A NEW APPARATUS FOR GRANULATING SUGAR
Year: 1830

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
RICHARD GUPPY, send greeting.
WHEREAS I, the said Thomas Richard Guppy, of the City of Bristol, Sugar
Refiner, did, by Petition, humbly represent to His lato most Excellent Majesty
King George the Fourth that I had invented "A NEW APPARATUS FOR
GRANULATING SUGAR," which I believed would be of public utility, and had
never been practised by any other person or persons whomsoever, and of which
I was the first and sole Inventor; and whereas I humbly prayed His said late.
Majesty to grant unto me, my executors, administrators, and assigns, His.
Royal Letters Patent, under His Great Seal of Great Britain, for the sole use,
benefit, and advantage of my said Invention within that part of His said lato
Majesty's Kingdom of Great Britain called England, His Dominion of Wales,
and Town of Berwick-upon-Tweed, and also in all His said late Majesty's..
Colonies and Plantations abroad, for the term of fourteen years, according to
the Statute in that case made and provided; and whereas His said late
Majesty, being willing to give encouragement to all inventions that might be
for the public good, was graciously pleased to condescend to my request, and..
by His Royal Letters Patent, bearing date at Westminster, the Sixth day of
March last, in the eleventh year of His reign, of His especial grace and mere
motion, did give and grant unto me, the said Thomas Richard Guppy, my
executors, administrators, and assigns, His especial licence, full power, sole pri-
vilege and authority, that I, the said Thomas Richard Guppy, my executors,

page_text: administrators, and assiдns, and every of us, by myself or themselves, or by
mine or our deputy or deputies, servants or agents, or such others as I, the said
Thomas Richard Guppy, mý exors, administrators, 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 my said Invention within that said part of His said late
Majesty's said Kingdom of Great Britain called-England, and- His Dominion
of Wales, and Town of Berwick-upon-Tweed, and also in all His said late
Majesty's Colonies and Plantations abroad, in such manner as to me, the said
Thomas Richard Guppy, my executors, administrators, and assigns, or any of
us, should in our discretion. seem meet; and that I, the said Thomas Richard
Guppy, my exors, admiors; and assigns, should and lawfully might have and
enjoy the whole profit, benefit, commodity, and advantage from time to time
coming, growing, accruing, 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, privileges, and advantages therein-before granted or
-mentioned to be granted unto me, the said Thomas Richard- Guppy, my
executors, administrators, 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 complete and ended, according to the
Statute in such case made and provided; and whereas in the said Letters
Patent there is contained a proviso that if I, the said Thomas Richard Guppy,
should not particularly describe and ascertain the nature of my said Invention,
and also 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 enrolled in His
said late Majesty's High Court of Chancery within six calendar months next
immediately after the date of the said Letters Patent, that then the said
Letters Patent, and all liberties and advantages whatsoever 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, reference-being-thereunto-had, will more fully and
at large appear.
NOW KNOW YE, that, in compliance with the said proviso, I, the said
Thomas Richard Guppy, do hereby declare the nature of my said Invention to
consist in 'allowing air to pass thro' those fluids known in the sugar trade by
the names of liquor, syrup, or cane juice, while undergoing the process called
boiling, by means of an apparatus which causes a continued supply of air to
be drawn from an external atmosphere into and thro' the fluid, and thence
into an air chamber, receiver, or passage; placed in a situation above the fluid

page_text: Invention is to be performed by the following description thereof, reference
being had to the Drawing annexed, and to the letters marked thereon (that
is to say):
--
DESCRIPTION OF THE DRAWING.
A, A, A, is an ordinary sugar pan. B, B, the brickwork in which it is set.
C, the fireplace; and D, the flue. E, is an iverted vessel or receiver, suspended
over the pan by the supports F, F. This receiver may be of the same material
as the pan. G is a pipe leading to an exhausting apparatus. H is a plate
perforated with small holes, and fixed within the receiver. In order to use
this apparatus, a fire being lighted and kept up in the grate, the exhausting
apparatus should be set to work, and at the same time the pan should be fed
with liquor. As the air is exhausted out of the receiver the liquor will of
course rise in it till it attains the height required, at which time the liquor in
the pan should be on a level with the bottom of the receiver. The supply of
liquor to the pan may then be stopped, and the exhausting apparatus kept at
work, the effect of which will be that a constant supply of atmospheric air will
be drawn under the receiver, and being distributed by the perforated plate,
will pass into and thro' the liquor contained in the receiver till it reaches the
dome head or air chamber at the upper part of it, whence it will be drawn
out by the exhausting apparatus, while fresh portions of air supply its place
from below, and thus I am enabled to boil at any temperature I please,
according to the height of the liquor in the receiver; am also enabled to
maintain that temperature by continuing a supply of liquor to the pan equal
in quantity to the diminution by evaporation and exhaustion, which supply
keeps the column of liquor in the receiver always at the same height.
Now, whereas it is evident that my Invention would be equally effective if
steam were used to heat the liquor, and would act to a certain extent even if
the top of the pan were wholly covered in, and pipes open at one end to the
external air introduced through the sides or top of the pan into the liquor;
for whereas I claim as my Invention the apparatus aforesaid for granulating
sugar, the novelty of which apparatus consists in causing a continuous supply
of air to be drawn from an external atmosphere into and through the liquor
by means of an exhausting apparatus applied to it as aforesaid; and such my
Invention being, to the best of my knowledge and belief, entirely new and
never before used in that said part of His said late Majesty's United Kingdoni
of Great Britain called England, His said Dominion of Wales, and Town of

page_text: Berwick-upon: Tweed, nor in any of: His said late Majesty's Colonies.nor.
Plantations abroad, I do hereby declare this to be my Specification of the said
Invention, and that I do verily believe this my said Specification doth comply
in all respects, fully and without, reserve or disguise, with the proviso in tho
said herein-before in part recited Letters Patent contained; wherefore I do
hereby claim to maintain exclusive right and privilege to my said Invention.
In witness whereof, I have hereunto set my hand and seal, this First
day of September, in the year of our Lord One thousand eight hundred
and thirty.
