page_text: I ARTHUR LODGE SIZER of 34 Kildon Road, Clapham Common, London, S. W.
Stone Mason, do hereby declare the nature of this invention to be as follows:-
The object of my invention is to provide a simple means whereby the combustion
may be controlled in Kitcheners and the like according to requirement, with a view
to effect a considerable economy in the consumption of fuel.
In accordance with my invention I provide a supplementary flue or flues placed in
any suitable position or positions at the back of a Kitchener or the like, into which
enlers a portion of the air supply, (the whole of which usually passes up through the
grate bars) and, by means of a suitable regulating damper the upward current may
be controlled, so that in proportion to the quantity of cold air entering the special
or supplementary flues which I provide as above, the temperature is modified and
consequently the intensity of the induced draught through the fuel, the rate of
combustion being reduced accordingly.
In addition to the supplementary flues above referred to, and if desired in combi-
nation therewith, I employ a ventilator placed in any convenient position on the back
plate of the Kitchener and communicating with the main flue. Said ventilator tends
to improve the action of the supplementary flue or flues aforesaid, and the ventilator
and supplementary flue or flues may be employed in combination with, or independently
of each other, according to requirements.

page_text: I, ARTHUR LODGE SIZER, of 34 Kildon Road, Clapham Common London S.W.
Stone-mason, 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 my invention is to provide a simple and efficient means whereby
the combustion may be controlled in kitcheners and the like, according to requirement,
with a view to effect a considerable economy in the consumption of fuel.
In order that my invention may be the better understood I have appended the
accompanying sheet of drawings in which Figure 1 represents a sectional clevational
view of a kitchener to which my improvements are adapted. Figures 2 and 3 are
elevational views of a supplementary flue according to my invention and Figure 4
is a detached view of a damper to be herein more particularly referred to.
In carrying out my invention I provide a supplementary flue or flues A placed in
any suitable position or positions at the back of a kitchener B or the like, into which
enters a portion of the air supply, (the whole of which usually passes up through the
grate bars) and, by means of a suitable regulating damper D Figures 2 and 3, the
upward current may be controlled, so that in proportion to the quantity of cold air
entering the special or supplementary flue A which 1 provide as above, the temperature
is modified, as also is the intensity of the induced draught through the fuel; the rate
of combustion being reduced accordingly.
The supplementary flue or flues A above referred to is or are made up preferably
of three parts a, a, a", the upper part a of which serves as a hood, and has a flange b
formed at its lower end, to allow of its fitting on to the upper extremity of the middle
portion aUpon the upper end of the middle portion a' aforesaid is formed on the
front and back thereon a semicircular slot into which take the extension pieces of
the damper C; one of which extension pieces passes through and beyond the back
plate D of the kitchener, terminating in a suitable knob or handle as shown at c.
The lower extremity of the middle part of the supplementary flue a terminates
in a short cylindrical tube d which, fitting over and embracing a smaller cylindrical
tube e formed upon the lower part a" of the supplementary flue or flues, and at right
angles thereto allows of the upper portions a, a' being turned so as to avoid interference
with the boiler and boiler pipes.
In addition to the supplementary flue or flues above described, and if desired, in
combination therewith, I employ a ventilator E, Figure 1, (shown also detached in
Figure 1) hinged in any convenient position to the back plate D of the kitchener B,
and communicating directly with the main flue. Upon said ventilator is pivoted a
rack forming the segment of a circle, and terminating exteriorily in a suitable knob
or handle to allow of the rack aforesaid being engaged or disengaged with the
lower edge of the aperture in the back plate D aforesaid. Said ventilator may, if
desired, be employed alone, the damper of the supplementary flue being closed-but,
when used in conjunction with the supplementary flue or flues it tends to increaso
the efficiency of the latter.

page_text: 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 :-
First
The improved slow combustion kitchener substantially as herein described
and illustrated in the accompanying drawings.
Second In combination with a kitchener and the like the adaptation thereto of a
supplementary flue or of supplementary flues substantially as and for the purposes
herein described and shown.
Third In the improved kitchener referred to above, the combination with a
supplementary flue or with supplementary flues, of a ventilator, substantially as herein
set forth and shown.
