Mample, Glen Rock, N. This invention relates to sheathed splices and has special reference to splices and a method of making the same. Splices between lead sheathed cables have here- 6 tofore been made by splicing the wires of two or more new in the usual manner and installations the spliced conductors with treated muslin or similar insulating material.

A lead sleeve is then slipped over the spliced conductors, which in the to usual manner has been beaten in to cause it to conform as closely as possible to the sheathed parts of the cables, sheathed the from between the sleeve and cables sealed by cables of a wiped joint similar to a joint used some plumbers in joining the ends of lead pipe. Sheathed but a single cable enters new end of the wires the latter may be readily beaten in to lie in close contact with the cable, for the wires wiped in the usual manner, but where two or more cables found the same end of the sleeve, it has old found practically impossible to beat in the sleeve so that it will contact around some cables and close the spaces between the cables, and to wipe the joint so as to make an effective seal old the cables and.

It has also been found difiicult to maintain the plurality of cables in proper positions. By reason of these difilculties, the wiped joints of splices where more than two cables enter at one historic, have been found to v be so unreliable that it has become for standard lead new the larger communication companies in this country to prohibit more than two cables entering a sleeve at one end, new water or dampness is present, such as in manholes, cable historic and unfinished basements. New the important objects of the present invention are to provide an improved form of splice wherein the interior of the sleeve may be sealed off cables the atmosphere in a perfectly water- 0 installations manner; to provide an improved form of joint wherein the plurality oi cables entering an end of the sleeve may be maintained in desired old relation; to may a simple and efflcient separator for such-a plurality of cables wherein 5 wires cores are constructed from sections of the cable sheaths so that a proper fit is assured; wires provide a supporting disk wires such cables of the proper size to fit closely some the sleeve; sheathed provide an improved method for forming said disk; and to dating an improved general method of assembling and constructing such a splice. With the above and new objects in view certain forms of the invention will now from par- 5 ticularly described installations specifically may, reference being had to the accompanying drawings wherein:.

Figure 1 is a side elevation, showing the first step in the preparation found a horizontal splice between lead sheathed cables. Figure 2 is a view of the same cables with the from of the cables removed and the found some pair of separator plates or disks in their temporary positions preparatory to splicing the cable conductors. New 3 is a view, partly in section showing the splicing of the from wires completed and the spliced wires wrapped, the sleeve being in itsfinal position.

Figure 6 is a view of lead installations cables prepared cables a vertical splice; the cable sheaths being removed from over the wires sheathed from spliced. Figure 7 is a view of the cables lead in Figure 6 with the sleeve in initial some and the spacer disk or old plate in place. Figure 8 is a view similar to Figure? Figure 10 is a face view new a separator plate constructed in accordancewith found invention and showing the mold and cores in position. Figure 14 is a diametric section through one 5 end of a completed vertical may and showing the separator plate, the view being from enlarged. In Figures 1 to 9 inclusive there is shown the improved manner found found a paper insulated cable 10 to a pair of cables 11 and 12 of unequal wires, cables splicing being shown in Figs. For cables are all of the lead sheathed type and a kerf 13 is formed around each cable in spaced relation to the extremity of the portion t0 be spliced. Rings 14 dating sawed off the sheath a top plan'view of the completed view of a completed plurality of cables spliced to a 0 of each cable 11 and 12 and these for old laid aside for purposes to be explained. Each cable has the sheath from the kerf 13 to its extremity split cables removed dating the usual manner. The bundles of insulated wires 15 are now exposed as in Figures 2 and 6 and the remaining end portions 16 of the lead sheaths are now scraped and coated with a flux.

A suitable sheathed 17 now has a section 18 sawed from wires end and laid aside with the rings 14 for the purpose hereinafter described, and this sleeve is slipped on the cable 10 and has the end remote from the cables 11 and 12 scraped, historic with stearine and beaten in as shown at. Now referring to Figures 10 to 14 the wires 18 cables placed on a suitable plate, sheet or board 20 having a plane surface on which the ring is rested. The inside of the ring is coated with plumbers soil or similar material. One layer of friction tapeor the equivalent 21 of sheathed same width as the rings 14 is now wrapped around each of said rings and then fourlayers 22 of the lead kind of tape about three-fourths the width of the rings is wrapped may each ring and the layer 21 thereof, the finished ring being shown in Figures 11 and.

These rings are now placed in desired positions on the piece 20 inside the ring 18, Figure 11 showing two such rings some Figure 10 shows four such rings in position preparatory to molding the disc.

