Year: 1876

page_text: LETTERS PATENT to Felix John Hamel, of 70, Avenue Road, Regent's Park, in
the County of Middlesex, for the Invention of "IMPROVEMENTS IN THE MANU-
FACTURE OF ARTIFICIAL FUEL."
Sealed the 20th June 1876, and dated the 1st January 1876
PROVISIONAL SPECIFICATION left by the said Felix John Hamel at the
Office of the Commissioners of Patents, on the 1st January 1876.
FELIX JOHN HAMEL, of 70, Avenue Road, Regent's Park, in the County of
Middlesex. "IMPROVEMENTS IN THE MANUFACTURE OF ARTIFICIAL FUEL"
This Invention has for its object improvements in the manufacture of artificial
fuel.
In order to produce artificial coal, peat, or any other kind of fuel, I employ china
clay reduced to a powdered state with mineral and vegetable pitch, and use them
in combination with resinous and fatty and oily matters, the whole being heated or
melted until they are of a consistency that enables them to be mixed with the coal,
peat, or other substances suitable for fuel, in a pug mill or travelling screw, and as
they travel or are in motion I use superheated steam to assist in the full amalgama-
tion of all the ingredients; the whole matter is then placed in presses for suitable
compression, similar to those explained and patented by me in Patent No. 1392,
dated the 7 day of May 1872, and sealed the 16 day of July 1872, or any other
kind of press adapted for the purpose.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Felix John Hamel in the Great Seal Patent Office on the 26th June
1876.
FELIX JOHN HAMEL, of 70, Avenue Road, Regent's Park, in the County of
Middlesex. "IMPROVEMENTS IN THE MANUFACTURE OF ARTIFICIAL FUEL."
This Invention has for its object improvements in the manufacture of artificial
fuel from small or dust coal, peat, or other substances suitable for fuel.
And in order that my said Invention may be well understood, I will now

page_text: proceed to describe the process I adopt for the manufacture of the said improved
artificial fuel.
In the first place I take what is known as china clay, and after bringing it to a
dry state I reduce it to a powder, and I either introduce it into the coal dust or
other substances before or after I have prepared a solution of mineral or vegetable
pitch combined with resinous and fatty and oily matters, the whole being then
agglomerated together they are further mixed by the use of a pug mill or travelling
screw, and as they travel or are in motion I apply jets of superheated steam to
assist in the full amalgamation of all the ingredients.
Secondly. I place the aforesaid prepared materials in presses for solidification;
for this purpose mechanical presses of various construction may be used, but I
prefer to use presses invented by myself and explained and patented by me in
Patent No.. 1392, dated the 7th day of May 1872, and sealed the 16th day of July
1872.
Having thus described the nature of my said Invention and the manner in which
the same is to be carried into effect, I wish it to be understood I do not confine
myself to any precise details or any specific quantities of the various materials I use
in my Invention, as such may be varied according to the description of coal or
other substances required to be manufactured into artificial fuel; I wish it to be
understood that what I claim and desire to secure by the herein-before in part
recited Letters Patent is, the manufacture of an improved artificial fuel by the use
of china clay in a powdered state with mineral and vegetable pitch or either of
them, and use them in combination with rosin or resinous and fatty and oily
matters, such materials being further assisted to combine by aid of superheated
steam.
In witness whereof, I, the said Felix John Hamel, have hereunto set my hand
and seal, this Ninth day of June, in the year of our Lord One thousand
nicht hunandand soment
