping force at either or both of the openings of the mounting bracket may be accomplished via loosening of a single fastener.Type: GrantFiled: January 8, 2001Date of Patent: June 17, 2003Assignee: Delaware Capital Formation, Inc.Inventor: Keith S.

Patent number: 6575443Abstract: A swivel-base work platform is disclosed that comprises a hemisphere unit rotatably disposed within a base unit, wherein a work piece is secured to a work surface of the hemisphere unit and is manipulated to a variety of positions. The swivel-base work platform further comprises a hard-stop disk disposed at a lower end of the hemisphere unit, which engages the base unit in order to limit rotation of the hemisphere unit and the work piece. Further, the size of the hard-stop disk may be varied to adjust the range of motion of the hemisphere unit. Preferably, the work piece is secured to the work surface of the hemisphere unit using a vacuum source.Type: GrantFiled: July 24, 2001Date of Patent: June 10, 2003Assignee: The Boeing CompanyInventor: Thomas J.
