AN IMPROVED APPARATUS FOR THE BETTER MANUFACTURE OP SUGAR FROM THE CANE
Year: 1827

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, we,' WILLIAM
FAWCETT, of Liverpool, in the County of Lancaster, Engineer, and MATTHEW
CLARK, of the Island of Jamaica, Engineer, do send greeting.
WHEREAS His most Excellent Majesty King George the Fourth, 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 December now
last past, did give and grant unto us, our executors, administrators and assigns,
His special licence, full power, sole privilege, and authority that we, the said
William Fawcett and Matthew Clark, our executors, administrators,' and
assigns, during the term of years therein expressed, should and lawfully might
make, use, exercise, and vend, within England, Wales, and the Town of
Berwick-upon-Tweed, and also in all His Majesty's Colonies and Plantations
abroad, our Invention of "AN IMPROVED APPARATUS FOR THE BETTER MANUFACTURE
OP SUGAR FROM THE CANE;" in which said Letters Patent there" is contained a
proviso, obliging us, or one of us by an instrument in writing under our hand
and seal, fully to describe and ascertain the nature of our said 'Invention,
and the manner in which the same is to be performed, and to cause the same
to be inrolled in His Majesty's Higli Court of Chancery within six calendár
months next and immediately after the date of the said recited Letters Patent,
as in and by the same, reference being 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 Fawcett, do hereby declare that our said improvement is fully
described and ascertained as follows, that is to say :-
Our Invention of an improved apparatus for the manufacture of sugar from
the juice of canes, as produced in tropical climates, or any part of the said
manufacture to which it is applicable, consists in forming an apparatus for the
application of the heat of high pressure steam to the external surfaces of sugar
pans or boilers, which we effect by connecting the sugar pans to, or with, steam
generators or boilers capable of producing high pressure steam, either for this
purpose only or for this purpose in conjunction for the supply of a steam engine
or other object, so that the steam produced from the said generators shall beat
the said sugar pans or boilers; that is to say, our improved apparatus consists
of a combination of the sugar pans and steam generators by which means we
obtain not only sufficient heat to effect the purpose of boiling or granulating
sugar, but also the said steam generator may at the same time be used to
generate the steam requisite for working an engine or other purpose where
such convenience may be required or be desirable for use at the same time.
The accompanying Drawings exhibit our improved apparatus in the form we
have hitherto arranged it to effect our purpose. The Drawing No. 1 contains
a plan and a longitudinal section; A represents a steam generator or boiler
for the production of high pressure steam of sufficient temperature to boil cane
juice; to granulate it into sugar, it may be constructed of malleable iron, of
copper, of of cast-iron; the Drawing shews it of cast-iron; B, wrought-iron
or copper tubes of sufficient capacity to contain the fire flame and smoke
necessary to produce the high pressure steam and these tubes are wholly
immersed in the water and terminate in smoke flues at C, provided with a
regulating damper or dampers D; the sugar pans or boilers of brass or other
suitable metal and also the steam cases, and if more heating surface is
required to perform the operation in a shorter, we add copper tubes E
supplied with steam from the generator and arranged so as to afford the
necessary quantity of additional surface, but to this application of tubes we
do not claim an exclusive right; F, stop valves, to shut off the communication
with the boiler when the tubes are taken out; G, pipes for discharging the
syrup from the pans; H, safety valves; I, a steam pipe for supplying an
engine for a cane mill or other object; K, the feed pipe for supplying the
boiler with water, and L, the float and levers for regulating the supply of water
to the steam generator P, being a continuation of the sugar boilers, but erected
in brickwork, the liquor in which will be heated by the waste heat, as it passes
from the mouth of the flue of the steam boiler or generator to the chimney,

page_text: for which however we claim no exclusive right. In the Drawing No. 2 the
same letters refer to the same parts with the addition M, the platform of
brickwork for the convenience of attending the pans and arched beneath to
give access to the steam generator; N, the steam cylinder of an engine to
work the cane mill O; and K, the pipe to return hot water from the engine to
supply the boiler.
AND BE
REMEMBERED, that on the same Fourth day of June, in
the year above mentioned, the aforesaid William Fawcett came before our Lord
the King in His Chancery, and acknowledged the Specification aforesaid,
and all and every thing therein contained, in form above written. And also
the Specification aforesaid was stamped according to the tenor of the Statute
in that case made and provided.
