IMPROVEMENTS IN THE MANU- FACTURE OF ARTIFICIAL FUEL, COMMONLY CALLED PATENT FUEL
Year: 1859

page_text: LETTERS PATENT to Eugene de Bassano, of Brussells, in the Kingdom of
Belgium, Gentleman, for the Invention of "IMPROVEMENTS IN THE MANU-
FACTURE OF ARTIFICIAL FUEL, COMMONLY CALLED PATENT FUEL."
PROVISIONAL SPECIFICATION left by the said Eugene de Bassano at
the Office of the Commissioners of Patents, with his Petition, on the
1st August 1859.
I, EUGENE DE BASSANO, of Brussells, in the Kingdom of Belgium, Gentle-
man, do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE MANUFACTURE OF ARTIFICIAL FUEL, COMMONLY CALLED PATENT FUEL," to be as
follows:-
This Invention consists in the composition and use of a fatty pitch, composed
of about 90 parts of the common brown resin of commerce, or other crude or
waste resinous substances possessing similar properties, but free from smell,
and containing in the quantity used 90 parts of resinous basis, and of from 2
to 3 parts of any fatty matters or oils having the property of perfect saponifi-
cation, observing that when I use other fatty matters or oils not equally
saponificaceous, I vary the quantity in proportion with their property of
saponifying.
The fatty pitch thus produced is free from all the impurities contained in
the natural substance extracted from coal tar, and commonly used in the hot
process of manufacturing artificial or patent fuel, which said impurities render
such fuel unfit for many purposes on account of the noxious smell and thick
smoke it emits, arising from the presence of napthaline perecic acid, and other

page_text: hurtful substances, as also the lampblack contained in the tar. I would here
observe, that in applying the above-mentioned fatty pitch to the manufacture
of artificial fuel, I do not materially diviate from the method usually employed
in such manufacture, but simply vary the proportions of the aforesaid fatty
pitch according to the quality of the small coal or slack to be operated
upon.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Eugene de Bassano in the Great Seal Patent Office on
the 1st February 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EUGENE
DE BASSANO, of Brussells, in the Kingdom of Belgium, Gentleman, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of August, in the year of our Lord One
thousand eight hundred and fifty-nine, in the twenty-third year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Eugene de Bassano, Her special licence that I, the said Eugene de Bassano,
my executors, administrators, and assigns, or such others as I, the said Eugene
de Bassano, 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 ARTIFICIAL FUEL, COMMONLY CALLED PATENT FUEL," upon the
condition (amongst others) that I, the said Eugene de Bassano, my execu-
tors 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 Eugene de Bassano, 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:-

page_text: This Invention relates to improvements in the manufacture of artificial
fuel commonly called patent fuel, and consists in the composition of a fatty
pitch to be used in and for such manufacture, said pitch being composed of
about 90 parts of the common brown resin of commerce or other crude or
waste resinous substances possessing similar properties thereto, but free from
bad smell, and containing in the quantity used 90 parts of resinous basis con-
tained in various refuse materials or matters, such as may be obtained from
woollen fabrics, tallow, margeric acid, stearic acid, mineral oils, and other
cheap or inferior qualities of oil, and all other bodies or matters possessing the
property, either when mixed together or separately in themselves, of producing
the largest quantity of hydrocarburate, and at the same time of at least from
two to three parts out of every 100 parts of matters possessing the property of
perfect saponification, observing that when the above fatty matters and oils
are used other than those above mentioned, but possessing the same nature
thereas, but not equally as saponificacious, in such cases I vary the quantity
thereof to be employed in proportion to their property of saponification and of
production of hydrocarburate. I reserve to myself the right to use ordinary
coal tar or pitch, or even acid (by preference muriatic acid) in the manufacture
of artificial fuel when the proportion of hydrocarburate and saponificacious
matters which they contain is such as will not cause the emission of noxious
effluvia during the combustion of the fuel prepared therewith.
Having now described and set forth the nature and object of my said
Invention of improvements in the manufacture of artificial fuel, commonly called
"patent fuel," I declare this Invention to consist in, and I claim, the com-
position of a fatty pitch possessing the properties above described, and the use
of the same in and for the manufacture of artificial fuel as above stated.
In witness whereof, 1, the said Eugene de Bassano, have hereunto
set my hand and seal, this Twenty-sixth day of January, in the year
of our Lord One thousand eight hundred and sixty.
Witness,
JOHN PIDDINGTON.
EUGENE DE BASSANO. (L.S.)
