We, GUSTAVE LEBRUN of 17, Rue de Rivoli, Paris, France, Architect, anl
FERNAND CORNAILLE of 12, Rue du Havre, Paris, France, Merchant, do hereby
declare the nature of this Invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:-
This invention relates to a burner which is more particularly designed for
burning acetylene gas but adapted also as a burner for other gases rich in carbon.
The Invention has for its object to avoid the heating of the burner during
combustion of the gas and to prevent the accumulation of carbon deposits at the
base of the flame.
The Invention is illustrated by way of example in the accompanying drawing
in which Figure 1 represents an elevation and Figure 2 a vertical section of our
improved burner drawn on an enlarged scale. The same letters of reference denote
like parts in both figures.
r
a is the burner or nipple which is of hollow cylindrical form and with thin
walls and preferably made of opal glass set in a metal socket b as shown. Glass
is chosen as the material for the burner on account of its being a poor conductor of
heat and preference is given to white opal glass in order to lessen the radiation
of heat. It is however to be understood that the burner may be made of any
other kind of glass or of enamel or of other material possessing the same properties.
The extremity of the burner is made of paraboloidal form as shewn to aid in
the reflection of the heat rays. The orifice for the emission of the gas presents
externally the form of a hollow cone or crater with rounded edges the object being
to prevent the accumulation of carbon and the walls of the nose of the burner, (at
the centre of which is the orifice), is made of less thickness, as is shewn in Figure 2,
so that conformably to the principle on which the construction of the burner is
based, the continuous supply of fresh gas as combustion proceeds serves to cool the
interior of the burner and limit its rise in temperature.
The burner a is preferably sealed in the metal socket 6 by a fireproof cement
composed of a silicate and asbestos and the joint, completed with an external filling
of white lead. The base of the metal socket 6 has a central hole d which acts as
a moderator and ensures the interior of the burner being kept clean or free from

page_text: deposit. It will be obvious that the means of fixing the burner in its socket may
be varied, without in any way changing the nature of the Invention.
Having now particularly described and ascertained the nature of the said Inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
A burner for acetylene gas and other gases rich in carbon, consisting of a hollow
cylindrical body having thin walls, and made of glass or other material which is a
poor conductor of heat, and having its upper rounded extremity made of para-
boloidal form and provided with an emission orifice for the gas made trumpet
shaped on the exterior and rounded on the interior so that the heating of the burner
during combustion and the accumulation of carbon deposits is minimized; said
burner being sealed in a metal socket having a central perforation at its base to act
as a moderator and ensure the interior of the burner being kept clean and free
from deposit.
