page_text: to be performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say:-
This Invention has for its object improvements in the manufacture of
artificial fuel. For this purpose I employ a mixture consisting of coal or
other carbonaceous matter in a crushed or powdered state, clay or similar
tenaceous earthy material to cement together the other materials of the fuel,
and sawdust or other similar porous material capable of absorbing the chemical
solutions which I employ, and which are solutions of chloride of sodium or
other soluble chloride and nitrate of potash or other nitrate or other alkaline
preparation capable of supporting combustion.
The following proportions are suitable :-
Coal dust
Clay
Sawdust
Chloride of sodium
Nitrate of potash
- 16 cwt.
-
S"
"
2 lbs.
- 2 lbs.
Water sufficient to form a pasty mass.
The ingredients when thoroughly mixed are moulded by heavy pressure into
any desirable shape for burning. The salts should be first dissolved in water
and the solution absorbed with the sawdust, and the sawdust so prepared is
mixed with the other materials. The mixing may conveniently be effected in
a pug mill, and for moulding the materials brick-making machinery may be
employed. The moulded blocks are stacked in any convenient place and
allowed to dry in the air; they are then ready for the market.
In witness whereof, I, the said George Edward Allshorn, have hereunto
set my hand and seal, this Twenty-fourth day of June, in the year of
our Lord One thousand eight hundred and sixty-eight.
