AN IMPROVEMENT IN THE MANUFACTURE OF BEER
Year: 1872

page_text: LETTERS PATENT to Francis Coales, of Chicheley, near Newport
Pagnell, in the County of Bucks, Farmer, for the Invention of
"AN IMPROVEMENT IN THE MANUFACTURE OF BEER."
Sealed the 28th June 1872, and dated the 5th April 1872.
PROVISIONAL SPECIFICATION left by the said Francis Coales at the
Office of the Commissioners of Patents, with his Petition, on the
5th April 1872.
I, FRANCIS COALES, of Chicheley, near Newport Pagnell, in the
County of Bucks, Farmer, do hereby declare the nature of the said
Invention for "AN IMPROVEMENT IN THE MANUFACTURE OF BEER," to be as
follows:-
This Invention relates to an improvement in the brewing of beer, the
object being to effect an economy in the manufacture. In order to
attain this end without detracting from the quality of beer I employ
mangel wurzel or beet root in partial substitution of malt in the pre-

page_text: paration of the sweet wort. The mangel or beet having been first
washed is reduced to pulp in a pulping machine and placed in a mash
tub, hot water is then run into the tub and the hot solution thus
obtained is transferred to a copper where it is boiled together with the
malt preparation of the sweet wort. By this mode of treating the
mangel or beet I obtain a sweet extract free from all acrid taste and
admirably suited for use in the preparation of sweet wort. The pulp
after being washed may be used as food for cattle.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Francis Coales in the Great Seal Patent Office
on the 4th October 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FRANCIS
COALES, of Chicheley, near Newport Pagnell, in the County of Bucks,
Farmer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Fifth day of April, in the year of,
our Lord One thousand eight hundred and seventy-two, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Francis Coales, Her special licence
that I, the said Francis Coales, my executors, administrators, and
assigns, or such others as I, the said Francis Coales, 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 "AN IMPROVEMENT
IN THE MANUFACTURE OF BEER," upon the condition (amongst others) that
I, the said Francis Coales, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Inven-
tion, 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.

page_text: NOW KNOW YE, that I, the said Francis Coales, 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, that is to say: :-
This Invention relates to an improvement in the brewing of beer, the
object being to effect an economy in the manufacture. In order to
attain this end without detracting from the quality of the beer I employ
mangel wurzel or beet root (which are cheap materials) in partial
substitution of malt (which is a far more expensive material) in the
preparation of the sweet wort. I have found that when beet root or
mangel wurzel is boiled to obtain a sweet solution therefrom it will
yield a wort that is wholly unsuited to the brewer owing to its acrid
properties. I have however proved by experiment that by a proper
treatment of these materials a satisfactory result may be secured, and
a great economy in brewing thereby obtained. To this end I first wash
the mangel wurzel or beet root and then reduce the same to pulp by
the aid of a pulping machine of any approved construction. The pulp
thus obtained I place in a mash tub and then run boiling water therein,
and leave it to stand for say five minutes more or less. The hot
solution thus obtained I transfer to a copper and boil it to restore the
temperature lost by the water in the mash tub. I next run the hot
solution into a mash tun containing the dry malt which is intended to
be used in completing the preparation of the sweet wort.
The proportions of the materials which I have employed with a
good result in making a hogshead of wort are beet root or mangel
wurzel five bushels, malt two and a half bushels. The malt in the mash
tun I treat in the ordinary way practised by brewers, and the sweet wort
thereby obtained I use as heretofore, boiling it with hops in any desired
proportions.
By the above described mode of treating the mangel or beet I obtain
a sweet extract free from all acrid taste and admirably suited for use in
the preparation of sweet wort. The pulp after being washed may be
used as food for cattle.
Having now set forth the nature of my Invention of "An Improve-
ment in the Manufacture of Beer," and explained the manner of
