page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
HARE, of Limehouse, in the County of Middlesex, Brower, send greeting.
WHEREAS the King's most Excellent Majesty, by His Letters Patent
under His Great Seal of Great Britain, bearing date at Westminster, the
Twelfth day of September, in the thirty-first year of His reign, did give
and grant unto me, the said Richard Hare, His special licence that I, the
said Richard Hare, should and might make, use, exercise, and vend,
within that part of His said Majesty's Kingdom of Great Britain called
England, Dominion of Wales, and Town of Berwick-upon-Tweed, "AN
APPARATUS WHEREBY THE ESSENTIAL OIL OF HOPS, WHICH HE IS INFORMED IS THE
MOST EFFICACIOUS AND PRESERVATIVE PART OF THAT VEGETABLE, AND WHICH TILL
THIS INVENTION WAS LOST AND DISSIPATED IN THE AIR DURING THE OPERATION OF
BOILING WORTS FOR BEER, IS PRESERVED AND APPLIED TO USE; AND THAT BY MEANS
OF THE SAID APPARATUS HIS WATER FOR BREWING IS HEATED TO SUCH A DEGREE OF
HEAT AS HE JUDGES NECESSARY, AND, AS HE BELIEVES, 18 CUSTOMARY, AND THAT HIS
SAID WATER IS HEATED IN LESS THAN HIS USUAL TIME OF BOILING WORTS FOR
BEER, AND THAT WITHOUT ANY APPLICATION OF FIRE TO THE VESSELL CONTAINING
THE SAID WATER;" in which said Letters Patent is contained a proviso, that if
I, the said Richard Hare, did not particularly describe and ascertain the nature.
of my said Invention, and in what manner the same is to be performed, by an
instrument in writing under my hand and seal, and cause the same to be..
inrolled in His said Majesty's High Court of Chancery within one-calendar
month next and immediately after the date of the said Letters Patent, that
then the said Letters Patent, and all libertics and advantages whatsoever
+

page_text: thereby granted, should utterly cease, determine, and become void, anything
therein-before contained to the contrary thereof in anywise notwithstanding, as
in and by the said Letters Patent, relation being thereunto had, may more
fully and at large appear.
NOW KNOW YE, that I, the said Richard Hare, in compliance with the
said proviso, do hereby describe and ascertain the nature of my said Invention,
and the manner in which the same is to be performed, as follows (that is
to say):-
A, the trunk, which incloses the valves; B, the rising valve and frame;
C, the sinking valve, Fig. 3; D, the lever, with its weights to shift occasionally;
E, the valve plate, Fig. 1 and 3, on which the valve frames are fixed, the
valves also are made in it; F, the bottom of liquor back; G, a large cylinder,
connected and communicated with the main copper; H, H, two double-curved
branch pipes, connected with the cylinder G, and opening into the jack back
near its bottom by the valve at a, a, occasionally; I, the straight branch pipe
communicating with the cylinder G, with a curve returned at b, from the
under side, in which is inserted the three pipes c, d, e, with their cocks and
screws, Fig. 3, 1, 2, 3. K, K, jack back or boiling back; L, the boiler
and man-hole. The upright pipe or cylinder G is open into the copper, into
which pipe the steam rises when the copper begins to boil; it is stopt at the
top by the valves B and C; it has free communication into the pipes H, H,
where it may pass into the liquor in the jack back, or not, as thought proper.
It has also a free communication into the straight branch pipe I, with its
three branches, Fig. 2; these three branches have cap screws at their ends,
and cocks so fixed as to be opened when they are wanted. The valves B and C
are reverse, one opens downward; and one opens upward, with adjusting
weights and levers, Fig. 1 and Fig. 3; the one that rises upwards prevents
any overstrain happening to the boiler, and entirely secures it from inward
strains; the valve that opens downward admits the atmosphere to pass into the
boiler, in case it is emptied or cooled too hastily, and perfectly secures the
boiler from any accident happening that way.
In witness whereof, I, the said Richard Hare, have hereunto set my hand
and seal, this Seventh day of October, in the thirty-first 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
RICHARD (L.S.) HARE.
