ADJUSTABLE VISE WRENCH.

Application filed December 19, 1923. Serial No. 681,620.

To all 107mm, t 11m-y concern:

Be it known that I, Anfrirun B. FAUnKNnR, a citizen of the United States, residing at Williamsport, in the county of Lycoming and State of Pennsylvania, have invented certain `new and useful improvements in Adjustable Vise Vllrenches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the artto which it appertains to make and use the same.

This invention. relates to wrenches of the type generally known as adjustable wrenches.

ltis well known that in using such wrenches as heretofore ordinarily constructed the jaws are liable to slip and become disengaged from a nut or other article clamped between the jaws by the usual clamping means, thus causing much trouble and annoyance in accomplishing the desire-d result.

The objects of my invention are to o-v-ercome these objections and provide a simple, efficient and durable wrench having in addition to the means ordinarily employed for adjusting the k movable jaw so as to bring the aws together and clamp a. nut or other article between the jaws, simple, efficient and reliable means acting independently of the usual adjusting means so as to easily and quickly tighten the grip of the aws upon the nut or other article and prevent the jaws from slipping off or becoming disengaged until released by said gripping means.

A further object is to provide a wrench of the character referred to with clamping means operable with one hand and adapted to exert a powerful force with little expenditure of energy in order to fasten the grip of the jaws upon a nut or other article, and to adapt the clamping means to easily and quickly automatically release the grip yof the jaws and permit the. removal of the wrench without the annoyance and trouble that is often experienced in using ordinary adjustable wrenches.

The invention will first be hereinafter more particularly described, with reference to the accompanying drawings, which are to be taken as a part of this specification, and then pointed outl in the claims at the end of the description.

ln said drawings, Fig. 1 is a side view of is an edge or back view of the F ig. 6 is a detail sectional view taken on the line 2-2 of Fig. 4, looking in the direction of the arrows, and

Fig. 7 is a fragmentary detail view showing jaws having their confronting surfaces serrated or provided with line teeth, similar' to a Stillson wrench, vfor use as a pipe wrench.

Referring to said drawings, in which the same reference characters are used to denote corresponding parts in different views, the letters A and Asl denote the jaws of an ordinary adjustable wrench, the aw A1 being slidably secured on the shank a of the relatively fixed jaw A, and B denotes the usual adjusting device or screw for bringing the jaws together, said screw being provided with an enlarged peripherally roughened head b for turning it t adjust the movable aw in the usual way. The shank a has rigidly secured thereto, as shown in Figs. 1 and 2, or formed integrally therewith, as shown in Fig. 5, a handle member C which is preferably substantially semicircular or trough-shaped in form and pro-- vided on the inner side thereof with an apertured or bifurcated lug or projection c, near the base of the handle or its junction with the shank, to form an abutment for one end of a spring D, the other end of which abuts against a nut (Z screwed on the free end of a rod Z1 carrying the spring; said rod passing through the lug c so as to adapt the spring toexert a force tending to pull the rod toward said lug. The rod Z1 is pivoted at its inner end to a rod or bar' Fi, which is preferably U-shaped or in the form of a yoke-the arms of which embrace a crosspiece F, and are ,secured at their free ends CTI to a` bearing member' G slidably mounted in an opening through the inner end or base of the rigid handle member C and having a socket therein to receive a pintle or stud g en the rear end of the screw B, so as to provide a bearing for the screw at that end, the other end of the screw being inserted in an interiorly threaded socket in the part el of the movable jaw as usual in adjustable wrenches. One end of the erosspi-ece F is inserted in a slot or hole in the handle member C, so as to provide a fulerum on which it may rock or tilt; the other end f1 thereof being arranged to engage a shoulder formed in a recessed end portion of an auxiliary handle member C1, which is pivotally mounted beside the handle member C and may be solid, though preferably trough-like in form, for lightness.

The cross-piece F is preferably recessed between its two arms to provide a seat for the pointed end of the bearing member Gr on which it may roel; or tilt in a forward direction under pressure of the auxiliary handle member' or the recoil of the spring which tends to hold the cross-piece in the position shown in Fig. 5 and through it held the auxiliary handle member normally in the inclined position also vshown in Fig. 5. rl`he head b of the screw B is held in a relatively fixed position, to prevent movement thereof in the direction of the axis of the screw, while permitting free rotary movement, by means of a slidable bracket Il having its end bent toward the screw so as to straddle the head t) with one end fitting in a groove in the bearing member G and the other end overlapping the head and resting upon a ila-nge or shouldered portion thereof so that longitudinal movement ofthe screw independently of the brac-liet is prevented while rotary movement thereof is permitted, for adjusting the movable jaw forward and bac-l; along the shank of the fixed jaw A.

In the modification shown in Fig. 3, which is designed for a. small wrench with thin jaws, a rack-bar l is used to take the place of the adjusting screw shown in Figs. l and 5, and the bearing member shown in the last mentioned figures is omitted and in place thereof the rear end'of the rack is formed with an enlarged. and pointed end which seats against the tilting cross-piece in the manner and for the purpose described with reference to Figs. l' and 5. ln said modi tication the movable jaw is adjusted forward and back by means of a worm gear K which travels therewith, said gear being revolubly mounted in a socket formed in the base portion of the movable jaw, and a slight forward and back movement of the movable jaw independently of the Aworm gear and rack adjustment for tightening the grip of the jaws on a nut-or other article held between .the jaws, is accomplished by pressing the auxiliary handle member toward the rigid handle member in the manner hereinbefore described.

n Fig. 7 jaws are shown having tine teeth or serrations on their working faces to adapt the device for use as a pipe wrench.

The utility and advantages of my improvement over wrenches as heretofore ordinarily constructed are obvious. The eoacting pivoted handle member and associated parts provide 'a compound lever movement by which the user is enabled with one hand to easily and quickly tighten the grip of the jaws on a nut or other article, after it has been clamped between the jaws by manipulating the ordinary adjusting devicesy with the other hand, and with such power that it becomespractically impossible for the jaws to release their hold until the gripping device is released, this being accomplished quickly and automatically by the recoil of the spring, which retracts the movable jaw and simultaneously restores the lever member of the handle to normal position the instant the pressure thereon is removed.

In the form shown the slot or hole in the handle member C, in which one end of the cross-piece or lever F is inserted and has its fulcrum or bearing at that end, is directly opposite a shoulder c1 on the other handle member Cl, on which thel free end of said cross-piece has a bearing, and the bottom of the recess Vin said cross-piece forming a seat forthe pointed end of the sliding 'bearing member G, at the opposite side of said bearing points, is arranged directly in line with the two bearing points first mentioned, or in otherwords, there are two points of bearing on the back of saidcross-piece and an intermediate one on the front, all arranged directly in the same line, which arrangement is preferred, as it prevents any sliding motion. l I

It will be understood of course that various changes may be made in the details of construction and arrangement of parts without departing from the spirit. and scope of my invention. y

Having thus described my invention, what I Claim as new and desire to secure by Letters-Patent of the United States is l. An adjustable vise wrench cou/iprising in combination with an ordinary wrench having jaws and associated adjusting devices for bringing said jaws together, means for tightening the grip of the jaws consisting of a main handle member rigid with the shank of the wrench and an auxiliary handle member pivoted at one end beside andat an angle to said main handle member, and spring-actuated means and connections between the same and said adjusting devices tending to separate the jaws, said springactuated means and connections being arranged in the line of the longitudinal axis lOtl llt)
