Year: 1858

page_text: LETTERS PATENT to Richard Archibald Brooman, of 166, Fleet Street, in
the City of London, E. C., Patent Agent, for the Invention of "IMPROVE-
MENTS IN THE PREPARATION OF COAL AND OTHER FUEL,"-A communication
from A. M. M. de Bergevin and E. C. Salva, of Paris.
Sealed the 11th July 1858, and dated the 13th January 1858.
PROVISIONAL SPECIFICATION left by the said Richard Archibald
Brooman at the Office of the Commissioners of Patents, with his Petition,
on the 13th January 1858.
I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, E. C., Patent Agent, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN THE PREPARATION OF COAL AND OTHER FUEL," a
communication from A. M. M. de Bergevin and E. C. Salva, of Paris, to be
as follows:-
The object of this Invention is to prepare coal and other fuel in such
manner that when burnt in stoves or furnaces of any ordinary description,
their heating powers shall be increased, and the emission of black smoke,
and also of certain noxious vapours or gases, prevented. And the Invention
consists in preparing coal and other fuel with one or other of the following
substances, mixtures, or compounds.
1. Carbonate of manganese combined with sulphate of alumina, in the
proportions of 2 parts of each to every 100 parts by weight of coal, &c.
The use of this compound prevents the emission of black smoke, keeps
the combustion from becoming too rapid, and augments the heat given out...

page_text: 2. Hydrochlorate of manganese combined with carbonate of potassa, or of
soda, in the proportions of 1½ parts of each to every 100 parts by weight of
coal, &c. The use of this compound produces the same effects as the use of
No. 1, but in a higher degree.
3. Binoxide of manganese combined with carbonate of soda, in the pro-
portions of two parts of the former and 1½ of the latter to every 100 parts by
weight of coal, &c. This compound is peculiarly applicable to fuels which
evolve a great deal of dense black smoke when first fed to a fire.
.
4. Steam. The use of steam injected repeatedly, is found by the Inventors
to produce advantageous effects under some conditions.
5. Nitrate of soda combined with oxide of iron, in the proportions of
1 parts per cent. of the nitrate dissolved at 2° of Baumé, and 2 per cent.
of the oxide, the whole carefully diluted in from 80 to 100 parts of water.
This last compound is preferred by the Inventors as the most economical
and convenient for use.
Either of the foregoing combinations which may be selected for use, is
to be diluted with about 80 or 100 parts of water in order to render it capable
of being mixed easily with the fuel, which may be done as the coal is delivered
at the mine, or at any other convenient time, and in any suitable manner.
In cases where it is desirable to obtain a perfume from the fuel as it is
burnt, essence of lavender, or one or other of the products obtained by dis-
tilling coal tar, and afterwards rectified, may be added in the proportion of
part per cent. to the foregoing substances.
The proportions above given may be varied.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Archibald Brooman in the Great Seal Patent Office
on the 18th July 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of London, E. C.,
Patent Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of January, in the year of our
Lord One thousand eight hundred and fifty-eight, in the twenty-first year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Richard Archibald Brooman, Her special licence that I, the
said Richard Archibald Brooman, my executors, administrators, and assigns,

page_text: or such others as I, the said Richard Archibald Brooman, 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 PREPARATION OF COAL AND OTHER
FUEL," (a communication from A. M. M. de Bergevin and E. C. Salva, of Paris,)
upon the condition (amongst others) that I, the said Richard Archibald
Brooman, 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 Richard Archibald Brooman, 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
The object of this Invention is to prepare coal and other fuel in such
manner that when burnt in stoves or furnaces of any ordinary description,
their heating powers shall be increased, and the emission of black smoke, and
also of certain noxious vapours or gases prevented. And the Invention con-
sists in preparing coal and other fuel by combining the same with one or
other of the following substances, mixtures, or compounds.
First, carbonate of manganese combined with sulphate of alumina, in the
proportions of about two parts of each to every one hundred parts by weight
of coal or other fuel. The use of this compound prevents the emission of
black smoke, keeps the combustion from becoming too rapid, and augments
the heat given out.
Second, hydrochlorate of manganese, or chloride of manganese combined
with carbonate of potassa or of soda, in the proportions of about 1 parts of
each to every one hundred parts by weight of coal or other fuel. The use of
this compound produces the same effects as the use of the first, but in a
higher degree.
Third, binoxide of manganese combined with carbonate of soda, in the
proportions of about two parts of the former and 14 of the latter to every one
hundred parts by weight of coal or other fuel. This compound is peculiarly
applicable to fuels which evolve a great deal of dense black smoke when first
fed to a fire.

page_text: Fourth, nitrate of soda (calcined if desired), combined with oxide of iron,
in the proportions of about 1½ parts per cent. of the nitrate dissolved at 2° of
Baumé, and 2 per cent. of the oxide, the whole carefully diluted in from
.80 to one hundred parts of water. This last compound is preferred by the
Inventors as the most economical and convenient for use. Either of the
foregoing combinations which may be selected for use, is to be diluted with
about 80 or 100 parts of water in order to render it capable of being mixed
easily with the fuel, which may be done as the coal is delivered at the mine,
or at any other convenient time, and in any suitable manner. In cases where
it is desirable to obtain a perfume from the fuel as it is burnt, essence of
lavender, or one or other of the products obtained by distilling coal tar, and
afterwards rectified, may be added in the proportion of about part per cent.
to the foregoing substances. The proportions above given may be varied,
and any of the substances, mixtures, or compounds herein-before mentioned
may be replaced by others which will produce equivalent results.
And having now described the nature of the said Invention, and in what
manner the same is to be performed, I declare that I claim, the preparation
of coal and other fuel by combining the same with one or other of the sub-
stances,mixtures, or compounds herein-before described, in the manner and
for the purposes herein-before set forth.
In witness whereof, I, the said Richard Archibald Brooman, have here-
unto set my hand and seal, this Thirteenth day of July, One thousand
eight hundred and fifty-eight.
