PROVISIONAL SPECIFICATION.
Improvements in and relating to Storm Lanterns.
I, EDUARD SOMMERFELD, Lantern Manufacturer of Skalitzerstrasse 33 Berlin,
S.O. in the Empire of Germany do hereby declare the nature of this invention to be
as follows:-
This invention relates to that class of storm lanterns in which a glass shade or
chimney is located between the lamp body and an upper holder connected by a
tubular or other frame to the lamp body.
The first improvement relates to the construction of a wire guard for protecting
the lamp chimney from breakage by an accidental blow. The improved wire guard
consists of two bowed wires one hinged on each side of the upper holder or cap
above the lamp chimney, so that the two arms of wire which constitute each bowed
wire may be folded down to guard the glass chimney and also to serve as a holder for
said chimney by the manner in which said arms are bent to touch the chimney above
and below the projecting flange on the upper end thereof and to curve inwards at
their lower ends to be, each bow, respectively connected to a semicircular piece of
wire adapted to bear against and hold the lower rim of the chimney said semicircular
pieces of wire being adapted to catch or lock together end to end to encircle the base
of the chimney.
The second improvement consists in forming the tubular framework which connects
the cap with the lamp body of extensible telescopic tubes so that the cap may be
raised to a greater distance from the lamp body than it usually is, to enable the
chimney to be easily removed and replaced. The handle by which the lantern is
carried is hinged to the cap and is connected by two linking bars, or by a single wire
bow operating as two linking bars, to the lower members of the tubular extending
frame at such a point on the former that when the handle is folded down the cap is
raised and when the handle is raised the cap is held down in its lowest position.
The perforated guard plate or gallery on which the chimney rests, is fastened
to the burner body by a cylindrical flange in its centre accurately fitting upon a
cylindrical part of the burner cap or flame spreader.

Improvements in and relating to Storm Lanterns.
I EDUARD SOMMERFELD, Lantern Manufacturer of Skalitzerstrasse 33, Berlin
S.O. in the Empire of Germany 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 relates to that class of storm lanterns in which a glass shade or
chimney is located between the lamp body and an upper holder connected by a tubular
or other frame to the lamp body.
The first improvement relates to the construction of a wire guard for protecting
the lamp chimney from breakage by accidental blow. The improved wire guard
consists of two bowed wires one hinged on each side of the upper holder or cap above
the lamp chimney so that the two arms of wire which constitute each bowed wire
may be folded down to guard the glass chimney and also to serve as a holder for
said chimney by the manner in which said arms are bent to touch the chimney above

their lower ends, to be, each bow, respectively connected to a semicircular piece of
wire adapted to bear against and hold the lower rim of the chimney said semicircular
pieces of wire being adapted to catch or lock together end to end to encircle the base
of the chimney. There may be made or fastened on the cap suitable projecting ears
or equivalents for holding up the said wire bows when the latter are folded up from
the chimney.
The second improvement consists in forming the tubular framework which connects
the cap with the lamp body of extensible telescopic tubes so that the cap may be raised
to a greater distance from the lamp body than it usually is to enable the chimney to
be lifted for lighting the lamp or to be easily removed and replaced.
The handle by which the lantern is carried is hinged to the cap and is connected by
two linking bars or by a single wire bow operating as two linking bars, to the lower
members of the tubular extending frame at such a point on the former that when the
handle is folded down the cap is raised and when the handle is raised the cap is held
down in its lowest position.
Or the cap may be raised and lowered by the same swinging movement of the
handle by making the side tubes not extensible but connecting them by a horizontal
arch piece at the top with a central vertical tubular portion of convenient length on or
around which the cap is mounted either direct by a tubular part of said cap sliding
thereon or by the cap being made tubular and sliding on a cylindrical plate acting as
a guide therefor fixed on said arch piece. A spiral spring tends to press the cap
downward from the arch piece and the handle or bail of the lantern is made with a
laterally extending bend or arin which may be provided with an antifriction roller at
its end to run under a cross bar or a peculiarly bent piece of metal strip or wire
fixed to the cap so that on the folding down of the handle or bail, the lateral arm thereon
lifts the cap by pressing upward said strip or cross bar and maintains it raised until
the bail is again moved back into its upright position when the spring aforesaid
presses the cap downward.
The perforated guard plate or gallery on which the chimney rests, is fastened to the
burner body by a cylindrical flange in its centre accurately fitting up a cylindrical
part of the burner cap or flame spreader.
The accompanying drawings illustrate the manner in which this invention is
preferably carried into practice. In the drawings Fig. 1 is a vertical section and
Fig. 2 a side elevation of the improved lantern. Fig. 3 is a side elevation illustrating
the method of releasing the chimney. Fig. 4 is a horizontal section on line A B
Fig. 2. Fig. 5 is a vertical section of a lantern of modified construction. Fig. 6 is
a section through the cap and Fig. 7 is an elevation of the lantern illustrating the
release of the chimney. Fig. 8 is an elevation of the lantern illustrating the raising
of the chimney. Fig. 9 is a plan view of the lantern. Fig. 10 a detail elevation of
the cap. Fig. 11 is an elevation and Fig. 12 a plan view of a modified construction
of the cap. Figs. 13 and 14 are elevations at right angles to each other and partly in
section illustrating the lantern fitted with said cap.
In Figs. 1 to 3 k is the cap, d d the wire bows hinged thereto at a a respectively,
cc being the two semicircular wires to embrace the lower rim r of the glass chimney

Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
In storm lanterns.
1. The combination with a vertically movable cap, of the howed wires d d connected
to said cap, and adapted to support and carry the glass chimney whereby the latter
may be raised and lowered with the movement of the cap.
2. The combination with the cap of the two bowed wires d d hinged at a a to said
cap and the hooking or interlocking parts c carried by said wires and adapted to carry
the glass chimney whereby the latter may be raised and lowered or removed and
replaced substantially as set forth.
3. The combination with the cap and bowed wires d d of the ears el e¹ for supporting
the wires d d in the manner described.
4. The construction of the lantern whereby the downward swinging movement of
the handle or bail causes the lifting of the cap by the action of leverage substantially
as set forth.
5. The combination with the cap of the telescopic tubes fg the handle or bail and
the connecting bars or bow the whole connected substantially as and for the purpose
set forth.
6. The combination with the cap of the tubes g the arch piece g₁ with tubular part
guiding said cup, the spring the handle with lateral arm and the wire or strip m²
or equivalent m² adapted to operate substantially as described.
