Patent US-1895-582718
Substance: developments in glider frame, including springs which allow for changes in the wing to compensate for air pressure.
Chanute credits Louis-Pierre Mouillard with recognizing the need for "fore-and-aft movement of the wings in order to preserve the equilibrium."
The patent cites an earlier patent of Otto Lilienthal (not by number but Patent US-1895-544816 is a good candidate); Lilienthal Museum says: "The present invention is an improvement upon the flying-machine recently patented to Otto Lilienthal ...";
Chanute adds seat for operator and spring mechanism, which shifts the wings forward or backward depending on wind-pressure (air resistance); the higher the wind, the further back it will push the wings on springs; "In each case the shifting of the wings compensates for the change in the center of the wind-pressure due to the change in the velocity and operates to keep said center of pressure coincident with the center of gravity, thereby automatically preserving the equilibrium."
