page_text: HERMAN SCHRODER, of Bristol, Gentleman, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria,
by Her Royal Letters Patent under the Great Seal of United
Kingdom of Great Britain and Ireland, bearing date at Westminster,
the Fifteenth day of April, One thousand eight hundred and fifty-one,
in the fourteenth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Herman Schroder, my
exors, adiñiors, and assigns, Her especial license, full power, sole privi-
lege and authority, that I, the said Herman Schroder, my exors,
admors, and assigns, or such others as I, the said Herman Schroder,
my exors, admiors, or assigns, should at any time agree with, and no
others, from time to time and at all times 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 in the Islands of Guernsey, Jersey, Alderney, Sark, and
Man, and also in all Her said Majesty's Colonies and Plantations
abroad, my Invention of "IMPROVEMENTS IN MANUFACTURING AND RE-
PINING SUGAR;" in which said Letters Patent is contained a proviso,
that I, the said Herman Schroder, shall cause a particular description of

page_text: 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, to
be inrolled in Her said 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, reference being
thereunto liad; will more fully and at large appear.
"
NOW KNOW YE, that in compliance with the said proviso, I, the
said Herman Schroder, do hereby declare that the nature of my said
Invention, and the manner in which the same is to be performed, are
fully described and ascertained in and by the following statement
thereof, that is to say:
My Invention relates to combining of apparatus for evaporating and
granulating cane juice or liquids containing saccharine matters capable
of crystalization, and consists of combining a pan or vessel heated by
steam or other heated fluid contained in or passing through a pipe or
series of pipes or passages inserted in or through the pan or vessel em-
ployed with a series of dises or surfaces capable of moving or revolving
partly in the liquid to be evaporated or granulated. The operation is
performed by bringing the heated particles of cane juice or saccharine
liquid into contact with the air by the revolution of the discs, whereby
evaporation to a great extent is carried on at a temperature below the
ordinary boiling point of the liquid. "I prefer the pan or vessel to be
of a segment of a cylinder to any other shape, but I do not confine
myself thereto, as' other shaped vessels may be used, neither do I con-
fine my
Invention to any particular shaped pipe or arrangement of
pipes or presages for conveying heat to the liquid. The arrangement
in the Drawing, and I regulate the tempera-
which is
:a
ture by cocks or other suitable means.
What I claim is, the combination of moving, or revolving discs or
surfaces with pans or vessels heated by pipes, or tubes or passages
containing steam or other heated fluid.
In witness whereof, I, the said Herman Schroder, have hereunto
set. my hand and seal, this Seventeenth day of April, in the
year of our Lord One thousand eight hundred and fifty-one.
HERMAN (L.S.) SCHRODER.
