Q I 45 Claims. This invention relates to gas stoves and has more particular reference to a combination therefrom toward the various burners.

lighter and burner support for the cooking top.

Automatic lighters have been applied to gas stoves for several years operating on the flashback principle of Methudy patent No. 1,675,899, according to which principle, when the gas for a burner is turned on, some gas is conducted through a tube to a pilot light where it-is ignited and the flame flashed back through the tube to the burner. It has been common practice to provide the automatic lighter for the cooking top in the form of a spider with the pilot light casing at the center having the flash tubes radiating The spider constituted a separate unit and was arranged to rest on the burners by means of the flash tubes. This arrangement, however, was not very satisfactory because it is practically impossible to have the four cooking top burners supported in exactly the same plane, one or more are bound to be above or below the plane of the others, and in that way the flash tubes for certain burners are not properly positioned with respect thereto for quick lighting. It has also been common practice to have the lighter rigidly supported by itself and to have the cooking top burners resting on another support. That arrangement naturally meant too much chance for improper alignment of each burner with itsflash tube and if anything was more objectionable than the other arrangement just described. It is, therefore, the principal object of my invention to provide for the rigid mounting of the lighter and the supporting of the burners directly on the ends of the flash tubes, whereby not only to eliminate certain parts that went with the, old arrangement, and thus make for simplicity and economy, but, what is more important, also insure proper I relationship of the burners with reference to the flash tubes for quick and positive lighting.

Another object is to provide quick detachability of the burners from this new form of support whereby to facilitate assembling and also make it easier to remove burners for inspection and cleaning.

Another object of the invention is to so construct the combination lighter and burner support that the same is interchangeable for use on stoves having right or left hand ovens. Furthermore, in the case of stoves which are not to be equipped with an automatic lighter, a support generally similar to the combination lighter and burner support can be provided by simply eliminating the lighter casing and merely providing an opening at that point for the projection therethroughof the ordinary flash type lighter, and providing solid arms in place of the hollow flash tubes for support of the burners.

The invention is illustrated in the accompanying drawings, in which- Figure l is a plan view of the cooking top of a gas stove embodying my invention, the grates being removed to'better disclose the invention;

Fig. 2 is a detail of the simmer burner-support taken looking on the line 22 of Figure 1;

Fig. 3 is a cross-section taken on the line 3-3 of Figure 1, showing the combination lighter and burner support in side elevation;

Fig. 4 is an enlarged sectional detail taken on the line 4-4 of Figure 1, showing the quickly a Referring to Figure 1, the numeral 9 is applied to the frame of the cooking top alongside the oven section III which in this case is to the left of the cooking top but may, however, be to the right thereof, as is well known. The usual grates provided for the cooking top and fitting in the recess II in the frame 9, have been removed better to disclose the cooking top burners |2-|5 and the simmer burner IS, which have the usual mixers II where they make detachable connection with the cocks It on the manifold IS. The latter .is shown as exposed but may, of course, be concealed. Heretofore, it was the practice to provide lugs on the burners l2-I5 for supporting the same on a bracket or hanger reaching from one side of the cooking top to the other beneath the burners. An automatic lighter consisting of a pilot light casing at the center thereof with flash tubes radiating therefrom toward the various burners was then simply placed over the pilot light jet and allowed to rest by the ends of its flash tubes on the burners, one certain finger of each burner being provided with an end port for discharging into the flash tubes, and the automatic lighter being supported by its flash tubes on those particular fingers. Now, the fact that the burner support was so crude and there was no provision made to keep the burners from getting cocked out of position one way or another, and the burners were almost invariably never exactly in the same plane, naturally gave rise .to the objection that the lighter would be in proper relation only to certain burners and not to others, and the automatic lighting of the cooking top burners would not be anywhere near uniform; those having the proper relation to the lighter could be lit quickly, whereas the others would light veryslowly, if at all. In the other arrangement above mentioned, where the lighter was rigidly supported by itself, entirely independently of the burners, the automatic lighting of the burners was even less likely to be uniform, for obvious reasons. The present invention avoids the objection noted by providing a novel construction and arrangement of parts which will now be described.

The combination lighter and burner support is indicated generally by the reference numeral 20, and comprises a one-piece casting having the hollow body or casing 2| of the pilot light not only cast integral with flash tubes 2225, but also integral with supportingarms 26 and 21.. The arms 26 and 21 constitute, in effect, a supporting bracket, the former having a cross portion 28 integral therewith fastened as by means of bolts 29 to a hanger 30 having lugs 3| and 32 for engagement above and below the supporting ledge 33 for rigid support at one end of the unitary casting, and the arm 21 having a lug 34 on the end thereof arranged to rest on a ledge 35 to provide support at the other end. Obviously, the bolted connections 29 may be loosened to permit adjustment of the unit 20 relative to the hanger 30 if it does not come in the proper plane when assembled on the stove. The lugs 3 I32 are spaced far enough to either side of the arm 26 to make the unit 20 quite rigid, and the three point support is, therefore, all that is necessary. It is also obvious that the unit 20 can be quickly and easily assembled into the stove and just as easily removed, by virtue of the construction described.

