  • Patent number: 6164635
    Abstract: An improved vise with a fixed jaw and a movable jaw which is guided by a lead screw to move along a pair of ways guiding the movable jaw. The movable jaw is adjusted to maintain a face which is precisely parallel with a face of the fixed jaw. The movable jaw is constructed of an upper component which travels on the ways, and a U-shaped lower member which inserts and telescopes into the upper component. The two jaw members contact at a chamfered face which cants or tilts the upper jaw member so that the movable jaw construction can be leveled. Leveling assures that the upper and lower jaw members cooperate, thereby interacting with a tapered face between the two to change the relative angle. In effect, the movable jaw face is maintaining precisely parallel and overcomes off center mounting of a workpiece.

  • Patent number: 6032940
    Abstract: A universal vise that has a movable and a fixed jaw that can be indexed at 90.degree. increments to provide for four separate work clamping surfaces on each jaw. The vise includes a vise screw driving a nut that drives the movable jaw in each of four indexed positions of the movable jaw. The nut provides a down pressure load on the movable jaw with a very low profile. The indexable jaws permit the vise to be adapted to hold four different types of products or workpieces. The movable vise jaw is guided with keys that protrude above the plane of the guideway surfaces of the vise, so that the nut can have a shield rib that completely fills the space between the guideway surfaces to prevent chips from building up in a recess between the rails formed with present vise jaw nuts. The movable jaw and the fixed jaw do not protrude toward the base of the vise beyond the plane of the guideway surfaces on the vise rails.

  • Patent number: 5984290
    Abstract: In a two station machining vise having a stationary, center jaw and movable opposing jaws, the interior of the vise body is totally enclosed to protect the working components from machining byproducts. The vise has a brake mechanism and an offset mechanism associated with one slide so that workpieces can be engaged and released sequentially. If the brake mechanism is not activated, the two movable jaws are moved simultaneously. With the brake mechanism engaged, one movable jaw is moved to position first and then the movable jaw having the brake and offset mechanisms connected therewith is subsequently moved into position. When the workpieces are to be released, the second movable jaw is first retracted the offset distance and then the first movable jaw must be completely retracted prior to any subsequent movement by the first movable jaw.

  • Patent number: 5730433
    Abstract: A tool for mating, clamping, and gluing under high pressure, two picture frame members, the ends of which have been precisely cut prior to clamping. This high pressure produces a stronger joint than is now available in existing clamps that only hold the adjacent times while the glue is setting. It also produces a faster glue setting time than conventional clamps since excess glue is squeezed out, thus increasing clamp efficiency by making it available sooner for the next glue joint. In addition, it embodies an optional vertical clamp, which, in conjunction with a transparent triangular plate, applies a vertical pressure on members that may have been slightly warped or inaccurately cut. The triangular plate is optionally used with complex profiles to distribute the pressure. This combination results in a tight aesthetic joint. Existing clamps on the market do not embody this feature.
