Patent NZ-1909-26981

Airplane with multi-part wing assembly, mounted on frame constructed of parallel vertical triangles. Small wings are hinged and attached to springs at the rear of the wings, so that they are elevated when the airplane travels at high speed but fall when it slows down. These hinged wings (i.e. automatic elevators) are therefore supposed to ease descents and provide additional stability if forward motion is suddenly disrupted in flight.
