PROVISIONAL SPECIFICATION.
Improvements in and relating to Apparatus for the Production of
Aerated Beverages.
I, THOMAS RESTALL, of 27 King Street, Cheapside, in the City of London,
Gentleman, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in the construction of that class of
apparatus known as seltzogenes, gasogenes and the like, in which water or other
liquids or beverages are aerated or more or less charged with carbonic acid gas herein-
after referred to as gas, and has for its object to provide means whereby more perfect
and, in some cases, more economical aeration of such liquids can be effected than by
the use of the apparatus hitherto employed.
In the apparatus as at present constructed, the gas before it comes in contact
with the liquid to be aerated, must pass through a certain depth of air by which it
becomes diluted and moreover it is presented in this diluted state to the quiescent
surface only of such liquid, hence it is absorbed very slowly especially by the lower
portions of the said liquids. Furthermore, in such apparatus a large proportion of the
liquid introduced for the purpose of aeration is also used as a solvent for the solid
ingredients employed for the production of the said gas and is consequently rendered
undrinkable or at least unpalateable and in the case of the employment of wine or
other liquids in which the cost is a consideration it is absolutely wasted.
According to my invention in lieu of bringing the gas in contact only with the
surface of the liquid to be aerated I cause the said gas to pass through a tube which
I convey to the bottom or nearly to the bottom of the vessel containing such liquid
and I preferably provide the lower portion of the said tube with small holes or
perforations so that the gas therefrom shall issue in finely divided streams by which
means the liquid is agitated and intimate contact of the gas therewith is ensured.
To prevent the waste of the liquid to be aerated, for instance wine, I provide that
portion of the apparatus used for containing the same with an inlet furnished with an
air tight cap or some other suitable closing contrivance through which the said liquid
can be introduced and to that portion of the apparatus used for the solution of the
solid gas producing ingredients I provide a similar but somewhat larger inlet which
may consist of an ordinary glass nozzle to which is fitted an air tight cap or I provide
an inlet so constructed that during the introduction of the said solid ingredients no
waste of gas shall take place.
This may be effected by permanently affixing to the said nozzle a short cap having a
disc attached thereto one half of which or rather less than half is cut away and upon
which is accurately fitted a short cylinder or receptacle having a similar disc and an
air tight cap so arranged that upon removing the said cap, and having closed the
openings of the discs, the solid ingredients may be placed in the said receptacle which
upon being closed by the cap may be so turned that the said solid ingredients will
fall into the vessel used for their solution, without loss of gas.
Doted this 2nd day of March 1897.

Aerated Beverages.
I, THOMAS RESTALL, of 27 King Street, Cheapside, in the City of London, Gentleman,
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 the construction of that class of apparatus
known as Seltzogenes, gasogenes and the like in which water and other liquids or
beverages are aerated or more or less charged with carbonic acid gas, hereinafter
referred to as gas and has for its object to provide means whereby more perfect and
in some cases more economical aeration of such liquids can be effected than by the
use of the apparatus hitherto employed.
In the apparatus as at present constructed the gas before it comes in contact with
the liquid to be aerated must pass through a certain deptli of air by which it becomes
diluted and moreover it is presented in this diluted state to the quiescent surface
only of such liquid hence it is absorbed very slowly especially by the lower portion of
the said liquid. Furthermore in such apparatus a large proportion of the liquid
introduced for the purpose of aeration is also used as a solvent of the solid ingredients
employed for the production of the said gas and is consequently rendered undrink-
able, and in the case of the employment of wine or other liquids in which cost is a
consideration, it is absolutely wasted.
In order that my invention may be fully understood I will describe the same by
reference to the accompanying drawings in which
Figure 1 represents a seltzogene, partly in section, provided with my improve-
ments.
Figure 2 shows a modification of the means I employ to prevent waste of gas during
the introduction of the gas producing materials and
Figure 3 represents a detached view of a cap hereinafter referred to.
