IMPROVEMENTS IN THE MANUFACTURE OF ANIMAL CHARCOAL
Year: 1852

page_text: LETTERS PATENT to Daniel Ebingré, of Brussels, for the Invention.
of "IMPROVEMENTS IN THE MANUFACTURE OF ANIMAL CHARCOAL."
PROVISIONAL SPECIFICATION left by the said Daniel Ebingré, at
the office of the Commissioners of Patents, with his petition, on
the 1st October 1852.
I, JOHN DANIEL EBINGRE, of Brussels, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN THE MANUFACTURE OF ANIMAL
CHARCOAL" to be as follows:-
Heretofore animal charcoal has been largely prepared and used in
filters for the refining of sugar, the same being in a granular form, and
much powder or dust is produced in the manufacture. Now this In-
vention consists of rendering the dust of animal charcoal (whether
produced in the manufacture of the ordinary granular charcoal or by
reducing animal charcoal to powder) into paste, and then into a
granular form.

filed by the said Daniel Ebingré, in the Great Seal Patent Office,
on the 30th March 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
DANIEL EBINGRE, of Brussels, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the first day of October in the year of our
Lord One thousand eight hundred and fifty-two, in the sixteenth year
of Her reign, did for Herself, Her heirs and successors, give and grant
unto me, the said Daniel Ebingre, Her special licence that I, the said
Daniel Ebingre, my executors, administrators, and assigns, or such
others as I, the said Daniel Ebingre, 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 of Great Britain and Ireland, the Channel Islands, and Isle
of Man, an Invention for "IMPROVEMENTS IN THE MANUFACTURE OF
ANIMAL CHARCOAL," upon the condition (amongst others) that I, the said
Daniel Ebingré, by an instrument in writing under my hand and seal,
should particularly describe and ascertain the nature of the said Inven-
tion, 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 Daniel Ebingre, 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):
This Invention consists of rendering the dust of animal charcoal
(whether produced in the manufacture of the ordinary granular charcoal,
or by reducing animal charcoal to powder,) into paste, and then into a
granular form. And in order that my Invention may be most fully
understood, and readily carried into effect, I will proceed to describe the
means pursued by me.

page_text: DESCRIPTION OF THE DRAWING AND PROCESS..
Figure 1, is a side view, Figure 2, an end view, and Figure 3, a plan,
of apparatus such as I prefer to employ, but the same may be varied.
I take any convenient quantity of the powder of animal charcoal, and
combine therewith a quantity of clay, mineral pitch, and water, such
materials being mixed in about the following quantities:
For every 100 lbs. of animal charcoal in powder,
130 lbs. of clay,
4 lbs. of mineral pitch,
100 lbs. water,
and I cause these matters to soak together, well stirring them from
time to time for several days; and this may be conveniently done in a
tub or similar vessel, stirring the matters from time to time; and at the
end of some days, four or five, I pour the matters into the vessel B,.
having in it a stirrer or agitator, put in motion by a strap acting on the
drum c, such strap being put in motion by the drum d, as shown; the
drum d, receiving its motion from the first mover, which in this arrange-
ment is a crank handle, to be moved by hand; but other power may. be
employed, particularly where large quantities of the materials are being
acted on.
The drum d, is on the axis of a stirrer in the tub or vessel,
C, which receives its supply of materials from the vessel B, there being
a suitable opening from one vessel to the other, but closeable by a suit-
able sluice or valve. The materials from the vessel or tub C, are run
into the tub or vessel D, and thence into the vessel E, as will be here-
after fully described. The materials having been well mixed in the
vessel B, they are run into the vessel C, and are there further mixed
by stirring; and from thence they are run into a vessel D, in which
are two grinding stones, which act on and grind the mixture. Motion
is communicated to one of the stones by an axis e, which receives
motion from the axis f, by means of bevelled toothed wheels, as shown.
The axis f, receives motion from a strap, acting on the drum.g, such
strap being put in motion by hand, as shown in respect to the other
parts of the apparatus, or by other power.

page_text: From the vessel D, the mixed materials flow into a tub or receiver
E; when the materials are well ground, and the materials are to be
ladled out of the vessel E, and placed in brown paper spread over 'a
tray, formed by parallel bars, which I place in a drying stove, heated
to about one hundred and four degrees of Fahrenheit, and when dry the
matters are to be divided by a cutting instrument. The matters thus
prepared are to be carbonized, together with a quantity of bones (deprived
of their fat) say at the rate of about seventy-six parts by weight of
the composition above described to one hundred and twenty-four parts
by weight of bones; and I cause these materials to be calcined in like
manner to what bones have heretofore been calcined. I cause the cal-
cined product to granulate as heretofore when treating calcined bones
only, and the same will be fit for like uses as granulated animal
charcoal..
In the above description I have been particular in giving an exact
statement of the apparatus used by me, and of the process as I carry
it on; but I would remark that I do not confine myself thereto, as
the same may be varied without departing from my Invention, which
I declare to consist of rendering the dust of animal charcoal (whether
produced in the manufacture of the ordinary granular charcoal or by
reducing animal charcoal into powder) into paste, and then into a
granular form.
In witness whereof, I, the said Daniel Ebingre, have hereunto set
my hand and seal, this Twenty-first day of March in the year
of our Lord One thousand eight hundred and fifty-three.
DANIEL EBINGRE. (L.S.)
Witness, Euge ESCUDIÉ.
