"IMPROVEMENTS IN
HERBERT JOHN HADDAN, of Kensington, Middlesex,
APPARATUS FOR COOLING BEER AND OTHER LIQUIDS," a communication to me
from abroad by Wilhelm Nussbeck, of Berlin, Germany,
This invention has for its object the cooling of beer in casks in a more direct
and economical manner than is usually done, and so as to cool at the samo time
the air which enters the cask.
For this purpose I use chiefly an ice-reservoir preferably situated at the top
of the cask, and a cooling pipe extending from the ice-reservoir through the bung
hole of the cask down to near the bottom of the same, where it may be bent round
horizontally.
A small tube which may be bent or corrugated leads atmospheric air upward
through the ice and allows it to escape near the top of the said reservoir, from
which another narrow tube leads the cold air downward along the cooling pipe
into the cask. A third tube, extending from the bottom of the cooling pipo
upward into the ice-receptacle, allows the spent water to escape from the latter
through a cock in proportion to the melting of the ice.
The reservoir is composed of two casings, the space between which is filled with
a bad conductor of heat, it. is also provided with a cover at the top and a conical
tube which surrounds the upper end of the cooling pipe.

HERBERT JOHN HADDAN, of Kensington, Middlesex "IMPROVEMENTS IN
APPARATUS FOR COOLING BEER AND OTHER LIQUIDS," a communication to me
from abroad by Wilhelm Nussbeck, of Berlin, Germany,
This apparatus for cooling beer in casks has for its object to cool the beer in the
most direct mannor, using the ice required for this purpose in the most rational
way, and at the same time to cool the atmospheric air which enters the cask.
On the accompanying drawing which illustrates the invention, Fig I is a vertical
section of a beer cooler showing its application to a cask, while the other figures
show details and modifications of the saine. The apparatus consists essentially of
a cooling pipe a and an ice reservoir m'. The latter is composed of an exterior
and interior casing made of any suitable material, the space formed between the
two casings being filled with a bad conductor of heat (coal-dust, ashes ctc) The 1
top of the casing is provided with a lid f, hermetically screwed in and also
filled with bad conductors of heat. The cooling pipe a is connected with the
bottom of the ice reservoir and strengthened or stayed by a bevelled jacket g which
serves as a plug for the cask.
In the interior of the ice reservoir m' is situated the air pipe e which may be
bent or corrugated, leading upward along the walls of the reservoir and having
an aperture below the lop of the casing, while it communicates at the bottom with
the atmospheric air.
The ice accumulated round the pipe cools the air before it enters the ice
reservoir. Inside of the ico reservoir a second pipe c, opens at the top like the
first pipo above mentioned, discharges the air into the cask over the level of the
beer and close underneath the plug g. The water discharge pipe, d, leading through
the cooling pipe a, allows the cooling water to escape after use through the cock h,
in proportion as it formed by the melting of the ice. The metallic cooling pipe a,
bent at a right angle, is divided at its lower end by a sieve forming a space i from
which the water discharge pipe leads upward. The sieve prevents impurities to
enter the pipe d. The cooling pipe a is closed at its bent end with a cap which
may be removed for cleansing the apparatus. P is the beer tap.
The whole apparatus is so constructed and made in such dimensions as to be
easily handled, that is to say, filled, emplied, and cleaned. When the apparatus {
is removed, the cock h should be previously turned off to prevent the spilling of
water.
The plug or bung g is provided with a screw thread.
To prevent a constant air current from the beer cock to the cooling apparatus,
and vice-versa, which could spoil the beer, a small valve is enclosed in the air
pipo c, so that the cooled air contained in the pipe a enters the cask by lifting the
valve (Figs III and IIIa) only when beer is being drawn off. At other times the
beer is protected against any contact with atmospheric air.
As soon as beer is drawn off, the air in the cask is rarefied and the clack a
thereby raised so as to admit cooled air from the cooling apparatus m into the cask.
Such a clack or valve may also be placed in the air pipe e. Figs III and IIIa show
the automatically closing air pipe in detail.
The water cock h, discharging the water formed by the melting of the ice
through the hose k, is provided with a small upright air pipe o to prevent the
hose from acting as a syphon and drawing all the water out of the cooling &
pipe a.

page_text: Fig IV shows a modification of the beer-cooling apparatus as used for the casks,
which are standing when on draught, and may be used with so called patent
beer cocks (for instance that patented in Germany under No 3251) or common
beer cocks (with pressure apparatus) the taphole being at the top of the cask. The
shape of the apparatus is adapted to the upright position of the cask.
An automatic closing valve x is used, and to render the cooling apparatus
applicable in combination with a pressure apparatus, the air supply apparatus
is modified in such a manner, that the inlet of air pipe e and the outlet of c
are outside the apparatus. Consequently the latter opening does not directly
communicate with the cask.
The cooled air passes through hose n into the pressure apparatus, is thereby
condensed and finally introduced into the cask by the hose m (or the usual
pressure pipe).
If only the beer and not the air has to be cooled, every exchange of air and loss
of heat may be prevented by shutting the two cocks v and w, the air is then
admitted into the cask through the beer cock or the pressure apparatus which may
also develope carbonic acid, if required. If needed the beer may be drawn off
under the pressure of carbonic acid. For this purpose the air supply pipe e and
the air discharge pipe c are connected with one another by a corrugated pipe 2,
Fig V. The carbonic acid generator is joined to the cock w and the cooled
Carbonic acid conducted directly into the cask, as shown in Fig V. Or else (see
Fig 4, where a pipe coil between the pipes e and c is indicated by dotted lines)
the cock w may be connected with the carbonic acid generator d by a hose n,
and with the cask or beer tap p by a hose m.
The corrugated pipe 2 may also be used with common air-pressure apparatus.
In this case, instead of the carbonic acid generator d', a pressure apparatus is used,
which drives the air through the pipe n to the pipe coil. In the latter the
compressed air is cooled, and escaping at it is conducted into the cask by a
hose or else direct into the cask as shown in Fig V. These modifications of the
hose-pipe conduit may be chosen at will. The sliding post t serves to support the
cooling apparatus.
CLAIMS.
The beer cooling apparatus reaching through the bung hole nearly to the bottom
of the cask, and serving to cool the beer as well as the air which flows in when
beer is being drawn off, substantially as described and illustrated
The use of a valve x in the air conduit for closing the barrel, when no beer is
being drawn off.
3. The arrangement of the two air openings v, w applied to the cooling apparatus
outside the cask, in order to adapt the apparatus for drawing off beer with or
without pressure, and with or without air-cooling.
The combination of a short pipe o open at the top, with a a discharge-cock h
or hose for ice water, in order to prevent the discharge pipe for ice water from
acting as a syphon.
The use of a continuous air-inlet and outlet pipe or coil in the cooling apparatus
in order to draw off beer under pressure when required.
In Witness whereof I the said Herbert John Haddan have hereunto set my hand
nd seal this 16th day of July A.D. 1883.
