Improvements in Gas Ignition Apparatus.
I, ADOLF MARTINI, of 81, Leipzigerstrasse, Berlin, W, in the Empue of Ger-
many, Chemist, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained m and
by the following statement.-
1
This invention relates to improvements in ignition apparatus for use in con-
nection with gas burners whereby the gas upon being turned on 18 capable of
being automatically ignited.
The invention involves the use of porous platinum or other such material
capable of igniting gas on its being directed thereupon, and has for its object to
quickly effect the complete removal of the platinum out of the way of the flame
and heated gases instantly upon ignition being effected.
The invention consists in the provision of a plate upon the top of the chimney
of a burner which plate 18 provided with a hole in which a pillule of platinum is
suspended in such a manner that upon the plate being in position upon the top of
the buiner the platinum shall project through the hole and therefore be imime-
diately above the buiner and in the course of the 18suing gas so that on the gas
impinging upon the pillule the expansion of the gases consequent upon combus-
tion or explosion will immediately force the plate into an upright position in such
a manner that the platinum pillule being vertically suspended will pass entirely
out of line of the flame and issuing gases The invention further consists in
mounting the plate upon a 11m which is perforated and which 18 capable of vel-
tical adjustment upon the top of the chimney so that thereby the upwardly
18suing gases may have fice or restricted egress so as thereby to regulate the
force with which the plate 18 uplifted and maintained in its uplifted position The
invention further consists in the provision of a suspended platinum pillule within
a cential hole provided in a plate of mica or other suitable material which 18
mounted upon an oblique axis and is disposed in an oblique plane immediately
above the chimney of the gas burner so that upon the gas being turned on the
upwardly 188uing gases stike upon the oblique face of the vane plate and foice it
outwardly and out of line with the top of the chimney carrying with it the
platinum pillule that is suspended upon it and maintaining it in that position
while the flame 18 burning.
It will be understood that the plate in each case serves the purpose of a dust
protector to the burner
The invention is illustrated in the accompanying diawings in which:-
Figure 1 illustrates a chimney with a cover plate provided according to the
invention and having a platinum pillule suspended therein for effecting automatic
ignition, while
Figure 2 is a similar view indicating the plate in its upper position after the
flame has been ignited.
Figure 3 is an elevation corresponding to Figure 1 of a modification in which a
flat plate is employed, while
Figure 4 is a corresponding elevation showing the plate in its upper position.

page_text: Figure 5 indicates a partial elevation of a chimney applied with a plate
mounted in a modified manner, while
Figure 6 illustrates the plate removed out of line of the chimney top.
In caying the invention into effect as illustrated in Figures 1 and 2 of the
accompanying drawings a plate d 18 provided of concave form and 18 hinged to a
11m R in such a manner that it shall be partially counter balanced by means of
an aim d' upon which a small counter weight may be provided for the purpose.
The plate de provided with a central hole o within which a platinum pillule P is
suspended from a bracket s On turning on the gas it is immediately ignited and
the force of the explosion effects the movement of the plate d into its upught
position and so the platinum pillule P 18 removed entirely out of line of the
chimney. The force of the explosion on ignition may be reduced or regulated to
quietly effect the upward movement of the plate d by providing the im R with
perforations which can be enlarged or reduced as the im is adjusted The plate d
serves as a dust protecting cap when the lamp is not in use The concave form
of the plate & acts to guide the gas and an mixture through the central hole o.
In canying the invention into effect according to another modification as illus-
ated in Figures 3 and 4 a flat instead of a concave plate O may be provided
which is similarly hinged to a im R and in such a case the plate is preferably of
a laiger size.
In carrying the invention into effect as illustrated in Figures 5 and 6 a plate d
16 provided upon an oblique axis J mounted in a bracket J in tuin mounted upon
the rim R. The plate 16 disposed in an oblique plane to such an extent that
the upwardly issuing gases will effect the removal of the plate out of line with the
chimney and maintain it in that position while the flame is burning In this
case the platinum pillule is similaily suspended within a cential hole in the
plate d and suspended from a brackets provided thereupon
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 18.-
1 Automatic ignition apparatus substantially as hereinbefore described.
2. Means for effecting the automatic ignition of gas consisting of a plate upon
which a platinum pillule is suspended in such a manner that instantly upon
ignition the platinum shall be removed entuely out of the way of the flame sub-
stantially as described.
3. Means for effecting automatic ignition of gas consisting of a plate mounted
upon a chimney provided centially with a hole in which a platinum pillule 18
suspended in such a manner that on ignition the platinum pillule shall be
emoved entuely out of the way of the fame substantially as described.
4 Means for effecting automatic ignition of gas consisting of a plate hinged
to a rim which is mounted upon the chimney, auch plate being partially counter
balanced and being provided with a hole over or in which the platinum pillule is
suspended substantially as herein before described
5 In means for effecting the automatic ignition of gas as hereinbefore specified
the provision of a rim, such as R, with perforations for the purpose substantially
as described.
6 In means for effecting the automatic ignition of gas as hereinbefore specified
the provision of a plate, such as d, of concave form for the purpose and substan-
tially as described.
