GAS STOVE 2 Sheets-Sheet 2 Filed Jan. 2, 1930 A T? RNEYS Patented May 25, 1937 UNED ST'El'fi ATENT QFFEQEE GAS STOVE Application January 2, 1930, Serial No. 417,916
The main objects of this invention are:
First, to provide in a gas stove an improved ignition means whereby not only the open cooking top burners are effectively lighted by means of a flash pilot but also the oven burner.
Second, to provide an ignition means for gas stoves by means of which closed burners, such as an oven burner, disposed at a considerable distance from a flash pilot operatively associated with the open top cooking burners may be effectively lighted.
Third, to provide an ignition means for a closed burner which enables the visual determination of the condition of the burner from the outside of the closed chamber.
Objects pertaining to details and economies of my invention will definitely appear from the description to follow. The invention is defined in the claims.
A structure which embodies the features of my invention is clearly illustrated in the accompanying drawings, in which:
Fig. 1 is a fragmentary plan view of a gas stove or range embodying the features of my invention.
Fig. 2 is a fragmentary vertical section on line 2-2 of Fig. 1.
Fig. 3 is an enlarged detail section in accordance with Fig. 2 showing further details of the ignition means.
Fig. 4 is an enlarged detail partially in section on a line 44 of Fig. 1 showing details of the simmering burner and its ignition means.
Fig. 5 is a fragmentary plan View of the oven or closed cooking unit pilot burner.
Fig. 6 is a fragmentary view partially in section on line 6-6 of Figs. 1 and 5.
In the embodiment of my invention illustrated I provide an open or cooking top designated generally by the numeral i and a closed or oven unit designated generally by the numeral 2. The open cooking top unit comprises a burner chamber 3 having a plurality of main burners arranged thereon as 4, 4 and 5, 5, the burners 4, 4 being the front burners and the burners 5, 5 the rear burners. The open cooking top I is provided with a grid 6. The oven or closed unit is provided with a burner l.
The simmering burner 8 arranged in the burner chamber 3 is disposed at one side of the burner chamber and between one pair of front and rear main burners. The several burners are provided with independent valves designated generally by the numeral 9. A jet 39 is arranged opposite the flash tube 32.
The Bunsen or mixing tubes in of the rear burners 5 are disposed side by side between the front burners 4.
I provide a flash pilot I I for the burners 4 and 5 which is controlled by a valve l2, its tube i3 being supported by a plate-like bracket M disposed between the burner tubes IQ and recessed at !5 to engage the sides thereof. The flash pilot is thus supported in proper relation so that its flashing jets indicated at It are projected toward the burners 4 and 5. The bracket 14 is provided with a pair of upwardly projecting lugs H between which the tube i3 is seated. A pin I8 is arranged through these lugs above the tube for locking the tube in position.
I provide an oven pilot burner which projects through the wall 20 between the burner chamber 3 and the oven chamber and into operative relation to the burner I. This pilot burner 19 has a longitudinal slot-like jet opening 2! in its top, a jet opening 22 directed toward the burner and a rearwardly opening jet opening 23 within the burner chamber 3. A portion of the slotlike jet opening 2| is also within the burner chamber 3 so that when the pilot burner 59 is burning a portion of its flame is visible from the outside of the oven chamber or from above the chamber 3.
Gas is conducted from the oven burner valve to the burner 1 by a conduit 24, the pilot burner 0 l9 being connected to the conduit 24 by a conduit 25 so that the single valve controls both the pilot burner and the oven burner.
The pilot burner I9 is provided with a flash back ignition tube 26 to which the jet 23 delivers. This burner is also provided with a socket 2'! supporting the outer end of tins flash back tube 25, its inner end being supported by a seat 28 provided therefor on the adjacent inlet tube H) of one of the burners 5.
The simmering burner is provided with a laterally projecting lug 29 having a hole 30 therein engaged by a pin 3| on the flash back ignition tube 32. The inner end of this tube is supported by a seat 28 on the adjacent burner inlet tube [0. The inner ends of these flash back tubes are thus supported in proper relation to the flash pilot ll so that the flashing jets directed toward the rear burners 5 are projected across the inner ends of these flash-back ignition tubes, and both I the oven burner and the simmering burner are ignited by flashing the pilot. The operation, for instance, in lighting the oven burner is to open the oven burner valve and then flash the pilot, or flash the pilot and open the valve, as may be desired; although, of course, the flash of the pilot should be maintained until the pilot burner I9 is ignited through the flash back in its ignition tube, the pilot burner IS in turn igniting the oven burner. As both the oven burner and its pilot burner are controlled by the same valve, the operator is not confused in this manipulation.
The simmering burner is lighted in the same way, that is, through flashing the pilot. The operator may thus visibly determine the operation of the pilots, both the flashing pilot and the closed unit pilot.
The burners 4 and the simmering burner 8 are supported by a rod 33 disposed transversely across the oven chamber 3 and is removably supported at its ends by the seats 34, see Fig. 2, so that the burners and parts arranged Within the burner chamber may be readily removed.
The inlet or Bunsen tube 35 of the simmering burner rests upon this rod and is positioned thereon by means of the collars 36 and 37. The collar 31 is adjustably secured to the rod by means of the set screw 38. The parts are thus effectively supported in their proper relation to each other.
I have illustrated and described my improvements in a very desirable and practical embodiment. I have not attempted various other modifications and adaptations which I contemplate as it is believed this disclosure will enable those skilled in the art to embody or adapt the same as may be desired.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
1. The combination in a gas stove, of front and rear open top cooking burners, a simmering burner disposed between the front and rear burners, the rear burners having inlet tubes disposed in side by side relation between the front burners, a flash pilot disposed centrally relative to said burners and between the said rear burner inlet tubes, a supporting bracket for said flash pilot engaged with the said tubes, said simmering burner having an inwardly projecting lug thereon, the adjacent burner inlet tube having a back flash ignition tube seat thereon, and a back flash ignition tube resting on said lug on said simmering burner, the inner end of said ignition tube being disposed in said seat on said burner tube whereby it is supported in operative relation to a flashing jet of said flash pilot.
2. The combination in a gas stove, of front and rear pairs of open top cooking burners, the rear burner having inlet tubes disposed in side by side relation between the front burners, a flash pilot disposed centrally relative to said burners and between the said rear burner inlet tubes, and a supporting bracket for said flash pilot engaged with the said inlet tubes.
