Improvements in Incandescence Gas-burners.
I, AUGUSTE BESSON, of 15 Rue des Halles, Paris, France, do hereby declare
the nature of this invention to be as follows:-
In one arrangement of incandescence burner according to this invention, the
Bunsen burner employed is so constructed as to enable the amount of gas used to
be readily controlled, for which purpose the chimney of the Bunsen burner is
provided, at a certain distance from its base, with a diaphragm which may be of
conical form, through which a hole is made at its centre. In the lower part
of this chimney there is screwed a piece through which pass four holes, and
which is furnished at its centre with a small conical projection, which may be
either rigidly fixed in the said piece or be regulable therein, as regards height,
by screwing or other suitable means. At the base of the chimney there are two
ears, or a milled part, to enable the chimney to be more or less screwed on the
aforesaid piece so as to cause the said cone to enter the hole of the aforesaid
diaphragm to a greater or less extent in order thereby to increase or to diminish
the volume of gas passing through the aforesaid hole in the said diaphragm, and
thereby to regulate the intensity of the light, which can thus be reduced to that of
a night-light.
At the top of the chimney there is the combustion-chamber, in which there are
arranged a cone for deflecting the flame from the centre and towards the periphery,
and a sheet of metal, which may be folded in a wing-like form wound spirally, or
arranged in any other suitable manner for the purpose of increasing the heat of
the flame by recuperation, the mixture of gas and air being thus heated and a
greater calorific result thereby obtained.
On this chamber there is fixed a socket-piece for supporting a double rod from
which the mantle is suspended. This arrangement presents the great advantage
of considerably facilitating the putting on of the mautles and the removal
thereof.
For the regulation of the Bunsen burner there may be employed, in lieu of the
arrangement hereinbefore described, one in which there is substituted for the
diaphragm a small chimney which extends above the holes provided for the admission
of air.

I, AUGUSTE BESSON, of 15 Rue des Halles, Paris, France, 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:
This invention consists in improvements in incandescence gas-burners, which
I will proceed to explain with the aid of the accompanying drawings wherein.

Fig. 1 is a central vertical section of a gas buruer according to this invention,.
and
Fig. 2 is a cross section thereof.
Figs. 3 and 4 are central vertical sections illustrating modified arrangements.
In an incandescence burner according to this invention, the Bunsen burner
employed is so constructed as to enable the amount of gas used to be readily
controlled, for which purpose the chimney or tube A (Fig. 1) of the Bunsen burner,
is provided, at a certain distance from its base, with a diaphragm B, which may be
of conical form and through which a hole is made at its centre. In the lower part
of the chimney or tube A there is screwed a piece C formed with holes.c and
furnished at its centre with a small conical projection a, which may either be rigidly
fixed in the piece C, or be regulable therein, as regards height, by screwing (as
shown), or by other suitable means. At the base of the chimney or tube A there
are two ears b, or a milled part, to enable the chimney to be more or less screwed
on the piece C so as to cause the conical projection a to enter the hole in the
diaphragm B to a greater or less extent in order thereby to diminish or to increase
the volume of gas passing through the said diaphragm and thereby to regulate
the intensity of the light, which can thus be reduced to that of a night-light.
At the top of the chimney or tube A there is the combustion-chamber D, in
which there are arranged a cone E, for deflecting the mixture of air and combustible
gas from the centre towards the periphery, and a sheet of metal F, which may be
folded into a wing or star-like form as seen in plan (Fig. 2), or spirally, or arranged
in any other suitable manner for the purpose of increasing the heat of the flame
by recuperation, the mixture of gas and air in flowing over the said metal sheet,
which acts as a recuperator, being heated thereby so that a greater calorific result
is obtained. The recuperator may be cast, it may also be made as a perforated
cap (Fig. 1); or as a capsule of woven metallic wire. The said recuperator
carries the deflecting cone E and is placed in or on the combustion chamber in
such a manner that it can be easily removed therefrom when desired.
On the combustion chamber there is fixed a socket piece H provided with
eyes H¹ for supporting double rod I from which the mantle is suspended. This
arrangement presents the great advantage of considerably facilitating the putting
on of the mantles and the removal thereof. The socket piece H is arranged to fit
on and around the combustion chamber with slight friction.
For the regulation of the Bunsen burner there may be employed, in lieu of the
arrangement bereinbefore described, that represented in Fig. 3, in which there is
substituted for the diaphragm B a small chimney G, which extends above the
holes J provided for the admission of air.
The arrangement shown in Fig. 4 is similar to that shown in Fig. 1 with the
exception that the regulating-sleeve K of the Bunsen burner has attached to its
upper portion an annular casing L which serves both to aid in deflecting the air
into the chimney and also to prevent the entering air from causing the combustion
of the gas to take place at the bottom of the burner.
Having now particularly described and ascertained the nature of the said inver-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. An incandescence gas burner in which the burner chimney or tube is provided
with a diaphragm having a gas exit hole through it at its centre, or a small chimney,
and is arranged to be connected by screwing to a nozzle or part carrying a conical
projection, the arrangement being such that the delivery of gas can be controlled
by screwing the burner chimney or tube to or from the conical projection
substantially as herein described.
2. In an incandescence gas burner, the arrangement in the centre of a combustion
chamber at the top of the burner chimney or tube, and in the current of the gaseous
mixture flowing through said chamber of a cone adapted to deflect the gaseous
mixture towards the periphery of the chamber, and an upper screen or recuperator

page_text: adapted to compel the flame to heat the gaseous mixture flowing through the
combustion-chamber, substantially as herein described.
3. My improved incandescence gas-burner constructed and arranged as herein-
before described with reference to and shown in Figs. 1 and 2 or modified according:
to Fig. 3, or to Fig. 4 of the drawings annexed.
