JUNCTlON-SLEEVE FOR E LECTRlCAL CONDUCTORS.
1T forming' part of Letters Fatent No. 695,863, dated March 18, 1902.
Application tiled December Si, 1901, b'crial llo. 87,914- (llo modela Be it known that we, THOMAS J. DONOYAN and ERNEST G. ALDERSON, citizens of the United States, residing at Nashville, in the county of Davidson and Stato of Tennessee, have invented new and useful Improvements in Junction-Sleeves for Electrical Conductors, of. which the following` is a specification.
Our invention relates to junction-sleeves for electrical conductors, the same beingpartieularly adapted for use upon underground cables at ihe manholes, where the various conductors in said cables are to be connected one with the other. t also adapted, however, for use upon overhead and other cables.
'lhe object of the invention. is to provide a novel vform of junction-sleeve which will serve to completely house and protect the wires or conductors at their points of con nec- Jfion with each other and which may be readily applied and removed.
Other objects or" the invention will hereinafter appear, and the novel features thereof will be set forth in the claims.
In the drawings ormingapartofthis specification, Figure l is a longitudinal section of a junction-sleeve constructed according` to our invention. Fig. 2 is a similar view showing a slightly-modified construction. Fig. 3 is a cross-section on the line 3 3 of Fig. il. Fig. et is a sectional elevation showing another modilication, and Fig. 5 is an elevation of the device in the act of connecting up the terminals of the conductors.
Like reference-n umerals indicate like parts in the different views.
The body l of our improved junction-sleeve is preferably cylindrical in form and of greater diameter than the cable-terminals which are inserted therein, and the same is provided at its ends with external screw-threads 2 3. These threads may be and preferably are formed upon separate sleeves e 5, which are provided with angular faces for the application of a wrench and are welded, soldered, or otherwise secured to the body l. Adapted to lit upon the ends of the body l are the caps G 7, each of the same being provided with a contracted stem S and with two sets of internal screw-threads 9 lO. The screw-threads 9 in the enlarged portion of each of said caps are adapted to mesh with the screw-threads 2 8 on the body 1, and the screw-threads 10, which extend through the stem S, are adapted to receive the externallyscrew-threaded collars 1l, which are welded, soldered, or otherwise secured to the lead sheathing l2 of the cable-terminals 13 14. The collars ll are provided with extensions ll", having polygonal faces, and are secured to the ends of the sheathing l2; but the conductors of the cable project beyond thc collars, so as to extend into the body l of the junction-sleeve when the parts of the device are in place. ln order to effect this, the sheathing l2 is removed from the ends of the insulated conductors, so as to enable the same to be electrically connected with the conductors in the other cable.
The collars 11 being connected to thc sheathings 12 of the terminals of two cables, our improved junction-sleeve is applied as follows: One or the other or both of the caps G 7 are screwed upon the collars 1l, so that the same are located behind or back of said collars upon the sheathing l2. The same are then free to be moved in one direction or the other. The body l of the junction-sleeve is then placed loosely over that end of the cable which contains the cap G or 7 and moved far enough rearwardly to expose the terminals of the conductors in said cable. These conductors may then be electrically connected with the proper conductors of the adjoining cable in the ordinary manner. The body l is then moved outwardly and screwed up into the cap on said adjoining cable until it reaches the limit oi its movement. The cap on the terminal of therst cable is then screwed onto the open end of the body l, which action at the same time screws the collar ll ontwardly into the stem S. Vhen the latter cap has been screwed up to the proper point to the body l, the connected ends of the various conductors are completely housed and protected within said body and cut off from access of water or other disintegrating agent thereto.
From the foregoing it will have been observed that it is only necessary that one cable end or terminal be provided with a collar ll, which screws into the stem of the cap on ICO the end of the body 1. With one of said cable-terminals provided with said collar the yother may be secured in the cap at the opposite end of the body 1 in any suitable manner. For example, it may be merely passed through the openingin the stem 8 of the cap 7a and cemented in place, as clearly shown in Fig. 2 of the drawings. When this is done, of course the screw-threads in the stem 8a areL dispensed with buta sleeve 15, of insulating material, should be interposed between the cable and the stem of the cap through which it passes.
If it be desired t-o use our improved device at the point of connection of a series ofv cables, we may substitute for one of the caps 6 7 at the end of the body 1 the cap 16, which is provided with a plurality of nipples 17 1S, leadingoutwardly therefrom, communicating with the interior thereof and provided with external screw-threads. Through these nipples the branch cables 19 20-may pass to the interior of the body 1, each of said branch cables being provided with externally-screw- -threaded collars 21 22, similar in all respects to the collars 11, heretofore referred to. The screw-threads on the collars 2l 22 are cut in the opposite direction to those on the nipples 17 and 18, and the same are connected with said nipples by means of the coupling-sleeves 23 24, which are provided with internal screwthreads meshing with the screw-threads on said collars and on said nipples and also provided with external angular faces for the application of a wrench. By turning the couplings 23 2:1. in one direction or the other the cables 19 20 may be locked to or unlocked from the cap 16.
We have shown in the drawings but two nipples 17 18 on the cap 16; but it is obvious that this number may be increased, if desired.
The polygonal faces on the extensions 11 of the collars 11 are provided for the application of a wrench or similar device to prevent the turning of said collars and the stripping of the same from the cable-sheathing when the caps are screwed up thereon. y
Having now described our invention, what we claim as new, and desire to secure by Letters Patent, is-
1. The combination with the terminals of two electrical conductors and an externallyscrew-threaded collar on one of said conductors, of a junction-sleeve comprising a body having screw-threaded ends, and caps screwing upon said ends, one of said conductors bein gsecured to and passing through one of said caps and the other of said caps being provided with an internally-screw-threaded stem into which said collar screws.
2. The combination with the terminals:Y of two electric cables, one of which is provided with acovering or sheathing, and an externally-screw-threaded collar secured to said sheathing, of a junction-sleeve comprising a cylindrical body having screw-threaded ends, and caps adapted to screw upon said ends, one of said cables being secured to and passing through one of said caps to the inside of said body and the other ot' said caps being provided with an internally-screw-threaded stem into which said collar screws.
3. The combination with-a series of electric cables, each of which is provided with a lead covering or sheathing and with'an externallyscrew-threaded collar, of a junction-sleeve comprising a cylindrical body provided with screw-threaded ends, a cap screwing upon one end of said body and provided with an internally-screw-threaded stem into which the collar on one of said cables screws, a cap screwing upon the other end of said body provided with a plurality of externally-screw-threaded nipples thro ugh which the other of said cables pass to the interior of said body, and couplingsleeves having internal right and left hand screwthreads, for connecting said nipples with the collars on the cables which pass therethrough. y
In testimony whereof we have hereunto set our hands in presence of two subscribing wit- IIGSSGS.
