Year: 1869

page_text: LETTERS PATENT to John Askew, of No. 27; Charles Street,
Hampstead Road, in the County of Middlesex, Coppersmith, for
the Invention of "AN, IMPROVED REFRIGERATOR FOR COOLING BREWERS'
AND DISTILLERS' WORT."
Sealed the 31st May 1870, and dated the 15th December 1869..
PROVISIONAL SPECIFICATION left by the said John Askew at the
Office of the Commissioners of Patents, with his Petition, on the
15th December 1869.
I, JOHN ASKEW, of No. 27, Charles Street, Hampstead Road, in the
County of Middlesex, Coppersmith, do hereby declare the nature of
the said Invention for "AN IMPROVED REFRIGERATOR POR COOLING BREWERS'
AND DISTILLERS' WORT," to be as follows:-
This Invention has for its object an improvement in refrigerators for
brewers, distillers, and others..
The refrigerator consists of the following parts for their various
purposes: A series of flat, oval, or globular metal receivers, I prefer
them watch shaped, screwed or fastened one on top of the other forming

page_text: a vertical pile, in number varying according to the quantity of wort or
other liquids to be cooled or the amount of work as to time or quantity
to be done by the refrigerator. On the top of the pile or series is
screwed or fastened a perforated receiver. The wort or other liquid to be
cooled being conveyed by a pipe or pipes to this perforated receiver
passes through the perforations, and spreading itself into a thin sheet
covers the upper and under surfaces of the first or topmost globular
receiver; thence it passes to the second, which it covers in like manner,
and so on downwards over the pile until it reaches the last one, from
which it similarly passes into a pan or receptacle at the bottom, in which
the pile stands, and from this pan or receptacle into the working rounds
or squares. The interiors of the several globular receivers are in free open
communication. Cold water being forced into the bottom receiver, which
it fills, passes into the next, and so by rising and thus passing in contrary
direction to the course of the descending wort or other liquid fills and
continues to flow upwards through the pile; the water may the pass
through a pipe or pipes into the liquid back or waste main or elsewhere
ás may be desired.
Taps or other regulators of the respective currents of hot liquor and
Luxerint nacitiona
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Askew in the Great Seal Patent Office on
the 7th June 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
ASKEW, of No. 27, Charles Street, Hampstead Road, in the County of
Middlesex, Coppersmith, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifteenth day of December, in the
year of our Lord One thousand eight hundred and sixty-nine, in the
thirty-third year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said John Askew, Her special
licence that I, the said John Askew, my executors, administrators, and
assigns, or such others as I, the said John Askew, my executors, admi-
nistrators, and assigns, should at any time agree with, and no others,
from time to time and at all times thereafter during the term therein

page_text: expressed, should and lawfully might make, use, exercise, and vend,
within the United Kingdom of Great Britain and Ireland, tho Channel
Islands, and Isle of Man, an Invention for "AN IMPROVED REFRIGERATOR
FOR COOLING BREWERS' AND DISTILLERS' WORT," upon the condition (amongst
others) that I, the said John Askew, 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 John Askew, 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 an improvement in refrigerators for
brewers, distillers, and others.
The refrigerator (as shewn in annexed Drawing) consists of the
following parts for their various purposes:-A series of flat, oval, or
globular (I prefer them watch shaped) metal receivers (marked F in
Drawing) screwed or fastened one on top of the other forming a vertical
pile, in number varying according to the quantity of wort or other liquid
to be cooled or the amount of work as to time or quantity to be done by
the refrigerator. On the top of the pile or series is screwed or fastened
a perforated receiver (as shewn and marked C in Drawing). The wort
or other liquid to be cooled being conveyed by a pipe or pipes to this
perforated receiver passes through the perforations, and spreading itself
into a thin sheet covers the upper and under surfaces of the first or
topmost globular receiver; thence it passes to the second, which it
covers in like manner, and so on downwards over the pile until it
reaches the last one, from which it similarly passes into a cooler at the
bottom (marked E), in which cooler the pile stands, and from this into
the working rounds or squares. Passing from top to bottom of the pile
through the watch-shaped globular receivers and serving as support to
them is a vertical pipe (marked G) with perforations top and bottom, as
marked, firmly screwed in its position. A blank a short distance from
the upper end prevents the upward escape of the contained air, which
pressing upon the surface of the water which enters at A causes it to

page_text: flow constantly and regularly upwards through the pile; arrived at the
top the water passes again into the tube by the perforations above the
blank and away by B. The interior of the several globular receivers,
which are strengthened if necessary top and bottom by L plates or other
angle pieces, as shewn in the Drawing, are in free open communication.
Cold water being forced into the bottom receiver (through A) fills it,
passes into the next, and so by rising and thus passing in contrary
direction to the course of the descending wort or other liquid fills and
continues to flow upwards through the pile; the water may then pass
through a pipe (B) or pipes into the liquor back or waste main or
elsewhere, as may be desired. The circulation of the water in the
receivers is insured by the presence of the metal discs (marked H, H).
Taps or other regulators of the respective currents of hot liquor and
cold water are placed in convenient positions.
The above is a description of the nature of my improvement for
cooling worts and other liquids. I do not however limit myself to the
precise details of form and material; but what I claim particularly is,
the constructive arrangement of the globular receivers by which I obtain
increased surface and other advantages.
In witness whereof, I, the said John Askew, have hereunto set
my hand and seal, this Seventh day of June, in the year of
our Lord 1870.
Witness,
EDWARD T. ELIOT.
JOHN ASKEW. (L.S.)
