PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Artificial Fuel.
I, RUDOLF SCHIMPER, a Citizen of the United States of America, of Jersey
City, County of Hudson, State of New Jersey, do hereby declare the nature of
this invention to be as follows:-
My invention relates to an improved fuel composition which is mixed and
compressed into lumps, blocks or cakes and dried and subsequently used as a
substitute for coal or other heating agents for domestic or other purposes, the
composition having the quality of burning slowly and continuously in a flueless
stove or other vessel, without flame, smoke or obnoxious gases, smells or vapor,
and at the same time emitting an intense and uniform heat of a healthful nature.
The invention consists of a fuel composition which is composed of pulverized
charcoal, coal or coke and starch saltpetre and brown sandstone.
The method of compounding the ingredients is preferably as follows:-One
hundred pounds of pulverized charcoal or coal are mixed with three pounds and a
half of saltpetre, three pounds of starch, which is made in a thin paste by additional
water, and one half of a pound of powdered brown sandstone. These ingredients
are mixed with water in a sufficient quantity to produce a plastic composition, the
starch imparting the proper degree of adhesion to the means when the same has
been compressed into moulds, while the saltpetre supplies the necessary oxygen to
produce perfect combustion leaving but about five percentum of ashes.
The brown sandstone serves to absorb and neutralise any smell that the starch
may produce and also to some extent for retarding the too quick burning of the
composition, the same being added in a somewhat larger quantity when used with
coal or coke, while a smaller quantity is required when charcoal is employed. The
mass after being thoroughly mixed is run or mixed into moulds and compressed into
blocks, lumps or cakes of the desired size. The lumps or cakes are then dried
either in the open air or by a gentle heat until the water is entirely evaporated
therefrom.
The lumps or cakes burn with a very slight draught and without smoke, smell,
noxious gases or flame, and emit very great volume of wholesome heat. The fitel
produced by the above mentioned admixtures, can be easily ignited, and then
continues to burn slowly until totally consumed so that it is well adapted to be
used in heating and cooking stoves, car heaters, sad-irons, plumber's furnaces,
foot-warmers and for other purposes.

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 :-

Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is -
First. The herein described fuel composition consisting of pulverized charcoal
or coke, starch, saltpetre and brownstone, substantially in the proportions specified
and in the manner described.
Second. The herein described fuel composition for heating and cooking purposes,
consisting of charcoal, coke or other suitable carbonaceous substances and starch,
saltpetre and brownstone, all being properly moistened, mixed and compressed into
suitably shaped cakes or blocks in practically the following proportions, viz. :-
One hundred pounds of charcoal, three pounds of starch, three and a half pounds
of saltpetre and half pound of brownstone substantially as set forth and described
and for the purposes specified.
