IMPROVEMENTS IN MOOD PRODUCING AND REVIVIFYING ANIMAL CHARCOAL
Year: 1858

page_text: LETTERS PATENT to Charles Frederick Parsons, of Duke' Street, in the
County of Middlesex, Engineer, for the Invention of "IMPROVEMENTS IN
MOOD PRODUCING AND REVIVIFYING ANIMAL CHARCOAL."
Sealed the 1st September 1858, and dated the 5th March 1858.
PROVISIONAL SPECIFICATION left by the said Charles Frederick Parsons
at the Office of the Commissioners of Patents, with his Petition, on
the 5th March 1858.
I, CHARLES FREDERICK PARSONS, of Duke Street, in the County of Mid-
dlesex, Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINERY FOR PRODUCING AND REVIVIFYING ANIMAL CHARCOAL,"
to be as follows:-
The object of my Invention is to obtain an extended surface whereon to
expose the bones to be burnt, or the charcoal to be revivified, and from which
the atinosphere is excluded, in order to prevent combustion of the bones or
charcoal.
My machinery consists of a circular frame, in the lower part of which I fix
one or more furnaces, and by flues pass the heat round the frame, and into a
chimney or shaft common' to both or all of the flues: Over the furnace and
flues there is a metal disc or platform with a central aperture, and' the rings or
flanges in which the edges of the plates forming the disc or platform are con-

page_text: nected or terminate, are free to revolve in sand troughs. The central aperture
opens into a fixed spout leading to the side of the frame, the outlet being
closed by a tight fitting door or valve. There is a cover fitted perfectly tight
over the revolving platform; spreaders and spreading rollers are fixed between
the cover and the upper surface of the platform, for the purpose of distributing
the material to be operated upon evenly ton.
The feeding hopper extends down through the cover nearly to the surface of
the platform; it is fitted with a valve or slide to prevent the access of air.
Two or more ventilating pipes are fitted into the cover, and are provided with
valves opening outwards, for the purpose of allowing the escape of the matters
given off by the material under treatment, and for convenience these valves
communicate through pipes with the furnace shaft. The platform is connected
by arms to a central shaft, to which rotary motion is communicated by any of
the well known means now adopted for such purposes. As soon as the matters
have been sufficiently exposed to the action of the heat on the platform an
angular guide is let down upon the surface thereof, whereby the matters are
guided off the platform down into the central spout to be withdrawn from the
machine. On commencing operations a gas or other flame or agent may be
introduced to consume or draw off all the oxygen which may be inside the
machine.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Charles Frederick Parsons in the Great Seal Patent Office
on the 4th September 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
FREDERICK PARSONS, of Duke Street, in the County of Middlesex, Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of March, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-first year of Her
reigu, did, for Herself, Her heirs and successors, give and grant unto me,
the said Charles Frederick Parsons, Her special licence that I, the said
Charles Frederick Parsons, my executors, administrators, and assigns, or such
others as I, the said Charles Frederick Parsons, my executors, administrators,
and assigns, should at any time agree 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

page_text: of Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "IMPROVEMENTS IN MACHINERY FOR PRODUCING AND REVIVIFYING
ANIMAL CHARCOAL," upon the condition (amongst others) that I, the said Charles
Frederick Parsons, 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 Charles Frederick Parsons, 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:-
The object of my Invention is to obtain an extended surface whereon to
expose
the bones to be burnt, or the charcoal to be revivified, and from which
the atmosphere is excluded, in order to prevent combustion of the bones or
charcoal.
My machinery is illustrated in the annexed Drawings, Figure 1 being a
front elevation; Figure 2, a vertical section; Figure 3, a top plan view; and
Figure 4, a partial horizontal section through the line a, b, of Figure 2. It
consists of a circular frame A, A, in the lower part of which I fix one or more
furnaces B, B, and by flues C, C, pass the heat round the frame and into a
chimney or shaft common to both or all of the flues. Over the furnace and
flues there is a metal disc or platform D, with a partial circular aperture, and
the bottom rings or flanges c, c, which are attached to the edges of the disc or
platform D are free to revolve in sand troughs d, d. Other flanges or rims e, e,
revolve in additional sand troughs f, f. The aperture opens into a fixed
spout E leading to the side of the frame, the outlet F being closed by a tight
fitting door or valve. There is a cover G fitted perfectly tight over the
revolving platform D. Spreaders H, H, and spreading rollers I, I, are fixed
between the cover and the upper surface of the platform, for the purpose of
distributing the material to be operated upon evenly thereon. The feeding
hopper K extends down through the cover nearly to the surface of the plat-
form; it is fitted with a valve or slide to prevent the access of air. Two or
more ventilating pipes L, L, are fitted into the cover, and are provided with
valves g, g, opening outwards, for the purpose of allowing the escape of the
matters given off by the material under treatment; and for convenience
these valves communicate through pipes M, M, with the furnace shaft. The

page_text: platform is connected to a central shaft N, and rotary motion is communicated
through teeth h, h, formed on the under side of the edge of the platform, in
gear with a small toothed wheel on the shaft O, passing through the side of
the apparatus, and supported in bearings- formed in the support P; which
shaft O receives motion from any prime mover, or motion may be communi-
cated to the shaft N by any of the well-known' means now adopted.
*As soon as the matters have been sufficiently exposed to the action-of-the
heat on the platform D, the matters are guided off the platform down into the
central spout E to be withdrawn from the machine. On commencing opera-
tions a gas or other flame or agent may be introduced to consume or draw off
all the oxygen which may be inside the machine.
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 the construction
of machinery for producing and revivifying animal charcoal, essentially as
herein-before described; and illustrated in the Drawings hereunto annexed.
In witness whereof, I, the said Charles Frederick Parsons, have hereunto
set my hand and seal, this Third day of September, One thousand
eight hundred and fifty-eight.
