Improvements in Apparatus for Aerating Liquids.
We, HERMANN HAUSER of 31 Stockerstrasse Zurich Switzerland and OSCAR
BUNZLI, of 22 Lowenstrasse Zurich, Switzerland, Merchants, do hereby declare
the nature of this invention to be as follows:-
This invention relates to improvements in apparatus for aerating liquids, and
our invention consists in the improved apparatus hereinafter described in which the
liquid to be aerated is forced down through a preferably tubular saturator, which
saturator is filled with suitable separating material in order that the carbonic acid-
which is forced into the lower end of the saturator and passes out at the top-shall
in its passage be brought in contact with a larger surface of the liquid than in
aerating apparatus of the hitherto usual construction, said liquid being thereby
more thoroughly aerated or saturated with carbonic acid.
In carrying our invention into practice we employ a suitable carbonic acid
cylinder containing carbonic acid at a comparatively high pressure and said
cylinder is provided with a suitable reducing valve so that the pressure of the
carbonic acid is reduced as required. The carbonic acid is forced through a.
suitable pipe which is connected to the lower end of a vertically disposed saturator,
which saturator is filled with coarse or sharp materials such as broken glass, flint
stones pieces of burnt clay, pumice stones or the like. At a suitable distance over
the saturator we provide a reservoir containing the liquid to be aerated, which
reservoir is connected with the top part of the saturator by means of two pipes,
one of which pipes extends to about the top of said reservoir and the other pipe,
which is preferably bent to form a coil, is connected to the bottom of said
reservoir. Both said pipes are provided with suitable stopcocks and the arrange-
ment is such that the liquid from the reservoir passes down through the coil and
the carbonic acid passes up from the saturator into the top part of the reservoir,
through the other pipe. The coil between the reservoir and saturator, is
contained in a suitable cooling vessel adapted to contain ice or cold water for the
purpose of cooling the liquid as it passes from the reservoir to the saturator and
the lower end of said coil where it enters the top of the saturator, is preferably
provided with a rose so that the liquid is delivered in sprays into the saturator.
The action of our improved saturator is as follows:-The carbonic acid enters
the lower end and passes up the saturator passing through the liquid within said
saturator, the liquid and carbonic acid being caused to thoroughly mix and mingle
by reason of the separating material contained within the saturator. The carbonic
acid next passes through the pipe hereinbefore referred to into the reservoir and
assists in forcing the liquid through the coil into the saturator. After the liquid
has been saturated as described, it flows from the lower end of the saturator into
a suitable receiver from which it is forced to any suitable bottling machine or
apparatus.
As an alternative, we may dispense with the saturator in which event we put
the separating material herein before referred to into the coil so that said coil
which is contained in a cooling vessel as hereinbefore described, acts as a means
for cooling the liquid and at the same time as a saturator. We prefer in this
alternative construction of our improved aerating apparatus, to provide the lower
end of the cooling vessel with the receiver from which the liquid is drawn for
bottling.

page_text: As a further alternative, we may dispense with the cooling reservoir and we
combine preferably two bottling machines of suitable construction with our
improved aerating apparatus, the frames of said bottling machines serving as the
frames and supports of the different parts of our improved aerating apparatus.
Said bottling machines being adapted to fill either ordinary bottles or syphons
or both.
We wish it to be understood that we do not confine ourselves to any particular
construction of the different parts constituting our invention and that all the parts
may be made of any material or materials which are found in practice to be best
suited to their purposes.
We, HERMANN HAUSER of 31 Stockerstrasse and OSCAR BUNZLI of 22 Lowen-
strasse both in Zurich, Switzerland, Merchants, 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 improvements in apparatus for aerating liquids, and
our invention consists in the improved apparatus hereinafter described in which
the liquid to be aerated is forced down through a preferably tubular saturator,
which saturator is filled with suitable separating material in order that the carbonic
acid which is forced into the lower end of the saturator and passes out at the top-
shall in its passage be brought in contact with a larger surface of the liquid than in
aerating apparatus of the hitherto usual construction, said liquid being thereby
more thoroughly aerated or saturated with carbonic acid.
