SAFETY LIGHTER FOR GAS STOVES.

Application led July 11, 1925. Serial No. 42,871. A

This invention relates to devices for lighting the burners of a gas stove, such as come monly used for cooking and heating purposes.

Stoves of this type ordinarily include a plurality of burners, each having an independent connection with a supply pipe or heater common to all, and being provide Y with 'a control' cock, usually furnished with an extending handle'lever. v

Ignition is generally accomplished by )means of a small but constantly burning gas flame, called a pilot, disposed centrally among the burners, and adapted to direct a jet of llame over the burners, upon the ap-v plication of pressure to a push button valve, causing whichever burner to light that has been opened by its control lever.

Thus two distinct operations are required, '20 first, to open one or more of the lever controlled burner valves, and second, to press the pilot valve, holding it open until the burner or burners have become ignited.

The burner valves are ordinarily loosely fitted and occasionally they become inadvertently opened partially or wholly, by the brushing of garments, mischievousness of children, or other causes, such occurrences being highly dangerous because of the emissions of gas into a room and consequences of inhaling the same, the possibilities of an explosion `and in any event the loss of gas thus esca ing. o Q

It is therefore one of the objects o the .35 present invention to provide a lighting means for the burners that operates automatically upon opening the burner cock, the pilot light being untouched.

It is a further feature to' produce an ignit- .40 ing device that may be applied toy any gas stove of ordinary construction without material change therein, permitting its installation in old stoves as well as new,

These aims and objects, which will become more apparent as the description progresses,

are accomplished by the novel arrangement v of parts' hereinafter described and illustrated in the accompanying drawing, in which Figure 1 is a top plan view of a conventional type of gas stove, the cover grill being omitted over half the area, showing the relative position of the burners and illustrating the application of the improved lighting means.

Figure 2 is an enlarged -sectional view of 'trol the entering air as usual.

d its upper portion, the same having an interior flange 6, arranged ina lower plane, to

receive the removable cover 7, usually presenting a cross barred grating or grilland having circular openings 8 directly above the burners 9. l v

These burners, which may vary in size,

shape, number and disposition, are supplied with gas through tubes 10 leading outwardly through the front of the stove to air mixing bells 11, disposed'in spaced relation in a level plane and provided with means to con- A header 12, connected with any convenient source of gas supply, is held in fixed relation to the front of the stove by supports 13 and provided with a series of cocks 14, controlling the passage of gas to branch nipples 15, one for each of the inlet bells 11, the cocks usually being supplied with lever handles 16, each of which, upon being ygiven a quarter turn, admit gas to the burner with which it is associated.

In the ordinary construction of gas stoves a pilot light is arranged at a point substantially equidistant between` thel several burners, this being suppliedwith a-small quantity of gas and remaining constantly lit, the consummation of gas being negligible, lighting being accomplished by a piston valve, which upon being opened, causes flames to issue from the pilot directed towards each of the several burners.

In the instant arrangement. a small pipe 17,` provided with an adjustable control device 17, communicates with the header 12 and leads to a casing 18, being secured inits bottom wall 19, as shown in Figure 2, this casing being supported in the stove by any suitable means, below the cover 7.

A burner 20, at the end of the pipe 17,

,supplies a fine jet of gas within the casing,

center of each burner and communicating with an open, inverted cup 25 disposed above the center of the burner.

In operation, the pilot burner 2()l being lit, the cock 14 of any desired burner 9 is opened, permitting gas, with a proper proportion of air, to enter the burner, whereupon a portion of the same will rise and be gathered in the cup r to be conducted through the tube 23 to the casing 18 and flame therein.

Immediately the gas entering by the tube 23 is ignited and the llame conducted back through the'same pipe to the .o ened stove burner, causing the same to light almost simultaneously with opening the cock, the

with respect to the burner 9 and in the open-l ing 8 is an invertedanged cup, its flange-31 resting on thecover as shown.

Connecting with the periphery of the cup is a flexible tube 32 engaging in one of the openings 22 of the pilot casing, the arrangement being such that the igniting cup may be readily removed `and vswung out of the way, due to the ilexibility fof the tube 32,

i 35 when desired.

1 From the foregoing it will be seen that a simple device for this urpose has been disclosed in the preferred) ment, but it 1s not desired to restrict the details to the exact -construction shown, it being obvious that changes, not involvin the exercise of invention, may be made wit out conicting with the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is 1.. A gas stove burner lighting device com- Jprising in combination with a suppl pipe leading to the burner, said burner aving form of its embodiimperforate side walls and vertical discharge openings in the upper wall, and a cock ccntrolling the pipe, of a pilot light having av constant lsupply of gas, a casing envelopmg `the pilot, said casing having a top, a shallow inverted cylindrical cup over the burner, at the center thereof and a tube communicating between said cup and the pilot chamber.

2. The combination with a gas stove having one or more burners provided with controllable gas inlets, and a cover having a substantially circular opening over each burner, said burner having vertical discharge openings and imperforate side walls of a pilot casing containing a constantly lit gas jet, an inverted shallow cylindricalcup over each of said burners, and a hollow connection between said pilot casing and inverted Cu n f v Jl`his specification signed and witnessed this 10th day of Jul 1925.
