Abstract: A vise for holding small objects. It is particularly useful as a fly tying vise. It comprises a support bearing a housing having a rotatable central arbor carried in low friction bearings. The preferred form has a hub mounted at each end of the arbor. One hub houses a clutch or other locking device. The other hub bears a clamping arrangement having fixed and moveable members with distal jaw portions adapted to hold an object such as a fishhook. The clamping arrangement has a longitudinal axis essentially parallel to but off-axis from the longitudinal axis of the arbor. The axis of the arbor does not pass through the jaws of the clamping arrangement. This permits a hook to be held in the vise with its shank lying on the axis of rotation of the arbor. In this way body thread or other dressing can be rapidly and accurately applied as the fly is created. Jaw members have essentially parallel and planar opposing faces with the maximum opening being controlled by an adjusting screw.

Abstract: The device comprises a generally L-shaped angle plate or base plate bearing a first jaw on the shorter leg of the "L", fixing plates and a slider capable of being shifted along the base plate and bearing a second jaw. The base plate is fixed at three points to fixing plates and is adjustable with respect to the fixing plates by means of vertical adjusting screws mounted in the base plate and acting upon supports movably resting against the fixing plates. Side or lateral adjusting screws acting against a pin attached to one of the fixing plates permit the base plate to effect a limited angular displacement about a ball disposed in the region of the base plate defined by the intersection of the legs of the "L". The device permits an accurate positioning and orientation of a workpiece relative to the wire of a spark erosion machine and to the direction of this wire in its working position.

Abstract: Adjustable pipe clamp holders may be fixedly positioned within existing apertures on the work surface of a workbench. The holders are designed for locking engagement with pipe clamps so as to lock the pipe clamps to the workbench. Through the adjustable rotatable positioning of the clamp holders in certain selected apertures, the pipe clamps may be securely locked in any desired angular position on the workbench, thus to facilitate the desired positioning of a workpiece within the jaws of the pipe clamp.

Abstract: The present invention relates to a vise for securely supporting a workpiece relative to a fixed support. The vise includes a base member which is secured relative to the fixed support. A clamp assembly is rotatably mounted with respect to the base member and includes a pair of jaw members one member of which, except for the relative rotative movement between the clamp assembly and the base member, is fixed relative to the base member. The second jaw member is pivotally interconnected to the first jaw member. Both jaw members have a workpiece engaging surface formed thereon with the engaging surfaces arranged in a facing relation to one another. The vise further includes a threaded handle pivotally mounted on the second jaw member and cooperating with the fixed jaw member for pivoting the jaws relative to one another to move the workpiece engaging surfaces toward one another whereby a workpiece positioned between the surfaces will be securely supported.

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 vise is cantilever mounted to a workbench, projects forwardly thereof, and is disposed below the extended plane of the workbench table top. The vise includes a pair of U-shaped brackets, secured to the underside of the table top, and a pair of tubular beams slidably received in the respective brackets. Each of the beams is selectively indexed to its cooperating bracket, thereby providing a "coarse" adjustment. A fixed rear vise jaw is disposed on top of the beams, transversely thereof; this rear vise jaw is secured to the brackets and abuts against the lower portion of the longitudinal front side of the table top. A movable front vise jaw is mounted on top of the beams, transversely thereof, and may be moved in a non-parallel relationship with respect to the fixed rear vise jaw for clamping tapered workpieces therebetween.

Abstract: The strut tool has a frame with a pair of clamp faces on the front thereof and a pair of clamp hooks extending therebetween. A screw pulls the clamp hooks towards the clamp faces so that the strut clamp can engage on and clamp on a slotted strut to temporarily support structure with respect to the strut while the structure is being secured to the strut.

Abstract: A clamp for use in holding a wing panel stringer to a header on a wing panel jig includes a clamp base affixed to the header. A stringer locator, which has a pair of clamp-engaging surfaces, is mounted for rotational movement on the clamp base. The first clamp-engaging surface is oriented generally parallel to the rotational axis of the locator while the second surface is a locus of lines that are preferably generally perpendicular to the first surface and form a convexly arcuate second surface. A J-shaped clamping member is slidably and rotationally mounted in the clamp base. The terminus of the curved portion of the clamping member engages the exposed surface of a stringer to hold it tightly against the first and second clamp surfaces.

Abstract: A vise-like C-clamp with adjusting screw and wherein two elongated square bars are fixedly attached to one jaw thereof and the clamping end of the adjusting screw whereby a pair of gripping heads may be selected from a group of variously shaped heads and oppositely and interchangeably arranged on each of the bars. The clamp may be hand held or adjustably mounted in a supporting base for gripping and positioning variously shaped work pieces in horizontal, vertical, and angularly held positions while work is performed thereon.

Abstract: A fly-tying vise has a vise portion for gripping a fly-tying hook supported by a vertical support post above a clamp portion for gripping the free edge of a tabletop. A jaw assembly of the vise portion has a pair of hook-clamping jaws opened and closed by a thumb screw. The jaw assembly cooperates with a spring-biased detent to allow rotation of the jaws without changing their closure setting through application of a combined axial and torsional pressure to the thumb screw. The clamp portion includes a sleeve slidably adjustable along the support post and a pair of clamping arms, one fixed to and the other slidable along the sleeve to adjust for different tabletop thicknesses. The slidable arm carries a thumb-screw-operated bearing disc which creates a bind between the slidable arm and sleeve to hold such arm in an adjusted position when the disc and fixed arm bear against opposed surfaces of a tabletop.
