Year: 1865

page_text: LETTERS PATENT to Thomas White, of Camden Town, in the County of
Middlesex, Gentleman, for the Invention of "IMPROVEMENTS IN APPARATUS
"
CMFLUIDU IN
"
REBURNING OF ANIMAL CHARCORE.'
THE AUD
Scaled the 27th October 1865, and dated the 29th April 1865.
PROVISIONAL SPECIFICATION left by the said Thomas White at tho
Office of the Commissioners of Patents, with his Petition, on the 29th
April 1865.
I, THOMAS WHITE, of Camden Town, in the County of Middlesex,
Gentleman, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN APPARATUS EMPLOYED IN THE REBURNING OF ANIMAL CHARCOAL," to be
as follows:-
My improvements consist in forming on the inside of cylinders, placed
horizontally or nearly so, a series of scoops or buckets, which on the cylinders
being made to revolve either continuously in the same direction, or partly in
one and partly in the reverse direction, pick up, disperse and transfer the black
from one end of the cylinder to the other. The cylinders are heated, and

page_text: motion is communicated to them in the usual manner. I prefer to employ
more than one cylinder, the cylinders being placed over one another, and the
outlet from one being made to open into the inlet of the cylinder next below
it, and so on. My Invention also consists in the employment of a cooling
cylinder made of thin metal, into which the black is received after being
sufficiently burnt, and in travelling through which it is cooled.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas White in the Great Seal Patent Office on the
28th October 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
WHITE, late of Camden Town, in the County of Middlesex, Gentleman, now
of Philpot Lane, in the City of London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of April, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Thomas White, Her special licence that I, the said Thomas White,
my executors, administrators, and assigns, or such others as I, the said Thomas
White, my executors, administrators, and assigns, should at any time agreo
with, and no others, from time to time and at all times thereafter 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 APPARATUS
EMPLOYED IN THE REBURNING OF ANIMAL CHARCOAL," upon the condition (amongst
others) that I, the said Thomas White, 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 Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
:
NOW KNOW YE, that I, the said Thomas White, do hereby declare the
nature of my 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, reference being had to the Drawings hereunto annexed, that is to
say:-

page_text: My improvements consist in forming on the inside of cylinders, placed
horizontally or nearly so, a series of scoops or buckets, which on the cylinders
being made to revolve either continuously in the same direction, or partly in
one and partly in the reverse direction, pick up, disperse, and transfer the black
from one end of the cylinder to the other. The cylinders are heated and motion
is communicated to them in the usual manner. I prefer to employ more than
one cylinder, the cylinders being placed over one another, and the outlet from
one being made to open into the inlet of the cylinder next below it, and so on.
My Invention also consists in the employment of a cooling cylinder made of
thin metal, into which the black is received after being sufficiently burnt, and
in travelling through which it is cooled.
Figure 1 of the accompanying Drawings is a front elevation, Figure 2 a
longitudinal sectional elevation, and Figure 3 a back elevation of an appa-
ratus for reburning animal charcoal constructed according to my Invention.
A, B, are two horizontal cylinders caused to revolve by any convenient means.
These cylinders are heated by a furnace D; the products of combustion after
heating the cylinders pass through openings or flues K, in the crown of the
furnace arch to the main flue L. The cylinders A, B, are formed on the
inside with a series of scoops W, which, owing to the revolution of the
cylinders, pick up, disperse, and transfer the animal charcoal from one end of
cach cylinder to the other end. E is the charging floor, and F a hopper,
by which the charcoal is fed into the upper cylinder A. Tho charcoal as it
reaches the further end of this cylinder passes through a channel X to the
cylinder B, and after being transferred by the scoops to the other end of the
cylinder B, may be allowed to issue from the machine, or as shown in tho
Drawing it may pass down a shoot G, and pipes T, or one pipe to a cooling
cylinder C. The gas and fine dust are drawn away from the cylinders A, B,
through a pipe M, the dust being then deposited in a chamber, and the gas
carried off by the chimney. The cooling cylinder is shewn in transverse
section in Figure 4; it is also formed with scoops Z, for transferring the
black from one end of the cylinder to the other. The cylinder C may be
driven by a chain or band from the shaft of one of the cylinders A, B, or as
shewn in the Drawing, by independent gearing P. H is the brick setting of
the apparatus.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim as my " Improve-
ments in Apparatus employed in the Reburning of Animal Charcoal" the
employment of reburning and cooling cylinders placed horizontally, or nearly

page_text: so, and formed on the inside with scoops or buckets, all arranged and acting
substantially as herein-before described.
In witness whereof, I, tho said Thomas White, have hereunto set my
hand and seal, this Twenty-fourth day of October, One thousand eight
hundred and sixty-five.
THOMAS WHITE. (L.S.)
