METHOD OF SPLICING WIRE CABLES- f ne. 856,493.

Specification of Letters Patent.

Patented June 11, 1907.

Appiimiou inea october 22,1906. serial No. 340,043.

To all 'wi/1,0m, it may concern:

Be it known that I, FLoluo SEPERAK, a citizen of the United States, residing at Lead,

in the county of Lawrence and State of South 'have a righ-t hand twist, the second a left hand twist, the third a right hand twist, and so on throughout the width of the flat wire cable. Each strand of each cable is 'formed of a center or core wire and six outside wires, and the wires of each strand are twisted together in a direction the opposite of that `in which the several strands are twisted together to form a cable.

In case of breakage or where a cable is lengthened by splicing on another section, it is found extremely di'l'licult to form a splice which will not increase the cross sectional area of the cable at any point, owing to the fact that the round wire cables are in parallel relation instead of being twisted to form a round cable as usual, and at the splicing point the various parts which go to make up the entire cable cannot be interlaced in the same manner as they are in a cable circular in cross section.

These and other dil'liculties are overcome by the improved method of splicing Hat wire cables, hereinafter described and claimed.

In the accompanying drawings z-Figure 1 is a View of a portion of the l'lat wire cable indicating the points at which the splice has been made. Fig. 2 is a transverse sectional view through a portion of the cableshowing the method of sewing the cable together latwise. Fig. 3 is a detail perspective view of one of the strands showing the method of splicing the wires of which the strand is formed.

The fiat wire cable is formed of'a number of round wire cables, four of which, designatedfgenerally 1, 2, 3 and 1, are shown in wire cables is Al'ormed of four strands 5 without any center core. The strands ol cables numbered 1 and 3 have a right hand twist, and the strands of cables '.3 and 4 have a le'lit hand twist, and a'liter all of the cables are laid together side by side they are stitched together by cross wires 6 which may be lormed o'l a strand opened out, or a number of wires arranged together in parallel relation in any suitable manner. The sewing strand is passed directly across the cables, two strands on each cable being above the sewing strand, and the remaining two strands of each cable being below said. sewing strand. Where the sewing strand is brought to the outer edge ol the llat cable, it is carried along a short distance, and alter passing over one of the strands ol the edge cable, is again 'forced through the entire series of round cables, as clearly shown in Fig. 1.

Vhere the cable has been broken, or it is desired to lengthen the same, the sewing strands are severed in order that the several round cables may be opened out for a considerable distance. The vfour strands of each wire cable are also untwisted, and opened out, and then the seven wires of each strand are opened out. The wires of each strand are then cut to dil'l'erent lengths, after which the ends of the main cable 6 to be united are brought together, and the splicing proceeds. The seven wires of each strand ol one section of the cable are separately spliced to the seven wires of each strand of the other section, the splicing points or terminals of the wires being arranged at dillerent points, respectively, in the lengths ol the strands, so that the splicing is distributed over a very large area, and there can be no undue increase in the cross sectional area oll the cable at any one point,

The splicing of each strand is carried on in the manner familiarly known as long splicing, wherein the ends of the` wires are cut dilvferent lengths after laying back, and the shortest wire of one strand is brought adjacent to the longest wire of the other strand, and the ends after crossing are tucked under adjacent wires, so that they may be firmly held when tensional strain is exerted on the cable. After all ol the individual strand have been spliced together, the strands of each of the round cables are twisted together and then the round cables are united the present instance, and each of these round by the sewing or stitching wires in order that IOO they may be held'out in the forni of a flat cable.

I claim That method of splicing flat Wire Cables 5 Which consists in opening out the several round cables` of Which the cable is formed, separating the strands of each round cable, opening the Wires of Which each strand is composed, and connecting the Wires of meet- Io ing strands by long Splicing at such points that no two splees are n line transversely of the cable, twisting the strands to form the round cables, and then Sewing the round oables together.

In testimony that I claim the foregoing as I 5 my own, I have hereto affixed my signature in the presence of tWo Witnesses.

FLORIO SEPERAK.
