OF SYRACUSE, NEW YORK, vASSIGrITOBfS 'JIO SE, NEW YORK, A CORPORATION OF NEW nnnc'rmcAL coUrLING.

To al whom 1' may concern Be it known that we, JESSE la. Hmns and Jenn loss'snfr, of- Syracuse, in the county of @nondaga andx State of New York, have invented af certain` new and useful Electrical Coupling, of which tlie following is a specif'lCt-lon'. l

Our invention has for its object the production of an electrical coupling or line tapper, Awhich is particularly simple inconstruction and' highly efficient in use ;"and itconsists in the combinations and: constructions hereinafter set forth andi claimed.

ln describing this invention, reference is had tothe accompanying drawing, in -u'hich like characters designate' cm'responding parts in all the views.v

Figure 1 is a longitudinal sectional-view, partlyin elevation, of this coupling or line tapper, contiguous Portions of conductors being alsofshown. fig. 2" is a vertical sectional view taken at ariglit angle to Fig. 1, parts being omitted.V Fig. 3 is a side elevation of this coupling, the movable division of tlie sleeve or band member being shown in its open position.

Thiscoupling comprises generally a body or main member which normally supports or carries the remaining parts oi the coupling, including, parts' movable relatively thereto, andincludes a threaded stem and a transverselyeextending. sleeve or band member 'at one end of the stem, a movable clamping element carried by' the ste1n.andV having a` headv located within the bore of tlie sleeve member, and a nut turning on the stem and vcoacting with the' movable division of the sleeve member and withl the clamping elementi` 1 is the threaded' stem of the body of the coupling, and 2 andi 3' are divisions of the sleeve orbandme'mberlocatedat one end of the'stem and adapted to 4receive a conductor 4, tlie division 21 being secured" to the stem andthe division 3` beinr hinged; at 5 tothe division 2;- The" body ofthe-coupling -is also provided at its otheriend with attaching means for'connecting the coupling to another object, as asecond conductor 6,'.sa1dattaelnng means' including a' contractile sleeve 7 ar- V'and compresses the end of the body, the sleeve 7 having a conieal periphery which engages a comple-- mental circumferential Walll of the socket 8. rllhe sleeve 7 is forced into the socket- 8, by

means of a nut or'internally threaded sleeve x 9 turning on said other end of the body and having an internal fiange 10A which engages the outer endof'the sleeve 7 and thereby forces said sleeve into the conical socket 8 same upon the conductor (l. The portions of the stem adjoining the sleeve member include two

partcylindrical sections

11 and 12 complemental to each other and connected respectively to the divisions 2. and 5i ot the sleeve member,

one section as 11 being permanently fixed' to v' the. major part of the stem, and the other, ll'being separa-ble therefrom and carried: by the hinged' division El ot the slicevcnrlmber;

13 vis the head of the movable clamping element which also includes a shank 1 4, the' headlfl being. located in the bore of the sleeve member and provided with an arcuatel face l5 for engaging the conductor 4. The

shank 14 extendsmt'o anaxial passage 16 provided in the stem and preferably in the section 111) thereof andI opening through the end face ot such section into the bore of the sleeve member. The clamping elementalso the shank .14', depend' trom the ends of the so. includes lugs 1T which extend'v parallel to head 13 and slide in recesses 1S formed in the meet-ing faces of the

sections

11 and 12, and project laterally on opposite-sides o@ the. stem and the sections thereof, these 're` cesses TS opening through the peripheries-of the sections andA also into the bore of the sleeve member. The recesses 18 are preferably ot less length thanthe' sections 1:1' and 1'2 and shoulders 19, normally en of the lugs 17. Usually, tbe fixed-section of the stem is formed with a part-cylindrical" .Y 95 .I

portion 20 concentric with', but of opposite curvature to, and' of less radius thamthe" provided at their ends with.

raged by the' ends threaded surface oi said fixed section 11, the'- axialpassage 16 being formed' partly in said portion 20, and the separable section 12 is formed with a recess 21fitting said 'partv cylindrical portion 20.

22 is a.' nut turning on the threaded stem and the sections 1l and 12 thereof against the projecting portions of the lugs 17 for:

forcing the clamping element axially of -the stein and thus firmly clamping the conductor 4 in the sleeve member.

The hinge pui 5 connecting the divisions 2 ar-.d 53 lol the sleeve 'member is located at one side of the path of inovement'ofthe head 13 of the clamping eleinentin order that said element may be easily inserted and removed, but in order to prevent accidental f removal of said element when the hinged division 3 is in its outivard position as shown in Fig. 3, the hinge is providedwith means, as a part Q3 fixed, to the division 3 and movable into the path of the head 13, and

the entire length of said element including its stem and head is greater than the distance from the end face of the section 11 to the hinge pin 5, -lVhen the movable parts of the coupling are in their normal position as shown in Figa-2, the

contiguous surfaces

24, and 25 of the hinged division 3 and the fixed section of the stem are continuous so that the upper portion of the head 13 canbe moved outwardly beyond the'hinge pin 5, and thus upon the opening of the hinged division 3, the clamping element can be moved farther outwardly until the shank 4 is disengaged from the stem, but when the division 3 is swung outwardly and the clamping element is in itsnorinal position, thepart Q3 associated With the hinged division 3 projects into the path of the headA 13 of the clamping 4element and thus prevents out-ward move-ment of the` clamping elementJ far enough .to disengage thevshank 14 thereof from the-stem 1 of the coupling.
