"IMPROVEMENTS IN LAMPS, AND IN LIGHTING APPARATUS THEREFOR, SUCH
IMPROVEMENTS BEING APPLICABLE TO POCKET LIGHTS." A communication by
Edward Köhler, Chemist, of Cameny, Silesia.
The object of this Invention is a lamp without using the oil in the liquid form,
usually the case, as well as the combination therewith of a lighting apparatus,
which renders the use of matches unnecessary. This lamp, which is quite harmless
in use, can be used instead of candles and night lights, and with slight modifi-
cation as a pocket light.
The Invention consists in the employment of a cylindrical compartment filled
with a sponge up to a sieve or grating, above which is placed some wadding in
such a position that the wick of the lamp touches it. The sponge is soaked in
benzine or any other combustible volatile carburet of hydrogen, while the cylin-
drical compartment is filled with the same, and the fluid not sucked up by the
sponge then poured off. The lighting apparatus for this lamp consists of a slider,
in which is a turnable case constructed on the well known percussion principle, by
the application of a paper strip with lighting surfaces attached thereto at regular
intervals. This lighting strip is moved forward by a slider round the interspace
of two lighting surfaces, if the case be turned in one direction as the slider is

page_text: turnable on its pin, which is placed on a bracket or arm of the slider, which also
carries the pivot of the case. The slider lifts at the same time the main spring,
while its shoulder slides under the latter, and drops it as soon as the lighting mass
opposite to the point of the mainspring is reached. To light the lamp by this
means it is only necessary to move the slider upwards to its highest position, and
to incline the case towards the burner. A lamp of this kind, with a wick 5mm. long,
and a length of cylinder of 25 cen. by 2 con. diameter, will burn for 12 hours with an
ordinary flame. If used as a night light the flame can be reduced, so that the
lamp will burn much longer. The lamp is quite safe, and can be overturned
without the danger of the fluid escaping. When used as a pocket light the vessel
which holds the sponge is formed like the letter U, the forward sliding of the
wick being effected by a wheel. The construction of the swinging lighting
apparatus is exactly the same as before described.
The case is moved by a knob, which extends through a slit in the case.
Connected with the case is a flat or other spring, which, when the case is brought
into position and released, will drive the case against the burner, thereby exploding
a lighting surface on the paper strip, and lighting the lamp.

"IMPROVEMENTS IN LAMPS, AND IN LIGHTING APPARATUS THEREFOR, SUCH
IMPROVEMENTS BEING APPLICABLE TO POCKET LIGHTS." A communication by
Edward Köhler, Chemist, of Cameny, Silesia.
The object of this Invention is the combination of a lamp without liquid oil,
with a lighting apparatus, whereby the use of matches is rendered unnecessary.
The improved lamp is entirely free from danger, and can be used in lieu of
candles or night lights, for carriage lanterns, and other purposes. It is also with
slight modifications practicable as pocket tinder boxes.
On the annexed Drawing Figure 1 shows the lamp in the form of a candle;
Figure 2 a longitudinal section, and Figure 3 a cross section thereof.
The case a is filled with a sponge as high as a sieve or grating b, above which is
placed some wadding in such a manner that the wick of the burner & comes in
contact with it. The sponge is soaked with benzine or other burnable volatile
carburetted hydrogen by filling the case a with the same, and pouring off the
fluid not soaked in by the sponge.
The lighting apparatus for this lamp consists of a slider f, to which the turnable
case g is attached. This case g is constructed on the principle of the well known
percussion lighting boxes, in which paper strips h are used, provided at regular
intervals with inflammable striking masses. On turning the case g in the direction
of the arrow, Figure 1, this kindling strip h will be moved forward by a slider ¿
round the interspace of two lighting masses, the slider i being turnable round a
pin o fixed on the arm of the slider f, which carries also the pivot of the case g.
The slider ȧ effects at the same time the lifting of the main spring m by sliding
under it with its shoulder n, dropping it again as soon as the lighting masses are
brought opposite the point of the main spring m. To light the lamp therefore it
is only necessary to raise the slider f, and to incline the case g towards the burner,
as shown in Figure 2. Such a lamp with a wick 5 mm. thick in a cylinder of
25 cm. long and 2 cm. diameter, will burn with an ordinary flame for about
12 hours. As a night light the flame may be much smaller, and the lamp conse-
quently burn much longer. The lamp is completely free from danger, and can be
upset without fear of spilling the fluid. In certain cases it is advisable to fill tho
case a with a movable sponge, and to arrange the percussion tinder box for lighting
turnable in the cage carrying the lamp. This modification is very useful for
carriage lanterns. As shown by Figure 4, the case a is fixed in the tube m of the
lantern, and lifted therein by a spring o. By means of a button p it can be pulled
down, whereupon by the small drawing rod r, which connects the upper part of
the case with the percussion tinder box turnable round 8, the latter is brought into
the dotted position, and the lighting is effected. The rod r, for inclining the tinder
box towards the wick, may also be used for the arrangement in Figure 1. In
Figures 5, 6, and 7, which show the lamp used as a pocket tinder box, the case to
hold the sponge soaked with benzine has a U form, the sliding of the wick being
produced by a little wheel 8. The construction of the swinging lighting apparatus
is exactly the same as in Figure 1. The case g, which receives it, is moved by the
button 7, which extends through a slit of the case. To the case ga pendulum or
flat spring can be applied, this spring being in tension. When the case g is
brought into the dotted position, and on releasing the case g, it is driven auto-
matically against the burner, thereby exploding one of the lighting masses on the

