Improvements in the Manufacture of Fuel and in Machinery or
Apparatus Used in Connection therewith.
I, ROBERT STONE, of 101 Leadenhall Street, in the City of London, Engineer, do
hereby declare the nature of my said invention to be as follows:-
I grind chalk or lime or lime stone or any other substance or material liable to
combustion to a powder. I then mix the powdered chalk, lime, or lime stone, or other
material, with tar, petroleum spirit, petroleum, oil of vitriol, or vitriol or creosote or
any other inflammable liquids. I sometimes mix a little breeze, or coal refuse or coal
dust, and compress the mixed materials into balls, blocks or brickets. When mixing
the aforesaid liquids with peat or any other fibrous material I prefer to add some of
the powdered chalk, lime or limo stone therewith, in order to make the fuel hard and
more durable in burning, or I may sometimes mix the liquids with coal refuse, breeze,
or any other combustible material. The introduction of vitriol intensifies the heat,
beyond that of the strongest coals. In some instances I mix the petroleum or other
inflammable liquids with the vitriol and burn the same as liquid fuel; and in some
cases I simply soak or saturate the aforesaid materials direct from the quarries or
peat lands, without grinding or compressing. The machinery used for grinding the
aforesaid fuel consists of rolls mounted on suitable axles, and geared together, so as to
rotate simultaneously. The peripheries of the rolls have annular grooves, semicircular,
rectangular, or otherwise, in section. The material is thereby pressed into corresponding
shapes, and may be cut in convenient lengths for use.
In some cases I use one grooved roll and one plain roll, in combination, for
imparting the necessary shape to the fuel, as it is rolled and pressed between the
same.
I also use an eccentrically mounted drum or cylinder, revolving eccentrically in
another cylinder, or portion of a cylinder; the latter having perforations of suitable
shapes, through which the fuel is pressed, and thereby caused to assume the necessary
sectional forms.

I, ROBERT STONE of 101 Leadenhall Street in the City of London, Engineer, do
hereby declare the nature of my said invention and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement, reference being had to the accompanying drawings
:-
I grind chalk or line or lime stone or any other like substance or material under
treatment to a powder. I then mix the powdered chalk, lime, or lime stone, or other
material, as aforesaid, with tar, petroleum spirit, petroleum, oil of vitriol, or vitriol, or
creosote in combination with other ordinary inflammable liquids in order to intensify
the heat. I sometimes mix a little breeze or coal refuse or coal dust, or peat and
compress the mixed materials into balls, blocks, or brickets. The introduction of
vitriol intensifies the heat beyond that of the strongest coals. In some instances I
mix the petroleum or other inflammable liquids with the vitriol and burn the same as
liquid fuel and in some cases I simply soak or saturate the aforesaid materials direct
from the Quarries or Peat lands, without grinding or compressing-The Proportions
of the several ingredients forming the mixtures are necessarily very much varied to
suit the character and analysis of the materials to be operated upon-But I find it
advantageous, in practice, in using Petroleum, tar or creosote without vitriol, to add
12 Gallons (more or less) to each ton of material. And, when using vitriol, without
petroleum, tar or creosote, I add a similar quantity, viz.:-12 Gallons of vitriol (more
or less) to each ton of materiál, in addition to any other fuel used in the process.
When using both liquids: Petroleum and vitriol, I add Gallons of each (more
or less).
The machinery used for grinding the aforesaid fuel consists of rolls mounted on
suitable axles, and geared together, so as to rotate simultaneously.
The peripheries of the rolls have annular grooves, semicircular rectangular, or
otherwise in section as shewn in Figs. 1. 2 and 3 of the drawings-The material
is thereby pressed into corresponding shapes, and inay be cut in convenient lengths
for use.
In some cases I use one groved roll and one plain roll, in combination for imparting
the necessary shape to the fuel, as it is rolled and pressed between the same.
I also use an eccentrically mounted drum or cylinder a Fig. 4 revolving eccen-
trically in another cylinder or portion of a cylinder 6 the latter having perforations ce
of suitable shapes, through which the fuel is pressed, and thereby caused to assume
the necessary sectional forms.

page_text: 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 :-
1. In the manufacture of fuel the several combinations of the respective substances
and fluids, substantially as herein before described.
2. The method of manufacturing fuel by mixing and grinding the several and
respective materials, together constituting my improvements in the manufacture of
fuel, and in machinery or apparatus used in connection therewith substantially as
hereinbefore described.
