Abstract

121,072. Wilson, W. A. April 25, 1918. Propelling.-In aeroplanes, hydro-aeroplanes, air-ships, &c. provided with paddle-fans at each side driven in synchronism with the main tractor or propeller, the paddle-fans are rotated by cranks and connecting-rods engaging a cam-race secured to the tractor, and a screw is provided in front of the tractor and adapted to force air rearwards against cups or the like carried by the fans. Air driven by the fans is directed under the main planes or against deflectors for increasing the lift. The fans, provided with scoop-like blades q and cups r, are driven from a cam-race d' secured to the tractor a, by means of rods g, k and cranks m. An archimedean screw a<2> forces air rearwards, which is directed by pipes w<1> into the cups r. The fans operate in chambers x leading to pipes x<1> fitted with valves x<2>, x<10>, by opening which the air may be directed under the main planes or against deflectors x<20> respectively. Louvers y' at the front of the chambers x also direct air to the pipes x<1>. A clutch may be fitted between the tractor and cam-race. The inner surface of the paddle-boxes may be lined with cork, rubber, &c. with a view to deadening the sound. Planes, construction of.-The under surface of the main planes also may be covered with cork, rubber, &c. for the purpose stated above. Parachutes.-A parachute device comprises a funnel z fitted with flaps z<2> and leading to a pipe z<1>, which is closed at the top or opens under the main planes. Aerostats.-In the case of an air-ship, air may be passed from the pipes x<1> into a bag or envelope during a descent.
