Improvements in or relating to Incandescence Gas Burners with
Automatic Ignition Devices therefor.
I, HERMANN BURKERT, Merchant, of 15, Brunnenstrasse, 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:-
The present invention relates to improvements in incandescence gas burners
with automatic ignition devices therefor, in which an ignition-ball is provided
with platinum wires or the like in proximity to the burner in order to insure
ignition of the gas when turned on.
In the automatic gas igniters of this kind hitherto known there has been this
drawback that in consequence of the want of a sufficient supply of oxygen igni-
tion did not take place with certainty, the balls of platinum black or like
material in consequence very soon refused to act, did not ignite and had to be
replaced by new ones. These drawbacks are to be overcome by the present
invention. The accompanying drawing shows two forms of construction of
incandescence gas burners with automatic gas ignition devices consisting of an
ignition ball and depending platinum-wires.
The principal feature of the invention consists in the ball with its platinum-
wires being arranged directly over the burner and it is advisable to make the
ball support and the support rod for the incandescence mantle or body of suffi-
ciently fire-proof material such as fire-clay, soap-stone, magnesia, infusorial earth.
or like materials or compounds and to keep the ball with the platinum-wires
cool by a suitable supply of air.
Figs. 1 and 2 represent a burner-head for incandescence gas-lighting, viz:
Figure 1 for a central, and
Figure 2 for a lateral suspension rod for the mantle. The air is conducted
through tubes or passages a a leading from both sides of the burner upwards
and meeting in the central tube or opening which ends in an enlargement
or chamber d at the upper part of the burner head c and as the ball f with its
platinum or like wires g is arranged in or directly above this enlargement or
chamber both are continuously cooled by the air flowing towards them and are
thus provided with a sufficient supply of oxygen.
The gas and air mixing device in the burner-head is not further shown as
it forms no part of the essence of the invention. By means of the air supply
described it is impossible for the igniting-device to fail to act and automatic
ignition balls of this description will last much longer than ordinary devices
of a somewhat similar kind.
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. An automatic ignition device for incandescence gas burners comprising a
burner provided with an air-supply conduit, and a platinum black or like auto-

page_text: matic ignition ball with depending platinum wires arranged above the burner-
head and air supply in such manner that the ignition device is cooled by the
air flowing towards it and is fed with oxygen substantially as described.
2. An incandescence gas burner with automatic ignition device comprising a
burner with upwardly inclined air supply passages meeting in a central chamber
at the top of the burner head, and a platinum black or like automatic ignition ball
above said central chamber,, substantially as described.
3. An incandescence gas burner with automatic ignition device substantially
as described or illustrated in the accompanying drawings.
