"WRENCH.

Application filed February 23.. 1916.

'1 '0 all whom it may concern Be it known that I. Joux l). (lonnnn, a citizen of the United States. residing; at .l rederick. in the county of Brown and Htate f South Dakota. have invented certain new and useful Improvements in lVrenches. oi

which the following is a specification, reference being had to th inns. This invention relates to an improved wrench and has for its primary ohject to provide a quick adjustable monkey wrench which is exceedingly simple in its construction as well as highly strong and durable. and is provided with means whereby the adjustable jaw can he securely held in its adjusted position to resist severe strains or pressures devolving thereon'in the use of the wrench. I

It is another more particular object of the invention to provide a Wrench of the above type including a shank having a fixed jaw on one end and teeth on the opposite edges of said shank, a pair of dogs pivot ally mounted in the-inner end of the ad justabl jaw. and bowed spring-s connecting said dogs and normally acting to hold the free ends thereof in enga ement with. the teeth on the wrench shank. pressure upon said bowed springs operating to move the dogs out of engagement with the teeth whereby the jaw may he longitudinally adjusted upon the shank.

With the above and other objects in view. my invention consists in the novel features of construction. combination and arrangement of parts to he hereinafter more fully described, claimed and illustrated in the accompanyinc' drawing in which.

F igure 1 is a perspective view of a. wrench accompanying drawconstructed in accordance with the preferred embodiment of my invention; edge view partly in section;

a horizontal section taken on of Fig. 2.

Referring in detail to the drawing, 5 designates the wrench shank of rectangular form in section, having: a suitable handle indicated at '6 attached to one end thereof. On the other end of the shank 5, the jaw 7 is formed. The opposite faces of the shank 5 are each provided with a longi tudinal series of teeth 8.

9 designates the adjustable jaw mounted for longitudinal sliding movement upon the shank 5 and having a hollow longitudinally Fig. 2 is an and Fig. 3 is the line 3%) Specification of Letters Yatent.

Serial'll'o. 79.65 3.

projecting milension 10 through which the wrench shank is 'oosed. The opposite side walls or the extension l0 corresponding to the toothed fac s oi the wrench shank 5 are n'm'iricd in their inner ends with the recess s orsockets to accomn'iodate the pivot knuckles 13 formed upon one end. of the dogs 19. Pivot pins or bolts 14 are dirjposed transversely through the body walls of the adjustahle jaw and through the knuckles 13. said pins-supporting the dogs lzZ-for pivotal movement.

Relatively thin metal bowed springs 15 are riveted or otherwise secured at their extremities to the corresponding longitudinal edges oi the dogs 152 intermediate of their ends. said springs extending across the 'untoothed .i'aces of the wrench shank These springs normally act to hold the free ends 0'[ the l teeth 8 on the wrench shank and thereby I'Jrevent an inward n ur'en'ient of the adjustable jaw 9 upon the shank with re spect to the fixed jaw 7.

'From the foregoing description. the construetion and manner of operation of the device will he readily understood,

l l 'hen it is desired to adjust the jaw 9, the operator pr. with his tl'iiunh and forefinger upon me central portions 0 respective bowed springs and force-s in: same toward the shank thus \ii'lililif to str: igrhtei'i the rings. The tree ends oi the will t shy he forced outwardly and beyond the ed s of the t. jaw 9 may now he iiecly moved nally pen the wrench shank until erly spaced from the fixed jaw wherehy the out or i eatmay he ngined hetwi. n t lid jaws, Whe ere-"sure upon is rt cased. id springs immediat I rn to their normal condition draw 1 "ec ends of the dogs inwardly into engagement with the teeth 8. thereby preventing a further inward movement of the adjustable jaw. In this manner. it will he apparcm that the jaw 9 can he very Iv and quickly adjusted upon the wrench shank and will he securely held in its adjusted position. thereon to resist any longitudinal prt sures or strains to which said jaw will he subjected in ordinary use.

it is apparent that the device as a is exceedingly durable in construction and, ashnt few parts are employed which dogs in engagement with the l ole are all of simple form, the wrench can be manufactured at comparatively small cost. The device can, of course, be constructed in various sizes and the wrench aws formed in any desired shape.

While I have shown and described the Letters Patent is 1. In a wrench, the combination of a shank having a fixed jaw on one end and spaced teeth on the opposite faces of the shank, a longitudinally adjustable jaw engaged upon said shank, pivoted pawls carried by said adjustable jaw, and a bowed leaf spring fixed at its extremities to said pawls intermediate of their ends and nor mally holding the free ends of the pawls in engagement with the teeth on the respective faces of the wrench shank, pressure upon the medial portion of the spring acting to force the free ends of the dogs outwardly anddisengage the same from said teeth preferred construction and arrangement of" whereby the adjustable jaw may be shifted upon the shank with respect to the stationaw jaw.

2,111 wrench, the CDInbiIliltiOIl of a shank hail ng a fixed jaw 11 one end and teeth upon-the opposite faces of said shank, an adjustable j aw mounted upon the shank and .having a tubular body portion through which the shank is disposed, dogs pixotally mounted in the inner end of the adjustable jaw body bowed leaf springs fixed at their extremities to the corresponding edges of said dogs intermediate of. their ends and normally holding the free ends of the dogs in engagement with the teeth on the opposite faces of the shank, said springs extending across the untoothed faces of the shank and having their medial portions spaced therefrom, said springs being adapted to be pressed inwardly toward the shank whereby the free ends of the dogs are forced outwardly and disengaged from the teeth on the wrench shank to permit of a longitudinal adjustment of said adjustable aw.

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