STORM LANTERN
‘Bruno Nier, Beierfeld, Germany
Application June 5, 1936, Serial No. 83,749
In Germany June 6, 1935
5 Claims.
It is known, that storm lanterns of normal
construction, more particularly those with a re
duced combustion space per Hefner candle power,
(Cl. 67—53)
forms of the invention are illustrated by way of
example,
Fig. 1 is a longitudinal sectional view showing
one side of the burner;
Fig. 2 is a sectional view taken at a right angle 01
even if they function satisfactorily at the outside
5 temperatures prevailing in a temperate climate,
will fail when used in hot regions.
The applicant has found, that this disad
vantage may be overcome, if the wick sheath
burner plate shown in Fig. 1;
be made of a material which is a good heat con
10 ductor, more particularly of copper. In this
insulating material;
way storm lanterns can be produced, which burn
in a satisfactory manner independently of the
outside temperature. The manufacture of the
wick sheath from copper and similar materials
" entails a certain increase in the cost of the lan
tern and the applicant has therefore sought,
while using the usual materials, more particu
larly tinned sheet iron, for the wick sheath as
well, to produce storm lanterns which will burn
20 satisfactorily in all circumstances. It has been
found that the so-called ?ame plate of the storm
lantern burner, which in the known construc
tions is connected to the wick sheath, transmits
the heat developed, when the lantern is burning,
25 to the wick sheath itself and is thus the cause
of the lanterns no longer burning in a satisfac
tory manner at higher outside temperatures.
It was found, that the observed disadvan
tages disappear, when the ?ame plate is quite
30 unconnected with the wick sheath and between
the inner edge of the ?ame plate and the upper
end of the wick sheath an air gap of su?icient
size is provided, by which the heat transmission
from the ?ame plate to the wick sheath is pre
35 vented.
For this reason according to the invention the
?ame plate is ‘completely insulated from the up
per edge of the wick sheath and is connected
with some other part of the burner or some
40 other part of the wick sheath, preferably with
the lower part of the burner, and in some way
held securely in this position.
The intermediate air space between the inner
edge of the ?ame plate and the upper end of
the wick sheath, may according to a further
modi?cation of the invention be replaced by an
intermediate piece of heat-insulating material,
which separates the ?ame plate from the wick
sheath and establishes its connection with the
wick sheath.
Finally it is also possible to make the ?ame
plate entirely of heat insulating material, there
by also effectively preventing the transmission of
heat from the ?ame plate back to the wick sheath.
In the accompanying drawing constructional
55
to Fig. 1;
Fig. 3 is a top plan view of wick sheath and
Fig. 4 shows a burner with a ?ame plate of
10
Fig. 5 is a sectional view through the wick
sheath and ?ame plate shown in Fig. 4;
Fig. 6 is a top plan view of Fig. 5;
Fig. 7 is a section through the wick sheath and
?ame plate of a third embodiment;
Fig. 8 is a top plan view of Fig. 7.
The burner consists of the lower burner part
I , the burner cap 2, and the wick sheath 3, which
are formed in the usual manner. 4 is the ?ame
plate. This plate is no longer directly connected
in contacting relation in the known manner with
the upper part of the wick sheath 3, but is ?xed
by the bridge pieces 5 to a lower part of the
burner. In this way there is formed between the
upper end of the wick sheath 3 and the ?ame
plate {3 an air space 6, by which the direct heat
transmission from the ?ame plate to the wick
sheath and vice versa is prevented.
In the constructional form of Figs. 4 to 6 the
?ame plate 4’ is made of heat insulating mate 30
rial. Material of this kind of the most varied
sort in pressed or rolled form, such as asbestos,
asbestos mixed with arti?cial resin, ?bre or the
like, may be used.
'
In the constructional form shown in Figs. 7
and 8 the ?ame plate 4” made of metal is sep
arated from the wick sheath by an intermediate
ring 'I of insulating material, and by these means
as well transmission of the heat from the ?ame
plate 4" back to the wick sheath 3 is prevented 40
to a su?icient degree.
The connection between the parts 4 and 3
may be established in any suitable manner, for
instance by beading, folding or the like. This
forms no part of the invention, for which it is 45
only essential that transmission of the heat from
the ?ame plate back to the wick sheath and the
consequent disturbances, when the storm lantern
is burning are eliminated.
Experiments have shown that a lantern con 50
structed in this way will burn absolutely satis
factorily at all outside temperatures in which
a lantern might be used. It is therefore no longer
necessary to make the wick sheath of copper,
and the entire burner may be made in the usual 55

What I claim is:
1. A storm lantern burner comprising in com
the wick sheath with an air gap and bridge pieces
for connecting the flame plate with the lower
part of the burner and for maintaining the ?ame
plate in substantially the plane of the upper edge
bination a burner cap, a Wick sheath disposed
within the burner ‘cap, a ?ame plate mounted so
as to surround the wick sheath at a point sub
of the sheath.
4. A storm lantern burner comprising in com
bination a burner cap, a wick sheath disposed
way of sheet iron and the entire lantern may be
made of sheet iron.
'
stantially ?ush with the upper edge thereof and
means for heat-insulating the ?ame plate from
10 the wick sheath.
2. A storm lantern burner comprising in com
bination a burner cap, a wick sheath disposed
within the burner cap and. a ?ame plate mounted
so as to surround the wick sheath with an air
gap between the two.
v
3. A storm lantern burner comprising in com
bination a burner cap, a wick sheath disposed
within the burner cap, a ?ame plate surrounding
within the burner cap, a metallic ?ame plate sur
rounding the wick sheath and a ring-shaped wall
of insulating material interposed between the 10
?ame plate and the wick sheath for‘?xing the
?ame plate to the wick sheath.
5. A storm lantern burner comprising in com
bination a burner cap, a wick sheath disposed
within the burner cap and a ?ame plate of heat 15
insulating material mounted on the wick sheath.
