Patent US-1913-1059036
Airship which stores the engine exhaust in an insulated chamber. Begins takeoff heavier than air but becomes lighter as the engine produces exhaust; but also designed to use the lift effect like an airplane.
After starting the engine the exhaust gases are directed into chamber 2 through pipes 18 and 19 by cutting off the exhaust to the atmosphere by aid of valve 21. The heated exhaust gases from the engine displace through the opened port 7 the cool air in the chamber 2, and fill it with a specifically lighter gas which, while confined in the chamber, causes the ship to rise from the ground and to such elevation as desired for continuing the flight. The exhaust is then directed to the atmosphere through pipe 20. Ascension is also assisted by the action of the propeller and aero-plane 14 by reason of the angular relation of the propeller shaft and aero-plane surface. The thrust of the propeller causes the forward end of the aero-plane to elevate, thereby enabling the plane to exert a lifting force. Should the ship enter warm air currents and expand the gas field 1 causing the ship to ascend during its course, this effect may be counteracted by partially opening port 7 and regulating the exhaust valve 21.
Over a long flight the consumption of fuel can decrease weight, for which release of lifting gas compensates.
Also includes design for screw propellers which doesn't seem to make it into the claims.
