COMPLETE SPECIFICATION.
An Improved Burner for Oil Lamps.
I, ALFRED LENNER, of Kandlgasse 15, Vienna, in the Austrian Empire, Merchant,
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 present invention refers to
factory burning can only be
having the wick fixed
as otherwise
the well known drawbacks and inconveniences, such as the flame show-
ing an inclination to smoke, unsteady burning, development of odour, decreased
power of lighting and the like will result. The cause of all these drawbacks
can be found on the one hand, in the arrangement of the air supply in such a
manner that the rising air currents have to cross each other and thus are diminished
in their speed whereby consequently not sufficient air reaches the flame, and, on
the other hand, in the flame burning from the whole of the wick projecting
from the wick tube.
The purpose of the present invention is to produce a burner, having two
independent air supplies, a central or inner one, and an external or outer one, which
air supplies, in view of their unhindered passage prevent a burning down of the
flame on the projecting wick portion, on the other hand attaining a flame con-
stantly burning or emitted from the top end of the wick only. This entails the
advantage of producing a flame which even although considerable variations in
the height of the projecting wick may prevail, is uniformly supplied with air,
thus completely preventing smoking and the like of the flame.
I will now proceed to more fully describe my invention, reference being had to
the accompanying drawings, in which a vertical section of my improved burner for
oil lamps is illustrated. The outer wick tube a and the inner wick tube a¹ are
connected with the gallery e in any suitable well-known manner; the top part e
of the gallery serves in the usual way for the reception of the chimney, the latter
being of cylindrical shape throughout. The lower part of the gallery c is per-
forated the external or outer air supply entering through these perforations.
The central or inner air supply may enter through the inner wick tube a', the
latter projecting downwards into and through the oil-reservoir of the lamp, or it
may enter through a slot k in the outer and inner wick tube a and a respectively,
passing through the wick b. To increase the air supply to the inner wick tube a¹
through the slot k a cap or hood 1, opening downwards, is arranged around the
wick tubes. In view of the increased central or inner air supply produced in the
manner just described it will be necessary, to attain the required uniformity
between the two air supplies, to increase the external or outer air supply, which
is attainable by raising the lamp chimney relatively to the holder as required.
The light obtained will by virtue of the arrangements above described be more
luminous and the flame will be more steady than it is possible to attain without
the use of the can or hood 7.

page_text: 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) The combination with a burner for oil-lamps of the kind described of a lamp
chimney cylindrical throughout and of two uniform and independent air supplies
of equal volume and rising in a like direction for the purpose as described.
2) The combination with a burner for oil-lamps of the kind described of a
cap or hood, opening downwards, surrounding the wick tubes, through a slot in
which the central or inner air supply enters, substantially as and for the purpose
described.
3) The combination with the outer wick tube of a burner for oil lamps as
described of an inner wick tube projecting into and through the oil reservoir as
and for the purpose described.
4) An improved burner for oil lamps, the whole constructed, arranged and
adapted to operate substantially as described with reference to the accompanying
drawing.
