within that part of His Kingdom of Great Britain called England, His
Dominion of Wales, and Town of Berwick-upon-Tweed, and also in His
Colonies and Plantations abroad, my Invention of "AN ENTIRE NEW AND
PARTICULAR KIND OF METHOD OF REDUCING MALT AND HOPS INTO A SOLID ESSENCE
OR EXTRACT FOR THE PURPOSE OF MAKING GOOD AND WHOLESOME BEERS AT SEA AND
IN DISTANT CLIMES AND COUNTRIES," in such manner as to me, the said Robert
Thornton, my executors, admors, or assigns, or any of them, should in their
discretions seem meet, and that I, the said Robert Thornton, my executors,
admors, and assigns, should and lawfully might have and enjoy the whole

page_text: profit, benefit, commodity, and advantage from time to time coming, growing,
and arising by reason of the said Invention, for and- during the term of years
therein mentioned, to have, hold, exercise, and enjoy the said licence, powers,
priviledges, and advantages therein-before granted or mentioned to be granted
unto me, the said Robert Thornton, my executors, adñors, and assigns, for
and during and unto the full end and term of fourteen years from the date
of the said Letters Patent next and immediately ensuing, and fully to be com-
pleat and ended, according to the Statute in such case made and provided;
in which said recited Letters Patent there is contained a provisoe obliging
me, the said Robert Thornton, by an instrument in writing under my hand
and seal, to cause a particular description of the nature of my said Invention,
and in what manner the same is to be performed, to be inrolled in His
Majesty's High Court of Chancery within four calender months next and
immediately after the date of the said recited Letters Patent, as in and by the
same (relation being thereunto had) may more fully and at large appear.
NOW KNOW YE, that in compliance with the said provisoe, I, the said
Robert Thornton, do hereby declare that my. said Invention. of An Intire
New and Particular Kind of Method of Reducing Malt and Hops into a
Solid Essence or Extract for the Purpose of Making Good and Wholesome
Beers at Sea and in distant Climes and Countries, is performed and described
in the manner following (that is to say):-
The new method of preparing an essence or extract of malt and hops is by
the transmitted heat of compressed vapour of boiling water, and a proper
apparatus for, that purpose. This apparatus may be made of iron, tin, or
copper; it consists of a boiler of any dimensions, a double vessell, and con-
ducting tubes. The double vessell consists of one vessel placed within
another and fitted tight at their rims. The upper vessel forms. the upper
part of the under vessel, and contains the liquor to be evaporated. The under
vessel is everywhere inclosed but at an aperture communicating with a boiler,
and at another aperture communicating with the conducting tubes; is.con-
structed so as not to allow any part of. the vapor condensed into drops within
it to escape, but back again into the boiler; is not so extensive as to act as a
common refrigatory, and yet capacious enough to prevent the liquor boiling
over. The aperture communicating with the boiler is large enough to freely
admit the vapor from the boiler into the under, vessel, and the aperture
communicating with the conducting, tubes is of a proper size to allow of the
vapor in the.under vessel being compressed to a degree capable of transmit-
ting to the liquor to. be evaporated to a proper heat, and at the same time. to
serve as a passage for more heat than is necessary to keep up that degree of

page_text: compression. The conducting tubes are to convey this superfluous heat or
vapor to be used for further purposes, or immediately out of the building.
In witness whereof, I, the said Robert Thornton, have hereunto set
my hand and seal, this Third day of August, in the eighteenth year of
the reign of our Sovereign Lord George the Third, by the grace of
God of Great Britain, France, and Ireland King, Defender of the
Faith, and so forth, and in the year of our Lord One thousand seven
hundred and seventy-eight.
