1. A vice for gripping and holding an object comprising:
- a vice housing;
a vice jaw supported in said vice housing and being moveable in and out of said vice housing between an extended and a retracted position, said vice jaw being operable to grip an object;
biasing means for continuously urging said vice jaw toward the retracted position for clamping said vice jaw against an object;
a plurality of jaw teeth formed along one side of the vice jaw; and
at least one housing tooth formed in said vice housing for engaging said jaw teeth, said jaw teeth and said housing tooth being oriented to prevent movement of said jaw toward the extended position when said jaw teeth and said housing tooth are engaged so that said vice jaw may be pulled out of said vice housing only when the jaw teeth and the housing tooth are disengaged.

Abstract
The specification discloses a vice jaw 22 mounted in a vice housing 28. The jaw 22 includes a slidearm 44 for sliding within a slideway 46 in the vice housing. A plurality of jaw teeth are formed on the underside of the slidearm 44 and engage one or more housing teeth 50 to operate in a ratchet action. A spring 54 continuously urges the jaw 22 towards a closed or retracted position. When an object is placed in the jaw 22, the jaw teeth 48 and the housing teeth 50 are engaged and will prevent the jaw 22 from moving toward the extended position, but will allow the jaw 22 to move toward the retracted position.
