I, FRANZ JUHÁSZ, of 11, Carmerstrasse, Berlin, in the Empire of Germany,
Merchant, do hereby declare the nature of this invention to be as follows;-
-
This invention relates to a device for lighting gas lamps and is intended to
replace and supersede the ordinary means for lighting gas lamps such as
matches, spirit sponges and the like. The device is based on the well known
principle that an igniting ball impregnated with platinum metallic salts (plati-
num black or spongy platinum) when lighting gases (hydrogen or hydro-car-
bons) pass over the same, is caused to glow, and thereby ultimately ignites the
gas with which it comes in contact.
The invention is shown in the accompanying drawings,
Figure 1 being an elevation of the lighter and
Figures 2, 3, 4 and 5 details of the same.
The device consists of a metal cap a to which a curved metal arm bis
attached by rivetting or soldering. At the other end of the arm a metal
holder or socket c is attached, having a fork d (Figure 2) at the top, intended
to open and shut the gas tap.
The cap has a small bell f concentrically arranged in its interior, and in
the top of the inner bell f, a lighting ball or pellet c is mounted by means
of wire or other suitable means.

The lighting pellet consists as usual of a
platinum black or spongy platinum, and surrounded with platinum wire to
better convey heat.
When it is desired to use the device, a handle y is inserted in the socket c,
and the gas tap is turned on by means of the fork d. The cap a is then placed
over the chimney or cylinder of the gas lamp, so that the gas escaping from
the burner encounters the lighting pellet c, the inner bell f serving at the
same time as a collecting device for the illuminating gas, so that the pellet is
lways surrounded by an atmosphere of lighting gas, thus causing a rapid heat-
ng of the pellet.. As soon as the said pellet becomes incandescent, which takes

This invention has the great advantage that by means of the same a very

the heat of the gas flame and the gases of combustion, so that no destruction
the lighting pellet takes place by the vaporising of platinum, which is
ways the case when the igniting pellet remains exposed a long time to the

ing gas by means of matches and the like is entirely excluded.

Improvements in Gas-lighters.
I, FRANZ JUHÁSZ, of 11, Carmerstrasse, Berlin, in the Empire of Germany,
Merchant, 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 a device for lighting gas lamps and is intended to
replace and supersede the ordinary means for lighting gas lamps such as
matches, spirit sponges and the like. The device is based on the well known
principle that an igniting ball impregnated with platinum metallic salts (plati-
num black or spongy platinum) when lighting gases (hydrogen or hydro-car-
bons) pass over the same, is caused to glow, and thereby ultimately ignites the
gas with which it comes in contact.
The invention is shown in the drawings accompanying the Provisional Speci-
fication,
Figure 1 being an elevation of the lighter and
Figures 2, 3, 4 and 5 details of the same.
The device consists of a metal cap a to
which a curved metal arm bis
attached by rivetting or soldering. At the other end of the arm a metal
holder or socket is attached, having a fork d (Figure 2) at the top, intended
to open and shut the gas tap.
The cap a has a small bell f concentrically arranged in its interior, and in
the top of the inner bell f, a lighting ball or pellet c is mounted by means
of wire or other suitable means. The lighting pellet consists as usual of a
porous substance, such as meerschaum, pumice or the like which is saturated with
platinum black or spongy platinum, and surrounded with platinum wire to
better convey heat.
When it is desired to use the device, a handle g is inserted in the socket c,
and the gas tap is turned on by means of the fork d. The cap is then placed
over the chimney or cylinder of the gas lamp, so that the gas escaping from
the burner encounters the lighting pellet c, the inner bell f serving at the
same time as a collecting device for the illuminating gas, so that the pellet is
always surrounded by an atmosphere of lighting gas, thus causing a rapid heat-
ing of the pellet. As soon as the said pellet becomes incandescent, which takes
place in a few seconds, it causes the ignition of the lighting gas, or in other
words produces a gas flame; holes are provided both round the upper surface of
the outer cap and also at the top of the bell in order to afford an easy means
of escape for the gas.
This invention has the great advantage that by means of the same a very
large number of gas lights can be lit without the igniting pellet being exposed
to the heat of the gas flame and the gases of combustion, so that no destruction
of the lighting pellet takes place by the vaporising of platinum, which is
always the case when the igniting pellet remains exposed a long time to the

page_text: intense heat of the gas flame. Further any danger of fire which exists in light-
ing gas by means of matches and the like is entirely excluded.
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. A device for lighting gas lamps consisting of an igniting pellet arranged
at the top of a bell adapted to act as a collecting vessel, the bell being concen-
trically surrounded by a hood and the pellet being held over the cylinder of a
gas flame by means of a handle in such a way that the escaping gas encounters
the igniting pellet and causes the latter to glow so that an automatic ignition
of the gas is produced, substantially as described.
2. The improved gas lighting device constructed and operating as a whole
substantially as described and illustrated in the drawings.
