1, JOHN CLAYTON MEWBURN of 169 Fleet Street in the City of London, Fellow of
the Institute of Patent Agents do hereby declare the nature of this invention to he as
follows:-
-
Hitherto artificial aërated or gaseous waters or beverages have been manufactured
with carbonic acid gas. The present invention consists in the employment of nitrogen
gas in the manufacture of aërated or gaseous waters or beverages whereby drinks are
obtained of a refreshing and agreeable nature and under the best hygienic conditions.
For the purpose of manufacturing these nitrogenated waters it is preferred to obtain
the nitrogen from the air of the atmosphere by placing phosphorus under a bell glass
over a vessel of water so that the phosphorus by absorbing the oxygen from the air
and becoming converted into phosphoric and phosphorous acids which are rapidly
dissolved in the water will leave the nitrogen free but mixed with carbonic acid and
aqueous vapor which are found in small quantities in the air. In order to obtain the
nitrogen in a pure state it is passed through a weak solution of caustic soda with which
any particles of phosphoric and phosphorous acids and all the carbonic acid carried or
contained in the nitrogen become combined.
The pure nitrogen gas is passed into a machine such as the "Mondollot" machine
for example by which it is injected at a suitable pressure, say of 12 atmospheres, into
the water or liquid to be aërated or rendered gaseous: it is conducted under this
pressure to ordinary syphons," or it is supplied to bottles; or it may be stored for
use in cylindrical or other reservoirs of metal properly tinned or galvanized.

JOHN CLAYTON MEWBURN, of 169 Fleet Street in the City of London, Fellow of
the Institute of Patent Agents 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 :-
Hitherto artificial aërated or gaseous waters or beverages have been manufactured
with carbonic acid gas. The present invention consists in the employment of nitrogen
gas in the manufacture of aerated or gaseous waters or beverages whereby drinks
are obtained of a refreshing and agreeable nature and under the best hygienic
conditions.
For the purpose of manufacturing these nitrogenated waters it is preferred to obtain
the nitrogen from the air of the atmosphere by placing phosphorus under a bell or
inverted vessel which floats on or over and dips into water in a vessel or reservoir and
by igniting the phosphorus. The phosphorus during its combustion absorbs the
oxygen of the air under the inverted vessel and becomes converted into phosphoric
and phosphorus acids which are rapidly dissolved in the water while the nitrogen is
left free but mixed with carbonic acid and aqueous vapor which are found in small
quantities in the air. The phosphorus under the hell or inverted vessel can be ignited
from the outside through a hole made for the purpose this hole being then immediately
closed by a suitable plug. In order to purify the nitrogen thus obtained it is passed
through a weak solution of caustic soda with which any particles of phosphoric and
phosphorus acids and all the carbonic acid carried or contained in the nitrogen become
combined.
The pure nitrogen gas is passed into a machine such as the Mondollot machine for
example by which it is injected at a suitable pressure-say of 12 atmospheres, into the
water or other liquid to be aerated or rendered gaseous; it is conducted under this
pressure to ordinary "Syphons," or it is supplied to bottles; or it may be stored for
use in cylindrical or other reservoirs of suitable material.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, as communicated to me, 1 declare
that what I claim is :-
1. The manufacture of aërated or gaseous waters or beverages by the admixture or
incorporation of nitrogen gas with water or other liquid substantially as described.
2. The process hereinbefore described of manufacturing nitrogenated waters or
beverages which consists in first obtaining nitrogen from the air of the atmosphere by
the combustion of phosphorus, in then purifying the nitrogen by means of caustic
soda and in then forcing or injecting the pure nitrogen into the water or liquid to be
aërated or rendered gaseous all substantially as set forth.