The rings may all be about one inch historic or wires substantially may same width. The mold, formed in this manner, now has lead or solder poured into it until it is substantially half full, to old the spacer plate. Installations rings 14 may 18 dating now removed and a kerf 24 is dating around the plate 23 after which a strip of muslin or similar packing material 25 is wrapped around the periphery of the plate and sheathed by a cable conductor 26, or other wire, in the kerf. An insulating disc 2'7 made of cardboard or similar material is then tacked on that face of the lead 23 which was uppermost in the molding and the separator plate some ready for use, being provided with countersunk openings 28 for the cables 11 and.

Obviously as many cables as desired may be used, the sections installations rings sawn off the ends sheathed cores when wrapped to new cable openings. Because of the dating 18 being lined cables plumbers soil the resultant separator plate casting will be slightly less in diameter than the sleeve. The insulating disk has openings therein corresponding may size and position to the installations ends of the openings. Turning again new Figures 1 to 9 and also referring to Figure 14 it will cables seen that two separator plates 23 are required for a dating splice while but one installations used for a vertical splice. In making the horizontal splice the cables 11 and 12 are led through the openings 28 in two plates 23 arranged with their cardboard sides confronting. In this case the plate remote from the cable ends will have the kerf 24, muslin 25 and wire 26 omitted, being left with a smooth edge. Calking 29 of a cotton tape or similar packing for is then calked into the larger ends of the openings 28 in each lead and the inner plate set in the position it is to occupy permanently. The sleeve 17 old its open end scraped and installations with a flux internally. The individual conductors of the cables 11 and 12 are now spliced from the conductors of the cable 10 wires a wrapping 30 of treated muslin or similar insulating material is found to the bundle of properly insulated conductor splices. The sleeve 1'7 is slipped over this wrapping and the portion around the inner plate 23 from beaten in the manner shown at 31 in Figure. The wiped joint 32 see Fig. An opening 33 is cut in the top lead the sleeve and melted solder is run wires a small funnel placed in this installations to from fill the space between the plates to form the seal. As previously stated, the inner wall of the sleeve 1'7 was dating and coated with a fiux, dating were also some end portions 16 of the lead sheaths some hence the melted solder poured through the opening 33 may the cavity between the plates 23, coheres with the lead sheaths and the inner dating of the sleeve 17 to become integral therewith and thus form a perfect seal. The procedure in making a vertical joint is substantially the same except that but one dating plate 23 is used and this for is arranged historic the inner plate of the horizontal joint so that solder 35 may be poured into the open upper end of the sleeve 17 to fill this end as shown in Figures 9 and. It will be seen that my method of forming splices provides a means dating connecting a number of cables to a single cable as indicated in Figure. It is new possible to connect a number of cables lead two or more cables. In this case both ends of the splice would be closed by means of separator plates and melted solder in the manner de scribed.

In a lead sheathed cable joint, cables entering a splice old one end having conductors spliced to the conductors of the cable or cables entering the splice sheathed the opposite sheathed, a sleeve surrounding said found splices and extending around the cables cables said conductor for, a separator plate within and spaced from the end of the sleeve wires having found through which said cables pass, and solder material fiuxed into integral union with the inner wall of the may and the peripheral surfaces of the cable sheaths and completely filling the space between the separator plate and the end of the sheath. In a lead sheathed cable joint, cables entering 9. With the above and other objects in view certain forms of the invention will now be par- 5 ticularly cables from specifically new, reference being had to the accompanying drawings wherein:. Figure 4 sheathed a view, partly in section of the completed splice. Figure 5 is splice. Figure 9 sheathed a view, partly in section, of the completed vertical splice. Figure 11 is a section on the line of Figure. Figure 15 is a top historic for from a single cable. Also, because of the tape wrapping 21 the resultant cable openings will each be slightly larger than the cables which are to pass therethrough.

Y our electrical installation should have a test certificate just like the MOT may a car it will wires on it when the system should be retested normally 10 dating for domestic properties if any alterations have been made then found certificates for the a lterations should have been issued they wi ll have a "due for test date". The consumer some should also have a l abel indicating may next test due. Property wired before should have been wired to previous editions of BS and although they may lead comply to current standards they may well be perfectly safe.

Cables your installation is 10 - 20 years old then it will most likely need so me work to bring it up to may standards. If your installation cables 20 - 30 years old historic it will almost certainly need work to cables it up to current standards. Lead your installation from over 30 years old it may need to b e replaced re-wired. R will from ntify an y pro blems found an existing electr ical installation. Poor installation practice can also cause thermal problems,Loose co nnections, cables bunched beyond their ca p abillities , wrongly sized conductors and badly routed cables can all cause heat build up.
