Improvements in Life Belts.
I, MARYAN HRYNIEWIECKI, of Wspulna 10, Warsaw, in the Empire of Russia,
of no occupation, 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:-
This invention relates to an improved life belt which in case of distress can be
instantaneously inflated with gas in order to keep the person provided therewith
above the water surface.
In consequence of its peculiar construction and principally on account of its
capability of being instantaneously inflated with gas, the improved life belt is
of great importance and utility to persons on sea or river. The life belt when
not inflated being equal in size to an ordinary hosiery body belt with regard to
comfort it can be used with great success by sailors members of rowing clubs
and the like.
In the annexed drawing Fig. 1 shows the life belt extended flat whilst Figures 2
34 and 5 show the different parts of the gas apparatus.
The life belt a Fig. 1, is made of a texture of silk and india rubber, waterproof
and air fight at all parts. On each end of the belt a Fig. 1 a strap is attached,
one of which 61 is provided with a steel buckle. The straps 6 6₁ are used for
fastening the life belt round the body whilst the straps c and d are put over the
shoulders and fastened in front to the buttons e e of the straps b b¹.
The life belt is so put on that the gas apparatus f with the gas cartridge m
Fig. 4 lies in front of the wearer and the cap s of the gas apparatus being on
the right hand side which position is comfortable to the wearer and the most suit-
able for operating the inflation.
The gas apparatus f Figs. 2 and 3 consists of a copper housing g of cylindrical
form arranged in a copper base h h Figs. 2 and 3 and which is connected with the
material of the life belt.
Into the housing a metal cartridge m Figs. 2, 3, 4 and 5 filled with com-
pressed gas is inserted so that the pointed part n of the gas cartridge m abuts
against the edged conical pin o. This pin is fastened in the end of the housing g
and has two spiral shaped channels so that there remain two openings p p. The
gas cartridge m Figs. 4 and 5 is provided on its front end with an hermetically
closing metal stopper q.
On turning the screw caps of the apparatus the pin o pushes the metal stopper q
back and the gas instantly fills the life belt entirely.
The gas cartridge m may be held in the housing by means of a rubber ring i
passed over said cartridge.
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
0 I claim is:
1. An improved life belt constructed of a texture of silk and india rubber

page_text: which is adapted to be put round the body and can be instantaneously filled with
gas in case of need.
2. An improved life belt as in Claim 1 provided with a gas apparatus f contain-
ing a cartridge m filled with compressed gas the one end of which is in connection
with the belt and has a pressure pin o arranged in such a manner as to leave
spiral shaped openings p p, which pin when the screw caps is operated pushes
away the cartridge stopper 9, and allows the entrance of the gas into the life
belt.
