More particularly, the invention proposes the salvage of submarines or other ships which are accidentally damaged or sunk, or 'which cannot come to the surface for other reasons and also 2 ship. An airline I3 is mounted on or beneath the deck of the ship and also extends from the bow to the stern. . This airline I3 is associated with means for controlling its air operable from the interior and from the exterior of the ship. More specifically, the airline I3 connectswith‘ air pipes Iä. pro to prevent sinking of Vessels. vided with normally capped unions I4’ exterior of 'I‘he invention proposes to characterize the sal the ship for connecting with an air hose from a vage device by an air pipe line extending from the 10 rescue ship. The air pipe line I3 is'also pro bow to th'e stern of the ship and controlled with vided with three Way valves l5having operating valves operable from the interior or exterior of the ship. With this arrangement it is possible handles I6 and I‘l, one of which is interior of the ship and the other exterioro'f the ship, see par for a rescue ship to connect up an air line with ticularly Fig. 3. The three way valves I5 connect said air line pipe. The invention also contem 15 the airline I3 with branch lines IB certain of plates the use of a plurality of branches from which connect with `air pumps or similar mecha, said air pipe line'to compartments built into said nism I9 within the ship. ‘ ' ì submarine or ship.

For further comprehension of the invention, and oi the objects and advantages thereof, ref erence will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth. In the accompanying drawings forming a mate rial part of this disclosure: Fig. 1 is a side elevational view of a ship 40 equipped with salvage means constructed in ac cordance with this invention. Each of the compartments I2 is provided with a one way valve 2| in its bottom by which the compartments may be drained under pressure. These one way valves 2| are normally urged into closed positions by springs 22. They open auto matically when pressure is built up within the compartment. The outer walls 23 of the compartments I2 are associated with means for sealing breaks in th‘ese walls provided the breaks are not too large. The Walls 23 are of hollow construction and contain closely spaced screens 24. The space between Fig. 2 is a plan view of Fig. 1. the screens is indicated by reference numeral 25. Fig. 3 is a fragmentary enlarged sectional view This space 25 connects up with a supply of tar taken on the line 3_3 of Fig. l. 45 composition 26 or some other chemical which Fig. 4 is a fragmentary enlarged sectional view may be softened to flow by heat.

Steam radiating pipes taken on the line 5_5 of Fig. 3. 21 extend through the tar or other material 25. The salvage means for ships by compressed air, 50 These steam radiating pipes have their ends pro in accordance with this invention, is used in com vided with normally capped unions 28 by which bination with a submarine or ship ID having a they may be connected up with a steam supply plurality of partitions II dividing off a plurality from a rescue ship. of separated compartments I2.

In combination with a submarine or ship having a plurality of compartments from bow to stern, an air pipe line extending from said bow to said stern, means for controlling air in said flooded and the ship sinks to the bottom, persons within the ship may attempt to empty the com partments I2 by connecting up the pumps I9 for pumping air into the compartments so as to force out the water through the one way valves 2l. A ship coming to the rescue may assist this operation, or may carry out the operation. However, it is ñrst necessary that the caps or plugs be removed from the unions I4’.
