Sliding ballast for stability (envisioned for a biplane)
[...] a safety ballasting device at about the center of gravity of said machine, which, first, can be manipulated easily and quickly, according to the spread or area of the plane or planes to be balanced, and atmospheric conditions; second, will positively prevent any pitching or rocking or careening while in flight, and, when describing a curve, will prevent the presentation of too great a surface of the planes to the opposing air currents, and avoid the possiblity of the machine "turning-turtle", and third, will, in the event of the engine or propellers refusing to work, or other accident happening that would affect the propulsion of the machine, cause it to drop or glide downward in the same manner as a parachute and settle to earth n a horizontal position, without the possibility of its upsetting or alighting with such force as to throw out and injure or kill its occupants.
