1 Claim.
(Cl. 200—-53)
This invention relates to an automatic light
ing means for gas or gasoline stoves.
It is aimed to provide a novel construction
wherein the gas will be ignited automatically
5 upon opening the supply valve and a construction
wherein the same system may be utilized for
operating a number of burners, so that a single
source of electrical energy will suf?ce.
The more speci?c objects and advantages will
10 become apparent from a consideration of the description following taken in connection with ac
companying drawing illustrating an operative
embodiment.
In said drawing:-—
Figure 1 is a View showing my improved system
or mechanism in connection with a gas burner;
the house lighting current or a storage battery,
the latter being suggested at 33. A conductor 34
leads from one terminal thereof to a conventional 15
spark coil 35 having breaker points 36.
Said con

of the battery and is grounded to the burner or
other metallic parts, for instance the support 25.
Another conductor 39 leads from the secondary
of the coil 35 to a contact 40.

erably being fastened to the insulation by means
of nuts 29 and 30 and being removably and ad
justably fastened in place by means of a cleat
3i disposed over the body 28 and fastened to the
support 25 by means of screws 32, it being realized
that the support 25 and cleat 3| are notched or
cut away to conform to the shape of the body 28.
By reason of this construction, the spark plug
may be readily removed and the electrodes may
10
be removed, adjusted or replaced.
The electric energy for operating the plug may
be supplied from any suitable source, for instance
Figure 3 is a detail section taken on the line
3—3 of Figure 2, and
Figure 4 is a detail section taken on the line
43-4 of Figure 1.
Referring speci?cally to the drawing wherein
like reference characters designate like or simi
lar parts, Ill designates a conventional burner as
is used on a gas stove or gasoline stove and I! is
the supply conduit through which the fuel is
passed thereto. An elongated rod [2 has a valve

Slide 2! has a lateral arm 4| from which a post
42 of insulation rises and which post carries a
switch conductor 43 and an upper conductor 44,
respectively engageable with the contacts 3? and
Ail.
When the device is operated from the off posi

the battery to the coil and spark plug, since the 7
contacts 453 and 37 engage and the contacts 4!} and

latter to the electrode 21. The electrode 26 is
preferably removably held in place by a screw 46

the other end. Slide 21 is square and slidably
and non-rotatably mounted in a square opening
of a guide or bracket 16a connected to the stove.
The gas or fuel issuing from the ori?ces 23 of
the burner is adapted to be ignited by an electric
3.1 spark produced from a plug means at 24. Such
plug means may comprise an angular metallic
support 25 extending from the burner and carry~

electrode 21 carried by a porcelain or other insu

It will be realized, that the circuit
will open as soon as the handle i3 is released be
cause of the expansive action of spring 22.
With
the present type of switch and circuit, having the
breaker points, as many burners as desired may
be connected in the circuit and operated from the
one coil and from the same source of electric

energy.
Various changes may be resorted to provided
they fall within the spirit and scope of the in
vention,

in cross section, guide means having an opening
occupied by the slide and corresponding to its
polygonal shape, an operating sleeve engaging
one side of the slide, said sleeve being slidably
mounted on the rod, a pin and slot connection
between the sleeve and rod whereby operation of
the sleeve will turn the rod relatively to said slide,
a spring surrounding the rod at the opposite side
of the slide to the sleeve also engageable with a
support, and contact means controlled by the
slide.
