Multiple separate motors; thin cylindrical balloon; wire system for moving weight to achieve balance. Rigid frame:

This arrangement permits the use of rigid chambers as gas-spaces without bringing the gas into contact with the atmospheric air in the chambers during filling. The filling of the gas bags or envelops takes place without interfering with the cylindrical form of the balloon framework, which is continuously maintained by means of the outer casing d' and is only continued up to such a degree tat the necessary free space is left to permit expansion of the gas when the balloon ascends to great altitudes and when heated.

Inventor location (imputed by HistPat): Stuttgart, Germany

Occupation: "general-lieutenant z.d. general à la suite of His Majesty the King of Würtemburg"
