About 84 ft. of rope is required to put in a good smooth long splice. The wire ropes employed in ropeways are made of 6 strands of 7 wires each, and a core or heart; as there are two rope ends to splice together, there will consequently be 12 strands to be tucked, in. Operators usually tie the stops that mark the length of rope, about where the centre of the splice will be, In this case the usual way is to unlay each rope up to that point, and .place the strands of rope a between the strands of rope 6, the cores or hearts of the ropes a and 6 being cut off so that the cores of the ropes abut against each other. There will be then 42 ft. of strands each side of the stop, as is shown in L.
It is important that each strand should be in its proper place, so that none of them crosses other strands, or that two strands be not where one strand should bo (by placing your fingers between each other in natural position this will be understood). Then strand No. 1 of rope a is unlaid, and strand No. 1 of rope b fellows close, and is laid snugly and tightly without kink or bend in its place, until within 7 ft. of the end; a temporary seizing is then put on, securing ropes and strands at this point. Strand No. 1 of rope a is then cut off, leaving it 7 ft. long. Then strand No. 2 of rope a is unlaid, and strand 2 of rope b is laid in its place to within 21 ft. of its end. Strand No. 3 of rope, a is unlaid, and strand No. 3 of rope 6 is laid in its place to within 35 ft. of end. By this time you have reached within 7 ft. of the centre, and, reversing the operation, unlay strand No. 4 of rope b, and lay in its place strand No. 4 of rope a, to within 7 ft. of its end; unlay No. 5 of rope 6, and lay in No. 5 of rope a, to within 21 ft. of its end; finally, unlay No. 6 of rope b, and lay in its place No. 6 of rope a, to within 35 ft. of its end.
The strands are now all laid in their places and seized down for the time being, the ends are cut off, as with the first strand, to 7 ft. long, and present the appearance as in M.
The next operation is to tuck in the ends, and we will proceed to tuck in b 1. It will be remembered that the ropes are made of 6 strands, laid around a core or heart, usually of hemp, of the same size. Two clamps N made for this purpose are fastened on the rope so as to enable the operator to untwist the rope sufficiently to open the strands and permit the core to be taken out, which is cut away, leaving a space in the centre of the rope; the strand 6 1 is placed across a 1, and put in the centre of the rope in place of the extracted core, forming, in fact, a new core. A flat-nosed T-shaped needle used in splicing, the point of which is about 1/2 in. wide by 3/16 in. thick, rounded off to an edge, is well adapted to this purpose. The strand b 1 is laid in its entire length, the core being cut off exactly at the extremity of strand 61, so that when the rope is enclosed around the inserted strand, the ends of the strand and core should abut. If there is much space left in the centre of the rope without a core, the rope is liable to lose its proper form, and some of the strands fall in, exposing the projecting strands to undue wear.
The same operation is performed with a 1, running the other way of the rope, and so on, until all the strands are tucked in, which, if properly done, will leave the rope as true and round and as strong as any other part.
Some operators prefer to start from the end of one rope and consequent end of splice. The operation is about the same, but more care has to be used in bringing all the strands to an even tension in the parts spliced.
The diamond hitch, Fig. 341. This is largely used for tying goods to be carried on animals' backs. The pack saddles e may be of the simplest description, resembling small, light sawbucks, with side boards fastened under the crossed pieces, to come upon the animal's back. In saddling, a piece of blanket is first put on, then the saddle is girthed, or, "cinched," on very tightly.
The operation of packing involves the use of the peculiar knot, very famous in its way, termed the " diamond hitch." By its agency the packs are fastened rigidly in position on the back and sides of the animal carrying them. After the animal has been saddled, the packs, divided into two even portions, are slung up, half on each side, by two packers. To the parts of the saddle corresponding to pommel and cantle, short lines are fastened. The packers hold the packs up against each side of the pack animal, and passing the ropes around the articles from undernesth, and up, over, and across the back, tie the cuds together no as to hold all in position. Any small Articles are piled on top, and all is rend; for the diamond hitch.
To make this, a piece of 2 or 3 in. rope is used, about 30 ft. long. One end is fastened to a short girth or cinch d. To the other end of the cinch is secured a large flat hook, generally made of wood. In the army a long leather strap, about 1 in. vide, is used instead of the rope. Throughout the whole operation the packers work in pairs. One stands on the near or left side of the animal, whom we shall designate as A: the other stands on the off or right side, and will be called E. The packing rope and cinch are taken by A on the near side. He swings the hook end of the cinch across under the animal's belly to B, who catches it. Then A makes a bight in the port of the rope near the cinch, and throws it over across the top of the park to H, who inserts it in the hook. Thus two leads of the rope run over the top of the pack transversely. A then turns n half-hitch with a large loop in the next succeeding part of the rope, and passes the free end to B, This end B pastes over the second and under the first lead of the rope lying across the packs, and as near the centre as may be. The state of things at this point is shown in a.
