BENCH-VISE.

SPECIFICATION forming part of Letters Patent No. 572,367, dated December 1, 1896.

Application filed October 23, 1895. Serial No. 566,651 (No model.)

To otZZ whom, it may concern:

Be it known that we, JOHN F. PARKER and CALVIN M. BENNETT, citizens of the United States of America, residing at Portland, in the county of Cumberland and State of Maine, have invented certain new and useful Improvements in Bench-Vises; and we do hereby 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 appertains to make and use the same.

Our invention relates to improvements in bench-Vises, and especially to that class of Vises having two movable jaws, one of which is capable of being swiveled, so as to fit any desired bevel on the work to be inserted between the jaws.

It consists in a novel way of attaching the vise to the bench so that it may be swung in any desired position of means for raising and lowering the same so that it may be higher or lower than the bench, as desired; novel means for locking the vise when it is in the desired position, and also in novel means of attaching, adj ustin g, and moving the clamping-jaws, and in certain other details of construction, which will be hereinafter more fully set forth and specifically claimed."

In the drawings herewith accompanying and forming a part of this application, Figure 1 is a vertical section of our improved device. Fig. 2 is an end elevation of the same. Fig. 3 is a top plan view of the same, dotted lines showing the adjustability of the clampingfaces. Figs. 4, 5, 6, 7, and 8 are detailviews of the differentparts used in the construction of the vise; and Fig. 9 is a perspective view with a part of the bed of the vise broken away, showing means used for holding the vise away from or close to the bench.

Same letters refer to like parts.

In said drawings, A represents a suitable bench, to which is pivotally attached, by a single or double yoke B, bracket 0, which sustains the bed of the vise. Adapted to extend through sockets D in the yoke is a rod E, threaded, as at F, and having on its lower extremity a suitable handle or wheel G. Said rod E also extends through the sustainingbrackets of the vise, the lower extremity of which is provided with a threaded socket, so that when the handle is turned one way or the other by the thread in the socket in the bracket engaging the thread on the rod E the vise-bracket is raised and lowered as desired. Adapted also to fit into sockets H in the yoke and vise-bracket is a rod I, having pivoted on its lower extremity a lever J, provided with a cam-surface K, by which, when the lever is brought into action and the cam-surface is forced against the bottom of the vise-bracket and yoke, the vise is held firmly, thereby preventing it from moving on the rod 1.

Attached to the yoke B, as described, is a box L, which constitutes the bed of the vise. Said box is hollowed out and provided With a guide M to keep the rod N in position. Said rod N is provided on a portion of its circumference with ratchet-teeth O. Pivotally attached to the bed of the vise by means of an ear P is a pawl Q, adapted to engage the ratchet-teeth on the portion of the circumference on the rod N. The outer extremity of said rod N is provided with threads R. Said rod N is also provided with astop S, as shown in Fig. 4. Attached to said rod at its threaded portion by means of the nut and screw T is a clamping-jaw U, which constitutes the outer clamping-jaw of the vise.

Pivotally attached to the plate V by means of the pin W is the other clamping-face X of the vise. In'order to prevent this jaw from displacement when pressure is brought upon it, we provide the bed of the vise with sockets to and a pin Z), which is inserted through the clamping-jaw and the plate upon which it is mounted into sockets a. In order to adjust the clamping-jaw X at an angle requisite to receive the work, the pin 1) is removed from its socket c in the clamping-jaw and the jaw X is then adjusted at the proper angle, the pin 1) being insertedbehind the plate, as shown at d in dotted lines in Fig. 1. In order to move the outer jaw U, the workman has only to turn the pivoted handle 6 a sufficient distance so as to throw the ratchet-teeth 0 out of engagement with the pawl Qthat is, until the stop S bears against the confining-Wall of the vise-bed. Then the rod N may be pulled out or pushed in, as desired, and the handle turned so that the pawl may once more engage the ratchet-teeth. Then turn the handle 6 so as to tighten the thread. By this means the clamping-jaw is moved slightly 'cles, and the vise isready for use.

