I, JozÉ
TO ALL TO WHOM THESE PRESENTS SHALL COME,
LUIS, of the British & Foreign Office for Patents, No. 18, Welbeck Street,
Cavendish Square, London, in the County of Middlesex, Patent Agent, send
greeting.
WHEREAS I am in possession of an Invention for "A NEW COOLING
APPARATUS FOR LIQUIDS, ESPECIALLY BEER," and have petitioned Her Majesty to
grant unto me, my executors, administrators, and assigns, Her Royal Letters
Patent for the same, and have made soleinn declaration that the same is a
communication to me from Jean Louis Baudelot, of No. 10, Rue Mogador,
Paris, in the Empire of France:

page_text: NOW KNOW YE, that I, the said Jozé Luis, do hereby declare the
following Complete Specification under my hand and seal, fully describes
and ascertains the nature of the said Invention, and the manner in which the
same is to be performed, reference being had to the accompanying Drawings,
that is to say
The object of the present Invention is the expeditious cooling of liquids,
more especially beer, from boiling, down to any desired temperature. The
apparatus is composed of a certain number of tubes, according to the quantity
of beer to be cooled, and through these tubes, which are joined or commu-
nicate, cold water is made to pass; entering at the bottom, it ascends, aud
passes out heated at the top. The beer, after being boiled, is allowed to rest
a certain time in a receiver, and then it is made to enter a tube which
distributes it in a trough furnished with a fine metallic cloth, which serves to
retain the foreign substances that the beer may contain. The beer, thus
strained, falls into a second trough pierced with a number of small holes,
through which it runs equally distributed over the whole outer surface of the
top tube; and from this it falls to the second tube, less warm from contact
with the beer than the first, and so on till it reaches the receiver in which the
apparatus is placed; whence it is conducted to the tubs or vats for fermen-
tation. The beer can be cooled down to the exact degree of temperature
preferred.
The cold water which enters at the bottom and passes through all the tubes
becomes warmer & warmer, till it escapes from an outlet of the top tube, on
which the boiling beer falls. This water can be used for the different
requirements of the brewery, either for cleaning the vats or for the next brew.
DESCRIPTION OF THE DRAWINGS.
Fig. 1, elevation of a straight tubed cooling apparatus; Fig. 2, side view
where the cold water enters; Fig. 3, elevation of a part of a horizontal
serpentine cooling apparatus; Fig. 4, view of the upper ring or tube; Fig. 5,
elevation of a cooling apparatus, composed of one tube bent in a screw
forin; Fig. 6, horizontal view.
The boiling beer is introduced by the knee pipe a into the tube b, which is
placed in the trough c, d. This tube has holes pierced in it, and distributes
the beer in the trough c, retaining at the same time any foreign substances
that may be in the beer. The trough c is furnished with a very fine metallic
cloth, and the liquid thus strained falls in the distributing trough d, which is
furnished with a single row of small holes which distribute the beer uniformly
on the whole exterior surface of the first tube and then on the second, and so

page_text: on from tube to tube till in the basin e, by which operation it is completely
cooled. The cold water enters in an opposite direction by the tube fat the
bottom of the apparatus,and mounts progressively in the interior of the tubes,
receiving the heat from the beer, and goes out hot at g. The ends of the
tubes are furnished with screws, which can be removed in order to facilitate
the cleaning of the interior of the apparatus.
The Figs. 3 & 4 represent a circular cooling apparatus. The cold water
enters by the knee pipe h, and divides the water to the right & left, when it
enters the second knee pipe i, which divides the water to the right and left
of the tube placed above, and so on till it passes out warm at j. If the water
is required to run always in the same direction, a barrier / could be put at the
left of the knee joint k, and to the left of the barrier would be the knee
joint of the circular tube u above, and so on to the last.
The same principle as that of Figs. 5 & 6 can be applied to an apparatus
having the form of a parallelogram or any other shape instead of round, so as
to suit the different localities in which it may be placed. On the apparatus
are placed the distributing trough a, b, c, d, like those of the Figs. 1 & 2 for
distributing the beer on the whole exterior surfaces of each tube or ring.
The Figs. 5 & 6 represent a cooler composed of a single tube of a screw
shape. m, tube, by which the cold water is introduced at the bottom of the
screw shaped apparatus, and which it ascends by degrees till it escapes at the
outlet o. o, outlet for the water, which has become heated from the beer.
P, screw joints, permitting the cleaning of the apparatus. All the accessory
parts a, b, c, d, e, are adapted in the same manner as for the Figs. 1 & 2, taking
a circular form like the apparatus. The hot beer coming from the boilers
runs as in the Figs. 1, 2, 3, & 4, into a circular trough, which distributes it
uniformly on the whole exterior surface of the apparatus till it arrives com-
pletely cooled at r. In this apparatus the water has a regular ascent, and
meeting with neither knee or joint pipe, experiences much less resistance.
The tubes forming the apparatus can be placed one on the other, or a small
distance can be left between each. If this distance is more than the fourth
of an inch, it is advisable to place a small toothed blade between, as in Fig. 1.
In a cooler of a yard in diameter, as shown by Figs. 5 & 6, the slope of the
tube which composes it, is very slight, and the beer falls but little out of a
perpendicular line in its descent.
The apparatus is made of a metal that is a good conductor of heat, as, for
example, copper, zinc, &c. The thing most essential in the construction of
the apparatus is to make the tubes as small as may be, but at the same
time, that they allow a sufficient quantity of water to pass in equivalent to

page_text: the quantity of beer to be cooled. If seventeen tubes, as in Figs. 1 & 2, or
twenty, as in Figs. 5 & 6, cannot produce the maximum effect, then it is only
necessary to increase the number of tubes to 25, 30, &c. In this case the
apparatus, Figs. 3 &, would be preferable, for supposing it to be three feet
high, with twenty-five tubes placed one above another, it will have double the
effect of the apparatus, Fig. 1, and will use less water in proportion. If the
apparatus above described would not suffice for a large establishment, then
either the number of tubes, or their length, or their diameter can be increased.
If it is desired to cool the beer to a lower temperature, ice is put in a large
reservoir S, Fig. 1, for the water to fall on before entering the tubes, which
may be either round, square, oblong, or oval.
Having thus described the nature of my Invention and the manner in which
the same is or may be carried into effect, I wish it to be distinctly understood
that I do not confine myself to the precise details herein described, as such
may be varied or modified without departing from the principle of action
thereof. What I claim is the system or arrangement with the necessary
accessory pieces, as described in the foregoing Specification with the accoin-
panying Drawings, of a cooling apparatus for liquids, more especially beer.
In witness whereof, I, the said Jozé Luis, have hereunto set my hand
and seal, this 14th day of April, in the year of our Lord One thousand
eight hundred aud fifty-nine.
JOZE LUIS. (L.B.)
