` any nut and have a tendency to turn or .mar

the corners or crush orotherwise disfgnre the fixusli asy when melrel plating or japan coating is used. The acljustahle wrenches,

pliers and tongs are slow'iaeperation, do f not grip and` hold the nut rods, or pipes promptly and efficiently` and tendto'work open in operation, makingit necessary to repeatedly adjust'thexn tothe work;` with the exception of a few Wrenches of the ratchet`type which have but lil'nitedapplin iati'on and but narrow range of utility, all wrenches known to me require to -be withdrawn from the workjand a new grip `found. Y afterw moving' the `Work a small distance. Pipe wrenches generalhm including the fzltillson7 type, eanheladjusted hul'4slowly and inasmuch astheir engagement with the pipe is effected Aby a cutting in of their grippmgsurfaees they tend tomar the finish and Atoflatten or` crush thepipe, especially pipef of'light weight;-tl1e plier types of `wrenehes are` used at a disadvantage in that when the kjaws are widely seiparated the handles are simliltane' uslyl widely separated rendering "them awl varlil in use and difficult to effec-A tively grasp. lflther l(lisaflvantagres of the wrenches `jivaislahle atfthi's day are known to those who are skilled in the art aand need not to he further dwelt upon. l "Tn miei-Corning -the stated and other ohjeetions and. disadvantages, anclin. gaining the objects aloove mentioned.' as well as certain further benefits and advantages to he' below pointed out, l haveprovtled the conf de elevational view illus struetions illustrated in the accompanying 4 vention iny the form of a. monkey wrench;

he ,seen that for purposes of" illustration'l have hereshown a wrench emy .hoilying'my improvements, whirh is useful 1f.) ratchet teeth as indicated at 16.

for the purposes for whichv the ordinary monkey wrench is commonly used, but'is adapted toserve such purposes in a better manner. On inspection ot' Fig. 1 more pargroo/ved as indicated at 13 to receive the.

tieularly it will be observed that I provide a shank having at-one end a handle 11 and.

at theo'ther end a jaw 1.2. The shank- `10`is shank 14 of the opposing jaw 15 which is slidably mounted therein and provided with' For holding the jaws 12 and '15 in predetermined pof as indicatedvat 22, adapted to engagev with the ratchet teeth 16. For normally holding sitlon I employ a bifurcated lever 17,-pi voted to the shank 10, as indicated at 18, and enavin b means of'a )in 19 the slot 20 in a, g n g l sliding b ck S21 provided with ratchet y,teeth the members 14and 21 in contact, and in engagement by means of the teeth 16 and '22. I employ a sliding yoke 23 slotted on each side, as at 24 and 25, for engagement with th'e projecting Aends ofthe pins 26 and 27. 27*

respectively carried bythe .shank 10 and the block 21. To hold the yoke23 in 'adjusted' position I provide thereon a spring 28 provided Witlr a projecting portion 38 adapted to engage notches 30 formed in the shank' 10 and in providing means :tor holding the toothed portion22 ofthe,blo`ck 2l in en-r gagement with the toothed lportion 16 of the shank 14 I employ a spring'Bl riveted to the.

yoke 23 Aat 32 and havinga downward projection 34 passing through an aperture 35 in such yoke and bearing upon the face 36. ot` .such-sliding block21. For locking the memfreely relatively to the shank 10 I cnt away the said shank 14,' as indicated at41, and insert therein a spring l42 bearing on the bottom 43v of the said shank 10. In the operation of the'wrench above described itwill be understood that when theyoke 23 1s moved outward as far as the slots 25 will permit,

the pins 27`and'27 .hold it'in .the depressed position shown so as to prevent,k the toothed faces/16 and 22 from disengagement and thereby thejaws 12 and '15; from rela 'tive longitudinal movement. Likewise that when the yoke is moved inwardlya short distance the pins 27, 27 will torce it upward sufficiently to allow the teeth -16 and 22 `'to passeach other,b'ut.the spring 31 will continue to press upon the face -36 of the'block 21 suliciently tomaintain engagement'and prevent movement of such blockto inward. though permitting the .movement thereof outward since the ratchet teeth 22 tend lto,

above explained.

` and 15a having suitable l curved and toothed;

slide over the teeth, 16; Furthermore that" whenthe yoke 23 is'moyed farthest inward, the block 21 is raised suflicientlyto entirely disengage the teeth 1G an'd 22, and permit movement of the-block 21 in either' direction. Similarly that by virtue of the extension 88 of the'spring 28, striking the pawl 37,' such pawl is thrown out ofenga'gement with the toothed portion 39 of the vlever 17. From the foregoing description it will be observed that in the use offa wrench embodying my'. invention in the form above described, the yoke 23 is drawn farthest inward, allowing theready disengagement ofthe members 21 and 14, and thus relativemovement ofthe jaws 12`and 1 5 which arethen set at as close as possible an approximation ofthe correct .distance apart, the handles being then first arranged in a convenient position for operation,. and afterward slightly opened. The yoke 23 is-thereupon moved outward andthe handles l1 `and 44 of the' 'sliarilnl10 and the .lever 17 arebroughttogether as'far as may be necessary to hold thenut or other object engagech It will likewise be observed that inasmuch as the pivot p in 18 is fixed andthe pivot 19 movable to the left 'in the approximation of the-handles 11 and 44, thus mov ing the jaw 15 toward the jaw 12, any pres sure tending to draw the handles togetheris proportionately transmitted to the jaw l5 and thus that the greater ,the' presslire/jeta'-` erted -upony the' handle 44 in the operatic ot the device', the greater the pressure ex ted upon the nut or other' object engaged.

)[oreover, h when the yoke. 23 is in the position shown mere separation of the handles 1l and `44 opens th'e jaws suliciently to changethe hold, or if desired, gain ahold at a different angle, without removing the 105 `Jaws from the work.- In vork1ng onirregularly shaped objects by` moving the sleeve until'the pins occupy positionsl relatively to .I

the slots indicated'at 2G' andf27the jaws may be opened wider by' virtue v'of .the ratchet action between the lteeth'l and 22 As is'- clearly to be seenon reference to Fig. 1. by virtue of the disposition of "cutting"v edges 45 and 4 6 lon the jaws v1 2 and 15 the device above rdescribed maybe lfadily'used asaw'ire cutter.

#Referring noir' more paiticularly to the device of Fig'. 5 on inspection ofthis ligure it will be noted 1thatbyl providing jaws 12 engaging surfaces, indicated'at 41,48 andv 49v and 5Q, re"spec tively,'the surfacesd? 'and 48 beingjiii. juXta-fposition buti of .different radii, in' the wrench 'construction above .defl'r scribed an improved wrench is pro-i vided, Which is advantageous in thatit may be opened, quickly-arranged about the pipe,
