IMPROVEMENTS IN COOLING AND SIPTING GROUND ANIMAL CHARCOAL AFTER IT HAS BEEN REBURNED, AND IN APPARATUS EMPLOYED FOR THIS PURPOSE, AND FOR RAISING GROUND ANIMAL CHARCOAL TO ANY DESIRED HEIGHT
Year: 1869

page_text: LETTERS PATENT to George Henry Tayler Finzel, of the City of
Bristol, Sugar Refiner, for the Invention of "IMPROVEMENTS IN
COOLING AND SIPTING GROUND ANIMAL CHARCOAL AFTER IT HAS BEEN
REBURNED, AND IN APPARATUS EMPLOYED FOR THIS PURPOSE, AND FOR RAISING
GROUND ANIMAL CHARCOAL TO ANY DESIRED HEIGHT."
Sealed the 4th May 1869, and dated the 9th March 1869.
PROVISIONAL SPECIFICATION left by the said George Henry Tayler
Finzel at the Office of the Commissioners of Patents, with his
Petition, on the 9th March 1869.
I, GEORGE HENRY TAYLER FINZEL, of the City of Bristol, Sugar
Refiner, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN COOLING AND SIFTING GROUND ANIMAL CHARCOAL APTER IT HAS BEEN
REBURNED, AND IN APPARATUS EMPLOYED FOR THIS PURPOSE, AND FOR RAISING
GROUND ANIMAL CHARCOAL TO ANY DESIRED HEIGHT," to be as follows:-
In sugar refinerys ground animal charcoal after it has been reburnt
requires to be cooled and sifted before it is fit to be again used for the

page_text: filtering of syrup, the charcoal cylinders or cisterns employed to contain
the ground charcoal are also frequently of considerable height, and the
charcoal with which they are to be filled has to be raised to the level of.
the tops of the cylinders or cisterns to be fed into them.
Now according to my Invention I cool and sift the ground animal
charcoal after it has been reburnt, and at the same time raise it to the
desired elevation by feeding it into a pipe or shaft up through which a
current of air is caused to pass; the current of air is sufficiently rapid to
carry the charcoal along with it, and the charcoal is by this means
raised to the desired height at the same time that it is cooled; the upper
end of the pipe or shaft opens into a chamber, and the charcoal as it
issues from the pipe is checked by striking against a fixed surface, which
is by preference of soft material or padded, so that the grains of charcoal
may not be broken; the larger particles of the charcoal fall on to the
floor of the chamber, whilst the dust passes off with the air into a second
chamber, which may be partly enclosed by fine sieves, and in this
chamber the dust is collected. The animal charcoal after reburning is
placed in cannisters as usual, or is otherwise allowed to cool down to
some extent before it is fed into the air blast. The same apparatus may
also be employed for raising ground animal charcoal to the desired
height for feeding into the cylinders or cisterns.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Henry Tayler Finzel in the Great Seal
Patent Office on the 7th September 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HENRY TAYLER FINZEL, of the City of Bristol, Sugar Refiner, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Ninth day of March, in the year of
our Lord One thousand eight hundred and sixty-nine, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said George Henry Tayler Finzel, Her

page_text: special licence that I, the said George Henry Tayler Finzel, my executors,
administrators, and assigns, or such others as I, the said George Henry
Tayler Finzel, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Invention
for "IMPROVEMENTS IN COOLING AND SIFTING GROUND ANIMAL CHARCOAL AFTER IT
HAS BEEN REBURNED, AND IN APPARATUS EMPLOYED FOR THIS PURPOSE, AND FOR
RAISING GROUND ANIMAL CHARCOAL TO ANY DESIRED HEIGHT," upon the con-
dition (amongst others) that I, the said George Henry Tayler Finzel,
my executors or administrators, by an instrument in writing under my,
or their, or one of their hands and seals, should particularly describe
and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the
Great Scal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.

NOW KNOW YE, that I, the said George Henry Tayler Finzel, do
hereby declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in
and by the following statement thereof, that is to say :-
In
sugar refineries animal charcoal after it has been reburnt requires
to be cooled and sifted before it is fit to be again used for the filtering
of syrup, the cisterns or filtering vessels employed to contain the char-
coal are also frequently of considerable height, and the charcoal with
which they are to be filled has to be raised to the level of the tops of
the cisterns to be fed into them.
Now according to my Invention I cool and sift animal charcoal after
it has been reburnt and at the same time raise it to the desired elevation
by feeding it into a pipe or shaft up through which a current of air is
caused to pass, the current of air is sufficiently rapid to carry the char-
coal along with it, and the charcoal is by this means raised to the
desired height at the same time that it is cooled, the upper end of the
pipe or shaft opens into a chamber, and the charcoal as it issues from
the shaft or pipe falls upon the floor of the chamber whilst the dust
passes off with the air into a second chamber where it is collected. The

page_text: same apparatus may also be employed for raising animal charcoal to the.
desired height for feeding into the cisterns.
In witness whereof, I, the said George
the said George Henry Tayler Finzel,
have hereunto set my hand and seal, this Sixth day of Septem-
ber, in the year of our Lord One thousand eight hundred and
sixty-nine.
GEORGE HENRY TAYLER FINZEL. (L.S.)
