'.PLIERS AND SIMILAR TOOL.

Specification of Letters Patent.

Patented June 23, 1914.

T0 all whom it may concern.'

Be it known that RANDOLPH HAYDEN, late a citizen of the United States, residing at Haddam, in the county of Middlesex and State of Connecticut, did invent certain new and useful Improvements in Pliers and Similar Tools',-of which the following is a specification.

This invention relates to improvements in pliers and similar tools, and the object or' the improvement is simplicity and economy in construction and convenience and eiii ciency in use.

In the accompanying drawing -Figure 1 is a plan view of a pair of pliers embodying this invention. Fig. 2 is a sectional lview on the line w of Fig. 1. Fig. 3 isa similar View on an enlarged scale and in part broken away of the same. Fig. 4 is a similar view of the same before securing the handle and blade members. Fig. 5 is a similar view of the handle element. Fig. 6 is a plan view of a development of the same. Fig. 7 is a plan view of one of the blade elements. Fig. 8 is a side elevation of the same. Fig. 9 is a plan view of some of the parts shown in Fig. 1. Fig. 10 is a sectional view on the line y 'y of Fig. 9.

The pliers comprise a pair of members A pivotally connected by apivotal pin or rivet B having each a handle proper 15 at one side and a cutting edge or jaw 16 on the other side of the point of pivotal connection.

As shown, the two members A are similar. In some cases for special reasons it may be desirable to make the cutting elements of the two members dissimilar. Otherwise the two pivotally connected members A are substantially alike.

The members A comprise each a handle element 17 and a liaw or blade element 18 which are connected in a manner to be described.

The blade element 18 is formed of sheet material of appreciable thickness and comprises a shank 19 at one end, a blade 20 having the cutting edge 16 at the other end and a hub portion 21 intermediate thereto, the latter being provided with a hole 22 for the pivotal pin B.

The hub portion 21 is provided at the outer edge with a rearwardly directed tongue or lug 23 that overhangs the adjacentl outer edge 24 of the shank 19 and is separated therefrom by a rearwardly directed notch or recess 25. The said outer edge 24 of the shank 19 is curved :from the eX- treme rear tip end 26 to the bottom or inner wall of the recess 25 suitably to give proper shape Jfor the handle member 17 that is seated thereon in a manner to be described.

At the inner edge 28 the shank 19 is provided with an inwardly directed stop lug 27 that is suit-ably positioned to engage with the corresponding stop lug 27 on the mating member A to limit the pivotal movement of the members A. Furthermore, on the said inner edge 28 between the stop lug 27 andv the tip end 26 there is an'inwardly directed notch f or recess 29. Otherwise, the said inner edge 28 is substantially straight.

The handle member 17 is made of a stripof sheet metal. The ends of the blank mayv be given a special shape for the sake of appearance, as for instance, the inner end 30 may be rounded and the outer end may comprise a portion 31 of the edge cut olf at right angles to the length of the strip and lateral portions 32 cut at an angle or divergent as shown.

The strip for the handle member 17 is made into channel formation or U-shape in suitable dies suitably to receive the blade member 18 and at the same time is given a compound curve or S-shape to provide a suitable shape for the handle proper 15.

rlhe shank 19 of the blade element 18 is received in the inner end of the U-shaped handle member 17, the outer wall 33 of the handle member 17 being engaged with the outer edge 24 of the shank 19 and the upper and lower ange portions 34 of the handle member 17 covering the upper and lower faces of the shank 19 and the inner end 31 of the handle member 17 being received in the notch or recess 25, and with the inner edges 35 of the handle member 17 substantially in line with the inner edge 28 of the shank 19. In this position the inner edges 35 of the handle member 17 overhang the recess 29 in the shank 19 and the tongue or nose 23 overhangs the inner end 31 of the handle member 17.

With the handle member 17 and the blade member 18 engaged as described, a blow on the ianges 34 operates to close the said anges 34 over the shank 19 and'bring the overlapping portions 36 that overlap the recess 29 into the said recess and thereby effect a..

member 18. In other Words, by the indentation of the edges of the handle member 17 so as to enter the recess 29 a positive positioning and locking of the handle member and blade member is effected.

The engagement of the end 31 of the handle member with the nose 23 serves to coperate with the holding and locking means described to resist the operating strains that are produced in the use of the instrument due to forcibly pressing the handles proper 15 toward one another as When some object held is between the jaws or cutting edges 16.

As described, the handle member is positively connected to the javv member by means that involve simply a closing or deforming operation on the edges of the flanges of the handle member and at one portion thereof only. Accordingly, in effecting the connection mentioned, the blade member is not changed or deformed in any Way, and

- for this reason the said blade member can;

be made of uniform material throughout. That is, the blade member can be made of? steel and can be hardened and tempered throughout the entire length.

Diil'erent forms and styles of cutting edge may be provided for different uses.

The invention claimed is 1. In a tool of the class described having a pair of pivotally connected members, one of the said members comprising a jaw member and a handle member, the said jaw member being provided with a pivot hole, and comprising a jaw at one side of t-he saidE hole and a shank at the other side, a nose overhanging the outer edge of the saidv shank, the said shank having a recess 0n t-heA inner edge, the said handle member comprising a strip of ysheet material bent into chan- Y the said recess.

2. In a tool of the class described having a pair of pivotally ,connected members, the said members comprising each a javv member and a handle member, the said jaw member being provided With a pivot hole, and comprising a jaw at one side of the said hole and a shank at the other side, a nose overhanging the outer edge of the said shank, the said shank having a recess on the inner edge, the said handle member comprising a strip of sheet material bent into channel form and inclosing the said shank, one end ofy the said handle member being engaged-With the said nose and a portion of the said handle member being engaged with the said recess.

3. In a tool of the class described having a pair of pivotally connected members, one of the said members comprising ajaW member having a hub portion`providedwithV a `pivot hole, a jaw at one side anda shank at the other side thereof, a nose on the said hub portion overhanging the said shank,

the said shank provided Witha recess, and

the said handle member formed of sheet metal and secured to the said jaw member -by having one portion engaged With the said nose and another portion engaged With the said recess.
