IMPROVEMENTS IN STORM OR HURRICANE AND OTHER LAMPS OR LANTERNS
Year: 1885

page_text: I EDUARD SOMMERFELD, Lamp Manufacturer, of 33 Skalitzer Strasse in the
City of Berlin and German Empire, do hereby declare the nature of my Invention
for IMPROVEMENTS IN STORM OR HURRICANE AND OTHER LAMPS OR LANTERNS
and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :-
My invention relates to improvements in storm or hurricane and other lamps
or lanterns by means of which the lamp or lantern can be readily ignited or
extinguished without having to remove the glass-In order to attain this object
and at the same time avoid the disadvantages experienced with lamps of similar
kind I employ a two armed forked lever device by means of which the perforated
sieve like glass holder with the glass are raised free of the burner cap so that the
lamp can be readily ignited or the flame extinguished.
The customary telescopic arrangement of the upper part of the lamp which acts
as chimney and is generally used for removing the glass permits this movement
whereas the spiral spring S arranged around the same will act so as to return the
parts to their original position.
Figure 1 is the elevation of a storm or hurricane lamp with my invention applied
to the same and in closed position.
Figure 2 is an elevation of the said lamp or lantern with the glass and sieve like
glass holder raised.
Figure 3 is a horizontal section on the line x x in Figure 1.
Figure 4 is a part elevation of the lamp or lantern partly in section on the line y y
in Figure 1.

glass which rests on the perforated sieve like holder b. c is the burner cap. d are
the air supply tubes which are at the upper end in communication with the
telescopic smoke tube or chimney.
In order to raise the glass a and perforated holder b above the burner cap c
I employ a two armed forked lever g g' h which is arranged to turn around a pin
or pivot which is moveably arranged in a suitable ring e which said ring is
arranged on or around the smoke or hot air tube & whereby the rounded forked
ends g g of the lever embrace or run to the centre of the burner on each side of

the end or arm h of the forked lever g g¹ h is depressed, that the glass holder and
glass are raised above the burner cap c.
The power of the spiral spring S is thus overcome and the glass a, glass holder b
and cover t so raised so as to be free of the burner as shown in Figure 2.
In order to retain the parts in this position without having to continue the hold
on the lever h I affix a small catch i to the smoke or hot air tube d under which
the lever end h is laid.
A slight lateral movement of the lever end h is sufficient to free the lever h from
the catch so that the spiral spring 8 can operate on the parts and press them back
into their original position and thus close the lamp or lantern.
It is evident from the foregoing and the accompanying figures that the device
can be modified in various manners without departing from the tenor of my
invention or instead of employing the forked lever, lever arms can be arranged in
the form of toggle levers to effect the said raising of the glass a and holder 6 or
instead of these arrangements a' rack and pinion device can be employed to like
purpose.
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. The method of moving the parts of storm or hurricane lamps in order to
facilitate the ignition or Textinguishings of the flame by raising the glass a glass
holder b and cover t which said parts are returned to their original closed position
by means of the spiral spring, s substantially as described above and shown in the
accompanying, drawings.
2. A device for raising the glass or glass holder b and cover t of storm or
hurricane lamps consisting of the forked lever g g¹ h ring e and fulcrum i or any
mere modification of the same substantially as described above and shown in the
accompanying drawings.
3. The general construction arrangement and application of my improved device
for facilitating the igniting or extinguishing of the flame in storm or hurricane
lamps' substantially as described above and shown'in the accompanying drawings.
