This invention has. general reference to devices for lighting burners at a distance from the point at which the flame is applied,

and relates particularly to such a device which is especially adpated for lighting burners which are located in the ovens of gas stoves, in gas p where the burner is not readily accessible for the directapplication of amatch thereto.

As is well known, it is customary to use in the ovens of gas stoves, and in'gas heaters,

one or more burners each in the-form of a straight tube having a plurality,of openings or nipples at one or more sides thereof; and

to light such a burner by applying a match at one end thereof, through an'op'eningprovidedfor that purpose in a wall of the oven or heater, leaving the frame to be communicated by creeping from the first opening or nipple the others. Particularly when the burner is located in a closed space, such as the oven oi? a gas stove, the, length of time required for the flame to creepfrom end to end of the burner frequently is sufficient to allow a considerable quantityof gas to escape into the oven, and it is not uncommon for a harmful explosion to result from this condition, which is a very undesirable one for other manifest reasons, even it an explosion does not occur. i

A primary object of my present invention is to provide a simple and inexpensive device which is readily attachable to the ordinary piping of a gas stove or heater, and by which a flame applied otherwise than dlrectly'to a gas burner havinga plurality ofoutletsfwill be transmitted simultaneously to'niany if not all of such outlets.

Another objectis to'provide such a device which will be thus effective upon a plurality ofburners at the sametime. a v

A further object is to provide a lighting device by meansoi' which flame applied at a distance from a gas burner-will be forcibly transmitted thereto.

And a still further object is to provide such a device in which the transmission of the flame takes place in two or more steps, so that the distance to which such transmission is possible, and its efiectivenessare increased.

The means by which the foregoing and other objects are accomplished by my present invention, and themanner oi their accomplishment, readily will be understood from the following description on referenceheaters,,or in other places to the accompanyingdrawings, which depict preferred embodiments of the invention,'and

in which:- y Fig. l is a plan view, showing two ordinary oven-type I supply piping, and a portion of a wall of the oven, with proved lighting device in both of the burners. V

-Referri'ng now in detail to the drawings, in which like parts are identified by corresponding "reference characters throughout the several views, I have shown, as a means position to serve of illustrating an application of my imply pipe 10, a stop-cock ll being interposed between the burner and said supply pipe. To indicate that the burners are located inside an oven, I have shown a portion of an oven Wall 12 as separating the burners from the gassupply pipe, and I have also shown gas burners, parts of the gas- I preferred form oi my imsaid pipe as being turned upwardly at the pipe, is connected a stop-cock 14:, which I:

have shown as being of a type'that commonly used on stoves, especially in the pipes leading to the burners, and which is well adapted for use with my improved lighting device, since the discharge therefrom is through lateral openings 15 in the nipple 16, which is closed at the end, and the pressure of the issuing gas is distributed, instead of being directed axially of said hi ple. Screwed upon the nipple 16 is a coupend, an'das having vertically above and such as is com-- ling 17, having an enlarged shoulder 18 to facilitate the application of a wrench thereto, and in the outer end of said coupling is screwed a cylindrical tube 19, which is bent downwardly for a reason which will appear hereinafter. Below and in line with the tube 19, a small vent opening 20 is drilled in the end wall of the coupling 17, said opening preferably being inclined toward the free end of the tube 19, on which is screwed a cap 21, having drilled therein two similar small diverging vent openings 22 and 23. The coupling 18 extends through the wall 1.2 of the oven, there being an enlarged opening 25 provided in said wall for the coupling, said opening permittingthe insertion of a match through the wall to ignite gas issuing through the vent opening 20.

In using the lighting device, the cock 14: is opened and the flame of a match is applied to the ventopening 20, the jet from which, being directed toward the cap 21, instantly produces jets at the vent openings 22 and 23, which strike upon and along the respective ones of the burners 5 and 6-, and, upon the opening of either or both of the cocks 11 controlling the admission of gas to the burners, flame will be applied simultaneously to all of the vent openings or nipples that are reached directly by the jets from the vent openings 22 and 23, and the draft created by said jets will cause the entire burner to become lighted almost instantly.

In the arrangement of the gas-supply piping shown in Figs. 1 and 2, which, as stated hereinbefore, is one that is commonly used, the most convenient connection for the lighting device is afforded by the pipe 13,

which is located considerably above the plane of the burners. It therefore becomes desirable to bend the tube19 downward, so that the jets of flame from the vent openings 22 and 23 in the cap 21 may be directed toward the burners and extend a considerable distance along them. It is manifest that a somewhat similar resultmight be ob tained by leaving tube 19 straight, and placing the openings 22 and 23 eccentrically in the cap 21, but in that case said vents would not be as close to the burners as is desirable. Furthermore, it is not unusual for oven-type along the burners as possible.

gas burners to have more than one row of outlets or nipples, and it is then desirable to have the jets of flame from the lighting device strike directly upon all of said rows from a point close thereto, and extend as far The shape of the tube 19, and the location and arrangement of the vent opening20, readily may be changed to suit different conditions.

If only one burner, or more than two, are

to be served by the lighting device, the numher and arrangement of the vent openings in the cap 21 are changed accordingly. Also, it manifestly is feasibleto duplicate the tube 19 and the vent opening 20, while using only one of the couplings 17 Various modifications of minordetails of my improved lighting device doubtless readily will suggest themselves to those skilled in, the art to which it appertains, but such modifications fall within the scope of my inventive rights, and my invention therefore is not to be construed as being limited to any details not specifically set out in the claim. 7

Having now fully disclosed the invention, what I claim as new, and seek to secure by Letters Patent, is I In a gas stove, a plurality of enclosed oven burners of a gas stove oven, said burners being provided with a series of closely spaced openings for the gas to be burned, a gas conduit disposed in proximityto said burners and having openings therein directed along the openings of the burners, a valve controlling the flow of said conduit and disposed outside the oven, a member connected with said conduit from outside the oven and having an opening therein directed toward the openings in the conduit, said oven enclosure being provided with an enlarged opening through which the member extends, whereby when the valve is opened escaping gas from the opening in the member may be ignited from the outside of the oven providing a flame for igniting the gas escapingfrom theconduit openings, and from thence the ignited gas ignites the whole burner.

In testimony whereof I aflix my signature.
