JESSE L. HINDS AND JOHN J. DOSSERT 0F SYRACUSE, NEW YORK, ASSIGNORS TO CROUSE-HINDS COMPANY, OF SYRACUSE, NEW YORK, A. CORPORATION OF NEW YORK.
ELECTRICAL COUPLING.
Application filed October 5, 1910.
To all whom it may com-pro:
Be it known that we, Jnssn L. HINDS and J onx J. Dossnn'r, of Syracuse, in the county of Onondaga and State of New York, have invented a certain new and useful Electrical Coupling, of which the following is a specification.
Our invention has for its object the production of a particularly simple and etlicicnt electrical coupling or line tapper, and
of one section of the stem from the other.
Fig. 3 is a vertical section of this coupling or line tapper. parts being omitted. and the hinged division of the sleeve being shown as swung outwardly. Fig. is a detail view of the clamping element of the coupling.
1 is the threaded stem of the body of this coupling or line tapper. the body also including a sleeve or band member 2 at one end of the stem for receiving a conductor 3. The stem is usually formed with a socket 4 at its opposite end in which means as a contractile sleeve 5 is arranged for holding a second conductor (3, the contractile sleeve 5 having a tapered or conical periphery which his the complemcntal circumferential wall of the socket.
7 is a nut or internally threaded sleeve turning on the lower end of the stem. and having an inwardly extending flange which engages the outer end of the sleeve 5 for forcing said sleeve into the socket 4 as the nut is turned onto the body or stem and thereby compresses the contractile sleeve on the conductor (3.
The portions of the stem 1 adjoining the sleeve member '3 comprises two part-cyliinlrical sections 2 it) complcmental to each other. the section 9 being separable from the section ll), and the sleeve member comprises two divisions. one as 11 being hinged at 1;
3 to the other or fixed division which i in- Specification of U tters Patent.

Serial No. 585,383.
ably carried by, and formed integral with, the
hinged division 11 of the sleeve member. The division 11 of the sleeve member and the separable section 9 may be moved outwardl; into the position shown in Fig. 3 from the position occupied in Fig. 2, in order to permit the conductor 3 to be inserted in the sleeve or band member.
13 is the head of a clamping element or jaw extending into thebore of the sleeve member 2 and having an arcua'te face 14 extending lengthwise of the sleeve member for engaging the conductor 8 therein, said ele ment also having a shank l5 slidable in a transverse slot or passage formed in the stem or the sections 9, 10 thereof and arranged parallel to the axis of the sleeve member. As here illustrated one of the sections of the stem here shown as the fixed section 10 is formed with a recess 16 in its face opposed to the separable section 9, this recess 16 opening through the periphery of the stem and also into the bore of the sleeve member 2 and being widened at its ends, and the separable section 9 is also formed with a compleniental recess 17, the two recesses 16 17 constituting the transverse slot in which is guided the shank 15 of the jaw or clamping element. The head 13 of the jaw extends full length of the sleeve or band member and said shank 15 extends the entire length of the head 13 of the clamping element and is provided with enlarged portions 18 at its ends which fit the widened portions of the recess It). said enlarged portions 18 project mg beyond opposite sides of the stem, and owing to the formation of the enlarged end portions 18 for fitting the widened ends of the recess it). the shank is Hat on the side thereof engaging the wall of the recess 17. Said shank is provided with a groovelocated in its opposite side between the portions 18. The shank is also formed with a slot l9 located in the thinner portion between its enlarged ends 15. the slot extending in a direction lengthwise of the stemiand a fastening element as a screw 20 extends through the slot for se uring the clamping element to one of the sections of the stem so that said element will not become detached when the hinged division ll of the sleeve member is swung outwardly to permit the insertion of the conductor Preferably the clamping element is secured to the fixed section of the stem 18 of the shank of the clamping element for forcing said element lengthwise of the stem '1 so that the head 13 moves radially of the bore of the sleeve member and compresses or clamps the conductor 3.
