BENCH-VISE.

SPECIFICATION forming part of Letters Patent No. 288,549, dated November 13, 1883. Application filed August 23, 1883. (No model.) i

To all whom, it may concern:

Be it known that I, WILLIAM H. CLOUD, of

State of Michigan, have invented anew and useful Improvement in Bench-Vises; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, referencebeing had to the accompanying drawings, which form a part of this specification. I

My invention consists in the combination of devices and appliances hereinafter mentioned, and more particularly pointed out inthe claims.

In the drawings, Figure 1 is a front elevation of a device embodying my invention; Fig. 2 is a vertical section, showing parts in elevation. Fig. 3 is a rear elevation of the same.

A represents a bench.

B is the jaw of my bench-vise.

O is a bar at its base, which may be provided with the usual holes and pins for setting it in any position; or any automatic means may be provided for this purpose, this forming no par ticular partof my invention;

D is a shaft. It is provided with a screwshank upon its outer end, at (Z, which passes loosely through a metallic collar, b, on the visethe shaft in this position,

jaw. Upon the screw-shank is a hand-wheel, D, or cross-bar, adapted to run upon the screwshank and bear against the metal collar, thereby tightening the jaw upon any interposed obj ect. Theshaft Dis also provided with notches E, which engage a latch, F. This latch may be thrown into or out of gear with the notches by means of a cord, f, at the will of the operator. The notches E are beveled upon one side, so as to permit the shaft D to'be pushed in and so ride under the latch.

The operation of the device is as follows: When it is desired to insert a piece of timber or other object in the vise, the operator draws on the'cord, and thus lifts the latchout of the notches E. He can then pull out the shaft D as far as need be. He then inserts the object in the jaws and shoves the shaft forward until the jaw rests against the object. The latch F holds and the operator, by turning the hand wheel or bar, forces the jaw firmly home against the interposed object.

secured thereto, the movable jaw,

I Instead of using the cord for lifting the latch,

there may be employed a crank-lever j ournaled in the bench A, so that one arm thereof will bear against the under side of the latch and the handle G thereofwill project outside of the bench, so that when the handle is turned in one direction the latch will be raised, and when turned in the opposite direction the latch may fall by gravity. I

The plate I-I, through which the shaft passes, is formed with a sleeve, H, aportion of which enters the side of the bench, as shown in Fig. 2, and is preferably secured by ribs I, projecting therefrom so as to enter the bench, as well as by screws or bolts.

Of course, if the jaw is of metal, the metallic collar 12 may be dispensed with. So, also, instead of locating the latch to drop by gravity into the notches, it might be located'so as to be forced. into the notches by a spring, and be thrown out in like manner by the cord or lever, as described.

What I claim is 1. The combination of the bench, the sleeve the notched shaft passing through the sleeve and having. a screw-threaded outer end passing through an opening in the jaw, the wheel or bar. adjustable on the threaded end of the shaft to bear against the jaw, a latch having one end pivoted to the inner side of the bench and extending across the notched shaft, and a deviceconnected with the latch and extending through the bench for lifting the latch to disengage the latchysubstantially as described.

2. The combination of the bench, the plate provided with the sleeve and ribs entering the bench, the movable jaw, the shaft passing through the sleeve and jaw, and having one portion screw-threaded and the other portion notched, the latch pivoted within the bench,

" a device connected with the latch and extending through the bench for raising the latch from the outside, and the wheel'or bar on the threaded end of the shaft, substantially as de scribed.

3. The combination of the bench, the plate provided with the sleeve and ribs entering the bench, the movable jaw, the shaft passing through the sleeve and jaw, and having one I GO portion screw-threaded and the upper face of the other portion notched, the latch pivoted tion in the presence of two witnesses.
