' CABLE-SPLICING JOINT.

Application filed December 1, 1913.

To all whom it may concern:

Be it known that I, DEANE E. BOSTICK, a citizen of the United States, residing at Houston, in the county of Harris and State of Texas, have invented certain new and useful Improvements in Cable-Splicing Joints, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a cable splicing joint and has for its principal object the production of a device for incasing the joined ends of two or more cables and preventing the moisture from entering thereinto.

Another object of the invention is the production of a detachable cap whereby the two or more ends of the cables may be connected after which the cap may be placed in position upon the case thus excluding moisture therefrom.

With these and other objects in view this invention consists of certain novel combinations, constructions and arrangements of parts as will be hereinafter fully described and claim-ed.

In the accompanying drawing :F igure 1 is a side elevation of the cable splicing joint. Fig. 2 is a bottom plan view of the same. Fig. 3 is a section taken on the line 33 of Fig. 2. Fig. 4 is a sectional view of the coupling. Fig. 5 is an enlarged sectional view of a portion of the coupling, cap and clepending neck.

Referring to the accompanying drawing by numerals 1 indicates the casing which is cylindrical in form and which converges at its ends as indicated at 2, thereby forming reduced openings 3 wherethrough pass the armored portion 4 of the cable or cables 5. This cylindrical casing l is provided at its central portion with adepending hollow neck 6 which terminates in a lateral flange 7. The cables 5 are stripped of their armor and extend downwardly through the neck 6. The free ends of the wires in the cables are then joined together in any suitable manner and are then bound with tape or other suitable insulating material 8, thereby insulating the wires from the body of the joint. The elongated hollow cap 9 is then positioned over the wrapping or tape 8 and this cap 9 is held in connection with the neck 6 by means of the connecting washers. The cap 9 is provided at its open end with a circumferential flange 10 whereupon is placed the compressible gasket 11. This gasket 11 Specification of Letters Patent.

is compressed between the flanges 7 and 10 when the coupling is screwed into position for holding the cap upon the neck. The retaining coupling comprises-a pair of sections 12 and 16. The primary section 12 comprises an overhanging portion 13 fitting upon the top edge of the wall 15 and formed upon the body portion of the primary section. The auxiliary portion or section 16 is so formed as to he provided with an externally threaded wall 15 which is adapted to be engaged by the internally threaded portion 14 of the primary section 16. This section 16 is also provided with an overhanging portion 17 for engaging the circumferential flange 10 of the cap 9. When these two sections are threaded into engagement with each other, it will be seen that they will engage the flanges 7 and 10 so as to compress the gaskets 11, thereby forming a moistureproof closure between the cap 9 and the neck 6.

When this device is used, the armored cable or cables are passed through the openings 3 at each end of the casing 1. The cables 4 passing through each opening 3 and the casing 1 are then wrapped by any suitable metal, as shown at 18, thereby forming a moisture-proof connection between the easing 1 and the cables 5. The cables 5 are then stripped of the armor and joined in the manner above described, at which time the cap 9 may be placed in position and held by the coupling.

From the foregoing description it will be seen that a Very simple and efficient cable splicer has been produced whereby the free ends of two or more cables may be connected without any danger of deterioration being caused by moisture entering into the interior of the device. It will also be seen that since the free ends of the cables extend down into the cap they are bound together so as to extend parallel to each other and thereby reducing the danger of the cables pulling apart as the ends extend at right angles to the body portions of the cables, thereby relieving the wires in the cables from all lateral strain.

Having thus described the invention what is claimed as new, is:

In a cable splicing joint, the combination of a casing provided with a neck, said neck having an annular flange extending at right angles thereto, a cap provided with an annular flange, a gasket interposed between said flanges, of a coupling, said coupling comprising a primary section and an auxiliary section, said primary section being positioned upon said neck and carried by the annular flange of said neck, said primary section comprising a circular internally threaded portion, an overhanging portion formed upon said threaded portion, whereby said primary section is substantially L-shaped in cross-section, said auxiliary section comprising a flat circular body, an externally threaded extension formed upon said circular body, whereby said body will extend beyond the planes of the side surfaces of said extension, thereby forming overhanging portions, said extension being of the same length as the breadth of said flanges and gasket, the body of said auxiliary section engaging the flange of said cap and fitting snugly thereagainst, said extension being of the same height and being threaded into engagement with said internally threaded portion of said primary section, whereby said coupling will retain said cap in position, said circular threaded portion of said primary section abutting against the body of said auxiliary section, whereby said coupling will comprise a compact water-tight connection.

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