1 Claim.

This invention relates to an automatic lighting means for gas or gasoline stoves.

It is aimed to provide a novel construction wherein the gas will be ignited automatically 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 suffice.

The more specific objects and advantages will become apparent from a consideration of the de-- scription following taken in connection with accompanying 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;

Figure 2 is a detail section taken substantially on the line 22 of Figure 1 and on an enlarged scale;

Figure 3 is a detail section taken on the line 33 of Figure 2, and

Figure 4 is a detail section taken on the line 3-4 of Figure 1.

Referring specifically to the drawing wherein like reference characters designate like or similar 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 13, seated in the pipe H and held by fastening means at 14, the valve having an orifice i5 therethrough through which the fuel passes when the valve is open, that is in a position at 90 to that shown in Figure 1.

Rod i2 is rotatable and has a sleeve ll slidable thereon and adapted for manipulation by means of a handle Ill. The sleeve ll has an elongated slot [9 therein through which a screw 20 passes to fasten it against accidental displacement from the rod l2. Sleeve l'l abuts a slide 2| which surrounds the rod 12 forming a journal bearing therefor, and is urged outwardly by an expansive coil spring 22 surrounding rod l2, abutting the fuel pipe I l at one end and the slide 2| at 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 orifices 23 of the burner is adapted to be ignited by an electric spark produced from a plug means at 24. Such plug means may comprise an angular metallic support 25 extending from the burner and carrying a grounded electrode 26 co-acting with an electrode 21 carried by a porcelain or other insulating body 28, the contact or electrode 21 preferably being fastened to the insulation by means of nuts 29 and 30 and being removably and adjustably 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 be removed, adjusted or replaced.

The electric energy for operating the plug may be supplied from any suitable source, for instance 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 spark coil 35 having breaker points 36. Said conductor 3:; has spaced apart contacts 31 therein. A ground wire 38 leads from the other terminal 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.

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 position shown in the drawing, handle 18 is turned 90 so as to place the valve orifice or port it: in

the battery to the coil and spark plug, since the 7 contacts 53 and 37 engage and the contacts 4! and i l engage, and a conductor 45 leads from the latter to the electrode 21. The electrode 26 is preferably removably held in place by a screw 46 threaded to the support 25. As a result of the closing of the circuit, a continuous spark is produced at the spark plug so long as the circuit remains closed. It will be realized, that the circuit will open as soon as the handle i3 is released because 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 invention,

I claim as my invention:-

A device of the class described comprising a valve rod, a slide surrounding and forming a journal bearing for said rod and located intermediate the ends of the latter, said slide being polygonal 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.
