    Abstract: A cantilever clamping device capable of clamping work pieces of variable sizes and shape is equipped with a quick release button at its fixed arm to release the threaded rod and hence the work piece. The Quick Release Cantilever Clamp utilizes a fixed arm and a movable arm with floating pads to clamp the work piece. Clamping action is achieved by turning the threaded rod, one end of which is connected to the movable arm and the other end is attached with a turning handle. Both the fixed arm and the movable arm are designed to have clamping teeth on the curved inner edges to clamp large size cylindrical work pieces and the floating pads are for smaller size cylindrical work pieces and work pieces of different shape and sizes. The fixed arm is equipped with two holes for attaching the optional base block to mount the clamp on a work surface.

  • Patent number: 5720096
    Abstract: A locking fence for a power tool such as a chop saw, or for a work surface of a workbench, is capable of being moved to a selected location on the chop saw base or work surface and oriented at a selected angular orientation relative to the chop saw blade. The fence is locked simultaneously in such location and orientation when an operator rotates a cam actuator to lift a first clamping member away from the fence, which in turn draws a second clamping member into clamping engagement with the underside of a workpiece support of the base, and which further forces a cam portion of the actuator against the fence. No tools are required to lock or unlock the fence. The fence defines an arcuate slot for enabling the angular orientation to be adjusted. The arcuate slot is maintained in juxtaposition to a slot formed in the work surface for enabling movement of the fence to its selected location on the workpiece support or work surface, by linking screws linking the slots.

  • Patent number: 5513838
    Abstract: A clamp is more versatile, less damaging, and able to apply a holding force directed from most any angle in its plane of action. This general work-holding clamp consists of several movable clamping units mounted on a circular frame. A clamping unit consists of a clamp screw, a small thumbscrew, and a base. The clamp screw serves its normal purpose, the thumbscrew holds the base in place on the frame, and the base connects the clamp screw to the frame. The circular frame carries all forces between the clamping units, and has a gap to improve versatility.

  • Patent number: 5427364
    Abstract: A screw clamp comprises a pillar (5), a backing arm (11) and a clamping arm (12), a clamping part (6) being connected with the backing arm (11) and/or with the clamping arm (12) and a respective thrust plate (7 and 8) being connected with the backing arm (11) and with the clamping arm (12) or, respectively, with the clamping part (6). In order to render it possible to exert forces on surfaces which are not parallel to each other the backing arm thrust plate (8) and/or the clamping arm thrust plate (7) are adjustable in angle, preferably because the backing arm (11) and/or the clamping arm (12) respectively consist of an arm bearing (1 and 2) and an arm shank (3 and 4) able to be turned in relation to it.

  • Patent number: 5350163
    Abstract: A clamping member (11) for a wood clamp (10) is provided and comprises two spaced engaging elements (14, 15), each shaped as right oval cylinders. The engaging elements are rotatably mounted to a support plate (17) and are arranged to slide relative to support plate in respective slots (16) which converge. A workpiece is arranged to be clamped between the engaging elements when it is moved in the direction in which the slots converge as movement of the workpiece causes the engaging elements to slide in the converging slots thus further gripping the workpiece and also rotate until such time as the engaging elements clamp the workpiece and prevent further movement of the workpiece.

  • Patent number: 5312097
    Abstract: A double C-clamp device is provided which consists of a pair of C-clamps, each having a fixed jaw and a moveable jaw and a pair of clamp bars. A fastening structure is for attaching the first clamp bar transversely between the fixed jaws and the second clamp bar transversely between the moveable jaws of the C-clamp. The C-clamps which are in a stationary spaced apart relationship can cause the clamp bars to come towards each other to hold a work piece which may be tapered an have irregular shaped contact surfaces.

  • Patent number: 5282610
    Abstract: A self-indexing vise 10 for clamping an angled workpiece 47 includes a pair of jaws 20, 32 capable of relative movement, a semi-cylindrical jaw insert 54 received in a recess 52 in one of the jaws 20, 32 and capable of pivoting to automatically conform to the contour of an angled workpiece 47. The jaw insert 54 is sized slightly larger than the recess 52 in which it pivots such that when the vise 10 is loaded, a press fit forms between recess 52 and jaw insert 54 which locks the insert 54 into position.

  • Patent number: 5188347
    Abstract: The present invention relates in one aspect to a compressible and/or deformable microtome object holder. The object holder may be in the same or similar shape as a wide variety of previous object holders, comprising a specimen plate having a textured or grooved surface and a shank structure. The holder may further comprise a ball element on the opposite end of the shank structure from the plate. In this instance, the ball element serves as the means of mounting the holder to the microtome. At least the grippable portion of the holder which is held by the microtome is formed of a compressible and/or deformable substance. Preferably, the holder is unitarily formed entirely of a compressible and/or deformable substance. The invention allows an object holder to be held more securely and to be molded economically.

  • Patent number: 5108080
    Abstract: An improved machine vise, particularly well suited for use on milling machines and the like, having an improved arrangement for securely holding workpieces of irregular shapes or several different, diversely sized workpieces simultaneously. The vise is provided with a fixed jaw and two movable jaws mounted in a side by side relationship such that each jaw is free to move back and forth into and out of a gripping relationship with the object being clamped. The two movable jaws are yoke driven on a shaft such that a single forward thrust of the yoke exerts a forward and downward pressure to move both jaws forward while at the same time allowing for a translational motion between said adjacent jaws. These jaws can thus simultaneously grip and secure individual workpieces of different dimensions or differently sized portions or cross-sections of the same workpiece. Each jaw may also be provided with individually mounted fingers that pivot into the best gripping relationship with the object being clamped.
