Improvements in Storm Lanterns.
I, EDUARD SOMMERFELD, of Skalitzerstrasse 33, Berlin, in the Empire of
Germany, Manufacturer, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
The present improvements in storm lanterns consists in fastening the air
introduction pipes on to the combustible receiver in such a simple but solid
manner, that the device for lifting the lantern glass arranged on the upper part
of the said air introduction pipes, can be operated without fear of endangering
the points of connection between the receiver and air pipes. Further the
actuating handle for raising the glass operates when moved to either side of the
lantern which necessitates especial care with regard to the manner of fastening
the air-introduction pipe to the receiver; and also the construction of the said
device for lifting the glass must not have a harmful effect to the said points of
connection,
The annexed drawing illustrates the improved storm lantern, in which
Fig. I is a front view.
Fig. II is a side view showing the protection glass lifted.
Fig. III a different form of fastener for the device for lifting the glass.
In Fig. I it can be seen that that the combustible receiver a is recessed or shaped
so as to conform to the outline of the air-introduction pipes which are soldered
to it so that an entirely reliable connection is made. A more solid fastening is
thus obtained than in soldering the air-introduction pipes simply on to the com-
bustible receiver or in weakening the latter by cutting away parts which is done
very often.
The frame e for protecting the glass is secured in the known manner on the
air-introduction pipes whilst the device for lifting and holding the glass in the
lifted position in an absolutely reliable manner is fastened on the upper part of
the air introduction pipes. By the present construction the protection glass is lifted
by turning the handled to the one or the other side of the lantern instead of being
lifted and fixed by turning the handle to one side only, which latter con-
struction has the disadvantage that if not properly manipulated the action of the
mechanism may be injured and more especially the points of connection suffer,
which disadvantages are avoided by the device shown in the examples repre-
sented.
This device is arranged as follows:--
The handle has two suitable symmetrical indentations allowing its bearing
at f and also its turning. By a further V shaped indentation i of the handled
the lifting of the protection glass is effected. For this purpose the plate k of the
frame e which supports the glass is connected with a wire bow which has a
peculiar form as represented in Fig. II. The before mentioned V shaped
indentation i of the handle d lies underneath the wire bow so that at the lowest

page_text: position of the said wire bow / there is sufficient room between it and the inden-
tation of the handled to enable the lantern to swing when carried, so as to
retain its perpendicular position.
The frame e supporting the glass has the necessary guides for its lifting, and
the plate is provided with a socket m which can slide up and down on the
cylindrical air-introduction tube n. The frame is held down on the burner socket
in the known manner by a spiral spring o. In order to diminish the friction
between the V shaped indentation of the handled and the wire bow as much
as possible a roller is preferably arranged on the said ✓ shaped indenta-
tion i.
The lifting of the frame supporting the glass for lighting or cleaning purposes
is done by simply depressing the handle d to the one or other side. The roller p
and consequently the part of the handle is thus first forced into one of the
sidewardly bent parts 7 of the wire bow in order to take the position shown in
Fig. II when the handle is still further pushed down, in which position it is held
by the bends r. In this manner the lifting of the frame carrying the glass is
rendered possible without fear of bending any of the parts by wrong manipu-
lation and without fear of breaking at the points of connection.
In Fig. III the desired purpose is obtained in another manner. The handle d
is mounted at f in a vertical cylindrical body g fastened to the air-introduction
pipes connected with the plate an exterior cylinders is arranged, which
follows the movements of the frame c when the handle d is turned, for which
purpose it must be provided at the sides with suitable slots in order to make the
required liberty of movement possible. On the cylinders a cover t is arranged
which closes the top end. This arrangement has the advantage that the parts
moved are protected from exterior influence.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is:-
1. An improved storm lantern in which the air introduction pipes bare
fastened on the combustible receiver a by means of recesses arranged in the
receiver in which the air introduction pipes are arranged and soldered to the
receiver so that the spots which are most endangered when the lifting device for
the glass is operated possess sufficient resistance against injuries.
2. In the improved storm lantern for preventing useless strain of the connection
described in Claim I between the air introduction tubes and the receiver a,
a device for lifting the protection glass in which the handle d of the lantern
which is provided with a V shaped indentation i, engages under a wire bow
provided on both sides with symmetrical bends q and so that the lifting of the
frame e carrying the glass and connected to the wire bow, and the holding of the
same in the raised position are rendered possible by turning the handle d towards
either side of the lantern.
