Year: 1865

page_text: LETTERS PATENT to Richard Archibald Brooman, of 166, Fleet Street,
in the City of London, Patent Agent, for the Invention of "A NEW
OR IMPROVED METHOD OF DISSOLVING PITCH."-A communication. from
abroad by François Celestin Armelin, of Paris, France..
Sealed the 2nd January 1866, and dated the 4th July 1865.
PROVISIONAL SPECIFICATION left by the said Richard Archibald Brooman
at the Office of the Commissioners of Patents; with his Petition, on the
4th July 1865.
I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, Patent Agent, do hereby declare the nature of the said Invention
for "A NEW OR IMPROVED METHOD OF DISSOLVING PITCH," to be as follows:-
Pitch is now employed, among other uses, in the manufacture of blocks of
artificial fuel to bind the combustible matters and increase the heating power.
Now this Invention consists in a method of fusing or dissolving pitch in the
form of a liquid solution thinned with water, as hereafter described, whereby
the volume of the pitch is increased and great economy thereof in the
manufacture of fuel effected.

page_text: The pitch is formed into a liquid solution as follows:-I pour into a boiler
water and naphthaline, or heavy oil arising from the distillation of coal or
other combustible; I boil, and then add the pitch, taking care to stir the
materials well together; after the boiling has been continued for about 20 or
30 minutes I obtain an intimate admixture of the pitch and water in the form
of liquid pitch, which may be immediately employed in the manufacture of
artificial fuel.
The L
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 4th January 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of London, Patent
Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of July, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-ninth 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, or
such others as I, the said Richard Archibald Brooman, my executors, adminis-
trators, 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 "A NEW OR IMPROVED METHOD OF DISSOLVING PITCH," (com-
municated to me from abroad by François Celestin Armelin, of Paris,
France,) 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 par-
ticularly 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

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:-
Pitch is now employed, among other uses, in the manufacture of blocks of
artificial fuel to bind the combustible matters and increase the heating power.
Now this Invention consists in a method of fusing or dissolving pitch in the
form of a liquid solution thinned with water, as hereafter described, whereby
the volume of the pitch is increased and great economy thereof in the
manufacture of fuel effected.
The pitch is formed into a liquid solution as follows:-I pour into a boiler
water and naphthaline, or heavy oil arising from the distillation of coal, bog-
head schists, or other combustible; I boil on a fire or with steam by means of
a serpentine coil or in a vessel with a double bottom, or otherwise, and I then
add the pitch, taking care to stir the materials well together. Boiling takes
place in about 20 to 60 minutes, varying according to the quantity and the
nature of the substances employed, and after it has been kept up for about
15 to 20 minutes, care being taken to stir the mixture well, I obtain an
intimate admixture of the pitch and water in the form of liquid pitch, which
may be immediately employed while hot in the manufacture of artificial
fuel.
The following proportions have been found to answer well, but I do not

In witness whereof, I, the said Richard Archibald Brooman, have
hereunto set my hand and seal, this Third day of January, One.
