JOI-IN R. SHAW, OF RURAL VALLEY, PENNSYLVANIA.

Application led April 5, 1911.

To all whom t may concern.'

Be it known that I, JOHN R. SHAW, a citizen of the United States of America, residing at Rural Valley, in the county of Armstrong and State of Pennsylvania, have invented certain new and useful Improvements in Tools, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to tools for splicing wires and electric conductors, and the object of the invention is to provide a novel tool for cutting or shearing the ends of wires whereby the wires can be interlocled to form a positive and non-leakable connection between two wires for an electric current.

My invention aims to provide a tool constructed upon the principle of a pair of pliers, and to furnish a tool with detachable jaws for accurately cutting the ends of wires, whereby the wires will fit rtogether and interlock to provide aplurality of contacting surfaces.

The invention will be hereinafter described in detail and claimed, and reference will now be had to the drawing wherein there is illustrated a preferred embodiment of the invention, but it is to be understood that the structural elements thereof are susceptible to such changes as fall within the sccpe of the appended claims.

In the drawing z-Figure l is a side elevation of a tool in accordance with this invention, Fig. 2 is a vertical sectional view of a portion of the same. Fig. 3 is a plan of the female jaw detached. Fig. 4 is a side elevation of the same. Fig. 5 is a plan of the male jaw detached. Fig. 6 is a side elevation of the same. Fig. 7 is a plan of one of the heads of the tool. Fig. 8 is an elevation of a wire splice as accomplished by the tool, and Fig. 9 is a cross sectional view of the same.

A tool in accordance with this invention comprises two handles or

levers

1 and 2, the handle 2 'having the outer end thereof enlarged, as at 3 and provided with a slot 4 to receive the enlarged portion 5 of the handle 1, said handle being of a size to pass through the slot 4 and thus permitof the handles being assembled. The enlarged

portions

3 and 5 of the

handles

2 and 1 are pivotally connected together by a transverse pin 6 extending through the enlarged

portions

3 and 5. The outer ends of the enlarged

portions

3 and 5 are provided with Specification of Letters Patent.

ings 13 for screws 14 adapted to screw into l the openings 9, said screws having the heads thereof counter-sunk in the jaw. The inner side of the jaw is provided with a longitudinal tongue 14a adapted to fit in the groove 8 and prevent lateral displacement, `and'the outer face of the jaw is provided with a central transverse groove 15. The bottom of this groove is stepped or provided with

longitudinal ribs

16 and 17, the rib 16 relatively to the side walls of the groove 15 being of a greater height than the rib 17, for a purpose that will presently appear. The jaw 1l adjacent to the inner edge thereof is provided wit-h a longitudinal groove 18 intersecting the

ribs

16 and 17 and longitudinally alining with the openings 19 adjacent to the inner edge of the aw 11.

4The head 7 of the handle l is provided with a male jaw 20 having screw openings 21 and dowel pin openings 22 similar to the 11, and on its inner face provided with a longitudinal tongue 23 adapted to engage in the groove 8 of the head 7. The inner face of the male jaw 20 also has a transverse groove 24'an`d the bottom of this groove is stepped the reverse of the groove 15, as at 25. The front side of the jaw 2O has an extension 26 and said extension has the under side thereof stepped to longitudinally aline with the stepped portion of the groove 24. One of the ribs of the eX- tension 26, designated 27 serves functionally as a cutting device for the end of a wire, this particular rib entering the innermost groove 28 of the jaw 11. lVhen a piece of wire is placed in the openings 19 and the groove 18 and the jaws closed, the extension 26 immediately cuts the outer surface of the wire, whereby the wire will present a transverse groove 29 and shoulders 30, the wire being simultaneously cut by the rib 27. Vhen the jaws are opened and the wire removed the cut end of a wire may have iins 31, and to remove these fins, the c011- fronting sides ofthe handles l and 2, adj a* cent to the enlargements thereof, are provided with arms 32 adapted to engage the piece of wire and compress the fins 3l suiiiciently to provide a smooth surface upon the wire. Another wire is similarly out by the tool and then the cut endsof the wires can be placed together, as shown in Fig. S whereby .the groove 29 of one wire will re ceive the rib 32 of the other wire and the shoulders 30 of both wires abut. The interlooked-ends of the wires can then be fused,

wrapped or otherwise permanently con-- neeted.

The tool in its entirety is made of strong and durable material and can be made of various sizes.

Vhat I claim is L A tool of the type described comprising pivoted handles, heads carried by the outer ends of said handles, jaws detachably connected to said heads, one of said jaws having a groove formed therein and openings adapted to' receive a piece of wire transversely of said groove, and an extension carried by the other jaw and adapted to enter said groove and cut a piece of wire held by said jaw to provide the same with shoulders whereby two cut pieces of wire can beinterlocked.

2. A tool of the type described comprising pivoted handles, heads carried by the outer ends of said handles, jaws detachably connected to vsaid heads, one of said jaws having a transverse groove formed therein, ribs carried by the bottom of said groove, said jaw having openings formed therein to receive the end of a piece of wire, and an extension carried by the other said jaw and adapted to enter said groove and cut the piece of wire held by said jaw and provide the same with shoulders, substantially as described. Y

3. A tool of the type described comprising pivoted handles, jaws vdetachably connected to the outer ends of said handles, one of said jaws having a transverse groove formed therein and openingsadapted to receive a piece of wire, and an extension carried by the other aw and adapted to enter said groove and provide the wire held by the other jaw with shoulders whereby two kwires can be interlocked.

4. A tool of the type described comprising handles, having the outer ends thereof pivotally connected together, heads carried by the pivoted ends of said handles, a male jaw detachably connected to one of said heads, a female jaw detachably connected to the other said head, said female jaw having a transverse groove formed therein, longitudinal ribs upon the bottom of said groove, said female jaw having openings formed therein whereby a piece of wire can be arranged transversely of said groove, an extension carried by said male j aw and adapted to enter the groove of said female jaw, a depending rib carried by said eXtension and adapted to out the end of the wire mounted in said female jaw, said extension having the bottom thereof shaped to coperate with the ribs of said female jaw in providing the piece of wire with shoulders, whereby two wires similarly cut'oan be interlocked, substantially as described.

5. A wire cutting tool comprising two pivotally-connected handles, jaws carried by the outer ends of said handles, one of said jaws being'a male and the other a female jaw, the female jaw having a transverse groove and provided with wire-receiving means, the wire being received in the jaw longitudinally of the latter, a cutting rib carried by the bottom of said transverse groove, and a cutter carried by the male jaw, said cutter' being received when the aws are closed in the transverse groove of the female jaw and cooperating with the rib of the female jaw to provide the wire with a transverse groove.

6. A wire cutting tool comprising a pair of handles pivotally-connected together, one of said jaws having a transverse groove and provided with wire-receiving means, ribs carried by the bottom of said groove; an eX- tension constituting a cutter carried by the other jaw for entering said transverse groove to engage the wire and provide the latter with a transverse groove, and a outting rib carried by said cutter to cut the wire transversely.

7. A wire cutting tool comprising a pair of pivotally-connected handles, jaws carried by the outer ends of said handles, one of said jaws having wire-receiving means and having a groove extending transversely of the wire-receiving means, and a cutter carried by the other jaw to be received in j said groove as the jaws are closed, said cutter having means to provide the wire with a transverse groove and also to cut the wire transversely.

In testimony whereof I affix my signature in the presence of two witnesses. Y
