Improved Air Regulating Device, applicable to Bunsen's Gas
Burners.
I, WILHELM HEINRICH AUGUST SIEVERTS, Teacher, at the Orphan House, in the
City of Hamburg, Germany, do hereby declare the nature of this invention to be as
follows:-
This invention relates to an improved air regulating device applicable to Bunsen's
gas burners and it mainly consists of a slip of paper or of other suitable material
impermeable to air and provided with perforations coinciding with the air inlet holes
in the base of the burner, and adapted to be glued together in the form of a ring
or socket after being placed around the base of the burner in order to partly cover
the said air inlet holes and to thereby regulate the supply of air in proper proportion
with the gas supply.
It is also the perforated slip of paper capable of being united in the form of a
ring around the gas burner by the user himself which makes the subject matter of
the present invention and which in this slip-form shall be put on the market.
The improved air regulating device, that is to say, the perforated paper slip, is
preferably designed to be used in or applied to incandescent gas light burners in
which a considerable waste of gas is caused by the air inlet holes not being in
proper proportion with the gas outlet holes. But when an improved regulating
slip is applied to such a burner in order to partly cover the said air inlet holes
and to reduce the air supply in proper proportion with the gas supply, a considerable
amount of gas will be saved, without reducing the illuminating power of such a gas
burner.
In opposition to the known metal rings or sockets mounted on the base of
Bunsen's gas burners, the above described improved regulating device guarantees
the advantages that it can be easily fitted to any existing Bunsen's gas burner
without dismounting the latter, that when applied it closely embraces or surrounds
the base or air inlet pipe of the burner and that it does not stick to the latter by
oxiding.

COMPLETE SPECIFICATION.
Improved Air Regulating Device, applicable to Bunsen's Gas
Burners.
I, WILHELM HEINRICH AUGUST SIEVERTS, Teacher, at the Orphan House, in the
City of Hamburg, 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 :-
This invention relates to an improved air regulating device applicable to Bunsen

page_text: gas burners, and it consists mainly, of a slip of paper, or of other suitable matter,
impermeable to air, provided with perforations coinciding with the air inlet holes
in the base of the burner, and adapted to be glued together in the form of a ring
or socket after being placed around the said base of the burner, in order to partly
cover the said air inlet holes and to regulate thereby the supply of air in proper
proportion with the gas supply.
The present invention includes also a perforated slip of paper capable of being
united in the form of a ring about the gas burner, by the user himself.
In order that my invention may be fully understood I have represented my
improved air regulating device on the accompanying drawing, in which,
Figure 1 shows, for example a properly perforated slip of paper a a', provided
with glue at one of its short sides as indicated at a²; and
Figure 2 illustrates how the said paper-slip a may be applied to a Bunsen gas
burner b as employed for incandescent gas lighting.
The improved air regulating device, that is to say, the paper slip a provided with
perforations a¹ at proper distances apart, is, preferably, designed to be used on or
applied to incandescent gas light burners in which a considerable waste of gas is
caused by the air inlet holes 6 not being in proper proportion to the gas supply.
But when an improved regulating slip a a' is applied to such a burner 6 in order to
partly cover the said air inlet holes & and to reduce the air supply in proper proportion
to the gas supply, a considerable amount of gas will be saved, without reducing the
illuminating power of the gas burner.
In opposition to the known metal rings or sockets mounted on the base of Bunsen
gas burners, the above described improved regulating device possesses the advantages
that it can be easily fitted to any existing Bunsen gas burner without disconnecting
the latter, that when so fitted, it closely embraces or surrounds the base or air inlet
pipe of the burner, and that it does not stick to the latter by getting rusted to it.
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
1 claim is :-
As a new article of manufacture, an improved air regulating device applicable to
Bunsen's gas burners and consisting of a slip of paper or other suitable matter
impermeable to air provided with perforations coinciding with the air inlet holes of
the burner, and adapted to be united in the form of a ring or socket, substantially as
and for the purpose specified.
