Improvements in or Appertaining to Apparatus for Preparing or
Preserving Aërated Drinks.
I, GUSTAF OTTO RENNERFELT, of Stockholm, in the Kingdom of Sweden, Engineer,
do hereby declare the nature of this invention to be as follows:-
The object of this invention is an apparatus by means of which the public will be
onabled to prepare aërated drinks without professional aid or to preserve beer, and
refreshing drinks against the action of the air.
Referring to the drawings
:-
Figure 1 is a vertical section of the apparatus on the line A, B Figure 2.
Figure 2 is a plan of the same.
Figures 3 and 4 represent the same in combination with a cooler and stirring
apparatus.
Figure 3 is a section on line A B Figure 4.
Figure 5 is a section of the reservoir containing carbonic acid for the apparatus and
its valve.
Figure 6 shows how the carbonic acid reservoir and the discharge cock of the
apparatus are mounted on a common supporting plate, by means of which they are
fixed to the vessel, in which the drink is prepared or kept.
Figures 7 and 8 respectively show the discharge cock viewed in plan and in section.
In these A is the vessel containing the liquid intended to be treated by carbonic acid,
B is the reservoir for compressed carbonic acid or a solution of the same, 6 is a valve
or a cock for letting in the carbonic acid into the vessel A, C is the discharge cock
for the liquid. D (Figures 3 and 4) is a cooler, E a stirror for hastoning the absorption
of the carbonic acid. The valve or cock is provided with a handle h, which is closed
when the apparatus is at rest, and the end of which rests and presses upon the button
of the discharge cock C, so as to keep it closed, and in this way to prevent the liquid
from flowing out, even though there would be a considerable pressure in the vessel A.
When the handle is turned and the valve opened thereby the carbonic acid gas will
enter through a side opening o on the reservoir, into the vessel A, and at the same
time the valve or cock C, which is normally closed by a`spring, will permit the liquid
to be forced through the piper and out of the spout p.
The cock b of the carbonic acid reservoir B is, as shown in Figure 5, provided with
a conical screw valve, above the spindle nut of which is located a strong spring
which ensures the handle of the spindle, when the cock is to be closed, to be turned
into a determined position without fear of the valve being either damaged or not
shut tightly.
The discharge cock C of the apparatus has a valve which, as shown by Figure 8, is
normally closed by spring pressure. The carbonic acid reservoir and the discharge cock
are both, as shown by Figure 6, fixed on a common fixture by which means they may
easily, and at the same time, be applied upon the vessel A and also retain their relative
position on the same.
As shown by Figure 5, the valve handle of the carbonic acid reservoir is provided
at its free end with a small pivoted spindle, which has below a slot with an opening
at one side so that, when the said spindle occupies its normal position and the valve
handle is turned towards the discharge valve C, the spindle button of said valve C
will enter into the said slot. The spindle being then turned by means of a suitable
key, the entire apparatus will be locked.

Improvements in or Appertaining to Apparatus for Preparing or
Preserving Aërated Drinks.
I, GUSTAF OTTO RENNERFELT of Stockholm, in the Kingdom of Sweden, Engineer,
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 an apparatus by means of which the public will be
enabled to prepare aerated drinks without professional aid, or to preserve beer, and
refreshing drinks against the action of the air.
Referring to the drawings accompanying the provisional specification :-
Figure 1 is a vertical section of the apparatus on the line A B Figure 2.
Figure 2 is a plan of the same.
Figures 3 and 4 represent the same in combination with a cooler and stirring
apparatus.
Figure 3 is a section on line A B Figure 4.
Figure 5 is a section of the reservoir containing carbonic acid for the apparatus and
its valve.
Figure 6 shows how the carbonic acid reservoir and the discharge cock of the
apparatus are mounted on a common supporting plate, by means of which they are
fixed to the vessel, in which the drink is prepared or kept.
Figures 7 and $ respectively show the discharge cock viewed in plan and in section.
In these. A is the vessel containing the liquid intended to be treated by carbonic acid,
B is the reservoir for compressed carbonic acid or a solution of the same, bis a
valve or a cock for letting in the carbonic acid into the vessel A, C is the discharge
cock for the liquid. D (Figures 3 and 4) is a cooler, E a stirrer for hastening the
absorption of the carbonic acid. The valve or cock 6 is provided with a handle h,
which is closed when the apparatus is at rest, and the end of which rests and presses
upon the button of the discharge cock C, so as to keep it closed, and in this way to
prevent the liquid from flowing out, even though there would be a considerable
pressure in the vessel A. When the handle is turned and the valve opened thereby,
the carbonic acid gas will enter through a side opening o on the reservoir, into the
vessel A, and at the same time the valve or cock C, which is normally closed by
a spring, will permit the liquid to be forced through the pipe and out of the
spout p.
The cock.b of the carbonic acid reservoir B is, as shown in Figure 5, provided
with a conical-screw valve, above the spindle nut of which is located a strong
spring which ensures the handle of the spindle, when the cock is to be closed,
being turned into a determined position without fear of the valve being either damaged
or not shut tightly.
The discharge cock C of the apparatus has a valve which, as shown by Figure 8, is
normally closed by spring pressure. The carbonic acid reservoir and the discharge
cock are both, as shown by Figure 6, fixed on a common fixture by which means they
may easily, and at the same time, be applied upon the vessel A and also retain their
relative position on the same.
As shown by Figure 5, the valve handle of the carbonic acid reservoir is provided
at its free end with a small pivoted spindle, which has below a slot with an opening
at one side, so that when the said spindle occupies its normal position and the valve
handle is turned towards the discharge valve C, the spindle button of said valve C
will enter into the said slot. The spindle being then turned by means of a suitable
key, the entire apparatus will be locked.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed; I declare that what 1
claim is :-
1. An apparatus for preparing or preserving drinks containing carbonic acid

page_text: consisting of a vessel to contain the drink with a reservoir placed therein for com-
pressed carbonic acid, the discharge opening of which reservoir opens towards the
interior of the vessel and can be closed by means of a screw valve, the handle of
which is so arranged that, when the carbonic acid valve is closed, it is adapted
to lock the tapping valve of the vessel, substantially as described and shown.
2. In an apparatus such as described for preparing or preserving drinks containing
carbonic acid, the arrangement of the carbonic acid reservoir and the discharge valve
fixed upon a common base plate by which means both may easily at the same time
be applied upon the vessel for the drink and so maintain their relative positions
unaltered.
3. In a reservoir for liquid carbonic acid attached to an apparatus for serving or
preparing aërated drinks, a screw valve provided with a conical point, which valve
traverses a nut, which, when the valve is closed, can yield a little, owing to the
nut being supported by a spiral spring, substantially as described and shown.
4. In an apparatus for preparing or preserving aërated drinks having a vessel for
the drink, a reservoir for compressed carbonic acid disposed in that vessel and a dis-
charge valve opening outwards and governed by spring pressure, which valve, when
the valve of the carbonic acid reservoir is closed is also closed by the crank, by means
of which the valve of the carbonic acid reservoir is actuated, the arrangement that
the valve crank of the carbonic acid reservoir is provided with a spindle, which is so
inserted in the crank, that it may be turned by means of a suitable key and
which below has a sweep with an opening at one side into which opening the
head of the discharge valve can go in or out only when the spindle occupies a certain
position, whereby the discharge valve may be locked when desired, substantially as
described and shown.
