Improvements in Gas Burners for use
Incandescent Mantles.
with Self-igniting
We, RICHARD BEESE, Architect, of 13, Gluckstrasse, Dresden, Germany, and
ALBIN PERLICH, Civil Engineer, of 34, Lauensteinerstrasse, Dresden-Striesen,
Germany, 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 :-
Our invention has reference to improvements in gas burners with self-igniting
Auer filaments or incandescent mantles and relates more especially to means
whereby the self-igniting top of the mantle is provided with a jet of a mixture of
gas and air of just the right proportion to insure its working. As is well known
the initial glowing of the self-igniting top of incandescent mantle is brought about
by the mixture of gas and air impinging upon it. To insure the initial glowing the
inflammable mixture must consist of an absolutely unvariable proportion of gas and
air, which is very rarely attained in the ordinary burner. To set up the initial glowing
of a surety, we conduct a small quantity of gas by means of a narrow tube to the
self-igniting top of the incandescent mantle, where it leaves the tube in the form of
a number of very fine jets, a number of fine holes being provided at the extremity
of the pipe. As the gas jets are projected out of the tube, the outer air mixes with
them and jets of inflammable mixture of various compositions will result, one or
more of which will just contain the indicated proportions to set the top of the
mantle aglowing. The main jet of inflammable mixture ascending from the burner
head proper now coming in contact with the glowing top will be ignited and heat
the whole mantle to a white glow.
In order to make our invention more readily understood, we have shown in the
accompanying drawing two ways of carrying out our invention, but we do in no
way restrict ourselves to these particular constructions.
Fig. 1 represents a side elevation of a burner according to our invention.
Fig. 2 shows a modification, in which the pin supporting the mantle is used as
auxiliary gas conducting tube.
Fig. 3 is an enlarged sectional elevation of the auxiliary gas conducting tube,
showing the arrangement of the holes.
a is the main gas feed pipe, b is the well known mixing chamber, with holes c
for the admission of outer air, d is the incandescent mantle, e the self-igniting top.
f is the pin supporting the mantle and g is the auxiliary gas tube, being provided
with holes i near the upper end.
Instead of using a separate auxiliary gas tube g, we may employ the pin f to
conduct the unmixed gas below the self-igniting top of the mantle. In this
case, the holes i are provided below the crescent or hook shaped upper end of the
said pin, as is clearly shown in Fig. 2.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:-
1 In a burners with self-igniting incandescent mantles means to insure the

page_text: initial glowing of the self-igniting top of the mantle consisting in an auxiliary gas
tube, conducted upward within the mantle and out of which the gas-is ejected
in a number of fine jets upon the said self-igniting top as and for the purpose set
forth.
2. In gas burners with self-igniting incandescent mantles the employment of the
pin supporting the mantle as auxiliary gas tube, said pin to be hollow and to be
provided with a number of apertures near its upper end, as specified.
3. In gas burners with self-igniting incandescent mantles the combination of the
gas feed pipe, a, the mixing chamber, b, the pin f, supporting the incandescent
mantle d having a self-igniting top e and the auxiliary gas tube g having holes i
provided, as shown and specified.
4. In gas burners with self-igniting incandescent mantles the combination of the
gas feed pipe a, the mixing chamber b, the hollow pin f, having holes i near its
upper end and being connected to the gas main a, and the incandescent
mantle d having a self-igniting top e, substantially as set forth.
