MULTIPLE-WIRE CONNECTOR.

To all whom it may concern:

Be it known that I, VERLIN PAUL GRIN- DLE, a citizen of the United States, residing at Lincoln, in the county of Lancaster and State of Nebraska, have invented certain new and useful Improvements in Multiple- Wire Connectors, of which the following is a specification.

This invention relates to a multiple wire connector, and more particularly to that class of connectors which would accommodate armored wire, especially that class known as B..X.

The object of this invention is to construct a connector in such a manner that more than one B. X. armored wire can be laid to a switch-box, plate, cut-out cabinets, etc., through one connector, instead of having to use a separate connector for each of said armored wires, thereby effecting great saving in time and material in 'the installation of such apparatus.

In the accompanying drawings Figure 1 is a top plan view of the connector showing the armored wire leading thereto; v

Fig. 2 is a transverse vertical section on line 22 of Fi 1; J

Fig. 3 is a iOllZOlltfil section taken on line 33 of Fig. 2; and

Figs. 4 and 5 are views showing modified forms of the connector. 4

A, indicates a multiple connector which may be made of any suitable material, pref erably some material which is somewhat pliable, for instance malleable iron, or the like. The hollow body portion 1 has leading thereto, from one end of the casing, parallel inlets 2 and 3, which are adapted to receive sets of electrical wires 4. and 5 covered with the so-called B. X. armor. These inlets are of such a size as to receive the armor. The opposing wall portions of the inlets 2 and 3 are brought together somewhat as shown in Fig. 2 to more completely surround the armor, and are drawn together by an adjusting screw 6 to more securely hold the armor within the connector.

The opposite end 7 of the connector ter- Specification of Letters Patent.

minates in a single circular opening, which provides an outlet for the sets of wires carried' by the two armored leads. The end 7 is externally screw-threaded, and provided at its base with a shoulder 8.. This shoulder limits the insertion of the end 7 into the apparatus to which it is to be applied, the connector being held therein by suitable lock-nut 9 received upon the screwthreaded end 7 of, the connector.

In Figs. {l and 5, I have shown two modified forms, which show a possible construction when making the connector of such metal as would not be so pliable as themalleable iron.

In these instances, the parallel inlets 2 and 3 and 3 are provided with dividing walls 10,, while the adjusting screws 6 are arranged in the outer walls of the casing, as clearly shown.

It will thus be seen that I have devised a connector which is particularly adapted for use in connection wlth B. X. armored wires or similar armored wires, which is comparatively inexpensive, and yet'particularly adapted for the special use for which it is designed. I

I claim:

1. A connector comprisin a hollow body portion, formed with paral e1 inlets at one end, the opposite wall portions of said inlet being curved inwardly toward each other, means arranged between said inlets for drawing said wall portions together, and a single outlet at the other end of the connector.

2. A connector comprising a hollow body portion, formed with parallel inlets at one end, the opposite wall portions. of said inlet being curved inwardly toward each other, means arranged between said inlets for drawing said wall portions together, and a single outlet at the other end of the connector, said outlet being externally screwthreaded, shouldered, and provided with a lock-nut whereby said connector can be held securely in place.

3. A one-piece connector comprising a hollow body portion formed with parallel inlets at one end, the opposing walls of with a locknut, whereby the connector may which are provided with means arranged bebe securely held in place.
