Specicaton of Letters Patent. i Patented Aug, 23, 1921.
Application filed February 19, 19,20. Serial No. 359,964.
or connection of two wires may be quickly" and easily made, eliminating to a material extent, the time absorbing operation of skinning the ends of the wires, which are to be connected.. in the usual manner,v such as by means of a pocket knife.
Another ob'ect of this invention, is to pro-.
vide a pair o pliers as specified, the jaws of which are provided with a plurality of arcuate sharpened portions, graduated in sizev and decreasing .in diameter as they are disposed remote from the aXi's of the pliers, so that the larger opening for cutting the insulation and pulling it from the larger gage wire is closer to the axis of the pliers, than the opening for stripping the insulation from the smaller -gage wire, and also to provide cutting edges between the two larger openings' for coyering and cutting the conducting wire itself. v
A further object of the' invention is to provide'ppenings at the outermost ends of the jaws'tof the pliers lfor engaging the conductor wires after they ,haveQ been,v stripped of insulation .to hold them to facilitate the twisting of the wires together to forni' a secure joint. y j -Other objects of the invention will' appear in the following detailed description taken in connection with the accompanying draw# ings, forming a part of the specification, and in which drawing: j Figure 1 is a side elevation of the proved pliers. c
Fig. 2 is a horizontal enlarged y section taken on'the line 2-2 of Fig. 1.
Fig. 3 is a detail perspective View of one of the jaws of the pliers.
Fi 4 is an enlarged section through the pliers showing'the jaws thereof in the ac-l tion of cutting the insulation about an inl sulated electric conducting wire. I
Fig. 5 is a view illustratingla fragment of the jaws of the pliers gripping the meeting )wires is cut, at the'desired distance from the 1 .10 and 11,
endsv of two wires whichare and j Fig. 6 is a detail view of an ordinary electric -conductor illustrating the method of stripping the insulation therefrom.
to'be connected,
ings, wherein like charactersv indicate like and corresponding parts throughout the several views, the jaws 10A and l11 of the pliers are pivotally connected, by means of a pivot pin 12 as is ordinary in the construction of approved types of pliers, and these .jaws have handles 13 and 14 connected thereto or formed thereon, and extending upon the op- Referring more particularly to the drawposite side of the pivot pin l2 from the jaws 70 to permit the manual operation of the jaws.
Thefacing edges or sides of the jaws l0 and 11 are cut away or .recessed from one f side, in substantially an egg shape, or oval shape, as clearly shown at 15, in Figs. 1 and 4 of theldrawing, and the. abutting relatively thin portions of the jaws-are each' provided with'scml-circular openings 16, graduated in size, and gradually' decreasing in diedges of the jaws extending inwardly into ameter from the axis or pivot pin 12 of the jaws, as clearly shown Iin the drawings.' TheV the recess 15 at theopenings are beveled as 85 shown at 17, forming cutting edgesl 18, which are adapted to .cut through the insu lation A of an electric conductor or Wire B of approved 'construction as illustrated, in Fig; 4 of the drawings. Positioned Vintermediate the two largest openings 1 6 is an oval shaped depression 19, the same being formed by substantially semi-oval Adepressions formed in each jaw, and this oval cned, for cutting the wire or conductor B.
their facing surfaces flat,l for 'facial abutment, and these flat surfaces 20 are provided with'semi-oval recesses 21, graduated in size to form Various sized oval openin s when ends of two wires, such as the wires'B 'and illustrated in Fig. l5, the insulationA of the shaped depression 19 has its edges sharp- The outer ends of the-jaws 10 and 11 having 10'0 the jaws 10 and 11 are closed as s own' in` ends of the wire, and in so cutting, the Wire should be placed in the semi-clrcular re-v cesses y16 the diameter of which is eater thanthe diameter of the wires B or so as to-insure against the cutting, or rupturing, of the wire, when cutting the insulation, and
. the outer braiding, or cross covering of the insulation is stripped off by pulling theclampi-ng the wires therein, after which the f ends of the wires are twisted about each other,
that is,the ends of the wire C is twisted about the wire D while the end of the wire D is twisted about the wire C, as indicated in Fig. 5, and as is the usual procedure in 'conl necting the meeting ends of two electric conductors; After the wires have been twisted,
as shown' in Fig. 5 of the drawings, the
- pliers are released, and the 'two'wires are drawn apart, bringing the convolutions into engagement with each other and forming a secure connectionbetween the wires, which is completed, when itis properly bound or wound with the usual type of adhesive nedges graduated in size as thy1 to reduce the thickness thereof through a certain length of its face edge, the reduced faces of said jaws each havlng a plurality of coperating semi-circular recesses therein having -insulating stripping beveled knife varg positioned from the jaws pivot, e reduced faces of saidijaws having coperating and abutting wire cutting:l beveled knife edges thereon. l
2. In pliers, the combination of a pair of pivoted jaws, each of said jaws having a portion cut away upon one side and face, to reduce'the thicknesstheref throughout a certain length of its face edge, said reduced thicknesses terminating short of the forward end of said jaws, the reduced faces of said jaws each having a plurality of lcoperating semi-circular recesses therein provided with beveledsknife edges, and said jaws having coperating semi-circular depressions in the facing edges thereof. upon their forward ends at the place of normal thlckness.
