IMPROVEMENTS IN THE MANUFACTURE OF ARTIFICIAL FUEL
Year: 1867

page_text: LETTERS PATENT to Nicolas Rausch and Edmé Léon Darlet, both of the
City of Brussels, in the Kingdom of Belgium, Merchants, for the Invention
PROVISIONAL SPECIFICATION left by the said Nicolas Rausch and Edmé
Léon Darlet at the Office of the Commissioners of Patents, with their
Petition, on the 5th June 1867.
We, NICOLAS RAUSCH and EDMÉ LÉON DARLET, both of the City of Brussels,
in the Kingdom of Belgium, Merchants, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN THE MANUFACTURE OF ARTIFICIAL FUEL,"
to be as follows:-
The fuel is composed by mixing any kind of ordinary coal with argillaceous
or any other earth, or earths possessing similar or analogous properties, chloride
of sodium, and mucilage made by boiling flax or linseed in water to the con-
sistence of a thin syrup. The mixture is made by first adding to the coal
about one-tenth part by weight of the argillaceous or other earth or earths,
then adding about one two-hundredth part by weight of chloride of sodium,.

page_text: and lastly, the mucilage, in the proportion of about one three-hundredth part
by weight; these proportions are approximative only, and may be varied
according to the nature of the coal under treatment. The fuel thus made
can be used as loose or small coal, and either in a dry or wet state, or it may
be agglomerated into, blocks of any size and form by pressure or otherwise.
SPECIFICATION filed in pursuance of the conditions of the Letters. Patent,
and of an Order of the Lord Chancellor, by the said Nicolas Rausch
and Edmé Léon Darlet in the Great Seal Patent Office on the 17th
December 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, NICOLAS
RAUSCH and EDME LÉON DARLET, both of Brussels, in the Kingdom of
Belgium, Merchants, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of June, in the year of our Lord One
thousand eight hundred and sixty-seven, in the thirtieth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
Nicolas Rausch and Edmé Léon Darlet, Her special licence that we, the
said Nicolas Rausch and Edmé Léon Darlet, our executors, administrators,
and assigns, or such others as we, the said Nicolas Rausch and Edmé. Léon
Darlet, our 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," upon the condition (amongst others) that we, the said
Nicolas Rausch and Edmé Léon Darlet, our executors or administrators, by
an instrument in writing under our, or their, ar 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 causo
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 we, the said Nicolas Rausch and Edmé Léon
Darlet, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and
ascertained in and by the following statement (that is to say):

page_text: Our said Invention consists in certain improvements whereby artificial fuel
can be manufactured possessing qualities of a very superior order so far as its
combustible properties are concerned, whilst its use is unattended by those
objections which attach to many other descriptions of artificial. fuel in a
hygienic point of view.
The fuel is composed by mixing any kind of ordinary coal with argillaceous
or any other earth or earths possessing similar or analogous properties, or, by
preference, with peat earth, together with chloride of sodium and mucilage,
the latter being formed by boiling flax or linseed, or, by preference, carragheen
moss or other moss, or lichen possessing analogous properties, in water, to the
consistence of a thin syrup. The proportions in which these several sub-
stances are combined together may be varied according to the nature of the
coal under treatment, and the degree of cohesion which it is desired the fuel
shall possess. The following proportions may, however, be taken as approxi-
matively correct assuming that peat earth and carragheen moss or other moss or
lichen be respectively substituted for argillaceous earth and flax or linseed.
One thousand kilogrammes by weight of small coal are mixed with ten
kilogrammes by weight of peat earth, and two and a half kilogrammes by
weight of chloride of sodium, cohesion being obtained by employing a mucilage
prepared from carragheen moss or other moss or lichen possessing similar or
analogous properties, the moss or lichen being used in 'the proportion of one
kilogramme by weight of the coal employed in the formation of the fuel.
If argillaceous ar such other earth or earths as herein-before mentioned and
flax or linseed be used, the proportions of the materials of which the fuel is
composed will be varied. In such case the mixture is made by adding to the
coal about one-tenth part by weight of the argillaceous or other earth or
earths, then adding about one two-hundredth part by weight of chloride of
sodium; and, lastly, the mucilage in the proportion of about one three-hundredth
part by weight.
The materials having been thus combined the fuel can be used as loose or
small coal, and either in a dry or wet state, or it may be agglomerated into
blocks of any size and form by means of pressure imparted thereto by any
mechanical contrivance adapted for the purpose.
Having thus declared and ascertained the nature of our said Invention, and
the manner in which it is to be performed, we would observe in conclusion
that what we consider novel and original, and therefore claim as constituting
the Invention secured to us by the said herein-before in part recited Letters
Patent, is, the combination of materials herein-before mentioned for the

page_text: formation of artificial fuel in the manner and proportions substantially
berein-before described and set forth, or any mere modifications thereof.
In witness whereof, we, the said Nicolas Rausch and Edmé Léon
Darlet, have hereunto set our hands and seals, this Fourth day of
December, in the year of our Lord One thousand eight hundred and
sixty-seven.
