Abstract

A vise jaw assembly can be easily mounted on, and removed from, the jaws of a machine vise. A first reusable component bolts onto the face of a machine vise jaw. A second component is inexpensive and disposable. It is made by extrusion of an easily machinable material such as aluminum. It has a flat face that is designed to engage a flat face of the first component. It has an element extending from the flat face such as a dovetail element that slides laterally into a correspondingly shaped recess in the first component to complete a dovetail type joint. A slot below the recess in the first component is compressed by threaded fasteners to tighten the joint. The second component has a uniform cross section so that it may be produced by extrusion with minimal finishing except for cutting to length.

Dependent claims

A vise jaw plate assembly for mounting on a face of a vise jaw of a vise that is adapted for translatory motion in a first direction, the assembly comprising:

a) a first component having:
i) a top, a front face, and a rear face;
ii) a plurality of first apertures extending in the first direction between the front and rear faces, the apertures constructed for receiving jaw-engaging first fasteners with their fastener heads being recessed below the front face when the rear face is held against the face of the jaw by the first fasteners when received in threaded holes in the jaw face;
iii) a dovetail recess in the top, the recess having opposed side walls and a bottom portion, the recess extending the full width of the first component in a direction transverse to the first direction;
and
iv) a slot extending downward from the bottom portion, the slot extending the full width of the recess;
b) a second component constructed of a readily machinable, material, the second component having a uniform cross section for formation by an extrusion process, and having:
i) a first face;
and
ii) a dovetail connector element projecting from the first face, the connector element extending along the full width of the face, the connector element constructed to mate securely with the dovetail recess in the first component while the first face is in close contact with the top of the first component;
and
c) a plurality of second apertures extending in the first direction between the front and rear faces of the first component, the second apertures having a first unthreaded portion between the front face and the slot and a second, threaded portion between the slot and the rear face, the second apertures constructed for receiving therein second fasteners for threadedly engaging the second, threaded portion with fastener heads being recessed below the front face to thereby contract the slot, and securely hold the dovetail element of the second component within the recess.
