IMPROVEMENTS IN THE. COMPOSITION AND MANUFACTURE OF ARTIFICIAL FUEL BLOCKS
Year: 1876

page_text: LETTERS PATENT to Christopher Kingsford, of No. 292, King's Road, Chelsea,
in the County of Middlesex, for the Invention of "IMPROVEMENTS IN THE.
COMPOSITION AND MANUFACTURE OF ARTIFICIAL FUEL BLOCKS."
Sealed the 12th April 1876, and dated the 8th February 1876.
PROVISIONAL SPECIFICATION left by the said Christopher Kingsford at the
Office of the Commissioners of Patents on the Sth February 1876.
CHRISTOPHER KINGSFORD, of No. 292, King's Road, Chelsea, in the County of
Middlesex. "IMPROVEMENTS IN THE COMPOSITION AND MANUFACTURE OF ARTIFICIAL
FUEL BLOCKS."
My Invention relates to a composition and process for manufacturing artificial fuel
by agglomerating into blocks small coal, slack, coal dust, or other suitable car-
bonaceous materials in a small or divided condition.
I compound the carbonaceous material with bituminous matter and silicate of
soda, using about the following proportions:-To 100 parts by weight of the car-
bonaceous material I add about 5 parts of bituminous matter, preferably in the
form of ground pitch, and about 3 parts of solution of silicate of soda, preferably
of the specific gravity of 1.375.
In mixing these ingredients the method I prefer to adopt is as follows:-I place
the fuel and ground pitch in a suitable pug mill or mechanical mixer of any known
construction, and agitate or stir them well up together whilst they are heated
sufficiently to fuse the pitch, for which purpose I prefer to blow a current of super-
heated steam through the mass; I then add the solution of silicate of soda, by
preference warm, continuing the mixing action until the whole is thoroughly com-
pounded, I then immedately mould the compound into blocks under considerable
pressure by any known machine suitable for that purpose.
For convenience of grinding the pitch I prefer to grind it along with a portion
of the carbonacious material that is to be treated.

My Invention relates to a composition and process for manufacturing artificial
fuel by agglomerating into blocks small coal, slack, coal dust, or other suitable car-
bonaceous materials in a small or divided condition.
I compound the carbonaceous material with bituminous matter and silicate of
soda, using about the following proportions:-To 100 parts by weight of the car-
bonaceous material I add about 5 parts of bituminous matter preferably in the
form of ground pitch, and about 3 parts of solution of silicate of soda, preferably of
the specific gravity of 1375.
In mixing these ingredients the method I prefer to adopt is as follows:-I place
the fuel and ground pitch in a suitable pug mill or mechanical mixer of any known
construction, and agitate or stir them well up together, whilst they are heated
sufficiently to fuse the pitch, for which purpose I prefer to blow a current of super-
heated steam through the mass; I then add the solution of silicate of soda, by
preference warm, continuing the mixing action until the whole is throughly com-
pounded; I then immediately mould the compound into blocks under considerable
pressure by any known machine suitable for that purpose.
For convenience of grinding the pitch I prefer to grind it along with a portion
of the carbonaceous material that is to be treated.
Having thus described the nature of my Invention and in what manner the
same is to be performed, I claim, the manufacture of artificial fuel blocks by com-
pounding carbonaceous matter in a small or divided condition with bituininous
inatter and silicate of soda, and moulding the compound into blocks, substantially
as herein described.
In witness whereof, I, the said Christopher Kingsford, have hereunto set my
hand and seal, this Fourth day of August, in the year of our Lord One thousand
eight hundred and seventy-six.
C. KINGSFORD. (L.S.)
