Propeller blade patent model
In collection
From the Smithsonian Collection
George W. Swartz received a patent for a propeller-blade design in 1857. This model, submitted to the Patent Office with his application, demonstrates his proposal to use three of his blades together to form a complete propeller. Although his specification describes in detail the propeller’s geometry, it does not give any clue why Swartz felt these blades were an improvement over other designs then known. |
