Improvements in Jugs or Vessels, for Carrying or Containing Beer.
and the like.
We, ALFRED NEUMANN of 84 Charlottenstrasse and HEINRICH REISSING of
13 Lessingstrasse, both of Berlin in the Empire of Germany Banker and Merchant
respectively, do hereby, declare the nature of this invention to be, as follows:-.
It is a well known fact that really good and fresh beer can only at present be.
obtained at the breweries themselves,.or in restaurants where the beer is drawn
directly from the cask. For household use, people must always be satisfied with.
the much less. palatable and agreeable, bottled beer, or must fetch beer in open
jugs from the places where the same is. drawn from. the cask.
In such jugs
however the beer very soon becomes flat and loses its good taste owing to its
long contact with atmospheric air. It is much too, inconvenient. to procure an
entire cask for a household, and further beer even in the cask does not keep long
without the necessary. carbonic acid apparatus after some has been drawn off.
These drawbacks are removed by the improved, beer, jug or vessel, which forms
the object of this invention.
The invention consists of a jug or vessel for conveying beer, which jug is more.
particularly intended / household use, and in, which, the beer keeps fresh and
palatable for several ys, even when some of the beer, is drawn off at various :
times from the same.
The invention cop
a beer jug or vessel
イ
ts essentially in securing in an air-tight manner a cover on
rmed of any suitable material, which cover is provided with.
an entire beer appa tus consisting of a draw-off tap, an ice holder projecting into
the jug, a cooling p.pe. or, worm connected, with the ice holder and running to the:
draw-off tap, and a carbonic acid bottle, which also projects into the interior,
of the jug, and from which the carbonic acid is conveyed into the interior of the
jug by an automatically self-adjusting feeding device.
These
The jug, is formed. of glass, earthenware or any other suitable material. It is,
cl sed by a cover plate which is rendered tight.by means of an indiarubber ring,
or washer, and is tightened up. or secured by means of three screws.
screws are pivotally connected at their lower ends to a metal ring, which is lodged,
in a small groove in the neck of the vessel. On the upper cover plate of the jug,
a draw-off tap or cock is arranged, with a pipe running to the bottom of the jug..
This
An ice-holding vessel inserted in the jug serves for cooling the beer.
holder consists of a wide metal tube, closed at the bottom, and having its upper
end let into a suitable opening in the cover plate of the jug and attached thereto.
The upper open end of the ice holder is closed by suitable lid or cover.
The pipe
leading to the draw off tap forms a cooling worm in the ice holder and is for this.
purpose put up into the ice holder and down again in the form of a curve.
A carbonic acid bottle made of compressed steel is also inserted in the cover plate
of the jug and is screwed into the said cover plate in such a way that its lower
end projects into the interior of the jug. At the upper end of the carbonic acid
bottle is au inlet valve, the casing of which is screwed into the side of the
carbonic acid bottle and has a central bore which widens towards the upper end.
In this bore is a valve spindle which has at its under end a knob or button and
another at its upper end. A spring is coiled round the upper end of the spindle,

page_text: and presses with one end against the upper button or knob, and with the other
bears against a seat, which is formed by a narrowing of the valve bore. A screwed
cap on the valve casing protects the device externally.
In order to convey carbonic acid through the inlet valve into the carbonic acid
receiver or bottle, the outer cap is taken off, and the inlet valve is connected with
a carbonic acid supply. The pressure of the carbonic acid then presses the lower
knob, inwards against the pressure of the spring, and carbonic acid can thus enter
the bottle. When the filling is completed, the valve closes itself automatically
as soon as the pressure in the interior of the bottle in combination with the
pressure of the spring has become greater than the outside pressure (that is than
the pressure of the carbonic acid contained in the supply vessel). After the
bottle has been removed (unscrewed) from the supply bottle the valve case is closed
by screwing on the outer cap.
The lower knob of the valve spindle is preferably screwed on the spindle which
is threaded and may be adjusted on the same in order to impart any desired
pressure to the spring. The transfer of carbonic acid from the carbonic acid
bottle to the interior of the jug is regulated by means of a second valve. This
consists of a valve case which is screwed into the top of the carbonic acid vessel
and above which is placed a spring case. The latter is screwed on to the valve
case by means of a screwed cap or sleeve having an internal flange. An india-
rubber diaphragm is strained firmly between the valve case and the spring case.
