Patent US-1916-1210376
Control planes with dihedral; different from ailerons. Description is 6 pages (long). Series of wings and control planes longitudinally ; normally 3 -- a big wing and a forward elevator and tail). Control planes can be set to have high or low dihedral. Goal: greater longitudinal stability, simple efficient control of elevation, and low resistance of elevation control. each control planes has dihedral angle which can be different from the others. The fixed planes and the control planes are all supporting planes. Control planes "always have the same angle of incidence". For take-off, the most-forward pair of control planes are set to horizontal plane and the aft-most pair are raised to dihedral of 30 degrees, the normal dihedral angle being 15. When gliding horizontally, the control planes are brought to their normal angle, matching the wings. In descent, the front pair are angled maximally and the back ones are either horizontal or match the wings. (Useful service of these adjustments is not transparent; would changing dihedral affect altitude significantly?) Ailerons and warping arrangements are not illustrated "as their application is well understood."
