PROVISIONAL SPECIFICATION.
Improvements in Soda and other Mineral Waters and the Mode of
Preparing same.
AUGUSTINE WILLIAM ORR and FINGAL HARMAN ORR both of 57 Upper
Sackville Street Dublin, Manufacturers of Mineral Waters, do hereby declare the
nature of this invention to be as follows:-
The more thorough saturation of soda and other mineral waters with carbonic acid
gas by means of chemical changes in the body of the waters, said changes to be
caused by the addition of certain quantities of pure hydrochloric acid to the waters
containing bicarbonate of soda in solution, thereby producing chloride of sodium
and free carbonic acid gas; and the facilitation of the absorbtion of the carbonic
acid gas by previously extracting the atmospheric air contained in the water by
suction by means of air pumps, aspirators, or other means for producing a vacuum
in the upper part of vessel containing the water to be saturated.

COMPLETE SPECIFICATION.
Improvements in Soda and other Mineral Waters and the Mode of
Preparing same.
AUGUSTINE WILLIAM ORR and FINGAL HARMAN ORR both of 57 Upper
Sackville Street Dublin Manufacturers of Mineral Waters do hereby declare the
nature of this invention and in what mauner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
The nature of this invention is the more thorough saturation of soda and other
mineral waters with carbonic acid gas by means of chemical changes in the body of
the waters, said changes to be caused by the addition of certain quantities of hydro-
chloric acid to the waters containing bicarbonate of soda in solution thereby
producing chloride of sodium and free carbonic acid gas, and the facilitation of the
absorbtion of the carbonic acid gas by previously extracting the atmospheric air
contained in the water by suction by means of air pumps, aspirators, or other means
for producing a vacuum in the upper part of the vessel containing the water to be
saturated. The chemical changes may be obtained by use of other acids than
hydrochloric and other salts than bicarbonate of soda according to the mineral
water required to be produced. The way we perform this is-we have an airtight
vessel of copper or other suitable material of sufficient strength with an agitator
working in same and having an air pump or other means of obtaining vacuum
attached-we introduce into this a quantity of water in which, we have disolved
certain proportions of salts according to nature and strength of mineral water
required we then proceed to create a vacuum in the upper part of vessel
agitating the water at the same time-when we have obtained sufficient vacuum we
open a valve or cock leading to another vessel containing the acid necessary for the
chemical changes and admit drop by drop the desired quantity of acid the agitation
of the water being meantime continued. The water is then charged with carbonic
acid gas in the usual manner.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :—
.
+
The setting free a carbonic acid gas by means of chemical changes of substances
contained in and added to a body of water in a vessel in which a vacuum has been 5
created,
