COMPLETE SPECIFICATION.
Improvements in Gas Burners.
We, JULIUS SCHUCH of 15 Bergstrasse, Rixdorf, Germany, Manufacturer, and
HUGO KNEIDEL of 32 Fichte Strasse, Berlin, Germany, Manufacturer, do her hy
declare the nature of this invention and in what manner tho same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to a gas burner which is particularly adapted for
incandescent gas lighting and the characteristic feature of the invention is the
combination of a cylindrical mantle carrier and its mantle support with a mixing
disc, the parts being so fitted together that they can all be easily removed, at the
same time, for cleaning or repairing purposes.
The invention is illustrated on the drawings annexed, whereon,
Fig. 1 is a vertical section of the burner.
Fig. 2 shows in part section and Fig. 3 in vertical section modifications of the
burner.
Fig. 4 is a plan of the mixing disc.
Referring to the drawings:-
The gas pipe b, furnished with air holes a, is provided with a moulding c above which
are placed three brackets d held together by a guide ring e at the top and by
another ring at the bottom. The three brackets which are rivetted to the ring f
support, at their upper ends, the mixing disc g Fig. 1.
In the modification shown in Fig. 2 the rings e and connected together by the
brackets & rest on a tube i which is inserted over the tube and serves to support the
mixing disc in the following manner. The tube passes through the ring ea
sufficient distance to project slightly above the upper edge of the pipe b. The
part of the tube i projecting above has three lugs to which the mixing disc is
attached.
The gallery k for supporting the glass chimney is rivetted to the brackets d.
In the modification shown at Fig. 3 the circular gallery k is slipped down over
the burner tube until it reaches the moulding c over which it is drawn, as showa,
so as to tightly secure the gallery in place.
In this case, of course, we dispense with the brackets d and guide rings e and f.
In all these modifications the gas inlet pipe extends to the mouth of the burner
without admitting air or interfering with its subsequent admission. The air holes a
in the burner tube serve to produce the action of a Bunsen burner, or for the
sake of simplicity the same can be removed and replaced by an ordinary Argand
burner, which arrangement is shown in Fig. 3. The end of the gas inlet pipe is
screw threaded to receive the nipple of the burner. This nipple has screwed on
it a short tubular extension m about 25 m.m. in length and provided with four
holes arranged diametrically opposite each other and on the same line as the
holes a of the burner tube which is fitted telescopically on the extension.
turning the tube along with the parts placed above it, the air holes a
brought over the air holes n so as to coincide therewith and allow air to, enter
the tube so as to give a Bunsen flame, or, when desired, the entrance of air can
be prevented by turning the tube so as to cover the holes and give an Argand
flame. The burner tube carries at its upper end three lugs o whereto the mixing
dise g is rivetted in such a manner that the latter projects slightly above the end
of the burner tube in order to prevent, by the circulation of air, too high a
By
can be

page_text: temperature. The mixing disc has fitted centrally on it the mantle support to
which the mantle is fixed in the ordinary manner.
The disc g is provided with teeth on its periphery which may be undercut, as
at Fig. 1, or made to taper upwardly, as at Fig. 2.
The object of having the teeth is to break up the gas ascending the tube & into
small currents which are whirled about and intimately mixed with the air before
reaching the mantle.
This intimate mixture of the gas and air promotes combustion.
When it is desired to repair or clean the burner or its parts all that is necessary
is to merely grasp the brackets or the gallery in order to remove all the parts i.e., tho
mantle carrier, the mantle, and the mixing disc, at once. If it is desired to convert a
Bunsen into an 'Argand burner or rice versa the tube Fig. 3 with its parts is fitted
in place, in the one case the moulding e Figs. 1 and 2 and in the other the tubular
piece m Fig. 3 prevents the part pushed over descending too far.
The invention can be applied, where suitable, in other gas burners besides
incandescent burners."
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we consider novel and desire to claim is :-
1. A gas burner, having in combination the mantle carrier or holder, the disc g
fitted thereon, and the support fitted on the disc, substantially as and for the purpose
set forth.
2. In a gas burner, as claimed in Claim 1, the use of a toothed disc g having its
teeth undercut, as at Fig. 1, or made oblique or tapering, as at Fig. 2, substantially
as and for the purpose set forth.
3. In a gas burner, as claimed in Claim 1, the use of a tubular extension m, upon
which the tube is movably fitted, made with holes n corresponding with the air
inlets a of the tube b, substantially as and for the purpose set forth.