In the centre of the valve- and spring-cases is a valve spindle. This is passed
through the diaphragm and firmly connected therewith by means of two screw
nuts. A spring presses on the upper nut, which spring may be tightened or
loosened by means of a screwed stop according to requirements. At the lower
end of the valve spindle is a conical plug or stopper. This fits exactly on the
valve seat formed in the under end of the valve case, which seat is preferably
made of vulcanite. A small sieve is arranged under the conical valve plug, and
has for its object to retain any particles of dust contained in the carbonic acid
bottle. At the upper end of the valve spindle is a press button. A short tube
connects the interior of the valve case with the interior of the jug, and when the
conical valve plug is opened, the carbonic acid passes into the valve case and
flows from there through a nipple into the above mentioned short tube, and thus
into the jug.
The regulation of the supply of carbonic acid takes place automatically by
means of the valve; the spring over the diaphragm tends to press the valve spindle
together with the conical valve plug downwards, and the carbonic acid can enter
the space beneath the diaphragm and from thence pass through the nipple and the
short pipe into the jug or vessel. As soon however as the pressure under the
diaphragm has, through the carbonic acid flowing out of the bottle, become greater
than the counter pressure of the spring, the carbonic acid presses the diaphragm
together with the valve spindle and the conical plug upwards, and consequently
closes the valve. Only when beer is drawn from the jug, and the pressure in the
same consequently diminishes, does the action of the spring again come into play
and open the valve. The process previously described is then again repeated. In
case the automatic supply of carbonic acid for some cause does not work it is only
necessary to press on the external button in order to open the valve.
A dripping-cup
preferably arranged on the draw off cock of the beer jug.
This is so attached to the plug of the cock that it must move with the cock and
when the same is opened, at once simultaneously turn to one side. This dripping-
cup device consists of a spoon-shaped cup attached to a loop piece screwed on the
under end of the plug of the tap. The under arm of this loop piece is preferably
so arranged that it forms a channel in which the liquid which escapes at the screw
at the lower end of the tap plug can run into the spoon.
The dripping-cup device is arranged in such a way that it can simultaneously
act as a check against any unauthorized drawing-off of the beer. For this object.
it is adjustably arranged on the loop piece, and the shank of the spoon is forked.

page_text: and provided with eyelets, at the end, through which a cord may be passed, to
which a seal is attached.
If then it be desired to secure the tap against any unauthorised opening, the
spoon is pushed back to the right, so that the two arms of its fork-shaped shank
embrace the neck of the cock, the two ends projecting on the other side. A cord
may then be easily drawn through the eyelets and a seal attached thereto.
In
Another form of construction of the beer jug differs from that previously
described in the means of conveying the carbonic acid from the carbonic acid
vessel into the jug, and in the arrangement of the necessary regulating valve.
this case the regulating valve is not, as in the previous form of construction,
placed vertically on the carbonic acid bottle, but horizontally on the side of the
latter. In this second form of construction the valve spindle is further preferably
securely connected with the plug of the cock. This device for connecting the
spindle and the cock consists of a curved slotted guide piece formed on the plug
of the cock, the slot in this guide piece running mainly concentrically with the
plug of the cock. The guide slot runs outwardly a little from its seini-circular
shape at one end. A pin attached to the end of the valve spindle engages in the
slot. When the tap is turned, the pin slides in the guide slot without pushing
the valve spindle. Only when the cock is brought round so far that the pin enter
the eccentric or extended part of the slot, is the valve spindle together with the
valve plug or case pushed back, and thereby the valve opened so that carbonic
acid can pass to the right side of the diaphragm, and from thence flow into tho
jug. In the arrangement just described of the connection of the valve with the
cock, the automatic adjusting device and therefore also the spring thereof described
in the first form of construction is omitted.
The same device however may with slight modification be adapted for automatic
self regulation. Instead of connecting the valve spindle by means of a slotted
guide with the cock, a cam may be formed on the cock plug, whereby the valve
spindle may be moved, on the cock reaching a given angular position. Until
however the cam comes in contact with the valve spindle, the regulation of the
supply of carbonic acid takes place automatically in the same manner as herein-
before described, by means of a spring, which is arranged in the valve case on the
outer left hand side of the diaphragm. A spring is arranged on the other side of
the diaphragm hut may however be entirely omitted and has for its object to act
against the pressure of the cam.
