page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
FRANCIS HAMILTON, of Lower Mount Street, in the City of Dublin,
Gentleman, do send greeting.
WHEREAS His most Excellent Majesty King George the Third by His
Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Fourth day of May
now last past, did give and grant unto me, the said William Francis
Hamilton, my executors, administrators, and assign, His special licence, full
power, sole privilege and authority, that I, the said William Francis Hamilton,
my executors, administrators, and assigns, should and lawfully might make,
use, exercise, and vend, within England, Wales, and Town of Berwick-upon-
Tweed, my Invention of "A NEW MODE OP PREPARING SODA AND OTHER MINERAL
WATERS, SPIRITUOUS, ACETOUS, SACCHARINE, AND AROMATIC LIQUEURS, AND SUNDRY
IMPROVEMENTS RELATIVE THERETO;" in which said Letters Patent there is contained
a proviso, obliging me, the said William Francis Hamilton, 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 six calendar months next and
immediately after the date of the said in part recited Letters Patent, as in
and by the same, relation be thereunto had, may more fully and at large
appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
William Francis Hamilton, do hereby declare that my said Invention is
fully described and ascertained in manner following, that is to say:-
I use various solutions of alkalies, salts, &c., and combinations of ardent
spirits, vegetable acids, aromatic oils, sugars, milk, mucilage, &c., for saturation
and supersaturation, with carbonic acid. I obtain my gas from the decomposi-
tion of whiting with dilute sulphuric acid, applying the whiting in a liquid state,
to admit of its introduction to the laboratory, in which the carbonic acid is
disengaged with facility and cleanliness; the gypseous residuum I let off also
liquid. I expose the solution, &c. in a strong well-tinned copper vessel,
under more or less pressure, for the absorption of fixed air, which may be
effected (by its suffering considerable agitation in a cold bath suspended by
pendulous tubes) without interruption to the injection of solution, &c. from
a condensing syringe on discharge of aerated liquor from a decanting stop-
cock, so that the bottling can exist continually. I use a piston solid and
cylindrical, fitted with a thin collar of leathers, at the lower extremity of the
pump; it forces upwards, causing the proportionate supply of liquid matter,
which is injected by it at the same time with the carbonic acid, to serve as a
lute to the collar of leathers already nearly air-tight. This principle of liquid
luting I apply in every possible instance. The valves, I sometimes-place in
the plugs of the acting stop-cock, so that if they get out of order they can be
easily ground air-tight again by withdrawing the plugs, in which case the
charge may still be preserved in the vessel. by means of another sett of stop-
cocks, placed nearer to it and used only on such occasions, or when it is
necessary to anoint the acting ones with a composition of oleaginous wax,
tallow, &c. I generally-use-a-glass-or-earthen-bottle-or-jar-of-a-long-ovate-
form, for several reasons, viz, not having a squaro bottom to stand upon,
it can only. lie on its side, of course, no leakage of air can take place, the
liquid matter being always in contact with the stopper. It permits its con-
tents to be poured out more easily, and consequently with less loss of fixed
air. It can be much stronger than a bottle or jar of equal weight made
in the usual form, and is therefore better adapted for packing, carriage, &c.
The neck of the bottle and mouth are sometimes so formed that it may serve.
instead of a drinking glass if necessary. I commonly stop with cork, which,
from the excessive pressure generally existing within the bottle, flies out on
the detaining strings being cut; but sometimes I use glass or earthen stoppers,
fitted conically in the usual way, or ground in across the neck. I also
occasionally use stoppers of various ligneous matter, closing the pores with

page_text: coatings of insoluble compounds. I generally saturate under a pressure of
120 lbs. p. square inch, which is somewhat reduced on the liquors being
bottled The decantation is effected by stopping the mouth of the bottle or
jar with a perforated flat cork, leather, &c., through which passes the
decanting tube, so that on opening the cock the aerated liquor rushes into
the bottle or jar, till resisted by the condensation of the atmospheric air it
originally contained, and a portion of carbonic acid gas extricated during the
effort. The decantation is continued by suffering this condensed air to escape,
and when full the bottle or jar may be withdrawn and stopped with ease by
letting off slowly a small portion of the fixed air contained before its removal.
Sometimes I construct the decanting cock so as to allow the stopper to pass
into the bottle or jar previous to its removal from the flat air-tight fitting,
by which means the entire pressure, how great soever, may be altogether
retained.
In witness whereof, I, the said William Francis Hamilton, have
hereunto set my hand and seal, this Twenty-eighth day of October,
One thousand night handdad
W. F. HAMILTON. (L.B.).
AND BE IT REMEMBERED, that on the Twenty-eighth day of October,
in the fiftieth year of the reign of Ilis Majesty King George the Third,
the said William Francis Hamilton came before our said Lord the King
in His Chancery in Ireland, and acknowledged the instrument aforesaid, and
all and every thing therein contained and specified, in form above written.
And also the instrument aforesaid was stamped according to the tenor of the
Statute made in the forty-eighth year of His said Majesty's reign.
