BUFORD J. STEEN, OF GOOSE CREEK, TEXAS.

PIPE-WRENCH.

This invention relates t0 new and useful,

improvements in a pipe wrench.

One object of the invention is to provide a wrench of the character described, adapted t0 be used for screwing sections of pipe together, and for unscrewing them. However, the wrench may be used for other similar purposes to which it may be applicable.

Another object of the invention resides inthe provision of a wrench of the character described, which is of simple and cheap construction, and may be easily manipula-ted to turn the pipe sections in either direction in screwing them together, or separat- A further feature of the invention resides in the provision of a wrench which may be readily released from the pipe or other object which may be engaged thereby.

With the above and other objects in view, the invention has particular relation to certain novel features of construction, arrange-` ment of parts and use, an example of which isA given in this specification and .illustrated in the accompanying drawings, wherein:

Figure l, is a side view of the wrench, and

Fig. 2, is a plan view thereof.

Referring now more particularly to the drawings' wherein like' numerals of reference designate similar parts in each of lthe figures, the numeral 1 refers to a Wrench handle, whose operative end is formed into the

arcuate gripping jaws

2 and 3. The jaw 2 is provided on its inner side, `with a recessed bearing 4, wherein the dog 5 is pivoted. The outer end of this dog is toothed, and the dog is seated against the coil spring 6, which operates to hold it projected from the jaw and into engagement Speccation of Letters Patent.

Application l'ed March 4, 1919. Serial No. 280,538.

may be released from the pipe. The jaw 2 3, near its base, has a simil'ar dog 7, which is held projected against the pipe by nieans of the coil spring 8, and near the free end of the jaw 3, there isa similar dog`9, whose outer or operative face is toothed'to engage with the pipe, and which is held in engagement therewith by means of the coil spring 10.4 When the wrench is applied to the pipe, IJthe dog 9 will -pass more than half of the Way around the pipe from the dog 5. Should the handle 1 be then moved in the direction indicated by the arrow, said dogs will engage with the.. pipe and turn same. In order to release the wrench from the pipe, I have provided a release rod 11, which is attached at one end to the inner end of the dog 9, and which projects out through the slot 12, out through the jaw 3. Vhen this rod is pulled in the direction toward the free end of the jaw 3, it will release the ydog 9 from the pipe and the wrench may be then disengaged from said pipe. By reversing the wrench in itsapplication to the pipe, said pipe may be turned in the other direction, the wrench thus being adapted for use in either screwing or unscrewing pipe.

What; I claim is:

A wrench including a handle, a pair of opposed arcuate .jaws integral with the handle adapted to embrace a pipe, there be.- ing recesses in the walls of said arcuate jaws and slots communicating from certain of said recesses to the outer surface of the jaws, a dog pivotally mounted in each of said recesses adapted to grip the pipe, and handles integrally formed with certain of said dogs and protruding through said slots whereby the dogs can be manipulated by hand during operation and springs urging said dogsto grip the pipe.

In'testimony whereof I have signed my.

n ame to this specification in thepresence of two subscribing witnesses.
