Saving Valuables in a Shipwreck 



What would happen if a ship equipped with the floating safes 

 should founder in a heavy sea? Water would enter the shaft 

 which holds the safes and would wash them overboard, 

 where they would float until picked up by a passing ship. 

 In this way the money, jewelry and other valuables of the 

 passengers as well as the registered mail would be saved. 

 At the right is a cross-sectional view of the ship showing 

 the floating safes in position, one for each deck
