To all whom'z't may concern; 7 y

Be it known that I, HERMAN A. WnLoH, a citizen of'the United States, residing at Goldwater, in the county of Gon ancheand State of Kansas, have invented certain new and useful Improvements in trenches, of which the following is a specification.

'- This invention-relates to wrenches and more particularly to an improved wrench es:

pecially adapted for use to tighten and loosen the nut on the various parts of automobiles and particularly the Ford automobile.

One of the principal objects of the invention is to provide an improved wrench adapted to permit the user to obtain a hold of the nuts on the automobile engine which are not readily accessible with the ordinary socket wrench and which are not readily turned by the use of the ordinary S-wrench.

The invention further aims to provide an improved wrench having one end of the usual socket formation and its opposite end shaped similar to the end of an ordinary S- wrench, the intervening parts being so arranged as to permit the socket to serve as a handle for the wrench when the opposite end is being used, the latter being so disposed as to permit it to be readily inserted in places which are ordinarily inaccessible with the ordinary types of wrenches.

A further object of the invention is to provide a device of this character which consists of comparatively few parts and is simple in construction but durable and well adapted to withstand the rough usage to which devices of this character are ordinarily subjected.

For a full description of the invention and the advantages and merit-s thereof reference is to be had to the following de scription and accompanying drawings, in which Figure l is a perspective view of. the wrench constructed in accordance with my invention.

Fig. 2 is a plan view illustrating the relative positions of the socket.

Referring to the drawings, wherein is illustrated the preferred form of my inven tion, in which like numerals of reference indicate corresponding parts throughout the several views, the shank 1 may be of any desired length and has one end extending at right angles from the main portion of the shank thereby providing a right angularly disposed extension 2 which carries a socket 1 Specification of Letters Patent.

3. This socket is adapted to receive a nut in the manner common to socket wrenches.

The opposite end'of the shank l is flattened and longitudinally curvedto provide the arcuate arm 4 and the end of this arm carries a laterally projecting nut engaging member 5 which is somewhat similar to the ,ordinary S-wrench: To give strength to the device, the bar 4 is preferably twisted as indicated at 6 so that the member 5 does not project laterally by means of a simple bend which would be likely to be contorted when the wrench was placed under a strain. By. twisting the two connected members l and 5 so that the inner end of the member 5 is curved around the end of the member 4: and projected laterally therefrom, a turn ing movement may be given to the member 5 without danger of bending or contorting the connected parts at their juncture. The position of the member 5, however, makes it especially adapted for use in reaching nuts which are ordinarily not accessible with a socket wrench or with an ordinary monkey wrench. The bar 1 is disposed considerably above the member 5 when the wrench is in use and the socket 3 may be grasped to be used as a handle for turning the device in a crank like manner to turn the nut. The

-member 5 has its end notched as indicated at 7 to receive the nut. The member 5 also serves as a convenient handle to operate the wrench when it is used as a socket wrench to remove the nut on the wheel rim or the nut on the top of the automobile engine. The device, therefore eliminates the necessity of two separate tools and both ends of the wrench have their double function, namely use as a handle and nut engaging member.

The foregoing description and accompanying drawings have reference to what might be consideredto be the preferred or approved form of my invention. I desire it to be understood that I may make such changes in the construction, combination and arrangement of parts, materials, dimensions, et cetera, as may prove expedient and fall within the scope of the appended claims.

Having thus fully described my invention what, I claim as new and desire to secure by Letters Patent, is

1. A wrench comprising a shank having one end provided with a right angularly dis posed socket portion, the said shank having an extension carrying the said socket whereby the latter may be used asa handie, the opposite end of the said shank being longitudinally curved, the end of the said curved portion carrying a laterally projecting nut engaging member having its end notched to receive a nut, the said curved end of the shank maintainingthe said shank in a position considerably above the nut engaging member, the latter being projected laterally from the said curved end of the shank.

2. A Wrench comprising an elongated shank, having an extension projected at right angles from one end of the shank, a socket member carried by the said extension and forming a handle at one end of the said shank, the opposite end of the shank being longitudinally curved, a laterally projecting member carried by the end of the said curved portion of the shank and provided with a nut engaging terminal, the connected portions of the said curved end of the shank,

and the said nut engaging member having a twisted portion to give rigidity to the said curved portion and laterally projecting member at their juncture.

In testimony whereof I afiix my signature 1n presence of tWo Witnesses.
