PLIERS.

Application mea Nvember 2o, 1922. seriai Nc. 602,093.

To all whom t may concern.'

Be it known that I, WILLIAM M. VAY, a citizen of the United States, residing at Coalinga, in the county of'Fresno and State of California, have invented certain new and useful improvement-s in Pliers; and I do declare the following to be a full, clear, and enact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

rihis invention relates to improved pliers and it has for'its principal object to generally improve npon tools of this class'by providing one embodying crossed handles which are connected together by unique means broadly referred to as a doublejfulcrum and connection, the same embodying spaced pins extending through elongated slots in a manner to permit the aws tov be spread a greater distance apart than would be permitted by a single immovable or adjustable pivot such as is commonly employed Another and important object of the invention is to provide a connection of 'the aforesaid type which insures rigidity of construction and a very effective grip of the jaws on the object being acted on7 the connection in its preferred construction embodying;` a pin carried by and movable with each jaw and extending slidably through a slot on the other jaw, this arrangement assuring an equal distribution of strain on the parts.

Other objects and advantages ofthe in-I vention will be apparent during. the course of the following description.

in the accompanying drawings forming a part of this specification and inwhich like numerals are' employed to designate like parts throughout the same: Y

Figure l isa side elevational view of a tool constructed in accordance with this invention showing the jaws spread apart to an intermediate position. Y

Figure 2 is a top plan view of the tool.

Figure 3' is an elevational view of the outer end of the tool showing the jaws closed and the relation of the connecting pins at this time.

Figure 4 is a longitudinal detail section taken on the line 1 -4: of Fig. 3.

Referring to the drawings by numerals, i and 2 designate a pair of crossed handles which are provided at their outer ends with integral jaws 3. It may be noted that the portions of the handles which cross one another, are increased in width considerably to accommodate the unique double fulcrum and connecting means. y Y

Although the last named means could be of some other construction, it by preference Y comprises a pair of Y elongatedA slots 4, one being formed` inthe widened portion of each jaw and these slots being arranged in divergent relation. In addition to the handles being equipped with the slots, each one is formed with a` comparatively small opening 5 through which a connecting and pivot pin 6 extends. The small op-ening on one handle registers with the elongated sloty on the other handle. Hence, the pin which eX- tends through the opening also extends through the registered slot. ,One endV of each pin is threaded and a nut 7 is arranged 'thereon to connect the handles together'.

Normally, when the jawsare lclosed as seen in Fig. 3, the then adjacent ends of the slots register with one another and the pin and small openings through which they vex-y tend are disposed at the opposite or remote endsof the slots. Now, bygrasping the handles and moving them apart, it is obvious thatthe pins will engage the longitudinal edges of the slots' and will be moved toward the opposite outer ends thereof as disclosed in Fig. l. -When the jaws Yare spread their maximum distance, the pins will have moved close together-and will be seated in the last named ends of the slots.

Hence, when the jaws are engaged with an object,fthe strainwill be distributed equally to the two connecting pins. Consequently, a much stronger construction is provided than is had with the single pin and slot connection commonly used. In this connection it may be stated that the present invention is vastly different from the type ofl connection just mentioned for in order to obtain the additional adjustment of the jaws with the Vusual slip joint, the connecting and pivot pin must be moved manually from one end of the slot tothe other and with this arrangement when the pin is at one end of the slot, the jaws do not come into direct engagement with one another. With my arrangement, the pin does not remain at one Vend' of the slot when the handles are spread, but the twofpins automatically and simultaneously move from one end' of the slots to the opposite ends the moment the handles are spread and this allows for the additional adjustment. Particular emphasis is therefore to be laid on this new method of operation for accomplishing the result sought.

Attention is here directed to the fact that the present application is a continuation in part of an application for pliers l'ed by me on August 25, 1921, the same having been designated by the Serial No. 495,230, but. having been abandoned in view of the present improved construction.

By carefully considering the description in connection with the drawings, persons familiar with devices of this class will doubtless able to obtain a clear understanding of the invention. Thereforea more lengthy and detailed description is deemed un,- necessary.

Since probably theibest results may be obtained with the construction and arrangement herein yshown and described, 'this is' taken as the preferred embodiment of the invention. However, I wish it to beiunderstood that minor changes coming within the scope of the invention as claimed may be resorted to if desired. f

I claim:

l. Connecting means for the handles of a tool of the type specified embodying a pin carried by and movable with one handle and extending slidably through a slot in the other handle, said pin being disposed at-one end of the slot when the jaws are in engagement with one another and beingY automatically7 moved to the opposite end of the slot as the handles are spread apart, whereby to permit additional adjustment of the jaws to be had.

2. Connecting means for thefcrossed handles of pliers comprising a pair of pins eX- tending through and automatically slidabie in elongated slots when the handles are moved toward and from each other.

3. The structure as set forth in yclaim 2, wherein said slots are inclined with respect to one another.

4. Pliers comprising a Vpair of crossed handles having jaws at their outer ends, the crossed portions of the handles being equipped with relatively inclined slots, and pins extending slidably through the slots for connecting the handles together, said pins being movable automatically from end to end of the slots when the handles are actuated.

'with the overlapping portion of the handles for pivotally connecting them together,n

said means embodying a pin carried by one handle and extending through an elongated slot formed in the other handle, said pin being movable from end to end of the slot` and being disposed at one end of the slot when the jaws are together and being automatically moved to the opposite end when the handles are actuated.

6. A tocl of the class described comprising a pair of crossed handles, the overlapping portion of each handle being equipped with spaced openings, the openings in one handle registering with the openings iii the other handle and pins passing through and slidable in two of Ythe openings when the handles are actuated. Y

7. A tool of the type specified comprising a pair of crossed handles, the crossed portions of said handles being'Y equipped with small unregistered openings and elongated slots, the adjacent ends of the slots registering when the handles are together, and connecting means extending through the small openings and slots and slidable in the latter when the handles are actuated.

' 8. A tool of the class described comprising a pair of crossed handles, the crossed portions of each handle being equipped with a slot, the two slots being disposed in divergent relation :with respect to one another, and the adjacent ends thereof registering with one another when the handles are close together, and pins carried by said crossed portions and extending through said slots.

9. A tool of the class described comprising a pair of crossed handles, the crossed portions of the handles being widened and each portion being equipped with a relatively small opening and elongated slot, the slots of the respective handles being disposed in divergent relation, and connecting and pivot pins passing through the small openings in one handle and through the slots in the other handle, said pins being disposed at the remote ends of the slots when the handles are together but being automatically moved to the opposite ends of the slots when the handles are spread apart.

Iii testimony whereof I have hereunto afliXed my signature.

WILLIAM M. WAY.
