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.
