PETER MINEA, OF ST. PAUL, MINNESOTA.

SPECIFIGATION forming part of Letters Patent No.32l,995, dated July 14,1885.

Application filed March 3, 1886.

T0 aZZ whom it may concern.-

Be it known that I, PETER h/IINEA, a citizen of the United States, and a resident of St. Paul, in the county of Ramsey, and in the State of Minnesota, have invented certain new and useful Improvements in Vises, of which the following is a specification.

Figure 1 is a perspective view of the vise complete. Fig. 2 is a perspective front View, and Fig. 3 is a perspective rear view, of one of the removable jaws detached. Fig. 4 is a perspective front view, and Figs. 5 and 6 are perspective rear views,of one of the cheekplates, Fig. 4: showing the construction of the face of the plate, Fig. 5 showing the construction of the rear of the plate viewed from above, and Fig. 6 showing the construction of the plate viewed from below at the rear. Figs. 7, 8, and 9 are detached perspective views of the removable jaws, showing the various forms in which they will be constructed. Fig. 10is a sectional side view of the upper parts of the vise without the removable jaws.

A A are the two main jaws of the vise, having the usual screw, B, hand-lever B and parallel cross-bars O O, in the ordinary manner.

Attached to the inner face of the upper part of each of the jaws A A are metal cheek-plates D, with their upper parts projecting over their lower parts, as shown, leaving recesses or depressions a in each. A slot, 1), is formed through each cheek-plate, as shown in Figs. 4:, 5, and 6, and the faces of the slots within the depressed parts a are covered with curved hoods d, the slots and hoods thus forming sockets adapted to receive the tapering points 0 of the legs of auxiliary jaws or cheek-plate E.

By this means the auxiliary jaws may be inserted or removed at pleasure by merely lifting them upward.

The legs 6 are shown with offsets, so that the points e may be inserted into the sockets at the backs of the depressions a, and with the rears of the jaws E resting against the faces of the cheek-plates D, so that when the vise is in use the pressure will be borne by the bodies of the auxiliary jaws resting against the faces of the cheeks D, which in (No model.)

turn rest against the main jaws of the vise, so that the pressure will in no case be borne by the legs e or points 6.

The depressions a in the cheek-plates D are a very important feature of my invention, as they enable'nie to support the auxiliary jaws, with the hoods d, in lines back of the upper parts of the faces of the cheeks D, so that when the auxiliary jaws are removed no part of the cheek-plates projects beyond their upper parts, to enable the vise to be used as an ordinary vise when the auxiliary jaws are removed. This will be more clearly understood by reference to Fig. 10, which shows the vise with the auxiliary jaws removed.

Each of the jaws A A will be provided with one of the cheek-plates D, so that the auxiliary jaw may be attached. to either cheek; or, if required, two of the auxiliary jaws may be used, as shown in Figs. 7 and 8, which represent a concave jaw and a convex jaw adapted to hold curved pieces between them.

It is evident that any desired form of jaw may be used, and in practice I intend to furnish with each set of check-plates D a series of auxiliary jaws adapted to the varied forms of the work to be held.

In Figs. 1, 2, and 3 the auxiliary jaw E is formed with an angular back, and adapted to turn upon the leg e, so that the face of the jaw will adapt itself to the form of the work being held in the vise. This form ofjaw will hold with an equal pressure all angles within the radius of its movement.

In Fig. 9 an auxiliary jaw is shown, with the inclination at right angles to the inclination of the jaw shown in Figs. 1, 2, and 3.

This invention may be attached to nearly every form of vise; but it will generally be used on the wooden vises used by carpenters, wagon-makers, patternunakers, &c.

The invention may be applied to old vises, or attached to and sold with new vises, as pre ferred. 4
