The present invention relates
lanterns and more speci?cally to improvements of
the burner plate construction including .the
mounting thereof in lanterns of this general type.
In many storm lanterns heretofore known the
are either not connected with the wick tube or
have so slight a connection therewith that the
transfer of the heat from them back to the wick
sured that the storm lantern provided with the
tube and the wick tube together with the burner
plate projected from the ‘interior of the. lower
portion of the lamp. In such constructions the
‘the. outer temperature is high. It must be em-_
phasized that this advantage is obtained by
wick tube together with the burner plate was
often displaced out of its central position during
the manufacture ofthe lamp or during use. and
thus the wick tube no longer'retained its correct
central position in the burner cap.‘ Such dis
15 placement or" the ?ame plate caused the lantern
to burn ine?iciently.
An object of the present invention is to avoid
such defects by- enlarging the burner plate and
constructing it in such manner that it is con
20 stantly in contact with another part of the burner
and‘ thus permanently held in the correct
position. ,
constructed as a simple disc with or without an
upturned edge. The lower part of the burner,
the upper part of the burner or both parts can be
30 employed as a. guide with which the burner or
?ame plate remains in contact in the ?nished
lantern.

The burner or ?ame plate as a whole is indi

poor conductor of heat can? be interposed between cated by a‘ in the embodiment shown in‘Figs. 1 to
the ?ame plate and'the wick tube as described 3 and it is in the form of an inverted bowl which

In addition, the ?ame plate can be provided effected in any other convenient manner. The
lower edge I) of the burner plate a ?ts into the
with apertures which afford a materially im
proved supply of air to the ?ame which. results
45 in a considerably improved burning of the ?ame.
The present invention not only ensures an,
absolutely reliable positioning of the wick tube
and of the ?ame plate as already mentioned, but
as the wick tube is reliably held in the central
50 position it is ensured that the lantern will burn
well in all circumstances. The construction of
the ?ame plate makes it possible to obtain a
better supply of air to the?ame. The resultant
heat can be conducted away from the wick tube

in a reliablemanner by way of the ?ame plate
base or lower part c of the burner in such a >
manner that upper edge 11 embraces the lower 45
part of the ?ame plate.‘ The portion 1‘ is so
shaped and dimensioned that it is embraced by
the burner cap y when the latter-is. slid over the
burner.
'
It is apparent that in this way the burner or
?ame plate, the wick tube e and the wick itself '
are secured centrally in a non-displaceable and
reliable manner.
'
_ In addition tothe usual apertures 70 in the
burner plate, openings h and i are also provided

as shown in Fig. 3.

l
These openings are of con '_ central position of wick tube and burner in a
siderable importance for the proper burning of
the lantern, because they improve the supplyiof
air to the ?ame and thus assist materially in the
proper burning of the lantern.
It is also clearly apparent that the heat gen
erated is transferred with certainty from the wick
tube e to the burner cap g‘ and thus does not
affect the ?ame detrimentally.
simple manner and improves the operation of
the storm lantern while the provision of the large
openings in the burner plate. and the elimination
of the numerous apertures otherwise employed
avoids the formation of undesirable eddies and
gives a very favorable supply of air to the ?ame.
I claim:

inverted bowl-shaped burner or ?ame plate a’ portion of the burner, an inverted bowl-shaped

gap 1 is left between it and the wick tube. In this rounding the upper end of the wick tube and a
embodiment the burner plate surrounds the wick continuous downwardly extending skirt of a rela
15 tube on all sides. The wick tube is reliably pro.» tively large surface-area, a burner cap positioned 15
tected against displacement and the correct cen

m also serves for the reliable transfer from the
wick tube to the burner capof the heat arising
at

burner
plate.

'
'
'
'
If the burner plate is rigidly connected with the
wick tube, then the ?ange m can'be dispensed
with. In this case it is sufficient for the burner
plate itself to be in contact with the burner cap
as this adequately ensures the desired centering of
40
the wick tube and the desired conveyanceof heat
away from the wick tube.
‘
In the embodiment illustrated in Figsi'l' to 9
the apertures is shown in Fig. 3 are dispensed
with; 'It has been found that the openings h’ and
45 i’ are best adapted to supply the necessary airto
the burning ?ame without material detriment'to
the behaviour of the lantern in‘ spite, of thee?j'ect
of shaking and the e?ect of storms. Moreover,
the omission of the apertures 7c enables the eddies
60
otherwise occurring at these apertureswhen the
lantern‘ is exposed to shaking or to a, storm to
be avoided and this also constitutes a material
improvement .over storm lanterns of the'prior
art.
"
In the embodiment shown in Figs. 10 to 12, the
inverted bowl-shaped burner plate a" is extended
down to the wall of the oil reservoir q. The burn
er cap g" is carried on a shoulder of ‘the burner
60
plate a". Theslot'n in the burner cap must be
heldr'in the correct position with reference to the
aperture 0 of the wick tube and this is effected by
interengaging notches p1 and in? as shown in 'Fig.
12 in the" burner cap and burner plate. In this
case the lower part n’ of the burner plate consti
65 tutes the lower part of the burner cap.
This construction of'the burner plate aliords
the advantage, that the heat which is produced
at the burner plate is conveyed directly to the oil
reservoir,_ i. e. is transferred to the component
70 parts of considerable ‘surface’ area'_ and the
heat thus is dissipated in thebest possible man
ner.
I
It will be apparent, therefore," that the ‘di
rnensioning and-shaping of theburner plate in ac:
75 cordance with the invention ensures the requisite
' the wick'tube'to provide a cover for said ?ame
plate. said cap having a downwardly extending
portion‘embracin'g the skirt of said ?ame plate’
whereby a relatively large surface contact is pro

for conducting heat from the plate to the cap.
