Improvements in Petroleum Burners.
I, HUGO SCHNEIDER, of 52 Kohlgartenstrasse, Leipzig-Reudnitz, in the
Kingdom of Saxony, German Empire, Manufacturer, 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 :-
The subject of this invention is a circular petroleum burner fitted with a com-
bustion-disc of that class in which, at the part where the flame is formed, a glass
chimney of spherical shape is made use of to keep up the supply of air.
Burners of this description, as hitherto constructed, have been attended by the
drawback that, when employed for petroleum having a high flashing point, they
are apt to yield an unsteady and defectively burning flame.
According to the present invention, the abovementioned inconvenience is
remedied by so arranging that that part generally known as "the neck" comprised
between the gallery and the wick-tube,-the same being of a slightly tapering
shape and having for its object to assist the proper control of the admission of air
to the flame, terminates, say, from two to twenty millimetres below the upper
edge of the wick-tube, instead of, as hitherto, rising to about the level of the wick-
tube, and at the same time providing a distributing sieve or perforated plate in the
top part of the burner in either a horizontal or vertical position, for the air to pass
through.
A burner constructed in accordance with this invention is represented in the
accompanying drawing in sectional elevation.
Ou to the lower part a of the burner, which is secured to the lamp body or
reservoir in the usual manner,-the top part thereof, integral with a gallery c and
a neck d, is screwed, likewise in the well known manner.
As will be seen from the drawing, the upper edge of the neck d is situated a
considerable distance below the upper edge of the wick-tube e. According to the
flashing point of the oil, the difference between the respective levels of the upper
edges of the neck d and the wick-tube e must be varied and properly adjusted
within the limits of two and twenty millimetres; this is the essential novel feature
distinguishing the present invention from all the burner constructions hitherto
known.
Within the top of the burner there is further arranged a distributing sieve ƒ for
the admission of the air, which sieve in the form of apparatus shown in the drawing
assumes a vertical position. The same object might be attained however by
arranging a transverse or horizontal sieve in a convenient position.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A circular petroleum burner with a burner disc and ball-shaped chimney
constructed for burning petroleum having a high flashing point the main feature
of such burner being the provision of a neck such as d having a somewhat conical
shape and comprised between the burner gallery and the wick-tube and being
shorter than the said wick-tube by from about two to twenty millimetres,
substantially as described.

page_text: 2. In a petroleum burner the horizontal or vertical distributing sieve, such as f,
for the admisssion and distribution of the air into and within the top part of the
burner, substantially as described.
3. In a petroleum burner the combination of the neck shorter than the wick-
tube by from about two to twenty millimetres with a horizontally or vertically
situated distributing sieve f in the top part of the burner d, substantially as
described.
