AUGUST LOHMANN, OF DALLAS, TEXAS, ASSIGNOR
H. FREEMAN, OF DALLAS, TEXAS.OF ONE-HALF TO
COMPOSITION OF MATTER FOR ARTIFICIAL FUEL.
SPECIFICATION forming part of Letters Patent No. 746,118, dated December 8, 1903.
Application filed October 19, 1903. Serial No. 177,706, (No specimens.).To all whom. it may -concern:
Be it known that I, AUGUST LOHMANN, a
citizen of the United States, residing at Dallas,
in the county of Dallas and State of Texas,
5 have invented a new and useful Composition
of Matter for Artificial Fuel, of which the fol-
lowing is a specification.
The basis of, my artificial fuel consists of
coals in which the change from woody fiber
to has not progressed as far as is found to be
the case in the harder coals. The kind of
coal which I find most useful for my purpose
is that known as "lignite." Other coals hav-
ing approximately thesame qualities as lig-
r5 nite are equally or nearly equally useful.
This coal is reduced to a powder, washed to
free it from impurities, and is then ready for
compounding. To cement this together into
coherent masses or briquets of suitable size,.
20 I mix it with a suitable binder and treat or
form it in any briqueting - machine of ap-
proved type after it has been heated and is
still warm. The basis of the binder which I
employ and its principal ingredient is a hy-
25 drocarbon which may be -extracted either
from the lignite or crude oil. In fact, any
heavy hydrocarbon sufficiently dense to be
solid at ordinary temperatures may be em-
ployed. To this hydrocarbon I find it useful.
30 to add others in small quantities, such as as-
phaltum and paraffin.
It is necessary to provide fuels of this kind
with some ingredient which will enable the
briquets to keep their form during ignition,
35 as otherwise the mass becomes soft and plas-
tic and runs together somewhat like ordinary
soft coal. This need I supply in the present
composition by the use of pulverized clay or
similar material, and preferably I employ the
40 kind of clay known as "kaolin," which is
nearly pure aluminium silicate. To this I
find it useful to add graphite, which seems to
unite with the clay to a certain extent and is
also useful in giving color and brilliancy tothe finished product. It also seems-to pre- 45
vent, to some extent at least, the abrasion or
disintegration of the briquets during han-
dling.
The formula given below is the one which
I prefer to use in the manufacture of my. 50
product; but it is to.be fully understood that
it is capable of variation as to the proportion,
number, and character of the ingredients.
Formula.--Lignite, eighty-nine per cent.;
hydrocarbon, eight per cent.; graphite, one 55
per cent.; kaolin, one per cent.; asphaltum,
one-half per cent.; paraffin, one-half per
cent. These proportions are by weight.
What I claim is-
1. An artificial fuel consisting of coal, a 6o
hydrocarbon, graphite, kaolin, asphaltum
and paraffin, substantially as- described.
2. An artificial fuel consisting of coal, a
hydrocarbon, graphite, clay, asphaltum and
paraffin, substantially as described. 65
3. An artificial fuel consisting of lignite, a
hydrocarbon, clay, and asphaltum, substa-n-
tially as described.
4. An artificial fuel consisting of lignite, a
hydrocarbon, clay, asphaltum and paraffin, 70
substantially as described.
5. An artificial fuel consisting of lignite, a
hydrocarbon, kaolin,asphaltum, and paraffin,
substantially as described.
6. An artificial fuel consisting of lignite, a 75
hydrocarbon, graphite, kaolin, asphaltum,
.and paraffin, substantially as described.
7. An artificial fuel consisting of the fol-
lowing ingredients, viz: lignite eighty-nine
per cent.; a hydrocarbon eight per cent.; 8o
graphite one per cent.; kaolin one per cent.;
asphaltum one-half per cent.; paraffin one-
half per cent., substantially as described.
