This invention relates to electrical lighters and the form of tubular members preferably, though
lighting systems for gas burning devices such as
stoves and other devices and particularly for such
devices which embody a plurality of burners po
5 sitioned in compact relationship.
It is an obje'ct of my invention to provide a
simple but highly emcient electrical lighting sys
tem for gasy stoves and the like which may be
manufactured at relatively low cost, which re
10 quires no adjustment and cannot get out of
order and which may be easily installed in con
ventional gas stoves and the like now in use as
well as be embodied in the commercial stoves
during the manufacturethereof.
More particularly it is an object to provide an
electrical lighter for gas stoves wherein incan
descent electrical igniting elements are employed
of the type which become incandescent when the
electrical circuit is closed and wherein such ignit
ing elements are disposed in position 'to be con-v
tacted by_ gas escaping from one or more of the
orifices in the burner thereby eliminating the un
certainty of lighting now prevalent with many
of the lighting systems now utilized and eliminat
25 ing to a large extent danger of explosion and
accumulation of gas.
These and other objects and advantages of the
. invention will be more fully set forth in the fol
lowing description made in connection with the
accompanying drawing, in which like reference
characters refer to similar parts throughout the
several views, and in which:
Fig. 1 is a somewhat diagrammatic plan view
showing an embodiment of my invention applied
to four burners of a gas cooking stove, and
Fig. 2 is a view mostly in vertical section taken
’ approximately along the line 2-2 of Fig. 1.v
In the form of the invention illustrated my
improved lighting system is applied to four gas
40 burners B of a cooking stove, which burners have
the usual circumferentially spaced gas outlets or
orifices O, portions of the burners shown> in Fig. 1
being arranged symmetrically as is the usual case
in gas stove construction. While the invention is
45 illustrated as applied to the top burners of the
stove, it is, of course, equally applicable for light
ing the oven burner.
In the form of the invention illustrated I pro
vide a central supporting member I of any suit
able nature, as shown being in the form of a
shallow -cylindrical casing which may be con
' structed of dielectric material and having a re
movable top plate 4a. A series of shielding mem
bers 5, one for each burner, is supported from the
not necessarily, constructed of heat insulating
and dielectric material, such as porcelain or as
bestos fibre and have their inner ends threaded
or otherwise rigidly secured to the casing 4, and Ul
in communication with the interior thereof. The
outer ends of the several tubes 5 terminate at
points above the corresponding burners B and at
points immediately adjacent one or more of the
orifices O of said burners. The outerv ends of 10
said tubular members may be somewhat flared
and provided, if desired, with recessed lower por
tions 5a to facilitate impingement of gas dis
charged from the adjacent orifices upon the light
ing or ignition elements 6 disposed therein.
The lighting elements 6 are in the form of
conventional electrical heating elements capable,
upon »being electrically energized, of obtaining a
temperature adequate to ignite the gas burned
in the stove’or other device.
The extremity of each of the lighting elements
6 extends at least to the end of its shielding tube
5 and directly above the recessed portion 5a at
the lower part of the tube extremity. Service
wires 'i and 8, as shown, extend through each
of the shielding tubes 5 electrically connecting
the respective lighting elements 6 with a pair of
electrical terminals 9 and i0 which are mounted
in the bottom of the dielectric casing l.
terminals 9 and i0 are connected with a source 30
of electricity and a switch S is interposed in the
electrical circuit, preferably being of the buttonl
type, which is urged, by spring or other means,
to 'normally maintain an open position.
In the form of the invention shown I provide
the end of each of the shielding tubes with a
small deñecting plate II which projects from the
outer end thereof above the heating element and
adjacent orifices of the burner serving to assist
in .deilecting discharged gas against the outer 40
end of the lighting element. 'I’his plate may be
of metal which will adequately resist heat and
flame or may be constructed of suitable non
combustible material.
In operation when it is desired to light one or 45
more of the burners, switch S is closed, preferably
before turning on the gas to the burners and im
mediately thereafter the burner valve is opened,
the several electrical lighting elements being by
that.time in incandescent condition. The dis 50
charged gas from the orifices adjacent the light
ing element lmpinges against the corresponding
lighting element being discharged adjacent the
element and thegas from that orifice and the ad
jacent orifices of the burner is instantly ignited. 55
lmpingement ci the said gas against the lighting
element is assisted by the over-hanging con
struction or" the shielding member, including the
recessed portion da formed in the under side of
the tube extremity as well as the deiiectlng
plate lll.
From the foregoing description it will be seen
that l have provided a simple but highly emcient
lighting system for gas stoves or other devices
embodying one or more gas burners which is posi»
tive in nature, cannot get out of adjustment and
which may be readily installed in conventional
gas stoves now in use.
it will, of course, be understood that various
changes may be made in the form, details, pro
portions and arrangement of the parts without
departing from the scope of my invention, which,
generally stated, consists in a device capable of
carrying out the objects above set forth, and in
the novel parts and combinations oí‘ parts dis
_closed and defined in the appended claims.
What is claimed isz
l. The combination with a plurality of gas
burners having upwardly extending burner ori
25 rices, a lighter comprising a rigid supporting and
housing member mounted intermediately of said
burners, electrical terminals housed therein and
connected with a source of electrical current, a
rigid tubular shielding member for each burner
3@ constructed of non-combustible material and rig
idly secured at its inner end to said supporting
member and wholly supported thereby, each oi
said tubular shielding members terminating
above seid burner at a point somewhat out oí
alignment with one of said burner orifices, an
electric lighting element mounted within the
outer portion of said tubular member and termi- ,
nating adjacent the outer open extremity of said
tubular shielding member, and service wires connected with said electric lighting element and dis
posed within said tubular member and connected
with said electrical terminals within said sup
porting and housing member.
2. Lighting mechanism for e. gas burner of the li)
type havinga series of upwardly extending burn
er oriñces comprising a rigid supporting and
housing member spaced some distance from said
burner, electric terminals housed in said member
and connected with a source of electrical current,
a rigid tubular shielding member constructed of
non-combustible material secured rigidly at its
inner end to said supporting member and wholly
supported thereby and having its outer and free
end disposed above said burner and terminating 20
at a point somewhat out of alignment with one of
said burner orifices, an electric lighting element
mounted within the outer portion of said tubular
shielding member and terminating closely ad
jacent to the outer open extremity of said tubular 25
member, the tubular extremity of said shielding
member being recessed at its lower portion to
facilitate impingement of gas from said criñce
against said electric lighting element, and service
wires connecting said electric lighting element 30
with said electric terminals and being disposed
