page_text: I, WILHELM KRÜGER of 20 Michaelkirchestrasse, Berlin in the Empire of Germany,
Manufacturer, do hereby declare the nature of this invention to be as follows :-
This invention has for its object a syphon bottle for beer, designed to produce a
complete utilization of the carbonic acid, whilst maintaining the beer for private
use under constant pressure. The essential characteristic of this improved syphon
bottle consists in the beer rising to the draw off tap through a pipe which passes
through the carbonic acid reservoir, whilst a reducing valve regulates the admission
or access of the carbonic acid by means of a lever standing under the pressure of an
adjustable spring.
A carbonic acid container is suspended in a beer vessel and attached to the closing
piece of the latter. The closing piece, which also carries a reducing valve and a
draw-off tap, is tightly connected with the beer vessel by means of a wing nut
screwed on a pivotted bolt and adapted to engage lugs.
The carbonic acid is introduced into the container through an opening in the
closing piece capable of being closed by means of a screw, and passes from the
container through the bore of a screwed piece into the reducing valve, the pressure
of the carbonic acid forcing back one arin of a lever, which stands in front of the
said bore, whilst another arm of the said lever extends against a diaphragm and is
influenced by springs. If the pressure in the reducing valve rises too high, the
diaphragm is extended, and the lever under the pressure of one spring closes
the bore. If the excess pressure be removed, another adjustable spring returns the
lever, thus again opening the bore so that carbonic acid can again flow into the
reducing valve. From the chamber of this valve the gas passes through another
passage into the beer vessel and expels the liquid from the same through a pipe
which passes through the interior of the carbonic acid container and rises to a draw-
off tap.
Owing to the pipe passing through the carbonic acid container, a cooling of the
beer is obtained without the use of ice or the like.
In order to exclude any danger of an explosion, a safety valve is further placed
on the reducing valve, and is so adjusted that on a given pressure being exceeded,
it allows the carbonic acid to escape.
When filling the syphon or jug the air flows out through an air tap. A handle is
provided to facilitate the conveyance of the apparatus.

page_text: COMPLETE SPECIFICATION.
An Improved Syphon Bottle for Beer and the like.
I, WILHELM KRUGER of 20 Michaelkirchestrasse, Berlin in the Empire of Germany,
Manufacturer 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 has for its object a syphon bottle for beer, designed to produce a
complete utilization of the carbonic acid, whilst maintaining the beer for private
use under constant pressure. The essential characteristic of this improved syphon bottle
consists in the beer rising to the draw-off tap through a pipe which passes through
the carbonic acid reservoir, whilst a reducing valve regulates the admission or
access of the carbonic acid by means of a lever standing under the pressure of an
adjustable spring.
In the accompanying drawings this improved syphon bottle is shown in sectional
elevation.
A carbonic acid container c is suspended in a beer vessel a and attached to the
closing piece 6 of the latter. The closing piece, which also carries a reducing
valve d and a draw-off tap e, is tightly connected with the beer vessel by means of
a wing nut screwed on a pivotted bolt and adapted to engage lugs.
The carbonic acid is introduced into the container c through an opening f in the
closing piece 6 capable of being closed by means of a screw and passes from the
container through the bore of a screwed piece into the reducing valve d,
the pressure of the carbonic acid forcing back one arm of a lever h which stands in
front of the said bore g, whilst another arm of the said lever extends against a
diaphragm i and is influenced by springs and l. If the pressure in the reducing
valve rises too high, the diaphragm is extended and the lever h under the pressure
of the spring closes the bore g. If the excess pressure be removed, another
adjustable spring & returns the lever, thus again opening the bore so that carbonic
acid can again flow into the reducing valve d. From the chamber of this valve the
gas passes through another passage m into the beer vessel a and expels the liquid
from the same through a pipe n which passes through the interior of the carbonic
acid container and rises to a draw-off tap e.
Owing to the pipe n passing through the carbonic acid container, a cooling of the
beer is obtained without the use of ice or the like.
In order to exclude any danger of an explosion, a safety valve p is further placed
on the reducing valve d, and is so adjusted that on a given pressure being exceeded,
it allows the carbonic acid to escape.
When filling the syphon or jug the air flows out through an air tap q. A handler
is provided to facilitate the conveyance of the apparatus.
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 :
A syphon bottle for beer and the like in which the discharge pipe (n) is 80
arranged as to pass through the carbonic acid vessel (c), and the reducing valve (d)
for regulating the inflow of gas is operated by means of a lever (h) acting under
spring pressure; substantially as hereinbefore described and shown in the
accompanying drawings.
