Patent US-1910-957744
"Biplane" (two parallel planes); fabric stretched over frame; preferably the two planes are correspondingly concavo-convexly curved or dished but, with their concave surfaces facing each other (in other words, the top plane is convex up, while the other is convex down) this arrangement is said to counterbalance air currents and maintain stability of the craft; planes are extended by flaps, whose ends can flutter or vibrate so that air may pass through more easily (resembling bird wings); if the vessel suddenly halts, the parachutic effect of the top aeroplane will slow descent
Inventor location (imputed by HistPat): Washington, DC, (FIPSloc=11001)