Finally the apparatus has a safety valve of the ordinary kind, which opens, and
allows a portion of the carbonic acid coutained in the jug to escape, as soon as the
pressure becomes too great. The beer jug is preferably filled with the lid or cover
plate closed. The cock of the jug is connected by means of a short flexible pipe
with the tap of the cask from which the beer is to be drawn. The beer can then
flow into the jug through the tube without foaming. Before filling the jug it is
advisable to expel all the air from the same by letting in some carbonic acid, in
order that the beer shall not come in contact with atmospheric air.

COMPLETE SPECIFICATION.
Improvements in Jugs or Vessels for Carrying or Containing Beer
and the like.
We, ALFRED NEUMANN of 84 Charlottenstrasse, and HEINRICH REISSING
of 13 Lessingstrasse, both of Berlin in the Empire of Germany, Banker and
Merchant, respectively, do hereby declare the nature of this invention and in what

page_text: manner the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
It is a well known fact that really good and fresh beer can only at present be
obtained at the breweries themselves, or in restaurants where the beer is drawn
directly from the cask. For household use, people must always be satisfied with
the much less palatable and agreeable bottled beer, or must fetch beer in open jugs
from the places where the same is drawn from the cask. In such jugs however
the beer very soon becomes flat and loses its good taste owing to its long contact
"with atmospheric air. It is much too inconvenient to procure an entire cask for a
household, and further beer even' in the cask does not keep long enough without
the necessary carbonic acid apparatus after some has 'been drawn off. These
drawbacks are removed by the improved beer jug or vessel' which forms the object
of this invention.
The invention consists of a jug or vessel for conveying beer, which jug is more
particularly intended for household use; and in which the beer or other liquid
which becomes flat 'on exposure to the 'air, keeps fresh and palatable for several
days, even when some of the beer, or the like, is drawn off' at various times 'from
the same.
The invention consists essentially in securing in an air-tight manner a cover on
a beer jug or vessel formed of any suitable material, which cover is provided with
an apparatus consisting of a draw-off tap, an ice holder projecting into the jug, a
cooling pipe or worm connected with the ice holder and running to the draw-off
tap, and a carbonic acid bottle, which also projects into the interior of the jug, and
from which the carbonic acid is conveyed into the interior of the jug by an
automatically self-adjusting feeding device and a safety valve.
In the accompanying drawings,
Figure 1 is a vertical section of the jug or vessel;
Figure 2 is a vertical section of the upper part of the carbonic acid bottle,
together with the inlet valve arranged at the upper end of the same and the valve
for regulating the transfer of carbonic acid to the jug or vessel;
Figure 3 is a partial vertical section of a modified form of construction;
Figure 4 is a detail of Figure 3;
Figure 5 is a plan view on a larger scale of a dripping cup device employed with
the form of construction shown in Figure 1.
The jug A is formed of glass, earthenware, or any other suitable material. It
is closed by a cover plate B which is rendered tight by means of an indiarubber
ring or washer b'and is tightened up or secured by means of three screws.c. These
screws are pivotally connected at their lower ends to a metal ring d'which is lodged
in a small groove in the 'neck'of the vessel. On the 'upper cover plate B of the
jug, a draw-off tap or cock C is arranged, with a pipe frunning to the bottom of
the jug. An ice-holding vessel 'D'inserted in the jug serves for cooling the beer
or other liquid. This holder consists of a wide metal tube, closed at the bottom
and having its upper end let into a suitable 'opening in the cover plate of the jug
and attached thereto. The upper open end of the ice holder is closed by a suitable
lid or cover g. The pipe leading to the draw off tap forms a cooling worm f¹ in
the ice holder and is for this purpose bent up into the ice holder and down again
in the form of a curve. A carbonic acid bottle E made of compressed steel is also
inserted in the cover plate of the jug and is screwed into the said cover plate in
such a way that its lower end projects into the interior of the jug. At the upper
end of the carbonic acid bottle is an inlet valve H, the casing h (Figure 2) of
which is screwed into the side of the carbonic acid bottle and has a central bore h¹
which widens towards the upper end. In this bore is a valve spindle i which has
at its under end a knob or button and another at its upper end. A spring i
is coiled round the upper end of the spindle, and presses with one end against the
upper button or knob and with the other bears against a seat, which is formed
by a narrowing of the valve bore. A screwed cap k on the valve casing / protects
the device externally.

