page_text: New or Improved Means for Promoting the Combustion of Smoke or
Inflammable Gases in Steam Boiler and other Furnaces.
I, HENRY WHITAKER of Anchor Hotel, Newent, Gloucestershire, Traveller, do
hereby declare the nature of my said invention to be as follows:-
My invention has for its object to provide simple and efficient means for enabling
the waste and unconsumed gases given off by a boiler fire to be mixed with heated
air drawn from the ash pit, and at such a point or points as will ensure of a complete
combustion of the said gases, instead of their being permitted to escape into the
boiler flue or chimney.
In carrying out my invention, I employ a number of metal plates, arranged in a
vertical position and at a space of about an inch from each other. Such plates are,
by preference, more or less of triangular form, and at their lower edge or base are
formed with a series of arched recesses, corresponding to the spacing of the fire-bars
of the furnace grate. The said plates are cast in one piece with the rear or hindmost
set of fire-bars, and at right angles or diagonally therewith, and in such position are
arranged immediately in front of the usual fire-bridge. These plates, so set, have a
toast-rack' appearance, and constitute' gills.'
With the heated fuel lying directly in front of such plates, and possibly at their
respective sides, they become highly heated and consequently, with the air from the
ash pit passing up the spaces between such plates, such air also becomes highly
heated, and issuing at the upper part of the plates and mingling with the smoke or
unconsumed gases affords a copious supply of oxygen, and thus ensures of the
complete combustion of such gases with the resulting advantages of increasing the
heating capacity of the boiler, and effecting an economy of fuel.
To facilitate the arrangement or fixing of the plates they may be formed in vertical
sections, and each section cast or formed in one with one or more fire bars, and for
the effectual joining of such sections together their abutting edges caused to over lap.

I HENRY WHITAKER of Anchor Hotel, Newent Gloucestershire Traveller, do hereby
declare the nature of my said invention and in what manner the same is to be
[Price 8d.1

page_text: performed, to be particularly described and ascertained in and by the following
statement:
My invention has for its objects to provide simple and efficient means for
enabling the waste aud unconsumed gases given off by a boiler fire to be mixed
with heated air drawn from the ash pit, and at such a point or points as will
ensure of a complete combustion of the said gases instead of their being permitted
to escape into the boiler flue or chimney.
On the accompanying drawing I shew a longitudinal section (Fig. 1) and a
transverse section (Fig. 2) of a Boiler furnace with my invention applied thereto.
(A) are the fire-bars, and loosely placed upon the rear set, or cast in one piece with
such bars (separately or collectively) is a set of plates (B), more or less of triangular
shape, and held by studs or rods about an inch away from each other.
These plates are, by preference, at right angles to the bars, and the lower edge of
each plate is arched or fluted, as shown in Fig. 2, opposite the spaces between the
'bars in order that the heat from the fuel, or air from the ash pit, may pass beneath
such plates.
With the heated fuel lying directly in front of such plates, and possibly at
their respective sides, they become highly heated, and consequently the air from
the ash pit passing up the spaces between such plates becomes highly heated,
and issuing at the upper part of the plates and mingling with the smoke or
unconsumed gases, affords a copious supply of oxygen, and thus ensures of the
complete combustion of such gases with the resulting advantage of increasing the
'heating capacity of the boiler, or effecting an economy of fuel.
To facilitate the arrangement or fixing of the plates they may be formed in vertical
sections and each section cast or formed in one with one or more fire-bars, and for the
effectual joining of such sections together their abutting edges may over lap, or the
plates may be held together by shoulders or parts interlocking when grouped together.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I claim is :-
or improved means for promoting the combustion of smoke or
inflammable gases in steam boiler and other furnaces substantially as described.
2. In means for promoting the combustion of smoke and inflammable gases, the
application and use of a number of plates arranged in a vertical position on, and
transversely with the fire bars, and operating substantially as described.
