John George Aulsebrook Kitchen was an aero inventor in Scotforth, County of Lancaster, England.

Biographies on him online say he was born in 1869, and that he filed 175 provisional (British) patents.

Regarding his aero work, Waterbird.org give this substantial narrative:

Kitchen collaborated with Storey in 1910 to build an annular-winged aeroplane at Middleton Sands, Heysham, powered by a 50hp Gnome like Waterbird . . .

In 1911, he patented a pair of wheel-shaped floats with rubber rims attached to a transverse leaf-sprung undercarriage. When alighting on water, the watertight disc wheels would be in the horizontal position, but by operating 2 cranked levers, a seaplane would be transformed into a landplane by moving the discs through 90 degrees into the vertical position.

He applied with Storey for UK Patent No. 3,249 on 7 February 1914 for a reversing rudder which was accepted on 4 February 1915; such that reversing motors or reversing gears could be dispensed with, and, in some cases, also an ordinary rudder. Most of the experimental work was carried out at the boatyards of Borwick & Sons. It comprised 2 rudders, port and starboard, each of which was a half-cylinder. The halves of the rudder could be partially rotated, either together or independently, by means of concentric shafts. The unidirectional propeller rotated within the rudders, thus containing the slipstream. So, boats could be brought to a sudden stop or have extreme manoeuvrability. . . .

On 27 March 1918, Kitchen applied for UK Patent No. 124,572, which was accepted on 27 March 1919, to cover an extension to aircraft of the protection of his patent for the reversing rudder. Rudders in pairs, in addition to ordinary rudder or rudders, would be arranged at the tail of an aircraft, so as to ‘facilitate landing in confined areas, and quick manoeuvring, and to give the bomb droppers and gunners of fast aircraft a relatively slower moving mark, and thereby increase the efficiency of hits’. This principle was adopted to provide reverse thrust on jet engines when landing.