a rod g, adapted to slide in the socket h in the ear i, attached to the bed of the bench. Iivotally attached to said ear 2' is a leverj, having a cam-surface Kthereon. It will be seen that when the cam-lever j is pressed down it will force the rod g against one of the edges in the ear i and hold it firmly in position, and that when the lever is loosened and the pressure removed from the rod gthe vise may-bemoved toward'or away'from the bench, the rod 9 being allowed to slide in the socket 7b in "the ear 1'. Then the vise has been adjusted at a properdistance from the bench, the lever j is tightened and then'the rodg is forced against the upper edge inthe socket h, by means of which the bed of the vise is firmly held in position and prevented from moving-away from'or toward the bench.

The operation of our improved vise is as follows: When the workman wishes to insert any article between the clamping-jaws, especially'if the end of the article is'cut on any size and length of the articles require, inserts the pm I), as shown in dotted lines at (Z in 'Fig. 1, then forces the rod and clamping-jaw U inwardly until the clamping-jaw bears against the outer extremity of the work, turns the handle 6 so that the ratchet-teeth canbe brought into engagement with the pawl, then turns the handle sufficiently to bring the clamping-s urfaces firmly up against the arti- Should the work be of'such a kind as to require the vise to be raised or lowered more than is ordinarily needed, the workman has only to turnthe handle G on the rod E. This, owing 'tothe threads on the rod engaging the threads in the socket of the vise-brackets, will enable thevise to be raised and lowered as the workman desires. approach the work from a different side in- Should the workman desire to ever way he wishes it, the vise moving 011 the yokes B. The levers arethen placed in position and the vise is 'rigidly'held in position.

WVe do not wish to limit ourselves to the specific form described for attachingour vise to the bench or for holding it away from or close to the bench. WVell-known mechanical equivalents can be used for accomplishing the same result without materially altering or "changing the invention.

Having thus described our invention and its use, we claim-- 1. In a bench-vise the combination of two clamping-jaws one of which being adjustable at any an gle,'means for holding said clampingjaws in position, means for pivotally attaching the same to a rigid object, means for raisin g and lowering the vise, means for swinging the vise and holding it in any desired position, substantially as and for the purposes set forth.

2. In a bench-vise the combination of a bed provided with sockets therein of two movable clamping-faces the one adapted to slide on said bed and adaptedto beset at any'angle the other mounted'upon a rod threaded part way of its length and'havin g on a portion of its circumference ratchet-teeth adapted to engage a pawl pivotally attached to "the bed of the vise, meansfor throwing said ratchetteeth and pawl out of engagement and means for moving said clamping-faces, substantially as and for the purposes set forth.

3. In a bench-vise in combination a bed two adjustable clamping-jaws one or more yokes pivotally attached to the vise and rigid object, a rod extending from the rear of the bed through a slotted plate attached to the rigid object, a cam-lever-attached to said slotted plate and adapted to hold said rod rigidly in place, and means for raising and lowering the bed, substantially as and for the purposes set forth.

4. In a bench-vise in combination,'a suitable bed providedwith sockets, two adjustable clamping-faces moving on said bed, said bed being pivotally connected by means of a bracket and yoke'to a suitable rigid object,

an ear attached to the rigid object and having a slot therein, a rod pivotally attached to the bed of the vise and adapted to slide in the slot in said ear, and means for holding said rod rigidly in position, substantially as and for the purposes set forth.

5. In a vise the combination of. a bed pivotally attached by means of yokes to a-bench and adjustable clamping-surfaces adapted to move on said bed one of the clamping-surfaces adjustableby means of a rod threaded part way of its length the unthreaded portion being provided with ratchet-teeth on a part of its circumference, a pivoted pawl attached to said bed and adapted .to engage the ratchetteeth when in position, means for throwing said pawl and ratchet-teeth out of engagement, means for moving tlieclamping-jaws and holding the same in position, means for swinging the vise away from or toward the bench, means for looking it in any desired position, substantially as and for the purposes set'forth.
