An Improvement in Burners for Incandescent Gas Lights.
I, LOUIS DENAYROUZE of 70 Boulevard Victor-Hugo, Neuilly (Seine) France,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention has for its object to obtain increased intensity of heating power
directed on an incandescence mantle and consequent increased luminosity.
For this purpose, three or more Bunsen burner tubes arranged circularly on a
chamber supplied with gas and receiving air by lateral orifices near their bases in
the usual way, open at the top into an annular chamber formed around a central
air tube, this chamber being about the height of the blue cone usually seen in a
Bunsen flame, and having its mouth covered with wire gauze. No air being
admitted to the glass chimney, the burner as well as the central air tube is subject
to the draught, and, while the flame issues from the meshes of the wire gauze, the
air current issuing by the central tube and expanding laterally, directs the flame
against the sides of the suspended mantle which extend down a little under the
mouth of the burner, and which are thus intensely heated.

An Improvement in Burners for Incandescent Gas Lights.
I, LOUIS DENAYROUZE, of 70 Boulevard Victor-Hugo, Neuilly (Seine) France,
Engineer, 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 has for its object to obtain increased intensity of heating power
directed on an incandescence mantle and consequent increased luminosity.
For this purpose I construct a burner as I shall describe referring to the
accompanying drawings, Fig. 1 is a vertical section, Figs. 2 and 3 are horizontal
sections on the lines 2-2 and 3-3 of Fig. 1 respectively, three or more Bunsen
burner tubes A arranged circularly on a chamber supplied with gas and receiving
air by lateral orifices near their bases in the usual way, open at the top into an
annular chamber G formed around a central air tube T this chamber being about
the height of the blue cone usually seen in a Bunsen flame, and having its mouth
covered with wire gauze. No air being admitted to the glass chimney, the
burners A and G as well as the central air tube T are subject to the draught, and,

by the central tube and expanding laterally, directs the flame against the sides of
the suspended mantle M which extend down a little under the mouth of the burner,
and which are thus intensely heated.
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 light consisting of several Bunsen burner tubes
leading into an annular chamber covered by wire gauze and surrounding a central
air tube, constructed and operating, substantially as described with reference to the
drawings.
