WRENCH.

SPECIFICATION forming part of Letters Patent No. 478,121, dated July 5, 1892.

Application filed March 3, 1892.

To all whom it may concern:

Be it known that we, WILLIAM MILLER, of Hillsdale, Ilillsdale' county, Michigan, and WILLIAM S. DUVALL, of Washington, District of Columbia, citizens of the United States,

have invented a new and useful Wrench, of

which the following is a specification.

This invention relates to improvements in rod and pipe wrenches, the objects in View being to provide a wrench of great simplicity and durability, that may be readily applied and as readily grip rods and pipes located in various positions and willaccommodate itself to rods and pipes of various sizes.

A further object of the invention is to adapt the wrench to serve as a wire or rod cutter, and, furthermore, to adapt the same to operate upon perforated glands as employed in packing-boxes for pistons and other rods.

Vith these objects in view the invention consists in certain features of construction hereinafter specified, and particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a per spective of a wrench constructed in accordance with our invention. Fig. 2 is a plan view illustrating the manner of applying the same to a gland. Fig. 3 is an elevation illustrating the manner of employing the wrench as a wire-cutter.

Like numerals of reference indicate like parts in all the figures of the drawings.

The wrench-stock 1 has its outer end curved, as shown, to form the stationary jaw 2, the same being provided with a series of teeth 3, disposed toward its extremity and formed transversely upon its outer or convex face. The inner edge of the jaw is curved or quad- {ant-shaped, and preferably terminates in a 5 designates the curved movable or pivoted jaw, the same having its inner face provided with a series of transverse teeth 6, oppositely disposed to the teeth 3 01 the jaw 2 and adapted to coact therewith in gripping a pipe, rod, or other cylindrical object. In rear of the jaw 5 its shank is split or divided, forming bifurcations. These bifurcations are spread apart,

as shown, to receive the stock 1. The bifur- Serial No. 423.620. (No model.)

cation 7 is continued some distance beyond the bifurcation 8, and a pivot pin or bolt 9 passes transversely through the two bifurcations and the stock. That corner of the bifurcation -7 of the shank which contacts with the adjacent corner of the stock 1 is made perfectly square to form a sharp cutting-edge 10, and a similar cutting-edge 11 is formed on the said adjacent corner of the stock.

In operation as a wrench for rods, pipes, &c., it is simply necessary to engage the jaw 5 under or over a rod or pipe and swing the stock 1 toward an alignment with said jaw, causing the stationary jaw 2 to bite or bind upon the pipe. A continued motion of the stock 1 carries with it the rod or pipe, and

thus the same is manipulated.

In Fig. 2 we have illustrated how the device may be employed for removing glandnuts. In the said figure, 12 designates the gland-nut, provided, as is usual, with peripheral countersunk cavities 13. The two jaws of the wrench are closedthat is, the terminals 7 and 8 lie alongside of the stock 1and the lug 4 is applied in any one of the cavities 13 of the aforesaid gland-nut. Now by pressing the inner edge of the curved jaw 2 closely against the periphery of the nut and operating the stock 1 the nut may be either applied or removed, after the ordinary manner of accomplishing the same, through the well-known gland-nut wrenches made especially for this purpose.

In Fig. 3 we have illustrated how the device may be employed as a wire-cutter, and in such instance it is preferable to rest the movable jaw 5 upon abench or other support .and lower the stock 1 at its inner end, so that the long terminal 7 and the stock separate. A wire being inserted between the separated stock and terminal 7, it is only necessary in order to sever said wire to raise the inner end of the stock in an attempt to bring the two jaws together, so that the edges 10 and 11 are forced by each other andact to sever or cut the wire, which we have indicated in position therein. From this description it will be seen that we have provided a wrench for pipes and rods of cheap and simple and du- Having described our invention, what we claim is 1.

edge and its outer end curved to form a stationary jaw having an inner eoncaved and outer convexed face, the latter provided with teeth, said jaw at its outer extremity and concaved side being reduced to form a eylindrical lug adapted to engage the perforationsin a gland-nut, of a curved jaw having its shank bifurcated and spread to embrace the stock, and pivoted thereto in rear of its bent end, one of said bifurcations being extended be yond the pivot some distance to form awirecutter and having one of its corners squared and adapted to coact with the squared eutting-corner of the stock, substantially as specified.

In testimony that we claim the foregoing as our own we have hereto aflixed our signatures in the presence of witnesses.
