KITES AND AEROPLANES

The Ship Kite

The ship kite (Fig. 1) is an odd shape for a wind-toy but a good sailer

in any breeze. It is quite easy to make and requires but one mast, four

yard-arms, a keel, some thin, strong twine, and the necessary covering

materials. The mast is thirty-six inches long, the lowest spar

twenty-four inches long, the top one twelve, and the two middle ones

proportioned in length to the two side-strings tied at the ends of the

top and bottom sticks—that is, at A and B on both sides of Fig. 2.

The keel of the frame is made from a thin piece of hard-wood that will

spring and keep its shape, such as hickory, oak, or birch; and after

soaking it in boiling hot water for a few minutes lash it fast to the

bottom of the mast and draw up the ends with the strings C, C (Fig. 2),

and carry the ends up over two yard-arms so the pressure of the keel

will not draw the lower yard-arm out of shape. The sticks should be of

good clear and tough white or North Carolina pine, spruce, or

white-wood, three-eighths of an inch square for the mast and the same

size but tapered at the ends for the yard-arms. Use strong cotton or

linen twine for the connections between spars and mast and draw them

taut but not so tight that they would spring the sticks out of shape.

From the ends of each yard-arm strings D D D are stretched and tied to

the mast so as to make an opening at the bottom of each sail. In

kite-making it is found a much better plan to have a number of planes

against which the wind can act instead of one large one that is often

unwieldy and difficult to handle.

This frame should be covered with thin paper muslin, sewed all around

the edges over the string-ribs and to the frame-sticks with strong

cotton thread. Do not have too much muslin overlap the edges, and after

going around the edges twice with the needle and fine cotton thread it

would be well to cut away all the unnecessary material as it only adds

weight with no benefit to the kite. Do not use paste or glue to fasten

the fabric covering on a frame; it only adds weight and does not stick

well.

Arrange the yoke as shown in the illustration of the ship kite (Fig. 1),

and to balance it make two funnel-drags or wind-anchors from thin wire

or wood hoops, nine inches in diameter, the funnel proper being of paper

muslin twelve inches deep. Use hickory or green birch for the hoops and

lap the ends for three inches; then bind them together with strong linen

thread.

Make the funnel-shaped bag of paper muslin and drop the hoop into it,

taking care to get an equal space all around from point of cone to edge

of hoop. Then sew the bag fast to the hoop and cut away all surplus

material. The yoke is made of two strong, thin cross-wires or strings

and the drop-string is fastened where they cross, as may be seen in Fig.

1.

The Chinese-junk Kite

The Chinese-junk kite (Fig. 3), is made in a similar manner to the ship

kite, but there are two masts, as the kite is broader and larger;

consequently the frame should be braced so that it will not rack in a

strong breeze.

The masts are forty-two inches high, the lowest yard-arm thirty-six

inches long, and the top one thirty inches in length. The bottom of the

hull is made from a piece of green hickory or birch sprung into place

and lashed fast with linen line. There are three inches of space between

the hull and lower sail and from two to three inches of space between

the other sails.

[Illustration:

THE CHINESE-JUNK KITE

]

The masts and spars may be of any light, strong wood, the masts half an

inch square and the yard-arms three-eighths of an inch tapered towards

the ends. The spars and masts are bound securely with fine linen line as

shown in the junk kite-frame (Fig. 4). It would look well to cover the

sail-frames of all these boat kites with white or very light-colored

muslin and the hulls with dark-brown, green, or black goods so as to

lend contrast and make the kites when in the air appear more like real

boats.

Arrange the yoke to this kite as shown in the drawing (Fig. 3), and add

as many funnel-drags as may be found necessary to steady this kite.

Instead of placing these wind-anchors close to the foot of the kite it

is often better to drop a cord five or ten feet with the funnel on the

end of it. While the funnel weighs but very little it is acted on by the

wind and is better than a heavy tail. As the wind blows stronger the

funnel is forced back and holds the wind, thereby dragging on the foot

of the kite and automatically shifting it to different angles so that

the wind will pass down along the planes and out through the spaces

underneath.

The Schooner Kite

The schooner kite (Fig. 5) is an attractive one when sailing up in the

wind, and for a kite the shape is very close to a real schooner in

proportions. The frame is built on a deck-stick thirty-seven inches

long, and six inches below it is the keel-stick twenty inches long. The

main-mast or aft-stick is thirty-three inches long and the foremast is

thirty inches from tip to tip. The foremast is set in twelve inches from

the bow end of the deck-stick and the main-mast is ten inches from this.

The gaffs are each nine inches long and are caught to both mast and a

top-stick, which is in turn lashed fast to the upper part of each mast.

