COMPLETE SPECIFICATION.
The Manufacture of an Improved Artificial Fuel.
I, HENRY PAZOLT, of Ramagen-on-the-Rhine, in the Empire of Germany,
Gentleman, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
This invention relates to the manufacture of a practically smokeless and inodorous
fuel.
The said fuel is manufactured by mixing and combining coal dust or powdered
or granulated coal with dolomite, marl, magnesite, burned lime gypsum, plaster of
paris, or the oxides or hydrated oxides of calcium or magnesium, either alone or
in combination, in the proportion of about one part by weight of earthy matter to
twenty parts of coal-dust, powdered or granulated coal. To the mixture thus
obtained from one to five parts by weight of rice or sugar is added.
In some cases I employ a smaller proportion of earthy matter making up the
difference by the addition of sulphuric acid or petroleum or mineral oil. The
ingredients are thoroughly mixed and incorporated, and the mixture is then moulded
into blocks or briquettes of convenient size by pressure in any of the well known
manners.
I am aware that lime, plaster of paris, and some others of the above mentioned
substances have heretofore been used in combination, as an artificial fuel, but I am
not aware and do not believe that all of them have been so used, nor any of them
in the proportions and combinations above stated.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. The herein described composition of matters to be used as an artificial fuel,
consisting of coal-dust, powdered or granulated coal, dolomite, marl, magnesite,
burned lime, gypsum, plaster of paris or the oxides or hydrated oxides of calcium
or magnesium and rice or sugar, sulphuric acid, petroleum or mineral oil, substan-
tially as set forth.
2. A smokeless and nonodorous composition fuel consisting of coal-dust powdered
or granulated coal, earthy matter such as dolomite, marl, magnesite, burned lime,
gypsum, plaster of paris, the oxides or hydrated oxides of calcium or magnesium,
sulphuric acid rice, sugar, petroleum or mineral oil, substantially as set forth.
3. A smokeless and nonodorous composition fuel, consisting of coal dust,
powdered or granulated coal and dolomite, substantially as set forth.

8. A smokeless and nonodorous composition fuel, consisting of coal-dust,
powdered or granulated coal and marl and petroleum or mineral oil, substantially
as set forth.
