PROVISIONAL SPECIFICATION.
Apparatus for the Conveyance and Drawing Off of Beer.
I, VALENTIN LAPP, of Nos. 3 and 4 Kaiser Wilhelm Strasse, Leipzig-Lindenau,
Saxony, Germany, do hereby declare the nature of this invention to be as
follows:-
My invention relates to apparatus for the conveyance and drawing off of beer
wherein the discharge of the beer is effected by the aid of a pressure chamber filled
with a gas, preferably carhonic acid, at comparatively low pressure, which chamber
communicates with the receptacle containing the beer.
This apparatus serves as a vessel for the conveyance of beer for domestic use;
it is preferably constructed as follows.
A cylindrical or other shaped vessel, adapted to contain the beer, has fixed on
its coned or tapering upper end a closed chamber of smaller diameter, for containing
gas under pressure, such as carbonic acid.
The beer chamber may have, for example, a capacity of about 5 quarts, and the
gas chamber a capacity of about 3 pints. In the beer chamber a pipe leads from
a drawing off cock at the upper part down to close to the bottom; the cock may
have its orifice closed by a cap for preventing dripping.
For catching drippings from the cock when drawing off, a shallow tray extending,
partly round the beer chamber may be fixed on the outer surface thereof underneath
the cock.
For filling the beer chamber an opening is provided on the coned or tapering
upper end, which is closed hermetically by a screw stopper, situated at the same
level with the gauge mark, so that it is only possible to fill the vessel with the
exact measure of beer.
The small space remaining in the chamber over the liquid is filled with carbonic
acid gas.
The chamber containing the latter is made of such a capacity relatively to the.
beer chamber that a charge of gas at comparatively low pressure (about 1 to
2 atmospheres) shall be sufficient to force the whole of the beer out of the chamber.
The gas chamber is fixed on the top of the beer chamber either by soldering,
screwing, or in any other airtight manner.
The gas is conveyed from the chamber into the beer chamber by means of a pipe
extending from the top of the gas chamber first upward with a bend and then
downward either through the gas chamber into the beer chamber, or down along.
the outer side of the gas chamber and then into the coned upper part of the beer
chamber. The upper bend of this pipe is provided either with a regulating cock
or with a reducing valve for regulating the pressure of the gas as it enters the beer
chamber. The bend, which is made removable from the apparatus, also has a
branch pipe closed by cock or screw cap, through which the chamber is charged
with gas in the first instance. The opening of the pipe within the heer chamber is
preferably provided with a check valve.
The gas chamber also has an opening closed by a screw plug, through which any
water that may accumulate therein, can be drained off.
The can is provided with a looped pivotted handle for carrying, and it has a
downward projecting rim at bottom to stand on.
The apparatus is preferably made of metal such as copper tinned inside and
coated with enamel for preventing any action on the beer. In making the apparatus

page_text: of metal, it can be readily cleansed by the introduction of steam; which is of
importance for insuring the good quality of the beer.
Instead of fixing the gas chamber on the top of the beer chamber as described
it can be fixed at the side thereof, in which case it may project into the beer
chamber, which may be either cylindrical or barrel shape or of any other desired
form. When with this arrangement the top of the gas chamber is level with that
of the beer chamber, the before mentioned gas supply pipe merely extends in a
loop from the top of the former to the top of the latter, with the before mentioned
regulating cock or valve.

