Improvement in or relating to Acetylene Gas Burners.
I, CAESAR KAESTNER, of 17, Heinrichstrasse, Halle-on-Saale, Germany, Manu-
facturer, do hereby declare the nature of this invention to be as follows:
: -
The present invention concerns a capsule by the aid of which the flame of
acetylene gas is supplied with the necessary quantity of air, so that the flame in
Manchester burners, Bray's and the like cannot produce soot when the pressure
is either too strong or too weak, all the particles being absorbed by the flame.
All burners, known up to the present, employed for acetylene gas have the incon-
venience of constantly smoking when the pressure is either too high or too low,
or that the holes in the burners are so small that they, themselves, obstruct the
combustion.
The burners which give the best result are those with two holes, but they also
smoke when the pressure is not exactly determinated. All the particles are not
burnt in these burners either, when the pressure is too strong or too weak.
By the present invention which consists of a capsule with a groove and lateral
air-admissions the flame receives, without preventing its combustion, a small
pressure and the air current which is absolutely necessary to burn the particles.
No smoke is ever produced whether the pressure increases or decreases, and,
with a pressure that can be regulated, the flame burns with the clearest and whitest
brightness.
The capsule is constituted by a little socket fitted upon the upper extremity of the
burner. The periphery of this socket is provided with two apertures situated at
the level of the head of the burner where the flame begins which latter passes
through a slit formed by the bending inside, at right angle, of the upper part of
the socket.

I, CAESAR KAESTNER, of 17, Heinrichstrasse, Halle-on-Saale, Germany, Mann-
facturer, 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 present invention is connected with burners for acetylene gas and its special
בל

page_text: aim is to provide a metal capsule placed on the burner to regulate automatically
the admission of air in proportion to the pressure of the gas so as to secure com-
plete combustion of the latter, whether pressure increases or diminishes.
All the burners used up to the present, the Manchester system, Bray's and the
like, have the disadvantage of producing smoke when the pressure is increased
or diminished because the supply of air is either too little or too great.
In the first case the combustion is incomplete, and in the second, the heat of the
flame is lessened; the result in both cases is that all the molecules of carbon are
not burned and escape in smoke, which has not only the disadvantage of reducing
the lighting power of the flame but which also obstructs the openings through
which the gas flows.
This disadvantage is obviated by putting upon the burners a metallic capsule
for regulating the admission of the air automatically and proportionally to the
pressure of the gas.

In the annexed drawing is represented an example of the working of this cap-
sule as applied to an ordinary burner with two orifices.
Fig. 1 is a view in elevation of the burner and the capsule showing the admis-
sion holes.
Fig. 2 is another view in elevation looked at right angle of Fig. 1.
Figs. 3 and 4 are top views.
This capsule is composed of a cylindrical part A furnished on its upper part
with a small internal shoulder a and having two extensions or circular cheeks B
extending upwards, which cheeks are separated by a free space c serving to dis-
engage the Hame, and which space is bounded by the upper curved parts c¹ of
the cheeks B. These cheeks are hollowed and have openings at the sides D by
which the air enters.
This capsule can be applied to any burner and is fixed on it by the shoulder a.
In the annexed drawing the burner E which is represented, is a burner with
two holes and it is easy to understand that when this burner is furnished with a
capsule A B the flame in filling the opening C produces a draught of air more or.
less strong, through the openings D and the chambers of the cheeks B, according
as the pressure is more or less great. It follows then that the quantity of air
introduced will be proportioned to the quantity of gas burned and consequently
that the combustion of it will be complete whatever the pressure.
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:-
-
A capsule to regulate the admission of air with acetylene gas-burners distin-
guished by a cylindrical tube, to fit on the head of the burner, having an internal
shoulder and terminated above by two extensions or circular hollow cheeks with
lateral openings for the admission of air and separated by an empty space bounded
by the upper curved parts of the cheeks for disengaging the flame; the said cap-
sule being adapted to every system of acetylene burner for giving a quantity of
air proportioned to the quantity of gas burned, whatever may be the pressure of
gas, for the purpose of obtaining complete combustion of the gas.
