1, PAUL HARTZENDORFF, of 97 Alexandrinen 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 in which the light is produced by a candle held
within a shell, and my improvements in lanterns of said kind consist in furnishing
the candle-shell with apertures allowing of the entrance of cool air into, and the
escape of hot air from, said shell.
My improved candle-shell is especially intended for use with small lanterns, for
instance such as are used with cycles, in which there is a great accumulation of heat
within the small space where the flame burns. Owing to this great accumulation of
heat the candle-material melts quicker than corresponds to the consumption of said
material by the flame, and therefore the surplus of the melted material flows down
into the candle-shell, closes the air-supply openings of the same, and impairs in
many cases the proper action of the spring. The object of my invention is to do
away with these drawbacks, and I attain that object by intensely cooling the candle-
shell by means of air, the shell being provided with apertures allowing of the air
passing into and through the shell, as afore mentioned.
In the accompanying drawings Fig. 1 is a front elevation of a carriage lantern
according to my invention, Figs. 2, 3 and 4 being outer elevation, vertical sectional
elevation and plan respectively of the candle shell of same.

form two series or sets, one being located within the burner-casing or body e (Figure 1),
the other outside said casing or body when the parts of the lantern are in their normal
relative position. The outer or lower series a 2 of the air holes is covered by a ring or
piece of tube i hanging down from the bottom of the casing e, and hindering rain or
snow from entering the interior of the shell. I prefer to provide a hole a 3 also in
the bottom of the shell

Improvements in Candle-lamps.
I, PAUL HARTZENDORFF, of 97 Alexandrinen 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:—
This invention refers to lanterns in which the light is produced by a candle held

page_text: within a shell, and my improvements in lanterns of said kind consist in furnishing
the candle-sbell with apertures allowing of the entrance of cool air into, and the escape
of hot air from, said shell.
My improved candle-shell is especially intended for use with small. lanterns, for
instance such, as are used with cycles, in which there is a great accumulation of heat
within the small space where the flame burns; owing to this great accumulation of
heat the candle-material melts quicker than corresponds to the consumption of said
material by the flame, and therefore the surplus of the melted material flows down
into the candle-shell, closes the air-supply openings of the same, and impairs in many
cases the proper action of the spring. The object of my invention is to do away with
these drawbacks, and I attain that object by intensely cooling the candle-shell by
means of air, the shell being provided. with apertures allowing of the air passing into.
and through the shell, as afore mentioned.
In order to make my invention more clear, I refer to the drawing sent in with
provisional application, in which:
Figure 1 is a front elevation of a lantern constructed according to my invention,
Figures 2, 3 & 4 being outer elevation, vertical sectional elevation and plan
respectively of the candle-shell of same.
In the form of construction shown as an example in the accompanying drawing
ȧ is the candle-shell and a' a 2 are the apertures or air-holes of the same. The latter
form two series or sets, one being located within the burner-casing or body e (Figure 1),
the other outside said casing or body when the parts of the lantern are in their normal
relative position. The outer or lower series a 2 of the air holes is covered by a ring
or piece of tube i hanging down from the bottom of the casing e, and hindering rain
or snow from entering the interior of the shell. I prefer to provide a hole a 3 also in
the bottom of the shell a, as shown.
The arrangement afore described affords a complete protection against the candle-
material melting quicker than corresponds to the consumption of said material by the
flame, and in doing away with the drawbacks above mentioned I obtain the advantage
of the candle burning far longer, and the spring of the candle-shell operating far
better, than has been the case heretofore.
Having now particularly described the nature of this invention, and in what manner
the same is to be performed, I declare that what I claim is :-.
1. A candle-shell for lanterns having openings allowing of air entering the interior
of the shell, and cooling the latter as well as the candle, as set forth.
2. A candle-shell for lanterns having lateral openings allowing of air entering the
interior of the shell, and cooling the latter as well as the candle, as set forth.
3. A candle-shell for lanterns having two horizontal series of openings; the upper
series being located inside the casing of the lantern, the lower outside or below said
casing, for the purpose as set forth.
4. A candle-shell for lanterns having two horizontal series of openings; the upper
series being located inside the casing of the lantern, the lower outside or below said
casing, said lower, series being covered by a cap opening downwards, substantially as
described.