I, VALENTIN LAPP, of Nos. 3 and 4 Kaiser Wilhelm Strasse, Leipzig-Lindenau,
Saxony, Germany, 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:-
My invention relates to apparatus for the conveyance and drawing off of beer
wherein the discharge of the beer is effected by the aid of a pressure chamber filled
with a gas, preferably carbonic acid, at comparatively low pressure, which chamber
communicates with the receptacle containing the beer.
This apparatus serves as a vessel for the conveyance of beer for domestic use;
it is preferably constructed as follows:
A cylindrical or other shaped vessel, adapted to contain the beer, has fixed on
its coned or tapering upper end a closed chamber of smaller diameter, for containing
gas under pressure, such as carbonic acid.
The beer chamber may have, for example, a capacity of about 5 quarts, and the
gas chamber a capacity of about 3 pints. In the beer chamber a pipe leads from
a drawing off cock at the upper part down to close to the bottom; the cock may
have its orifice closed by a cap for preventing dripping.
For catching drippings from the cock when drawing off, a shallow tray extending
partly round the beer chamber may be fixed on the outer surface thereof underneath
the cock.
For filling the beer chamber an opening is provided on the coned or tapering
upper end, which is closed hermetically by a screw stopper, situated at the same
level with the gauge mark, so that it is only possible to fill the vessel with the
exact measure of beer.
I will describe the said apparatus with reference to the accompanying drawings
in which Fig. 1 shews a vertical section and Fig. 2 a plan of one construction in
which the vessel a serves for containing the beer, while the vessel b combined
therewith serves to contain the carbonic acid.
The vessel a can be made of a capacity equal to about 5 quarts while the vessel b
has a capacity of about 1 quarts of carbonic acid of low pressure but other
suitable capacities can be taken. In the beer vessel is a discharge pipe c reaching
down to the bottom, the upper end of this pipe being conuected to a discharge
cock d. For catching any dripping beer a tray f may be fixed to the vessel a
extending about half round it. For filling the vessel a hermetically stoppered
opening g is provided.
The gas chamber 6 constitutes a separate part and is made of such a size
relatively to the capacity of the beer receptacle a that a charge of gas (carbonic

page_text: acid) of low pressure, such as about 1 to 2 atmospheres, is sufficient for forcing
out the whole of the beer. This chainber b can be soldered or otherwise fixed to
the vessel a. For conducting the carbonic acid from 6 into a, a tube h is provided
the part of which outside the vessel b is provided with a closing device or a pressure
reducing device l.
Such external part also has a branch k with cock for connection with a conduit
for the introduction of fresh charges of carbonic acid into the vessel 6 from a
Buitable supply.
The pipe is conveniently led through the vessel b and can be provided at its
entrance into the vessel a with a check valve. This arrangement of the pipe h
protects the same against fracture or damage when cleaning or transporting the
apparatus.
The pipe h can however also be arranged outside the chamber 6 if the above
advantages are not desired, as indicated by dotted lines at ³.
The whole of the part of the pipe outside the chamber b provided with the
pressure reducing device and the gas charging cock, is fixed to the chamber b in
such manner as to be readily removeable therefrom. On the chamber 6 there is
provided in addition to the above devices a hermetically closed opening i for the
discharge of water. The can is provided with a looped pivotted handle m.
At the bottom the apparatus is provided with a circular rim of brass or other
material serving as a stand. The receptacles are preferably made of metal such
as sheet copper, tinned inside and coated with enamel lack in order to prevent all
contamination of the contents.
The drawing off of the beer from the above apparatus is effected by opening the
tap d whereupon the pressure from the carbonic acid chamber will force out the
beer, the carbonic acid flowing into the vessel a in proportion as the beer flows out,
the gas passing from the chamber 6 through the pipe through the opened valve
or reducing device l, and through the check valve into a, where its pressure
drives the beer up the pipe c to the cock d. This action takes place as often as
the cock d is opened, until the whole of the beer is discharged from a.
The pipe c and cock d are made sufficiently small, and with reduced discharge
nozzle to prevent the beer from frothing unduly on issuing.
By making the apparatus of metal as described it can be cleaned by steam, which
is of particular importance for giving good clear beer.
The discharge pipe c is fixed, this arrangement enabling it to be fixed perfectly
air tight to the side of the vessel. The discharge cock is fixed on the upper
conical part a¹ of the vessel a, so that it does not project materially and is thus
better protected against damage.
Instead of arranging the gas receptacle on top of the beer vessel, it may be
arranged at the side, the pipes h h or h³ being suitably altered as shewn by way of
example diagrammatically at Fig. 3 or as at Fig. 4 the form thereof being adapted
to the form of the beer vessel. The latter can also be made either cylindrical or
in barrel form &c. as indicated, and the gas receptacle, as also the pipe connections,
the discharge pipe and cock &c. can be suitably adapted to such forms.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. Apparatus for conveying and drawing off beer, consisting of a beer vessel a,
and receptacle 6 for gas under pressure combined therewith, having a gas supply
pipe which is partly outside the gas receptacle and partly passes through the
same, the external part being removeable and provided with a shut off or
reducing appliance as also with a branch with cock or valve for the supply of gas
under pressure to the vessel b, substantially as described.
2. In apparatus such as is referred to in the first claim, arranging the gas supply
pipe h³ from the vessel 6 to the vessel a entirely outside the former, substantially
as described.

page_text: 3. Apparatus for conveying and drawing off beer, combined and arranged as
herein described with reference to the drawings.
