Application filed June 27,

To all whom it may concern:

Be it known that l, TVILLIAM D. l'r'rnL, citizen of the United States, residin at Houston, in the county of Harris and tate of Texas, have invented certain new and useful Improvement in a l l rench, of which the following is a specification.

This invention relates to new and useful improvements in a wrench.

()ne object of the invention is to provide a wrench specially adapted for use in cases where the nut or other part to be turned is located at a comparatively inaccessible place.

Another object of the invention is to provide a wrench having a handle formed with an angle or curve so that when the wrench is used in places where the range of movement of the handle is limited the wrench will have a greater active range than would be the case were a wrench having a straight handle used.

Another object of the invention is to provide a wrench whose head has a swiveling connection with the handle.

lVith the above and'other objects in view the invention has particular relation to certain. novel. features of construction, opera tion and arrangement of parts, an example of which is given in this specification and illustrated in the accompanying drawings, wherein Figure 1 shows a plan view of the wrench illustrating in dotted lines the different positions it may occupy in use, and

Figure 2 shows a longitudinal sectional view of the wrench head showing the handle attached.

In the drawings the numeral 1 designates the head of the wrench which is formed with a socket 2 to receive a nut, bolt head, Or the like. T he wrench handle is bent, as shown, forming what may be termed the wrench section 3 and grip section at, said sections having an angular relation to each other. The wrench head has a transverse socket 5 into which the section 3 of the handle is fitted, and the section is formed with an annular groove 6 provided to receive the "7 1922. Serial No. 571,206.

transverse key 7 which is driven through said head and which prevents the detachment of the head from the handle.

Often times the nut is located so that the handle must work between stationary parts, as for example 8 and 9, and if a wrench having a straight handle is used it often happens that the distance said handle can move will not be sufficient to turn the nut far enough to obtain a new hold on it. By using a curved handle, such as herein shown, the active range of the wrench may be actually increased. In use the wrench is applied to the nut as indicated in full lines in Figure 1, and then moved to the position indicated by the dotted lines 10. .The handle is then swung around one-half turn until it occupies the position indicated in dotted lines by the numeral 11 and is then moved on to the position indicated in dotted lines as shown at 12. The nut will thus be turned much further than would be the case if a straight handle had been used and moved from the stationary part 8 to the stationary part 9. The range of the wrench is thus in effect greatly increased.

What I claim is z- A wrench including head formed with two sockets, arranged at approximately right angles to each other, one of said sockets being formed to receive a nut, a wrench handle bent so as to form an obtuse angle at a point intermediate its ends, and thus formed with bearing section, and a grip section, said bearing section. fitting into the other socket and having an annular groove and a transverse key through said head which fits into said groove and prevents the detachment of the head from the handle, said head being freely rotatable around the axis of the bearing section.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