According to my invention in lieu of bringing the gas in contact only with the
surface of of the liquid to be aerated I cause the said gas to pass through the tube a,
Figure which I convey to the bottom, or nearly to the bottom, of the vessel d
containing such liquid and I preferably provide the lower portion of the said tube
with perforations a 1 so that the gas shall issue in fine streams by which means the
liquid is agitated and intimate contact therewith is ensured. This gas tube I prefer
to be of larger diameter than and surround the ordinary discharge tube b, though if
desired two or more gas tubes may be employed. I secure this tube or these tubes to
the contracted part c of the gasogene by means of a perforated cork and cement cl
or by some other suitable means in order to form two distinct vessels d and d 1 having
no communication with each other except through the said gas tube or gas tubes and I
carry the tube or tubes to as great a height as possible in the upper vessel d 1 in
order to prevent the passage into the lower vessel d of the fine spray given off during
the evolution of gas.
In the ordinary gasogene it has been usual to employ a certain proportion of the
liquid to be aerated also as a solvent of the materials used for the production of the
gas and in the case of wine being so employed this portion has been hitherto wasted.
To prevent this waste and in order to enable wine to be introduced into the vessel d
and water into the vessel d 1 I provide the vessel d with a separate inlet e having a
screw thread fupon which is fitted the screw cap g having the washer h, for the
purpose of making an airtight joint. The vessel d 1 I also furnish with a similar but
somewhat larger inlet e 1.which may be closed by the cap g 1 and washer hl, shown

page_text: detached in Figure 3, but I preferably employ the arrangement shewn attached to the
gasogene in Figure 1.
This arrangement consists of the tube i, preferably of glass, attached to the cap j by
means of cement or in some other suitable manner.
The working of a gasogene constructed according to my invention, as illustrated in
Figure 1 is as follows:-
Having filled the vessel d with the liquid to be aerated I close the inlet e by means
of the cap g, I then introduce into the vessel d 1 through the inlet e 1 sufficient water
to dissolve the solid gas producing materials say for example tartaric acid and
bicarbonate of soda and having inserted the former through the same inlet I place
the necessary quantity of bicarbonate of soda into the glass tube i slightly pressing this
material into the said tube so that it shall not be released therefrom until the cap j
has been screwed in place. This having been done I slightly tap the said cap, upon
which the bicarbonate of soda will fall into the vessel d 1 and the resulting gas passing
down the tube a and thence through the perforations a 1 will aerate whatever liquid
may be contained in the vessel d.
If desired, the cap g 1 Figure 3 can be substituted for the tube i and cap j, in this
case in order to prevent waste of gas I form the gas producing materials, or one of
them into cartridges by enclosing the said materials or one of them in paper or the
like to retard solution until the cap can be screwed in place.
In lieu of the tube i and cap j I may employ the modification illustrated in Figure 2
This arrangement consists of the inlet e¹ having the casing k secured thereto by means
of cement or in some other suitable manner. The bottom of this casing is partly cut
away forming an opening k 1 and into the said casing I fit the cylinder / also having an
opening 1.
I affix to this inner cylinder a flange m and I so arrange the same that the
openings 1 and 11 may correspond and permit communication with the vessel d 1.
Beneath the flange m I place a washer n and above the said flange I adapt a capg 11
for the purpose of making an air tight joint between the said washer, the top of the
casing h, and upper surface of the inlet e 1. To the cylinder I also fit the cap o
and washer o¹ in order to close the same effectually. The working of this modifica-
tion is as follows:-
Having inserted the necessary amount of water and tartaric acid into the vessel d 1,
I close the opening k 1 by turning the cylinder I then place the bicarbonate of soda
in the said cylinder and screw on the cap o.
When this is done I turn the cylinder /
so that the openings 1 and 1 correspond and upon giving a slight shake to the
apparatus the contents of the said cylinder will fall in the vessel d 1.
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 I
claim is.
1. A gasogene or similar vessel having an inlet for the liquid to be aerated and a
separate inlet for the materials used in the production of the gas substantially as
hereinbefore described and illustrated in the drawings.
2. The combination with a gasogene or similar vessel having separate inlets such
as described of the gas tube a Fig. 1 as and for the purposes described.
3. The improved gasogene or similar vessel substantially as herein before described
and illustrated by reference to the accompanying drawings.