Strings are run from place to place on these sticks as shown at Fig. 6,

then the sails and hull are cut from muslin and sewed to the strings and

spars.

The yoke is composed of three strings as shown in the drawing (Fig. 5),

and from the muslin cut two pennants and float them from the top of the

masts.

When up in the air this schooner kite will have a very real appearance

as the breeze will bulge the sails and give it the effect of tacking on

the wind. If the schooner is inclined to pitch or roll too much attach

two wind-anchors, one at the foot of each mast, and pay them out about

five or six feet.

A Balloon Kite

From four sticks and a long hickory rib the balloon kite-frame (Fig. 7)

is made. The cross-sticks are three feet and three inches long and the

uprights are each four feet long. The uprights are set apart six inches

at the foot and eleven inches at the top, while the cross-sticks are

twelve inches apart at both sides of the frame. Where the sticks cross

they are to be lashed and bound with linen twine; then the hickory rib

is sprung into position and lashed fast at the ends of the cross-sticks

and upper ends of the vertical sticks. A thong is to be bound to each

end of the rib and drawn down to the foot of the frame so that the curve

over the top formed by the hickory rib is even and symmetrical.

Cover this frame with dark-gray or green paper muslin, then make the car

from a hoop fifteen inches in diameter and a muslin funnel twenty inches

deep. Suspend the car on four strings attached to the foot of the kite,

and having arranged the yoke from the places where the sticks cross, as

shown in Fig. 8, this interesting sky-scraper will be ready for an

ascension.

An Air-ship Kite

The air-ship kite (Fig. 9), if large and well made, will present a very

realistic appearance when well up in the air.

The frame is made from dry spruce or pine sticks half an inch square for

the long ones and a trifle smaller for the shorter ones. The frame as

shown in Fig. 10 is seven feet long from A to A, and at the middle the

balloon is twenty-eight inches—that is, from B to B. The middle upright

stick is four feet long and the end sticks C C that support the car are

forty-five inches long. The middle upright B B is first lashed to the

middle of the long stick A A. The ends of the curved sticks are then

brought together and lashed to ends A A, and at the same time the unions

are made with sticks C C. After that the sticks between B and C are set

in place and securely lashed fast. The long sticks D D, forming the top

and bottom of the car, are four feet and four inches long. One is lashed

to the lower ends of the three long drop-sticks and ten inches above

that the top one is made fast.

With thin spring or hard brass wire bind the forms of the two occupants

of the car and make them fast to sticks D D with string. Then cover the

entire balloon and car as well as the men with dark-colored paper

muslin. Make the yoke of linen thread so that the kite will balance

well.

THE SCHOONER, BALLOON, AND AN AIR-SHIP KITE

]

Bat-wing and Crown-top Kites

Of the many odd shapes in which kites can be made perhaps the bat-wing

and crown-top are the most unique.

The bat-wing (Fig. 11) is made up on a frame composed of half-inch

square sticks for the longest ones and three-eighths-inch square ones

for the cross-ribs. The two long sticks (Fig. 12, A A) are six feet and

six inches, slightly tapered at the ends and separated about eight

inches. The long uprights B B are four feet and three inches and are

separated fifteen inches.

These two sets of sticks are lashed fast where they cross and the

horizontal ones are bound at the outer ends with short sticks twelve

inches in length. Fifteen inches up from the bottom a cross-stick, C,

four feet long is lashed fast; then the shape is described with stout

cotton or linen cord. This frame is to be covered with muslin and sewed

at the edges, and when ready to fly it arrange the yoke as shown in the

illustration (Fig. 11).

The crown-top kite (Fig. 13) is three feet and six inches wide, three

feet high, and one foot across the bottom. These sizes are for a kite of

medium size; if a larger one is desired it can be made five feet and

three inches wide, four feet and three inches high, and eighteen inches

across the foot. The sticks are from a quarter to half an inch square

and bound together with strong, thin cord (Fig. 14). Muslin is the

proper covering for this frame, but if thin, strong paper is preferred

it can be used to good advantage.

Sandwich Islands Bird Kite

One afternoon in the village of Paihiihi, on Maui, one of the Sandwich

Islands, I saw, at a considerable distance from me, a curious object

floating in the air and at first mistook it for a large bird. It would

glide about in graceful curves or dart suddenly towards the ground only

to soar upward just as suddenly, or poise motionless save for a slight

flapping of its wings.

But my blissful ignorance was soon dispelled by the laughter of a friend

who assured me that I was gazing at one of the kites of the cannibals—a

name sportively applied to a number of natives of the Gilbert Islands

who immigrated to Maui some time since. They are a more barbarous people

than the Hawaiians but seem to be amiable, and I have never known them

to eat anything _worse_ than a shark.

