Be l it known that I, 'Lunvre` `a subject of thevling LofSfWeden, DearyLin the county o f` Latah and State/of Idaho, have invented certain use f provements l/Vrenches, l of. which `rt lowing is aspecification,A reference be therein to the accompanying .drawing,..i`

1` This invention relates toimprovementsiin wrenches, one object of the invention being the4 provision. of a `quick acting Wrench `pro-1 vided With means for controllingonelfofthe and by means` of Whichfwhen the;` handle 1s operated` upon in-lone `clreetiomithe` nut will be firmly gripped betvveenjthejaws,

and When operatedin `the Vopposite direction, the jaws will be permitted,tofrelease the nut to permit of the easy insel-tiener Withdrawal of thelvvrench, yet bycontinuing l a y pressure 1n the Vsame direction-.thenuft `vvill dotted' positions illustrating lthe action Aof l themembers in producing a clamping; action between the jaws. i y V- `Fig. 3 is a sectional; view taken online 3-3of Fig. 1. y l Eig., 4L is a section taken onflineifi-li of Fig. 5 is a section taken on line 5`5 4of Fig. 3.

the handlevofthewrench may assume `the fullfand dotted .line positions, `as shown in Fig. 2.`

In `order to holdl the `jaw "19 `to i;

the "body 12 and yet permit the jaw -19 to bemoved a` relativeHdistancelto `and `from the j aw 18' into nut engaging and releasing position, aV radius plate 214;. is pivotally l.connected by the screw 25 tothe jaw 19, While `it `is slidingly connected throught,` the l slot y 26 `and the screw tothe bodyf`12.t` t

"Thus,` with the point. 2555,` as shown in Fig.` 2,th`e centerof `theeircle described by thevvall 15@ and the Washer22, the respective corners 29 `and Opf the body 121Wfill engage' the corresponding portions ofthe j avvr 19 andcause the same to assume the positions as` shown in Fig.l 2.`

i Irwin be understood that Byv continuing the pressure on the handle itmay likewise be moved in areverse direction so that the oppositel end of the body portion Will engage the. corresponding inner vvorkingpos'ition and by reason of this relation of parts it will be appreciated that'it isj'unneces'sary tol remove thejayvs'from about then'ut (not shown) to againposition them `inI an operative position. It is tobe appre- V v cia'tedithat the swinging' movementispermitted by the plate having a slot therein i which is operably arranged about thescrew 27 lonthe body portion'. i
