IMPROVEMENTS IN APPARATUS FOR COOLING OR REFRIGERATING LIQUIDS
Year: 1870

page_text: :
LETTERS PATENT to Adolphus Frankenberg, of Manchester, in the
County of Lancaster, for the Invention of "IMPROVEMENTS IN
APPARATUS FOR COOLING OR REFRIGERATING LIQUIDS."
Sealed the 4th April 1871, and dated the 8th October 1870.
PROVISIONAL SPECIFICATION left by the said Adolphus Frankenberg
at the Office of the Commissioners of Patents, with his Petition,
on the 8th October 1870.
I, ADOLPHUS FRANKENBERG, of Manchester, in the County of
Lancaster, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN APPARATUS FOR COOLING OR REFRIGERATING LIQUIDS," to be
as follows: -
This Invention is designed for cooling or refrigerating liquids whilst
passing from a barrel or vessel to the tap where the liquid is drawn off,
or whilst passing from one vessel to another.
It is specially applicable to an improved apparatus for raising and
drawing off liquids for which I have filed a petition for Letters Patent,

page_text: No. 2522, dated September 20th, A.D. 1870, but it may also be used with
advantage in connection with any ordinary drawing-off apparatus, and
also by brewers, distillers, and others where it is desirable to cool a liquid
passing through a pipe from a vessel to a tap, or from one vessel to
another.
In any convenient situation between the vessel and the tap (or between
the two vessels) I place an air-tight block tin or other metal receptacle,
through which passes a serpentine or coiled pipe. Through this pipe
passes a number (say ten, twenty, or other required number) of smaller
block tin pipes, according to the number of barrels or other vessels from
which the liquor has to be drawn, the said pipes being connected at one
end to the barrels or vessels, and at the other to the respective taps.
This vessel or receptacle being filled with ice it will be found that owing
to its being closed air-tight the ice will not melt but will serve to cool
the liquid passing through it in the pipes for several weeks or even
months without re-charging. If a mixture of snow and saltpetre be
placed in this vessel in the winter or early spring, and the lid be then
fastened down air-tight, and the mixture be agitated in the presence of
moderate heat by means of a fan or agitator provided for that purpose, it
will form a solid block of ice completely filling the vessel, and it will
remain cold for several months, and will cool or refrigerate any liquid
passing through the pipes inside the coil.
¡
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Adolphus Frankenberg in the Great Seal Patent
Office on the 8th April 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ADOLPHUS
FRANKENBERG, of Manchester, in the County of Lancaster, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighth day of October, in the
year of our Lord One thousand eight hundred and seventy, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Adolphus Frankenberg, Her special license

page_text: that I, the said Adolphus Frankenberg, my executors, administrators,
and assigns, or such. others. as. I, the said Adolphus Frankenberg, my
exccutors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise,
and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVE-
MENTS IN APPARATUS FOR COOLING OR REFRIGERATING LIQUIDS," upon the con-
dition (amongst others) that I, the said Adolphus Frankenberg, my
executors or administrators, by an instrument in writing under my, or
their, or one of their hands and scals, 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 Adolphus Frankenberg; 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 and accompanying Drawings (that
is to say): :-
This Invention is designed for cooling or refrigerating liquids whilst
passing from a barrel or vessel to the tap where the liquid is drawn off,
or whilst passing from one vessel to another, and may be used with
advantage in connection with any ordinary drawing-off apparatus, and
also by brewers, distillers, and others where it is desirable to cool a liquid
passing through a pipe from a vessel to a tap, or from one vessel to
another.
In any convenient situation between the vessel and the tap (or between
the two vessels) I place an air-tight block tin or other metal receptacle,
through which passes a serpentine or coiled pipe. This pipe encloses a
number (say ten, twenty, or other required number) of smaller block tin.
pipes according to the number of barrels or other vessels from which the
liquor has to be drawn, the said pipes being connected at one end to the
barrels or, and at the other to the respective taps. This vessel or
receptacle being filled with ice it will be found that owing to its being
closed air-tight the ice will not melt but will serve to cool the liquid
passing through it in the pipes for several weeks or even months without

page_text: re-charging. If a mixture of snow and saltpetre be placed in this vessel
in the winter or early spring, and the lid be then fastened down air-tight,
and the mixture be agitated in the presence of moderate heat by means
of a fan or agitator provided for that purpose, it will form a solid block
of ice completely filling the vessel, and remain cold for several months,
and will cool or refrigerate any liquid passing through the pipes inside
the coil.
-
Such being the nature and object of my said Invention for " Improve-
ments in Apparatus for Cooling or Refrigerating Liquids," I will now
proceed to describe more in detail the manner in which the same is to
be or may be performed or carried into practical effect, and in order
that the same may be clearly understood I have annexed hereunto a
Sheet of Drawings illustrative thereof, and have marked the same with
figures and letters of reference corresponding with those in the following
explanation thereof.
Fig. 1 in the annexed Drawing is an elevation (shown partly in
section) of my improved apparatus, and Fig. 2 is a plan view or horizontal
section of the same.
a, a, is the air-tight vessel or receptacle for the ice made of block tin
or other suitable metal, and enclosing a serpentine or coiled pipe b, b,
(also of block tin) through which passes a number of smaller pipes c, c,
of a similar material. The upper ends of these pipes are connected with
the barrels or vessels containing the liquids to be drawn off, and their
lower ends are connected to their respective taps. In order to prevent
mistakes I mark both ends of each pipe with a similar number or letter
so as to avoid confusion in connecting the said pipes to their respective
vessels and taps. d, d, is an air-tight cover to the vessel.
When broken ice is used this is all that is requisite, but when a mixture
of snow and saltpetre is employed it is necessary to have a fan, as shown
in dotted lines in Fig. 1, for the purpose of agitating the mixture to
promote the freezing.
Having now described the nature and object of my said Invention,
together with the manner in which the same is to be or may be performed
or. carried into practical effect, I wish it to be understood that I claim
as my Invention, the apparatus for cooling or refrigerating liquids as
herein-before described and illustrated by the Drawing annexed; and
more especially I claim the use of the air-tight vessel in combination

page_text: with a serpentine or coiled pipe enclosing a number of smaller tubes,
substantially as shown and described.
In witness whereof, I, the said Adolphus Frankenberg, have hereunto
set my hand and seal, this Sixth day of April, in the year of our
Lord One thousand eight hundred and seventy-one.
