Improvements in and relating to Supplying and Aerating Beer
and like Liquids.
I, CARL HERMANN AUGUST HORMANN, of 64, Arnoldstrasse Altona-ottensen, in the
Kingdom of Prussia, German Empire, Metal Manufacturer, do hereby declare the
nature of this invention and in what manner the saine is to be performed, to be
particularly described and ascertained in and by the following statement:-
This invention relates to that class of mechanisın where the pressure of carbonic
acid
gas is employed to simultaneously supply and aerate beer and like liquids.
The invention consists of a combination of mechanism by which the liquid is
aerated and the pressure of the released gas used to supply the liquid
simultaneously, while the whole is suitably arranged for attachment and use upon a
shop counter.
The method of carrying the invention into effect is illustrated in the accompanying
sheet of drawings as follows,-
Figure 1 is a vertical section of the device.
Figure 2 is a plan.
A vessel containing the beer or liquid to be supplied has bolted to it by suitable
joints a cover m, and the said cover m has formed integral with it a pillar A, while to
this pillar A a carbonic acid gas holder B is attached by means of a double ended
screw coupling n. The valve casing o is fixed within the gas holder B to the inner
end of the plug n and carries within it a spring held lift valve p. Co-axial with the
spindle of the gas valve p is a second spindle q, spring held as shown in a suitable
manner and carried by the plug n.
A supply pipe c projects down into the liquid containing vessel and is co-axial
with one side of a tap D, both the tap and the pipe being attached by suitable joints
to the cover m by a ring band joints d d d. The tap has a spindle e screwed at g
into an extension formed on the tap body and this spindle e has at one end a cone
surface f which forms a valve opening or closing the port from the pipe c into the
supply piper. Upon the outer end i of the spindle e (which is suitably packed by
the gland h) is a lever or handle k and the centre of this spindle e is co-axial with the
centres of the spindle 9 and the spindle of the carbonic acid gas valve p. The end i
of the spindle e just bears upon the end 8 of the loose spindle q when the valve ƒ and
valve p are shut; so that the opening of the valve f by the rotation of its spindle
simultaneously opens the non-return valve p.
The operation of the hereinbefore described mechanism is a simple one and is as
follows, When it is desired to supply the beer or like liquid from the container / the
valve f is opened by rotating the lever k. The backward movement of the end i
presses against the loose spindle q and forcing along the spindle of the valve p opens
it. Carbonic acid passes along the inside of the sleeve o through a space round the
spindle q and down a port or passage a into the container where it presses upon the
surface of the beer or like liquid forcing it up through the pipe c out past the valve f
into the supply pipe r; thus simultaneously aerating and supplying the liquid.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the saine is to be performed, I declare that what I
claim is :-
1. In an apparatus for supplying and aerating beer and like liquids the provision
in combination of; a vessel containing the liquid having a pipe projecting therein
in communication with a tap on the cover; a coned spindle valve screwed into and
controlling the said tap, a carbonic acid gas holder with a lift valve co-axial with the
coned spindle an interposed loose spindle which transmits the pressure from and
simultaneously opens the carbonic acid gas valve when the valve tap is opened, all
substantially as and for the purposes herein before described.
2.-Improvements in and relating to devices for supplying and aerating beer simul-
taneously, substantially as and for the purposes hereinbefore described with reference
to the accompanying drawings.
