1. FINDLEY.
PIPE WRENCH.
APPLICATION FILED APR. 15. 1921.
1,390,1 12, PatentedSept. 6, 1921.
gwuentoz John Findley ft toil.
PiPE-WRENCH.
Application filed April 15, 1921.
T 0 aZZ whom it may concern:
Be it known that 1, JOHN FINDLEY, a citizen of the United States, residing at De Soto, in the county of Johnson and State of Kansas,have invented certain new and useful Improvements in Pipe-Wrenches, of which the fOllOWiIlg is a. specification.
My said invention relates to an improve ment in pipe wrenches and it is an ob'ect of the same to provide a device of this 0 aracter which may be adjusted with great readiness and which shall operate with certainty.
Referring to the accompanying drawings, which are made a part hereof and on which similar reference characters indicate similar parts,
Figure 1 shows my device in perspective,
and
Fig. 2 is an elevation of the same in working relation.
In Fig. 1 reference character 5 indicates the body of the wrench having an enlarged handle 6 and a terminal jaw 7 The handle is grooved at its front side at 8 and the jaw is also grooved as at 9. A slidable bracket 10 embraces the body and has a flat face 11 rounded off at the ends and bearing against the back of the body. At its forward end the bracket carries a pivot 12 on which is a rotary device 13. This device has teeth let with notches between them, these teeth being adapted to engage with the teeth between notches 8 for adjustment of the rotary member 14 relative to the jaw 7. ln this manner the rotary device forms a pinion co-acting with rack-teeth on the body 5 for adjustment while at the same time the member 14; constitutes the rear jaw of the wrench.
Specification of Letters Patent.
Patented Sept; 6, 1921..
Serial No. 461,466.
As will be evident from the drawings the ridges on the jaw 7 cooperate with the; ridges on the member 143C to grip the surface of a piece of pipe or other cylindrical work 15 in the usual manner. When the wrench is turned in the direction of the arrow the jaws 9 and 14 will tend to turn in the direction of the arrow 16 and thus grip the pipe with increasing force. A reverse movement of the wrench will loosen the jaw 1 and start to back it off from the work and it may then be moved back with its bracket 10 to re lease the wrench from the work.
Having thus fully described my said invention, what I claim as new and desire to secure by Letters Patent, is:
A wrench having a body, an enlarged handle thereon, an integral jaw projecting at an angle from the body and having a roughened face, a bracket slidably embracing the body provided with a flat face and rounded off ends and bearing against the back ofthe body, a rotary member carried by said bracket having a roughened face to form the opposing jaw of the wrench, the roughened face of said member co-acting with the roughened face on the body of the wrench to lock the movable jaw in adjusted position, substantially as set forth.
In witness whereof, I have hereunto set my hand and seal at De Soto, Kansas, this 11th day of April, A. D. nineteen hundred and twenty-one.

HARRY E. MILLER, C. S. HAMBLETON.