Wishing to see this new variety of kite, I started immediately for the

scene of action, and was soon in the midst of a dozen or more men and

women about half of whom had kites, which were larger than I had

supposed, being from thirteen to fifteen feet wide and two to three feet

high. When I arrived several were floating high in the air almost

directly over the men who held the strings—sometimes, indeed, sailing

directly over them.

I watched for some time their graceful, birdlike motion and then tried

to buy one. They seemed loath to part with them, however, and it was

only after I had exhausted nearly all my persuasive powers and all the

small change in my pockets that I succeeded in obtaining one. My awkward

endeavors to carry it away with me were greeted with much laughter until

one of the cannibals showed me the proper way to handle it.

[Illustration:

]

The drawings which I have made of one of these kites will enable any

enterprising boy to make one. As no tail is used great care must be

taken to make it perfectly symmetrical. It is also desirable to have the

kite very light and yet as stiff as possible.

The proper construction of the frame is shown in Fig. 15. The total

width of this kite is thirteen feet and the height at the middle is

thirty-two inches. First cut the middle stick C C thirty-two inches long

and lay it on the floor of a barn where a few nails can be driven in

temporarily to hold the sticks while bending them into the proper

shapes. Cut sticks D D, E E, and F F, and place them on the floor either

side of the middle one. The long, straight stick A A is twelve feet in

length, of half-inch basswood or pine, and slightly tapered with a plane

at both ends. Lash this to each of the cross-sticks, then with a long

stick bend the bow around nails driven in the floor as indicated by the

dots under the bow-piece in Fig. 15.

This bow-piece is half an inch square and tapered with a plane at both

ends. It would be well to pour boiling water on this stick for a

distance of three feet at both ends, so as to make it easier to bend.

Leave it in this position for a few hours until the water dries out and

the wood is shaped, then lash the top ends of the cross-sticks to the

bow-piece.

While bending the bow the two lower sticks may be shaped at the same

time. They should be of hickory or birch and tapered at the outer ends.

These must be shaped over nails the same as the bow-piece, then when

they are dry they are to be lashed to all the cross-ribs and the ends of

the bow with fine linen line. The cross-sticks need not be more than

three-eighths of an inch square, but the middle and top sticks should be

half an inch thick for strength. Draw cross-strings from the top and

lower ends of sticks D D, as shown in Fig. 15, to act as braces; then

cover the frame with thin, strong paper or muslin, sewing it fast to the

ribs with linen thread. The construction of the yoke is clearly shown in

Fig. 16.

Box Kites

High up in the air, much too high for the boys on the ground to see the

mechanical details, several queer-looking but powerful kites, or “gigs,”

were tugging at their strings in a stiff breeze. When these flying-gigs

were hauled down a big crowd of boys gathered to see them at close

range, and here are the pictures of them as well as the plan-drawings

showing how they are made. Any bright boy can easily follow these plans

and produce equally good and powerful kites.

The construction of the box kite is shown in Fig. 17, where the oblong

measures thirty-six inches high and twenty-four inches wide. These

oblongs are held apart at the top and bottom by sticks A A which measure

twelve inches in length. At the middle of the framework the corner

sticks B B are braced with two cross-sticks C, which are notched at the

ends, so that the inside corners of the sticks B B will fit snugly and

can be securely held with a slim steel-wire nail. This frame is made of

light pine sticks about three-eighths or half an inch square.

Eight inches below the top of the frame tie a cord, and nine inches

below this tie another one to the front upright sticks as shown at D D.

Cover the front, sides, and back of the frame with strong, thin Manila

paper or light, closely woven muslin, having the top and bottom open,

also the space at the front between the strings D D. A yoke caught at

the top corner of the box, as shown in Fig. 18, will be sufficient in a

light breeze, but for a strong wind add another from the side-sticks

where the top or bottom cord D is tied; this will steady the flying-box

and prevent its pitching.

[Illustration:

Fig. 17

Fig. 18

Fig. 19

Fig. 20

]

The “paralleloplane” is another powerful kite which is easily

constructed according to the plan shown in Fig. 19. The front frame is

thirty-six inches high and twenty-four inches wide and braced with

cross-sticks H H. The rear frame is forty-four inches long and fifteen

inches wide and is held in place ten inches behind the large frame with

sticks I I. Strings are tied to the top and bottom cross-sticks of the

large frame, and eight inches apart, as shown at J J, to which one end

of the paper or muslin is made fast. Fig. 20 will show the three fields

covered with cloth or paper, and when the paralleloplane is in the air

the space between the front planes admits the wind to the rear plane

with the extending tail, which tips the kite to the proper angle.

