HITCHES

The knots so far described are used mainly for fastening rope ends

together or for ending a rope. A quite different class of knots is that

used for fastening a rope to a stationary or solid object. This type of

knots is known as hitches.

Hitches as well as other types of knots should be easily made, should

not slip under strains and should be easily untied. If all ropes

were the same size and stiffness it would be possible to select two

or three knots which would meet all requirements. But, since this is

not true and since a knot suitable for a silken fish line will not be

satisfactory for a ship’s hawser, we find a great variety of knots,

each of which is designed to meet some special requirements of service.

The following illustrations show a variety of the most typical and

useful knots used on fiber or manila rope.

Fig. 49. The Half-hitch is good only for temporary fastenings where

pull is continuous. It is usually used as part of a more elaborate

hitch.

Fig. 50. The Timber-hitch is very similar to the Half-hitch but is much

more permanent and secure. Instead of the end being passed under the

standing part once it is wound around the standing part three or four

times as shown.

[Illustration: _Fig. 49; Fig. 50; Fig. 51; Fig. 52_]

Fig. 51. The Clove, or Builder’s-hitch, is more secure than either of

the above hitches. It will hold fast on a smooth timber and is used

extensively by builders for fastening the staging to upright posts. It

will hold without slipping on wet timber. It is also used to make the

scaffold hitch.

Fig. 52. The Rolling-hitch is made by wrapping the rope three or four

times around the object to which it is to be fastened and then making

two half-hitches around the standing part of the rope. It is then drawn

tight. This hitch is easily and quickly made and is very secure.

Fig. 53. This illustrates another type of Rolling-hitch very similar to

the above but which is not as secure under a heavy strain.

[Illustration: _Fig. 53; Fig. 54_]

Fig. 54. The Snubbing-hitch is made by passing the rope around the

object to which it is desired to fasten it, and then making what is

known as a Taut-line hitch, Figure 68, about the standing part of the

rope.

[Illustration: _Fig. 55; Fig. 56_]

Fig. 55. Timber-hitch and Half-hitch is a combination of the two

separate hitches shown in Fig. 49 and Fig 50. It is more secure than

either used alone.

Fig. 56. The Chain-hitch is a combination of the above hitch and two

or more half-hitches. It is used for hauling in a larger rope or cable

with a tow line, etc.

Fig. 57. The Twist-hitch is more secure than the Half-hitch and it is

suitable only where the strain is continuous.

Fig. 58. Twist-and-bow-hitch is similar to the Simple Twist-hitch but

is easier to untie.

[Illustration: _Fig. 57; Fig. 58; Fig. 59; Fig. 60; Fig. 61_]

Fig. 59. The Blackwall-hitch is widely used as illustrated. The greater

the strain the more securely it holds, but it is unreliable if the rope

is slack. This hitch can be used with chain as well as rope.

Fig. 60. The Lark’s-head with toggle is easily made and is

used as a rule where it is desired to have a type of hitch which is

easily and quickly released.

Fig. 61. Round-turn-and-half-hitch is suitable for a more or

less permanent method of attaching a rope to a ring. Whipping the

end to the standing part of the rope makes it quite permanent.

[Illustration: _Fig. 62; Fig. 63; Fig. 64; Fig. 65; Fig. 66_]

Fig. 62. The Fisherman’s hitch is used for fastening large ropes or

lines to rings and is very similar to the hitch shown in Fig. 61. It is

improved by whipping the free end to the standing part.

Fig. 63. The Cat’s-paw-hitch is suitable for attaching a hook to the

middle part of a rope where the ends are not free. Strain may be taken

on either or both ends. It is easily released.

Fig. 64. The Slippery-hitch is easily made, but has the objection that

it draws very tight under strain, making it hard to untie.

Fig. 65. The Double Blackwall is similar to the Single Blackwall and is

used for the same purpose.

Fig. 66. The Slip Knot and Half-hitch constitute a combination that

is used for the same purpose as the Flemish loop. It is made by first

tying a slip knot so that it will run on the short end of the rope.

Then complete by tying a half hitch with the short end as shown.

[Illustration: _Fig. 67; Fig. 68_]

Fig. 67. The Fisherman’s-bend is similar to the Fisherman’s-hitch

except that the half hitches are replaced with whipping.

Fig. 68. A Taut-line-hitch is used for attaching a rope to another rope

already under strain, where no slack is available for making any other

hitch. It is not secure unless pulled very tight. A few threads of hemp

or marlin served about the taut line for the knot to pull against will

improve the hitch.

[Illustration: _Fig. 69; Fig. 70; Fig. 71; Fig. 72_]

Fig. 69. The Jam Hitch is used in tying up light packages, such as

bundles of lath, small boxes, rolls of paper, and the like. It is a

hitch that will slide along a cord in one direction, but will jam

and hold against moving the other way and will be found exceedingly

convenient. The Jam Hitch will answer the requirements provided the

cord is large enough and of not too hard a body nor too smooth a

surface.

Fig. 70. The Scaffold-hitch is very useful for slinging a scaffold so

that it will not turn in the sling. It is started by making a Clove

hitch with the two free ends of the rope below the scaffold. Then draw

each rope back on itself and up over opposite sides of the board, where

the short end is joined to the other with a bowline. Plenty of slack in

the Clove will make it possible to draw the bight of each end out to

the edge of the scaffold as shown in the left of the figure. The two

illustrations at the right of the figure show another method of making

a Scaffold hitch. Wrap the rope around the scaffold plank so that it

crosses the top of the plank three times. Pull the middle loop as shown

by the arrow and fold it down over the end of the plank, resulting as

shown in the illustration immediately to the left of the arrow. This

is completed by attaching the free end to the standing part with a

bowline. Both hitches are equally good.

