Cassel in the Empire of Germany, Manufacturers.)
I, WILLIAM PHILLIPS THOMPSON F.C.S., M.I.M.E., of the Agency for Foreign
Patent Solicitors; 6, Lord Street, Liver pool, and 6, Bank Street, Manchester, both
in the County of Lancaster; 118. New Street, Birmingham in the County of
Warwick and 322, High Holborn in the County of Middlesex, Civil Engineer, 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 improved jug for pouring out beer and other liquids is provided with a
removable air-tight lid to which the carbonic acid cylinder with its reducing valve
it attached, also a cylinder capable of being filled with ice from the outside and the
drawing off tap and discharge pipe which is carried in a coil through the cooling
cylinder.
The jug is shown in the accompanying drawings,
Figure 1 being a side view partially in section, and
Figure 2 a plan view,
Figure 3 is a horizontal section of the reducing valve, the carbonic acid recep-
tacle and the filling valve of the same,
Figure 4 a vertical section of the safety device.
The vessel A which is made of some suitable material is provided with a lid or
cover B which is rendered air-tight against the vessel by means of a washer ring.
A carbonic acid container C is mounted on the lid and extends into the vessel
which container is provided with a filling valve D and reducing valve E. The
special construction of this reducing valve is shown in Figure 3. A passage a
leading from the carbonic acid vessel C into the valve case is closed by means of a
valve 6 against which bears a lever.c pivotted on a bolt d. A lever e revolubly
connected with a diaphragm g bears against this lever d, and engages in a fixed
curved piece f. A spring h which may be adjusted to a given pressure by means of
a screw i bears from the outside on the diaphragm 9. An indiarubber pipe F
leads from the interior of the valve case in which the levers ce are arranged to a
nozzle Garranged on the lid B through which nozzle the carbonic acid at a
diminished pressure passes into the vessel A. By means of this reducing valve the
pressure existing in the vessel A may be exactly regulated.
A cooling cylinder H provided with a lid L is mounted on the lid B through
which cylinder the discharge pipe J leading to the draw off tap K is passed in one
or more coils. The cooling cylinder H may be filled from the outside with ice
so that the beer or other liquid flowing through the pipe J is effectively cooled.
In order to prevent any bursting of the vessel A by excess pressure in case of the
reducing valve ceasing to act, a safety nozzle M is also arranged on the lid and has
its upper opening closed by a diaphragm N fixed by means of a screwed cap M¹.

page_text: If through any circumstance the pressure in the vessel A becomes too great this
diaphragm is burst or drawn from under the nut M' so that the carbonic acid can
escape from the vessel A.
Having now particularly described and ascertained the nature of the said in-
vention and in what manner the same is to be performed; as communicated to me
by my foreign correspondents I declare that what I claim is:-
A jug for beer and other liquids characterised by a vessel (A) having an air-
tight fitting lid (B) on which a carbonic acid receptacle (C) provided with a
filling valve (D) and a reducing valve (E) is mounted together with a cooling
cylinder (H) through which is passed the discharge pipe (J) leading to a draw off
tap (K) which is also mounted on the lid, and finally a safety nozzle (M) the
diaphragm (N) of which is adapted to burst or be driven outward on the pressure
becoming too great, substantially as hereinbefore described and shown.
