We, ISAAC FERNAND KAHN-VIOLLET and JOSEPH GASPARD Fox, of 11, Ruo
Monthyon, Paris, in the Republic of France, Manufacturers, do hereby declare the
nature of this invention to be as follows: :-
This invention relates to improvements in connection with furnaces and has for
its object to provide for the more perfect consumption of smoke than heretofore
the said improvements being applicable for use with every variety of furnace.
The principle of our invention consists essentially in heating the fuel whilst on
its way to the hearth and before its introduction to the same.
According to our invention the passage through which the fuel is conducted to the
hearth opens into a chamber in proximity to the hearth, and opening into the upper
part of the same. In front of the chamber the said passage is divided into two parts by
a horizontal partition. The space underneath the partition forms a passage of variable
width and serves for the introduction of a stoking iron whilst the part of the
passage above the partition serves for the introduction of the fuel into the hearth.
The fuel is fed into the chamber where it is subjected to a gradual increase of
temperature by reason of its contact with the hot gases of the hearth and with the
walls of the furnace. Distillation takes place, gases being given off and burnt on
their passage over the hearth. At the end of a certain interval of time (which is
variable but may be easily determined experimentally once and for all for each
kind of furnace and for all kinds of fuel) the fuel deprived in this manner of gas is
raked on to the grate of the hearth. A stoking iron is introduced, when required,
into the space under the partition so as to break and stir up the fuel during its
heating in the chamber for the purpose of permitting the heat to be easily
distributed throughout the whole mass and of allowing the gases generated to
escape with greater facility.

Improvements in connection with Furnaces.
We, ISAAC FERNAND KAHN-VIOLLET and JOSEPH GASPARD Fox, of 11, Rue
Monthyon, Paris, in the Republic of France, Manufacturers, 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 improvements in connection with that class of furnaces
which are provided with chambers for heating or coking the fuel before its
introduction into the grate and the invention consists in certain improvements in
the coking chamber as hereinafter more particularly described.
The accompanying drawing represents by way of example a vertical section of a
glass-furnace with our improvements applied thereto.
According to our invention the coking chamber b through which the fuol is
conducted to the grate opens into the upper part of the same, the front part of the
said chamber b being divided into two parts by a horizontal partition c.
The space
underneath the partition c forms a passage m of suitable width and serves for the
introduction of a stoking iron whilst the part of the chamber above the partition c
serves for the introduction of the fuel into the grate. The fuel is fed into the
chamber b where it is subjected to a gradual increase of temperature by reason
of its contact with the hot gases of the grate and with the walls of the furnace.
Distillation takes place, gases being given off and burnt on their passage over the
grate. At the end of a certain interval of time (which is variable but may be easily
determined experimentally once and for all for each kind of furnace and for all
kinds of fuel) the fuel deprived in this manner of gas is raked on to the bars g
of the grate.
A stoking iron is introduced, when required, into the space m under
the partition c so as to lift and stir up the fuel during its heating in the chamber b
for the purpose of permitting the heat to be easily distributed throughout
the whole mass and of allowing the gases generated to escape with greater
facility.
Having now particularly described and ascertained the nature of
our said
invention and in what manner the same is to be performed, we declare that we do
not claim generally a smokeless furnace in which the fuel preliminarily placed
and allowed to remain for a time in a passage arranged above the level of the
grate and is there subjected to a gradual increase of temperature by contact with
the gases from the fire and with the walls of the furnace so as to distil the gases
from the said fuel and allow of their being burnt as fast as they are given off, the.
fuel being raked into the bars of the grate only when it has been deprived of its
gases, but what we do claim is :-
1. A smokeless furnace of the kind described in the preceding paragraph having
a coking chamber opening into the upper part of the grate, and in which the fuel is
placed and allowed to remain for a time, the said coking chambers being divided
into two parts by a horizontal partition, the space underneath the partition serving
for the introduction of a stoking iron whilst the space above the partition
serves for the introduction of the fuel into the grate, substantially as hereinbefore
described.
2. The improved furnace herein before described and illustrated in the accompany-
ing drawing.
