WRENCH.

' Application filed April 15, 1926. Serial No. 102,255.

This invention relates to improvementsin wrenches, and the object oi the invention is to provide a wrench that can be instantlyv` changed to fit any sized nut, whereby when I used by mechanics and others moreV satisfactory and quicker results are obtained than' wrench with the filler blades mostly in in my invention is illustrated, 10 designatesy an ordinary wrench as a whole, provided with 'recesses' 11 and 12 of different dimensions at each end, the ends as is well `known being enlarged as at 13 and 14, and the intermediate body portion 15 forming vthe handle portion for the wrench. n

Adjacent the recesses 11 and 12 and in the body portion are slots 16 and 17 spaced from said recesses by solid intervening portions 18 and 19.

Within these slots, pivotally mounted on pins 20. are a plurality of liller blades 21, adapted in inoperative position to lie snugly within the slots and, as illustratedin 1,'Husli with the surface oi' the body portion. These filler blades are provided with recesses or cutouts 22 designed to engage with the shoulder or bridge portions 18 and 19 entrated in Fig. 1, in the recesses 11 and 12 to automatically curtail their size and there- .structed without departing from the spirit` wrench.

abling the blades to iit snugly, as also illusby adapting them to fit bolt nuts of different sizes. According to the size of the nut, one

or more of the blades `21 may be employed. 55 For swinging the blades into operative position I provide thumbnail spaces yor recesses 23 in the sides of the wrench. The

outer ends 24 of the blades are preferablyr slanted to engage with the slanting ends 25 `60 of the recesses 16 and 17 in inoperative position and thus limit the travel of the blades beyond a predetermined point.

From the foregoingy the operation of my wrench will be apparent, as in order to ad- 65 )ust it to fit anysize of nut it is onlypnecessary to swing as many of the blades 21 as may be necessaryto form a clamping means roi* the nutfrom their inoperative position into kone of the end recesses v11 'and 12.

As many changes could be made in the Yabove construction and 4many apparently widely .dili'erent embodiments of my inven-4 tion, within the scope of the claims, conor scope thereof, it is intended'that all matp ter contained in tlie'present specification and laccompanying drawings shall be interpreted in an illustrative and not in a limiting sense.

lVhat I claim as my invention is: 1. A wrench comprising a body portion recessed at one end, intermediately rand centrally slotted, a plurality of liller blades pivotallyk mounted in said` body adjacent to the recess and formed on the under side with recesses to engage with the body, said blades being adapted tobe moved selectively and` collectively ,to render the wrench adjustable and to fit flush with the surface of the 2. The combination with a slotted wrench or spanner provided with enlarged portions ateacli end, one of said enlarged portions being partially cut out or recessed, a plu rality'of blades formed on the under side with recesses pivotally mounted in said slot and adapted to swing across and engage with the recessed enlarged portion to adjust the size of the wrench and to swing in the 0pposite direction flush with the surfaceof the wrench.

In witness whereof I Ahave hereunto set my hand. I
