Application filed January 29, 1912. 4 Serial No. 674,648.

1 "0 all whom 1' '15 may concern lie it known that I, HARRY E. ADAMS, a citizen of the l nited States of America, residing at. littsbur'gh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Taps tor Multiple-Conductor Metallic-Sheathed Cables, vo't' which the following is specification.

This invention relates to taps for multiple conduct-ormetallic sheathed cables, the object of the invention being to provide an imtransverse proved device of this character adapted for use when it is desired to tap someof the conductors ota main cable, and to carry branches of these conductors through a branch cable to some other point.

The present invention comprises animproved device of this character constructed in such manner as to constitute av housing, the im'at'a llic sheathing of the main cable forming a portion of the housing.

Further objects and advantages of the invention will be set forth in the detailed description which now follows.

In the accompanying drawing Figure l is a perspective view of a tap eonstiucted in accordance with the invention. Fig. 2 is a vertical sectional view therethrough. Fig. 3 is a detailed perspective view showii'ig the main cable split, as hereinafter described. Fig. 4 is a side elevation of a portion of the tap. Fig. .3 is a side elcvation illustrating the device in use upon a water pipe to term a tap between a main conduit and branch conduits. and Fig. (3 a plan view-.ot the device illustrated in Fig. l. i

Like nmncrals designate corrcspondinoparts in all M the figures O'l': thedrawing.

Referring to the drawing, the numeral 5 designates the metallic sheathing. usually at lead, of a multiple conductor cable, and (S designates the conductors passing therethrough. A housing casting); 7 is provided with a pair of longitudinally entendingrails 8, which are spaced from the housing 7 by ribs 1). This leaves channels 10 between the rails and the housing 7, said channels being open both at the top and at the bottom.

in carrying out the invention. the metallic sheathing 3 is split and thc walls'o't' the sheathing, upon opposite sides ol the split portion. are bent. outwardly as at 1'1 in Figs. 2 and 3. The upper edges of these outwardly bent portions enter the channels 10.

Since. the splitting of the cable opens the top thereof and exposes the wires, it is apparent that any desired number of-the conductors may then be tapped by branch conductors 12 and carried oil to any desired point through an outlet 13 and branch cable 14-. Internally threaded openings 15 are formed in the face of the housing 7 and may be closed when desired by plugs 16. These-openings permit the filling of the interionof the housing with paratlin, or any desired plastic composition, after the proper connections have been made between the branch conductors 12 and the main conductors 6..

To form a fluid and moisture proof joint between the housing 7 and the upper-edges of the walls 11 of the sheathing, solder indicated' at 17 in Fig. 2, is poured into the channels 10. This seals the housing along its sides. To seal the housing member 7' to the cable at its ends, saddles 1.8 are supported by ribs 15) from the housing-and the upper faces of these saddles are cut. away at 21 "for the reception of molten solder, which, when poured into recesses 21 seals the ends o'f'the housing to the cable. 'T his tap may, if desired, be employed for the purpose of connecting the branch water pipes to water mains, and such a structure has con-illustrated in Fig. 5, wherein numeral 5 designates the main water pipe and (3 designates the housing. The structure otherwise the same as that shown in Fig. 2, and the method of connecting the housing G t the pipe o is the same. In this case, 23 designates branch water pipes which may be conncctcd to the upper portion of the housing in place ot the plugs 1b. At this time it is apparent that a tluid tight joint is made between the housing ti and the main 5, and that water may be conducted through these pipes to any desired point. This is particularly znlvantagcous where it is desired to connect a plurality of laundry tubs. tor in stance. toithc water main, these tubs being located elosecnough together to render it desirable to talre, oil a plurality of branch pipes at adjacent" points. For this latter purpose, the structure herein described is entirely etlicient.

From the foregoing description it will be seen that simple and etlieient means are herein provided for accomplishing the objects of the invention, but while the elements shown and described are well adapted to serve the purposes tor which they are in.-

tendedfit is to be understood that the'invention'j'isnot liniitedxto othe precise construction set forth, but includes within its. purview, such changestas may be made with -1n' the scopeof the appended claims.

Having described my invention, what I -1 In a device of the character described, the combination with a'conduit split longitudinally and having its walls bent out- ,Wai'dly u'p'on" opposite sides of said split .port-iomoj a housing member having a 10ngitndinally extending channel formed theren up'oniopposite sides, said channel being open both at the top and at the bot-tonuand .inwhich channels'the upper'edges of the .bent out. portions of the conduit enter.

21111 a device of the character described,

the combination with a conduit split longiboth at the top and at the bottom, in which channels the upper edges of the bent out portions of the conduit enter, and a fusible sealing filling for said channel for sealing the housing to the conduit.

3. In a device of the character described,

the combination with a conduit split longitudinally extending channel formed therein upon opposite sides, said channel being open both at the top and at the bottom, in which channels the upper edges of the bent out I portions of the conduit enter, and a fusible sealing filling; for said channel for sealing the'housing to the conduit, there being an opening formed in said housing member and a closure for said opening.

' 4. In a device of the character described, the combination with a conduit split longitudinally, and having the material thereof bent outwardly upon onnosite sides of said split portion, of a housing member open. at the bottom and having channels formed in its opposite lower edges which are open both at the top and at the bottom and in which channels the upper edges ot' the bent out portions of the conduit enter.

In testimony whereof I aflix my signature in presence of two witnesses.
