Improvements in and connected with Automatic Gas Ignition
Apparatus for Lamps.
We, OSCAR SARKANDER, of 13, Prinzen Strasse, Berlin, Kingdom of Prussia,
erman Empire, Manufacturer, and WILHELM BRAUN, of 21, Chaussee Strasse,
ross-Lichterfelde, near Berlin aforesaid, Merchant, do hereby declare the
ature of this invention, and in what manner the same is to be performed, to
e particularly described and ascertained in and by the following statement:
The present application relates to an automatic gas ignition apparatus in
hich the igniting pellet is not located vertically above the burner but a part
f the gas stream is guided in such manner as to meet the pellet which is fixed
o a gallery mounted upon the chimney of the lamp.
The chief feature of my invention is that the pellet need not be moved away
when the gas is ignited as it was necessary with the constructions hitherto
employed.
In order to make my invention more clear, we beg to refer to the accompany-
ing drawing, in which:
Figure 1 is a vertical section through my improved device.
Figure 2 is a top view of the same,
Figure 3 illustrates the guide for concentrating the gas stream.
Figure 4 illustrates the attachment of the ignition pellet.
In the drawing a is a gallery mounted upon the chimney of the lamp and
carrying cone b. This cone 6 is provided with perforations except at the part
indicated by the letter c. To the upper part of the cone b a small guide f is fixed
in such manner as to concentrate the gas stream and to direct the same to a
certain place. In face of the mouth of this guide f the igniting pellet d is suit-
suspended to a cross rod e by means of
ably arranged. This igniting pellet
three platinum wires.
The manner of suspension of the igniting pellet clearly can be seen from
Figures 1 & 4; Figure 2 distinctly indicates the place of the ignition pellet upon
the unperforated part of the cone b.
When the burner is opened, the gas rises within the chimney, enters the small
0 guide f and at the end thereof meets the ignition pellet which then effects the
ignition of the gas. The important advantage of this ignition apparatus with
respect to apparatus hitherto employed is that the pellet can be used for a long
time owing to the fact that the hot gases do not directly meet the pellet and
destroy its capacity of igniting.

Hitherto the pellets had to be moved away when the lamp was ignited and
sensible mechanisms were necessary to effect this movement. In our application
the pellet is fixed at one place and in spite thereof is protected against the hea
of the flame by the unperforated part of the cone b.
Having now particularly described and ascertained the nature of our sai
40 invention, and in what manner the same is to be performed, we declare that wha
we claim is:-
atigas ignition apparatus, the combination with a gallery (

page_text: fixed upon the chimney of the burner, a cone (b) carried by said gallery and
being open at its top, having perforated side-walls except a small part (c), a
guide (f) fixed to the top of the cone (b) concentrating the stream of the gas, an
igniting pellet (d) suitably arranged in face of the mouth of the guide (f) and
fixed to a cross rod (e) by means of platinum wires, substantially and for the 5
purpose as described.
