A GAS BURNER WITH ELECTRIC IGNITION
Year: 1885

page_text: We, FELIX GIRAUD and ERNEST NEE, of 19 rue de Paris, Clichy la Garenne,
in the Republic of France, Mechanical Engineers, do hereby declare the nature
of our said invention for A GAS BURNER WITH ELECTRIC IGNITION to be as
follows:
1
Our invention for a gas burner with electric ignition has for its object to
construct a gas burner in which the act of turning on the gas shall also cause an
electric spark to be produced, the said spark serving to ignite the gas.
In a gas burner constructed according to this invention a flexible plate or spring
is fixed upon the body or socket supporting the nipple or burner proper, and is
insulated therefrom. This plate or spring is formed of a conducting material and
is connected to one pole of an electric generator. A rigid conducting rod fixed
upon the cock or plug of the said socket but insulated therefrom is connected to
the other pole of the electric generator. A coil of insulated wire is inserted in the
circuit between the electric generator and the flexible plate or spring, or the rigid
rod-The rigid rod and flexible plate or spring are so situated with respect to one
another, that, on turning the plug or cock to admit the gas to the burner, the rigid
bar makes contact with the flexible plate completing the circuit from the electric
generator, and on the continued movement of the cock or plug in the same
direction this contact is suddenly broken by the resilience of the flexible plate or
spring; the spark formed at the contact on the interruption of the current serving
to ignite the gas escaping from a burner below;. which burner may be either the
main burner or, a supplementary burner employed to light the main burner above
the rod and plate or spring.

We, FELIX GIRAUD and ERNEST NEE, both of 19 Rue de Paris, Clichy la
Garenne, in the Republic of France, Mechanical Engineers, 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 :—
Our invention for a gas burner with electric ignition has for its object to
construct a gas burner in which the act of turning on the gas shall also cause an
electric spark to be produced, the said spark serving to ignite the gas.
In a gas burner constructed according to this invention a flexible plate or spring
is fixed upon the body or socket supporting the nipple or burner proper and is
insulated therefrom. This plate or spring is formed of conducting material and is
connected to one pole of an electric generator. A rigid conducting rod fixed upon
the cock or plug of the said socket but insulated therefrom is connected to the
other pole of the electric generator. A coil of insulated wire is inserted in the
circuit between the electric generator and the flexible plate or spring, or the rigid
rod. The rigid rod and flexible plate or spring are so situated with respect to one
another that on turning the plug or cock to admit the gas to the burner, the rigid
bar makes contact with the flexible plate completing the circuit of the electric
generator and on the continued movement of the cock or plug in the same
direction this contact is suddenly broken by the resilience of the flexible plate or
spring the spark formed at the breaking of the contact serving to ignite the gas
escaping from a burner below; which burner may be either the main burner or
& supplementary burner employed to light the main burner above the rod and
plate or spring.
Figs. 1 & 2 show in front and side elevation a batswing gas burner constructed
according to this invention.
The flexible conducting plate or spring C fixed upon an ebonite insulator E
situated on the body or socket A is connected to one of the poles of an electric,
generator and the rigid conducting rod D fixed upon the cock or plug B of the
socket A is connected to the other pole of the electric generator. When the plug
or cock B is turned to open the passage for the gas, the rod D comes in contact
with the plate or spring C and deflects it. When the cock or plug has opened a
passage for a sufficient quantity of the gas, the rod D and plate C suddenly
separate by the resilience of the plate C and the spark generated at the breaking
of contact by the action of the current on the coil of insulated wire lights the gas
escaping from the burner.
When the device is employed with round burners or those provided with globes
or chimneys, the movement of the rod D above the burner may be obstructed.
In such case we adopt the arrangement shown in front and end elevations in
figs. 3 & 4.
At the moment when the rod D₁ after making contact with the plate C and
deflecting it suddenly leaves it breaking the contact and causing the spark,
a supplementary tube T whose upper orifice is immediately below the spark
allows the passage of the gas which is lighted and which lights in turn through a

page_text: channel or spaces of the holder for the globe or chimney the gas which escapes
from the main burner. The cock or plug B¹ in continuing its movement to fully
open the passage to the main gas burner closes the passage of the tube T.
To extinguish the lighted burner in both cases, the cock or plug is turned in the
reverse direction till the plate and rod after again making contact and separating,
again occupy their original positions before lighting.
Figa, 5 & 6 represent, in central longitudinal section and in cross section, the
coil of insulated wire inserted in the electric circuit.
The soft iron core a having two flanges b b¹ also of soft iron is insulated by
paper pulp or other suitable material and is coiled with copper wire in the
ordinary manner to form a first layer of coils upon which are placed plates of
hoop iron C parallel to the axis of the coil and insulated by air spaces. A band
of linen or other suitable material serves to maintain the plates C in position. The
winding of the coil is continued by forming a second layer of copper wire, a second
layer of plates of hoop iron and so on.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
1. Lighting a gas burner by means of an electric spark generated above the
burner at the moment of rupture of contact between a rigid rod situated on the
plug or cock of the gas burner and connected to one pole of an electric generator
and a flexible plate or spring situated on the socket of the burner and connected
to the other pole of the said generator by a coil of insulated wire inserted in the
electrical circuit substantially as described with reference to figs. 1 & 2 of the
drawings.
2. Lighting a gas burner by means of an electric spark generated above a
supplementary burner but below the main burner at the moment of rupture of
contact between a rigid rod situated on the plug or cock of the gas burner and
connected to one pole of an electric generator and a flexible plate or spring
situated on the socket of the burner and connected to the other pole of the said
generator by a coil of insulated wire inserted in the circuit, the electric spark
lighting the supplementary burner which in turn lights the main burner sub-
stantially as described with reference to figs. 3 & 4 of the drawings.
