WRENCH Filed Dec. 8, 1954 JZIVENTdC flee/w: Jjwrr By flaw 5.924%

Irma/5v Patented Oct. 22, 1935 UNITED STATES ATE'i Fries 3 Claims.

wrenches and the main object is to provide a wrench in a simple and practical form in which the jaws are rotatably mounted on the handle for adjustment to various angular relationships whereby the wrenching or twisting action on the work may be applied by either swinging the handle laterally or turning it on its axis as best suited to the work.

Another object is to provide a wrench suitable for use inside a pipe or other work as well as outside for nuts, bolts and the like.

A further object is to provide a wrench of this kind comprising a handle, a serrated inner jaw and an arcuate outer jaw hinged thereto and serrated both inside and out for gripping work either interiorly or exteriorly, the said inner jaw having a shaft journaled through the handle at one end and locked against axial displacement therein and carrying a serrated head opposite the jaw assembly.

With these and other objects in view the invention resides in the novel construction and arrangement of parts as hereinafter fully set forth and claimed, reference being had to the accompanying drawing wherein:

Figure 1 is a side view of the wrench partly in section to show the interior arrangement.

Figure 2 is a fragmental elevation showing the jaws turned to another position relative to the handle and gripping a nut for turning the same.

Figure 3 is an end view showing the jaws arranged for gripping the inside of a pipe which is indicated in section.

Referring now with more particularity to the drawing my wrench comprises a handle I having a sleeve 2 at one end through which a cross rod 3 'is slidably mounted in well known manner for con- Venience in turning the handle and having a diametrically extended bearing aperture 4 near its other end communicating with an axially and inewardly directed spring socket 5.

An inner jaw 6 having an arcuate and serrated gripping face 1 hasa stud or shank 8 extended from its opposite and flat face 9 and journaled freely through the aperture 4 in the handle. At the opposite end of the shank 8 a head I is formed either integrally or separately and fastened in place and this head has an arcuate and serrated M in the spring socket as shown. This arrangement allows the shank 8 and the jaw 6 to turn freely but frictionally holds the parts in any adjusted position.

An arcuate outer jaw l is provided and is ser- 5 rated on both its inner and outer faces 86 and I1 and at one end is forked or cut away to provide spaced bearing ears l8 which are adapted to receive and embrace the inner jaw 6 near one end thereof. This end of the jaw 6 is rounded as 10 shown at H! and the outer jaw is hinged in place thereon by a hinge pin or rivet 20 passed through aligned apertures 2| in the ears l8 and the jaw 6.

The outer jaw I5 may thus be swung toward or away fro-m the inner jaw 6 so as to accommodate a nut or other work of most any size as indicated at A in Figure 2. The nut thus placed between the jaws will be gripped by these jaws as the handle is pulled or swung laterally in the direction indicated by the arrow B or will be likewise gripped and turned by simply rotating the handle I on its axis when it is swung to the position relative to the jaw as shown in Figure l. The gripping of the nut by the jaws is' caused by the eccentric location of the hinge of the outer jaw as the handie is turned as will be readily evident. Of course, the serrations on the jaws enable them to grip a pipe or round object as well as the nut shown.

For use inside a pipe or spud as indicated at C in Figure 3, the outer jaw 15 is swung over against the inner jaw 6 presenting the serrated outer face of the former for engagement with therounded inner periphery of the pipe. The rounded and serrated face i l of the shank head I!) then engages the pipe interiorly and the pipe may be gripped and turned by turning the handle I which in this case is swung so as to enter up into the pipe as shown. The hinge point of the outer jaw is now so located that as the wrench is turned as indicated by the arrow D this jaw is faced outward and the jaws wedge against the pipe.

The wrench is thus seen to lend itself to use both interiorly and exteriorly of. the work and due to the swiveling of the jaws on the handle the tool may be used in many locations where it would be impossible to swing the handle but where the handle may be turned on its axis.

While I have herein set forth a certain preferred embodiment of my invention, it is understood that I may vary from the same in minor structural details, so as best to construct a practical device for the purpose intended, not departing from the spirit of the invention and Within the scope of the appended claims.

I claim: 7

1. In a device of the kind described, a handle having adiametrically extended aperture near one end,-a shank journaled through the said 'bearing aperture, a jaw assembly mounted on one end of the shank and including a hinged arcuate jaw serrated on its inner and outer rounded faces, and a head on the other end of the shank and having a rounded and serrated outer face.

2. In a device of the kind described, a handle having a. diametrically extended bearing aperture adjacent one end" and a spring socket entering the said aperture, a shank journaled through the said aperture and having a peripheral groove in alignment with the said spring socket, a ball in the socket and a spring in the socket urging the ball into the said groove, an inner jaw formed on one end of the shank and a head formed on the other, the said inner jaw and head having the1r outer faces rounded and serrated, and an arcuate outer jaw hinged to one end of the inner jaw and serrated on both its inner and outer concave and convex faces.

3. In a device of the kind described, a handle having a diametrically extended aperture adjacent one end, a shank journaled through the aperture, a rounded and serrated inner jaw formed on one end of the shank, a rounded and serrated head formed on the other end of the shank, and an arcuate outer jaw hinged at one end to the inner jaw on the shank, the said outer jaw being ser-' rated on both its inner and outer faces.
