The Anderson Ellipsoid or safe Float System For Carrying the Foreign Mails, Exports and Imports of Money

Washington DC: Gibson Brothers Printers and Bookbinders, 1897. Hardcover. Fair. Hardcover. 48pp; 24 folding plates. Contemporary brown leather over boards. Most of spine perished, boards damaged at corner with a dampstain to the front; hinges starting but still holding fast, internally clean. Includes plans, specifications, a general and specific official estimate, drawings, and laudatory letters. Plans and description of a float device that would save the cargo [maybe the passengers] of any sinking steamer with which the device was fitted to. Anderson's design was inspired by the 1895 sinking of the steamer The Elbe by collision.

From what we can find it seems this invention was never adapted, and if it was, it wasn't widely used.
