SPECIFICATION forming part of, Letters Eaten:- IZc. 782,391, dated February 14, 1905. Application filed March 19, 1-904. Serial No. 199,024.

To It lL'hOHL it may concern:

Be it known that I, ALnnn r P.\RKER HAN 1 sex, a citizen of the United States, residing at which the following is a full, clear, and concise specification.

My invention relates to el .ctriccables, and more particularly to simple and practical forms of construction of the same in the respect of the disposition of the leads or tapsby which the respective conductors thereof are connected to lineacks and other points, the more prominent OlJJQCtS of the invention being economy of space, comparative cheapness of manufacture, and a material saving of transverse tap conductors 2 2, the, which are time required for installation.

The invention also involves other features of importance and advantage, as will hereinafter appear, and be more particnlary pointed out in the claims appended hereto.

In another application, filed by me duly Z, 1902, Serial X0. 115,248, I have shown and described a modification of the principle of my invention specially adaptedfor themultiple contact-points of individual-switch automatic telephone-exchanges. The present application pertains to the broad form of my invention for general use and as a substitute for the complicated cable construction here 'tofore employed.

The invention consists of an arrangement of main cable-conductors folded into or otherwise disposed upon or between a layer or layers of insulating ribbon or sheet material, the layer or layers being perforated or cut away at certain points. so as to leave openings or gaps which permit of the connection of a series of tap-conductors with particular ones of the main conductorsor through which, if desired, the main conductors themselves be looped to form the tap-conductors, as will be hereinafter described.

In the accompanying sheetof drawings, which forms a part of this specification, Figures 1 to 5 are elementary forms of the in vention, illustrating different methods of embodying the same; Fig. 6, a View illustrating in the if the manner of looping the main conductors to constitute tap-conductors; Fig. 7, a view lllllstrading a modification with main conductors disposed in longitudinal tucks, and Fin. n a bank term of the cable.

Rcf'erring'to Figs. 1 to 6, Pircprcscnts a sheet or ribbon. of insulating material. pro-- vided with openings or gaps B. extending diagonally across the same, the latter being:

i ot'slots or apertures or a coming of the ribbon, as shown in Fig". Uponon'c side of the ribbon is disposed a series of main cable conductors 1, running longitudinally of the ribbon and preferably suitably secured. to it by means of shellac, glue, zcuor by embedding or inclosing them in Upon the opposite side is disposed. either in groups or continuously. a series of plete so. a

preterz-ibly also suitably secured to the ribbon A, the conductors of thetwo series bein thus arranged in substantially parallel planes. At the cro. ing-points of the different conductors of the are series of main and tap conductors the latter are electrically connected to the former through the openings or gaps, the connection being eflected either by the contact of one with the other or'by the more permanent means of a drop of solder. The main conductors may manifestly he of any suitable shape and size, being shown in the drawings as ronnd bare wires, and they may be wound around an insulating string core, as indicated in Fig. 5. or provided withv any of the usual appurtenances to electrical conductors designed to lessen the inductive disturbance of one upon the other. The tap-conductors ex.- tend onone or both sides beyond the edges of the ribbon A, and covering ribbons G, of insulating material, may be employed where the Wires are req aired to he further protected. In Fig. 3 is illustrated a form in which the main and tap conductors are separated by separate cross-running strips of insulation A A instead of a continnousribbon, the sheets A being perforated to allow of ,proper connection" through the same as above.

e to 8 one or both of the scparating and protectinglayers A or C are corrugated and the conductors ar disposed in the corrugations, the spertnrcs oeino; provided i J! i as oeiore, but iocst respectively, 1D. the
