Applicetion'led January 8, 1908, Seriel'No. Y409,893. Renewed October `1, 1908. Serial It'a'455f128.

To all who/m 'it may concern: Y

Be it known that I, ALFRED CARLETON SMITH, a citizen of the United States, resid-- ing at Dobbs -Ferry, in the county of Westchester and State of New York, have .invented' certain new and useful Improvements in Wrenches.; and I do hereby declare the following tofbe-a full, clear, and exact description of thejiinventiom such as will enable others skilled in the art to which it apper tains to make and use the'same.

My invention relates to new and. useful improvements in wrenches, and more particuand my Objectis to provide a wrench of this A1 further 'abject is to pro-vide a flexible handlefor the socket of the wrench, whereby A further object is to provide means for securing the handle lto the socket.

Other objects and advantages will be hereinai'ter referred to 'and more particularly pointed out in the claims. Y l v In the accompanying drawings which are made a partei-.this application, Figure 1 is and the object to which the same is secured,

the wrench on an enlarged scale, and, Fig. 3 isa sectional view as seen on line 3-3,

eferring to the drawings in which similar reference numerals-designate corresponddicates a tubular member and 2 an object to whichthe same is to be secured, the lower end of the tubular member being closed and ing exteriorly threaded to engave the threads in the bore. The upper end oiP the bolt 4 is provided with a head 5, which is preferably square incross section, with which is adapted toengag'e .a body portion 6 of a wrench;

said-body portion having a socket 7 therein l to receive the head 5,. and to the body porff. tion 6 is secured a handle- 8, by which me iis thebody .portionis introduced into the open directed into engagement with thehead 5, the extreme upper end of the handle being provided with a cross bar 9, whereby the PATENT oFFicE.

body portion may be turned and the bolt'entered into or removed from the'object 2. The tubular member 1 is provided with a curvature 10 at a point in its length, thereby- A disposing the lower end of the tubular member out of alinement with the upper end thereof, and, when objects of this class are encountered, it is necessary to provide a exible handle, so that the body portion may be directed out of alinement with the cross bar and, at the same time, provide a sufficiently rigid handle to cause the body portion to iturn the bolt, when-the cross bar is rotated.

To this end, I-provide a plurality of strands f 11, preferably of wire, which are secured at Y their lower end to the body 6 by disposing Ithe lower ends of the strands through an @opening 12 in the head, while the upper ends the strands aresecured 1n any preferred manner to the cross bar" 9.

'Surrounding the strands 11 are spirally disposed coverings 13 and 11, 'the inner covering 13 being'oppositely wound to the outer covering 14, whereby the tension of one of the coverings will be opposed to the tension of the oppositely wound covering, when the handle is turned in opposite directions.

The lower ends of the coverings 13 and 14 are provided with extensions 15 and 16, respectively, which extensions extend downwardly through ways 17 in the body 6, the lower endsof the extensions 15 and fbeino' vlbent at-right angles to the extensi nsand seated in notches 18, thereby positively ,'se'- curing the coverings to the body 6.

The opposite ends of the coverings are secured to thecross bar 9 in any-suitable manner, while the body 6 isprovided with an up wardly extending thimble 19, into which the lower ends of the coverings are inserted. 1

The coverings 13 and 14 are preferably formedl of spring metall andl closely coiled around the strands 11, the coils thereof being directed in opposite directions to provide suliicientlrigidity to the. handle to operate the.bolt as described.

Bythis constructionof'wrench, it willA be seen that thelbolts may be readily .o erated not be employed and, by constructin y handle in the manner shown, it -wi Abe readily seen that the same may lbeloont at where a wrench having a rigid hand e could the l and means surrounding said Strands to limit I f thebody and cross bar in 'the relative twisting of the strands between either direction when the cross bar is rotated.

2. In a wrench of the class described, the

I combination with a body portion having a socket therein and an opening through the said strands y body portion; of 2o strands secured insaid opening and extendin upwardly from the body,A a cross bar at t e upper end of said strands and an inner and outer covering for adapted to limit the relative twisting of the strands between the body and cross bar in either direction when the cross bar is turned. 7

. 3. In a wrench of the class described, the

l combination with a body portion having an opening therethrough; of strands secured in said opening and extending upwardly therefrom, a cross bar at the upper end of said strands and iiexible coverings surrounding i @casca said str.- bds and secured at their 4ends, respectivey, to the body portion and cross bar.

4. In a wrench of vthe class described, the combination with a body portion; of strandsl secured to said body portion, means at the upper ends of the strands to impart rotating movement thereto, spirally disposed "ie'xible coverings surroundlng said strands and 40 means to secure the coverings to the body portion. 1

5. In a wrench of the class described, ,the/

combination `with a body; of strands secured to said body, an inner and outer covering surrounding said strands, said coverings being spirally disposed -and having' their tension opposed to each other and secure the coverings to the body.

6. In a wrench of the class described, `the 50 combination with a body portion havin a socket, strands' secured-to saidbody an `aY cross bar at the upper endsoi? said strands;

of means to limit the relative twisting of the strands between ,the body and cross bar when said bodyandcross bar are rotated.
