Sept. 6, 1932. P. V.-GIOE SAFETY ATTACHMENTFQR FLUID BURNERS Filed April 21, 1930 ATTORNEYS Patented Sept. 6, 1932 PETER 'v. c1013, 01 BROOKLYN, NEW YORK SAFETY ATTACHMENT FOR FLUID IBIl'RNERS Application filed April 21,

This invention relates to a safety attach ment for fluid burners, and comprehends a re-igniting means which is especally designed for use in connection with the burners '0 gas cooking stoves and which isadapted to function for the purpose of re-igniting the burners in event the same are extinguished by adraft or as the result of the boiling over of a liquid from a vessel being heated over the burner.

The invention particularly comprehends in connection with valve controlled fluidburners having a burner head formed with a multiplicity of outlets, a safety or re=igniting attachment which includes a conduit, one end thereof constituting an inlet which covers and communicates with at least one of the burner outlets and serves as a means for conducting a'portion of the fluid supply'tothe burner head, from said burner head toa protected outlet end of the conduit to provide a pilot burner independent of the burner head, which pilot burner is' disposed in such a osi tion as to be lighted coincident with the light ing of the burner head, and which pilot burner is shielded from drafts or liquids which may operate to extinguishthe flame of the burner head proper, whereby said shielded pilot flame will function in the capacity of a means for re-igniting the burner in event of its extinguishment from-the above mentioned causes.

The invention as a further object aims to provide a re-igniting device or attachment for fluid burners, especiallygas cooking stove burners of the type which are now in general use, which device is so constructed as to lend itself to ready attachment to the burner head or detachment therefrom without necessitating alteration to' the burner head or requiring the use of special tools or the services of a skilled mechanic. V

Otherobjects of the invention reside in the comparative simplicity of-con'struction of the device or attachment, the economy with which it may be manufacturedandproduced' and the general efflcien'cy derived therefrom.

With the above recited and other objectsin view, reference is 7 had to the following de scription and accompanying drawing, "in

1930. Serial No.- 446,053.

which there is exhibited due example or'em-- of Fi ure 2.

Re errin to the drawingby characters of reference, designates a gas burner head of the conventional type which is used on gas cooking stoves and which presents a plurality of radially'projecting hollow fingers B, which fingers are formed with burner outlets or apertures C in their upper walls, and which burner head is carried by and communicates with a feed pipe D for admitting the gas or fluid'tog'ether with air tothe burner head A. I r

The safety attachment or re-ig'n'iting' device designated generally by the reference characterbroadly consists ofa conduit or pipe 5,

'the intake end 6 of which is provided with m'eans'which covers and communicates with at least one of the burner outlets and conducts the fluid therefrom to the opposite outlet 7 to provide a pilot flame Fat this point which will be lighted coincident with the burner,and which outlet end 7 is formed with meansfor shielding the pilot light or flame F I y from drafts or liquids which may tend to extin guish the flame at the other burner outlets.

As illustrated, the means which carries and communicates with the inlet end 6 of the conduit 5 and which covers the burner-outlets C V is in the nature of a cap or inverted cup sha'ped'element 8 defining a chamber!) which opens on the under side of the cap 8to'establish communication withone or more of the burner apertures'C when the bottom of the cap is disposed in fiat contact with the upper is urfia'ce of one of the fingers B of'the burner lea In order to clamp and retain the cap 8 in i juxtaposition to the burner finger B, the cap is formed as part of a C-clamp 10, the subterposed terminal 11 of which underlies the burner finger and receives therethrough a clamp screw 12 which is adapted to be forcibly advanced against the under side of the burner finger for drawing and impinging the under side of the cap 8 against the upper face of the burner finger.

The means at the outlet end 7 of theconduit 5 for shielding the pilotjlight or flame F consists of a substantially semicircular or concavoconvex hood 13 which is attached or anchored in any suitable manner to the outlet end 7 without obstructing the free exit of the gas or fluid therefrom and which serves to prevent fluidsdescending from above from aflz'ecting the pilot flame F while at the same time shielding said flame F from side or down drafts.

