As yet, I've no clue to have the keel be of any certain format.
Was it a simple beam? Was it a trussed complex?

As yet, I've no clue that there was any folding up for transport. I am yet guessing three large subassemblies: two large wing parts and a trussed keel part.
Loose the LE cable from the bowspriting keel truss; I am guessing the LE cables give compression to snug the upper large two parts of the wing complex beam.
I guess: no separate spreader; rather the spreader is simply the lower longeron of large complex beam that makes the span for the wing shape.

I am guessing the diagonal staying wires of the upper deck are fixed firmly; my guess is that the upper deck complex is a stay-assembled affair of two big parts: Left complex and Right complex.

And at the center of the upper front longeron at the upper deck there seems to be a joiner or compression-receiving coupler that receives the left and the right halves of the complex beam's front longeron.

Unhook the LE cables, split the complex span beam near that joiner or coupler into two large stay-shaped parts...and presto: no need to fold anything; and maybe even fit left complex beam into the cavity of the right part for some nesting savings of space. Then that leaves just the keel to place parallel or inside the nest.

Notice the beaking staying strut from nose to the center of what I am calling a coupler or joiner at the upper deck LE center. The staying strut would fix angles of the complex big beam relative to the keel.

As the sail material seems only to be held in place by the cable tension once the tension is off the two wing structures might pull outwards from their sockets and then can be laid on the fuselage structure for transport /storage.

Of the reported 200 flights I would think few would have been manned at the height indicated as the structure and construction looks precarious. The launch system ( i.e. five men on main plus one on control line ) is again a precarious arrangement in what would have been a considerable wind speed to get it to fly with 186lbs on board.

I doubt the device had much of a future other than a curiosity, as by 1926 light aviation was beginning to get popular outdating this mode of flight. Of course there are always those that yearn for more personal wings hence the reason for web sites like this.

1902
Image
Mrs. Leila Marie Cody became the first woman to fly with her ascent in the 'Man-lifting War Kite' in 1902. The British Army was interested in the single-passenger-carrying kite's reconnaissance potential, for it could be flown in winds too strong for balloons. Her husband Samuel Franklin Cody, a former cowboy and gold prospector, left the United States to Britain in 1889 to set up a Wild West show.

It is not clear why Cody became fascinated by kite flying. Cody liked to recount a tale that he first became inspired by a Chinese cook; who, apparently, taught him to fly kites, whilst travelling along the old cattle trail. However, it is more likely that Cody's interest in kites was kindled by his friendship with Auguste Gaudron, a balloonist Cody met while performing at Alexandra Palace. Cody showed an early interest in the creation of kites capable of flying to high altitudes and of carrying a man. Leon also became interested, and the two of them competed to make the largest kites capable of flying at ever-increasing heights. Vivian too became involved after a great deal of experimentation.
Financed by his shows, Cody significantly developed Lawrence Hargrave's double-cell box kite to increase its lifting power, especially by adding wings on either side. He also developed a sophisticated system of flying multiple kites up a single line, which was capable of ascending to many thousands of feet or of carrying several men in a gondola. He patented his design in 1901 and it became known as the Cody kite.
Balloons were then in use for meteorological and military observation, but could only be operated in light winds. Cody realised that kites, which can only be operated in stronger winds, would allow these activities to be carried out in a wider range of weather conditions. His kites were soon adopted for meteorology, and he was made a Fellow of the Royal Meteorological Society.[8]
In December 1901 he offered his design to the War Office as an observation "War Kite" for use in the Second Boer War, and made several demonstration flights of up to 2,000 ft in various places around London. A large exhibition of the Cody kites took place at Alexandra Palace in 1903. Later he succeeded in crossing the English Channel in a Berthon boat towed by one of his kites. His exploits came to the attention of the Admiralty, who hired him to look into the military possibilities of using kites for observation posts. He demonstrated them later that year, and again in 1908 when he flew off the deck of battleship HMS Revenge on September 2. The Admiralty eventually purchased four of his War Kites.[8]
In 1905, using a radically different design looking more like a tailless biplane, he devised and flew a manned "glider-kite". The machine was launched on a tether like a kite and the tether was then released to allow gliding flight. The design showed little similarity to his earlier kites but had more the appearance of a tailless biplane. It was notable in being the first aircraft to use ailerons (in fact they were elevons) effectively to control roll.[8]
Cody eventually managed to interest the British Army in his kites. In 1906 he was appointed Chief Instructor of Kiting for the Balloon School in Aldershot and soon after joined the new Army Balloon Factory down the road at Farnborough, along with his purported son Vivian. The Factory would eventually become the Royal Aircraft Establishment and Vivian Cody would go on to a long and successful career as a technical specialist.[8] In 1908 the War Office officially adopted Cody's kites for the Balloon Companies he had been training. This group would in due course evolve into the Air Battalion of the Royal Engineers, No. 1 Company of which later became No. 1 Squadron, Royal Flying Corps and eventually No. 1 Squadron Royal Air Force.
Finally, in 1907 he created an unmanned "power-kite". Somewhat similar to his standard kite but with bigger wings and a tailplane with twin fins in place of the rear cell, this was fitted with a 15 hp Buchet engine. It was not allowed to fly free; Cody strung a long aerial wire down the length of the Farnborough Balloon Shed and flew it indoors.[8]

Rick,

Cody had taken his kiting system to an advanced stage of development before powered aircraft were available. The Argabrite kite was not past the basic stage of development to a practical man lifting system. Aeroplanes had superseded the need for aerial observation capabilities of a static kiting system.

By 1905 Cody had developed one of his kites so that it could be released into free flight and flown to the ground as a glider. This design has been the inspiration for some hang glider and human powered aircraft ideas.

Rick,

I tried posting other photos but they exceeded the site allowance of 4MiB.

Not sure how to convert but will try........

jpeg:- Cody's glider shown upside down. It does show a close coupled tailplane which is at odds with the statement in Ricks posting. The diamond ailerons beneath the wings are therefore not elevons.
