An Improvement relating to Firing Kilns for Burning Bricks,
Tiles, and other Goods.
I, HERBERT THOMAS SULLY, of 1, Queen Anne Buildings, Bristol, Electrical
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention which relates to firing kilns for burning bricks, tiles and other
goods, such as the coarser kinds of earthenware, consists in an appliance whereby
combustion of the substance used as fuel is promoted and made more perfect.
The fuel used may be pulverized coal, or coal sufficiently small as to pass readily
through the appliance. Or sawdust or other suitable substance or substances
may be used.

According to this invention, a hopper is placed in such of the usual fuel feeding
pipes or channels as may be desired and communicates at its lower end with a
delivery outlet. The hopper is preferably conical, the small end being at the
It is wider at the lower end than at the end
at which it connects with the hopper: The fuel fed into the hopper descends
therein and in passing through the delivery outlet the mass of fuel spreads. It is
accordingly more gradually, uniformly and economically consumed in the kiln.
To assist in the distribution of the fuel, a bar or bars may extend across the lower
end of the delivery outlet so as to break up the mass of descending fuel.
In salt glazing, salt, as is well understood, is mixed with the fuel and charged
therewith into the hopper, or it may be charged separately.
The appliance may be made of cast iron, steel, or of other suitable metal or
material. It is capable of being withdrawn at will from the fuel feeding tube
or channel.

1, HERBERT THOMAS SULLY, of 1, Queen Anne Buildings, Bristol, Electrical
Engineer, do hereby declare the nature of this invention and in what manuer the
same is to be performed, to be particularly described and ascertained in and
by the following statement:-
°
This invention which relates to firing kilns for burning bricks, tiles and other
goods, such as the coarser kind of earthenware, consists in an appliance whereby
combustion of the substance used as fuel is promoted and made more perfect.
The fuel used may be pulverized coal, or coal sufficiently small as to pass readily
through the appliance. Or sawdust. or other suitable substance or substances
may be used.
According to this invention, a hopper is placed in such of the usual fuel feeding
pipes or channels as may be desired, and communicates at its lower end with a
delivery outlet. The hopper is preferably conical, the smaller end being at the
bottom. The outlet is also conical. It is wider at the lower end than at the end
at which it connects with the hopper. The fuel fed into the hopper descends

accordingly more gradually, uniformly and economically consumed in the kiln.
To assist in the distribution of the fuel, a bar or bars may extend across the lower
end of the delivery outlet so as to break up the mass of descending fuel.
Referring to the accompanying sheet of drawings, Fig. 1 represents in elevation
the improved appliance in which this invention consists. In the section shown at
Fig. 2 the appliance, which may be of cast iron, steel, or other suitable metal or
material, represented as deposited in place in the usual channel in the crown of
a kiln for burning bricks, tiles and other goods.
The fuel, which may be pulverized coal, small coal, or sawdust or other usual sub-
stance, is charged into the mouth a of the appliance which is narrowed down to the
outlet 6 where the appliance increases in width to the delivery end.
The fuel fed into the hopper descends therein and is spread as it leaves the
outlet. To assist in spreading the fuel a bar c is extended across the lower end of
the outlet.
Across the upper end of the appliance is extended a bar d for connection with a
handle, chain, or rope, or other instrument, for withdrawing, when desired, the
appliance from the channel in which it is placed. e is the usual cover of the
said channel.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is
In a kiln for burning bricks, tiles and other goods, an appliance of cast iron,
steel or other suitable metal or material, for introduction into the usual firing
channels; the said appliance consisting of a conical receiver such as a having its.
greatest width at the top or fuel-receiving end, and opening into, at its lower or
narrowest end, a conical delivery outlet such as b the wider end of which is at the
bottom, substantially as hereinbefore described with reference to the accompanying
sheet of illustrative drawings.
