- SAFETY DEVICE Application filed June 26,

The present invention relates to improvements in safety devices for gas stoves, primarily adapted to prevent the escape of the gas into a room or dwelling in the event the I gas is accidentally, or otherwise, turned on.

The invention contemplates the provision of a pilot-light in direct communication with a burner, or plurality of burners, whereby a flow of gas through an unlighted burner will be reduced to a flame to the end that the escape of gas into a room may be positively precluded.

The invention further includes the provision of a novel form of burner directly connected to a pilot light and associated with a deflector member for directing any escaping gas in close proximity to the flame of the pilot light in order that combustion may take lace.

p A further object is to provide novel means for controlling the flow of gas to the pilot light, whereb accidental turning on, or shutting off 0 the gas, is prevented.

Still another object ofthe invention is to rovide novel means in the form of a deector member, said member being arranged in substantially spaced concentric relation with the extension connecting a burner and the pilot light casing to permit the directive an flow of the gas to the flame of the pilot light.

As will presently appear the invention is especially adapted to prevent death by asphyxiation in the event a lighted burner is extinguished by the wind, or the like, or a 5 control valve is thoughtlessly or accidentally left opene'd or becomes opened.

With these objects in view, together with others which will appear as the description proceeds, the invention resides in the novel formation, combination, and arrangement of parts, all as will be described more fully hereinafter, illustrated in the drawings, and particularly pointed out in the claims.

In said rawin sz Figure 1 is a p an viewof a gas stove embodying my invention.

Fig. 2 is a fragmentary sectional view taken substantially" on the line 22 of Fig. 1, the deflector members being omitted.

Fig. 3 is a sectional view taken on the line OF NEW YORK, N. Y.

FOR GAS STOVES 1928. Serial in. 288,455.

33 of Fig. 1 to depict the association of the pilot light casing and the deflector members.

Fig. 4 is a transverse sectional view of a deflector member as viewed on the line H of Fig. 3, certain other parts being excluded for clarity.

Referring now in detail to the accompanying .drawings, wherein like characters of reference denote similar. parts throughout the several views, let 5 represent the top ofa 9 gas stove of conventional design, which' is provided with a plurality of burners 6, 7 8 and 9 and a main gas supply pipe 10 extend-v ing from the usual mains. Each of said burners isprovided with a conduit leading from saidsupply pipe 10; burner 6 for instance having a conduitjll through which the gas, under control, by means of valve 12, passes to said burner for subsequent ignition. Burner 7 is likewise provided with a conduit 13 extending from the supply pipe 10, the gas flowage being controlled by valve 14. Conduits 15 and 16 are provided for burners 8 and 9 respectviely, the gas being passed to the same by operating valves 17 and 18. The usual air intakes, as indicated at 19, are provided for each of said conduits.

While each of said burners is somewhat conventional in design, it Will be observed. that each is provided with an extension 20 leading to the pilot light casing 21, the latter being spherical in form and internally, connected to said supply pipe 10 by means of tube 22, the flow of gas from the latter being .controlled by a globe va -"e 23,-as clearly shown in Fig. 1. In the present example of the invention said pilot light casing 21 is positioned centrally of the burners and hence the extensions 20 are directed radially from said burners, it being of course understood that other arrangements are contemplated according to the particular type of gas stove employed.

Upon inspection of Figs. 1 and 3 it will be observed that the ends of said extensions 20, adjacent the pilot light casing 21, are each apertured, as indicated at 24, and that each of said extensions support a deflector member 25, the forward end of said member, adjacent the casing 21' being curved upwardly to de- .previously described, it is manifest that the valve 23 must be manually operated to direct the gas to the pilot light or to stop the flow of gas thereto. Hence accidental opening or closing of this valve is exceedingly remote, but a different situation'presents itself with respect to the valves in the supply pipe 10,

,usual openings in the burners.

which require but a slight movement toefi'ect their opening and closing.

However, with the pilot light ignited, it is obvious that the opening of any of the valves in said supply pipe 10, will cause the flow of gas to a selected burner or burners and thence through a particular extension 20 into the pilot light, to be ignited at the tip 27. In view. of the lips 28 and 29 associated with each of the deflector members 25, (see Fig. 3), the latter are each spaced from the end of said extensions 20 to provide a space clearly shown in said figure. Ordinarily the pilot light is shielded from currents of air and always left burning so that by turning on the gas through either of the valves in the supply pipe 10, the gas flows to the burners, as aforesaid, and finally escapes through apertures 24'over the burner tip 27, as indicated by the'arrows, where the pilot flame ignites the same and also the gas escaping from the The stove is now ready for use.

From the foregoing it is obvious that the accidental opening ofany of the valves in the supply pipe 10, causes the gas to flow as aforesaid, to and into the pilot light where it is ignited and thisof course re-lights the burner in case of said accidental opening. Therefore, no raw gas can possibly find its way into a room or home without coming into contact with the pilot light and becomin of itself ignited.

hile the present is a disclosure of the preferred embodiment of the invention, it is to be understood that the invention is not limited thereto, as various changes in the minor details of construction, proportion and arrangement of parts may be resorted to without departing from the spirit of the invention as defined in the appended claims.

I claim:

1. In a gas stove, a pilot light casing having a tip, a burner including an integral extension connected to said pilotlight casing and having an aperture adjacent said casing whereby gas is conducted from said burnerto a point adjacent said casing and a deflector spaced from said aperture and having its outer edge spaced from the tip of said pilot light casing and adapted to direct the flow 0 gas to said tip.

In testimony whereof I aflix m signature.
