Specification of lietters Patent.

Application filed December 12, 1910. Serial No, 596,801.

To all whom it may concern Be it known that I, 'WILIJIAM Bowman, a citizenof the UnitedStates, residing at Mo- Henry in the countyIof'Harrison and State of Mi sissippi,- have "invented a new and useful Wrench, of the following is a specification.

I It is the objecti of'this inventionto pro-- may be held. by 'nov justed positions wit respect *to the; fixed Another object oitlthe-infi'ention is to projaw, of novel 'and' improved means vforadjustable connection with the handle of the'wrench, i a

In the drawings, Figure '1 .;is-'a'side elevation showing the movable'jaw locked in tionshowing the movable jawtiltably united with the handle of thewrench', and in the position which it will assume while gripthe invention shownin Fig. 2 being modified slightly from: the showing of Fig. 1 ;"-Fig. 3 is atransverse;v

' the handle 3, this thumb. screw 19being denoted .by ithe numeral 3, the handle being supplied place upon the handle of the .wrench, parts being broken away; Fig. 2 is a. side elevaping an article; the form of section upon the line 3 3 of Fig. 1.

The handle ofthewr'ehch is with an angularl'y disposed fixed aw.1,-havin'g teeth 2 upon its inner face. A movable jaw 6 is slidable upon the handle 3, so as to coiiperatewith the fixed jaw 1, the end 9 of the movable'jaw G being provided. with teeth'10,'c06perating wlth the teeth 2 of the Speakin generally, the movable jaw ,G'lS

nected by ahead 15,. The handle 3 is disposed between the arms 11, the head 15 bemg disposed upon one side of the handle -3-and a filler 12 being disposed between the arms 11 upon the other side ofthe handle The invention further includes a nose 5,

supplied with a shank 8, adapted to register 11118. recess 7 in oneend of the filler 12, the nose 5, being held-inplac'e upon the filler 12 'in' any desired manner: The nose 5 is adapted toengage with teeth 4 formed in The nose is one edge of the handle 3.

v whereupon the mov filler 12 and 1 replaced by anothernose when worn or'injured. The edge of the .filler'1-2 which. is disposed toward the handle. 3 is concaved, as'at 14, thus, reducing the sliding friction between the movable aw 6 and the handle 3.

Positionedbetween' the handle 3 andthe head 15 of the movable jaw, is a spring plate .17 secured at one "end to the head 15. by means of a, bolt 1.6 oriother fastening device. Adjacent i tsrfreenend the spring 1? is curved, 'asfllshown at '18, to bear against acts to maintain the'no'se in engagement with the teeth 4, the movablejaw 6, how.- ever, being .tiltable upon the to withdraw the nose 5 fromithe teeth of the Patented Jan. 9,1912.

handle 3' so as The spring 17 an outstandinglug 21, theface'of which is serrated as shownatq22. --The thumb or finger of the operator may be placed upon'this.

serrated lug in order totilt the movable jaw.

The invention-further includes a movablemember, preferably a "thumb screw 19,- threaded throughthe' head "15 of the movable jaw, and adapted'toengage one edge of equipped with a locking device, preferably;

lock nut 20, whereby the thumb screw may, be held against rotation in the movable jaw.

,In the -modified form of thejinvention' shown in Fig. 2, the movable jaw 60 isequipped with afiller 120, the 'nose 50 being formed integrally with thelfill'e'r, instead of being removable therefrom, as in Fig. 1.

When the thumb br finger of the operator is placed upon the'lug 21, the movable "aw6 may he slid transversely withdrawing the nose 5 longitudinallyof the handle '3,- into adjusted spring17, enga mg the handle 3', will bring the nose 5 in engagement with the teeth 4.-

When the wrench is appliedto an article, to rotate the same the movable jaw 6 will tilt slightly,

of the ban from the teeth 4," table jaw may he slid POSltlOIlS with respect ththe fixed jaw 1.." When the mogahle 'jfaw is released, the] as shown in Fig. 2, the nose,

When it is desired-tohold the movable jaw in fixedwelation with respect to the other jaw'of the wrench, the thumb screw 19 may be rotated as shown in Fig. 1, the

thumb screw engaging the shank 3 afid binding the movable jam 6 firmly upon the handle of the wrench, the lock nut 20 being rotated until itengages the movable jaw.

Referring to Figs. 1 and 2, it will be seen that the teeth 4 of the handle 3 terminate at such a distance from the fixed jaw 1, that when the element 5 in the one instance, and the element 50 in the other instance, are engaged with the teeth 4, the opposite end of the filler will bear upon a plane surface'in the handle 3, located between the teeth 4 and the fixed jaw 1.

What I claim is:

A wrench comprising. a handleprovided with a fixed jaw; a movable jaw including an arched member inclosing the handle slidably, and a filler held within the arched member, that" edge of the filler which is adjacent the handle being concaved, whereby the filler will bear against the handle adjacent the ends of-the filler only; there being teeth in thehandle, adapted to be engaged by one end of the filler only, the teeth terminating at such a distance from the -fixed jaw, that when one end of the filler is engaged with any of the teeth, the other end of the filler will bear upon a plane portion of the handle lying between the fixed jaw and the teeth; there being a spring in the movable jaw, normally holding both ends of the filler in engagement with the respective parts of the handle; a movable member in the. movable jaw, independent of the spring, and adapted to engage the handle-to hold ,both ends of the filler against the handle; and means for holding the movable member in a handle-engaging position.

Initestimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two wltnesses.
