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.
A dovetail positioning device including a fixed base member with teeth in at least one angular dovetail surface a moveable member with dovetail cross section of shape and size to interfit with the fixed base a clamping means to force the teeth of the fixed and moveable members to mesh thus establishing a repeatable position in three planes.
A jaw plate with parallel and opposing flat surfaces one surface having a specially machined detail that when mated with matching adapters hold said jaw plate by spring tension against a flat surface while urging said jaw plate against a stationary hard stop on said adapter while simultaneously urging said jaw plate against the floor of a gripping device such as a machine vise.
