PROVISIONAL SPECIFICATION.
Improvements in Bunsen Burners, specially adapted 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 the construction of a Bunsen burner in such a manner
as to obtain a very thorough mixture and also certain heating of the gas and air
current on its way to the flame.
For this purpose I employ three concentric tubes, an innermost tube into the
bottom of which air is drawn by the injector action of the gas issuing from small
orifices at the bottom, a second tube closed at the top and surrounding the innermost
tube, so that the mixture of gas and air which ascends the innermost tube is de-
flected at its top and caused to descend the annular space surrounding the innermost
tube. The current then ascends an annular space within the third or outermost
tube to the opening of this tube at the top which is covered with wire gauze or per-
forated metal.
From the top of the middle tube a metal stem extends upwards through the
centre of the flame to carry the incandescence mantle, and this conducts heat down
to the tubes below by which the current of mixed gas and air is more or less
heated.
Besides the air entering at the bottom of the innermost tube, air may also enter
by orifices at the bottom of the outermost tube, and air also enters the orifices of
the gallery which supports the glass chimney.
A burner of the kind described may obviously be employed for heating purposes
generally.

Improvements in Bunsen Burners, specially adapted 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 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 the construction of a Bunsen burner in such a manner

page_text: as to obtain a very thorough mixture and also certain heating of the gas and air
current on its way to the flame.
For this purpose I construct the burner as I shall describe referring to the
accompanying drawings. Fig. 1 is a vertical section and Fig. 2 is an elevation,
I employ three concentric tubes, an innermost tube A into the bottom of which air
is drawn through orifices a by the injector action of the gas issuing from small
orifice B at the bottom, a second tube C closed at the top and surrounding the
innermost tube, so that the mixture of gas and air which ascends the innermost
tube is deflected at its top and caused to descend the annular space surrounding the
innermost tube. The current then passing through slits cascends an annular space
within the third or outermost tube D to the opening of this tube at the top which
is covered with wire gauze or perforated metal d.
From the top of the middle tube a metal stem E extends upwards through the
centre of the flame to carry the incandescence mantle M and this conducts heat down
to the tubes below by which the current of mixed gas and air is more or less heated.
Having now particularly described and ascertained the nature of this invention,
and in what manner the same is to be performed, I declare that what I
claim is:
-
A Bunsen burner constructed and operating, substantially as described with
reference to the drawings.
