Abstract: An apparatus and method for separating a pin tool from a shoulder tool, after the pin tool and shoulder tool have become welded together during a friction stir welding operation. In one exemplary embodiment a frame is used to support the shoulder tool. A fluid pressure actuating assembly is used for gradually exerting a force on the pin tool while the shoulder tool is held stationary within the frame. The gradually increasing force gradually breaks the weld and separates the pin tool from the shoulder tool without damaging the pin tool.

Abstract: A clamp device has a generally U-shaped body member, and a generally L-shaped body member. The L-shaped body member has a longitudinal portion, a transverse portion, and an anti-skid pod. A through hole and a guide groove are formed on the L-shaped body member. The U-shaped body member has a first leg, a second leg, and an anti-slip pod. An insertion block is disposed on the second leg. The insertion block is inserted in the guide groove. The second leg has a hexagonal hole and a round opening communicating with the hexagonal hole. A nut is inserted in the hexagonal hole. A bolt fastens the U-shaped body member and the L-shaped body member together.

Abstract: A machine vise has lateral cuttings outlets (10). Two wipers are provided on the slide (6). The first wiper (7) cooperates with the surface of a cylindrical region (2) of the spindle (1). The second wiper (8) clears the cuttings from the thread (4) of the spindle (1).

Abstract: The clamping device has two jaws between which a workpiece to be machined is immobilized on the table of a machine tool. Each jaw is supported by a carriage, and the carriages are coupled so as to move in a mirror symmetric fashion with respect to a plane orthogonal to the path of the carriages and at rest relative to the device. This avoids adding up tolerances of the shape of the workpiece with tolerance in the position of the clamping device relative to the machining tools.

Abstract: A vice has a pair of parallel, work-piece clamping jaw-members, which jaw-members are spaced laterally apart. The first jaw-member is a semi-rigid one, while the second jaw-member is completely slidable as an integral unit, and also allows for the two jaw-elements thereof of which it is comprised to be movable toward and away from each, whereby the second jaw-member may be used separately to hold a workpiece, and may be used in conjunction with the first jaw-member for assisting the first jaw-member in firmly and safely clamping a workpiece in order to provide a more stable holding of the workpiece during the working thereof. The second, floating jaw-member may be adjusted for holding the smaller-diameter portion of a long workpiece, while the fixed jaw-member holds and clamps the larger diameter portion of the same workpiece.

Abstract: Disclosed is a vise for clamping a workpiece in an adjusted position during operation on the workpiece by a tool, particularly the cutting wire of an electric wire cut discharge machine. For maintaining accuracy of the clamped workpiece and still occupying a minimum of space by the vise within the working range of the machine tool the vise is provided with a first fixed jaw and a second jaw movable along ways forming a reference surface. Wegding abutment surfaces and abutting surfaces are formed on the bed of the vise and on the second jaw, respectively, which engage during clamping the workpiece for preventing bending of the ways which allows a low profile construction of the vise.

Abstract: An apparatus for holding small articles comprises an elongated post, a rail member selectively slidably mounted at one end of the post at an angle relative to the longitudinal axis of the post, and a workpiece holding assembly mounted on the upper surface of the rail member. The workpiece holding assembly has a workpiece engaging device fixedly mounted at one end of the rail member and a selectively slidable jaw mounted on the upper surface of the rail member to allow holding workpieces of varying sizes and shapes between the slidable jaw and the workpiece engaging assembly.

Preferably, the bosses have through bores and are interconnected by respective ribs.

Abstract: A connector comprises two parts; namely, a keeper 10 in the form of a substantially flat plate having a slot 12 therein, and a bar 11 which locates in the slot. The keeper has a locking pin 13 which screws into a hole 14 in the keeper and engages the bar. The bar and slot are curved transversely so that pressure by the pin causes a greatly increased frictional grip between the slot and bar than would otherwise be the case if the bar and slot were flat.The connector has numerous uses such as a straight edged clamp as described in the preferred embodiment or for assembly of a kit of parts where a bar and keeper are incorporated into the respective parts to be joined.

Abstract: A free-standing clamping fixture and grinding wheel system for sharpening scissors and similar workpieces. The clamping fixture has an open frame and a pair of jaws located at the horizontal centerline of the grinding wheel, one of which is carried on a vertically adjustable yoke which also allows some lateral movement. The clamping fixture frame is angularly adjustable to the desired sharpening angle. The free-standing grinding wheel is provided with a moveable wheel guard which locks into place to open or close off an appropriate inlet of a grit removal system.

Abstract: A vise has an adjustable feature including a pair of adjustable members extending from a movable jaw toward another jaw. The adjustable members are movable independently of each other and independently of the movable jaw and permit clamping of uneven pieces or clamping of a piece off center between the jaws. Another adjustable feature permits the movable jaw to be held down during clamping operations.

Abstract: The vise system has a bracket section which can be secured to any flat horizontal work surface, particularly a drill press platen, with sliding and rotating degrees of freedom with respect to a bracket bolt. The bracket bolt threads into a hole in the work surface and can tighten down to rigidly hold the bracket section in position. A vise section, capable of clamping a work piece between fixed and movable jaws, is connected to the bracket section by a horizontally-oriented connecting bolt, about which the vise section can rotate, and which can be tightened to secure the vise section at any selected angle. The vise section has a rectangular cross-section, facilitating rapid self-indexing of angles 0, 90, 180, and 270 degrees with respect to the bracket section. The vise system is capable of being pivoted to a position in which the vise section extends beyond the edge of the work surface in order to accommodate work pieces in orientations which would otherwise interfere with the work surface.

Abstract: A combination vise that comprises a box construction frame that has three side surfaces for supporting the vise so that the jaws can be placed perpendicular to the table surface by laying the vise on either side and clamping it in position, or the jaws can be positioned on the top of the vise in a normal manner when the vise is set on its bottom.The three side surfaces of the vise which do not carry the jaws are machined so they will lay flat on a machine tool table and properly orient the jaws when the vise is clamped on any one of the three usable sides.
