Knots in Rope
The word "knot" comes from O.E. cnotta, from a Teutonic stem
knutt; cf. " knit," and German knoten; it refers here to an
intertwined loop of rope, cord, string or other flexible
material, used to fasten two such ropes, etc, to one another,
or to another object.
[Other uses of the word "knot": The word is also used
for the distance-marks on a log-line, and hence as the
equivalent of a nautical mile, and for any hard mass,
resembling a knot drawn tight, especially one formed in the
trunk of a tree at the place of insertion of a branch. Knots in
wood are the remains of dead branches which have become buried
in the wood of the trunk or branch on which they were borne.
When a branch dies down or is broken off, the dead stump
becomes grown over by a healing tissue, and, as the stem which
bears it increases in thickness, gradually buried in the newer
wood. When a section is made of the stem the dead stump appears
in the section as a knot; thus in a board it forms a circular
piece of wood, liable to fall out and leave a " knot-hole." "
Knot " or " knob " is an architectural term for a bunch of
flowers, leaves or other ornamentation carved on a corbel or on
a boss. The word is also applied figuratively to any intricate
problem, hard to disentangle, a use stereotyped in the
proverbial " Gordian knot," which, according to the tradition,
was cut by Alexander the Great.]
Knots, Bends, Hitches, Splices and
Seizings are all ways of fastening cords or ropes, either to
some other object such as a spar, or a ring, or to one another.
The "knot" is formed to make a knob on a rope, generally at the
extremity, and by untwisting the strands at the end and weaving
them together. But it may be made by turning the rope on itself
through a loop, as for instance, the "overhand knot", a "bend",
(from the same root as " bind "), and a "hitch" (an O.E. word),
are ways of fastening or tying ropes together, as in the
"Carrick bend", or around spars as the "Rolling Hitch". A
"splice" (from the same root as "split") is made by untwisting
two rope ends and weaving them together. A "seizing" (Fr.
saisir) is made by fastening two spars to one another by a
rope, or two ropes by a third, or by using one rope to make a
loop on another. The use of the words is often arbitrary. There
is, for instance, a knot called the Fisherman's Bend that is
actually a Hitch.
Speaking generally, the Knot and the Seizing are meant to be
permanent, and must be unwoven in order to be unfastened, while
the Bend and Hitch can be undone at once by pulling the ropes
in the reverse direction from that in which they are meant to
hold. Yet the Reef Knot can be cast loose with ease, and is
wholly different in principle, for instance, from the Diamond
Knot. These various forms of fastening are employed in many
kinds of industry, as for example in scaffolding, as well as in
seamanship. The governing principle is that the strain which
pulls against them shall draw them tighter. The ordinary "knots
and splices" are described in every book on seamanship.
The Overhand Knot is the simplest of all knots and is used
at the end of ropes to prevent their unreeving and as the
commencement of other knots.
Figure-of-Eight Knot is used only to prevent ropes from
unreeving; it forms a large knob.
Reef Knot is formed by left over right then right over left.
If it is formed by right over left then right over left again,
a granny knot would be formed. This knot is so named from being
used in tying the reef-points of a sail.
Bowline is a most useful knot employed to form a loop which
will not slip. Running bowlines are formed by making a bowline
round its own standing part. It is the most common and
convenient temporary running noose.
Bowline on a Bight is a double loop and forms a convenient
and comfortable sling for a man.
Sheet Bend is used for bending small sheets to the clews of
sails, which present bights ready for the hitch. An ordinary
net is composed of a series of sheet bends.
