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.
