UNITED STATES PATENT OFFICE.
ANSON P. STEPHENS, OF BROOKLYN, NEW YORK, ASSIGNOR TO A. P. AND
l M. STEPHENS & GO., OF SAME PLACE.
IMPROVEMENT IN VISES.
Specification forming part of Letters Patent No. 125,625, dated April 9, 1872.
To all whom 'it may concern:
Be it known that I, ANsoN l?. STEPEENs, of Brooklyn, in the county of Kings and State of New York, have invented an Improvement in Jaws for Vises; and the following is declared to be a correct description thereof:
This invention is designed for adapting machinistsvise to the holding of tapering and irregular-shaped articles. The ordinary vise is not adapted to holding tapering or irregular articles firmly because the jaws move parallel to each other. By my improvement the jaw can be moved so as to accommodate tapering and irregular articles, and, at the same time, the ordinary movement of the jaws will remain unchanged. My invention consists in a movable segmental jaw formed upon one side, with the ordinary roughened or other surface for clamping the article to be held, and at the other Y side, in the arc of a circle, coming in contact with a corresponding concave in the jaw of the vise; thereby the clampinglface will be moved into an angular or inclined position to the other jaw of the vise by giving to the said jaw more or less end movement in the said concave of the jaw.
1n the drawing, Figure 1 is a plan representing my improved jaw, and Fig. 2 is a vertical section of the sam'e.
a is the stationary jaw of the vise, and b is the moving jaw, `or vice versa; or the part b may be an auxiliary jaw attached to one of the jaws of the vise. In the jaw b is a segmental or concave recessed face or surface, against which the4 convex surface of the taper jaw c rests, the side 2 of said j aw c forming the clamping surface. An end movement given to this taper-jaw o will cause the face 2 to assume an inclination to the jaw a, and thereby accommodate the article to be clamped, and, at the same time, the parts will take a iirin bearing upon each other. The taper jaw c is supported by any suitable device. I prefer and use the ledge i and dovetail grooves and ribs; or suitably-shaped projections may be employed to connect the parts, but allow of the end movement of the jaw, as aforesaid.4 The angular rib 3, shown in the drawing, is effective for this purpose and easily constructed.
I do not claim a vise in which one or both jaws have movable faces hinged so as to swing on cylindrical segments or joints, as in Letters Patent No. 109,121.
I claim as my invention- The movable jaw c, made with one side straight and the other an arc of a circle, entering a corresponding recess, and sliding endwise therein, to vary the angle of the face of the jaw, as set forth. f
Signed by me this 7th day of November, A.
ANSON P. STEPHENS.
