PIPE-WRENCH.

SPECIFICATION forming part of Letters Patent No. 669,672, dated March 12, 1901.

Application filed J' 11116 8,1900. Serial No. 19,557- (No model.)

To all whom #777,011] concern.-

Be it known that 1, WILLIAM E. WILLIAMS,

a citizen of the United States, and a resident of Adrian, county of Bates, and State of Mis- 5 souri, have invented new and useful Improvein ents in Pipe-Wrenches, of which the following is a specification.

My invention relates to pipe-wrenches; and the object of my invention is to produce a pipe-wrench of strong simple construction and capable of a wide range of adjustments. I attain this object by the construction shown by the accompanying drawings, in which- Figure 1 is a side elevation of my wrench with one of the sleeves partly in section, the jaws engaging a pipe, which is shown in section, and a nut at the other end. Fig. 2 is an edge elevation of the wrench with the lower pair of jaws extending toward the observer;

The wrench consists of two parallel bars 1 and 2, provided on their contiguous faces with a series of teeth or serrations 3, adapted to interlock with one another, as shown in Fig. 1. The bar 1 is provided at one end with a jaw 5, having a serrated face 6 for engaging a pipe, and at its other'end with a jaw 7, having a curved smooth face 8 for engaginga pipe. The other bar2 is provided at one end with a smooth jaw 4, adapted to coact with jaw 5, and at its opposite end with a jaw 10, having a curved serrated face 9, adapted to coact with jaw 7.

- The bars 1 and 2 are loosely secured to each other by two sleeves 11 and 12, having slots therein, which embrace the straight central portions of said bars. Said sleeves 11 and 12 are preferably integral with the bars 1 and 2, respectively, as shown in Fig. 1. Sleeves 11 and 12 are provided with bosses 13 and 14:, 4o tapped for thumb- screws 15 and 16.

In Fig. 1 the sleeve 11 is shown partly broken away to show the width of the slotin said sleeve.

It will be seen that a suflicient space 17 is provided between the side of the slot and the 5 bar 1 to permit the disengagement of the teeth 3 when the screws are retracted, as the slot in sleeve 11 is likewise wider than the bar 2. The jaws are all of greater width than the bars 1 and 2 and form shoulders 18 and 19 with said bars.

The adjustment of the wrench is easily effected by retracting the screws 15 and 16 and separating the bars 1 and 2 and sliding them past each other until the jaws are in the desired position. Then the screws are tightened up and the jaws of the wrench are immovably secured with relation to each other by theinterlocking of the teeth. I may em ploy ratchetteeth for this purpose without departing from the scope of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

A pipe-wrench comprising a pair of bars normally in contact with each other, each bar having pipe-jaws formed at the ends thereof and having a straight intermediate surface between said jaws, transverse teeth formed throughout the length of said straight surfaces, said surfaces being adjacent to each other, a sleeve carried by each of said bars adapted loosely to embrace the other bar, and thumb-screws mounted in said sleeves for setting said bars together, substantially as described.

In testimony whereof I aflix my signature in the presence of two witnesses.

WILLIAM E. WILLIAMS.
