PROVISIONAL SPECIFICATION.
Improvements in Means for Supplying and Regulating the Supply of
Air to Fire Grates and the like, adapted also for Fire Lighting
Purposes.
WILLIAM LACY CLARK, Contractor, Hessle, Hull, Yorks, do hereby declare the
nature of this invention to be as follows:-
Improvements in appliance for promoting incandescence of fuel, & regulating
the draft to fire grates furnaces and the like..
My invention relates to an appliance for promoting & regulating the admission
of air to the interior of fire grates furnaces, etc., with the object of increasing or
decreasing the incandescence in fires, & regulating the draft & consumption
of fuel.
acts as a
My invention which may be called an "incandescence generator," or
" air reser-
voir is made of metal, asbestos, fire clay or other fire resisting material,
& is of various shapes & sizes. The generator" may be semi-circular,
or other suitable section. i.e., as an inverted dish; the underside being concave
reservoir" for the air which is to pass through it into the fire, by
means of perforations, cones, or tubes, which are on the convex or outer side of the
reservoir, thus the oxygen is freely admitted into the heart of the fire increasing
the diffusion of heat & producing greater incandescence. The appliance may be
in a fixed, or moveable form, for the bottom, back, or other convenient part of the
fire grate. The "generator" may have indentations or depressions for holding
oils, liquids, pitch, etc., to facilitate the lighting of fires, I find by being able to
regulate the currents of air which pass through the "generator" into the fire is an
advantage, & for this purpose I introduce an air regulator" or ventilator"
which also economises fuel, to act in conjunction with the " generator" or
seperately; I prefer to make the "regulator" on the "louvre " or "damper"
principle by venetians, slides, or valves, made of metal or other suitable material
constructed in such a way, as to effectually regulate the supply of air. When the
regulator" is used with the "generator" they may be attached by hinges, pivots,
or other suitable means; but when the "regulator" is used seperately, I prefer to
fix it on a metal frame for fitting to the fire grate, in all cases I use a slide attach-
ment or other convenient means to open & close the "regulator," I prefer to make
the "generator" & "regulator" each in several parts for convenience.

WILLIAM LACY CLARK, Hessle, Hull, Inventor, 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:-
My invention relates to an appliance for promoting and regulating the admission
of air to the interior of fire grates, furnaces, and the like, with the object of
increasing or decreasing the incandescence in fires and regulating the. draft and
consumption of fuel.
My invention which may be called an incandescence generator or air reservoir,
is made of metal, asbestos, fire-clay, or other fire resisting materials, and is of
various shapes and sizes, the generator is semi-circular, or other suitable section,
i.c., as an inverted dish, the under side being concave, acts as a reservoir for the
air which is to pass through it into the fire by means of perforations, cones or
.tubes which are on the convex or outer side of the reservoir, thus the oxygen is
freely admitted into the heart of the fire and produces greater incandescence. The
appliance may be in a fixed or moveable form for the bottom, back, or any other
convenient part of the fire-grate. The generator may have indentations or depres-
sions for holding oil, liquids, pitch and the like, to facilitate the lighting of fires, I
find that by being able to regulate the currents of air which pass through the
reservoir into the fire is an advantage, and for this purpose I introduce an air
regulator or ventilator which also economises fuel, to act in conjunction with the
reservoir, or separately; I prefer to make the air regulator or ventilator on the
louvre or damper principle by means of slides, valves, or venetians, made of metal
or other suitable material, constructed and fitted in such a way as to effectually
regulate the supply of air.
When the air regulator is used with the air reservoir they may be attached by
hinges, pivots, or other convenient means, but when the air regulator is used.
separately I prefer to fix it on a metal frame for fitting to the fire-grate, in all cases
I use a slide attachment or other convenient means to open and close the regulator.
I prefer to make the reservoir and regulator each in several parts for convenience.

A, is a generator constructed of metal or any fire-resisting material, on the upper
surface of which are cones C, through which air passes into the fire, and indenta-
tions or depressions B, for holding oils or the like, to facilitate the lighting of
fires Figs. 1, 2, 3.
D), is an air regulator, constructed of metal, or other suitable material, having
louvres E, which are opened or closed by means of a sliding shaped bar F, working
in holders H, attached to D, and operated by projecting handle G, Figs. 4, 5.
This air regulator is used in conjunction with the generator, or separately.
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:-

page_text: 1.The incandescence generator substantially as described and illustrated in
Figs. 1, 2, 3, of accompanying drawings.
2. The air regulator substantially as described and illustrated in Figs. 4, 5 of
accompanying drawings.
3. The combination of incandescence generator and air regulator, substantially
as and for the purpose specified.