' As illustrated, the inlet end 6 of the conduit extends throughone margin wall of the cap 8 and communicates with the chamber 9. The conduit 5 extends outwardly in a substantially horizontal plane from the cap and is bent upwardly and inwardly at the remainmg end which defines the outlet extremity 7.

In applying the device or attachment, it is obvious that it is only necessary'toassociate the cap 8 with any one of the burner fingers B in such a manner thatthe chamber 9 is in free communication with one or more of the burner apertures or outlet openings C, being sure, of course, that the reversely bent outlet end 7 is directed inwardly towards the center of the burner head A.

In use and operation, with the device or attachment applied as illustrated, when the burner is turned on and ignited,.the outlet end 7 will be disposed in close enough proximity to the lighted burner to insure the igniting of the pilot flame F coincident with the ignition of the burner. It thus follows that in the event of the burner being extinguished by liquids descending thereon as the result of the boiling over of the same from a vessel being heated over the burner or by downfor side drafts, the shielded pilot light or flame F will serve as a means for reigniting the burner.

' When the flame is extinguished by liquids descending thereon, the burner head outlets are obstructed temporarily by the liquid and, hence, the full force of the fluid pressure to the burn er head will be directed to the pilot burneroutlet increasing the pressure at this point and, hence, increasing the length of the pilot flame for more effectually re-igniting the'burner, head.

' Fromjthe foregoing, it will thus be seen that a safety attachment has been devised, which will effectually act as ameans for avoiding the accidental escape of gas or other burner fluids and the possible serious consequences which may result therefrom While the invention has been illustrated in its preferred form, it is to be understood that no limitation is intended as to the precise structural details herein disclosed, as it is to be clearly understood that variations and modifications thereof which fall within the scope of the appended claims may be resorted to when found expedient.

What is claimed is:

1. 'A re-igniting device adapted for attachment to'a fluid burner head having a plurality of burner apertures comprising an inverted cup shaped element defining a chamber open on the under side and adapted to be secured in contact with the burner head over one of the burner apertures to vestablish communicationbetween said burner aperture and the chamber, a conduit extending from said member and communicating with said chamber and a shield carried by the opposite outer end of the conduit for protecting the same against extinguishment by drafts or liquid which may descend upon the burner head.

2. A re-igniting attachment for fluid burners of the type which are provided with a plurality of burner apertures, said attachment including a conduit, an inverted cup shaped member carried by and communicating with one end of said conduit for engaging over at least one of said burner apertures to receive and convey thefluid to the conduit and means at the opposite end of said conduit for shielding a pilot flame ignited coincident with the lighting of the burner, to protect said pilot flame against-extinguishment by drafts or liquids whichmay descend upon the burner head, whereby said pilot flame serves as a means for re-igniting the burner in event of extinguishment of said burner flame by said causes.

3. A re-iginiting attachment for a fluid burner of thetype which is provided with a plurality of burner apertures, including means communicating with the burner head for receiving a portion of the fluid supplied thereto and for providing a fluid outlet independent of the burner head adapted to be lighted coincident with the lighting ofthe burner head and protected against extinguishment by drafts or by liquid descending thereon, whereby to serve as a pilot flame for re-igniting the-burner flame in event of extinguishment of said burner flame from said causes, saidmeans comprising a cap de- 7 meanscommunicating with the burner head for receiving a portion of the fluid supplied thereto and for providing a. fluid outlet independent of the burner head adapted to be lighted coincident with the lighting of the 5 burner head and protected against extinguishment by drafts or by liquid descending thereon, whereby to serve as a pilot flame for reigniting the burner flame in event of eX- tinguishment of said burner flame from said 10 causes, said means comprising a cap defining a chamber adapted to be secured in juxtaposition to the burner with the cap chamber in communication with at least one of the burner openings, a conduit extending from 15 the cap and communicating with the cap chamber, a shield carried by the opposite end of the conduit and means carried by said cap for removably clamping the same in juxtaposition to the burner. 29 Signed at Brooklyn in the county of Kings and State of New York this 17 day of April A.
