Abstract: An interface component is provided for use in combination with a clamp or compressive tool imparting a compressive force against respective planar contact surfaces of two components being joined at a miter joint. The interface features an elongated member having a projection projecting away from a top surface in a substantially circular path. The curved surface provides a means to redirect the compressive force communicated against said curved surface to the miter joint at a substantially normal angle.

Abstract: An attachment for use with a clamp having a pair of jaws operable to clamp a workpiece therebetween, such attachment comprising a body member of such size as to be accommodated in a space between one of the jaws and the workpiece. The body member of the attachment has a first contact surface adapted to bear against a surface of the workpiece and a second, opposite contact surface adapted to bear against one of the jaws. The second contact surface is so configured as to enable the attachment body member to be substantially universally rockable relative to the jaw engaged by such attachment body member, thereby enabling the body member to occupy a position in engagement with and substantially parallel to that surface of the workpiece engaged by the attachment body member.

Abstract: An apparatus for gripping objects comprising a first jaw having a first support member and a first support plate that is slidingly attached to the support member with respect to a first direction or motion. The apparatus is also comprised of a second jaw that has a second support member and a second surface plate attached to the second surface member. Additionally, the apparatus is comprised of a structure holding the first jaw and the second jaw such that the first jaw and the second jaw can move in a second direction toward or away from each other to grip or release the object, respectively. In a preferred embodiment, the second surface plate is fixedly attached to the second support member and the first direction is perpendicular to the second direction. The sliding action of the first support plate acts to reduce the effective frictional force between the object and jaws to facilitate stable grasping.

Abstract: A composite panel consists of a natural stone layer (1) and a reinforcing layer (13) that has a fibre layer (2) embedded in synthetic resin, and at least one layer (3) of synthetic resin. The fibre layer (2) serves as tensile reinforcement and the layer (3) of synthetic resin serves as compression reinforcement for the natural stone layer (1), so that the composite panel can absorb both positive and negative bending moments. The synthetic resin layer (3) is reinforced, for example, with a fine-mesh glass fibre textile (6) that faces towards the tensile reinforcing fibre layer (2) and an adjacent glass fibre mat (8). In order to produce the composite panels, natural stone panels that have been cut to a greater thickness are coated on both sides with the reinforcing layer (13). A plurality of coated natural stone panels are then arranged so as to be equally spaced on their center planes, and then simultaneously divided.

Abstract: A cassette type part clamping member holding precision parts of small size to very close tolerances. The parts are clamped in a manner so that they are securely held but are not damaged. The cassette mounts relatively easily made, low cost, and useful reference bar for providing a reference surface against which the parts are clamped and also against which a sensor will operate during an operation such as grinding to insure that a straight grind cut is made. The cassette that holds the part clamping members and the reference bar, and a separate outer cassette holder fixture which provides reference surfaces for supporting the reference bar holding it in position accurately and without affecting the preload on the clamping members is mounted on the tool table. The cassette can be removed from and replaced into the holding fixture without releasing the parts.

Abstract: A nipple chuck for holding a pipe nipple blank in a power driven threading machine is comprised of three arcuate sleeve segments engaged between the jaws of the threading machine chuck. The segments are internally threaded at the front ends thereof and are pivotally supported adjacent the rear ends thereof such that the internally threaded front ends are manually pivotal radially of the nipple chuck axis. In use, the segments are closed about the threaded end of the nipple blank which is then securely grasped by radial engagement of the machine chuck jaws with the segments. Following threading of the unthreaded end of the nipple blank, the nipple chuck is removed from the machine chuck jaws, and the segments are manually pivoted to an open position to release the nipple.

Abstract: A vise square device for use between the jaws of a conventional vise to engage an irregular or inclined workpiece under clamping force to firmly seat and secure the workpiece, comprises first and second engaging plates having confronting recesses for receiving a spherical element, and at least one resilient member secured between the plates to provide a unitary device, the resilient member being deformable to accommodate relative movement between the plates and the spherical element to allow multi-directional plate adjustment to accommodate workpieces of irregular or inclined configuration. Serrations are preferably provided on the article-engaging plate face for improved securement of a workpiece.

Abstract: A jaw for use in a clamp in which there are two relatively movable jaws on a frame to clamp board stock between them, said jaw including a body and a face plate having a rib abutting the face of said body as a horizontal fulcrum for rocking of the face plate, and a spring device engaging both said body and the rear side of said face plate on at least one side of said rib and constituting a resilient mounting of said face plate on said jaw body providing for even distribution of the clamping force to the upper and lower portions of the boards, one form of the resilient mounting means including two brackets held on the jaw body by a tension spring connecting the brackets and extending in a groove across the front side of the face plate, each bracket having resilient arms engaging the back of the face plate at opposite sides of said fulcrum.

Abstract: The present invention relates to a clamping device of the kind comprising at least two jaws, at least one of which being movable to clamp one or more workpieces between the jaws, and at least one lever being pivotable in relation to the jaws and having two arms, one of which being actuated when moving the jaws towards each other in order to tend to pivot the lever and the other being arranged, when actuating said first arm, to exert a clamping force on the workpieces substantially perpendicularly to the direction of movement of the movable jaw, wherein said first arm of said lever is located between one of the jaws and the workpieces in order to be subjected to a compressive force via said workpieces when moving the jaws towards each other.
