COMBINATION WRENCH AND PLIEES.

Application filed July 2, 1921. Serial No.

concern:

Be it known that 1, JOHN B. SINonn, a

citizen of the United States, residing at Waynoka, in the county of Woods and State of Oklahoma, have invented certain new and useful Improvements in Combination Wrenches and Pliers, of which the following is a specification, reference being had to the accompanying drawings. This invention relates to that kind' of pliers or pipe tongs embodying a pair of crossing, lever-like handles having jaws, these handles being so pivoted together by means of a fulcrum pin or bolt working in a longitudinally extending slot that the jaws may be adjusted within the limits determined by the ength of the slot by sliding the handles edgewise with reference to each other.

The general object of this invention is the provision of a tool having opposed plier jaws at one end and alligator wrench jaws at the opposite end, these pliers being so adjustable that the jaws of the alligator wrench may be adjusted to suit objects of different sizes.

A further object is to so form the alligator jaws and handles aforesaid that the jaws are firmly supported when in an object-engaging position, and that no strain will be brought to bear on the bolt or pivot pin under these circumstances.

A further object is to form these alligator wrench jaws so that the confronting faces of the jaws gradually approach each other, thus ermitting a relatively large range of adjustments to be made.

Another object is to taper the jaws and set them at an angle to the handles so as to allow the alligator. jaws to be inserted in a very small place and yet retain their strength. 7

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein Figure 1 is a perspective view of my combination wrench;

Figure 2 is a top plan view of the wrench in one adjusted position;

Figure 3 is a top plan view of the wrench in another adjusted osition;

Figure 4 is a plan view showing the wrench in still another adjusted position;

Figure 5 is a section on the line 5-5 of Figure 2;

Referring to these drawings, it will be seen that my improved pliers or wrench consists of two members A and B. The member A is formed to provide a handle and a jaw 11 which is angularly extended with reference to the handle, the inner face of the jaw being cut away and toothed, as at 12, this jaw being formed adjacent its base with a wire receiving notch 13. The jaw is relatively thick at its outer end, as at 1 1, and the extremity of the handle 10 is curved, as at 15, and tapered, and the concave or inner face of this angularly bent portion toothed, as at 16, to constituate the jaw of an alligator wrench. This portion 15 is rel atively thicker than the handle 10 from the oint 17 to the extremity of the jaw, this aw portion 15 having a thickness equal to the thickened portion 14- on the extremity of the opposite jaw 11. Carried upon the handle 10 at its junction with the jaw 11 is a pivot pin 18 which is reduced and screwthreaded at one end, as at 19, and at the other end formed with a head. A nut 20 engages the screwthreaded, reduced portion 19 of this pivot pin or bolt.

The member B is provided with ahandle portion 21 which corresponds in length, thickness and width with the handle portion 10 of member A, and this handle 21 is widened, at 22, and formed with a longitudi nally extending slot 23 enlarged at its middle and at its ends to form sockets 24-, The extremity of the handle 21 is provided with a jaw 25 adapted to confront the jaw 11, the inner or concave face of this jaw being toothed, as at 26. The jaw 25 is thick relative to the handle 21, this thickened por tion of the jaw being defined by the shoulder 27, and just inward of the shoulder 27 the face of the jaw is cut away and formed with a cutting edge 28. This cutting edge shears across the notch 13. The opposite end of the handle 21 is angularly curved, as at 29, and its convex face is formed with ratchet teeth 30 which confront the ratchet teeth 16 of the portion 15. This jaw-like extremity of the handle portion 21 is also relatively thick, this thickened portion being defined by the shoulder31.

In assembling the parts, the two members A and B are disposed against each other so that the two relatively thick jaws 15 and 29 will be in alignment and all lie in the same plane, the pivot pin 18 then being passed through the slot 23 and through the member A and fastened by a nut. This pivot pin, as illustrated in F igure5, at its middle is formed with a relatively narrow shank l9 rounded at the ends. The slot 23 has a width the width of the pin 19 and this pin is disposed at such an angle with relation to the longitudinal axis of the handle 10 that the handle must be shitted to an angle of about 45 with the handle portion in order that the section B can be longitudinally shifted upon the section A.

' course, when the pin 19 is in any one of the sockets 24, the handle members can be oscillated with relation. to each other, but when the handle members are closed, as in the clamping position of the tool, it is impossible to shift the sections A and B longitudinally with relation to each other.

By shifting the sect-ions A and B with relation to each other, the jaws 11 and 25 may be adjusted to engage work of various sizes, but the particular construction of the aws 11 and 25'forms no part of my invention, my invention residing in the combination with the jaws 11 and 25 of the jaws l6 and 29 and in the particular shape and relation of the jaws 16 and 29. It willbe seen that the jaws 16 and 19 are tapered so that they may be readily inserted in relatively small spacesand that the ing toothed faces 16 and 30 are divergently related to each other so that by longitudinally adjusting the members A and B with relation to each other, a large range of apalication of the wrench or pliers is secured. )y forming the jaws l5and 29 of the full thicknes of the tool, that is forming. these jaws with the shoulders17 and 31, it will be obvious that strain placed upon these jaws will be transmitted to the shoulders and this strain will not be transmitted to the pivot pin or bolt 19. The handles 10 and 21. have the same width and are flat upon their confronting faces and rounded upon their outer lares so that the jaws, when closed or nearly closed, provide for a good grip.

The combination alligator wrench and plierwhich I have devised is extremely convenient, particularly for automobilists, and

the combined wrench is adaptable for a large variety of confront.

purposes. It is obvious that the design of changed in details without departing from the wrench may be 7 the spirit of the invention as defined in the the cont'rontingl'aces of the .jaws being toothed and having divergent relation to eachother and each jaw being tapered toward itsextremity. V

2. A wrench of the character described comprising two confronting bers, each formed atone extremity with an outwardly curved jaw, the jaws confronting each other, the end of each member remote from said first named. jaws being angularly bent, the angularendsof the members extending in the same direction, each angular bent portion having a thickness equal to the thickness of both handle memhandle memhers whereby the last nam'ed jaws aredis- V posed in the same jaws on their confronting faces being toothed, said toothed faces having an outwardly divergent relation to each other, one of said handle members being longitudinally slotted, the slot being enlarged'to form a series of sockets along thelength of the slot, and a fulcrum pin attached to the face of the other handle member tending through the slot and having. a diameter in one direction equal to the width:

of the slot and in a transverse direction greater than the width of the slot but less than the diameter of the sockets formed along the slots and the pin being disposed at alougitudinal axis to the'handle upon which it is mounted whereby said members can be turned into angular relation to each other to permitone of the members being longitudinally shifted upon the other member.
