A NEW METHOD OF TUNNING AND CLEANSING ALES AND BEERS INTO CASKS
Year: 1810

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
GRIGORY, of Islington, in the County of Middlesex, Builder, 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 Twenty-second day of
March, in the fiftieth year of His reign, give and grant unto me, the said John
Grigory, my exors, admors, and assigns, his especial licence, full power, sole
privilege and authority that I, the said John Grigory, my exors, admors,
and assigns, during the term of years therein mentioned, should and lawfully
might make, use, exercise, and vend, within England, Wales, and the Town
of Berwick-upon-Tweed, my Invention of "A NEW METHOD OF TUNNING AND
CLEANSING ALES AND BEERS INTO CASKS;" in which said Letters Patent there is
contained a proviso, obliging me, the said John Grigory, 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 two calendar
months 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 proviso, I, the said
John Grigory, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, are particularly described
and ascertained as follows, that is to say :-

page_text: In the Drawings, Fig. 1 and Fig. 2, hereunto annexed, the letters A, B,
C, D, denote the square, or round, or cleansing batch or other vessel in which
beer, ale, or worts is supposed to be in readiness for tunning after having
passed through the first stages of its fermentation; E, E, is a pipe through
which the fermented liquor is conveyed by a main pipe F, F, and branches
G, G, into any number of butts, barrels, or other vessels P, Q, R, (which act
of drawing off or conveying is called tunning or cleansing); S, S, is a vessel
into which part of the fermenting liquor from the before-described vessel
A, B, C, D, is admitted through L, and serves to support a float K, K, which
rises and falls with the liquor, and by means of the arm branch or beam
M, M, M, which is properly supported, raises and lowers a sluice or sliding
piece N, to the effect, that when the float K, K, is considerably raised the
sliding piece N shall shut off the communication through E; and contrarywise,
when the float K, K, is suffered to subside, the sliding piece N shall afford less
obstruction, or leave the passage through E quite open; and I do farther
declare that the said passage through E may be opened, shut, or obstructed by
the action of a float in S, S, operating upon a cock in the manner of what is
called the ball cock, and that a like effect may be produced by various other
well-known contrivances. The buts, barrels, or vessels P, Q, R, aforesaid are
so placed that the respective bung-holes H, H, H, shall lie in the same level or
horizontal plane, or nearly so, as the surface T, T, at which the liquor in the
vessel S, S, will stand immediately previous to or at the time when the float
K, K, shall by its ascent compleatly shut the opening through E, and the object
or consequence of such disposition or placing is that the liquor from the before-
described vessel A, B, C, D, will flow through the pipes E, F, into the buts,
barrels, or other vessels P, Q, R, so as compleatly to fill them, and no more,
and will prevent any yeast from lodging in the upper part of the said buts,
barrels, or other vessels. And I do farther declare that my said Invention or
method produces the advantage of a very considerable saving of labor in tun-
ning or cleansing ales or beers as aforesaid, and is calculated to produce a much
clearer, finer, and in other respects more valuable article, because the liquor is
introduced without that mischievous degree of agitation which takes place
when the same is poured in at the bung by the common method, and because
the yeast, not being suffered to remain stagnant upon the surface of the liquor
in the cask, is not liable to be absorbed upon any change of the atmosphere,
which is well known to produce injury, foulness, and a bad flavor, by exciting a
second fermentation, and other irregular processes in the same. T is a cock in
the pipe E, E, for the purpose of shutting off the communication and suspending
the operation of tunning whenever the same may be necessary or convenient,

page_text: and more particularly when the tunning is compleated; and V is another cock
for admitting the liquor into S, S, to give effect to the float K, K, as before
described.
In witness whereof, I, the said John Grigory, have hereunto set my hand
and seal, the Nineteenth day of April, in the year of our Lord One
thousand eight hundred and ten.
JOHN GRIGORY." (L.S.)
