This invention relates to pliers and has for the primary object, the provision of means whereby the j aws are capable of adjustment into varying working positions and capable of a greater number of adjustments than is possible to obtain with the conventional type of pliers, thereby permitting the gripping of objects having a much larger variance as a to sizes than heretofore possible when employing the conventional type of pliers for such work.

WVith this and other objects in view, this invention consists in certain novel features of construction, combination and arrange- ..1 ment of parts to be hereinafter more fully described and claimed.

For a. complete understanding of my invention, reference is to be had to the following description and accompanying drawings,

in which Figure 1 is a plan view. illustrating pliers constructed in accordance with my invention and showing the jaws adjusted into a. ,working position of the smallest degree.

--' Figure 2 is a similar view showing the jaws adjusted into a second working position. Figure 3 is a plan view illustrating the pliers adjusted in a second working position with the jaws separated to their fullest ex-. tent.

Figure 4 is a similar view illustrating the jaws adjusted into a third working position and positioned in a fully separated position.

Ijeferiring indetail to the" drawings,. the

numeral 1 indicates pliers including handles 2'and 3 formedintegral with'body portions 4 and 5, respectively. Jaws6' and 7 are formed integral with thebody portions sand 5 as shown in Figure 1; The body portions 4 and 5 are pivotally connected by a headed: bolt 8 extending through said bodies and having oppositely disposed fiattenedlfaces 9* and a nut 10 threaded thereon wherebythe jaws 6 and 7 may be moved relative to each other by the movement of the handles 2 and 3. The body portion 5 is provided with an elongated slot 11, thewalls. of which are arcuately curved at spaced intervals to pro. vide bolt receivingchambers 12, 13,-and-1t" having communication with each other by restricted portions. The restricted portions are'of such a size that the bolt 9 .may move' from one chamber to another when said bolt. is positioned with the flattened faces 9 paral lel with the restricted portions between saidchamb'er's,however, when the bolt 8 is positioned with the flattened faces 9 disposed at an angle to the restricted wall between said chambersfthe bolt will be prevented from moving from one-chamber to'another.

The body portion '4 is provided with an elongated slot having chambers 16 and 17 for'med'in each'end of'the slot and being in when the flattened faces are disposed angularly with the. passage between said -cham-.

b ers. However, when the bolt is positioned I m .pmce l with the flattened facesf 9 parallel with the walls of the restricted passage, said bolt may be moved'from one chamber to the other. It

is to be understood that when the boltis po-' sitioned to'pivotally connectlthe body por! tions 4 and 5 it extends through the slots 11 and 15. V

A locking plate 18 is mounted on the bolt 8 between the head thereof and the body portion 4 and is provided with a tongue 19 adapted to engage into either of the notches or recesses 20 and 21. The locking plate 18 is provided with an elongated opening 22 to receive the bolt and the flattened faces 9 thereof for securing the locking plate against rotation relative to the bolt. A finger piece 23 is formed on the locking plate 18-whereby the latter may be moved to engage either the notch 20 or the notch 21.

With the body portions 4 and 5. positioned as shown in Figure 1, the jaws 6 and 7 are'set at a zero working position and by position-- 7 ing the handle 3 at right angles to the handle 2, the bolt 8 may be slid from the chamber 12 to the chamber 13 providing a second working position for the jaws as shown in Figure 2. By positioning the=handles '2 and 3 again in the foregoing stated position, the

' bolt 8 may be moved from the chamber 13 to the chamber 14 giving a third working position for the aws as shown in Figure 3. With the bolt occupying the chamber 14 and mov- 7 ing the locking plate or the tongue 19 thereof out of the notch 21 into the notch 20, the bolt may then be moved from the chamber 16 of the .body portion 4 into the chamber 17 thereby providing a fourth working position for the jaws.

' When it is desired to return the jaws to their zero workingposition as shown in Figure 1, the operation heretofore described is repeated in a reverse manner. Therefore, it will be seen that an adjustment between the jaws has been provided which is capable of permitting the jaws to grip objects of varying sizes and to a range of sizes considerably greater than can be gripped by the conventional type of pliers in which one'body portion is provided with a slot similar to the slot 15 while theother portion is provided with an opening to permit the bolt or pivot to extend therethrough. V V While I have shown and described the preferred embodiment of my invention, it will.

be understood that minor-ohangesin construction, combination and arrangement .of parts may be made without departing from the spirit and scope of my invention, as

. claimed.

Having thus describedmy invention, what I claim is: I v

Pliers comprising body portions, handles on said body portions, jaws on said body portions,-said body portions having slots provided with spaced restrictedportio'ns and enlarged portions formingchambers with communicating passages, a' pivot bolt having oppositely disposed flattened faces extending 2 through the slots and capable of being moved another chamber for adjusting the body portions relative to each other whereby the jaws may be adjusted to various working positions,
