Year: 1879

page_text: LETTERS PATENT to William Lloyd Wise, of Chandos Chambers, Adelphi, in
the County of Middlesex, for the Invention of "A NEW OR IMPROVED
METHOD OR PROCESS OF MANUFACTURING AGGLOMERATED FUEL FROM COAL
DUST OR SLACK." A communication from abroad by Charles Hilt, of
Kohlscheid, in the Empire of Germany, Mining Engineer, and Manager of the
United Wurm Coal Mines, near Aix la Chapelle.
Sealed the 29th July 1879, and dated the 3rd February 1879.
PROVISIONAL SPECIFICATION left by the said William Lloyd Wise at the
Office of the Commissioners of Patents on the 3rd February 1879.
WILLIAM LLOYD WISE, of Chandos Chambers, Adelphi, in the County of
Middlesex. "A NEW OR IMPROVED METHOD OR PROCESS OF MANUFACTURING
AGGLOMERATED FUEL FROM COAL DUST OR SLACK." (A communication from
abroad by Charles Hilt, of Kohlscheid, in the Empire of Germany, Mining Engineer,
and Manager of the United Wurm Coal Mines, near Aix la Chapelle.)
This Invention relates to a new or improved method or process of manufacturing
agglomerated fuel from coal. The manufacture of good patent or artificial fuel,
bricks, or blocks from slack or pulverized coal depends very much upon the
cementing or binding material used. Of all the materials hitherto tried for this
purpose, coal tar or black pitch has given the most satisfactory results from a
technical and commercial point of view. The use of coal tar or black pitch is
however attended with disadvantages which have in many cases led to its being
abandoned and other fuel used in its place.
'
This Invention consists in using paper pulp as the cementing or binding material
for agglomerated fuel made from coa!, and numerous experiments have proved its
efficacy. The paper pulp or stuff, which may be of any suitable kind, may be used
in the same state of preparation as for making paper, though it is obvious it need
not be bleached.
In the manufacture of fuel according to this Invention the said paper pulp or
stuff is mixed with slack coal or coal dust in the proportion of from one to ten
pounds of paper pulp for every hundred pounds by weight of coal, more or less,
according to the quality of the fuel to be produced and the nature of the materials
used.

page_text: The mixture of coal and paper pulp is then placed in a pug mill or other suitable
machine into which vapour of water or superheated steam is admitted, and it is
there worked up. It is then compressed by means of any well known machinery
suitable for the purpose.
The paper pulp or stuff used for the purposes of this Invention may be made from
rags or any of their numerous substitutes, or from wood, straw, or other suitable
vegetable substance.
--Pulp-made from wood is very suitable for the purposes of this Invention, as
such pulp, besides being of itself an excellent fuel, is easily obtainable at a trifling
cost.

WILLIAM LLOYD WISE, late of Chandos Chambers, Adelphi, in the County of

Having now described the nature of the said Invention, and the manner of per-

The improved manufacture of agglomerated fuel from coal dust or slack combined
with paper pulp or stuff, substantially as hereinabove described.
In witness whereof, I, the said William Lloyd Wise, have hereunto set my
hand and seal, this Thirty first day of July, in the year of our Lord One
thousand eight hundred and seventy nine.
