IMPROVEMENTS IN THE MANUFACTURE OF ARTIFICIAL FUEL
Year: 1867

page_text: LETTERS PATENT to Henry Fletcher, of 39, Old Hall Street, Liverpool,
for the Invention of "IMPROVEMENTS IN THE MANUFACTURE OF ARTIFICIAL
FUEL."
Sealed the 10th December 1867, and dated the 11th June 1867.
PROVISIONAL SPECIFICATION left by the said Henry Fletcher at the
Office of the Commissioners of Patents, with his Petition, on the 11th
June 1867,
I, HENRY FLETCHER, of 39, Old Hall Street, Liverpool, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN THE MANUFACTURE OF
ARTIFICIAL FUEL," to be as follows:-
I manufacture the fuel from "slack" or small coal mixed with pitch or
other adhesive material. The coal may be made dry & hot before the pitch
or other adhesive material is added, and then the heated compound is ground,
granulated, or pulverized, and thoroughly admixed simultaneously in a suitable
machine such as "Carr's disintegrator," or other apparatus for so pulverizing
and mixing. The admixed material is then reheated to render it cohesive,
and afterwards it is put into suitable moulds and pressed in blocks; or the
coal may be used in a cold state and the pitch or other adhesive material
[Price 8d.]

page_text: added. This cold compound is ground, granulated, or pulverized and
thoroughly admixed simultaneously in a similar manner to that above
mentioned with the heated compound. This cold admixed material when
pitch is used is then passed through one or more heaters, and when rendered
thoroughly cohesive it is pressed into blocks. The adhesive material employed
may be some solution, as of silica, farina, or other substance not requiring
heat.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry Fletcher in the Great Seal Patent Office on the
11th December 1867.

NOW KNOW YE, that I, the said Henry Fletcher, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-

statement thereof (that is to say) :-
I manufacture this improved artificial fuel from "slack" or small coal mixed
with pitch or other adhesive material. The coal may be made dry and hot

page_text: before the pitch or other adhesive material is added, and the heated compound
is ground, granulated, or pulverized and thoroughly admixed simultaneously
in a suitable machine such as "Carr's disintegrator," or other apparatus for
so pulverizing and mixing. The admixed material is then reheated to render
it cohesive, and afterwards it is put into moulds and pressed into blocks; or
the coal may be used in a cold state and the pitch or other adhesive material
added. This cold compound is ground, granulated, or pulverized and
thoroughly admixed simultaneously in a similar manner to that above
mentioned with the heated compound. This cold admixed material when
pitch is used is then passed through one or more heaters, and when rendered
thoroughly cohesive itis pressed into blocks. The adhesive material employed
may be some solution, as of silica, farina, or other substance not requiring
heat.
In witness whereof, I, the said Henry Fletcher, have hereunto set my
