Description

“Looking down access tube of Argosy & Argonaut III.” A man is at the end in shadow. This is Simon Lake’s salvage tube. A salvage worker could simply enter the tube from the surface and walk down the tube to the submersible, close a hatch, pressurize the compartment, and open the bottom hatch which gave him safe access to the sea for salvage or harvesting operations. This device was referred to as “the stairway to the sea.” With it Simon Lake had made a profit primarily salvaging sunken coal barges.
