I, WILLIAM BLACK of Stanrigg Airdrie in the County of Lanark, Coal Master,
do hereby declare the nature of my said Invention for "IMPROVEMENTS IN THE
MANUFACTURE OF BRIQUETTES OR FUEL BLOCKS" to be as follows:-
The object of my invention is to produce briquettes or fuel blocks which may
not only be available for steam raising and household purposes and for coke
making, but which may be specially applicable for use in lieu of cannel or gas coal
in the manufacture of illuminating gas. To that end I form briquettes or fuel
blocks by mixing with pulverised coal dross, or with peat or similar carbonaceous
material, pitch obtained in distilling shale oil, and compressing the mixture into
blocks by the use of machinery of the kind commonly employed in producing fuel
blocks in which coal tar pitch and coal dross are combined. In some cases I employ
shale oil pitch alone, as the material to be added to the pulverised coal dross or
other ordinary ingredients of fuel blocks in which case the blocks produced are
suitable for steam raising and for household use; but in other cases I prefer to make
use of the bye products left in the distillation of mineral oils or any product left
in the manufacture of illuminating gas or of shale oil, such as naphthaline, either
alone or in combination with shale oil pitch, or any similar bye product of dis-
tillation, in order to produce fuel blocks which when subjected to distillation
will yield illuminating gas. In making fuel blocks in which naphthaline or any
similar solid or crystalline substance forms an ingredient, the mixture may be
slightly heated, in order to liquify such ingredient, before or during the operation
of compressing.

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:-
The object of my invention is to produce briquettes or fuel blocks which may not
only be available for steam raising and household purposes and for coke making but
which may be specially applicable for use in lieu of cannel or gas coal in the manu-
facture of illuminating gas. To that end I forin briquettes or fuel blocks by mixing
with pulverised coal dross, cannel coal dross, shale, peat or similar carbonaceous
material pitch obtained in distilling shale oil, and compressing the mixture into
blocks by the use of machinery of the kind commonly employed in producing fuel
blocks in which coal tar pitch and coal dross are combined. In some cases I employ
shale oil pitch alone, as the material to be added to the pulverised coal dross or
other ordinary ingredients of fuel blocks, in which case the blocks produced are
suitable for steam raising and for household use; but in other cases I make use of
the hydrocarbon bye products left in the distillation of mineral oils or any product
left in the manufacture of illuminating gas or of shale oil, such as naphthalene,
naphtha, gasoline, benzol or benzene either alone or in combination with shale oil
pitch or any similar bye product of distillation in order to produce fuel blocks
which, when subjected to retorting or distillation will yield illuminating gas and
coke. In making fuel blocks in which naphthalene or any similar solid or crystal-
line substance, being a bye product of distillation, forms an ingredient the mixture
may be slightly heated in order to expel water and to liquify such ingredient before
or during the operation of compressing.
I find in practice that the class of coal which is best adapted to serve the objects
in view is that which contains a high percentage of moisture, and I find it
advantageous in using such coal to expel the moisture by the application of heat
or by other means and to grind the dross to a fine powder in order that it may
absorb a greater proportion of the hydrocarbon which is mixed with it in forming
the fuel blocks.
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. The manufacture of briquettes or fuel blocks for steam raising and house-
hold purposes from a mixture of pulverised coal dross, cannel coal dross, shale,
peat or other carbonaceous matter with shale oil pitch, substantially as herein
set forth.
2. The manufacture of briquettes or blocks for use in lieu of gas coal in the
production of illuminating gas from a mixture of pulverised coal dross, cannel coal

the distillation of mineral oils or in the manufacture of illuminating gas, sub-
stantially as herein set forth.
3. The manufacture of briquettes or blocks for use in lieu of gas coal in the
production of illuminating gas, by heating and compressing a mixture of pulverised
coal dross, cannel coal dross, shale, peat or other carbonaceous matter with solid
or crystalline hydrocarbons, such as naphthalene, obtained as bye products of
distillation, substantially as herein set forth.