page_text: paper strip h, and lighting the lamp. A modified arrangement of the case for
receiving the sponge and lighting apparatus is shown in Figures 8 and 9, Figure 8
being a plan or opened view of a pocket lighting box, and Figure 9 a section of the
same on line A, B, in Figure 8. The box a is by a division wall b divided into
two parts, one of which d is for receiving the sponge. The latter can be fitted
from the top into the box a after moving back the cover f, which is connected with
the back wall of the box. In the left half of the box a the lighting apparatus is
arranged, which consists of the main spring g, the fixed plate h, the slider m, the
valve p, and the pin i for receiving the paper strips. The slider m is mounted on
the pin i, and is provided at its bottom end with a pin o, which catches in the
slit of a plate connected with the valve p. On bringing the valve p into the
dotted position the slider m is moved downwards, so that its shoulder n catches
under the main spring g. By the upward movement of the slider m this shoulder n
lifts the spring, and actuates at the same time the lighting strips in the usual
manner. As a lighting mass of this strip arrives opposite the end point of the
spring g, this slips from the shoulder n of the slider, and strikes in the usual
manner against the lighting mass of the strip, thereby lighting the wick of the
burner by the flame produced. By the opening of the cover the inside of the
tinder box is admissible for taking out the case, and setting in the lighting
strips.
Having now described and particularly ascertained the nature of the said
Invention, and the manner in which the same is or may be used or carried into
effect, I would observe in conclusion that what I claim as my Invention is,-
1. The construction and use of a lamp in candle form, having a sponge soaked
with benzine or other burnable volatile carburretted hydrogen, in combination with
a lighting apparatus consisting of a movable percussion tinder box, substantially
as hereinbefore described and illustrated by the accompanying Drawing.
2. The combination and use of the lamp with the percussion lighting apparatus
for a pocket tinder box, substantially as herein before described and illustrated by
the accompanying Drawing.
3. The combination of the swinging percussion lighting apparatus with the

purpose hereinbefore described and illustrated by Figure 4 on the accompanying
Drawing.
4. The connection of the movable swinging percussion lighter with the fixed lamp
case by the rod r, for the purpose of bringing the lighter automatically inclined
towards the wick, substantially as heroinbefore described and illustrated by Figure 4

5. In a pocket tinder box the arrangement of the removable case a, which contains
the sponge soaked with volatile carburet of hydrogen, substantially as hereinbefore
described and illustrated by the accompanying Drawing.
6. In a pocket tinder box the combination of the lighting arrangement, con-
sisting of main spring g, plate h, slider m, with shoulder n, valve p, and lighting
