1, GUSTAVE FRANK of 11, Pine Street, in the City of New York, County of New
York and State of New York, United States of America, Banker do hereby declare
the nature of this Invention to be as follows:-
My invention relates to a new and useful composition of substances, whereby an
artificialy prepared fuel is produced capable of yielding intense heat, and at
the same time producing a pleasant and healthful atmosphere in the apartment
where used.
The objects of my invention are to produce, first, an exceedingly cheap, cleanly,
portable, and compactly pressed fuel, that is suitable for all commercial, manufacturing
and domestic purposes, and secondly, a fuel, wherein by the addition of certain
substances of an antiseptic and fragrant nature, the surrounding atmosphere is
rendered healthful, salubrious, and more or less perfumed, according to the tastes
and wishes of the users.
.
My composition, (which I designate as "Diamantine") forming the compressed
artificial fuel, consists of the following ingredients, combined in about the proportions
stated i
Coal dust, or coal in a granular condition
Calcined Brick, or other earthy substances
of like nature
Coal, Tar, Pitch, or other residuum or by-
product of Gas-Works, Oil distilleries,
asphaltum, Resinous substances, or
other Hydro-Carbons in a viscous
-
Fifty parts by weight.

state
To the above composition I add, for making a special domestic fuel, any required
quantity of some aromatic substance, such as sawdust of sandal wood, pines, resinous
fibres or sandarach, which yields a pleasant smell or delicate incense and in some

page_text: cases, and for use under certain circumstances, such as in sick rooms, and in hospitals,
or where sewer gases are prevalent, 1 add any suitable substance that when burnt will
yield antiseptic or disinfecting, properties, such substances being coffee-beans, or
anything possessing similar antiseptic and fragrant elements.
The before-mentioned ingredients of coal and brick are to be reduced to either a
granular or powdered condition and then thoroughly mixed with the pitch, tar, or
other substances by agitation in any suitable pug-mill, having heat furnished to said
mixture by means of exhaust or live steam injected into the agitating apparatus
while in motion, or by heating the said agitator and its contents by constructing the
agitating apparatus with a jacket, and into and around which either steam or hot
water is allowed to flow.
The above described admixture or composition of substances having all been thrown
into and passed through this agitating apparatus, is then submitted to the required
pressure in suitable moulds of any desired shape, or size, and allowed to cool and
harden in the open air. In about three hours these blocks or briquettes are ready for
use and are suitable for stoves, locomotives, or general steam-heating purposes.
The coal dust and granulated or powdered brick, when mixed with the hydro-
carbon substance before named become extremely hard, and thus permit the blocks
to be transported without breakage, and the quantities of each ingredient may be
varied to suit the uses to which it is to be applied, without departing from the principle
and nature of my invention.

Improvements in the Manufacture of Compressed Artificial Fuel.
I, GUSTAVE FRANK, of 11 Pine Street, in the City of New York, County of New
York, and State of New York, United States of America, Banker, 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:-
My invention relates to a new and useful composition of substances, whereby an
artificially prepared fuel is produced, capable of yielding intense heat, and at
the same time producing a pleasant and healthful atmosphere in the apartment
where used.
The objects of my invention are to produce, first, an exceedingly cheap, cleanly,
portable and compactly pressed fuel, that is suitable for all commercial, manufacturing,
and domestic purposes, and secondly a fuel, wherein by the addition of certain
substances of an antiseptic and fragrant nature, the surrounding atmosphere is
rendered healthful, salubrious, and more or less perfumed, according to the tastes
and wishes of the users. The ingredients constituting the said fuel, and the
method of producing the same are hereinafter fully described and pointed out in the
claims.
My composition (which I designate as "Diamantine") forming the compressed
artificial fuel, consists of the following ingredients, combined in about the proportions
stated

page_text: by means of exhaust or live steam injected into the agitating apparatus, while in
motion, or by heating the said agitator and its contents by constructing the agitating
apparatus with a jacket, into and around which, either steam or hot water is allowed
to flow.
The above described admixture, or composition of substances having all been thrown
into and passed through this agitating apparatus, is then submitted to the required
pressure in suitable moulds of any desired shape or size and allowed to cool and
harden in the open air. In about three hours, these blocks or briquettes are ready
for use and are suitable for stoves, steam boilers, or general steam heating
purposes.
The coal dust and granulated or powdered brick, when mixed with the hydro-
carbon substance before named, become extremely hard, and thus permit the blocks
to be transported without breakage. The quantities of each ingredient, may be varied
to suit the uses to which it is to be applied, without departing from the principle and
nature of my invention.
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 composition of a binding or agglomerating material for producing artificial
fuel, consisting of about ten per cent. of coal-tar, or other residuum formed by the
distillation of hydro-carbon substances, and forty per cent. of granulated calcined
brick, or other earthy substance of like nature, substantially as herein described, and
for the purpose set forth.
2. The herein described composition of an artificial fuel, consisting of powdered
coal, and brick, mixed with, and combined by pitch, tar, or other residuum, formed by
the distillation of hydro-carbon substances, in the manner described and in or about
the proportions specified.
3. The addition of any substance yielding when burnt, antiseptic and fragrant
properties to the above admixture of coal-dust brick dust, and pitch, tar, or
other hydro-carbon residuum substantially as described, and for the purposes
specified.
