Improvements in Jugs or Vessels for Oarrying or Containing
Beer and the like.
We, HEINRICH REISSING of 79 Landsbergerstrasse, and ALFRED NEUMANN
of 84 Charlottenstrasse, both in Berlin in the Empire of Germany, Merchant and
Banker respectively, do hereby declare the nature of this invention and in what
manner the same is to be performed, to he particularly described and ascertained
in and by the following statement :-
This invention has for its object an improved form of construction of the jug
or vessel described in our previous Patent No. 15878 of the 23rd August 1895.
The improvement consists essentially in providing the lid or cover of the jug or
vessel with a draw-off tap, a carbonic acid bottle, the main part of which bottle
projects into the interior of the jug or vessel, a regulating valve and a safety valve,
the ice holder or cylinder described in our previous patent being omitted.
In Patent No. 15878 of 1895, the spindle of the valve regulating the supply of
carbonio acid to the jug, is extended to close up to the plug of the cock, and is
operated by means of a cam from the latter, whilst in the present form of construc-
tion this valve is replaced by another, entirely, automatic in its action. The supply
of carbonic acid from the carbonic acid bottle to the jug or vessel is regulated by
this valve in such a way that carbouic acid can only pass into the jug or vessel
when the pressure in the latter has reached a certain degree, for instance Yo
atmospheres.
The improved arrangement and construction of valve is shown in the accom-
panying drawing.
The regulating valve H consists more particularly of the arrangement of two
levers a bacting one against the other. The lever a is pivotted to the valve casing
at a', and presses on the valve body c which closes the opening d through which
the carbonic acid escapes from the bottle, E. The lever bis pivotted on a fork f
connected with an indiarubber diaphragm y against which diaphragm a spring h
presses, said spring being adjustable to a given pressure and counterbalancing the
pressure on the opposite side of the diaphragm. The free ends of said levers a and b
are held together by a suitable spring i, and sot screw k.
As soon as beer is drawn from the jug or vessol and consequently the pressure in
the interior of the valve casing diminishes, the spring prosses the indiarubber
diaphragm g together with the fork inwards (in the drawing to the right), and
the free end of the lever b outwards (in the drawing to the left). The lever a
follows this movement and allows the valve c to open and the carbonic acid to flow
from the bottle E into the jug or vessel, A, until the pressure in the said jug or
vessel has again attained the normal degree.
It must however, bo expressly understood that we do not limit ourselves to the
exact form of valve hereindescribed and shown as it may be replaced by any
other suitable valve without departing from the essential feature of the invention.
In order to prevent the jug from bursting or cracking owing to excessive
pressure, a safety valve is provided on the same. Said valve consists of a
nozzle z on which a nut z', open at the top and having suitable flanges, is sorewed,
between which an iudiarubber disc or washer is held. The nut is also open
above and allows the indiarubbor disc or washer to spring out, if the pressure in
the jug or vessel becomes excessive.
Of course we do not limit ourselves to this precise form of safety valve, but
any similarly acting one may be employed. The lid or cover of the jug or vessel

page_text: may also be provided with suitable appliances, such for instance as a manometer or
the like.
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-
tight cover in combination with a draw-off tap, a carbonic acid bottle, a regulating
valve, and a safety valve, substantially as hereinbefore described and shown in the
accompanying drawing.
2. In a jug or vessel for carrying or containing beer and the like, a supply
regulating valve consisting of two levers acting against one another, and an
adjustable spring acting on a diaphragm connected with the pivot of one of Baid
levers, substantially as hereinbefore described and shown, and with the object set
forth.
Dated this 27th day of August 1896.
