Abstract: A recoil absorbing gun mount (A) is disclosed which includes an elongated base (20) with a widened stabilized front end (22). A rear (24) of the base is supported by an incline adjusting leg (30) adjusted by a star wheel (32). Clamping jaws (40, 42) carry resilient gripping pads (44, 46) to frictionally clamp a gun (10) in the mount. The clamping jaws are attached by means of a pivot (C) which allows the clamping jaws to pivot in a yaw direction (56) and a roll direction (58). The pivotal movement in two degrees of freedom allows a clamping space (48) to be adjusted to accommodate different shapes and sizes of guns. The pivot includes angled slots (40f, 42f) formed in clamping jaws (40, 42). These angled slots slide over an operator rod (60) so that jaws (40, 42) may pivot relative to the base. A reduced clamping force is applied at (66) which is reduced from the force applied by operator rod ( 60).

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: A workbench of a foldable, portable nature includes a working surface formed by a pair of vise bars. The vise bars are operated by a pair of clamping screws which are so interconnected with a movable one of the bars by connections which allow limited lateral movement of a nut, carried by one of the screws, and the movable vise bar to permit one clamping screw to be rotated at a different speed than the other clamping screw. The vise bars are carried by a supporting structure formed by two frame members, means being provided for retaining the frame members at an acute angle to each other in an erected position of the workbench and for enabling the frame member to lie adjacent each other in substantially parallel planes, when the frames are in a collapsed position of the workbench.

Abstract: A clamping device is provided having a pair of outwardly curved arms with pivotally mounted clamping jaws at one end thereof. A rotatable leverage screw threadedly engages pivot members which are pivotally mounted at the other end of the arms. A rotatable fulcrum screw threadedly engages pivot members which are pivotally mounted on the arms intermediate the ends thereof, so that rotation of the fulcrum screw causes the arms to rotate about the pivot members associated with the leverage screw to open and close the jaws at a suitably high speed and rotation of the leverage screw causes the arms to rotate about the pivot members associated with the fulcrum screw to open and close the jaws with the force required to obtain a good clamping action.

Abstract: The invention is directed to a foldable, portable workbench having a work table and a support structure for supporting the work table. The support structure includes a pair of mutually spaced leg assemblies and each of these leg assemblies, in turn, includes a pair of legs pivotally connected at one end thereof to the work table. Articulated linkages pivotally interconnect, respectively, the two legs of each pair of legs to each other and at least one of the legs to the work table. The articulating linkages are connected so that the work table and leg structures are stacked in juxtaposition to each other when the workbench is in its folded position and, so that the other ends of the leg structures are spread apart from each other with the work table substantially transverse to the leg structures when the workbench is in the erected position.

Each transverse beam has an open side oriented in a direction parallel to the frame plane and a leg part extending in the length dimension of the transverse beam and having wall faces arranged parallel to the frame plane. A guide member is affixed to the movable vise jaw adjacent each transverse beam. The guide member, which has a part traversed by the spindle, is provided with a groove-like recess extending in the length dimension of the respective transverse beam. The leg of the respective transverse beam extends into the groove-like recess in the respective transverse beam.

The top structure includes a three part vice, one part being a first elongate vice member and the second and third parts together forming a second elongate vice member extending in side-by-side relationship with the first elongate vice member, the two elongate vice members having opposed clamping faces. A first vice operating arrangement causes movement of the clamping face of at least one vice member towards and away from the clamping face of the other vice member. A second vice operating arrangement causes relative movement of the second and third parts in a direction parallel to the direction of elongation of the vice members to permit clamping of objects between opposed further clamping faces of the second and third parts.

One or the other of the vise members is also connected to the supporting framework by a pair of vise-operating devices which can be operated to exert a force for moving the vise member a small incremental distance toward the first vise member under force to effect the clamping action. A folding leg structure is provided to support the top surface at convenient working height above the floor.
