  • Patent number: 5954321
    Abstract: A rotating jewelry clamp includes a base and a rotatable housing supported thereby such that the housing can be freely rotated relative to the base. The housing threadably receives a clamp assembly with a hollow outer sleeve and a reciprocable piston extending therein. The outer sleeve terminates in an overhanging stationary jaw and the piston includes a movable jaw which mates with the stationary jaw to form a clamp. A lower portion of the piston engages a coil spring within the rotatable housing to urge the piston upward toward the stationary jaw so that jewelry pieces are clamped into position between the movable jaw and the stationary jaw via tension caused by spring action. Insertion and removal of jewelry pieces is accomplished by grasping an insulated handle protruding from the piston and urging the piston downward within the outer sleeve against the spring action, thus separating the movable jaw and stationary jaw.

  • Patent number: 4894896
    Abstract: Precision centering device useful for positioning items in a predetermined position has first and second halves which are held within a frame. The first and second halves are maintained against retaining walls within the frame by resilient material. The bottom portion of the halves extends from the bottom of the frame and each has a tapered edge which face each other in order to hold the item to be positioned. The top of the halves are maintained within the frame by a resilient structure which allows the halves to move in a vertical position. The halves which accomplish the positioning do not have to be made from precision parts. As the parts wear the centering precision is maintained since the parts are mirror images of each other made from a common piece of stock material.

  • Patent number: 4874156
    Abstract: This combination holding tool and vise allows the operator, using hands and a foot pedal, to insert and adjust one or more work pieces between vise jaws before allowing spring pressure to hold the work pieces between the jaws in the holding tool mode. The arrangement permits the holding tool assembly with the work piece(s) to be transferred intact to another work station. Instead, the work piece(s) may be firmly gripped in their held position by advancing a rigid mechanical stop against one of the jaws, so that the holding tool now becomes a conventional vise. If desired, the vise assembly with the work piece(s) may be transferred to another work station. The combination has obvious advantages over a separate holding tool and vise in speeding up production and assembly operations, such as lower cost, ability to perform added operations on the work piece, and simplicity, so that it can be operated by handicapped, partially disabled people.

  • Patent number: 4848760
    Abstract: An apparatus for clamping tire tubes for repair thereof. The apparatus includes a base with a frame extending upwardly therefrom. A mandrel is attached to the upper end of the frame. A vertically movable actuating rod is positioned adjacent the frame and biased downwardly by a spring, the force of which may be adjusted. The lower end of the actuating rod is connected to a foot pedal for overcoming the force of the spring and raising the rod. The upper end of the rod has a yoke assembly connected thereto. The yoke assembly has a substantially U-shaped yoke forming a pair of upwardly extending arms, each arm having a substantially horizontal clamping bar connected thereto. The yoke is preferably at least partially flexible so that the arms will deflect outwardly as a result of the downward force exerted by the spring when the clamping bars engage a tire tube positioned on the mandrel.
