Abstract: A movable jaw quick release apparatus of a vice comprises a tooth base, a movable jaw and two restriction elements. The tooth base is formed with two inclined guide grooves, each of which has a first inclined surface, a second inclined surface and a bottom surface. The left and the right side surfaces of the movable jaw are formed with a through hole respectively. Each restriction element penetrates one of the through holes and moves between a first position and a second position along one of the inclined guide groove As the movable jaw generates vibration forces, each restriction element transfers the vibration forces to the tooth base, therefore, the movable jaw do not move upwardly and shake toward a work piece and reduce its clamping force for the work piece.

Abstract: The invention discloses an adjustable closure force control device for a screw-type vise and a method for selectively controlling the closure force of the vise. The control device uses a nut barrel for threadingly receiving a screw of a screw-type vise with a movable vise jaw being operatively connected to the screw so that advancement of the screw through the nut barrel results in vise jaw closure about an article to be held. The closure force control selectively controls the advancement of the screw through the nut barrel in response to the resistance to movement encountered by the movable vise jaw. In a preferred form of the invention, a compressible detent plunger cooperates with a series of apertures spaced about the nut barrel periphery. This allows the nut barrel to rotate with the screw, ending screw advancement and jaw closure despite continued screw rotation, when the predetermined resistance to jaw movement is encountered.

Abstract: An adjustable range vise is disclosed having a pair of clamping jaws, each of which is independently movable. Each jaw is carried by a respective horizontal slide. A first horizontal slide is received in a slot formed in one end of a fixed vise body, extending at least partially therethrough. A second horizontal slide is received in a mortise which is formed in a second opposite end of the vise body, extending at least partially therethrough. The mortise and the slot are positioned on separate substantially parallel planes, one above the other and on the same substantially vertical plane. The slides move horizontally, in opposite directions "overlapping" one another when needed. One of the jaws can be selectively adjustably secured, prior to clamping providing an adjustable clamping range or distance. This permits the size of the vise body to be reduced while still providing a sufficient clamping distance.
