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, 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 that class of mechanism where the pressure of carbonic
acid gas is employed to simultaneously supply and aerate beer and like liquids.
The invention consists of a combined mechanism by which the liquid is aerated
and the pressure of the released gas used to supply the liquid simultaneously; the
whole suitably arranged for attachment and use on a shop counter.
The method of carrying the invention into effect is illustrated in the accompany-
ing drawings as follows:-
Figure 1 is a part vertical section of the device,
Figure 2 is a plan of the device, and
Figure 3 is a detail in elevation of a portion of the mechanism.
The vessel a (which can be constructed of any suitable size or material) is formed
with a ground surface at its upper edge, so that the lid 6 with the groove d may
form a joint when placed thereon. This lid carries the drawing off or tapping
arrangement for the liquid and has formed in it, bolt openings 61, through which
bolts fastened to a ring on the vessel pass. A rubber ring e to make the joint is
compressed by the screwing down of the bolts in the slots b¹.
Upon the lid b and continuous with the tape is screwed an ascension pipe f
which reaches nearly to the bottom of the vessel a. The tape is fitted with a
hollow plug g of the usual type, and this plug has a carefully made packing cap
as shown; while the end of the plug g has a flat cut upon it so that the handle h
may be fixed. This handle h has a cam prolongation i opposite to and formed
integral with it; the surface k of this cam acting upon a spindle head u to be
hereinafter described. A nose piece is formed upon the cam extension i, so that
the motion of the handle h and the operation of the cam may be limited to such
an extent that when the tape is fully open the carbonic acid gas valve hereinafter
described is also fully open.
A carbonic acid holder m of the usual type has fixed to it a plug n with oppo-
sitely placed screwed ends. One end is screwed into the holder m and makes a
joint thereon, while the other end is screwed into the cover b also making a joint.
The axis of the carbonic acid holder m lies exactly under the cam extension i
and formed integral with the cover b is a shells containing a spring which acts
upon a spindle t. This spindle t carries at its upper end the cap u hereinbefore
referred to, and the spindle and cap are also co-incident with the axis of the
holder m.
The valve placed in the carbonic acid container consists of a lift valve q attached
to a spindler and moving against the resistance of a spring p. The spring p
is retained in position by a shell o screwed into the plug n and this shell o also pro-
vides the seat for the valve. The valve q is preferably arranged with a rubber

page_text: seating let into the groove as clearly shown in section, Figure 1, and when this
valve is opened by the depression of its spindle r, the gas escapes in the direction
shown by the arrows, up round a spindle i placed between the two spindles t and r
and through an opening or perforation into the top of the vessel a...

The spindle w is a loose spindle and it is placed in on the top of the spindle r
when the container m is screwed into position. It is evident that the gas pressure
within the container will keep the valve q tight when the said container is being
removed or attached, and the object of the removal of the short loose spindle w is
to prevent tampering with the container valve when not attached to the cover b.
The manner of working of the combined device hereinbefore described is as
follows: After the vessel a has been filled with beer or other liquid the lid 6 to
which the carbonic acid holder m and ascension pipe f have been previously
attached, is placed in position and screwed down by the bolts in the slots 6¹. The
handle h is in a horizontal position and when it is desired to obtain a supply of
fluid, the said handle is pulled over into a vertical position. The cam i acting on the
cap u, spindle t, spindle w, and spindler, depresses the valve q simultaneously with
the port in the plug g coming opposite the port in the tape. The pressure of the
released carbonic acid gas acts upon the surface of the liquid and forces it up the
ascension pipe f out at the tap nozzle. Simultaneously with the pressure causing
the discharge of the liquid, aeration also takes place, and it is evident that by a
slight modification of the herein before described device the aeration of the dis-
charged liquid may be varied.
As the nose piece 7 limits the opening of the carbonic acid gas valve; excessive
gas pressure can scarcely take place within the vessel a, but as a provision' against.
accidents a safety valve y may be attached to the cover b:

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. In an apparatus for supplying and aerating beer and like liquids, the provision
in' combination of; an outer vessel containing a carbonic acid holder with a lift
valve and an ascension pipe leading to the supply tap, a cam extension on the tap
lever arranged to depress a spindle operating the carbonic gas valve simulta
neously with the opening of the tap plug to the ascension pipe, all substantially
as and for the purpose herein before described.
2. The improvements in and relating to devices for supplying and aerating beer
simultaneously, substantially as and for the purpose hereinbefore described with
reference to the accompanying drawings."
