I WILLIAM HENRY LE FEVRE of 26 Budge Row in the City of London
Civil Engineer do hereby declare the nature of this invention to be as follows:-
I use compressed air, compressed gas, liquified acids notably liquified carbonic
cid, stored under great pressure in a chamber attached to the vessel to be
flated; the gas is liberated when required, by the simple turning of a lever,
hich allows the gas to escape into the vessel and immediate inflation takes place.

COMPLETE SPECIFICATION.
A Novel Application of Compressed Air, Compressed or Liquified
Gases, and Notably Liquifled Carbonic Acid Gas for the Instan-
taneous Inflation of Life Belts, Life Buoys, and similar Apparatus
for Life Saving Purposes, Applicable also to Air Tight Compart-
ments in Vessels and for Raising Sunken Ships.
I, WILLIAM HENRY LE FEVRE of 26 Budge Row Cannon Street in the City
of London, Civil Engineer do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
I use compressed air, compressed gas, liquified acids notably liquified carbonic
acid, stored under great pressure in a chamber attached to the vessel, to be inflated;
the gas is liberated when required by the simple turning of a lever which allows
the gas to escape into the vessel, and immediate inflation takes place.
It is applicable to life belts, life buoys, and all life-saving apparatus; also to air
tight compartments in vessels and for raising suuken ships.
To perform this, I make the apparatus of any suitable metal.
I have two chambers one for containing the compressed air or gas, and the other
for regulating the pressure of the air or gas before passing into the article to be
inflated.
I have a lever with a projecting piece, which lever when turned forces the
projecting portion against a pin depressing a rod with a spring, and opening a valve
in the chamber in which the air or gas is stored.
The gas is then free to pass into the chamber for regulating the pressure and
into a casing with a tube attached which screws into the article to be inflated.
The gas is regulated by a valve fixed in any convenient part of the article to be
inflated into which the said tube screws.

In order that my said invention may be more readily understood and carried into
effect, I will proceed with reference to the accompanying drawings :—vis.—
Fig. 1 is a view of an ordinary life belt.
Fig. 2 is an elevation of the apparatus.
Fig. 3 is a section of same.
A. Fig. 1 is a life belt, one end being partly in section to show position of the
valve.
B. Figs. 1 and 3 is the valve.
C. Figs. 2 and 3 is the chamber for storing the compressed air or gas.
D. Figs. 2 and 3 is the lever or handle, with a projecting piece J, which, when
turned depresses a pin N, thus forcing a rod E in connection with a spring G.
thereby opening the valve seat and allowing the air or gas to pass through and
inflate.
F. Fig. 3 is the valve seat.
G Fig. 3. is the spring which operates the valve.
H. Fig. 3. is a cross piece to form a bed or fulcrum for the spring G.
I. Figs. 2 and 3. is a horizontal chamber for regulating the pressure of the air or
gas before passing into the article to be inflated.
J. Fig. 3 is the projection on the lever or handle D.
K Figs. 2 and 3 is a casing with a bearing M for the lever or handle to work in.
L Figs. 2 and 3 is a pipe with a screw at the end by which the apparatus is
attached to the article to be inflated.
N. Fig. 3, is the pin which is depressed by the projecting piece J.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is :-
1. The application of compressed air compressed or liquified gases, and notably
liquified carbonic acid gas, for the instantaneous inflation of life belts, life buoys,
and similar apparatus for life-saving purposes, also for air tight compartments in
vessels and for raising sunken ships.
2. The whole combination substantially as hereinbefore described.