page_text: In order to convey carbonic acid through the inlet valve into the carbonic acid
receiver or bottle, the outer cap k is taken off, and the inlet valve is connected
with a carbonic acid supply. The pressure of the carbonic acid then presses the
lower knob inwards against the pressure of the spring and carbonic acid can
thus enter the bottle 'B. When the filling is completed, the valve closes itself
automatically as soon as the pressure in the interior of the bottle B in combination
with the pressure of the spring 3 has become greater than the outside pressure
(that is than the pressure of the carbonic acid contained in the supply vessel).
After the bottle B has been disconnected (unscrewed) from the supply bottle the
valve case is closed by screwing on the outer cap k..
The lower knob of the valve spindle i is preferably screwed on the spindle which
is threaded and may be adjusted on the same in order to impart any desired
pressure to the spring. The transfer of carbonic acid from the carbonic acid
bottle B to the interior of the jug A is regulated by means of a second valve F.
This consists of a valve case F1 (Figure 2) which is screwed into the top of the
carbonic acid vessel and above which is placed a spring case F'. The latter is
screwed on to the valve case Fl by means of a screwed cap or sleeve F' having an
internal flange l. An indiarubber diaphragm m is strained firmly between the
valve case Fand the spring case F. In the centre of the valve- and spring-cases
is a valve spindle n. This is passed through the diaphragm and firmly connected
therewith by means of two screw nuts o o¹. A spring p presses on the upper nut o¹
which spring may be tightened or loosened by means of a screwed stop 9 according
to requirements. At the 'lower end of the valve spindle n is a conical plug or
stopper r. This fits exactly on the valve seats formed in the under end of the
valve case, which seat is preferably made of vulcanite. A small sieve t is arranged
under the conical valve plug, and has for its object to retain any particles of
dust contained in the carbonic acid bottle. At the upper end of the valve spindle
is a press button n'. A short tube u connects the interior of the valve case F¹
with the interior of the jug, and when the conical valve plug r is opened, the
carbonic acid passes into the valve case Fl and flows from there through a nipple u¹
into the above mentioned short tube u and thus into the jug A.
The regulation of the supply of carbonic acid takes place automatically by
means of the valve; the spring p over the diaphragm m tends to press the valve
spindle n together with the conical valve plug r downwards, and the carbonic acid
can enter the space beneath the diaphragm and from thence pass through the
nipple u and the short pipe u into the jug or vessel A.
น
As soon however as the
pressure under the diaphragm m has, through the carbonic acid flowing out of
the bottle, become greater than the counter pressure of the spring p, the carbonic
acid presses the diaphragm together with the valve spindle n and the conical plug
upwards, and consequently closes the valve r. Only when part of the contents is
drawn from the jug, and the pressure in the same consequently diminishes, does
the action of the spring p again come into play and open the valve h. The process
previously described is then again repeated. In case the automatic supply of
carbonic acid for some cause does not work it is only necessary to press on the
external button n¹ in order to open the valve.
A dripping-cup is preferably arranged on the draw off cock of the beer jug.
This is so attached to the plug of the cock that it must move with the cock and
when the same is opened, at once simultaneously turn to one side. This dripping-
cup device consists of a spoon shaped cup attached to a loop piece screwed
on the under end of the plug of the tap. The under arm of this loop piece v' is
preferably so arranged that it forms a channel in which the liquid which escapes
at the screw at the lower end of the tap plug can run into the spoon, Figures 1
and 5.
The dripping-cup device is arranged in such a way that it can simultaneously
act as a check against any unauthorised drawing-off of the beer or the like. For
this object it is adjustably arranged on the loop piece ¹ and the shank ³ of the

page_text: spoon is forked and provided with eyelets (Figure 5) at the end, through which a
cord may be passed, to which a seal is attached.
If then it be desired to secure the tap against any unauthorised opening, the
spoon is pushed back to the right, so that the two arms of its fork-shaped
shank embrace the neck of the cock C, the two ends projecting on the other
side. A cord may then be easily drawn through the eyelets and a seal attached
thereto.
