LOUIS, MISSOURI, ASSIGNOR TO ME'IEUDY AUTOMATIC LIGHTER 00., OF EAST ST. LOUIS, ILLINOIS, A CORPORATION OF ILLINOIS IGNITION DEVICE FOR GAS BURNE'BS Application filed November 11, 1929. Serial No. 406,119. 7

This invention relates to an ignition device for burners of gas stoves. An object of this invention is to provide an-automatic ignition device for a gas stove burner which is simple, economical and safe. Other and particular objects will appear from the detailed description which follows taken in connection with the accompanying draWings,.in-fwhich Fig. 11 is a plan view of the burner, its

connections, the ignition device, and its connections. Fig. 2 is a cross-sectional view taken on line 22 of Fig. 1. Gas is supplied through a manifold 1 by a valve 2 through an air mixer 3 to the burner '4. The burner *inay be of any ordinary construction having holes 5' in its top wall and may comprise a plurality of arms, as specifically illustrated in the drawin s.

One of the arms is elon ate as shown at 6, to form a connection wlth the interior of a pilot housing 7 in which constantly burns a lighted pilot jet 8 supplied with fuel through the plpe 9 from the manifold 1.

The pilot housing 7 has one or more horizontal outlets 10 to connect with one or more burner extensions 6. .An annular baflie plate 11 is situated above the pilot jet 8 and below the outlets 10. Air is admitted to the pilot jet to form a combustible mixture through a suitable orifice at the bottom' of the housing shown'at 12.

The burner extension 6 is connected to the pilot housing 7 by telescoping its end into a suitable female portion in the housing. The

burner extension 6 is provided with holes 13 in -its to wall of smaller dimension than the regular urner holes 5. Its end wall is closed 0 except for a horizontal opening 14 directed towardthe pilot housing 7 and crossing a vertical orifice 15 between the end-wall of the extension 6 and the pilot housing 7.

' The pilot jet 8 is kept burning continuously. When it is desired to light the burner- Combustion occurs, the flame running back to the hole 14 in the end wall, upward through the vertical orifice 15, igniting the =mixed gases coming through the holes 13 in the extension, and thence over the entire top surface of the burner. As soon as this has occurred, the gas will be consumed to such an extent that no appreciable amount escapes on through the hole 14, and what little does pass through that hole is consumed by a flame which passes upwardly through the vertical orifice 15. The pilot light resumes its normal condition and the pilot housing is otherwise 5 free from flame.

While asshown, the pilot housing is connected to only one burner, it will be obvious that it may be connected to as many as desired, ordinarily four.

From the foregoing, it will be apparent that an ignition device has been provided which is automatic, simple of construction, and safe and efficient in o ration.

Various changes may made in the details of construction within the scope of the appended claims"without departing from the spirit of the inventlon. e I claim: I v

1. In combination with a as burner so adapted to receive a icombustib e mixture, means for. igniting the same comprising a pilot jet, a housing therefor, an extension of the burner' 'having a series of spaced holes through its wall, and a member connecting said extension and housing and having'an orifice positioned and adapted to permit the escape of flame to ignite the combustible IIllX- ture after passing through said holes.

2. In combination -.witlr a gas burner 00 adapted to receive a combustible mixture, means for igniting the same comprising a pilot jet, a housing for said jet, an extension of the burner having a series of spaced holes through its wall, and a connecting element between said housing and said extension communicating withthe burner through a hole in the end wall of the extension and having la1 llateral orifice in communication with said 3. A gas burner having an extension with a series of spaced holes through its wall, a pilot jet, a housing for said jet, an element connecting said extension and said housing and having a lateral orifice positioned and adapted to permit the communication of flame therefrom' to the extension at said holes.

4. In combination with a gas burner adapted to receive a combustible mixture, means for igniting the same comprising a pilot jet, a housing for said jet, an extension on the burner having a series of spaced minor holes through its wall, and a connecting element between said housing and said extension communicating with the burner throu h a constricted opening in the end wall of t e extension and having a lateral orifice in communication with said opening.

5. In combination with a gas burner adapted to receive a combustible mixture, means for igniting the same including a pilot jet, a housing therefor, an extension of the burner having a series of spaced holes through its wall, and a connecting element integral with the extension, the end of said element telescoping into a suitable female portion in the housing.

6. In combination with a gas burner adapted to receive a combustible mixture, means for igniting the same comprising a pilot jet, a housing enclosing said pilot jet, an extension of the burner having a series of spaced holes through its upper wall and havlng an end wall provided with a hole therethrou h, and means including said hole in said end wall forming a communication from said extension to said housing.

7. In combination with a gas burner adapted to receive a combustible mixture, means for igniting said mixture comprising a pilot jet, a housing enclosing said jet and havin an orifice in its lower end for admitting a1r into the housing, an extension of the burner having a series of spaced holes through its upper wall and having an end wall provided with a hole therethrough, and a member connecting said extension and said housing and having an orifice positioned and adapted to permit the escape of flame to ignite the combustible mixture after said mixin said burner.

8. In combination with a gas burner' adapted to receive a combustible mixture.

.an orifice located and adapted to permit the escape of flame to ignite the combustible mixture after said mlxture passes through said first named holes in said extension.
