Improvements in Gas Burners.
I, HENRI CLAUDE, of Rue Melsens No. 10, Brussels, Belgium, Jeweller, 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 a new Bunsen gas burner for producing a flame larger
and of greater intensity than existing Bunsen burners and specially adapted to
be employed with incandescence mantles made of fabric consisting of metallic
threads.
A burner constructed according to this invention essentially comprises a tube
whose lower part is perforated or reticulated so as to give a free passage for air
and which is fitted on a gas distributor formed of a metal disc with a nipple threaded
internally in order to be screwed on the outlet end of the gas-supply pipe. The
disc is provided around its centre with a number of small perforations for the
passage of the gas and to the centre of its upper face there may be fixed or cast
with it a small inverted cone for directing the jets of gas towards the inner surface
of the imperforate or non-reticulated part of the tube or chimney. The perforations
of the disc are made in such a manner that the jets of gas, traverse the perforated
or reticulated part of the tube and strike the internal surface of the latter above
the perforated or reticulated part either directly or after having struck the surface
of the directing cone.
The top
of the tube may he provided with an incandescence mantle and a glass
chimney and around the perforated or reticulated part of the tube there may be
placed a screen arranged in such a manner as to allow the air to have free access
to the perforated or reticulated part of the chimney.
Fig. 1 of the accompanying drawings represents a burner tube with a reticulated
lower part according to this invention;
Fig. 2 represents a gas-distributor with divergent passages for the gas and a
directing-cone;
Fig. 3 represents a similar distributor having gas-passages that converge towards
the central cone and
Fig. 4 an analogous distributor with divergent passages for the gas and without
a dircoting-cone; and
Fig. 5 shows a complete burner with a screen arranged around the perforated or
reticulated part of the tube.
In the figures a represents the burner-tube; b the reticulated part of the latter,
c the disc of the gas-distributor; d, d the perforations in the disc for the passage
of the gas; the cone that directs the jets of gas; and, 'a screen formed of metal
leaves or plates that leave between them spaces for the circulation of air.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is :-
A gas burner comprising a tube whose lower part is perforated or reticulated as
set forth so as to give free passage of air and which is fitted on a gas distributor in
the form of a disc provided around its centre with a number of perforations, the

page_text: arrangement being such that jets of gas issuing from the perforations will be
directed against the full part of the wall of the tube above the perforated or
reticulated part, substantially as described and shown and whether or not an
inverted cone be fixed above and at the centre of the diso as set forth.
