COMPLETE SPECIFICATION.
Improvements in or connected with the Charging of Vessels with
Highly Aerated Liquids.
I, HANS SCHANDERL, Brewer, of 21, Neue Königstrasse, Berlin, 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 the process of charging vessels, such as bottles, casks, jugs etc., with
highly carbonated liquids was attended with considerable waste of carbonic acid,
or it required the use of isobarometric draw-off apparatus, which is expensive as
regards first cost and attendance.
The present invention has for its object, to provide a method of drawing-off
highly carbonated liquids, such as aerated water, sparkling wine and certain
kinds of beer, without appreciable waste of carbonic acid, by means of the cheap
appliances which are generally known and do not require skilled attendants.
For this purpose I perform the said operation in a locality in which the air
pressure has been increased above that of the atmosphere, so that the carbonic
acid contained in the aerated liquid will find in the locality in which the liquid
is drawn off the counter pressure otherwise existing only in the isobarometric draw-
off apparatus, the liquids have no tendency to form froth and consequently no
opportunity for losing an appreciable quantity of carbonic acid, the transporting
receptacles, such as bottles and casks, being, of course, sealed up in the same
locality, after they have been filled.
The room intended to be used for drawing off the liquid, must be provided with
means for closing it hermetically against the atmosphere, and air is forced into
it by means of an air pump, until the required pressure has been produced, which
may be ascertained by means of pressure gauges mounted in the room itself and
outside of the same.
The aerated liquid for filling the said receptacles is supplied through a pipe
which passes hermetically through the wall of the locality containing the said
vessels. Communication between the charging locality and the exterior may be
established through intermediate chambers or air-sluices, which can be closed air-
tight against the charging room and against the exterior, and which are used in
a manner analogous to the well known canal-locks.
During the day the charging locality is illuminated through air-tight windows
set into the walls of the same, and at night it is lighted by means of electric
Electric signalling
lamps situated in the locality itself or outside the same.
apparatus or telegraphs are provided which enable the workmen enclosed in the
charging room to communicate with persons outside.
The necessary change of air in the charging space may be obtained in a manner
similar to that adopted in the case of caissoons used for subaqueous building
operations.
Having now particularly described and ascertained the nature of the said
0 invention and in what manner the same is to be performed I declare that what
I claim is:-
1
The method of charging vessels with highly aerated liquids, which consists

page_text: in performing the operation in a room in which the air pressure has been raised
above that of the atmosphere, substantially as and for the purpose described.
2. The combination of a draw-off appliance or apparatus for charging bottles
and other liquid receptacles, with a hermetically closed charging room and acces-
sories, substantially as described.
