We, ALFRED STANDING of No. 6 Southwark Bridge Road in the County of
Surrey Engineering Draughtsman, JOHN THOMAS SEARLE of 144 High Street
Kingsland in the County of Middlesex, Gentleman and HARRY WATTS of
Knapton House 30 Clissold Road Clissold Park in the County of Middlesex,
Gentleman do hereby declare the nature of this invention to be as follows:-
:
The object of our invention is the perfect combustion of smoke and carbon.
oxides &c. in boiler and other furnaces, and for the purpose of our invention we
place one or more air channels in the furnace in such manner and position as will
permit air to enter the space above the fuel direct from the ash-pit and mingle
with the unconsumed gases &c. and thereby effect their complete combustion.
Our apparatus is constructed of iron, steel, fire-clay or plumbago or any suit-
able combination of these or similar fire-resisting materials and is fitted with
valves for regulating the volume of air passing through.

COMPLETE SPECIFICATION.
Improvements in Smoke Consuming Devices.
We, ALFRED STANDING of No. 6 Southwark Bridge Road, in the County of
Surrey, Engineering Draughtsman, JOHN THOMAS SEARLE of 144 High Street,
Kingsland in the County of Middlesex Gentleman and HARRY WATTS of Knapton
House, 30 Clissold Road, Clissold Park in the County of Middlesex 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:―
The object of our invention is the perfect combustion of smoke and carbon
oxides &c. in boiler or other furnaces, and for the purpose of our invention we
place one or more air-channels in the furnace in such manner and position as will
permit air to enter the space above the fuel direct from the ash-pit and mingle
with the unconsumed gases &c., and thereby effect their complete combustion.
Our apparatus is constructed of iron, steel, fireclay or plumbago or any suitable
combination of these or similar fire-resisting materials and is fitted with valves for
regulating the volume of air passing through.
In constructing the air channels we make the vertical cross section of such a
shape as will induce the gases to enter them automatically by making the top part
more or less like an inverted funnel, or on the other hand by placing a baffler at
the top immediately over the opening so as to disperse the heated air among the
gases at their most inflammable point and also furnish them at a level nearer the
fuel with supplementary openings in order to facilitate the combustion of the gases
at an earlier stage.
For the purpose of vertical boilers we prefer to construct the air channels of an
oval or circular horizontal section and form the outer part of a series of half

page_text: rings each having a concentric projection on the top surface and a corresponding
recess on the bottom, this for the purpose of facilitating erection or renewal.
Fig. 1 on drawing herewith shews a vertical cross section of apparatus.
Fig. 2 is a longitudinal vertical section of furnace in a horizontal boiler.
Fig. 3 is a vertical section of apparatus as adapted to a vertical boiler.
A, A, in Figs. 1 & 2 shew the air-channels in cross & longitudinal vertical
section with the supplementary openings which may be oval, circular, oblong or
square in aperture.
C, C, C, shew the regulating valve in the lower part of iron seating or air
channel in each case; i shews the handle of the valve-rod in Fig. 2, which is
carried at the dead plate end by means of a hanging bracket bolted to front lip
of dead plate or furnace front. E, E, is the ordinary bridge of the boiler.
Figures O, R, S, U, V, W, shew several cross sections of air channels,
M, M, M, being the caps of the same.
We do not confine ourselves to the exact proportions of the various parts as
shewn, as it may be necessary to vary them to suit the varying shapes and
proportions of different boilers.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what
we claim is
1st. The air-channel A, A, Figs. 1 & 2 with each and all its associated details
in conjunction substantially as shewn and described for horizontal boilers.
2nd. The air-channel Fig. 3 with each and all its associated parts in conjunction
substantially and as shewn and described.
3rd. Air channels O, R, S, U, V, & W, with each and all their separate parts in
conjunction substantially as shewn and described.
