LIGHTER FOR GAS-STOVES.

Specification of Letters Patent.

Patented June 15, 1915.

Application filed December 21, 1914. Serial No. 878,367.

therein to the accompanying drawing.

My invention relates to improvements in lighters for gas stoves.

The object of my invention is to provide a lighter located between the four burners of a stove and so arranged and constructed that the flame will travel across to the several burners and ignite the same, and also providing a pilot light arranged centrally within the lighter and fed with gas by a separate pipe leading through the supply pipe of the burner whereby the lighter will instantaneously ignite therefrom.

Another object of my invention is to provide a lighter of this character which will produce two flashes to ignite the burners by a single operation of the'valve and thus'insure of the ignition of the burners during one or the other of the flashes.

A further object of my invention is to provide a simple, cheap and effective lighter of this character adapted to be readily applied to the ordinary gas stove and having certain details of structure and operation hereinafter more fully set forth.

In the accompanying drawing, Figure 1 is a perspective view of my improved lighter.

Fig. 2 is a side elevation showing the burner and pilot light in section. Fig. 3 is a top plan view of Fig. 1 showing the controllin valve in section, and also showing the bel surrounding the burner. Fig. 4 is a dlagrammatical view of a stove showing my lighter applied thereto.

Referring now to the drawings, 1 represents the casing of my improved valve wh ch is provided with a tapering central opening 2 therethrough in which is arranged a correspondingly shaped turning plug 3 having a transverse passage 4 therethrough. The casing 1, is provided with an opening communicating with its rear end and having its 7 forward end communicating with the central opening 2. Communicatin with the opening 2 at the forward end of the casing is a passage 6 which has its outer. end in more fully communication with the enlarged internal threaded recess 7. The plug 3 above the casing is provided with a housing 8 having a sprmgtherem adapted to hold the valve in 1ts normal position shown in Fig. 3 of the drawing. The said housing 8 is provided with a handle 9 by means of which the plug is oscillated. The lower endof the plug extends below the housing and is screw-threaded and has screwed thereon a nut 10. Between the nut 10 and the housing 1 and surrounding the extension of the turning plug is a coil spring 11 which normally holds the turning plug in a downward position to form a tight joint with the housing to prevent the leakage of gas therefrom.

Screwed within the internally screwthreaded recess 7 of the housing is a pipe 12 which leads outwardly and has screwed thereon a casting 13 which will be later described. The housing 1 is provided wit a bypass 14 extending around the turning plug 3 and communicating with the pipe 15 arranged within the pipe 12 as clearly shown in Figs. 2 and 3. I

The casting 13 is screw-threaded on the pipe 12 and has a. passage 16 leading diagonally upward to the enlarged recess 17 arranged in the upperend of the casting.

Bemovably secured in the recess 17 1s the burner or lighter proper 18 which is provided at its upper end with the horizontally arranged openings 19 through which the gas passes and flashes outwardly as will be hereinafter more fully described.

The portion 19' of the casting 13 is adapted to support the bell 20 having the usual opening through which the I flame flashes through the openings 19 as fully described in a co-pending application executed on even date," 1915.

The pipe 15 extends inwardly within the casing as indicated at 21 and communicates with a vertically disposed passage 22 communicating with the pipe 23 which extends upwardly through the burner 18 and has its Serial No. 658, filed January 5,

upper end 24 open and which forms the pilot light which is continuously burning. order to control the amount of gas passing to the pilot burner, I provide the casting with a nipple 25 into which is screwed a screw valve 26 having the tapered inner end 27 extending Within the end 21 of the pipe 15 and whereby the gas is controlled to the passage 22 for increasing or decreasmg the pilot light.

In Fig. 4:, the bell 20, as shown, is located 5 centrally between the burners 28, 29, 30'and 31 and there are arranged four openings 19 in the burner 18 to shoot the flame out through the bell in the direction of the arrow shown in Fig. 4 to ignite the severa burners. From the foregoing description it Wlll be seen that when the turning plug is turned with the passage 4 in the direction shown in dotted lines Fig. 3, a certain amount of gas has passed through the passage 4 to the pipe 12 and out through the passage 16, to the Y burner 18' and flashed outwardly through the openings 19 and ignited by the flame at the pilot burner. .This pilot burner, as hereto- 20 fore described, is continuously receiving gas through the bypass 14 and the pipe 15 and is therefore continuously burning. When the turning plug is released, the spring within the drum 8 orces the plug 3.back to the position shown in Fig. 3 shownin full lines,

and a second supply of gas passes through the passage 4 as it registers with the passage 5 and thus supplies a second supply of gas to the pipe 12- to cause a flash from the openj comprising a vertlcally disposed burner havings 19 clearly shown in Fig. 2 of the drawing.

Having thus fully described my invention what I claim and desire to secure by Letters 1 Patent is: p 1.
