We, HEINRICH DRÄGER, Manufacturer, trading as Lübecker Bierdruckapparate
und Armaturenfabrik Heinr. Dräger, of Lübeck, in the German Empire, and
RUDOLF THIEL, Manufacturer, trading as Carl Thiel & Söhne at the saine place,
do hereby declare the nature of this invention to be as follows:-
This invention has for its object to provide a vessel or receptacle for the
preservation, transport or shipment, and sale on draught of beer and other liquors
enabling the contents of the said vessel to be drawn off or discharged under the
pressure of gas, such as carbonic acid gas, and permitting of the utilization of the
said carbonic acid gas, also as a means for isolating and protecting such liquor
from injurious atmospheric influences.
Apparatus or appliances which have been hitherto employed commercially for
gradually drawing off or retailing beer and the like, such as carbonic acid gas-
syphons, carbonic acid gas receivers, with the piping appertaining thereto, barrels
or kegs with the accessory piping coiled coolers and bar taps, are according to this
invention modified and combined in such a manner as to obtain a handy and
convenient vessel or receptacle, rendering the transport, preservation and sale on
draught of beer or other liquors simple and easy, the improved vessel or receptacle
being filled with the liquor and the necessary quantity of gas, such as carbonic acid
gas (and ice if required) before it leaves the brewery, and being then ready for
delivery at private houses or other establishments, and for immediate use at
any time.
The chief peculiarity of this invention is, that the vessel, which actually contains
the liquor, it is desired to keep on draught, is wholly or partly, encased in the
receiver of gas under pressure, so that the liquor itself is effectually protected from
any injury, either by shocks, or vibration, or through atmospheric influences; the free
space, or capacity of the receiver of gas being preferably equal to the inner capacity of
the liquor-containing vessel, the object being to enable gases at low pressure to be
utilised in filling the pressure chamber and in producing the draught necessary for
retailing the liquor.
The two chambers, the one forming the vessel for the liquor to be preserved or
retailed, and the other constituting the receiver for the gas under pressure-may
be of cylindrical or any other suitable shape, the only essential condition being that
the liquor-containing vessel should be enclosed or partly enclosed within the jacket,
in such a manner that the intervening space between the said jacket and liquor
chamber forms a receptacle for storing and keeping in readiness the varbonic acid
gas, which is necessary to enable the liquor to be drawn off and which need be
subjected to but small pressure. The capacity of the gas receiver is made as
nearly as possible equal to that of the liquor-vessel in order to avert as far as
possible any danger of bursting and then in accordance with Marriott's law, the
liquor may be evacuated with the pressure of only one atmosphere.
As a rule the two chambers are entirely independent of and separated from each
other for convenience, not only in cleaning the liquor receptacle, but also in filling

page_text: it with liquor and in filling the pressure chamber with the gas, as these operations
should be performed separately.
Such an arrangement facilitates also the transport of the liquor, by obviating
any possibility of the gas intended to create the requisite pressure, being absorb:1
by the liquor say in consequence of concussion.
In these cases only, where the pressure proves to be insufficient for drawing the
liquor, should more gas be added to that contained in the jacket. For this purpose,
n valve or cock adapted to be operated by hand, should be momentarily opened.
It is characteristic of this invention that the chambers, arranged in the manner
described, answer the additional purpose of affording a means for instantly
counteracting any tendency of the gas pressure to become neutralized by a
transfer of gas to the liquor. Hence it follows that there at all times prevails in
the gas receiver a considerably higher pressure than that, which exists in the liquar
vessel.
Apart from accessory fittings, the two vessels or chainburs, when once combined
preferably constitute one connected whole, adapted to be bodily carried from place
to place. Both vessels are preferably made of metal, but if desired the inner
vessel may be made of glass, porcelain, enamelled iron or other similar substance,
and may be arranged so as to be removable from the surrounding jacket.
A sufficient portion of the wall of the liquor vessel may be left uncovered by the
gas receiver, for the purpose of fitting thereto the gas transferring valve or other
accessory devices, such as the cooling coil or the like.
The method of filling the two vessels or chambers with liquor and gas
respectively, forms no part of this invention, nor does the method of discharging
either of them, nor indeed the construction of any of the devices or fittings
employed for these purposes separately considered.
The vessels may be provided with additional appliances such as the particular
circumstances of each case may require, say for example, a cooling pipe extending
into the liquor.

and
Improvements in Vessels or Receptacles for the Preservation and
Transport and the Sale on Draught of Beer and other
Liquors.
We, HEINRICH DRAGER, Manufacturer, trading as Lübecker Bierdruckapparate
und Armaturenfabrik Heinr. Dräger, of Lübeck, in the German Empire, and
RUDOLF THIEL, Manufacturer, trading as Carl Thiel & Söhne, at the same place,
do hereby declare the nature of said invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement:-
Our invention relates to vessels or receptacles for the preservation, transport or
shipment and sale on draught of beer and other liquors; and the object of our
invention is, first, to enable the contents of the said vessels to be drawn off or
discharged under the pressure of gas, such as carbonic acid gas, carried by the
vessel in an ordinarily separated chamber; secondly to permit of the utilization of
the said carbonic acid gas also as a means for isolating and protecting such liquor
from injurious atmospheric influences, external shocks and the like.
According to our invention, apparatuses or appliances, hitherto commercially
employed for gradually drawing off or retailing beer and the like, such as carbonic

