PROVISIONAL SPECIFICATION.
Improvements in Chimneys for Lamps, Lanterns, and the like..
I, ISIDOR SCHWARZ, of 154 Linien Street of Berlin, Kingdom of Prussia,
German Empire, Manufacturer do hereby declare the nature of this invention to
be as follows:-
This invention refers to chimneys as used for lamps, lanterns, and the like, and
my improvements in chimneys of said kind relate to a special configuration or to
special configurations of the same, or more particularly to a special horizontal
section or to special horizontal sections of said chimneys. The chimneys known
and used up to now are with regard to their horizontal. sections either perfectly
circular, or partly circular and partly oblong, or partly circular and partly non-
circular respectively. Chimneys of this latter scrt are omployed, for instance,
with lamps or lanterns having a flat burner, or a flat wick-tube or flat wick-tubes
respectively, and there is in said chimneys the oblong or non-circular portion
situated in the middle, or between the circular base-portion and the circular top-
portion respectively.
My invention consists in making the chimneys non-circular throughout their
whole height or length.
I have found, that by doing so, the flame of a flat burner is entirely prevented
from becoming pointed, and that, moreover, the length or height of such a chimney
may be considerably reduced without causing the flame to become unduly small, or
to smoke. My novel chimney is not liable to cracking or bursting, and is from all
the reasons afore given especially adapted for use with lanterns, in which generally
the space is a very limited one.
I have as an example shown in the accompanying drawing a chimney a with an
oblong section, but I wish it to be understood, that I do not confine myself to
exactly that section, or form of section respectively. The form of section may be
more or less oblong, or may, if desired, represent a true ellipse or oval or similar
shape.

I, ISIDOR SCHWARZ, of 154 Linion Streat, of Berlin, Kingdom of Prussia,

and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-

I have as an example shown in the drawing seut in with provisional application
a chimney a with an oblong section, but I wish it to be understood, that. I do not
coufine myself to exactly that section, or form of section respectively. The form
of section may be more or less oblong or may, if desired, represent a true ellipse or
oval or similar shape.
Having now particularly described the nature of my said invention, and in what
manner the same is to be performed, I declare that what I claim is :—
1. A chimney for lamps, lauterns and the like, having an oblong or non-circular
section throughout its whole length or height, for the purpose as described.
2. A chimney for lamps, lanterns and the like, having one and the same oblong
or non-circular section throughout its whole length or height, for the purpose as
described.
3. In a lamp, lantern and the like, having an oblong or non-circular burner, the
combination with said burner, of a chimney having also an oblong or non-circular
section, and having said section throughout its whole length or height, for the
purpose as described.
