Improvements in Gas Lamps.
I, RUDOLPH GROSCH of Weimar, Germany, Gentleman, do hereby declare the
nature of this invention to be as follows:-
This invention relates to apparatus for lighting lamps having one, two, or more
incandescent burners, such that on raising a flap or valve that serves to close the
bottom of the lamp, there are opened simultaneously the gas tap for the igniting
apparatus and the main gas tap for the incandescent burner or burners, so that the
ignition of the flame of the igniting-apparatus at once effects an ignition of the gas
in the incandescent burner, the arrangement being such that on the removal of the
lighting lamp from the incandescent lamp, the gas tap for the igniting-apparatus
is shut again automatically.

single incandescent burner combined with lighting apparatus according to this
invention, and
Fig. 2 illustrates the connection of the lighting apparatus with the main
gas tap.
Fig. 3 represents in plan an arrangement suitable for two incandescent burners
situated side by side, and Fig. 4 is a similar view of an arrangement for a street
lamp with three incandescent burners.
Froin the gas pipe A below the main gas tap B, there branches off a tubular
union C, the elbow part D of which contains the plug a of the tap of the igniting
apparatus.
The lighting apparatus is provided above the tap-plug a with a nozzle d having
air inlet holes and a pipe e terminating in an igniting tube f, which is slotted at
and is provided at its rear with an igniting aperture 2. The front end of this
tube carries a "running flame tube" g which is likewise outwardly slotted and
leads to the incandescent burner i.
The tap plug a is connected by an arm k with a flap or valve 6 which is arranged
over the lighting aperture in the bottom of the lamp casing Z and serves to close
the said aperture. This bottom flap & must be pushed up by the igniting lantern
when it is desired to ignite the gas of the igniting apparatus at the hole of the
igniting tube f.
The main gas tap B is connected to a double-armed lever h¹, h. The arm h¹
bears upon the tap b and is related by the latter, which consequently operates the
main gas tap B. The arm h is provided with an arm which can be pushed up by
the person putting out the lamp, by means of a suitable rod.
The mode of operation of the apparatus is as follows:-

Lamps.
I, RUDOLPH GROSCH, of Weimar, Germany, Gentleman, 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 apparatus for lighting lamps having one, two, or more
incandescent burners, such that on raising a flap or valve that serves to close the
hottom of the lamp, there are opened simultaneously the gas-tap for the igniting
apparatus and the main gas tap for the incandescent burner or burners, so that the
ignition of the flame of the igniting-apparatus at once effects an ignition of the gas
delivered to the incandescent burner or burners the arrangement being such that
on the removal of the lighting-lantern from the incandescent lamp, the gas tap for
the igniting-apparatus is shut again automatically.
Fig. 1 of the drawings filed with my Provisional Specification is a longitudinal
section representing a single incandescent burner combined with lighting-apparatus
according to this invention, and
Fig. 2 illustrates the connection of the lighting-apparatus with the main
gas-tap.
Fig. 3 represents in plan an arrangement suitable for two incandescent burners
situated side by side, and Fig. 4 is a similar view of an arrangement for a street-
lamp with three incandescent burners.
From the gas-pipe A below the main gas-tap B, there branches off a tubular
union C, the elbow part D of which contains the plug a of the tap of the igniting-
apparatus.
The igniting apparatus is provided above the tap-plug a with a nozzle d having.
air inlet holes and a pipe e terminating in an igniting-tube f, which is slotted at f
and is provided at its rear with an igniting-aperture 2. The front end of this
tube carries a "running-flame tube" 9 which is likewise outwardly slotted and
leads to the incandescent burner i.
g
The tap-plug a is connected by an arm k with a flap or valve b, which is arranged
over the lighting-aperture c in the bottom of the lamp-casing Z and serves to close
the said aperture. This bottom flap b must be pushed up by the igniting lantern
when it is desired to ignite the gas of the igniting-apparatus at the hole of the
igniting-tube f.

page_text: The main gas-tap B is connected to a double-armed lever h¹h. The arm bears
upon the flap band is rotated by the latter which consequently operates the main
gas-tap B. The arm h is provided with an arm / which can be pushed up by the
person putting-out the lamp, by means of a suitable rod.
The mode of operation of the apparatus is as follows:-
When the lamp-lighter pushes up the flap 6 with his igniting-lantern, the arm k
rotates the plug a and the gas flows through the tube e (drawing in air at the same
time by means of the nozzle d) to the igniting-tube f and the "running-flame-
tube" g, and is ignited at the opening f of the igniting-tube f by the igniting..
lantern.
The pushing up of the flap b also raises the arm h¹ and thereby opens the main
gas tap B, so that the illuminating gas can pass to the incandescent burner i with
the result that the igniting-flame, issuing from the tube g, ignites the gas, and the.
mantle of the burner is rendered incandescent.
If, now, the igniting-lantern be withdrawn through the aperture c, the flap 6 will
fall, in consequence of its own weight, and close the aperture c. The effect of this.
will be to turn the plug a so that no more gas can flow to the igniting-flame. But
the main gas tap B will remain open, because its arm h¹ will not be affected by the
downward movement of the flap b.
When the lamp is to be extinguished, the arm is pushed up until the arm
comes into contact with the flap b, whereby the main gas-tap B is closed and the
lever his moved into such a position that when the flap is again pushed up,.
the main gas-tap B will be opened anew.
b
In adapting apparatus of this kind for lighting a lamp having two, three, or more
incandescent burners supplied with gas from the same pipe, all that is necessary,
as shown in Figs. 3 and 4, is that the igniting tube be provided with a corre-
sponding number of unions which are slotted at the top and each of which
terminates in an outwardly slotted and suitably placed small iguiting-tube g.
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. In a gas lamp having one, two, or more incandescent burners an igniting
apparatus wherein the gas supply pipe A is provided below the main gas-tap B with
a branch igniting pipe having in connection therewith a slotted rearwardly open
igniting-tube fa "running-flame tube "g, a tap a connected with a flap or valve b
that normally closes an opening in the bottom of the lamp casing, and the valve B
is provided with a double armed lever having a depending part 1, the
arrangement being such that on pushing up the flap or valve 6 the taps a and B.
will be opened, the tap a being closed automatically when the flap or valve bis
allowed to fall, and the tap B being closed by pulling the part attached to the
lever, substantially as herein described.
2. My improved gas-lamp igniting apparatus constructed, arranged, and operating
as hereinbefore described with reference to and shown in Figs. 1 and 2 of the
drawings referred to and as modified according to Fig. 3 and to Fig. 4 thereof.
