To all whom it an ay concern l Be it known that I, TILBUR S. Urso s a CltlZGIl Ojl i the United States of hmerioa,
lid
, plish the above residing'at ljlanstield, in the county oi Riehland and State of Qhio, have invented oer-j tam new and useful Improvements in "Wrenches, of which the tollowingis a s eel iioatiotou ,7 j v i v -';llns invention relates 'to wrenches, the jaws of which are adapted to be quickly andeonveniently adjusted to engage vari (his sizes of nuts, bolts, and'the like and whiehare also operable to engage the nuts,- bolts andthe, like through the 111C dum of the usual serewieedb The primary toot this invouti on is to, provide a 'wrenoh with a stationary aw and a cooperating nuwable jaw,the movable jaw/of which is adapted tobe freely, oxpeditely, eiiieiently and rapidly adjusted toengage different sizes of n'uts bolts and the like by instantly disengaging the actuating" means from the .movable will otthe o1'3 erato1.',o1. if desired the actuating means can be operated to feed the "movable jaw'to engage Various sizes of nuts, bolts and the like in the Conventional man nor. v
The preferable specific means to aeeonr described objects in brief oomprise a worm nut pawl mounted upon a piyoted shaft and which is normally held in yielding engagement or mesh with a worm cog rack formed on the movable jaw.
'. These the mechanism illustrated in the accompanying drawing, in which:
Figure l is a side elevation partly in sect-ionol a wrenehhaving the invention applied thereto, showing the worm nut en aged, or in mesh with the worm cograck of the movable jaw.
Fig. 2 shows a section of the wrench on the line :0 a; of Fig. l.
Fig. 3 is a side elevation of the wrench showing the worm nut ment with the worm cog rack otthe movable jaw. a I j In the drawings reierence numeral 1 repi t 2 Q pressing downward of the stationary jaw,
resents the shank the movable aw.
the stationary jaw and 3 The movable aw is provided with a shoe I l haying a worm cog rack-5 formed thereon.
The shoe slidably engages theguideway 6 :tormed in the body portion .7 of'the sta- "ionarviaw;

If the adjustment is slight, theoperator it he prefers to do so can rotate the Worm nu-t pawl to actuate the movable jaw for adjustment in the usual manner." I t Attention is calledto the fact that the movable-jaw eanalso be 'adjustedyvithout on the worm nut pawl by pressing agam'st the movablejaw withthe thumb t'oward the stationary aw, JA v .110 a'pr'essure. upon the spindle, p'er-' tention is called to the fact that the spring,
in exerting y dms r.
forces the worm cog-screw into mesh with the cog teeth; it forces and keeps the worm cog-screw and cog teeth constantly in frictional contact with each other, to thereby prevent the cog screw from turning through accidental contact to change the adjustment of the movable jaw; and it automatically takes up the wear of the'parts.
I claim: 1. In a side jaw wrench, a handle made integral with a stationary jaw and anin-termediate enlarged portion, said enlarged portion having a guideway formed therein in angular relation with respect to the handle and also having formed therein an intersecting' angularly related aperture, a pin secured in the enlarged portion of the wrench, a spindle pivotally secured to said pin and adapted to extend across said intersecting aperture and to be moved to and from said guideway, a worm screw mounted upon said spindle, a movable jaw slidably mounted in said guideway and having a shoe thereon with a series of cog teeth, and yielding means adapted to normally maintain said worm screw in mesh with said cog teeth, but adapted to be Withdrawn therefrom at the will of the operator, said last-mentioned means also performing the function of preventing the Worm screw from turning undernormal conditions because of the frictional yielding contact maintained between the Parts y Said y in means and auto cally taking up the wear thereof.
2. In a side aw Wrench, ah'andlefmade integral with a stationary jaw and an enlarged portion, a guideway formed integral in the enlarged portion in angular relation with respect to the handle which intersects an aperture formed insaid enlarged portion and which is angularly related thereto, a pin secured to the Wrench, a spindle pivotally secured to said pin in such. a manner as to extend across the aperture and which is adapted to be moved to and from said guide- Way, a worm screw mounted on said spindle,
a jawslidably mounted in said guideway' carrying a shoe having a series of cog teeth formed thereon and extending into said 1ntersecting aperture, and yielding means adapted to normally maintain said cog worm WILBUR- S. UPSON.-
