Application filed March 24, 1919.

To all whom it may concern:

Be it known that I, THEODORE D. ANAG- wos'roronnos, a citizen of the United States, residing at Eunice, in the parish of St. Landry and State of Louisiana, have invented certain new and useful Improvements in renches, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to wrenches or like devices, and the general object of the invention is to provide a very simple wrench which may be cheaply manufactured, which will have a positive grip npon the object engaged, and which may be used for a number of difierent purposes.

A further object is to provide a wrench which includes two separable but coacting heads and shanks, the shanks being exteriorly screw-threaded, and a sleeve having screw-threaded engagement with the shanks so that as the sleeve is turned up 011 the shanks, the shanks will be forced together and the two sections of the head forced toward each other.

And a further object is to provide a wrench of this character with a sectional head formed to provide a large wrench socket, a small wrench socket, and abutting jaws, and coacting wire cutting blades.

Other objects willappear in the course of the following description.

My invention is illustrated in the accom panying drawings, wherein Figure 1 is a side elevation, partly in section, of my improved wrench;

Fig. 2 is a perspective view of one of the heads or jaws of the wrench and part of the shank; and

Fig. 3 is a transverse section through the shanks and the adjusting collar.

Referring to these drawings, and particularly to Fig, 1, it will be seen that my improved wrench is formed in two sections A and B. Each of these sections consists of a head 10 and a shank 11. The inner faces of these shanks abut or contact with each other when the wrench is closed and the exterior arcuate faces of the shanks are screwthreaded. It will thus be seen that each shank is semi-cylindrical in cross section and has on its curved face an interrupted screw-thread complementary to the interrupted screw-thread on the other shank.

Each head 10 is approximately semicircular in form and each head is formed with a Specification of LettersPatent.

three-sided recess 12 which is complementary to a like recess on the other head so that when the heads are disposed in conjunction with each other, a hexagonal socket is formed for the reception of a bolt. Of course, the socket may have other forms than that of a hexagon. Above these recesses 12, the head is formed with a smaller two-sided recess 13 which, when the heads are in conjunction, forms a square socket which is smaller in area than the socket for ned by the recesses 12 and suitable for small nuts or like obj ects. Beyond these recesses 12, each head is formed with a longitudinally projecting portion providing a jaw 1a which coacts with a like jaw formed on the opposite head, these jaws forming pincers and being preferably serrated on their inner faces.

Between these recesses 12 and the shanks 11, the abutting faces of the heads are formed with complementary wire cutting blades 15 and below these wire cutting blades, one of the heads at its junction with its shank is formed with a recess or bore 16. An angular spring 17 is provided, the shank of which spring enters and fits in this bore 16, the body of the spring extending longitudinally of the shanks between'the same, and the outer extremity of the spring bearing against one of the shanks, as indicated in Fig. 1, so that this spring normally urges the shanks away from each other. At the ends remote from the heads, the shanks are provided with a coacting bore 18 andpin 1%) which fits loosely within the bore so as to provide a connection between the shanks, which connection will prevent the shanksfrom being detachable from each other but will permit the shanks to move into or out of angular relation to each other.

Operating upon the shanks is a sleeve or collar 20 which exteriorly may have any suitable form, but which is interiorly tapered from one end toward the other and interiorly screw-threaded.

In the use of this device, it will be obvious when it is desired to open the wrench the collar is turned down to the extremity of the shanks, and when the wrench is to be closed, the collar is turned up on the shanks so as to urge the heads toward each other, and the more the collar is turned up on the shanks, the closer the heads will be drawn toward each other, thus adapting theheads to fit various sizes of nuts or other parts. As will be obvious, the device may be used as a wrench for large or small nuts or bolts having hexagonal or square heads, and may be also used as a hand vise by clamping the article to be held between the jaws 14, as pincers, or as means for cutting wire. The device is simple, can be cheaply 1nanufactured, and has been found very convenient in practice.

I claim A tool of the character described comprising a pair of complementary shanks including sockets at their upper ends, the shanks being exteriorly and longitudinally screwthreaded, one of said shanks having an opening adjacent each end thereof, a threaded collar operatively connecting the shanks to each other, said collar being adjustable longitudinally of the shanks, a spring secured to the other shank and interposed between the shanks adjacent their upper ends, one end of said spring being slidable in the opening in the upper end of the first mentioned shank to properly position the socket ends of the shanks with respect to each other, the remaining end of the spring being freely engaged with the first mentioned shank, and means carried by the second mentioned shank and slidably disposed in the lower opening of the first mentioned. shank to properly position the shanks.

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