Year: 1870

page_text: LETTERS PATENT to William Edwin Heath, of 23, Camden Road, in
the County of Middlesex, Engineer, for the Invention of "IMPROVE-
MENTS IN COOLING OR REFRIGERATING BEER, LIQUORS, OR BEVERAGES, AND
APPARATUS THEREFOR.'
"
PROVISIONAL SPECIFICATION left by the said William Edwin Heath
at the Office of the Commissioners of Patents, with his Petition, on
the 23rd May 1870.
I, WILLIAM EDWIN HEATH, of 23, Camden Road, in the County of
Middlesex, Engineer, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN COOLING OR REFRIGERATING BEER, LIQUORS, OR
BEVERAGES, AND APPARATUS THEREFOR," to be as follows:-
This Invention has for its object the cooling or refrigerating beer or
other beverages on draught.
I prepare a chamber of any convenient form, by preference rect-
angular, with a lid at top capable of being opened or closed. I cover or
line the inside of this chamber with felt, hair, or any other suitable

page_text: material as a non-conductor of heat, or I form double sides or air
chambers for the same purpose, namely, to prevent the conduction of
heat from or to the interior of the chamber. I finish the inside of
the chamber with a lining over all of metal or any other suitable
material to contain water or other liquids. I make one or more spiral or
other shaped tubes of circular, or rectangular, or any other section, and
arrange or group them or it in the interior of the chamber so that their
two extremities will come through the outside of the chamber in any con-
venient place, but by preference through the sides at the top and bottom,
the places of penetration being made water-tight by unions, and screws;
and washes. I connect one of the extremities of each spiral or other
formed pipe with the pipe proceeding from the cask or cistern, or other
source of the liquid to be cooled on the outside of the chamber aforesaid,
and I connect the other extremity of the spiral, &c., with the tap or
other outlet for the liquid both on the outside of the chamber or other-
wise. I fill this chamber in the spaces between the coils of pipes with
icc or liquid at a low temperature or with acids or other liquids capable
of freezing or reducing the température. As soon as the tap is turned
on or the engine pull put in action the liquid to be cooled passes
through the coil in the cooling chamber, and coming into contact with
the inner side of the pipe or form of refrigerator, the outside of which is
at the same time in contact with the ice or other cooling medium, the
liquid intended to be cooled immediately looses a great portion of its
heat and flows at the tap or lip of the engine at a much lower
temperature than it otherwise would. This apparatus is intended to be
fixed at any point between the source of supply of the liquid and the
outlet, but in the case of beer engines by preference between the
pump of the engine and the lip. I form a waste or overflow pipe to
convey away any excess of liquid, and I support the whole on brackets
or otherwise sustain it.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Edwin. Heath in the Great. Seal Patent
Office on the 23rd November 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME; WILLIAM
EDWIN HEATH, of 23, Camden Road, in the County of Middlesex, 35
Engineer, send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-third day of May, in the year
of our Lord One thousand eight hundred and seventy, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Edwin Heath, Her special
licence that I, the said William Edwin Heath, my executors, adminis-
trators, and assigns, or such others as. I, the said William Edwin
Heath, my executors, 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
"IMPROVEMENTS IN COOLING OR REFRIGERATING BEER, LIQUORS, OR BEVERAGES,
AND APPARATUS THEREFOR," upon the condition (amongst others) that I,
the said William Edwin Heath, 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 William Edwin Heath, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement:-
This Invention has for its object the cooling or refrigerating water,
beer, or beverages on draught, or decanting or cooling wines, &c.
:
I prepare a chamber of any convenient form with a lid at top or
I cover or
any convenient part capable of being opened or closed.
line the inside of this chamber with felt, hair, or any other suitable
material as a non-conductor of heat, or I form double sides or air
chambers for the same purpose, namely, to prevent the conduction
of heat from or to the interior of the chamber. I finish the inside
of the chamber with a lining over all of metal or any other suitable
material to contain ice water or other liquids. I make one or more
spiral or other shaped tubes of circular or rectangular or any other
form or shape of section, and arrange or group them or it in the

page_text: interior of the chamber so that their two extremities will come through
the outside of the chamber or in any convenient position, but, by
preference, through the sides at the top and bottom. The places of pene-
tration being made water-tight by unions, screws, and washers, I con-
nect one of the extremities of each spiral or other formed pipe with the
pipe proceeding from the cask or cistern or other source of the liquid to
be cooled or (in cooling wines from the bottle with a small funnel and
strainer combined for convenience of decanting) on the outside of the
chamber aforesaid, and I connect the other extremity of the spiral, &c.
with the tap or other outlet for the liquid; or in cooling wines from the
bottle the lower extremity of the coil is connected with a funnel point
for inserting into the decanter, both on the outside of the chamber or
otherwise. I fill this chamber in the spaces between the coils of pipes
with ice or liquid at a low temperature, or with acids or other liquids
capable of freezing or reducing the temperature of anything they may
be brought into contact with. As soon as the tap is turned on or the
engine pull up in action, or the liquor, &c. to be cooled is caused in
any way to pass through the inside of the coil, either by its own gravity
or by any mechanical action or force, it being in contact with the inner
side of the pipe or other form of refrigerator, the outside of which is at
the same time in contact with the ice or other cooling medium, the liquid
intended to be cooled immediately looses a great portion of its heat by
conduction, and flows at the tap or lip of the engine or spout of the
funnel or other place of delivery at a much lower temperature than it
otherwise would. The apparatus is intended to be fixed or used at any
point between the source of supply of the liquid and the outlet; but in
the case of beer engines, by preference, between the pump of the engine
and the lip, and in casks or filters between the cask or other source and
the tap. I form a waste or overflow pipe to convey away any excessive
liquid where necessary, and I support the whole on brackets or otherwise
to sustain it or not, as circumstances require.
I wish it to be understood that I do not claim as new either the ice
safe or non-conducting chamber separately; nor do I claim as a new
Invention the use of a coil or spiral of pipe; but what I claim is, the
combination for the purposes herein-before set forth of coil of a metal or
other pipe with a non-conducting chamber, as before described, for the
purpose (among others) of economizing and preventing waste of cooling

page_text: power by excluding as much as possible the action of the outside
temperature on either the coil or the freezing compound or the ice.
In witness wheroof, I, the said William Edwin Heath, have here-
unto set my hand and seal, this Twenty-third day of November,
One thousand eight hundred and seventy.
W. E. HEATH. (L.S.)
