* :S-tBe-it known that I, ERNEST- A. GEMENY,ja

citizen of-the United States, residing at J unc- -tin City, in the'county of Geary and State of Kansas, have invented certain new and useful Improvements in Pliers, of which the following is a specification;

for cutting insulated wires.

The resent invention relates to certain new an useful improvements inipliers of the wire cutting type, and has specially in view the production of wire cutting pliers adapted The principal object'of the invention is .to provide a novel form of insulated wire cutting pliers, in which a pair of laterally rojecting auxiliary cutters are employs to first cut through the insulation, and then guide the'wire to a position where it will be severed by the main cutters.

3 of reference designate corresponding parts,-

, to that shown in Fig. 3-.

Figure 1 is a'perspective view of the pliers, showing the same with the jaws closed. Fig. 2 is a similar view, the jaws being open. Fig. 3 'is a side elevation of the pliers showing the jaws opened. 1 Fig. 4 is a side elevation of the jaws, the view being of the oppositeside Fig. 5 is an end elevation showing the jaws opened.

Referring to said drawings, 1011 designate two grip ing jaws, the general outline of which are oi pliers, "and which are provided with handles 121? the jaw 10 carrying a housing 14 within which the jaw 11 is fulcrumed. On one face the jaws, intermediate their reduced gripping ends and their pivotal connection, are recessed as at 15-16, to form seats for the elongated projecting wire cutters 1718, the cutt ng edges of which are beveled.

' 'One end of the upper surface of the wire cutter 17' is reduced in thickness to form a V-shaped recess 19. The bottom of the recess is projected outwardly to form a thin V-shaped insulation cutter 20, having a sharp penetrating point 21 and outwardly inclined sides 2223.

One end of the under surface ofthe wire cutter 18 is reduced in thickness to form a Specification of Letters Patent.

the usual type of cross handle V-shaped recess 24. n ofuter endf of the cutter 18, above the "V' shape'd 'reces's"24,i's' projected outwardly to form a thin insulation cutter 25, 'l'iawing a'sharp fpene trating point 26 and outwardly ihclined sides' 27i28. i I i I The two insulation cutters 20 25i iielo cated in opoosite osi'tioiisftind arrangedjin horizontal p anes s ightly above oneano'tlier," so that when the pliers train the closed position as shown in F ig.-1 ofthe 'drayi' ihgs',the cutter 25 will besnuglyseated'flush in V-shaped recess 19 at tlie'end of the upper surface of the wire cutter 17, and the insulation cutter 20 will be snugly seated flush within the V-shaped recess 24 at the end of the under surface of the wire cutter 18.

.In using the pliers, the insulated wire is caught between the points. of the insulation cutters 20-25. Pressure applied upon the handles will force the said points through the insulation and cause the inclined cutting edges thereof to cut through the insulation, and at the same time gradually force the .wire rearwardly to a position where the wire insulation formed by the insulation cutters, and act upon and sever the wire.

l?atente. May 26.5190 Application filed February 15', 1908. Serial No. 416,154".

From the foregoing it will be observed that the present invention provides a simple and eiiect-ive means for cutting through the insulation, and at the same time imparting a rearward movement to the wire causing it to move to a osition where the elongated wire cutters will enter, the out made by the pointed insulation cutters, and thereby be in a position. to have a direct cutting action upon the wire only.

An important feature of the invention is in the manner of locating the insulation cutters opposite one another, but in different horizontal planes, which provides for an overlapping joint between the two cutters when the pliers are closed, causing each cutter to enter its corresponding recess, thereby disposing the sharp points and cutting edges in a position where there is no danger of injury being done to the user when the pliers are in their inoperative position.

The wire cutters just described are to be, associated with jaws having flat gripping" faces 31-31, subserving the ordinary plier are provided with V-shaped cutter notches iio 8O cutters 1718 will enter the opening in the 3131 in opposing relation to form an auxiliary wire or rod cutter.

I claim':

1'. An implement of the character described comprising a pair of pivoted jaws each provided with a cutter seat, a Wire cutter in each of said seats, the upper surface of one end of one of said wire cutters being reduced in thickness to form a recess and a thin outwardly projecting'insulation cutter, the under surface of the other wire cutter being reduced in thickness to form a recess and an outwardly projecting insulation cutter, whereby when the jaws are closed, the said insulation cutters will be disposed in an overlap ing position with their cutting edges in sa1 recesses.

2,' An implement of the character de. scribed comprising a pair of pivoted jaws each provided with a cutter seat, a wire cutter in each of said seats, one end of said wire cutters being recessed and provided withinsulation cutters, said insulation cutters and each providedwith a cutter seat, a wire cut ter in each of said seats, each of said wire cutters having one end reduced in thickness to form recesses and thin projecting insulation cutters, said insulation cutters and recesses being so arranged relatively that when the jaws are closed the said insulation cutters will be disposed in an overlapping position with their cuttin edges in said recesses.

In testimony w. ereof I hereunto afiix my signature in the presence of two witnesses.
