Improved Means for Consuming Gases and Effecting the Combustion
of Smoke in Furnaces.
I WILLIAM EBERHARD SANDER of Botolph House, Eastcheap in the County
of London, Gentleman 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 improved means for consuming gases and effecting the
combustion of smoke in furnaces.
My invention consists of a novel shaped hollow box wide at bottom and narrow
at top the front being curved the back and sides run straight from the bottom.
The said box has hollow arms or arches at its two sides.
The box and arches have openings at the top and sides to supply heated air to
the inside of the furnace thereby causing complete combustion.
I fit inside the box and arches plates coated with platinum or copper plate or
wires where required to assist the conversion of the gases.
The box and arches to be made of cast metal or other suitable material capable
of withstanding the heat in the furnace.
The aforesaid box is supported on iron bars at bottom end of the fire bars either
in front or at the back or in place of the ordinary fire bridge I provide shutters or
regulators at the bottom of box to regulate the admission of heated air.
And in order that my said invention may be fully understood I will now describe
the same with reference to the accompanying sheet of drawings which shews my
invention applied to an internal flue boiler, Fig. 1 being a transverse section and
Fig. 2 a longitudinal section. Fig. 3 section through line A. B. Fig. 2.
a shews hollow box with curved front a' this box rests on bars b b, c c¹ shew
openings in the box a the holes c are for the entrance of the partially heated air
and the holes c¹ for the exit of the highly heated air which commingles with the
gases and passes over the box a and by reason of the curved front a of the box a
the flames are directed over the said box so that the heated air may thoroughly
mix therewith which is not the case when the front of the box is not curved.
shews the fire bars, in addition to the box a. I employ hollow arms or arches d. d.
communicating therewith so that the heated air may be carried to the top of furnace
in order to commingle with the gases that might escape the current of air from the
top opening of box a. e is an air regulator or damper actuated by the rod f
from the outside of boiler. h (Fig. 3) shews copper plates or plates coated with
platinum to assist the conversion of the gases and i (Fig. 1) shews wires in the
arches d d for the same purpose.

I would remark in conclusion that I am aware of hollow boxes or bridges having
been hitherto employed but of different form.
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.
1. The construction and employment of a hollow box or bridge having a curved
front substantially as set forth.
2. The combination with a hollow box or bridge as described of hollow arms
or arches running from its sides towards the top of furnace substantially as
Bet forth

page_text: 3. The platinum or copper plates or wires in combination with a hollow box and
arms or arches substantially as set forth.
4. The improved means for consuming gases and effecting the combustion of
smoke in furnaces substantially as set forth.
