Complete Specification Accepted, 4th May, 1889
I, GUSTAVE FRANK, of 11 Pine Street, in the City, County 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 combination of ingredients, which, when
properly mixed with suitable carbonaceous substances, and subsequently compressed
will produce an artificial fuel, possessing groat heat-giving properties, without emiting
smoke or noxious gases.
The object of my invention is to produce a clean, portable, and practically flameless
and smokeless fuel, that will burn slowly in any vessel or stove, or in the open air,
and at the same time yield an intense heat.
To carry my invention into effect, I take the following ingredients, which 1 term
"Sestalit" consisting of 95 per cent. of lime (calcined limestone) and 5 per cent. of
Gypsum (or plaster) and make a solution of the same in ten gallons of water.
I then dissolve in another vessel two lbs. of acetate of lead, in an additional
5 gallons of water. When these two solutions are properly dissolved, or mixed, I
throw them both together into one vessel and continue to stir the same until they are
thoroughly combined. I afterwards mix this combined solution with any suitable
carbonaceous substance, until a thickened mass is produced.
In a suitably constructed apparatus, containing agitators, or mixing arms, (which
by preference is cylindrically formed) with a rotating shaft passing through it longi-
tudinally, place a sufficient quantity of finely powdered vegetable charcoal, coke,
coal, or other carbonaceous substances, to absorb the before mentioned fifteen gallon
solution, and the whole is then mixed together by rotary agitation in this cylindrically
formed apparatus, until a thickened mass is produced of about the consistency of stiff
mortar.
This being accomplished, I pass the agglomerated inass through compressing rollers
or any other suitable machinery or apparatus that will press the pasty compound into
blocks, cakes, or balls of any required shape or size, and either perforated or
otherwise

page_text: These blocks or cakes are then dried, either in the open air or by exposure to heat
in any kind of kiln or drying chamber, and are, then ready for use, for either domestic,
commercial, or manufacturing purposes.
The solution above referred to as "Sestalit" not only produces (when mixed with
carbonaceous substance) a safe combustible fuel but effects great cohesion and binds
the whole block together without destroying the necessary porosity of a compact and
perfect composition fuel.

page_text: I, GUSTAVE FRANK, of 11 Pine Street, in the City, County, 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 combination of ingredients, which, when
properly prepared with suitable carbonaceous substances, and subsequently compressed,
will produce an artificial fuel, possessing great heat-giving properties, without emitting
smoke or noxious gases.
The object of my invention is to produce a clean, portable, and practically flameless
and smokeless fuel, that will burn slowly in any vessel or stove, or in the open air,
and at the same time yield an intense heat; the ingredients constituting the said
fuel and the method of producing the same being hereinafter clearly described and
set forth in the claims.
To carry my invention into effect, I take the following ingredients, which I term
"Sestalit," consisting of 95 lbs. of lime (calcined limestone) and 5 lbs. of gypsum, (or
plaster) and make a solution of the same in ten gallons of water.
I then dissolve in another vessel, two lbs. of acetate of lead in an additional five
gallons of water. When these two solutions are properly dissolved or mixed, I throw
them both together into one vessel and continue to stir the same until they are
thoroughly combined. I afterwards nix this combined solution with any suitable
carbonaceous substance until a thickened mass is produced.
In a suitably constructed apparatus, by preference of a cylindrical form, containing
agitators, or mixing arms, with a rotating shaft passing through it longitudinally,
place a sufficient quantity of powdered vegetable charcoal, coke, coal, or other car-
bonaceous substance to absorb the before mentioned fifteen gallon solution, and the
whole is then mixed together by rotary agitation in this cylindrically formed
apparatus until a thickened mass is produced, of about the consistency of stiff
mortar.
This being accomplished, I pass the agglomerated mass through compressing
rollers, or any other suitable machinery, or apparatus that will press the pasty
compound into blocks, cakes, or balls of any required shape, or size and either
perforated or otherwise.
These blocks or cakes are then dried, either in the open air or by exposure to heat,
in any kind of kiln or drying chamber, and are then ready for use, for either domestic,
commercial, or manufacturing purposes.
The solutions above referred to as "Sestalit" not only produce (when mixed with
carbonaceous substances) a safe, combustible fuel, but effect great cohesion, and bind
the whole block together, without destroying the necessary porosity of a compact and
perfect composition fuel.

page_text: 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 1
claim is
1. As a new article of manufacture, a compressed composite fuel, composed of a
powdered carbonaceous substance, or substances, saturated with a solution containing
acetate of lead, lime, and gypsum, substantially as described and for the purposes set
forth.
2. The combination of ingredients hereinbefore described, consisting of powdered
charcoal, or other carbonaceous substances, made into blocks after being saturated
with a solution containing acetate of lead, lime, and gypsum, in about the following
proportions, viz :-
One hundred pounds of carbonaceous substances.
Two pounds of acetate of lead.
Ninty-five pounds of lime.
Five pounds of gypsum.
All being prepared, mixed and compressed, for the purposes specified and in the
manner described.
