FLm'r LIGHTER Fon Gas s'rov'ns Joseph Cowell, Brooklyn. N. Y. Application December 12. 1945, Serial No. 634,534 (ci. 12e-a9) i 4 claims. 1

This invention relates to an igniter and morev particularly to an igniter for use on domestic gas ranges. vThe primary object of the invention is to ignite the burner or burners ot a gas range when the ow of gas to said burner or burners is established.

Another object is to avoid the expense ordinarily involved through the use of pilot lights or the like.

A further object is to facilitate the conversion of an ordinary gas range having no igniter into an igniter equipped range with a minimum of labor and expense.

The above and other objects may be attained by among its features a standard adapted to be attached to a gas range beneath a hood to which a combustible mixture is conducted from each burner, a pair of opposed ilint holders carried by the standard beneath the hood, a guide sleeve on the standard. a push rod slidable in the guide sleeve, a rasp on the push rod and operable between the ilint holders and flints in the fiint holders yieldingly engaging the rasp whereby when the push rod is advanced the rasp will strike a spark through contact with the iiints and ignite the gas beneath the hood.

In the drawings:

Figure l is a horizontal sectional view through a ydomestic gas range equipped with an igniter embodying the feature to this invention,

Figure 2 is a transverse sectional view through Figure 1, Figure 3 is a fragmentary perspective view showing the flint holders and rasp in detail, and Figure 4 is a longitudinal sectional view through one of the ilint holders.

Referring to the` drawings in detail, a range designated generally by the numeral II) is provided with the usual front apron II which is pierced at spaced intervals to receive the burner control handles I2 by means of which a combustible mixture of gas and air is introduced through feed pipes I3 to conventional gas burners I4. The structure so far cited is of conventional form and forms no part of this invention.

Formed in the front wall or apron II substantially midway between its ends is an opening I5 the purpose of which will be more fully hereinafter explained.

Supported on tubular conduits I6 which rest on the burners I4 is a hood I1 having an opening I l in its side wall the purpose of which will be more fully hereinafter explained. The conduits I l are arranged to receive'a portion of the comemploying this invention which embodies bustible mixture from any one of the burners which may be turned on and to conduct it to the interior of the hood in a manner well known and l is carried by the push rod I9 near the end which projects through the opening I5 in the apron II and surrounding the projecting end of the rod is a compression coil spring 24 the outer end oi which bears against a. knob 25 carried by the extreme outer end of the rod while the inner end of the coil'spring 24 bears against the outer face of the apron II so as normally to hold the rod retracted as illustrated in Figures 1 and 2. A rasp 26 is carried by the end of the nod I9 opposite the knob 25 and is disposed between flint holders to be more fully hereinafter described.

Secured to the upper end of the standard 22 is a yoke 28 the upper end of the legs of which are bent inwardly in opposed relation as at 21 and attached as by screws 28 to these inwardly bent portions 21 are iint holders 29 which take `the form of open-ended sockets in which ilints 30 are received. The ends of the sockets 29 opposite their open ends are provided with internally screw threaded sleeves 3I for the reception of the shanks of adjusting screws 32 the heads 33 of which are disposed outwardly to facilitate turning of the screws. The inner ends of the screws bear against pressure plates 34 which in turn bear on compression coil springs 35 which are disposed behind the fiints 30 so yieldingly to urge the ilints out of the open ends'of the sockets 29. Since the rasp 26 is disposed between the adjacent open ends of the sockets 29 it will be obvious that the iiints 30 will be yieldingly urged against the rasp 26 so that when the latter is moved a spark will be struck. i

In operation it will be understood that when one of the burner control members I2 is turned to open the gas valve a combustible mixture will flow through the pipe I3 to its respective burner I4 and will be conducted from the burner through one of the tubular members I6 into the hood I1. Upon applying pressure to the knob 25 the push rod I! will move the rasp 28 and through the 'yielding engagement of the flints 30 with the pressure on the knob 25 the spring 24 will restore the parte to initial position ready for a repeat operation.

From the foregoing it will be obvious that a simple and emcient igniter is provided which may readily be attached to conventional gas ran-ges so as to add materially to their convenience of operation.

While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.

What I claim.:

1. The combination with a gas stove having a front apron, a plurality oi burners, a hood and tubular gas conduits establishing communica tion between the burners and the hood, a standard supported on the stove beneath the hood, a pair of oppositely disposed int holders on the standard and located within the hood, a rasp slidable between the int holders, ints in the holders, means within the holders to urge the hints into yielding contact with opposite sides of the rasp and means operable through the iront apron for sliding said rasp and striking a spark.

2. The combination with a sas stove having a front apron, a plurality of burners, a hood and tubular gas conduits establishing communication between the burners and the hood.. a standard supported on the stove beneath the hood, a pair of oppositely disposed dint holders on the standard and located within the hood, a guide sleeve on the standard, a rod slidable through, the guide sleeve and the apron, a resp on the rod slidable between the flint holders, iints in the iint hold- `ers and means within the holders to urge the lints into yielding contact with the rasp whereby when the rod is moved a spark will be struck beneath the hoodu 3. .An igniter for a gas range having an lgniter hood and a gas conduit leading from each burner to the hood comprising a standard adapted to be attached to the range beneath the hood, a pair of opposed flint holders carried by the standard. a guide sleeve on the standard, a push rod slidable in the guide sleeve, a rasp on the push rod and operable between the flint holders, ints in the flint holders and means in the holders to urge the ilints into yielding engagement with the rasp whereby when the push rod is advanced toward the standard the rasp will strike a spark through contact with the aims.

4. An igniter for a gas range having an igniter hood and a gas conduit leading from each burner to the hood comprising a standard adapted to be attached to the range beneath the hood, a pair of opposed dint holders carried by the standard. a guide sleeve on the standard, a push rod slidable in the guide sleeve, a rasp on the push rod and operable between the flint holders, ints in the iiint holders and means in the flint holders to urge the ints into yielding engagement with the rasp whereby when the push rod is advanced towardthe standard the rasp will strike a spark through contact with the ints and yielding means to retract the push rod and rasp.
