IMPROVEMENTS IN BREWING
Year: 1841

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JONATHAN
BEILBY, of York, Brewer, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria by Her
Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Fifth day of April, in the fourth year of Her reign, did, for
Herself, Her heirs, and successors, give and grant unto me, the said Jonathan
Beilby, Her especial licence, that I, the said Jonathan Beilby, my exors,
adñiors, and assigns, or such others as I, the said Jonathan Beilby, my exors,
admiors, or assigns, should at any time agree with, and no others from time
to time, and at all times during the term of years therein expressed, should
and lawfully might make, use, exercise, and vend, within England, Wales,
and the Town of Berwick-upon-Tweed, my Invention of "IMPROVEMENTS IN
BREWING;" in which said Letters Patent is contained a proviso, obliging me,
the said Jonathan , by an instrument in writing, under my hand and
seal, particularly to describe and ascertain the nature of my said Invention;
and in what manner the same is to be performed, and to cause the same to be
inrolled in Her said Majesty's High Court of Chancery within six calendar
months next and immediately after the date of the said in part recited Letters
Patent, as in and by the same, reference being thereunto had, will more
fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I; the said
Jonathan Beilby, do hereby declare the nature of my said Invention to consist:
First, in boiling the worts when they leave the mash tun with the hops in

page_text: a close boiler, under such high pressure as shall cause them rapidly to attain
from two hundred and fifty to two hundred and sixty degrees of temperature.
And secondly, in then cooling them down rapidly, by means of a refrigerating
apparatus, to a proper degree of temperature to be received into the ordinary
coolers, whereby I effect a great saving in fuel and time, inasmuch as I thus
obtain all the extract that is gained by a longer process of boiling in open
boilers, or at a less temperature, while the worts are equally as soon ready,
(owing to the refrigerating apparatus,) to be received into the ordinary coolers;
and in further compliance with the said proviso, I, the said Jonathan Beilby,
do hereby describe the manner in which my said Invention is to be performed,
by the following statement thereof, reference being had to the Drawing annexed,
and to the figures and letters marked thereon, (that is to say) :-
DESCRIPTION OF THE DRAWING.
:―
Figure 1 represents a high pressure boiler; A, A, is the boiler which is set
in brick-work; B, B, and C, is the furnace; D, the flues; and E the ash-pit;
F is a man hole or cover, which is kept tight by the screw G; H is a tube,
fixed to the boiler, and containing mercury; into this tube is placed the
thermometer or heat guage; I, provided with a graduated scale as usual; J is
a vent cock for the steam; and K is a properly weighted safety valve.
The upper portion of the boiler is partly surrounded with a casing or
jacket L, L, to contain cold water; M is a waste or overflow pipe, attached to
the casing; and N is a syphon, to draw out the water from the casing when it
is required to change or empty it; O is the cock by which the worts are
drawn out of the boiler; P is a water tank, placed at any convenient distance
from the boiler; and Q is a pipe provided with a stop cock, which conveys the
water from the tank P into the casing L, as occasion may require; R is also
a pipe which supplies the boiler with water if required; this pipe is also
provided with a stop cock S.
Having now described my arrangement of high pressure boiler, with its
refrigerating apparatus, I will proceed to describe the manner in which I
effect my said improvements in brewing by means thereof:-The ground malt
and liquor having been put into the mash tun, and the process of mashing
having been performed in the usual manner, I pump or run, as the case may
be (dependent on the position of the boiler with reference to the mash tun),
the worts into the boiler, and add the hops in the usual way; I then get up
the heat in the boiler as fast as possible, under the necessary pressure, to from
two hundred and fifty to two hundred and sixty degrees of Fahrenheit, which I
can accomplish generally in about a quarter of an hour after the boiling point

page_text: is attained. I then instantly draw the fire from under the boiler, and let the
cold water from the tank P into the refrigerating jacket L, L, which surrounds
the boiler, and in about another quarter of an hour the worts are thus reduced
to a temperature sufficiently low to admit of their being received into the
ordinary coolers.
And whereas I claim as my Invention, first, the rapidly heating to a high
temperature, (say from about two hundred and fifty to two hundred and sixty
degrees,) and under a suitable high pressure, the worts when taken from the
mash tun and placed with the hops in the copper, to be boiled; and then,
secondly, as soon as they have reached that temperature, rapidly cooling them
down to the usual and proper temperature, to be received into the ordinary
coolers, whereby a great saving of fuel and of time is effected, and an equally
perfect extract obtained as by the usual slow boiling process in open boilers,
or under very low pressure. And such my Invention being, to the best of
my knowledge and belief, entirely new and never before used within that part
of Her said Majesty's United Kingdom of Great Britain and Ireland called
England, Her said dominion of Wales, or Town of Berwick-upon-Tweed, I do
hereby declare this to be my Specification of the same, and that I do verily
believe this, my said Specification, doth comply in all respects fully and without
reserve or disguise with the proviso, in the said herein-before in part recited
Letters Patent contained, wherefore I hereby claim to maintain exclusive right
and privilege to my said Invention.
In witness whereof, I, the said Jonathan Beilby, have hereunto set my
hand and seal, this Thirtieth day of September, in the year of our
Lord One thousand eight hundred and forty-one.
