Year: 1865

page_text: LETTERS PATENT to John Henry Johnson, of 47, Lincoln's Inn Fields,
in the County of Middlesex, Gentleman, for the Invention of "AN IM-
PROVED APPARATUS FOR FREEZING, ICEING, AND COOLING LIQUIDS."-A .com-
munication from abroad by Henry Nicholas Dallemagne, of Paris, in the
Empire of France, Merchant.
Sealed the 14th November 1865, and dated the 22nd May 1865.
PROVISIONAL SPECIFICATION left by the said John Henry Johnson at
the Office of the Commissioners of Patents, with his Petition, on the
22nd May 1865.
I, JOHN HENRY JOHNSON, of 47, Lincoln's Inn Fields, in the County of
Middlesex, Gentleman, do hereby declare the nature of the said Invention
for "AN IMPROVED APPARATUS FOR FREEZING, ICEING, AND COOLING LIQUIDS," a
communication to me from abroad by Henry Nicholas Dallemagne, of Paris,
in the Empire of France, Merchant, to be as follows:-
This Invention has reference to a simple and economical apparatus which
may be constructed in the form of a decanter or carafe for the purpose of
obtaining ice or for simply iceing or cooling liquids, and consists in the em-
ployment for such purpose of an outer and an inner vessel of glass or other
suitable material, each of which is provided with a separate mouth or orifice
of its own, the two vessels being so disposed that there shall be no com-
munication between their interiors. For this purpose the neck of the inner
vessel is brought through the side or other convenient part of the outer vessel,

page_text: and is provided with a stopper of its own, whilst the outer vessel is provided
with the usual or other neck suitable for decanters or water bottles if the
apparatus is required for use on the table; any shape or configuration may
however be given to the two vessels. The relative capacities of the liquid
spaces of the two vessels should be in the following proportions, namely, if the
capacity of the inner vessel be one quart, that of the surrounding space inside
the outer vessel should be about 0.750 of a quart. The inner vessel contains
the freezing or cooling mixture, and the outer one the liquid to be frozen,
iced, or cooled. Any well-known freezing mixture may be used, but it is
preferred to employ the following, namely:-
Sal ammoniac -
Nitrate of potash
Water
Or Nitrate of ammonia
Hydrated carbonate of soda

SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Henry Johnson in the Great Seal Patent Office on
the 22nd November 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
HENRY JOHNSON, of 47, Lincoln's Inn Fields, in the County of Middlesex,
Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of May, in the year of our Lord
One thousand eight hundred and sixty-five, in the 28th year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
John Henry Johnson, Her special license that I, the said John Henry
Johnson, my executors, administrators, and assigns, or such others as I, the said
John Henry Johnson, my executors, administrators, or 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 Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "AN IMPROVED APPARATUS
FOR FREEZING, ICEING, AND COOLING LIQUIDS," a communication to me from abroad
by Henry Nicholas Dallemagne, of Paris, in the Empire of France, Merchant,
upon the condition (amongst others) that I, the said John Henry Johnson, my

page_text: executors and administrators, by an instrument in writing under hand and seal,
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 John Henry Johnson, 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, reference being had to the accompanying Drawings, and
to the letters and figures marked thereon, that is to say :-
The said Invention has reference to a simple and economical apparatus
which may be constructed in the form of a decanter or carafe for the purpose
of obtaining ice, or for simply iceing or cooling liquids, and consists in the
employment for such purpose of an outer and an inner vessel of glass or other
suitable material, each of which is provided with a separate mouth or orifice
of its own, the two vessels being so disposed that there shall be no commu-
nication between their interiors. For this purpose the neck of the inner
vessel is brought through the side or other convenient part of the outer
vessel, and is provided with a stopper of its own, whilst the outer vessel is
provided with the usual or other neck suitable for decanters or water bottles
if the apparatus is required for use on the table; any shape or configuration
may however be given to the two vessels. The relative capacities of the
liquid spaces of the two vessels should be in the following proportions, namely,
if the capacity of the inner vessel be one quart, that of the surrounding space
inside the outer vessel should be about 0-750 of a quart. The inner vessel
contains the freezing or cooling mixture, and the outer one the liquid to be
frozen, iced, or cooled. Any well-known freezing mixture may be used, but
it is preferred to employ the following, namely:-
Sal ammoniac
-
Nitrate of potash
Water
Or Nitrate of ammonia
Hydrated carbonate of soda
Water
-
5 parts.

And in order that the said Invention may be fully understood I shall
refer to the annexed Drawing, which represents an elevation of a carafe
constructed according to this Invention.
A is the external vessel, and B the internal one, which is blown inside the
first. The liquid to be iced is introduced through the neck a, which is closed

page_text: by an ordinary stopper C whilst the freezing ingredients are introduced into
the vessel B through the mouth thereof, which passes through the side or
other convenient part of the outer vessel A, and is closed by a ground
stopper D. E is the handle of the complete apparatus. In some cases the
inner vessel may be connected to the outer one by screwing, so that when
used for iceing the two may be combined, but when no longer required for
that purpose they may be disconnected from each other.
Having now described and particularly ascertained the nature of the said
Invention, and the manner in which the same is or may be used or carried
into effect, I would observe in conclusion that what I consider to be novel
and original, and therefore claim as the Invention secured to me by the
herein-before in part recited Letters Patent is, the application and use to and
in the iceing or cooling of liquids of a carafe, decanter, or other form of vessel
containing within it a second vessel for holding the freezing mixture, there
being no communication between the interiors of the two vessels, substantially
as herein-before described, and illustrated by the Drawing.
In witness whereof, I, the said John Henry Johnson, have hereunto set
my hand and seal, the Twenty-second day of November, One thou-
sand eight hundred and sixty-five.
J. HENRY JOHNSON. (L.S.)
