Aeroplane
Patent for an aeroplane that is inexpensive and easily built, while preventing the aeroplane from going into a tailspin.
Aeroplane-Kite.
Patent for a new aeroplane-kite which can be "readily dismantled and folded for shipping and easily assembled and placed in position for flying without the use of numerous fastenings and detachable parts, thereby making for simplicity and practicability" (lines 12-17). Also includes wind tunnels and a fuselage frame which is so easily assembled that a child can do it.
Aeroplane-Tail.
Patent for improvements to the tail of aeroplanes. This invention is to be used to help control the flight of planes or heavy projectiles, and would not have effects on the equilibrium or be difficult to use.
