page_text: I, GEORG KRON, of Heibergsgade 16, Copenhagen, in the Kingdom of Denmark,
Engineer, do hereby declare the nature of this invention to be as follows:-
-
This invention relates to burners for incandescence petroleum lamps adapted to
produce Bunsen flames that burn with perfect regularity and do not give off any
smoke.
Figs. 1 and 2 of the accompanying drawings show two burners according to
this invention in vertical section.
The wick a is enclosed between and guided by two concentric tubes b and c in
the usual manner. Above these tubes is arranged a cap d having at the top an
opening between the edge of which and the edge of a spreader is left a free,
narrow, and annular space f placed almost over the upper end of the wick.
Over the upper end of the wick there is bent the edge g of a cap h which is
slipped over the outer wick-tube. The object of this arrangement is a double
one: First, the pressing down flat of the upper part of the wick prevents the
flame from smoking and the incandescent tissue from being blackened by
the small salient pieces of the wick, as the transformation into gas of the
petroleum, drawn up by the wick, only takes place at the inner side of the wick
and not at its upper surface; secondly, the gases produced at the inner side of the wick
are compelled, before reaching the aperture f, to take a serpentine course, which
secures an intimate mixing with the air which comes from both outside and
inside the wick cap, mantle or casing.
In the example shown in Fig. 1 the cap h simply rests on the upper surface of
the wick and moves up or down with the wick, whilst in that shown in Fig. 2
the cap h rests on an inner projection i on the cap d in order that the wick may
be raised before it bears against the edge g.
The lamp is lit after raising the gallery with the chimney and net or mantle
and removing the caps d and h. After these parts have been replaced and the
wick has been raised slightly, the bright-burning flame changes into a Bunsen
flame that renders the tissue or mantle incandescent.

I, GEORG KRON, of Heibergsgade 16, Copenhagen, in the Kingdom of Denmark,
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 relates to burners for incandescence petroleum lamps adapted to
produce Bunsen flames that burn with perfect regularity and do not give off any
smoke.
Figs. 1 and 2 of the drawings filed with my Provisional Specification show two
burners according to this invention in vertical section.
The wick a is enclosed between and guided by two concentric tubes b and c in
the usual manner. Above these tubes is arranged a cap d having at the top an
opening between the edge of which and the edge of a spreader is left a free,
narrow, and annular space f placed almost over the upper end of the wick.
Over the upper end of the wick there is bent the edge g of a cap h which is
slipped over the outer wick-tube. The object of this arrangement is a double
one: First, the prèssing down flat of the upper part of the wick prevents the
flame from smoking and the incandescent tissue from being blackened as is the case
when the top of the wick is jagged or uneven, as the transformation into gas of the
petroleum, drawn up by the wick, only takes place at the inner side of the wick
and not at its upper surface; secondly, the gases produced at the inner side of the wick
are compelled, before reaching the aperture f, to take a serpentine course, which
secures an intimate mixing with the air, which comes from both outside and
inside the wick casing.
In the example shown in Fig. 1 the cap h simply rests on the upper surface of
the wick and moves up or down with the wick, whilst in that shown in Fig. 2
the cap rests on an inner projection on the cap d in order that the wick may
be raised before it bears against the edge g.
The lamp is lit after raising the gallery with the chimney and net or mantle
and removing the caps d and 7. After these parts have been replaced and the
wick has been raised slightly, the bright-burning flame changes into a Bunsen
flame that renders the tissue or mantle incandescent.
Having now particularly described and ascertained the nature of the saich
invention and in what manner the same is to be performed I declare that what
I claim is:
1. A burner for an incandescence oil lamp in which the upper surface of the
wick is covered by the bent edge of a cap that is slipped over the outer wick-tube,
for the purpose of producing the transformation into gas of the oil, raised by
means of the wick, only on the inner side of the wick.
2. Burners for incandescence oil lamps constructed arranged and operating
substantially as shewn in and described with reference to the drawings.
