WRENCH.

APPLICATION FILED APR. 2, 1914',

Patented Sept. 8, 1914".,

wiffnem Fltboz new Tooll 'whom it may 'fuman WALTER. or' woonnaNn; oaLrronNIa. f;

Beit known that I, LAND'R XVfLIrLLsAP, a citizen of the United States, anda resident of Woodland, in the county of Yolo and State of- California, have invented anewr and vuseful Improvement in Wrenches, ofA

which the following is a specification.

. This Vinvention relates to wrenches, and vone of the principal objectsftheof isthe provision of a wrench having an adjusting screw, whereby the Wrench may be loosely adjusted upon a nut, 'and having a locking lever whereby after looseadjustment of the and locking-handle, and having means for' wrench the jaws thereof, may be tightly'- .forced against thenttofprevent slipping ofthe wrench.4

` Another; object of the invention to pro- 'videa wrench having a locking handle, and

-lneans for maintaining the 'handle inv anyV 'adjusted position.- f Y i A furtherlobjectof the invention 1s to provide 'a wrench having an adjusting screw,

Iin'nxintaining the handle in any looked vposition, and means for releasing at' will the i locking means.

" a vertical transverse sectional view 'taken Still another object of the invention is to provide a wrench of the'lass described,

`which will.be extremely simple, dnrable,-

efficientI in operation and inexpensive-to `manufacture. f

With these and other objects in view which will become apparent as the descriptionr proceeds, thel invention resides -in the construction, combination and arra'ligement` 'of parts herein-after more fully described and claixned,.and illustrated in theaecomlpanyingr drawings in which likecharacterls' of reference lndicatenllke parts tlnoughouty the several figures, of which- Figure 1, represents a side elevational view o f the wrench,. a nd, -Fig. 2 represents on 'theplane-indicated by the linel 2-A-'2 of `ig. 1, looking inthe direction of 'the arrows. Y Referring more`V particularly to the drawing, 5 indicates a wrench handle, having formed'at oneend thereof a fixed jaw and Yat 7 is indicated the movable wrench .jaw slidable toward and away from jaw 6, and the jaw 7 may beloosely adjusted tolit various'size nuts` by'means of the worm' 8' ro-4 tatably mounted on the -pin 9, which at its upper end extends into a recess 10 formed 1n he handle to the rearof thelixed jaw (i,

Theworm is placed in a rectangular opening 12 formed in the handle, and is disposed., axially at an inclination with the handle land parallel withthe lineof movement oi the movable jaw. The worm may rotate on pin 9 but is not Vmovable longitudinally thereof.

"The lever is` pivoted by meansfof a rivetor pin t8 to. thehandlej adjacent the pivot point'- V17, and thedcver 15 extends rearleverngef imoirrja\\" 7 may be obtained `by operating lever l5'.

In operation, the movable jaw is loosely 8 and the leverl is then brought into play, to lock the jaw against the nut, and by means of the rack bar and detent described, the lever will be maintained in any adjusted'position so that there willlbe nofdanger of the wrench accidentally loosening from Y the nut. When the work is finished the button 25 may be pushed forwardlyfreleasing' theI detent from the rackbar, and the action of spring 11 will be to slightly force -the jaw away from the nut so that the wrench may be instantaneously removed.'-

It has been found that a wrench constructed according to my invention, is4 especially adapted for use on battered nuts, and that when the jaw has been locked in position a fixed jaw at one end t by means of the lever, the wrenchV may be whirled around without danger of loss for releasingthe nut. A great advantage accrujaw', a worm for-adjusting the movable jaw,

a pin on which said worm is journaled, said pm at one end -extendlng into a recess'in' l the handle, a spring insaid recess bearing against thepin and adapted to' maintain the jawand worm at the outer end of their movement, a lever having its forward end bent downwardly, said lever at its forwardly bent end extending through an opening in said handle, said lever having its extreme front end slightly off-set and pivoted tothe lower end of said pin, said lever near, last said pivot point being pivoted to the wrench, a rack bar pivoted to the handle of the :levernear the rear end thereof, and depending Aalongside said wrench handle, a dog pivoted to the wrench handle and adapted' -to normally yengage said rack bar, a link pivoted 4to said dog, a button adjustable longitudinally of the handle, said link extending through said button at its forward end, .and springsfor normally maintaining said rack bar 4and dev tent in position to engage each other.

2. A wrench comprising a handle having ,a fixed jaw secured thereon, a movable jaw, a pin, a worm thereon whereby said movable jaw may be adjusted, a spring bearing against said pin for normally holding said .worm and movable jaw at the outer extreme of their movement, a lever pivoted to said handle, said pin. ivoted at its lower end to said lever, a racii bar carried by the lever, a detent carried by the wrench handle and adapted to normally engage said rack bar, and means forpmoving said detent out of engagement with said rack bar., Y i

3. A wrench comprising a handle having a fixed iaw formed at one end thereof, a movable jaw, means for loosely adjusting said movable jaw,A a lever. pivoted to the handle, said lever being connected to said jaw adjusting means, means for normally holding said movable jaw at the outer ei:- treme of its movement, a rack bar pivoted to the lever handle, a dog pivoted to the wrench-handle andadapted to engage the rack bar, a link connected to the do and means for opera ting the link at will or releasing the dog.
