Motorized Diving Chamber to Seek Sea Bottom Treasure (Dec, 1931)
Motorized Diving Chamber to Seek Sea Bottom Treasure
WITH so much sunken treasure lying around loose and unclaimed on the bottom of the sea, inventors have been stimulated to devise diving contraptions to explore ocean depths on treasure hunting expeditions. The latest diving machine to make its appearance resembles a fantastic sea beast, so strangely is it constructed. Protected with armor plate and thick glass observation ports, the chamber shown in the accompanying photo can descend to a depth of about 350 feet and stay there for as long as seven hours. Communication with mother ship is maintained through telephone equipment. The chamber roams under power of its twin screws.
