Splices. — To splice an ordinary transmission rope, wind twine around
the rope the length of the proposed splice, say 6 ft. or more, from each end,
and unlay the strands back to the twine. Then butt the ropes together so
that the untwisted strands will meet opposite each other in pairs. Next,
cut the twine and unlay one strand from one rope end, following it up with
a strand from the other rope end. and leaving about 18 or 20 ins. loose end
on each strand at the meeting point, for sub-splicing. Make the points of
meeting of other pairs of strands sta^sered regularly so no two points will
be opposite. For sub-splicing of each pair ot strands, split each strand,
unlay and interweave, passing the ends through the rope, or tie with ordi-
nary knots. Hammer smooth.

Manila Rope. — (Adapted from C. W. Hunt.*) Manila rope is made
from Manila hemp fibers (inferior in strength to the Italian hemp). In
manufacturing rope, the fibers are first spun into a yam about i in. in diam.
this yam being twisted in a "right-hand ' direction. From 20 to 80 of these
yams, depending on size of rope, are then put together and twisted in a
left-hand" direction, into a strand. In a 3-strand rope three, and in a
4-strand rope four, of these strands are then twisted together, again in a
'*right-hana" direction. Note that when each strand is twisted it tends to
untwist the threads, but later when the strands are twisted together into a
rope, each strand tends to untwist, but to twist up the threads. It is this
opposite twist of the threads and strands that keeps the rope in its proper form .

The durabilitv of Manila rope is quite variable under different uses.
Experience has shown that 4-strand rope is more serviceable than 3-8trand;
it is stronger for the same diameter, wears rounder and smoother, and the
section is much nearer a circle.

The Strenglti and Weight of Manila Rope are given by Mr. Hunt in the
following formulas:

Breaking strength, in pounds — 7160 X (diam in inches)' (1)

— 726 X (circum in inches)* .... (la)

Weight per lineal foot, in potmds — 0. 34 X (diam in inches)' (2)

« 0.0344 X (circum in inches)* (2o)

U.-^ORDAGE, WIRE AND CABLES.



Hence, from (1) and (2) we have:
Breaking strength (lbs.) - 21060 X weight per lineal foot Obs.) (S)

It is to be noted from formula (3) that pound for pound, manila rope is
as strong as steel which has an ultimate tensile strength of 71600 lbs. per
square inch: as a square inch bar of steel weighs 3 . 4 lbs. per lineal foot, aad
21060X3.4-71600 lbs.

* The left-hand figures in the colimin are the weights according to Mr.
Hunt's formula (2), and the right-hand figures are corrections which give
resulting weights in accordance with some of the manufacturers' tables.
The true weights are somewhat approximate and probably lie within the
two limits.

t Calculated from Mr. Hunt's formula. See also table of Breaking
Strength of Manila Rope by Spencer Miller in Eng. News, Dec 6, 1890.

The safe strenph of manila rope given in the above table is based on a
safety factor of 20, which Mr. Hunt recommends for rope driving. The
following working loads are recommended for rapid (400 to 800 feet per
minute), medium (wharf and cargo, hoisting 150 to 300 feet per minute),
and slow (derrick, crane and quarry, speed at 50 to 100 feet per minute)