If these kites need balancing in very strong breezes, a yoke at the

bottom of the kites from which a long string may be suspended will take

some paper cross-bars, as shown in Fig. 21, or the wind-anchors can be

used. One or two of them may be hung from the bottom on a long string or

one at each lower end of the paralleloplane.

A messenger that will travel and travel fast is shown in Fig. 22, and as

they are very easy to make a number of them should be prepared for use.

Two thin sticks twelve inches long form the top and bottom yards for a

strip of muslin or paper six inches wide. From the four ends some thin

wire such as florists use is connected with a cork about twelve inches

in the rear of the sail, where it is bound fast with a few wraps of the

wire. A pin is passed through the middle of the top yard to the sail and

is bent over forming a hook, and in the cork another one is arranged in

a similar manner. The messenger can be hung on the string, and if there

are no knots to intercept its progress it will quickly speed away to the

kite.

The Flying-wedge and Double-plane Kite

Flying-wedge or double-plane kites are made in several shapes and sizes

with the planes arranged at different angles and in broken surfaces.

The flying-wedge is an interesting gig to make and hold when up, for it

is a strong puller. Its construction is shown in Fig. 23, and like the

box kite the frame is made of half-inch pine sticks. The front frame is

forty inches high and twenty-four inches wide, and the rear one two

inches longer but the same width. The frames are attached at the top but

held apart at the bottom by the sticks E E, which are eighteen inches

long. Twelve inches below the top a cross-stick F is attached, and from

the side-sticks down to the centre of the bottom cross-stick the sticks

G G are made fast. Strings may be substituted for these sticks but they

will not brace the framework so well. Diagonally across the back frame

and at the bottom strings are made fast to brace the frame, while the

back ones also help to relieve the strain of the wind on the paper or

muslin drawn across the framework. Figure 24 will show the fields

covered with paper or muslin, which are arranged so the wind passing

through the triangular opening in front presses against the back plane

and out at the sides and bottom, while some of it is forced up in the

top behind the upper plane and helps in the lifting power. Small flags

on sticks at the top add to the appearance of this flying-wedge which is

an exceedingly unique sky-scraper.

The double-plane kite (Fig. 25) is another form of the wedge. The

general plan and sizes for the frame of this wedge tally with those just

given, but the slight changes in the arrangement of sticks can be seen

in Fig. 26.

The plane at the front is just half the height of the kite, and at the

back it would be well to use two cross-sticks from corner to corner as

braces rather than string as suggested for the flying-wedge. Use paper

muslin for the covering and stretch it taut; then sew it fast. Rig up

two small flags on sticks for the top corners and arrange the yoke as

shown in Fig. 25. If the wedge is inclined to wobble or dive hang two

wind-anchors on the corners, preferably the front, as the action will be

better than if hung at the back.

[Illustration:

Fig. 23

Fig. 24

Fig. 25

Fig. 26

]

The wind strikes the front plane and upper part of rear bevelled plane,

also the outer edges of the rear plane, and in this manner a double kite

is made that will be found a strong and steady puller.

Kite-reels

Kite-reels are always useful things to help haul in long lengths of

string, and particularly if the kite is a strong puller and in a stiff

breeze.

A reel for kites with a good pull is shown in Fig. 27, and a boy with a

hammer, a saw, and a few nails can quickly put it together from some

box-boards sawed in two-inch strips. The reel is made of two thin boards

half an inch in thickness, cut circular with a compass-saw, and the hub

is shaped from an old rolling-pin that perhaps has been discarded from

the kitchen. It is impossible to give exact sizes owing to the possible

difference in the lengths of rolling-pins, but the round sides should be

at least six inches in diameter and placed twelve inches apart. One end

of the pin, or the handle, should be sawed and cut square so a crank may

be cut and nailed to it as shown at A in Fig. 28. From wood

seven-eighths of an inch thick cut the crank B, and attach a handle to

the outer end of it. Bore a hole with a bit in the end that fits over

the axle, and with a compass-saw or small chisel cut the hole square so

that the axle will fit snugly into it. The flanges are to be made fast

to the ends of the rolling-pin hub with nails or screws, and this

revolving barrel is hung in the inverted V-shaped frame of the reel. To

hold this reel down when winding in a line make several hard-wood stakes

as shown at C. These are cut out with a saw; and to protect the head and

prevent it from splitting off, bore two small holes through the head as

indicated by the dotted lines and slip steel-wire nails through them.

