ARLO E. RICE, OF MARCUS, IOWA.

PIPE-WRENCH.

' Specification of Letters Patent.

Patented Sept. 28, 1915.

Application filed July 24, 1915. SerialNo. 41,711. I

AnLo E; RICE, a citizen of the United States, residing at Marcus, in the county of Cherokee and State of Iowa,

have invented certain new and useful Improvements in Pipe-Wrenches, of which the following is a specification,

reference being had to the accompanying drawings.

This invention comprehends oe'rtainvnew 0 and useful improvements in and has for its primary ob ect a simple, rable and eflicient construction of this character, the p cheaply manufactured pipe wrenches,

dudevice of arts of which can be very and readily assembled and are not liable to get out of order,

and which desired kind of grip and leverage, ing to the particular are so connected as to allow any accordrequirements of the work with which the wrench is used. And

the invention also a ims to generally improve devices of this class so as to render them more useful and commercially desirable.

lVith these and other objects in view, as

will more fully appear as the description proceeds,

constructions, tions of the parts more fully describe the invention consists in certain arrangements and combinathat I shall hereinafter and claim.

For a full understanding of the invention, reference is to description and which,

Figure 1 is a sid accompanying drawing,

be had to the following e view of a pipe wrench .embodying the improvements of my invention. Fig. 2 IS a detail view of one of the jaws and handles, view of the other a Corresponding and to in the following nated in the view and Fig. 3 is a similar w and handle.

like parts are referred description and desigs of the accompanying drawing by like reference characters.

My improved pipe wrench comprises an angular aw 1 which 1s composed of an outer member 2 and an inner member 3 integrally connected together,

said jaw being preferwith a handle a and beposed in offset relation remity of the outer member 52 terminating in substantially longitudinal alinement with edge of the angle with alligator teeth desired direction and degree,

the other handle of the tool.

6 designates said handle. The inside of the jaw 1 is formed projections, slanting tne as shown.

55 This is bifurcated at one end to form a prong 7 which constitute s the other jaw of the device and which is designed to embrace the members 2 and3, as shown, said prong bers of the bifurcations all slant in the same direction. Theprong 7 is formed in each of its members with a plurality of transversely extending apertures 9. the apertures of one member of the prong registering with the apertures of the other member thereof, and the jaw 1 is also formed with a corresponding series of apertures 10, in each of its members 2 and 3, said apertures also preferably extending somewhat into the handle 4-. A pivot pin or bolt 11 is adapted to be inserted through any registering apertures 9 and 10, so as to couple the parts together in any desired position, whereby the required grip and leverage will be secured.

From the foregoing description, in connection with the accompanying drawing, the operation of my improved pipe wrench will be apparent.

In the practical use of the device, the coupling pin 11 is inserted through any desired registering apertures 9 and 10, according to the size or other requirements of the pipe, rod or the like with which the wrench is designed to engage, and with either set of teeth 8, as desired, co-acting with the teeth 5 of the jaw 1 so that when the handles 4 and 6 are drawn together about the work the same will be securely clamped.

It will thus be seen that I have provided a very simple and durable construction of pipe wrench, the parts of which may be easily connected at any desired adjustment, and that each part of the wrench may be formed of a casting and very cheaply manufactured.

lVhile the accompanying drawing illustrates what I believe to be the preferred embodiment of my invention, it is to be understood that the invention is not limited thereto, but that various changes may be made in the construction, arrangements and pro portions of the parts without departing from the scope of the invention as defined in the appended claims.

Vhat is claimed, is:

1. A wrench of the character described, comprising an angular jaw formed on the inside edge of the angle with teeth, said jaw being also formed with apertures extending transversely therethrough, a handle connected to said jaw, another handle, a prong connected to the said last-named handle, and embracing the jaw and formed with teeth and with transversely extending aperturesadapted to register with the apertures of the aw, and a pivot bolt. insertiblein thev registering apertures of the jaw and prong, for the purpose specified.

A wrench of the character described, comprising an angular jaw embodying two members each of which is formed with apertures extending transversely therethrough, a handle connected to said jaw, the jaw being disposed in offset relation to, the handle,

another handle, a prong formed on one end of said last-named handle and embracing said jaw and formed on its edges with teeth, said prong being also formed with apertures extending transversely therethrough 'and adapted to register with the apertures of the jaw,and a pivot bolt insertible in the registering apertures of the prong and jaw, as and for the purpose set forth.

In testimony whereof I hereunto afiix'my signature in the presence of two witnesses.
