ABSTRACT:
A quick change vice jaw plate arrangement includes jaw plates that may be rapidly secured to and rapidly removed from the opposing jaws of a vice. The jaws of the vice includes spaced jaw plate retainers which each carry a retaining pin. Each retaining is biased toward the face of the jaw and includes a relatively narrow shank and a relatively wider head. Each jaw plate has spaced retention recesses including a wide portion for receiving the head of the retaining pin, a detent portion for detaining the head of the retaining pin and a narrow portion for guiding it from the wide portion to the detent portion. A jaw plate may be quickly secured to a vice jaw by placing the wide portions of the retention recesses over the jaw plate retainers and sliding the jaw plate until the heads of the retainer pins seat in the detent portions of the retention recesses. The jaw plate may be rapidly removed from the vice jaw by a reverse action in which the heads of the retainer pins pop back up into the narrow portions of the retention recesses and exit through the wide portions of the retention recesses.