Place burrs over the pointed ends, cut the ends off, and with a light

hammer rivet the nail-ends down on the burrs so as to bind the head

securely. This is much better than winding wire about the head, since

the nails act as pins and will prevent the head from splitting while the

stake is being driven into the ground. The overhanging end of the head

laps on the end cross-plates forming the platform of the reel, and two

or three at the end opposite that at which the string is being hauled in

will hold the reel securely to the ground.

Another form of reel is shown in the illustration of a chest-reel (Fig.

30). This is made from two flat, good barrel-hoops, some braces, and the

reel and shaft as described in Fig. 28 A and B.

Two good, broad barrel-hoops are selected and cut so that they will

measure eighteen inches on the segment or twelve inches across the line

A A in Fig. 29. Two out-riggers B B are cut from pine or white-wood ten

inches long, two inches wide, and three-quarters of an inch thick; these

are bevelled at the end towards the hoop, where they are made fast with

screws. The outer ends of these sticks are bound with the stick C, and

near the inner ends and close to the hoop a binder-piece D is fastened

with screws.

The reel should be made first and clamped in place when the frame is put

together. The lower hoop is made fast to the short upright pieces C C,

shown in Fig. 30, and braced to the main out-riggers B B with

bracket-strips. All the unions are made with screws or long copper

rivets securely fastened at the blunt end with burrs over which the

copper end is beaten and riveted.

[Illustration:

]

Near the hoop-ends holes are to be made with a bit through which stout

cotton line can be passed and made fast so as to tie the reel to a boy’s

body (Fig. 30). The hoop-end should be bound with linen line at either

side of the hole so as to prevent the hoop splitting and the

lashing-thongs tearing away. This is a very convenient form of portable

reel and is easily carried about without having to touch it. A

friction-brake can be made from a piece of sole-leather that will bear

against the edge of one large end of the reel so that when paying out

cord it may be regulated as the kite draws on it.

Leather or metal washers should be placed between the reel-ends and the

frame that the axle is hung in so as to prevent friction and the

consequent wearing of the wood.

Fig. 31 shows a simple, home-made box-reel that will wind up a thousand

feet of line in short order. It consists of a box, to which the cover is

hinged, and two sprocket-wheels from an old bicycle. One large one has a

handle for turning it, the other, a smaller wheel, is fastened firmly to

a spindle (Fig. 32) that runs through the box. The box is of pine or

white-wood fourteen inches long inside measure, eight inches wide, and

ten inches deep. The wood may be from one-half to seven-eighths of an

inch thick, and the points should be made with glue and nails or screws

to hold them securely and prevent the box from racking.

Find two old sprocket-wheels and a piece of bicycle chain and make the

wheels fast to iron axles that will pass through holes made in the sides

of the box. The ends of these axles should be threaded and provided with

a nut so as to hold the axles in place when run through the box.

The arrangement of these wheels and the chain is clearly shown in the

illustration of a box-reel (Fig. 31). The large wheel should be attached

to an axle and one of the pedal-cranks made fast to it. Instead of the

pedal a wooden handle will slip on the pedal axle where it can be

secured by the nut that held the pedal in place. The relative positions

of wheels, axles, and other parts of this reel can be seen at Fig. 33. A

represents the crank, handle, and large wheel; B the axle that passes

through the box; C the axle and flanges made fast to the small

sprocket-wheel; and D shows how the wooden roller-wheels are arranged

over the slot in the box so that the string can be drawn in without its

touching the edge of the slot. The edges should be flared at the under

side so that the cord will wind on a fat reel without touching the wood

as shown at E.

Two wooden flanges should be cut from thin wood and made fast to the

axle C to prevent the cord winding on the axle close to the box and

thereby clogging its action. Leather washers separate the flanges and

the boxes so as to reduce the possibility of friction.

The slot cut in the top of the box should be as long as the available

winding-space on the axle, and protecting it at both sides are rollers

cut from one-inch curtain-poles or broom-sticks. Steel-wire

finishing-nails are driven in the end of each one, taking care to get

the nail exactly in the middle.

Bend two L-pieces from stout sheet-iron, and having punched or drilled

holes in the right place through the upright ear, make these bearings

fast to the top of the box with screws as shown at D in Fig. 33. By

turning the box slightly from side to side when winding in the string,

the incoming line will travel from end to end of the slot so that the

coil on the shaft will be equally thick from flange to flange.

A leather trunk-handle may be made fast to one end of the box for

convenience in carrying.

This form of direct gearing with sprocket-wheels and chain makes it

impossible for the cord-shaft to slip as it will do in the grooved wheel

and string or leather-belt connections. It is simple and sure and quite

as easy to pay out from as to wind in with.
