An Improvement in Bunsen Burners for Incandescence Gas
Lighting.
I, JULIUS MOELLER, of 14, Palmer Street, Westminster, in the County of London,
Manager, do hereby declare the nature of this invention to be as follows:-
My invention relates to a bunsen burner for incandescence gas lighting so
constructed that the mixture of gas and air which supplies the flame is highly heated
before it burns.
For this purpose, instead of lighting the flame at the top of the tube which the
mixture of air and gas ascends in burners as they are usually constructed, I place
over the tube a deep inverted cup of refractory material so that the mixture is
deflected at the top of the tube and descending the annular space surrounding the
tube towards the closed mouth of the cup at the bottom, issues by lateral orifices so
as to form an annular flame surrounding the cup. An incandescence mantle supported
at the top of the cup and descending all round the cup but separated from it by an
annular space, becomes highly heated by the annular flame, giving light by its
incandescence. The refractory cup within the mantle, being also highly heated,
imparts heat to the mixture of gas and air descending within it, thus rendering the
combustion more intense.

Lighting.
I, JULIUS MOELLER, of 14, Palmer Street, Westminster, in the County of London,
Manager, 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 :-
My invention relates to a bunsen burner for incandescence gas lighting so
constructed that the mixture of gas and air which supplies the flame is highly heated
before it burns.
For this purpose I construct the burner as shewn in the accompanying
drawing, Fig. 1 being a vertical section and Fig. 2 an elevation of the cup. Instead
of lighting the flame at the top of the tube which the mixture of air and gas
ascends in burners as they are usually constructed, I place over the tube A a deep

tube A and descending the annular space surrounding the tube towards the closed
mouth of the cup at the bottom, issues by lateral orifices B so as to form an annular
flame surrounding the cup C. An incandescence mantle M supported at the top of
the cup and descending all round the cup but separated from it by a small annular
space, becomes highly heated by the annular flame giving light by its incandescence.
The refractory cup within the mantle, being also highly heated, imparts heat to the
mixture of gas and air descending within it, thus rendering the combustion more
intense. G is the glass chimney enclosing the mantle.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
A burner for incandescent gas lighting substantially as described with reference to
the drawings.
