Design for spindle-shaped LTA airship with semi-rigid structure created by cables. Balloon assumes different shapes at different levels of inflation; illustrations show these different shapes, with different gas pressure for each listed in the text. Though it wasn't necessarily made explicit on the original documents of the French certificates of addition, the original of this brevet makes reference to a Spanish predecessor, likely Patent ES-1906-38692.