Such being the nature and object of our said invention, the following is a
complete description of same, reference being had to the accompanying drawings,
in which
Fig. 1 is a longitudinal section of the apparatus,
Fig. 2 is a similar section of a modification of the apparatus and
Fig. 3 is a front elevation of another modification.
In carrying our invention into practice we employ a suitable carbonic acid
cylinder containing carbonic acid at a comparatively high pressure and said
cylinder is provided with a suitable reducing valve vso that the pressure of the
carbonic acid is reduced as required. The carbonic acid is forced through a
suitable pipe which is connected to the lower end of a vertically disposed
saturator c, which saturator is filled with coarse or sharp materials such as broken
glass, flint, stones pieces of burnt clay, pumice stones or the like. At a suitable
distance over the saturator we provide a reservoir r containing the liquid to be
aerated, which reservoir is connected with the top part of the saturator by means
of two pipes d and s, one of which pipes d, extends to about the top of said
reservoir and the other pipe s, which is preferably bent to form a coil c³, is
connected to the bottom of said reservoir. Both said pipes are provided with
suitable stopcocks d¹ and s¹ and the arrangement is such that the liquid from the
reservoir passes down through the coil and the carbonic acid passes up from the
saturator e into the top part of the reservoir r, through the other pipe d. The coil
between the reservoir and saturator, is contained in a suitable cooling vessel k

adapted to contain ice or cold water for the purpose of cooling the liquid as it
passes from the reservoir r to the saturator c and the lower end of said coil where
it enters the top of the saturator, is preferably provided with a rose b so that the
liquid is delivered in sprays into the saturator c.
The action of our improved saturator is as follows: The carbonic acid enters the
lower end and passes up the saturator c passing through the liquid within said
saturator, the liquid and carbonic acid being caused to thoroughly mix and mingle
by reason of the separating material contained within the saturator. The carbonic
acid next passes through the pipe d hereinbefore referred to into the reservoir r
and assists in forcing the liquid through the coil c* into the saturator c. After the
liquid has been saturated as described, it flows from the lower end of the saturator
into a suitable receiver from which it is forced by means of the pipe l¹ to any
suitable bottling machine or apparatus a.
As an alternative, we may dispense with the saturator in which event we put the
separating material herein before referred to into the coil c, Fig. 2, so that said coil
which is contained in a cooling vessel kas herein before described, acts as a means
for cooling the liquid and at the same time as a saturator. We prefer in this
alternative construction of our improved aerating apparatus, to provide the lower
end of the cooling vessel & with the receiver y from which the liquid is drawn for
bottling.
As a further alternative, we may dispense with the cooling reservoir k and we
combine preferably two bottling machines a, a, Fig. 3, of suitable construction
with our improved aerating apparatus, the frames of said bottling machines serving
as the frames and supports of the different parts of our improved aerating apparatus.
Said bottling machines being adapted to fill either ordinary bottles (see to the left)
or syphons (see to the right) or both.
We wish it to be understood that we do not confine ourselves to any particular
construction of the different parts constituting our invention and that all the parts
may be made of any material or materials which are found in practice to be best
suited to their purpose.
Having now particularly described and ascertained the nature and object of the
said invention and in what manner the same is to be employed, we declare that
what we claim is :
1. In apparatus for aerating liquids a tubular saturator filled with separating
material which presents to the liquid to be aerated a large surface for its contact
with the carbonic acid and which is indestructible by carbonic acid.
2. In apparatus for aerating liquids such as described in the first claim a tubular
saturator connected at one end to a carbonic acid reservoir and at the other end to
a reservoir containing liquid, in such a way, that the liquid may pass down
through a suitable pipe into the saturator and the carbonic acid may pass up
through a suitable pipe from the saturator into the reservoir containing liquid.
3. In apparatus for aerating liquids such as described in the first claim a tubular
saturator contained in a suitable cooling vessel.
4. In apparatus for aerating liquids such as described in the first claim a tubular
saturator bent to form a coil, for the purpose to place a long tube in a small
vessel.
5. In combination with the apparatus for aerating liquids such as described in
the first claim two bottling machines serving as the frames and supports of the
different parts of the apparatus, said machines being adapted to fill either ordinary
bottles or syphons or both; substantially as described and shown.