Fig. 71. The Studding-sail-bend is frequently employed on shipboard for

attaching a rope or line to a spar.

Fig. 72. The Midshipman’s-hitch is somewhat similar to the Snubbing

hitch shown in Figure 54, but is perhaps a little easier to make if the

rope is under a strain while being tied.

[Illustration: _Fig. 73; Fig. 74; Fig. 75; Fig. 76_]

Fig. 73. A Bale-sling as shown is useful where it is necessary to hoist

an object to which it is difficult to attach the hoisting tackle. It

may be used on bales, sacks, kegs, etc.

Fig. 74. The Hamburger hitch is useful in connection with a bale sling

which is too long for the object it is carrying. It is also used to

balance the load where two slings are used. The sling is placed around

the load as in Fig. 73. Then with the loop end of the sling form a

second loop as shown. Where the two ropes cross start to tie a square

or Reef knot. Draw up the loops as shown, resulting in the Hamburger

hitch. This may be adjusted by running the knot up or down the rope

while slack, but it will not slip under strain.

Fig. 75. Sling for a cask, head up, is very useful where it is desired

to hoist an open barrel of water or lime or other material. Tie an

ordinary knot over the barrel lengthwise. Then separate the two ropes

in the middle of the twisted part and drop them over the head of the

cask or barrel. Fasten the two rope ends together above the barrel as

shown with a bowline.

Fig. 76. A Well Pipe Hitch is used in hoisting pipe, where no special

clamp is available for attaching the hoisting tackle to the pipe. The

hitch shown will pull tighter, the harder the strain, and is also easy

to untie. Pull up all slack possible in the coils when forming the

hitch, in order to prevent slipping when the strain is first applied.

[Illustration: _Fig. 77_]

Fig. 77. The Hackamore hitch is commonly known and used as an emergency

rope bridle or halter, in the western part of the United States. Among

sailors it is known as a running turk’s head, and it may be used in

carrying a jug or other vessel of similar shape. When used for a halter

about twenty feet will be required. The knot is started by forming a

bight in the center of the rope. Proceed as indicated in the successive

illustrations shown. The result will be a running turk’s head. Draw

together the two center ropes forming a bridle complete with bit,

nose piece, head piece and reins. Such a bridle is not suitable for

continuous use, to be sure, but it will be found useful in an emergency.

Fig. 78. The Halter Tie is a knot preferred by some persons for use in

hitching or in tying the halter rope in the stall. If properly set,

it is secure and may be used in some cases in place of the underhand

bowline knot. The halter tie should never be used around a horse’s

neck, because if the tie is not set up correctly it forms a slip knot

and its use might result in strangulation of the animal. In completing

the tie draw the end through and set the knot by pulling first on the

short end. This is important. If the long rope is pulled first and the

kinks in it are straightened out, the tie forms a slip knot, being

simply two half hitches around the rope.

Fig. 79. Horse-hitch or tie is commonly used by farmers and stockmen

to tie a horse or cow with a rope, so it will not choke itself. Tie

an overhand knot in the standing part of the rope and leave open. Tie

another overhand knot or a Stevedore knot in the end of the rope. Loop

the rope around the animal’s neck and insert the knotted end through

the open Overhand knot. This hitch will not slip and choke the animal.

[Illustration: _Fig. 78; Fig. 79; Fig. 80; Fig. 81_]

Fig. 80. The Manger tie is used for tying a horse or other animal to

a manger or stanchion or hitching rack. The end of the halter rope is

first passed through the hole in the manger with a bight or loop on the

free end of the rope, tie a slip knot on the standing part. Stick the

free end of the rope through the loop or bow as shown. This knot is

easily and quickly tied, but under great strain will pull tight, making

it hard to untie.

Fig. 81. The Figure Eight Manger Tie is superior to the ordinary Manger

Tie in that it will not pull tight under heavy strain such as would

occur if the animal became frightened and attempted to break away. Pass

the free end of the rope through the hole in the manger or around the

hitching rack. Form a bight or loop with the free end of the rope and

hold the loop along the standing part. With the free end form another

loop and serve around both the first loop and the standing part.

Complete the tie by inserting the second loop through the first loop

and secure by inserting the free end of the rope through the second

loop as shown. This is easily untied by first withdrawing the free end

from the loop and then pulling on same until knot is untied.

[Illustration: _Fig. 82; Fig. 83; Fig. 84_]

Fig. 82. The Harness hitch is employed for forming a loop on a rope

in such a way that strain may be applied to both ends and to the loop

without slipping. Start to tie an Over-hand knot as shown. Reach

through between the two twisted parts and draw the opposite side of the

loop through, following the arrow. The completed harness hitch appears

as shown.

Fig. 83. The Strap hitch or Line knot is used to join the free ends of

two leather driving lines on a team. It may be employed as an emergency

tie for a broken line or strap but is not to be recommended as a

permanent repair.

Fig. 84. The Clevis hitch is used for forming a loop on the end of a

rope which is both secure under strain and easily untied.