Another form of construction of the beer jug is shown in Figure 3 and differs
essentially from that previously described and shown in Figures 1 and 2 in the
means of conveying the carbonic acid from the carbonic acid vessel into the jug,
and in the arrangement of the necessary regulating valve F. In this case the
regulating valve is not, as in the previous form of construction, placed vertically
on the carbonic acid bottle, but horizontally on the side of the latter. In this
second form of construction the valve spindle is extended to close up to the plug of
the cock C¹ and ends in a knob n³. A cam or projecting piece y is formed on the
plug of the cock C₁ at the same level as the knob n². When the tap is turned, the
cam y encounters the knob n² of the valve spindle n and pushes the latter towards
the carbonic acid bottle, thereby opening the valver so that carbonic acid can
pass from the bottle B into the jug A.
The cam y is so arranged that it only encounters the knob n² when the cock is
almost entirely opened.
This arrangement has mainly for its object to admit carbonic acid to the jug
when the pressure in the latter is insufficient. Ordinarily it suffices to only
partially open the cock, so that the cam y does not come in contact with the
knob n; when however the beer or the like iu consequence of insufficient pressure
does not flow with sufficient force or even ceases to flow from the cock C, the
.latter is carefully turned further until the cam opens the carbonic acid valve r.
The same device however may with slight modification be adapted for automatic
self regulation. Until the cam comes in contact with the valve spindle, the
regulation of the supply of carbonic acid takes place automatically in the same
manner as herein before described, by means of a spring, which is arranged in the
valve case on the outer left hand side of the diaphragm. A spring is arranged on
the other side of the diaphragm but may however be entirely omitted and has for
its object to act against the pressure of the cam.
Finally the apparatus has a safety valve of the ordinary kind, which opens, and
allows a portion of the carbonic acid contained in the jug to escape, as soon as the
pressure becomes too great.
The
The beer jug is preferably filled with the lid or cover plate B closed.
cock C of the jug is connected by means of a short flexible pipe with the tap of
the cask from which the beer is to be drawn. The beer can then flow into the jug
through the tube without foaming. Before filling the jug it is advisable to expel
all the air from the same by letting in some carbonic acid in order that the beer
shall not come in contact with atmospheric air.
The beer or the like may be cooled by ice in small pieces being inserted in
the cylinder D. Heat is also absorbed from the beer or the like contained
in the jug by the carbonic acid or the carbonic acid vessel which projects into
the jug.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
⚫claim is :-
1. A jug or vessel for carrying or containing beer and the like, having an air-
tightly closed lid (B) provided with a draw-off tap (C), an ice-holder (D)
projecting into the jug, said ice holder having a pipe (f) running from the bottom
of the jug (A) to the draw-off tap, thus forming a cooling worm (f), a carbonic
acid bottle (E) projecting into the interior of the jug (A) and having an automatic

page_text: regulating valve, and finally a safety valve, for the purpose of enabling the beer
or the like to be cooled as desired in the jug, and kept a long time in a fresh and
palatable condition, even after some of the contents have been drawn off at various
times, substantially as described.
2. In a jug or vessel of the kind described for carrying or containing beer or
the like, an automatic regulating valve, consisting of a valve case (F) arranged
on the carbonic acid bottle, said valve case being divided by a diaphragm into two.
parts (FF), one of which (F1), facing the bottle, is connected by a pipe with
the interior of the jug (A), whilst in the other a spring (p) is arranged, the
pressure of which may be regulated by means of a screw stop (7), which spring
opens a valve (r) and allows carbonic acid to pass into the jug (A) as soon as
the pressure of carbonic acid within the latter has fallen too low, substantially as
described.
3. In a jug or vessel of the kind described for carrying or containing beer or
the like, a valve spindle (n) extended up to the plug of the cock (C¹) and a cam y
formed on said plug on a level with the spindle (n), the whole being adapted to
open, as soon as the cock is entirely opened, an automatic valve (r) and allow
carbonic acid to pass over into the jug (A), whilst when the cock is only partially
opened the regulation of the carbonic acid supply is effected automatically
substantially as described.
4. In the jug or vessel of the kind described for carrying or containing beer,
the arrangement of a dripping-cup device on the draw off cock, consisting of a
spoon-shaped cup (v), which is connected with the cock plug (C) in such a way
that when the cock is opened the dripping cup device is simultaneously turned to
one side, but when the cock is again closed, it is again brought under the discharge
orifice, said dripping-cup device being further provided with a forked shank (v2)
which may be pushed backwards over the end of the neck of the tap for the
purpose of enabling a seal to be attached thereto so as to secure the cock against
unauthorised opening substantially as set forth.
