JAMES E, OWEN, or EDGELEY; nontrnvnaxomay 1 WRENC To all 2071 am it may conoem: e Be itknown that 1, JAMES E. OWEN, a subject of the King of Norway, residing-at Edgeley, in the county of Lamoure, St'ate. of North Dakota, haveinv'ented certain new and useful Improvements in WVrenches, of which the following is adescription, reference being had to the accompanying drawa provide a wrench with two aws having free ingand to the figures of reference marked thereon. a j e 3 This invention relates tohand wrenches.

One of the objects of this invention isto relative adjustment; said jawsalso having means for forcingthem into gripping contact with the object all positions of adjustment. v

A further obj ect of the invention is to provide a" wrench including two jaws having freerelative movement into all positions of adjustment, said jaws also having cooperative means for forcing the same together to more firmly grip the work. a

A further object of the invention is to provide a wrench including two jaws having free relative movements into all positions of adjustment," together with interengaging means connected to said jaws for forcing the same together, at least one of said means being adjustable whereby said means will interengage in all positions of adjustment of the jaws.

A further object of the invention is to provide a wrench as above described in which the freely movable jaw is provided with means pivoted thereto and adapted to engage a portion of the stationary jaw for producing a gripping action between the aws. j v j e These and other objects will in part be obvious and will in part be hereinafter more fully disclosed. l a I I In the. accompanyingdrawings I Figure 1 represents a perspective view of the wrench; and i j j a V Fig." 2 is a sectional view of'the wrench showingv the handleconnected to the mov able jaw disengagedfrom the shank portion of the fixed jaw.

handle.

in "the form of ahandle' pivoted thereto so that it may be swung intocontactwithl'anl extension of the shank, and such shank and handle have interengaging means adapted to ,forc'esaid jaws together to create a grip ping action therebetween. Inorder'to pro vide for this gripping action totake place inall positions of adjustment of the movable jaw, the connection between the latter and its handle is made adjustable.

Referring more particularly to the acconi-- panying drawings; the wrench comprises a fixed jaw, ljprovided with an integral shank 2hav1ng an eatension 3 in the form of a At any suitable place therealong, Z

thisfextension 3"is formed with a preferably integral upwardly extending lug or cam '4; hereinafter more specifically referred to; A movable jaw 5 is freelyfslidable'on the shank portion 2 of the fixed jaw 1 and is freely adjustable therealong into all ost tions of adjustment to engage the'object be-- a tween thesejaws. The jaws are provided action on the object held therebetween'in all positions of adjustment of the jaws, and to this end there is provided a handle 6 hav-' tented-fMay-lfl; 1921.

"with means for producing a firm gripping ing an extensible pivotal connection with the movable jaw 5. One form of connection is shown in the drawings in which the hana idle 6 is provided with a threaded bore 7 j e j prvoted at 9 between two 11 standing ears 10 integral with the jaw 5.

adapted to receive a threadedbolt 8 n order to accomplish this inward forcing of the movable jaw toward the fixed jaw, the handles 6 and means which are adapted to engage asthe handle is brought toward the extension 3 of extension 3' are provided with cooperating I the shankQ. One'means for accomplishing f this comprises the before mentionedlug or earn 4: which is provided with an inclined facellpreferably terminating ina face 12 perpendicular to the shank 3; 7 It is of course obvious [that theinclined face 11 may be continuous, or that these faces 11andi12 used to produce thev desired result. Cooperating with this cam face, the handle 6 is ingly inclinedinner face 14 adapted to en ,v gagethe incline 11 on the cam 4. It is of course obvious thatthere are many other I spect to the fixed jaw 1.

ways of producing this inward forcing action of the freely movable jaw with re- 1 In operating the jaws as above described, the handle is lifted into position as shown I Fig. 2 and'the movable jaw 5 slid along the shank Zuntil it makes contact with the object, heldfltherebetween; .The handle 6 is now adjusted withrespe'ct to thebolt' 8 so thatthe inner-face 14 of, the cam slot l3 r re'gisters in its lowered position with the inclined faCellofthe cam 4. The handle 6 isnowfforced' downwardly toward theextension 3 therebyjpermitting the cam 4 tov enter thehslot andby the action of the cam v faces forcing the jaw 5 into gripping contact 'It is'of course apparent that a device of this nature isvery desirable, particularly in cases wherea wrench has tobe used on an object ofuniform size, inasmuch as the release of thehandle never disturbsthe adjustment of the jaws, so that the next time it is used, itis only necessary to'slide the. movable jaw 5into position and grip the handle and extension 3 together as in the ordinary use of a wrench.

It is obviousfthat 11111101" changes in the detailsjof construction maybe made without departing from thespirit of the invention as set forth'i'n the appended claims.

Having thus described the invention, what I claim as new and desire to secure by Letters-Patent, is v '1. A wrench comprising a stationary jaw having alshank and an extension, a second nected solely to said second jaw and means on said extensions for producing a grip 'pingfaction' between said jaws while said extensions are forced together.

2. A wrench comprising relatively mov able jaws, each having anextension, one of said extensions being pivotally, connected to one of said jaws and swingablebodilyvtoward said other'extension, means adapted to" cause a; gripping action between said jaws when 331d, extenslons are. forced together,

and means for producing an adjustment of.

one of said extensions relatively to its jaw. 3. A wrench comprlslng a aw having an extension, a second jaw 's'lldable on said first jaw, a threadedmember"pivotally connected to said slidable jaw, a second 'exjaw movable on said shank and provided with an adjustable extension pivotally contension adj ustably threaded on saidmernber, and cam means intermediate said extensions s when said extensions are
