page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
ROBERTS, of Macclesfield, in the County of Chester, Cotton Spinner, send
greeting.
WHEREAS His most Excellent Majesty King George the Third did, by
His Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Twentieth day of
February, in the fifty-third year of His reign, give and grant unto me, the
said John Roberts, my exors, adñors, and assigns, His especial licence, full
power, sole priviledge and authority, that I, the said John Roberts, my exors,
admors, and assigns, and every of them, by myself, and themselves, or by
my and their deputy or deputies, servants or agents, or such others as I, the
said John Roberts, my exors, admors, or assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during the
term of years therein expressed, should and lawfully might make, use, exercise,
and vend, within that part of the United Kingdom of Great Britain and Ireland
called England, the Dominion of Wales, and Town of Berwick-upon-Tweed,
my Invention of "A METHOD OF CONCENTRATING OR REDUCING INTO SMALL COM-
PASS SUCH PARTS OF MALT AND HOPS AS ARE REQUISITE IN MAKING ALE, BEER,
AND PORTER;" in which Letters Patent there is contained a provise obliging
me, the said John Roberts, particularly to describe and ascertain the nature
of my said Invention, and in what manner the same is to be performed, by

page_text: an instrument in writing under my hand and seal, and to cause the same to
be inrolled in His Majesty's High Court of Chancery within two calendar
months next and immediately after the date of the said Letters Patent, as in
and by the said Letters Patent, relation being thereunto had, may more fully
and at large appear.
NOW KNOW YE, that in pursuance of and in compliance with the said
recited proviso, I, the said John Roberts, do hereby declare that the nature
of my said Invention, and the manner in which the same is to be performed,
is as herein-after mentioned :-
My Method of Concentrating or Reducing into Small Compass such Parts of
Malt and Hops as are Requisite in making Ale, Beer, and Porter, consists
in evaporating a considerable portion of the water contained in the wort or
liquor produced from malt in the ordinary process of brewing after the hops
have been boiled, digested, or infused therein, or in some part thereof, or after
an infusion or decoction of hops has been mixed therewith, until the residue
is reduced to, or nearly to, the consistence of thin molasses, or to a state of
solidity equal to that of the extract of liquorice, cominonly called Spanish
liquorice, or any intermediate state of consistence, and which evaporation is
performed by heating the liquor, and maintaining it at any degree, or different
degrees, of heat which will support the evaporation, not exceeding the boiling
point.
And my method of concentrating or reducing into small compass such
parts of malt only as are requisite in making ale, beer, and porter, consists
in evaporating a considerable portion of the water contained in the wort or
liquor produced from malt in the ordinary process of brewing before any
hops have been boiled, digested, or infused therein, and before any infusion or
decoction of hops has been mixed therewith, until the residue is reduced to
any such a state of consistence as is herein-before described, by such means of
evaporation as are herein-before mentioned. The said concentrated substances,
produced in the manner before mentioned, may be preserved for a considerable
length of time, if liquid, in close-stopt barrels or bottles, or if solid, by keeping
the same dry, and may be used as convenience may require.
The method of using the said concentrated substances is, by dissolving them
in as much hot water as may be requisite for producing ale, beer, or porter,
of the desired strength, and afterwards treating the solution in the same
manner as the liquor from which the concentrated substances have been produced
would have been treated in the ordinary process of brewing. The concen-
trated substances may be considered as producing the like, or very nearly the
like, quantity of ale, beer, or porter, and of the like, or very nearly the like,

page_text: strength as would have been produced from the liquor from which such con-
centrated substances have been formed.
In witness whereof, I, the said John Roberts, have hereunto set my
hand and seal, the Fifth day of March, in the year of our Lord One
thousand eight hundred and thirteen.
AND BE IT REMEMBERED, that on the Fifth day of March, in the
year of our Lord 1813, the aforesaid John Roberts came before our said
Lord the King in His Chancery, and acknowleged the Specification afore-
said, and all and every thing therein contained and specified, in form above
written. And also the Specification aforesaid was stampt according to the
tenor of the Statute made for that purpose.
Inrolled the Eighth day of March, in the year of our Lord One thousand
eight hundred and thirteen.
