PROVISIONAL SPECIFICATION.
An Improved Gas-burner for Heating and Lighting by Incandescence.
I, PAULIN NOËL, of 8, Rue Camille Desmoulins, Paris, in the Republic of
France, Mechanician, do hereby declare the nature of this invention to be as
follows:-
The burners heretofore employed for heating and lighting by incandescence,
present the disadvantage of operating very imperfectly when the supply of one
of the two elements, viz. :-gas and air, for which they are made, is modified, this
being due to the fact that the size of the chamber in which the mixture is made,
always remains the same.
The object of my invention is to obviate this disadvantage by varying the size
of the said chamber in accordance with the supply of air and gas.
In the accompanying drawing I have shown how my said invention may be
conveniently and advantageously carried into practice. In this drawing
Figure 1 is an elevation of my improved burner.
Figure 2 is a vertical central section thereof, the piston being in its lowermost
position.
Figure 3 shows the same burner in section, with the piston in its uppermost
position.
Like letters of reference indicate corresponding parts throughout the drawing.
As will be seen in this drawing, the cylindrical piece a, which forms the mixing
chamber of the burner, is made internally of two different diameters; the larger
part al is more particularly designed for the expansion of the gases and the
smaller al receives a piston b which serves to modify the capacity of the said
chamber.
A sleeve c is firmly connected to the chamber a by means of a ring d, forming
a nut, in which can be moved a screw-threaded stem e; this stem is made with
a quick thread and has the piston 6 secured to its upper end and the air-inlet or
lantern f to its lower end.
In the interior of the lantern, is the injector g for the supply of gas, the air
entering through the windows or apertures in the said lantern.
The piston being introduced into the part all of the chamber a and the stem e
engaging with the annular nut d, it will be seen that the more the section of the
air-inlet-orifices in the lantern f is diminished by the sleeve c, the more the piston b
will simultaneously diminish the capacity of the chamber a, and inversely. In
this manner, there will always be the same relation between the chamber a, and
the section of the air-inlet orifices, which is not the case in the burners hereto-
fore employed. In a word, with my improved burner, a single injector is suffi-
cient for both what is termed low pressure (from 15 millimetres to 50 millimetres)
or high pressure (50 millimetres and above).
At 50 millimetres, my injector delivers, for example, 260 litres, and at 15

An improved Gas-burner for Heating and ignting by Incandescence.
I, PAULIN NOËL, of 8, Rue Camille Desmoulins, Paris, in the Republic of
France, Mechanician, 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 burners heretofore employed for heating and lighting by incandescence,
present the disadvantage of operating very imperfectly when the supply of one
of the two elements, viz.:-gas and air, for which they are made, is modified, this
being due to the fact that the size of the chamber in which the mixture is made,
always remains. the same.
The object of my invention is to obviate this disadvantage by varying the size
of the said chamber in accordance with the supply of air and gas.
In the drawing accompanying my Provisional Specification I have shown how
my said invention may be conveniently and advantageously carried into practice.
In this drawing:
Figure 1 is an elevation of my improved burner.
Figure 2 is a vertical central section thereof, the piston being in its lowermost
position.
Figure 3 shows the same burner in section, with the piston in its uppermost
position.
Like letters of reference indicate corresponding parts throughout the drawing.
As will be seen in this drawing, the cylindrical piece a, which forms the mixing
chamber of the burner, is made internally of two different diameters; the larger
part a is more particularly designed for the expansion of the gases and the
smaller receives a piston b which serves to modify the capacity of the said
chamber.
A sleeve c is firmly connected to the chamber a by means of a ring d, forming
a nut, in which can be moved a screw-threaded stem e; this stem is made with
a quick thread and has the piston b secured to its upper end and the air-inlet or
lantern f to its lower end.
In the interior of the lantern, is the injector g for the supply of gas, the air
entering through the windows or apertures in the said lantern.
The piston b being introduced into the part all of the chamber a and the stem e
engaging with the annular nut d, it will be seen that the more the section of the
air-inlet-orifices in the lantern f is diminished by the sleeve c, the more the piston &
will simultaneously diminish the capacity of the chamber a, and inversely. In
this manner, there will always be the same relation between the chamber a, and
the section of the air-inlet orifices, which is not the case in the burners hereto-

page_text: fore employed. In a word, with my improved burner, a single injector is suffi-
cient for both what is termed low pressure (from 15 millimetres to 50 millimetres)
or high pressure (50 millimetres and above).
At 50 millimetres, my injector delivers, for example, 260 litres, and at 15
millimetres 150 litres, the capacity of the chamber a being diminished at the
same time that the supply of air is diminished. There are thus always three
things in constant relation to each other:-the supply of gas, the supply of air
and the capacity of the chamber.
When it is desired to apply my invention to a burner for lighting by incan-
descence, it is obvious that the chamber a can be provided with all the usual
accessories,, such as arrangements for supporting the mantle, etc.
The form, details, accessories, materials and dimensions of my improved burner
can obviously be modified without departing from the nature of my said invention.
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:-
An improved gas-burner for heating and lighting by incandescence, in which
the capacity of the mixing chamber can be varied and, at the same time, the open-
ing of the air-supply orifices regulated according to the pressure of the gas supplied,
this result being obtained by means of a chamber al having a portion in which
a piston forming part of a hollow stem e can be displaced, the said hollow stem
having air inlets f the cross-section of which is diminished, by their introduction
beneath a sleeve c, in proportion as the piston diminishes the capacity of the
chamber in which the expansion of the gas takes place, the gas passing into the
apparatus through an injector g placed at its lower part, substantially as described
and shown in the accompanying drawing.
