Abstract: According to the present invention, a method and clamping apparatus for securely holding objects is disclosed. The clamping apparatus works in conjunction with hand tools used for holding objects such as a pair of locking pliers, micrometers, tweezers, tongs, etc. and can be attached to a workbench, table, or other stable surface. A preferred embodiment of the clamping apparatus has two main components: a base module which can be readily attached to a workbench, table, or similar stable surface; and a clamping module which is used to securely hold the hand tool. The two modules fit together by inserting several dowel pieces located on one module into corresponding holes located in the other module. The two separate modules are held together by frictional contact between the dowel pieces and the holes that occurs due to bending moments created when the base module is attached to a stable surface.

Abstract: Semiconductor wafer clamp device includes at least one clamp apparatus, the clamp apparatus including a removable clamp finger coupled to a connecting block by a connector. The device allows access to clamp apparatus from a top surface of a substrate holder, eliminating the need to remove the substrate holder in order to perform maintenance or repair operations on clamp apparatus. Tempered springs in the clamp apparatus reduce resilience losses experienced with non-tempered springs. Plastic clamp shaft bushings and spring retainers extend the useful life of clamp apparatus components by eliminating wear caused by metal-to-metal contact of moving parts.

Abstract: A vacuum-type clamping device for releasably holding a ski or other workpiece in a stationary position. The device is attached to a table by a C-clamp having the usual threaded rod. A suction cup is fixedly mounted on the non-clamping end of the rod and a nut carrying a rigid support ring having a pair of diametrically opposed contact portions is threadedly engaged with the rod. A surface of the workpiece is pressed into engagement with the upwardly facing, concave surface of the suction cup. The nut is then advanced on the threaded rod to bring the contact portions of the ring into engagement with the workpiece surface at positions on opposite sides of and spaced outwardly from the peripheral lip of the suction cup. Continued advance of the nut urges the workpiece away from the cup, thereby increasing the clamping force to the desired degree. The nut is rotated in the opposite direction to permit removal of the workpiece.

Abstract: A bow holder relates to a means of supporting a bow in a variety of positions in space while enabling the performance of work or other tasks to a bow and bow accessories. The archery manufacturers organization (AMO) industry standard of a threaded receptacle, usually a separate insert in the riser on the front of a bow, allows the bow holder to be attached to a bow thereby allowing the bow to be solidly supported in a vertical, horizontal, inverted, perpendicular or a combination of these positions relative to the work surface, as desired by the operator of the bow holder and the work to be performed. Use of the threaded receptacle to attach a bow to the bow holder is advantageous in that no contact is made with the painted surface or finished parts of a bow riser or lens.
