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 the object of which is to enable the said lamp or lantern to be ignited
or extinguished with facility without having to remove the glass.
I am aware that several attempts have been made to attain the same object such
as raising the glass with the deflector, cutting a central opening through the glass,
setting the glass on a sheet metal cylinder which is provided with a suitable
opening and a slide and others but all of these devices are either too expensive for
wholesale manufacture or give too much shade.
According to my said invention all these difficulties are overcome.
Figure 1 of the accompanying drawings is the elevation of a hurricane or storm
lantern with closed igniting opening.
Figure 2 is a like elevation with the igniting opening free.
Figure 3 represents the oil vessel and burner in elevation and the glass and the
perforated glass holder or sieve in section.
Figure 4 is a top view of the perforated glass holder or sieve showing the
position of the burner cap and my improved device for covering the opening in
the lower annular flange of the glass.
The lower annular part a of the glass b which rests on the perforated or sieve
like disc c, the outer edge of which is so raised up that it forms a guide to prevent
the said glasses b leaving the aforesaid disc c, is cut away in appropriate inanner
at d so that a match or other burning object can be inserted into the lamp or
passed through this said opening in order to be able to light the wick readily.
A small bridge e is soldered or otherwise attached to the sieve or perforated glass
holder and is a trifle shorter than the opening d in the lower annular flange of the
glass so that the said glass fits over the said bridge and is thus so held in correct
position that the said glass cannot be turned round independent of the closing
device for the said opening d and the glass holder c.

page_text: A flapfof suitable form is now hinged in suitable manner to the said bridge e
by means of a small flat spring h which is rivetted or otherwise attached to the
under side of the bridge and presses against a protruding part i of the hinge or
another kind of spring for instance a spiral spring wound around the pin to the
said hinge g can be employed without departing from the tenor of my said
invention.
In order to enable the said flap f to be readily opened two small lugs & can be
pressed or turned up one on each side of the said flap or only one such said lug
can be employed or a small knob can be affixed to the said flapf for the like
purpose of readily opening and closing the same over the opening d in the lower
annular flange of the glass.
It is evident that when the flap f is closed and the glass and sieve like glass
holder c turned so that the flap & lies immediately within one of the hot air
conducting tubes a ẞ that the illuminating effect of the lamp or lantern will be in
no way effected as the entire surface of the lower flange to the glass with the
exception of those parts covered by the said hot air conducting tubes or arins
is left free so that the light from the burner can stream unimpeded through the
same.
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-In storm or hurricane lamps or lanterns the arrangement application and
employment of the flap f which is so arranged that the same can make a limited
movement around the hinge g for itself alone and in combination with the bridge c
fixed to the sieve like holder c for the glass by means of which said bridge the
glass is so held in position on the holder c that the said glass cannot be turned
independent of the said holder c or any mere modification of the said arrangement
substantially as and for the purpose described and shown in the accompanying
drawings.
2-The arrangement and application of the spring or its equivalent and the
projection on the hinge g in order to retain the flap fin closed or opened position
and to limit the movement of the said flap ƒ for itself and in combination with the
opening or cut d in the lower flange of the glass or any mere modification of
the same substantially as described and shown in the accompanying drawings.
3-In storm or hurricane lamps the general arrangement, application and
combination of the parts to facilitate the igniting or extinguishing of the lamp
substantially as described in the foregoing specification and shown in the accom-
panying drawings.
