Sellmer Quadruplane
Sellmer working on Quadruplane
According to the 1932 photo and its press release, this was to be some form of an autogyro with a "large clutch-operated disc" (the spiral "lift") arrangement. The caption explains: "Runways and landing fields will not be necessary if this creation of J P Sellmer works out. When the motor is started, the lift is started whirling to raise the ship straight up. When the right elevation is reached, the spiral folds up and the engine drives the plane as does any other. In large ships, two spirals are to be provided to eliminate torque, and in small ones, a propeller at the back of the plane will prevent spinning." How far this grand idea progressed is unknown.
