IMPROVEMENT IN VISES.

Specification forming part of Letters Patent No. 140,404, dated July 1, 1873; application filed

March 1,1873.

To all whom it may concern:

Be it known that I, Daniel S. Coe, of New Hartford, in the county of Litchfield and State of Connecticut, have invented a new and useful Improvement in Bench-Vise, of which the following is a specification:

Figure 1 is a side view of my improved vise, partly in section, to show the construction. Fig. 2 is a detail cross-section of the same taken through the line x x, Fig. 1.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish an improved bench-vise, which shall be so constructed that the movable jaw may move back and forth exactly parallel with the other or stationary jaw, and which shall be simple in construction, strong, and durable. The invention consists in the improvement of vises, as hereinafter described and claimed.

A represents the front or stationary jaw, the base of which is securely bolted to the bench. B is the inner or movable jaw, the lower end of which enters and moves back and forth in a groove, a', milled or otherwise formed in the upper side of the base of the jaw A, as shown in Figs. 1 and 2. Upon the inner side of the jaw A is formed a round bar, C, which is made hollow, and is slotted upon its lower side, as shown in Figs. 1 and 2. The bar 0 passes through and fits into a hole in the movable jaw B, so as to serve as a bearing for said jaw B to slide back and forth upon.

D is a screw, which is swiveled to the jaw A, and to its outer end is attached the lever by which it is turned. The screw D passes longitudinally through the cavity of the bar C, and through a nut, E_rformed upon the jaw B, and fitting into the cavity of the bar 0, the neck of said nut passing through the slot of the bar C, as shown iu Figs. 1 and 2. F is a screw having a left-screw thread formed upon it, and which is swiveled to the lower part of the stationary jaw A. The screw F is placed parallel with the screw D, and passes through a screw-hole in the lower part of the jaw B. The inner ends of the screws D F revolve in bearings in the yoke G, which also holds the said screws and the bar C in their proper relative positions. Upon the inner ends of the screws D F are secured small gear-wheels H, the teeth of which mesh into each other, so that by turning the right screw D the left screw F will be turned in the opposite direction, and the two screws will work together to carry the movable jaw B back and forth, exactly parallel with the stationary jaw A.
