PRUVINIUNAL OF ECIFICATION.
Improvements in Gas Burners.
I, ROBERT RÖHER of 18 Lentstrasse, Tena in the Empire of Germany,
Mechanic do hereby declare the nature of this invention to be as follows :—
My invention relates to improvements in gas burners whereby whenever the
inflow of gas is increased or reduced, a corresponding increase reduction is effected
in the inflow of air, while in the case of burners having several jets, the number of
jets which are required to burn can be determined by merely turning the base of
the device so that a burner arranged to have several flames can be used whatever
may be the number of flames which are required to be alight at the same time.
The invention is described as applied to a Bunsen's burner, but it may be like-
wise applicable to any other burner. The base of the burner is provided with a
plug furnished with four openings, serving to supply the various jets with gas and air.
Upon the plug aforesaid is mounted a casing, which is divided by a partition
into three gas chambers below, and an equal number of air chambers above. Three
tubes or inner burners are screwed in the above casing, and communicate with the
gas and air chambers. Each air-chamber has two air inlets, which can be more or
less opened and closed by a circular valve, furnished with corresponding openings,
and with three teeth upon its outer periphery, which teeth gear with a toothed
segment arranged at the upper part of the gas inlet tube. These three teeth act
as stops to prevent the plug in the said inlet tube from being turned on too far.
It is thus obvious that at the same time as the inflow of gas is regulated the
opening of the air inlet is also correspondingly regulated. Owing to each flame having
its own air chamber, the introduction of air from the unused or closed burner is
fully prevented. The air chambers are closed at the top by a suitable cover.

COMPLETE SPECIFICATION.
Improvements in Gas Burners.
I, ROBERT RÖHER of 18 Lentstrasse Tena in the German Empire, Mechanician
do hereby declare the nature of this invention and in what manner the same is to
be perforined, to be particularly described and ascertained in and by the following
statement:-
My invention relates to improvements in gas burners whereby whenever the
inflow of gas is increased or reduced, a corresponding increase or reduction is
effected in the inflow of air, while in the case of burners having several jets, the
number of jets which are required to burn can be determined by merely turning
the base of the device, so that a burner arranged to have ten flames for instance,
can be still used when the number of flames which are required to be alight at the
same time is reduced to seven.
In the accompanying drawings
Fig. 1 is a vertical section of a treble burner on line A B of Figure 2 which is
a plan of the same.
Figure 3 is a horizontal section on line 1 of Figure 1.
Figure 4 is a similar section on line 2 of the same figure.
Figure 5 is a vertical section of a single burner and Figure 6 a horizontal
section on line CD of the same figure.

In the drawings the invention is shown as applied to a Bunsen's burner, but it
be likewise applicable to any other burner. The base.a of the burner (Figure 1)
is provided with a plug furnished with four openings
hereinafter more
fully described and serving to supply the various jets with gas and air.
Upon the plug is mounted a casing e which is divided by a partition d into three
gas chambers below and an equal number of air chambers g¹ g² g³ above.
The tubes or inner burners are screwed in the casing c aforesaid and
communicate with the gas and air chambers. Each air chamber has two air
inlets, and 3 which can be more or less opened and closed by the circular
valve furnished with corresponding openings kk, k² k², and k³ k³ and with two
teeth upon its outer periphery, which teeth gear with, a toothed segment
arranged upon the upper part of the gas plug 12 (Figure 2). These two teeth / act
as stops to prevent the plug in the inlet tube from being turned on too far.
It will now appear obvious that the opening of the air inlets is regulated with and
correspondingly at the same time as the inflow of gas. Owing to each flame having
its own air chamber, the introduction of air from the unused or closed burner into
the burners which are in use is fully prevented. The air chambers are closed at the
top by a cover m.
In the position of the plug shown in Figure 4, the gas enters through the inlet
tube into the canal thence through the chamber to the tube or inner burner ¹
and through the canal and the opening into the gas chamber and the tube
or inner burner 2, proceeding further through the canals 636, the short circular
opening and the opening into the gas chamber 3 and from there to the
tube or inner burner 43. When however the base a and with it the plug b is turned
against the casing, so that the canal and the opening n² no more coincide, no gas
can reach the chamber f2 and the tube or inner burner is out of use; yet gas can
flow through the circular opening and the opening ³, so that the tubes or
inner burners h¹³ are supplied with gas. If the base is turned further on, the
opening n becomes also closed and only the tube or burner can furnish a flame.
To enable this last burner to remain constantly alight with a very small flame, so
that the device may be rapidly brought into use a small circular opening is formed
in the plug of the inlet tube so that the amount of turning may be at once
ascertained from outside as is requisite in the case of 2, 3 or more flames, an index o
being arranged in the base a while the lower periphery of the casing c is furnished
with a corresponding division. p is a stop secured to the casing to prevent the
base from being turned on too far. By further turning the circular valve until
the toothed gearing is disconnected and the chambers are closed, the apparatus may
be used as a lighting device.
It will appear obvious that my invention is not only applicable to treble burners
but to apparatus furnished with any number of burners, the number of chambers
and of openings in the plug, having merely to be altered. An arrangement could
also be devised for altering the sequence in which the flames should be extin-
guished.
Figures 5 and 6 illustrate a single burner. There is also provided in this case
a circular valve k. which is furnished with teeth gearing with a toothed
seginent of the inlet tube plug 2 so that air and gas may be turned off together,
the casing c and the plug 6 being obviously dispensed with.
b
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 :-
1. A gas burner characterized by a circular valve k. furnished with parts or
openings and with teeth on its outer periphery gearing with those of a segment
formed on the upper part of the gas plug is, so that the inflow of gas and air may
be simultaneously increased or decreased substantially as herein described and
shown.
2. A multiplex gas burner characterized by the use of a special air chamber for

page_text: each burner tube in which the inflow of air is regulated by a circular valve k
connected by tooth gearing with the gas plug so that the air and gas may be simul-
taneously regulated substantially as herein described and shown.
C
3. In the multiplex burner claimed above the use of a casing a movable upon a
plug band base a and furnished with a gas chamber (one for each burner tube),
the plug being so perforated, that by turning the shell c upon the plug b one or
more flames is or are extinguished, that is to say the supply of gas thereto is cut
off, substantially as herein described and shown.
