Improvements in Lanterns for Cycles and the like.
I, ISIDOR SCHWARZ, of 154A, Linien Strasse, of Berlin, Kingdom of Prussia,
German Empire, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
This invention refers to lanterns, especially such as are used with bicycles,
tricycles, and the like, and my improvements in said lanterns relate to the arrange-
ment of ribs upon the outer wick-tube, said ribs being intended to support the
chimney.
Referring to Figures 1 & 2 a is the outer wick-tube, b b are the ribs, and c is
the lower part of the chimney. In Figures 3 & 4 the ribs are not secured to the
wick-tube a, but they are connected by a ring d, and the system b d may thus
be shoved upon the wick-tube of a finished burner. If desired, the ribs b may be
formed into a kind of wings (Figures 5 & 6) so as to cause a rotation of the air
ascending between the wick-tube and the chimney. The ribs b may be hollow
(Figures 7 & 8) so as to resemble each a piece of tube that has been obliquely
cut off at one side.

Improvements in Lanterns for Cycles and the like.
I, ISIDOR SCHWARZ, of 154A, Linien Strasse, of Berlin, Kingdom of Prussia,
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:-
T
This invention relates to improvements in lanterns for cycles and the like, and
more particularly to the chimney-carriers of the burners of such lanterns. The
invention is more especially intended, as indicated, for use in cycle-lanterns or
lamps, but may also be applied to other burners, and my improvements in the
chimney-carriers of these burners relate to constructing the same in such manner
or giving them such shape, that the chimney may be put upon the carrier approxi-
mately level with the burning surface of the lamp wick, whereby air is caused
to pass to the burner in a heretofore unattained degree by means of which an
intense and concentrated flame is obtained in a very small space.
In order to make my invention more clear, I refer to the accompanying draw-

page_text: ings, which show the construction illustrated in the drawings filed with the
Provisional Specification, and several constructions embodying the same principle
mentioned in the said Provisional Specification.
Figure 1 shows in plan and elevation a wick-tube with ribs attached to the
burner.
Figure 2 represents in plan and elevation a burner in which the ribs are not
secured to the wick-tube, but to a ring d; the ribs and ring being simply pressed
upon the wick-tube.
Figure 3 shows in plan and elevation the ribs so shaped as to resemble some-
what the form of wings, by means of which the air is caused to travel round a
spiral path in ascending to the burner.
Figures 4 & 5 show two modified forms of hollow ribs,
Figure 6 represents in plan and elevation ribs of diminished width so as to
allow of a still greater access of air to the burner.
My invention is based upon the idea to secure within a very narrow space a
concentrated and powerful flame, this being especially necessary for bicycle
lanterns. The constructions hitherto in use when arranged with a wide chimney
carrier develop too great heat and furthermore often also smoke to such an extent
as to produce a yellow flame.
My improved construction permits of the passage of air in a rapid and extensive
manner to all parts of the flame, my improved carrier being shown in several
modifications in the accompanying drawings which form part of this specification.
Referring to the drawings the construction is of so simple a character and the
various chimney-carriers shown, form merely modifications of the same principle,
that I think I may abstain from any lengthy description, otherwise than to state
that the ribs forming the chimney-carrier may either consist of three ribs as.
shown in Figure 1, or the chimney-carrier may be provided, as shown in Figure 2,
with four ribs, or, as shown in Figure 3, the said ribs may have the form of
wings.
In the drawing 66 (Figure 1 &c.) are the ribs; c the lower portion of the
chimney, and a the wick-tube.
In each of these improved chimney-carriers the said chimney is, as indicated,
at a level or approximately at a level with the flame of the wick, this being also
a main characteristic of my invention, and which also very. considerably
facilitates, as indicated, the access of air to the flame.
Furthermore the chimney may either be cylindrical, as used in Figures 1-4,
or non-cylindrical, as used in Figure 5.
By the term "non-cylindrical" I understand any section other than round,
for instance rectangular, hexagonal, oval or the like.
Also I will state that although I am aware that the use of a round chimney is
not new, yet the employment of my improved chimney-carrier enables a round
chimney of a much less height to be employed, and in the small space usually
available in bicycle-lanterns and the like, such chimneys have not been employed
in the manner here shown.
My improved round chimney is also adapted for any other burner, but by the
employment of such chimney in a bicycle-lamp with a chimney-carrier such as I
have hereinbefore described, I obtain a very long flame, the horizontal section
of which approximately corresponds to the section of the chimney, in other
words, the flame is not pointed but its upper end forms a straight or annular line
and thus follows the shape of the wick. The colour of said flame is nearly white
and the flame does not smoke or create soot at all, even if it is exposed to an
unusually strong draught, such as bicycle-lamps are often subjected to.
In conclusion I would mention that by means of my improved chimney-carrier
I conduct so much air to the flame, that not only, as herein before indicated, is
an intensive and white flame produced, but also the unpleasant odour hitherto
appertaining to small petroleum-lamps is no longer to any perceptible degree,
present.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is:-
1. In a chimney-carrier for burners of bicycle-lamps or lanterns, the arrange-
ment of ribs or the like attached to the wick-tube of the burner or to the under
portion of the burner, and holding the chimney at approximately the same level
as the burning surface of the wick, the said ribs extending into the interior of the
chimney and affording the air the shortest access to the burner, substantially as
described.
2. In a chimney-carrier for burners of bicycle-lamps or lanterns, the arrange-
ment of ribs or the like upon the said wick-tube, or upon the under portion of
the burner and holding the chimney, which takes into the said ribs at approxi-
mately the same level as the burning surface of the wick, the said ribs affording
the air the shortest access to the burner, substantially as described.
3. In a chimney-carrier for burners of bicycle-lamps or lanterns, the arrange-
ment upon the wick-tubes of an optional number of ribs, attached to the wick-tube
substantially as described.
4. In a chimney-carrier for burners of bicycle-lamps or lanterns, the arrange-
ment of a ring upon the wick-tube at approximately the same level with the
flame, said ring serving as a support for the chimney and mounted in such
manner that an air-tube is formed between the said ring and the wick-tube,
substantially as described.
5. In a bicycle-lamp or lantern, the combination with the burner of a chimney
of considerably reduced height and equal diameter throughout its length, for the
purpose as set forth.
