do hereby declare the nature of this invention and in what manner the same
18 to be performed, to be particularly described and ascertained in and by the
following statement; —
This invention relates to an arrangement of buineis for petroleum stoves, in
which the petroleum 18 pressed in by the an pressure and is vaporized before
combustion. The purpose of the invention is to mingle the petioleum gas with
air as intimately as possible before the combustion and to heat the mixture, so
that an absolutely intimate combustion is attained. Moreover the device has the
advantage, that the combustion takes place without the sharp muimuring that
18 characteristic of most other petioleum stoves
Figure 1 of the drawing accompanying the Provisional Specification shows the
improved burner in vertical section, and
Figure 2 shows the same in plan
The tubes A form in the common way the so called burner clown which 18
connected with the vaporizing chamber B, situated immediately above the same
On this chamber the cone or casing C 18 aanged, which is connected with and
supported by the pipe D passing through the annulai vaporizang chamber B,
which pipe catches the petroleum gas escaping through the outlet E. Imme-
diately the gas arrives above the upper open end of the pipe D, it is deflected by
a horizontal disc F, which is connected with and closes the upper end of a
cylinder G surrounding the casing C The gas is thereby forced out to the sides,
and down through the space between the well of the cylinder and that of the
casing C. It then passes out beneath the lower edge of the cylinder G and into
the outer casing H, where it is ignited and breaks out in flames through radial
openings I (see Figure 2) in the upper side of the casing H
This latter is pre-
ferably made of a double conical form as shown in the diawing, and it is connected
with the vaporizing chamber B and supports the cylinder G
Owing to the long course the gas has to take before ignition, it has time to be
completely mixed with the air entering the burner and the heating of the
mixture within the cylinder G, will be very intense, as the cylinder is constantly
surrounded by the flame coming from its lower edge The device also contributes
to a rapid and complete vaporization, as the flame is immediately ignited on the
upper side of the vaporizing chamber B, in which a very high temperature 18
thus produced,
The air enters the gas pipe D through its lower open end as

page_text: shown by the arrows on the diawing. The introduction of the air in said tube
18 moreover effected by aid of the gas cuent which enters the tube with great
rapidity, thereby having a certain injector effect on the air
That no hissing sound arises, is due to the repeated obstacles which the burner
offers to the gas current
The position of the upper part of the casing H, ought to be so adjusted that
the hottest part of the flame will be situated somewhat above the openings I
This is necessary in order partly to effect a rather great heating capacity and
partly to protect the upper part of the casing against too strong a heating
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, as communicated to
me by my foreign correspondents, I declare that what I claim 18.
-
A burner for petroleum-stoves characteused by the arrangement of a cone or
casing (C) surrounding the upper part of a gas supply pipe (D) passing through
the crown, immediately above the upper end of which pipe there is a horizontal
disc (F), covering the upper end of the cylinder (G) surrounding at some distance
the casing, and the lower edge of which is situated somewhat higher than the
lower edge of the casing, and which cylinder (G) is surrounded by an outer
casing (H) connected with the burner-crown, which on the upper side is provided
with openings (1) through which the gas passing beneath the lower edge of the
cylinder (G) and there being ignited can break out in full flame, substantially as
hereinbefore described
