I, GEORGE CECIL DYMOND M. Inst. M.E., of the Agency for Foreign Patent
Solicitors 6 Lord Street, Liverpool and 6 Bank Street, Manchester, both in the
County of Lancaster and 323 High Holborn, in the County of Middlesex, Patent
Agent, do hereby declare the nature of this invention to be as follows:-
The object of this invention is the production of a life preserver which in case
of accidents in the water, by reason of the small space it takes up, and its light
weight, may be constantly worn on the person in such cases where there is a
possibility of danger from water, for instance, on ship board or during an
inundation and if danger be threatened it may be made ready for use in a few
seconds.
The apparatus may be also employed for military purposes, as by the use of the
same rivers may be crossed without any necessity for bridges, pontoons, or other
military engineering appliances.
The preserver consists of upper and lower air bags made of india-rubber or
other suitable air-tight material, which by means of a small india-rubber pipe
communicate with one another, or with a belt, which latter also serves as an air
bag. Air admission pipes which are provided with a cock serve for the intro-
duction of the air or other suitable gases. The upper air bags with the belt and
the lower air bags of themselves constitute a separate complete apparatus; how-
ever the whole arrangement may be so made that all the air bags communicate
with one another and in this case only a single air admission pipe is required.
The whole apparatus may be sewn in the lining of the vest, or of the shirt, or
that of the trousers, or it may be simply hung on.
The mode of using the apparatus consists simply in blowing air, in case of danger,
into the air bags through the air admission pipes, whereby the person wearing the
same is prevented from sinking.

Improvements in Life Preservers for Floating or Sustaining Persons
in the Water.
A communication from abroad by ALOIS ZADÁK, of Budapest, in the Kingdom
of Hungary, Purveyor.
1, GEORGE CECIL DYMOND M. Inst. M.E. of the Agency for Foreign Patent
Solicitors, 6 Lord Street, Liverpool and 6, Bank Street, Manchester, both in the
County of Lancaster and 323 High Holborn in the County of Middlesex, Patent
Agent, 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 :---
The object of this invention is to provide a life preserver to be used in case of
accidents in the water and which, by reason of the small space it takes up and its

page_text: light weight, may be constantly worn on the person when on board ship, during an
inundation or under other such conditions, and it can be made ready for use in a
few seconds. It may also be employed for military purposes, as, by its use,
rivers may be crossed, so doing away with the necessity for bridges, pontoons and
the like.
The preserver (shown in Figures 1, 2 and 3 of the accompanying drawings)
consists of upper bags B B and lower bags C C made of india rubber or other
suitable air tight material, which, by means of small india rubber pipes a a, com-
municate with each other or with a belt A, which latter also serves as an air bag.
D and E are admission pipes provided with cocks which serve for the introduction
of the air or other suitable gases. The upper air bags B B with the belt A of
themselves form a complete apparatus (as shown in the drawings) but it may be so
arranged that all the bags communicate with each other, in this case only one
admission pipe will be required. The whole appliance may be sewn in the lining
of the vest, shirt or trousers, or attached in any other suitable manner.
The mode of using it consists in simply inflating the bags with air or other gases
by means of the pipes D and E and the person wearing it will be prevented from
sinking.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is :-
A life preserver for floating or sustaining persons in the water, consisting of bags
formed of india rubber or other suitable material which are conveniently attached
to the lining of a person's clothing for constant wear when on board ship or other
places where the wearer may be exposed to the risk of drowning, and which are
provided with pipes D and E by means of which they can be inflated with air or
other gases, substantially as described.
