Year: 1872

page_text: LETTERS PATENT to Henry Bernoulli Barlow, of Manchester, in the
County of Lancaster, Patent Agent, for the Invention of "In-
PROVEMENTS IN APPARATUS FOB COOLING WORT AND OTHER LIQUIDS.”—A
communication from abroad by A. Naegeli, of Wegeleben, in the
Kingdom of Prussia.
Sealed the 10th October 1872, and dated the 22nd April 1872.
PROVISIONAL SPECIFICATION left by the said Henry Bernoulli Barlow
at the Office of the Commissioners of Patents, with his Petition,
on the 22nd April 1872.
I, HENRY BERNOULLI BARLOW, of Manchester, in the County of
5 Lancaster, Patent Agent, do hereby declare the nature of the said In-
vention for "IMPROVEMENTS IN APPARATUS FOR COOLING WORT AND OTHER
LIQUIDS," a communication to me from abroad by A. Naegeli, of
Wegeleben, in the Kingdom of Prussia, to be as follows:-
This improved apparatus consists of a cylindrical vessel containing
0. any suitable number of concentric compartments made of copper or other

"
metal. These compartments are alternately wide and narrow. The narrow
spaces are closed at the top and bottom, and they are connected below to
the pipe which admits the cold water and above to the discharge pipe;
the wider spaces are open above and below to allow the wort or other
liquid to be cooled to fill them. At the bottom of the apparatus is a
side pipe with an upright discharge pipe, and a valve which when closed
causes the cooled wort to run off through the upright discharge pipo
and down an open mouthed pipe into the fermenting vat. So long as
the hot wort is pumped into the cooling apparatus the valve above
referred to is closed, and the cooled wort flows off at the discharge pipe,
and the cold water flows up through the narrow spaces from the lower
to the upper end of the cooling vessel, but when the pumping of the hot
wort ceases the valve is opened to allow the cooled wort to run off.
Above the cooling apparatus is a vertical pipe with horizontal perforated
arms; the water for rinsing out or cleaning the apparatus is let into the
vertical pipe, and in escaping through the perforations in the horizontal
arms it causes them to revolve, thus distributing the water over the'
whole apparatus.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Bernoulli Barlow in the Great Seal Patent
Office on the 22nd October 1872. .
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
BERNOULLI BARLOW, of Manchester, in the County of Lancaster, Patent
Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-second day of April, in the
year of our Lord One thousand eight hundred and seventy-two, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Henry Bernoulli Barlow, Her special
licence that I, the said Henry Bernoulli Barlow, my executors, adminis-
trators, and assigns, or such others as I, the said Henry Bernoulli
Barlow, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might
make, use, exercise, and. vend, within the United Kingdom of Great

page_text: Britain and Ireland, the Channel Islands, and Isle of Man, an In-
vention for "IMPROVEMENTS IN APPARATUS FOR COOLING WORT AND OTHER
LIQUIs," being a communication to me from abroad by A. Naegeli, of
Wegeleben, in the Kingdom of Prussia, upon the condition (amongst
others) that I, the said Henry Bernoulli Barlow, my executors or
administrators, by an instrument in writing under my, or their, or
one of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was to
be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said Henry Bernoulli Barlow, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in' and
by the following statement (that is to say) :—
This improved apparatus consists of a cylindrical vessel containing any
suitable number of concentric compartments made of copper or other
metal. The liquid to be cooled flows down one set of compartments, and
the cold water ascends through the intervening compartments.
And in order that this Invention may be fully understood and readily
carried into operation, I will proceed to describe the accompanying Sheet
of Drawings, reference being had to the figures and letters marked
thercon.
Fig. 1 represents a vertical section of the improved apparatus; Fig. 2,
a plan; and Figs. 3 and 4 are cross sections through the lines A, B,
and C, D, on Fig. 1.
The apparatus consists principally of a cylindrical iron vessel, in the
interior of which there are any convenient number of copper cylinders
placed one within the other, and leaving spaces of about two inches and
five-eighths of an inch alternately. The narrow spaces are closed at top
and bottom, and jointed to each other above and below in opposite places
by means of the short tube joints 1, 2, 3, 4, 5, 6, and 7, as shewn in
Fig. 1, and partly also in Fig 4, and they are intended to hold the '
cooling water, whilst the wider spaces contain the wort or other liquid
to be cooled.
The wort or other liquid at the conclusion of the sugar forming
process is pumped through the tube a, in Fig. 1, into the cooling vessel;
i

page_text: the valve b is then closed, so that the iron cylinder and the two inch
spaces of the copper cylinders gradually fill with wort or other liquid,
while cold water is made to flow in at c filling the five-eighths of an inch
spaces to the top, and flowing off when warm by further pumping at d.
When the space for the wort in filled up to the line A, B, in Fig. 1, 6
and the pumping is still continued, the surplus wort or other liquid flows
out of the overflow tube e into the tube f (which is widened out into a
funnel shape to avoid the formation of a syphon), and thence into the
fermenting vats. This arrangement permits of a great cooling surface
in comparatively small space, and is the more effective because the 1
wort or other liquid to be cooled flows from above downwards, and the
cold water from below upwards, thus causing a counter current of great
cooling power, and with great economy of cooling water. When the
pumping in of hot wort at a has ceased the wort still remaining in
the cooler is drawn into the fermenting vats, not through the overflow e, 1
but by opening the valve b.
ˋ
For rinsing the vessel after it has been emptied water is let in through
the tube which is held by the iron bow 9, g; the lower end of the
tube / enters into the wider tube i. This tube i passes easily through
the lid k, k, of the vessel, and is inside the vessel divided into two 2
horizontal perforated arms, throwing out the rinsing water through
small orifices in opposite directions, as shewn in Fig. 1 and Fig. 3, thus
causing the rinsing tube to revolve and to cleanse all the surfaces of the
apparatus. In the centre there is a footstep, on which the rinsing tube
is poised to facilitate its rotary motion.
The bottom of the cooling vessel is made of cast iron, and it is provided
with feet like some other wort vessels.
This improved apparatus effects a great saving in the water required
for cooling, and economises space in the building.
Having thus stated the nature of the Invention communicated to me 3
by the within-named A. Naegeli, and described the manner of performing
the same, I wish it to be understood that I do not limit myself to the
details given, as they may be varied or modified, but what I claim is,—
First. The apparatus described containing concentric compartments
for the wort or other liquid to be cooled, and for the cold water or other

page_text: Secondly. Causing the wort or other liquid to be cooled to circulate
through the apparatus in the opposite direction to that of the cold water
or other cooling liquid, as described.
And, lastly. The revolving perforated radial tubes for distributing
water to rinse out and cleanse the cooling apparatus, as shewn and
described.
"
In witness whereof, I, the said Henry Bernoulli Barlow, have
hereto set my hand and seal, this Nineteenth day of October
One thousand eight hundred and seventy-two.
