MONTRAVILLE M. VOOD, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF TO THE CENTRAL UNION BRASS COMPANY, OF ST. LOUIS, MISSOURI.

SPLECER FOR TROLLEY OR OTHER WIRES.

SPECIFICATION forming part of Letters Patent No. 622,747, dated April 1 1, 1899. Application tiled November `Z, 1898. Serial No. 695,284. (No model.)

To all whom it may concern.-

Be it known that I, MONTRAVILLE M. VOOD, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Splicer for Trolley or other Wires, of which the following is a specification.

This invention relates to splicers for trolley and other wires.

ro The object of the invention is to provide a splicer of simple and improved construction and economical in manufacture wherein abutting ends of trolley or other wires and the like may be suitably, conveniently, and efficiently i5 coupled, wherein the coupling-joint is protected from dust, dirt, water, or other matter, and wherein efficient electrical contact is secured.

Other objects of the invention will appear 2o more fully hereinafter.

The inventiony consists, substantially, in the contsruction, combination, location, and arrangement of parts, all aswill be more fully hereinafter set forth, as shown in the accomz 5 panying drawings, and finally specifically pointed out in the appended claims.

Referring to the accompanying drawings and to the various views and reference-signs appearing thereon, Figure 1 is a View in cen-- 3o tral longitudinal section of a splicer embodying the principles of my invention. Fig. 2 is a transverse sectional View of the same on the line 2 2, Fig. l, looking in the directionof the arrows. Fig. 3 is a transverse sectional view of the same on the line 3 3, Fig. l, looking in the direction of the arrows. Fig. 4 is a detached detail side View of the splicer-cap. Fig. 5 is a central longitudinal sectional'view of the same. Fig. 6 is a detail View, in side 4o elevation, of the two parts of the splicer-casin g detached from each other. Fig. 7 is a view in longitudinal section of one of the parts of the splicer-casing. Figs. 8 and 9 are modified 'forms of the invention.

The same part is designated by the same reference-sign wherever it occurs throughout the several views.

In carrying out my invention it is my purpose to provide a splicer specially adapted for 5o use as an emergency splicer for trolley-Wires, but the principles of which are equally well adapted for use in other relations, and wherein in the case of the use thereof as a trolleywire splicer the construction is but slightly larger than the Wires to be sliced and which is neatly finished, so as to offer no obstruction to the passage of the trolley-wheel therealong. To this end I provide a casing, preferably formed in two sections A B, of suitable conducting material. Each of these parts of 6o the casing comprises an extended tubular sleeve, preferably tapered toward the outer ends thereof both exteriorly and interiorly, so that at the outer ends thereof the internal diameter of such sleeves is just largeenough to permit the free entrance therethrough ofl the ends of the trolley or other wires C to be spliced or joined. The sections A B of the casing may be detachably joined together in any suitable or convenient manner at their 7o inner or abutting ends. In the particular form shown, to which, however, the invention is not limitedor restricted, the proximate end of each section AB is interiorly threaded, as indicated at D, Fig. 7,'said interior threads 75 adapted to be screwed upon the exterior threads of a sleeve E, Fig. 1, until the ends of the sections A B abut against each other, as shown in Fig. 1. By this construction it will be readily seen that the two sections of 8o the casing may be readily, easily, and with facility detached or separated from each other.

Reference-sign F designates what I shalll term the splicer-cap. Preferably, and as shown, thiscap is made of suitable metal- `85 such, for instance, as steel-and is closed at one end and slightly tapered from the closed end toward the open end thereof, as clearly shown in Figs.r 4: and 5. Preferably, and as shown, this cap is slitted in the sides thereof, 9o as indicated at G. The internal diameter of this cap is preferably made very slightly smaller than the external diameter of the ends of the trolley or other wire to be spliced for a purpose presently to be more fully explained. If desired, and as shown at H, Fig. 5, the internal surface of cap F may be suitably scored,

grooved, or roughened in order to eXerta more efficient gripping action upon the end of the trolley or other wire to be spliced.

The operation of the invention is as followsa A splicer-cap F is introduced into the larger open end of each section A B of the splicer-v ends of the sections of casing, respectively.

The end of the trolley or other Wire is then inserted in the smaller or reduced end of th'e section of casing.l When this end engages the open reduced end of the splicer-cap by reason of such Wire being of slightly-larger external diameter than the internal diameter of the end of the splicer-cap, as above explained, the split jaws of said cap are slightly forced apart when pressure endwise of the wire to force it into the casing is exerted, thus enabling the end of the wire to be forced into the cap, whereupon the spring-jaws of the cap tightly grip and clamp down upon the end of the wire. The two sections of the splicer may then be suitably joined togetheras, for instance, by screwing the same up upon threaded sleeve E. Now when a separating strain is exerted upon the trolley or oth er wire in a direction tending to draw said wires apart-that is, out of the sections of casingby reason of the gripping of the -caps F upon the ends of the wires said caps are 'carried along-with the wires until the external conical surface of said caps engage the internal tapering conical surface of the casing-section, whereupon the separating strain exerted upon the ends of the wires serves only to clamp the splicer-caps down upon the ends of the wires more firmly.

Thus it will be seen that I provide Aan exceedingly simple and efficient splicer for trol? ley or other wires wherein efficient electrical connection is provided for, and by employing the caps F with solid ends it will be seen that dirt, moisture, or other matter which would tend to impair the efficiency of the electrical contact is wholly excluded from the joint.

Of course it is obvious that the caps may be inserted in the enlarged ends of the casing-sections and the sections assembled by screwing the same together or otherwise as; sembling the same before the ends of the wire to be spliced or connected together are inserted in the ends of the casing-sections.

Another advantage resulting from the use of a cap having asolid end is that when the end of the wire is inserted in the cap it abuts against the solid wall of the cap, and hence by exerting pressure lengthwise of the wire the cap may be unseated from its conical seat in the casing, thus enabling the splicer to be readily and easily removed when required.

In order to increase the efficiency of the electrical connection between the two sections of casing, I may, if desired, arrange a spring J within sleeve E with the respective ends thereof bearing against the solid .heads4 of the splicer-caps F. This spring also serves the purpose of maintaining the caps yieldingly seated in the conical bore of j the sections of casing,`so that when the ends of the wire to be joined are inserted in the ends of the casing yielding opposition is encountered by reason of such spring, the acting of such spring assisting the automatic gripping action of the caps upon the ends of the wire.

While, as above stated, myinvention is-particularly adapted for usevas an emergency splicer for trolley-wires, it is to be understood that the principles of the invention are equally well adapted for use in other relations. It is also obvious that many variations and changes in the details of construction and arrangement would readily suggest themselves to persons skilled in, the art and still fall within the spirit and scope of myinvention. I do not desire, therefore, to be limited or restricted to the exact details shown and'described; but,

Having now set forth the object and nature A of my invention and a form of construction embodying the same and having explained the function and mode of operation thereof, what I claim as new and useful and of my own invention, and desire to secure by Letters Patent of the United States, is-

l.
