' To all whom may concern:

bined pliers and wrench, thedevice being equipped with novel. means for making adustment in the size of the jaw opening for facilitatin engagement upon articles or objects oi diherent sizes. 1

An important object is the provision of a tool of this character which will be simple and inexpensive in manufacture, highly eficient in use, easy to adjust, durable and practical in service, and a general improvement in the art, With the above and other objects and advantages in view the invention consists in the details of construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which:

Figure 1 is an elevation of the showing it in closed position,

Figure Q is a similar View showing it in open position,

Figure 3 is a similar view with various parts in section to illustrate the connection and showin the adjustment feature for re%ulating the size of the jaw opening,

igure 4t is a detail cross section on the device line ll of Figure 1,

Figure 5 is a detail cross section on the line 5-5 of Figure 1,

Figure 6 is an edge elevation.

Referring more particularly to the drawings the numeral 10' designates a relatively stationary handle which terminates at one end in. a curved relatively fined jaw 11 which has its active face curved and formed with teeth 12. The other end of the handle 10 termniates in a reduced threaded ertension 13 upon which is screwed a nut 1d for a purpose to be described The numeral 15 represents the relatively movable jaw which co-operates with the jaw 11 and which likewise has its inner ace preferably. curved and toothed as indicated at 16. This java member 15 is bifurcated to define arms 17 which straddle the handle member 10 and which are pivoted therer the operator out that the jaw 15 will be to as shown at 18 by means of a bolt, rivet, pin or the like;

The relatively movable handle is designated by the numeral 19 and has one end tltting within the bifurcation in the jaw menaber 15 and pivoted by a pin, or rivet 20. ()n the intermediate portion of this handle 19 is a projection or lug 21 which is adapted to engage against the handle member 16 intermediate the ends thereof whereby to form a stop. The numeral 22 represents a link which has one end "torked and straddling the lug 21, pivotal connection being efi'ected by means of a pin or rivet 23. The other end of this link has its lace toward the handle 10 concaved as indicated at 2% and pivotally carried by the extremity is a small yolre 25 which embraces the threaded extension 13 for adjustment purposes to be described a v While it is not obviously essential we prefor to employ a spring 26 which is of the leaf type and which is riveted or otherwise secured onto the member 10 as shown at 27, its free end bearing against the relatively movable handle lt for the purpose of urging it normally in one direction so that when the device is used as pliers it will automatically adjust itself.

The open position of the tool is shown in Figure 2 and it will beqohserved that in this position "the jaws are open and the handle 19 is away from the handle 10. To use the device as pliers, the jaws 11 and are engaged upon thearticle or objects while holds the handles 10 and 19 within one hand. When the handles are subsequently squeezed together, it is appar swung upon its relation with the ivot 18 into clampin eClllVG grip may be aw 11 so that an e had upon whatever is to be turned. size of the opening of the jaws is regulated by the position of the nut is upon the threaded extension 13 as is clearly shown, it being notable that the yoke 25 may be engaged between any two selected threads for maintaining the adjustment. For oi:- ample when the nut l l is run out to near the end of the threaded extension and the yoke 25 engages the extension near the nut, the device is capable of engaging articles of larger size then when the reverse is true and the jaws 11 and 15 will not come together even though the handle 19 bepressed to its maximum degree toward the handle The said fixed jaw and 10. For gripping small articles, the yoke 25 must be located nearer the juncture of the extension 13 with the end of the handle and the nut 14 must be run up or in on theextension.

When us ng the device as a wrench, it is 0t necessary to move the handle 19, the ad-' justment of the size of the opening between the jaws being regulated merely by turning the nut 15. In this instance, as the nut bears against the end of the link 22 the handle 19 and jaw carried thereby will be moved to effect the adjustment.

From the foregoing description and a study of the drawings it-will be apparent that we have thus provided a simply constructed and consequently inexpensive tool which will be highly etficient for the purpose specified and plicity is not likely to get out of order so that a long life should be assured.

ile we have shown and described the preferred embodiment of the invention it is of course to be understood that we reserve the right to make such changes in the form, construction and. arrangement of parts as will not depart from the spirit of the invention-or the scope of the subjoined claims.

Having thus described our invention we claim:

' 1. A'tool of the character described comprising a relatively stationary handle terminating at one end in a fixed jaw, a curved relatively movable jaw co-operating with terminating in arms and pivoted upon said handle straddlin first named jaw, a relatively movnear the able handle pivotally connected with the inportion of said movable jaw, a link pivotally connected at one end with the termediate intermediate able handle, able on the j which the other end of said link engages.

2. A tool of the'character described comportion of, the relatively movand an abutment member mov- .prising a relatively stationary handle termi which on account of its Sinkfirst named handle and against at one end in a fixed jaw, a curved movable jaw co-operating with said fixed jaw and terminating in arms straddling and pivoted upon said, handle near the first named jaw, a relatively movable handle pivotally connected with the intermediate portion of said movable jaw, a link pivotally connected at one end with the intermediate portion of the relatively movable handle, and an abutment member movable on the first named handle and against which the other end of said link engages, said relatively movable handle being formed intermediate its ends on its face toward the first named handle with a lug engageable therewith whereby to limit the movement.

3. A tool of the character described comprising an elongated relatively stationary handle terminating at one end in a fixed jaw and having its other end formed with a reduced threaded extension carrying a nut, a relativel movable jaw of bifurcated formation stra dling and pivoted upon said relatively stationary handle near the fixed jaw thereon, an elongated relatively movable handle pivoted within the bifurcation of the relatively movable jaw at the intermediate portion thereof, a leaf'spring carried by the relatively'stationary handle extending within the bifurcation of the movable jaw and engaging the pivoted end of said relatively movable handle, the intermediate portion of the relatively movable handle being formed with a lateral extension projecting toward the relatively stationary handle to serve as a stop, a yoke straddling and pivoted upon said extension and having a heel adapted to engage upon said nut, and a loop carried by the free end of the yoke adjacent the heel and embracingly engaged about said threaded end.

In testimony tures.
