The picture of a Cody kite down there is one of Cody's earliest experimental designs. Cody made quite a few, but I won't list all the variations and details here.
It's easy to see the origins of this kite's basic construction lay in the Hargrave double box kite. Cody was after even more lifting power and stability though. Also very influential was the old American Blue Hill Meteorological kite design of the time.
Some of the original kites are still in existence. I know of one Cody kite in particular, a smaller model with side-sails that lean outwards at the top rather than being absolutely parallel like a classic box. Here's a few notes on the materials.
However, in his bigger kites, the sails were usually silk. Also, more use was made of American hickory for the spars, since this material has greater strength than bamboo. Like the early Hargrave kites, the sails were tensioned up to be drum-tight.
If you're interested in building a Cody kite for yourself, it's possible to work direct from copies of the original plans. For example, the Drachen Foundation in Germany can supply copies of the original blueprints of Cody's Mark III kite. This kite was designed and constructed for the Ministry of War, England.
If you're not ambitious enough to tackle a real Cody, try contacting Nico van den Berg for a simpler modern version of the Cody box kite. Or just purchase a simple retail Cody and scale it up and substitute your own materials and construction ideas.
Why haven't I quoted contact details for the above sources? These things tend to go out of date over time, so I'll let you do the detective work! Easy to do on the Web these days anyway.
So what did Cody actually do with most of his kites? Fly them in the park to amuse his grand-children? Well, no. He was mainly interested in man-lifting and multiple kite systems. Cody was the inventor of a clever system of sending up a whole train of his kites. That's called kite-stacking these days. At least a couple of copies of Cody's multiple kite system have been constructed for doing rather impressive displays at kite festivals!
Here's a quick description of one of these man-lifting systems...
Highest up is a small pilot kite to steady and guide the line. Following this are a whole series of lifter kites which, you guessed it, provide most of the lifting force. In strong winds you don't need as many, so this aspect of the system can be altered according to the weather. Last of all, closest to the ground, is the carrier kite. Under the carrier kite is suspended a chair or basket for the passenger.
I don't know why the word 'passenger' is often used, since this person is actually in charge of controlling their ascent and descent via a system of lines and brakes. At least that was the case in the original system.
Now for some background on Cody himself, who was born in 1867 and died in 1913. That's him over there on the horse. His full name was Samuel Franklin Cody, and to this day he is highly regarded in England for being a real pioneer of aviation in that country.
In fact, Samuel Cody is now referred to by many as the 'Father of British Aviation'.
In September 1993, a small band of enthusiasts formed the Cody Museum Trust to keep alive the memory of Cody the Aviation pioneer. The Trust became the Cody Society at a later date. But we're getting off topic here, back to the kites!
Somewhere around 1898, when Cody was taking his Wild West show around England, he became interested in building kites. He competed with his step-son Leon to make and fly the largest kites possible. They also attempted to fly these kites as high as possible. Finally, in 1901, they patented the winged box kite design we now know as 'the Cody kite'. It's design drew on the Hargrave double box kite and also the American Blue Hill Meteorological kite.
In December of 1901, Cody offered this design to the War Office which at that time was involved in the Second Boer War. To prove its suitability for aerial spotting, he flew it at various locations around London, at heights up to 600 meters (2,000 feet).
A number of other accomplishments followed. He mounted a large exhibition of his kites at Alexandra Place in 1903. Later on, he even managed to cross the English Channel in a canoe, towed by one of his kites. The French kite surfers on the other side were surprised and shocked to see him coming over the horizon. Ok, I added that last bit... History can get a bit dull after a while, just trying to keep you awake. :-)
The British Navy sat up and took notice after this, and even paid him to look into using kites as observation platforms. A few demonstrations followed where he hoisted an observer up into the air under a large kite. In 1908, Cody himself flew off the deck of the battleship HMS Revenge, in another man-lifting demonstration.
Cody's achievements were not the end of his man-lifting kite system. Since then, enthusiastic people have re-created the system, and demonstrated it.
For example, Nick Morse built a replica Cody kite system for a BBC documentary in 1977. It was used successfully for man-lifting at the first two Scheveningen kite festivals in 1977 and 1978.
Another system was later built by Berry Kramers and others. A Dutch man-lifting team has flown it many times, in different locations around the world.

"Love the easy to understand step by step instructions, made from next to nothing materials and above all so much fun to fly... cheers Tim for sharing your well thought out pdf kite designs with the whole world.
Very satisfying making your own and watching them get air-born for the first time."
"omg i made a kite from this site and i fly it ....... booom i didnt expect this bc in the other sites instuction are trash
