SPECIFICATION forming part of Letters Patent No. 625,145, dated May 16., 1899.

Application filed February 20,1899. fierial No. 706,210. (No model.)

To aZZ whom it may concern.-

Be it known that we, JOHN CLYDE and ROB- ERT THOMAS CLYDE, citizens of the United States, residing at Marion Center, in the county of Indiana and State of Pennsylvania, have invented certain newand useful Improvements in Wrenches, of which the following is a specification.

all as hereinafter more fully described and.

claimed and as illustrated in the accompanying drawings, wherein- Figurel is a side elevation of this tool complete. spective detail, of the stationary jaw to illustrate the claw. Fig. 4 is a central vertical longitudinal section through the cross-head and handle. Fig. 5 is a section through'the handle at right angles to the line of the section in Fig. 4. Fig. 6 is a cross-section of the handle taken through the spring. Fig. 7 is an end view with the jaws partly approximated. Fig. 8 is a perspective detail of the cam-rin g. Fig. 9 is a similar detail of the end ferrule. a

Referring to the said drawings, 1 designates the body of this wrench, which body is square in cross-section and carries the stationary jaw 2 at its outer extremity. The operative end of this jaw is beveled, as usual, on its outer side, and longitudinally into this end is cut a dovetailed opening 3,'which by reason of said bevel presents a sharp angle, as seen in Figs.

2 and 3, the whole. thus'constituting a claw for pulling nails and the like.

5 is the movable jaw, having two collars 6 surrounding the body 1, and 7 is the usual screw, with thu1nb-wheel 8, for setting this aw.

Upon the inner end of the body 1 is shrunk Fig. 2 is an end view, and Fig. 3 a peror otherwise secured a cross-head 11, in one end of which is a socket-bearing 12 for the pin 9, which forms the axis of the screw 7, as usual, and through the other end of which passes a connecting-screw 13 for a purpose to appear below. Beyond said cross-head the body 1 is reduced, rounded, and threaded to form a stem 14, receiving the nut 15, as seen in Fig. 4:.

21 is the tubular handle, preferably of wood, with metal ferrules where necessary, one of which bears against the cross-head and has a hole 22 for the screw 13. The reduced stem 14 is journaled through this ferrule and extends axially through about half of the handle, in which it is also journaled. The remaining half is transversely slotted, as at 23, forming a chamber into which said stem projects and wherein it receives the nut 15. 24 is another ferrule, of cup shape, covering the lower end of the handle and closing said chamber withthe exception of a slot 25, in line with the slots 23 therein, and 26 are the bodies of two jaws which stand within said chamber, project through said slot 25, and have heads 27 beyond the latter, provided with notched adjacent faces 28. The bodies of these jaws are thrown normally apart by a spring 29, of any suitable character, which is interposed between them, and a set-screw 30 may take through the ferrule 24: behind either jaw (or each jaw) for limiting its outward and assisting its inward movement, if desired.

Although any suitable means may be provided for approximating the jaws just described, we prefer to employ the cam-ring best shown in Fig. 8. This comprises a plain ring 31, traveling in agroove or notch around the corner of the ferrule 24, and a disk 32 at the outer end of the ring, out with an opening 33 of the shape shown in Fig. 7, so as to form a double eccentric. The inwardly-projecting flanges or parts of'the disk 32 around said opening stand beneath the heads 27 of the spring-jaws, by which means the cam-ring is held in position.

In use the claw is obviously for the purpose of drawing nails and the like. The movable jaw is set in the ordinary manner and the monkey-wrench also used. in the ordinary way; but when used the handle must be locked against rotation by screwing the connectingscrew 13 through the cross-head and into the handle. It very frequently occurs, however, that in using a monkey-wrench the nut turns so easily most of the distance on its bolt that it is laborious to employ the usual jaws until it becomes necessary. Again, instances frequently arise where a monkey-wrench cannot be used at all, ora tool is demanded which can be more quickly applied to the nut than by the slow method of moving the jaw by ascrew. The axial wrench at the other end of our tool is then brought into play, its jaws passed over the nut, and the cam-ring turned to move them inward into engagement with the corners of the nut, the screw (or screws) being set if the nut is very tight. The

-connectin -screw 13 is then ti htened and the jaw 2 may be grasped and turned to turn the handle, or the connecting-screw may be loosened, the body 1 used as a handle, and the handle, with its wrench, turned as on a swivel around the stem 14, and this brings us to another feature of our invention.

It frequently happens that tools come out of their handles and cannot be replaced im mediately with suflicient strength for renewed use and also that the workmen may have the tool (such as a bit) without any handle. In any event it will be clear that the axial wrench above described can be readily and} quickly employed as a temporary tool-h andle,

and if used as a bit-stock the connecting-j screw is loosened, and the entire tool forms? a not unhandy substitute for the ordinary} brace.

All parts are of the desired sizes, shapes,i proportions, and materials, and considerable, change in the specific details of construction j may be made without departing from the prinj ciples of our invention.

What is claimed as new is 1. In a wrench, the combination with two members swivelly connected on an axial line, and jaws at the outer end of one member; of a cross-head secured on one member adjai cent the inner end of the other, and a screw; passing through said cross-head substantially parallel with the axis and removably entering the other member at a point remote from its axis, as and for the purpose set}. forth. 1

2. The combination with a body, and a cross-head fast thereon; of a handle swiveled on the body, means connecting the cross-head and handle for locking them against rotation when desired, and a wrench at the remote end of the handle, as and for the purpose set forth.

3. In a wrench, the combination with an angular body having a reduced and rounded stem, and a cross-head fast on the body; of a handle swiveled on said stem, a connectingscrew through one arm of the cross-head into the handle, and an axial wrench in the remote end of the latter, as and for the purpose set forth.

4. In a wrench, the combination with a monkey-wrench body having a rounded stem, a handle having one part journaled thereon and transversely slotted beyond the same, a nut on the stem within the slot, a cross-head on said body, and independent detachable connecting means passing through said crosshead and into the handle; of two jaws whose bodies stand within said slot and whose heads extend beyond the end of the handle and have notched adjacent faces, and means for approximatin g and separating said faces, as and for the purpose set forth.

5. In a' wrench, the combination with a handle transversely slotted, a cup-shaped ferrule fast on one end thereof and having a slot registering with that in the handle, a body swiveled in the other end of the handle, and independent means forlocking the body and handle when desired; of two jaws whose bodies stand within said slotted handle and project through the ferrule and whose heads are beyond the latter, and means for approximating and separating said heads, as and for the purpose set forth.

6. In a wrench, the combination with a handle having a transverse slot, and a cupshaped ferrule with a cross-slot in its end in line with thatin the handle and a notch around its corner; of two jaws seated in the handle 5 and projecting through the slot in the ferrule,

a distending-spring between the jaws, a camring-turning in said notch and having camfaces outside said jaws, and means for holding this ring in place, all as and for the purpose set forth.

7. In a Wrench, the combination with a handle, a slotted ferrule covering the end thereof, a pair of normally-separated jaws whose bodies project through the slot and whose enlarged heads stand remote from the ferrule, and a screw through the latter at one end ofsaid slot; of a cam-disk turning on the ferrule beneath said heads and provided with an opening of double 'eccentric shape whose cam edges simultaneously engage theouter edges of said jaws, all as and for the purpose set forth.

In testimony whereof we affix our signatures in presence of two witnesses.

JOHN CLYDE. ROBERT THOMAS CLYDE.
