Zahm's summary:

This invention relates to flying machines and has for its object to provide such a machine with wing tips or ailerons that will be adjustable in such a manner as to exert a torque about the longitudinal axis or line of flight of the machine with or without, as may be desired, exerting a resulting torque about its vertical axis.
To these ends the invention consists in an aeroplane or flying machine provided with a number of lateral balancing planes or lateral rudders, adjustable to any desired angle with respect to each other, yet free to turn together when desired so as to receive an equal impact from the air during flight and to be in aerodynamical balance about the vertical axis of the machine, together with a device whereby they will exert either equal or unequal torques about said axis, as may be desired by the operator.
