To all whom, it may concern:

DIVISION B.

of insulated wires or conductors, or a single Be it known that '1', RICHARD S. \VARING, aheavy wire or conductor sufliciently large to citizen of the United States, residing at Pittsburg, county of Allegheny, State of Pennsylvania, have invented or. discovered a new and useful Iinprovementin Branching ElectricCables; and I do herebydeclarc the following to be a full, clear, concise, and exact description .thereof, refereiice being had to the accomparo' nying drawings, making partof this specification, inwhich-like letters indicating like parts- Fign re 1 represents an elevation of a section of cable, showing the method of connecting sections of cables and of branching one or more of the conductors at any desired point. Fig.

' 2 represents a view partly in side elevation and'partly in longitudinal section, showing themanner; of'connecting the wirsfa'rid' also i o theinitial steps of the. method of branching the insulatedwires or conductors. Fig. 3 represents views of -theflattened wires.

This invention relatesto' cer'tain improvements in that class of cables for the transmis- 5 slon of electric currents which are composed of insnlatedwircs surrounded by an armor of lead or other ductile material, the said armor beingformedwith longitudinal ribs, with the insulatedwires or'conductors extending through them, and which may also be provided with a.

oeutralor longitudinal insulated wire or group of wires.

My invention consistsin an improved method of forming branch connect-ions at any point-in the cable or section thereof by cutting through one or more of the ribs transversely and longitudinally a suitable distance, opening the partsoutward, then severing the insulated conductor, bending-the ends so formed outward,

0 and closing the divided'partsof the armoring thus opened, and soldering the same.

The cable is constructed of an armor, of lead or other ductile material, provided with a series of longitudinal ribs, a, through which extend longitudinally the. wires or conductors c, surrounded with insulating material b. The

; grooves k bween the ribs'may be of any desiredshape or-dept-h, and the armor may he provided with a ceutial longitudinal passage,

which may he corrugatedor plain, for a group light or other like purposes. In order to form I intermediate branches, the ribs arecut longitudinally and transversely, as shown in Figs. 1 and 2,;forming lips ff, which are bent outward laterally, exposing the wire or conductor, which is denuded of its insulating material, as shownat e, Fig. 2.- The wire-or conductor is then cut, and the ends are bent-outward, as shown in Fig. 1, aft'erwhich the lips are bent, back into place and soldered, leavingthe-wires or conductors otherwise, to be united to any desired branch line. In uniting these tnrnedsoutendsc to the branch conductors, I may flatten the ends c and arteries-onus branch,as'shown in Fig; 3, and then place the -flattened ends together, and secure them in-thatr'position by wrapping the lapped ends with wire, and cover the whole joint with solder, and finallycover'the whole joint with insulating material. A- small tube, of lead or other suitable material, may be placed over each branch and soldered to the cable. To connect the wires or conductors of the difi'erent sections, the said wires are de-. nnded and flattened at their ends,as indicated projecting at right angles or in Fig. 2 of the drawings by the letter 9. To

further secure the connection, the matched ends of the wires or conductors are bound with' fine copper another wire, or with fibrous'mw terial, and in the latter case a strip of load is placed upon the wrapping, so as to connect with the armortocarry ofitheinduced currents. When thuscon nected,thearn'1orot' the scctionis united by means ofathin sheetot' lead, h, which is preferably corrugated, to correspond with the corrugationsiofthe sections, the said-sheet 0 being bent into the form of a sleeve having its edges lap-jointed and then soldered. An opening, Z, having a flap, -is formed in the side of the sleeve h, and after the sections have been connected insulating material is filled in 5 through saidopening,einbedding theconnected. ends of the wires, thus insuring thorough insulation. After filling, the flap is closed and soldered,.-'and the union will be complete.v

In so far as-relates to the method of joining too two sections of cables herein shown and de a fead-armoi'edcable, whih consists incutt ing I5 scribed, the same is not herein claimedfbut through thearnlor transversely and longit udi- I Belly asuitabIe .dist-a-nce, Openingthe divided fov'ms the snb ect-mattenof another division of this application.
