COMPLETE SPECIFICATION.
Improved Automatic Lighter for Incandescent Gas Lamps.
I, VALENTIN LANDSBERG, Merchant, of 4, Schleswiger-Ufer, Berlin, 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 an automatic gas igniter for incandescent lamps, which
allows of lighting the lamp, without the incandescent body being exposed longer
to the effect of the flame of the automatic lighter, than is necessary and without
tendency for the collection under the incandescent body of air and gas mixture,
which by the explosion effected by the lighting may burst the incandescent body.
The new effect is obtained by use of a system of taps which on opening the main
tap first passes gas to the automatic lighter pipe, but on further and completely
opening of the main tap causes the admission of the gas to the automatic lighter
to be completely closed. Care must be taken, that the automatic lighting tap is
closed shortly after the lighting of the main flame.
In the annexed drawing this new automatic lighter is shown in a front view.
The burner a which is constructed in the known form of incandescent burners,
carries under the tap 6 a branch of any form which is provided with a tap d
and serves for passage of gas to the automatic lighter. For this purpose the
tube is provided at the upper end with a fine escape opening, opposite which
there is arranged a platinum black lighting pill with inserted platinum
The tube c
lighting wire, whereby the pill is fixed on a pill carrier on the tube c.
is quite outside the incandescent body and is placed in such a manner, that the
small flame touches the incandescent body only very little in order to prevent as
much as possible its unequal heating and injury.
!
The tap is provided with a lever the end of which moves in a loop d' of the
tap d, so that the two taps d and bare connected together. Whilst the tap bis
constructed as usual, the tap d has not a round bore, but a somewhat longitudinal
one, which allows the tap d to turn round a certain angle, without the passage
of gas
to the automatic lighter being closed for some time. This position is used
for lighting the automatic lighter and this is effected in the following manner.
On turning slowly the tap b, the tap d turns also and first the admission to the
automatic lighter is opened, whereby in consequence of the longitudinal slot of
the tap d gas passes for a short time to the automatic lighter and makes the
platinum wire of the lighting pill glow and lights the lighting flame. On
continuing to turn the tap 6 further, the admission of the gas to the incandescent
body is opened and lighted. When this is effected, the lighting flame goes out,
as the tube e is closed by the covering of the longitudinal slot in the tap d.
It may also be mentioned that the mechanism for combining the action of the
taps may be of any kind, for instance it may be made very well out of punched
plate. The single parts are further easily detachable, so that exchange can be
quickly effected in case of damage.

page_text: Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is :-
An automatic lighter for incandescent gas lamps, characterized by the connection
of main tap and automatic lighter tap by a sliding guide in such a manner, that
the gas is first admitted for a short time to the automatic lighter before the
main tap is opened whereupon the admission to the automatic lighter is cut off,
for the purpose of preventing the gas from previously entering the incandescent
body.
