Improvements in Syphons for Beer and Similar Liquids.
I, ALFRED KOCHMANN, of 27 and 29, Gartenstrasse, Breslau, in the German
Empire, 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 relates to syphons for containing and allowing the drawing off
of beer and other similar liquids.
A syphon constructed according to this invention consists of a suitable receptacle
for containing the liquid, provided at its upper part with a chamber in which
compressed carbon dioxide is stored. The gaseous dioxide is allowed to escape from
its chamber in order to exert pressure upon the surface of the beer, after pass-
ing through a reducing valve.
The accompanying drawings to which I will hereinafter refer illustrate in what
manner my invention may be carried into effect.
Figure 1 represents the improved syphon in elevation.
Figure 2 shews it in vertical section.
Figure 3 illustrates the cap of it in plan.
c is the vessel or receptacle for containing the beer or other liquid. In its
upper part it contains the chamber or reservoir a for the reception of the compressed
carbon dioxide, the upper part of this chamber being closed by a cover which
also acts as the cover to the vessel c. The cover is held in place by winged nuts
and screws e and is provided with suitable packing d. Through the chamber a
is passed a tube m and through the tube m the beer delivery pipe k passes, as
shown, to the tap g.
Arranged upon the cover bare the closable inlet h through which the compressed
carbon dioxide may be introduced, and the reducing valve f both opening into the
interior of the chamber a. Communication is established between the reducing
valve f and the space between the pipes m and k by means of a small piece of india-
rubber tubing i, which, if the pressure becomes too high, either bursts or blows
off. o is a back pressure valve.
The carbon dioxide passes through the reducing valve and the tube i to the
space within the pipe m, whence it is conducted into the receptacle c and exerts
its pressure upon the upper surface of the beer or other liquid which can then be
withdrawn through the tap g when the latter is opened.
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 I
claim is:-
-
1. A syphon for beer or other similar liquids, constructed and arranged sub-
stantially as hereinbefore described and as illustrated by the accompanying
drawings.
2. A syphon for beer or other similar liquids, consisting of a receptacle for
the liquid, a chamber for compressed carbon dioxide, a reducing valve through

page_text: which the dioxide passes, a rubber or similar safety tube to lead the dioxide
from the reducing valve to a space whence it is conducted to the liquid receptacle,
and a back pressure valve, all constructed and arranged substantially as herein-
before described and as illustrated by the accompanying drawings.
