PROVISIONAL SPECIFICATION.
Improvements in and relating to Petrol-burners for Lamps,
Lanterns, and the like.
I, ISIDOR SCHWARZ, of 88, Zwickauer Strasse, of Chemnitz, in the Kingdom of
Saxony, German Empire, Manufacturer do hereby declare the nature of this
invention to be as follows:-
In all the sorts of petrol-burners that have become known to me up to now,
there is the drawback, that the residues of the burnt wick falling down into the
interior of the burner, or upon the sieve-bottom arranged within the burner
respectively, cause a decrease in the quantity of the air flowing through the burner
to the flame. The latter therefore becomes yellow or red, and is oftentimes caused
to burn with smoke. The great inconveniences, resulting therefrom are known,
and need therefore not be told. Moreover, I have found, that burning with smoke
very easily occurs, if the burner, or lamp or lantern respectively, is exposed to an
outer draught of air. The purpose of my invention is to prevent this drawback as
well as the other one above mentioned.
My improved burner is shown in the accompanying drawing, and is constructed
as follows:-
:-
The wick-tube a having in its lower portion the known wheel-work (not shown)
for moving the wick is surrounded by, or arranged within, a shell b which, contrary to
former constructions, is of cylindrical shape, instead of bellied one. Said shell is
perforated in its whole height, and forms at its upper rim the clamp b¹ for holding
the chimney c. The latter is perfectly cylindrical, i.e. is neither contracted nor
bellied in any part and is supported either by a contracted portion b³ of shell b, or
by a wire-ring 63 secured to the inner side of said shell.

1, ISIDOR SCHWARZ, of 88 Zwickauer Strasse of Chemnitz, in the Kingdom of
Saxony, German Empire, Manufacturer do hereby declare the nature of my said
invention, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-

interior of the burner, or upon the sieve-bottom arranged within the burner
respectively, cause a decrease in the quantity of the air flowing through the burner

outer draught of air. The purpose of my invention is to prevent this drawback as
well as the other one above mentioned.
My improved burner is shown in Figs. 1-3 of the drawing sent in with the
Provisional Specification, and in Figs. 4 & 5 of the drawing accompanying the
present Complete one.
The wick-tube a having in its lower portion the known wheel-work (not shown)
for moving the wick is surrounded by a shell b, which, contrary to older
constructions, is of perfectly cylindrical shape, instead of bellied one, and of a
diameter that but very slightly exceeds that of the chimney c. Said shell is
perforated throughout its whole height and forms at its upper rim the clamp b¹ for
holding said chimney c. The latter is also perfectly cylindrical, i.e. neither
contracted nor bellied in any part, and is supported either by a contracted
portion of shell (Figs. 1 & 2), or by a wire-ring 63 (Fig. 3) secured to the
inner side of said shell, or by a flat ring 64 (Fig. 4) also secured to the said shell,
and extending inwards rather close to the wick-tube a. When employing said
ring, I prefer to use a wick-tube of but such a height, that the said ring is on a
level with the upper edge of said shortened wick-tube a.
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. In a lamp or lantern, the combination with a cylindrical perforated shell
enclosing the wick-tube, of a cylindrical chimney supported by said shell, sub-
stantially as described.
2. In a lamp or lantern, the combination with a cylindrical perforated shell
enclosing the wick-tube, of a cylindrical chimney supported by a ring fixed to
said shell, said ring being arranged on, or nearly on, a level with the upper edge of
said wick-tube, substantially as described.
