Specification of Letters Patent.

Patented Apr. 20, 1915.

Application filed May 23, 1914. Serial No. 840,400.

To all whom it may concern:

Be it known that I, JOHN R. LONG, citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Bench-Vises, of which the following is a specification.

This invention has reference to improvements in bench vises, all substantially as shown and described and particularly pointed out in the claims.

In the accompanying drawings Figure 1 is a plan view of the vise and Fig. 2 1s a SE16 elevation on a base. Fig. 3, Sheet 2, 1s a longitudinal sectional elevation, Fig. 4: 1s an outer end elevation and Fig. 5 a cross section through the yoke and other parts on line 5-5, Fig. 3. Fig. 6 is a detail of the wrench or handle.

The one material and distinguishing difference in the present invention over that shown in my application Serial No. 747,214 is the straight central bar B, as compared with the tapered bar in the said application. This improvement was found to be necessary to get a sufficient working latitude for the inner or sliding jaw member 2 as compared with the fixed jaw member 3. Furthermore, with the present improvement the yoke 4 looks the free jaw as tightly and firmly when moved to its farthest limit or wide open as when near to it, which was impossible under the former construction. For example, by reference to the said bar in the former application it will be seen to have a straight top edge and an inclined bottom edge, making the bar gradually wider or deeper on its sides toward its rear end. This necessarily pulled the yoke down in corresponding measure as the parts were moved away from the fixed jaw and at last, at the limit of open movement between the jaws, the yoke would engage over only the re duced extremity of the movable jaw, or jaw shank. Obviously, the grip or hold of the yoke on said jaw would be materially less and weaker over the point or end of its tapered shank than over the body thereof as shown herein, and which by the use of a central supporting bar with parallel top and bottom edges, as in this case, is the invariable working or gripping position of the yoke on said jaw 4 however far it may be open. Indeed, the said bar may be extended to any length over and above that shown and the jaw 2 and yoke a will sustain exactly the same working or looking relation however far removed from jaw 3. Now, incident to this fundamental and important diiference over my former application, there are certain details which cooperate with this improvement to make it effective, as the roughened or serrated lower edge a of bar B and the keeper 6 roughened or serrated on its inner edge to engage the serrations a and having a greater length than the yoke and confined in the bottom thereof by heads or flanges f on its ends. This keeper or piece 6 is essentially the locking member for the yoke and inner jaw 2, because when the jaws are engaged upon an object the said member or keeper 6 secures them against possible release until released or loosened purposely. The said keeper is longer than the yoke so as to be more or less slidable therein as well as provided for sliding the yoke more or less as to the keeper and tightening of the jaws upon an object is effected through the bar B after the inner jaw and yoke have been placed in the closest possible position to the object to engage the same in the jaws by drawing the bar lengthwise by means of the threaded thimble or nut 7. The said thimble is engaged on the threaded end of said bar next outside the permanent jaw shank or base and bears against the said base as its backing. A wrench or handle it is adapted to engage upon and turn said thimble or sleeve 7, and this draws the yoke in tightening relations on the jaw 2 while it also looks the yoke through the keeper 6 on bar 13. The said bar, B, is pivotally and slidably mounted at its outer end between ears 10 on the extremity of the body of the jaw 3, and has a slot through which it is engaged on a pivot bolt 9. A. thrust bolt 12 depends from the end of said jaw body beneath its pivotand has a head engaged by a spring 12 therein to normally hold the said bolt in raised position. A locking plate or device 15 is adapted to rock on screw 16 depending from the said body next within said bolt 12 and is adapted to be depressed by the said bolt on its outer end while its inner end locks frictionally beneath a lip 18 011 the base 6. This makes screw 16 both a support and a pivot for the said plate or look 15, so that when the jaws are tightened upon each other or upon an object in the vise the back or down pressure on the extremity of bar B will depress bolt 12 and tighten the plate 15 on the lip 18, and thus prevent rotation of the vise while the same is locked for work.

