, the; features wrench and an ad ustable plpe wrench, a



To all 10.1mm it may concern .1

Be it known that I, JAMES VVILLIAM TRAoY,,a citizen ofv the Un ted States of America, residing at Smithland, in the coui1ty;,of 1 Livingston and State of Kentucky, have invented. new and useful Improvements in Wrenches, of which the followingis a specification. P I The object of the inventionis to provide a device which will possess in combination of an adjustable monkey pail-1x of pliers and wire cutters.

A further object of the invention is to provide a device of this kind which is simplein construction,durable and effective in operation and-inexpensive tomanufacture.

- Other and further objects appear in the following description wherein theinvention is set forth in detail.-

To the exact construction in which it is shown and described, the invention is not to be restricted. The right is reserved to make such changes or alterations as the actual reduction to practice may suggest, in so far as such changes or alterations are compatible in spirit with the annexed claim.

The same numerals of reference designate the same parts throughout the drawing, wherein:

Figure 1 is a view partly'in section and partly in elevation of the improved wrench.

Fig. 2 is a side 'elevational view, the han dles being omitted.

Fig. 3 is an edge elevational view of the structure in Fig. 2.

Fig. 4 is a detail perspective view of one of the elements comprised in the active or movable jaw of the device. 7

As shown, the invention embodies what might be termed a passive jaw 1 and an active jaw 2. The jaw 1 is carried at the upper end of a bar 3 which is preferably rectangular in cross section and which is preferably formed integral with the jaw, this bar 3 also being formed integral with a disk element 4 which connects with the bar at the endremote from the jaw 1 and which has connected to it the handle 5, the

latter connecting with the disk element at a point diametrically opposite the point of connection with the bar therewith. I

A second handle 6 is embodied in th structure of the tool and this handle 6 is formed integral with a disk portion 7 of Specification of Letters I-atent.

. similar shape to theidiskportion 4 and the two handles, are-pivotally connected to gether; bymeans of apin or rivet 8 which passes centrally through them, thus holding them securely together; On diametrically opposlte pointsontheir edges, the/two disks and? are formed with the recesses 9 which register 1n" certain positionsof the handle and are thrown out ofregistration in other positions .ofthe handle. Obviously a piece of wire placed in eitherfofthe notches when the two recesses of thetwo disks are. in registration will be severed when the notches are thrown out of'registration on the movement of the handles 5 and 6 toward each other.

I Patented Aug; 1a, 1921. I m ly-21, 1919. Serial No. 312,3 56. 'i

:The disk 7:at a point diametrically opposite the point of connectionwith the handle 6 1s providedwlth an arm 10 in the upper edge of which is formeda slot 11, of the shape .indicatedin Fig.1 of the drawing.

In thisslotfthere-is pocketed one end of a The block 15 may thus slide longitudinally along the bar 3 and such a movement will be lmparted to the block on the rocking of the arm 10 such as will be imparted to the latter on the movement of the handles 5 and 6toward and away from each other.

The block 15 is connected to the link 12 by means of a pin 16 which is passed transversely through the bar, across the slot and plvotally engaging the link as does the pin 13. j

On that face of the bar 15 opposite the arm 10 there is formed a circular stud 17 this stud paralleling the bar 3 and being formed on that side opposite the bar 3 with a plurality of spaced teeth 18 in which the threads of a worm 19 may engage, this worm being pivotally mounted at one end by having its stud 20 engage a suitable bearing Thus the turning of the work 20, because of its engagement with the teeth of the stud 17 will efl'ect the adjustment of the active jaw 2 with reference to the bar 15. Therefore,

when the handles are at rest with respect to.

each other, the active jaw may be adjusted with reference to the passive jaw. 7

With the handles 5 and'6 in closed positionthat'is, in a position when the upper edge of the arm lO engages the under face of thebar 15, as shown in Fig. 2 of the drawings,the active jaw is adjusted to suit the nut or pipe to be engaged by the device. WVhen it is desired to release the jaw from engagement with the nut to change the position of the device, the openings of the handles will eflect this, the bar 15, as a result of this movement of the handle, sliding down the bar 3 and carrying with it the active jaw 2, thus separating the space between it and the passive jaw and permitting the two to be readily disengaged from the nut onpipe for the purpose of effecting a neW grip.

wide distances off to provide parallel ribs 22, the slots adjacent the outer ends of the jaws being narrow slots and positioned close together to provide the radial biting teeth 23 which are wedge shaped in cross section. Certain characters of pipe may necessitate the two jaws engaging the pipe,by means of the teeth 28, while other characters of pipe on which the wrench is to be used may be better engaged by the teeth 22. Neither the teeth 22 nor the'teeth 23 will prevent the effective operation of the two jaws on a nut.

The invention havin rbeen described, what is claimed as new and useful is:

A tool of the kind described comprising a passive jaw formed with a bar, an active jaw slidably mounted on said .bar and movable toward and away from the passive jaw, a pair of pivotally connected handles one of which is integrally connected with the bar and the other of which is formed with an arm in whose upper edge is formed a slot, a block slidably mounted on the bar and having a stud entering and loosely engaging the active jaw and formed with spaced teeth on one side, a link seated in the slot in the arm and pivotally connected with the arm and also pivotally connected with the block and a worm rotatably mounted on the active jaW and engaged with the teeth in the stud.

' Int-estimony whereof I affix my signature.
