IMPROVEMENT IN CARPENTERS VISES.

Specification forming part of Letters Patent No. 57,250, dated August 14, 1866.

To all whom it may concern:

Be it known that I, ORLANDO V. FLORA, of Madison, in the county of Jefferson and State of Indiana, have invented an Improved Vise; and I do hereby declare that the following is afull and exact description thereof, reference being had to the accompanying drawings, making part of this specification- Figure l being a side elevation of a wood or carpenters vise as improved by me; Fig. 2, a rear view thereof, the bench being shown in vertical section; Fig. 3, a view representing the invention as modified for an iron vise.

Like letters designate corresponding parts in all of the figures.

Let A represent a carpenters bench, B the stationary jaw ot the vise attached to the bench, and G the movable jaw of the vise. The beam D has out, for a I'ew inches on its rear end, a screw'thread, n, which turns in a nut, F, simply for tightening the jaws against the article to he clamped. The principal movement of the movable jaw C-in and outis effected simply by sliding backward and forward the beam D, moving freely through the stationary jaw.

In order to keep the beam in its proper horizontal position the nut F has two side projections, ff, which slide in ways acl'of the bench, as shown in Fig. 2.

A brace, I, extends from near the lower end of the movable jaw O, where'it is attached thereto, backward and upward through a vertical slot in` the stationary jaw to the nut F, or to a block, t', attached thereto, being pivoted or otherwise secured to said block or nut, as at m, Fig. l. This keeps the movablejaw always in a position parallel, or nearly so,with the stationary jaw.

My present improvement consists in the employment of a ratch-bar, G, under the beam, secured to the nut F at the rear end, while its front end enters and slides in the movable jaw U. The teeth g g ot' this ratch hold upon a txed catch, H, firmly attached to the stationary jaw B, substantially as represented, and

thus the movable jaw is held from moving away farther from the stationary jaw, in whatever position the rateh may be placed.

ln order to slide the beam and movable jaw in or out the outer end ot' the'beam is simply rst raised (the beam-aperture through the stationary jaw heilig enlarged vertically enough for the purpose) till the ratch-teeth are disengaged from the catch, and then the beam can be directly moved in or out to any extent without hindrance. Then, when the outer end of theI beam is dropped, the ratch Gr hooks on the catch H again, and holds the movable jaw to that position. When the jaw is by this means brought up to an article to be clamped a turn or two of the beam causes the screw n to tighten the jaw firmly against the article.

To unclamp, the screw is first reversed till the article is loosened, and then the beam is free to be moved in orout, as above described.

Fig. 3 shows the vise as modified for ironwork. Here the stationary jaw B has a snit able dan ge, P, to secure it upon the top of the bench by screws t, and thereis a slot,R, therein, in which a guide-pim. S, with a head, fr, slides to keep the ratch G in place. In this case the beam does not extend back over the ratch, but the ratcb-bar forms the beam proper, and its frontend bends upward to form a nut, F, the movable jaw U being pivoted to it, as at g. There is then a mere tightening-screw, D, where the beam would be in the wood vise. No brace to preserve the parallelism is here needed.

What I claim as my invention, and desire to secure by Letters Patent, is-

The combination of the fixed catch H and the ratch-bar G, movable up and down to clear and engage with the catch, substantially as and for the Apurpose herein specified.

The above specication of my improved vise signed by me this lst day of June, 1866.

ORLANDO V. FLORA.