page_text: acid gas-syphon carbonic acid gas receivers with the piping appertaining thereto,
barrels or kegs with the accessory piping, coiled coolers, bar taps and so on, are,
corresponding to the new purpose, modified and combined in such a manner as to
obtain a handy and convenient vessel or receptacle, rendering the transport,
preservation and sale on draught of beer or other liquors simple and easy; the
improved vessel or receptacle being filled with the liquor and the necessary
quantity of gas (and ice, if required) before it leaves the brewery and being then
ready for delivery at private houses or other establishments and for immediate use
at any time.
A chief peculiarity of this invention is that the vessel which actually contains
the liquor it is desired to keep on draught, is wholly or partly encased in the
receiver of gas under pressure, so that the liquor itself is effectually protected from
any injury, either by shocks or vibration or through atmospheric influences; the
free space or capacity of the receiver of gas being preferably equal to the inner
capacity of the liquor-containing vessel, for the reason to enable gases at low
pressure, that is to say, less than two atmospheres, to be utilized in filling the
pressure chamber and in producing the draught necessary for retailing the
liquor.
A vessel or receptacle comprising these improvements is represented in
the accompanying drawing, in which
Fig. 1 is a sectional elevation of the vessel;
Fig. 2 a sectional elevation of a modified form thereof, and
Figs. 3 and 4 drawn to a smaller scale illustrate in sectional plan two forms of
combination of the vessels or receivers encased one in the other.
The two chambers A and B-the one (A) forming the vessel for the liquor to
be preserved or retailed, and the other (B) constituting the receiver for the gas
under pressure may be of cylindrical or any other suitable shape, the only
essential condition being, that the liquor-containing vessel A should be enclosed
(see Fig. 3) or partly enclosed (as shown in Fig. 4) within the jacket B, in such a
manner, that the intervening space between the said jacket and liquor chamber
forms a receptacle for storing and keeping in readiness the carbonic acid-gas,
which is necessary to enable the liquor to be drawn off and which need be
subjected to but small pressure, say, less than two atmospheres. The capacity of
the gas receiver B is made nearly equal to that of the liquor vessel A, in order to
avoid as far as possible any danger of bursting and then, in accordance with
Mariotte's law, the liquor may be evacuated by pipe o with the pressure of only
one atmosphere. V is a tap to draw off the liquor in retailing it, or for other use,
and for enabling a complete emptying of vessel A there is arranged an escape-
valve E in the pipe u, as shown in Fig. 1.
As a rule both the chambers A and B, which are connected by a common cover
plate C (Fig. 1) are otherwise entirely independent of and separated from each
other, for convenience not only in cleaning the liquor receptacle, but also in filling
it with liquor and in filling the pressure-chamber with the gas, as these operations
should be performed separately. Such an arrangement facilitates also the
transport of the liquor by obviating any possibility of the gas under pressure being
absorbed by the liquor-say, in consequence of concussions.
In those cases only, where the pressure proves to be insufficient for drawing off
the liquor, more gas should be added from that contained in the jacket B.
For this purpose a valve or cock V arranged in a pipe a communicating with both
the chambers A, B and adapted to be operated by hand, should be momentarily
opened.
It is a characteristic of this invention, that the chambers, arranged in the
manner described, answer the additional purpose of affording a means for always
counteracting any tendency of the gas pressure to become equalized by a transfer
of gas to the liquor. Hence it follows, that there at all times prevails, in the gas
receiver, a considerably higher pressure, than that which exists in the liquor
vessel.

page_text: Apart from accessory fittings, the two vessels or chambers A and B, when once
combined, preferably constitute one connected whole, adapted to be bodily carried
from place to place. Botli vessels are preferably made of metal, but, if desired,
the inner vessel may be arranged removable from the surrounding jacket. and
moreover may be made of glass, porcelain, enamelled iron or other similar
substance.
A suflicient portion of the wall of the liquor vessel A, such as the cover C, may
be left uncovered by the gas receiver B, for the purpose of fitting thereto the
pipe o with tap for drawing off the liquor, the gas transferring pipe and
valve V, or other accessory devices, such as the cooling coil R (shown in dotted
ines in Figs. 1 and 2) or the like.
The method of filling the two vessels or chambers with liquor and gas
respectively, forms no part of this invention, nor does it the method of discharging
either of them, nor indeed the construction of any of the devices or fittings
employed for these purposes separately considered.
The vessels may be provided with additional appliances, such as the particular
circumstances of each case may require.
We are aware, that prior to our invention receptacles have been made which
consist of a double-walled vessel both chambers thereof always being connected to
equalize pressure and prevent the whole apparatus from exploding. We therefore
do not elnim such a combination broadly.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
In a transportable vessel for the preservation and the sale on draught of beer
and other liquids, the combination of an inner chamber A and an outer chiniiber B
containing gas of low pressure, and extending about the inner chamber, with an
outer pipe connecting the chambers and the valve V in said connection for
opening the pipe , if required, substantially as described.
