Patent US-1917-1355355
The phrase "multiple control" or "dual control", here means two aviators having joint control. (Elsewhere it seems to have other meanings.)
From the text of the specification: "The present invention provides a dual control wherein the aviators sit side by side in the machine, wherein the single lever or 'stick' for operating the lateral stabilizing means and the ascensional plane is used, and wherein the movements of each of the levers are the same as those given the lever in a single control machine, having a lever control. . . [If] a pupil loses presence of mind, through fright, or the novelty of an evolution of the machine, as for example, [in] a steep dip, he usually stiffens in the seat and braces his feet against the foot lever. The yielding, or slip connection in the rod 48 enables the experienced the experienced aviator, or pilot, to operate his foot lever, despite the opposition due to the other aviator bracing himself against his foot lever. This is of great importance in banking at a very steep angle, or in righting the machine when it is tilted over by gusts. In case the aviator who loses his presence of mind, holds onto his lever, the position of the experienced aviator beside him, enables him to push the frightened aviator off of his lever, or to strike him."
