This invention relates to new and useful im

by compressed air.
More particularly, the invention proposes the
salvage of submarines or other ships which are
accidentally damaged or sunk, or 'which cannot

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
