PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Fuel Briquettes or Blocks.
A communication from abroad by LA SOCIÉTÉ ANONYME DU COMBUSTIBLE INTENSIF,
of 23, Boulevard de Strasbourg, Paris, France.
I, JOHN CLAYTON MEWBURN of the Firm of J. C. Mewburn and Ellis of 55 and
56 Chancery Lane, London, Chartered Patent Agents, do hereby declare the nature
of this invention to be as follows:-
Coal briquettes and petroleum briquettes when used together have a higher calorific
power than the normal useful effect of these two materials considered, separately.
This is due to the more complete combustion of the carbon in presence of the
hydrocarbide and also to the more practical or rational utilization of the petroleum in
a medium maintained at constant temperature.
The addition of a large proportion of solidified petroleum to coal furnishes blocks
which are far from homogeneous and do not hold well together.
Now according to this invention I make coal briquettes of rectangular, cylindrical
or other suitable form with hollows or perforations constituting accessible cavities
of desirable size. Into these cavities I introduce solidified petroleum, either when
hot before complete solidification of the mass, or by compression when cold.
The result is the production of briquettes or blocks the filled cavities of which
act as small distillatory retorts charged with petroleum; these give off gaseous
hydrocarbide as the mass is heated whilst the incandescent coal maintains a constant
temperature which is very favourable to the combustion of the gases....
In this way the complete utilization of the two ingredients coal and petroleumi
is effected.

I, JOHN CLAYTON MEWBURN of the Firm of J. C. Mewburn and Ellis of 55 and

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:-

the hydrocarbon and also to the more practical or rational utilization of the petroleum

Having now particularly described and ascertained the nature of this invention
as communicated to me and in what manner the same is to be perforined, 1 declare
that what I claim is:-
1. The heréindescribed method of manufacture of composite fuel briquettes or
blocks, consisting in forming coal briquettes or blocks with suitable perforations
or cavities and then introducing completely or partially solidified petroleum into
said perforations or cavities.
2. As a new article of manufacture, a composite fuel briquette or block con
sisting of a coal briquette or block formed with perforations or cavities filled with
solidified petroleum.