Otherwise, when the parts are liberated the 7 shank or jaw. The jaw member has a horizontally disposed body which terminates in the upwardly projecting ears 10. between which bar B is engaged, and the other end of said bar with its screw threaded extremity 11 passes through the base or shank of the jaw proper, which is also referred to herein as the outer jaw. The top'edge 5 of the said jaw body is parallel with the bar B, and in such proximity to the lower edge of said bar that the yoke A can rest thereon when not closely engaged over the inner jaw or when a shift of parts is made.

A threaded sleeve or thimble 7 which draws the bar B has a flange or collar 0 about its inner end engaged beneatha lip n on the back of jaw 3 to confine the sleeve in working position, and said sleeve is rounded in advance of said lip but its end is of octagonal shape to correspond with and fit the open end of the wrench 2. By merely slipping the wrench backward out of engagement with the octagonal end 2 of the nut or sleeve 7 it will befree to rotate independently of the sleeve and to drop by gravity to a hanging position. A pin 11 prevents the wrench from coming OE and limits the outward movement thereof on the octagonal end.

The yoke 1 is provided with side'handles 8 to move it back and forth relatively to the tapered body of jaw 2 and bar B, and when the yoke is moved back against the stop pin 24 it will ride down the inclined surface of the jaw body and come to a rest on the top edge 5 of the body of jaw 2. This frees the keeper which drops by gravity and any further backward movementimparted to the yoke will slide the jaw 52 rearwardly by contact of the yoke with pin 24.. The movement of the yoke upon the movable jaw is slight and may be'limited to one-fourth of s an inch, more or less, but the movement of the jaw 2 relatively to fixed jaw 3 is only limited by the length of the bar B. When the yoke is moved forward the keeper is not immediately lifted into engagement with the teeth a on the bar B as the weight of the yoke or a slight downward pressure by hand while sliding the yoke and jaw forward will prevent this action from occurring.v However, when the jaws come together against each other or the objector work to be held, the yoke will ride up the inclined or tapered body of jaw 2 and bring thekeeper into locked relations with the serrated or toothed edge a of bar B. Rotation of the nut or screw sleeve 7 by handle it may then take place to carry the movable jawforward to tighten and grip the work between the jaws. 7 j 7 What I claim is: i V j v 1. A bench vise'as described having an outer jaw with a body having an upturned outer end, in combination with abar sup-x ported in the base of said jaw and in said outer end, an inner jawj'and a yoke con+ fining the same slidable on said bar, a sepa-j ratelocking piece in said yokeadapted to lock on the lower edge of said bar and means to draw said bar lengthwise in its supports and lock said yoke thereoni n 2. A bench vise as described havingan outer jaw with a horizontally disposed body and an upward projection at its rear end, a 7 bar having parallel upper and lower edges supported iii said projection and in the'base of said jaw, an inner jaw having a substantially wedge shaped shank slidable on said bar and a yoke engaged over said shank and bar, the said bar having serrations on its bottom, a separate locking piece. confined in said yoke and slidable therein provided with teeth engaging said serrations and means to draw said bar into tightening relations r with said yoke and locking piece.

3. A bench vise as described, having out/er jaw with a horizontally disposed body and a bar slidably mounted on said body having a roughened lower. edge in combinaloo tion with an inner aw and a yoke over the T same andsaid bar, a separate locking piece of greater length than 'the width of said yoke supported in the bottom of the yoke Y 'and having confining heads at itsiends and teeth to engage said roughened "edge, and

rotatably mounted on its pivot, a thrust bolt inthe outer end of said'jaw. body engaged by the end of said bar and means engaged by the said bolt in looking relations with the said base and adapted to prevent rotation'of locked position.

5. A bench vise of the kind described the vise on the base when the vise is in i comprising inner and outer jaw members;

slidably'related andv a bar mounted at its ends on said outer jaw member and having a plaln upper edge and a roughened lower edge parallel therewith, in combination with In testimony whereof I afiix my signature a yoke slidably mounted over said inner in presence of two Witnesses.
