17,212. Thomas, J. July 24. Air-casings, non-structural.-Comprises improvements in the construction and arrangement of receptacles adapted to be inflated by compressed air, the supply of which is controlled from a central station, for the purpose of minimizing the risk of sinking in the event of accident to the hull of the ship. Tanks A filled with air under pressure are disposed at intervals in the centre of the vessel and communicate by means of the main I to branch pipes N1, N", N3 along each deck. Inflatable receptacles B3 are connected to the branch pipes N1, N2, N3 by pipes n fitted with valves. The receptacles B3 are constructed of durable material and have the inlet pipe n fixed internally as shown. The main I is fitted with pipes provided with valves r2 for the supply of compressed air from air-pumps. Flexible inflated bags B2 are enclosed in airtight metal cases and fitted between the inner and outer frames of the plating and decks of the vessel. When the receptacles B3 are collapsed, they are secured to the underside of the decks by chains. In the event of accident, should it be desired to put out the fires in the boilers water is supplied by a pipe p from a tank T on deck, to the furnaces u.
