Improvements in the Manufacture of Artifloial Fuel or Briquettes.
I, ARTURO ZENDRONI, of 3, St. George's Avenue, in the City of London, Gentle-
man, do hereby declare the nature of this invention to be as follows:-
This invention relates to the manufacture of artificial fuel or briquettes from an
agglutinating substance of the kind described in the Specification of my former
Patent No. 2998 of 1896.
In my said former Specification the proportions of the ingredients forming the
compound given were those which produced briquette fuel of high calorific power
and which during combustion gives off no appreciable amount of smoke but the
proportion of calcium carbide is such that a low priced fuel cannot be produced.
I have found by experiment that a very good fuel can be produced and at a
relatively low cost by manufacturing the agglutinating substance in which the
proportions of the ingredients are substantially as follows:-
About 20 parts of pitch
2 parts of resin
1 part of naphthaline
2 parts of lime
27 parts of well ground anthracite or other coal and a proportion of
calcium carbide as hereinafter described.
In manufacturing the compound I employ the apparatus described in the
Specification of my said former patent the ingredients being treated in the manner
described in the said former Specification.
I find in practice that acetylene gas is produced by the action of the water in the
ingredients on the calcium carbide which gas fills the cylinder and is mixed and
combined with the ingredients.
As the quantity of acetylene gas generated from a given quantity of calcium
carbide is well known the proportion required to produce the best results can be
easily ascertained.
It will be obvious that the proportions of the ingredients above given may be
varied according to the quality of the fuel to be produced and that instead of coal I
may employ ground charcoal or coke.
.
In some cases the calcium carbide can be omitted the cylinder after receiving the
ingredients being then filled with ordinary coal gas. In this last case the gas
should be compressed to a pressure of about one and a half pounds to the square
inch before the heat is applied to the cylinder.
Dated this 26th day of June 1897.

I, ARTURO ZENDRONI, of 3, St. George's Avenue, in the City of London, Gentle-
man, do hereby declare the nature of this invention and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement :-
This invention relates to the manufacture of artificial fuel or briquettes from an
agglutinating substance of the kind described in the Specification of my former
Patent No. 2998 of 1896:
In my said former Specification the proportions of the ingredients forming the
compound given were those which produced briquette fuel of high calorific power
and which during combustion gives off no appreciable amount of smoke but the
'proportion of calcium carbide is such that a low priced fuel cannot be produced.
I have found by experiment that a very good fuel can be produced at a relatively
low cost by manufacturing the agglutinating substance in which the proportions of
the ingredients are substantially as follows:-
About 20 parts of pitch
2 parts of resin
1 part of naphthaline or any other suitable hydrocarburet of the same
family.
2 parts of lime
27 parts of well ground anthracite or other coal and a proportion of
calcium carbide as-hereinafter described.
In manufacturing the compound I employ the apparatus described in 'the'Specifi-
cation of my said former patent the ingredients 'being treated in the manner des-
cribed in the said former Specification.
I find in practice that acetylene gas is produced by the action of the water in the
ingredients on the calcium carbide which gas fills the cylinder and is mixed and
combined with the ingredients.
As the quantity of acetylene gas generated from a given quantity of calcium
carbide is well known the proportion required to produce the best results can be
easily ascertained.
It will be obvious that the proportions of the 'ingredients above given may be
varied according to the quality of the fuel to be produced and that instead of coal
I may employ ground charcoal or coke.
In some cases the calcium carbide can be omitted the cylinder after receiving the
ingredients being then filled with ordinary coal gas. In this last case the gas
should be compressed to a pressure of about one and a half pounds to the square
iuch before the heat is applied to the cylinder.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed; I declare that what I
claim is-
1. The manufacture of an agglutinating substance compounded and prepared,
substantially as herein before described.
2. Artificial fuel or briquettes manufactured 'from the agglutinating substance
herein before described.