The flash tubes 22 and 25 extend in opposite directions from the casing 2| angularly with reference to the arm 21 for cooperation with the front burners l2 and I5, respectively. The outer ends of these tubes are enlarged, as indicated at 36, for reception therein of the ends of the fingers of the burners in which the ports 31 for delivering gas through the flash tubes are provided, these ports being at a predetermined angle to the plane of the tops of the burners, in accordance with the disclosure of the Methudy patent. The bottom walls of the flash tubes are cut away at the ends 36, as appears at 38, partly to admit secondary air for the jet at the end-most port 31 and partly also to facilitate making detachable connection between the tubes and the fingers of the burners. A lug 39 is provided projecting from the end of each of the flash tubes 22 and 25 at one side of the enlarged portion 36 toserve as supporting ledges for projections provided on the same side of the fingers of the burners l2 and i5. Lugs 4|, suitably cast integral with the fingers of the burners and projecting from the under side thereof, reach under the ends of the flash tubes and engage under small transverse ribs 42 cast integral with the bottom wall of the tubes. From this description it should be evident that the front cooking top burners I2 and I5 are rigidly supported on the ends of the flash tubes 22 and 25, respectively, with the endmost ports 31 on the fingers of the burners adapted to cooperate with the flash tubes disposed precisely in a predetermined desired relation to the ends of said tubes. There is, therefore, no question as to the quick and positive lighting of these burners. The burners can be quickly and easily removed from connection with the flash tubes by tilting the same on the projections 40 as fulcrums and then shifting sidewise enough to bring the projections 40 clear of the lugs 39, whereupon the burners can be dropped down below the plane of the flash tubes and slipped off the cooks for removal from the stove. In the installation of the burners it is only necessary to be sure that the side of the flnger bearing the projection 40 be brought into engagement with the lug 39 with the projection resting on top of the lug; that will bring the ports 31 in proper relation with the flash tube.

In the case of the rear cooking top burners l3 and [4, the connection between the burners and the flash tubes 23 and 24, respectively, is very much the same as that just described, excepting that the two lugs 39 are provided on the end of the flash tubes at opposite sides of the fingers of the burners arranged to cooperate with the flash tubes, and projections 40 are provided on opposite sides of the fingers of the burners to rest on said lugs. Lugs 4| are provided extending from the fingers for engagement under ribs 42 preferably made integral with the flash tubes. In this case, however, the ends of the lugs 4| are provided with shoulders 43 extending upwardly behind the ribs 42 whereby to hold the burners against accidental displacement from connection with the flash tubes. Nothing of this sort is'requiredin the caseof the front cooking top burners, because in that case, as stated above, the side of the finger of the burner comes into engagement with the side of the lug on the flash tube and movement of the burner away from the flash tube is prevented. In removing a burner it is only necessary to tilt it about the projections 40' as a fulcrum or trunnions so as to bring the shoulder 43 clear of the rib 42, whereupon the burner can be withdrawn from connection with the flash tube by movement thereof sidewise away from the tube in a manner believed to be selfevident. In the installation of the burner, the same is slightly tilted as the lug 4| is brought toward the end of the flash tube, and the projections 40 are brought over the tops of the lugs 39' and allowed to rest thereon. The burner is moved toward the flash tube until the projections 40' come into engagement with the end of the tube, so as to insure the positioning of the shoulder 43 behind the rib 42. In case the burner does not happen to be moved in far enough the shoulder 43 coming in contact with the inclined back face 44 of the rib 42' will cause the burner to be drawn toward the tube. It is obvious that each of the burners l3 and I4 is supported rigidly and with its end port 37 in proper relation to the flash tube for quick and positive lighting. It is perfectly clear that the relation of each burner to its flash tube is absolutely independent of the relation of said burner to the other burners.

As a modified or alternative construction, attention is called to Fig. 6 showing a bracket 45 formed integral with the flash tube, indicated at 46, and providing support for the burner 41 adapted to rest on top thereof, as shown, in such a position that the end port 31 of the burner is properly related to the end of the flash tube for quick and positive lighting. As a means of holding the burner in the position shown, pegs 48 may be provided on the bottom of the burner arranged to be received in sockets 49 provided in the bracket, or any other special formation may be provided on the bracket for engagement by the burner with that object in view. It is believed that this construction might be preferred for the reason that it makes it easier to install the burners or remove the same, although it will be evident from the description of Figs. 4 and 5 that the interlocking connection has certain decided advantages.

The simmer burner IS in the case of a stove having a left hand oven is placed to the right of the middle of the cooking top along with the socalled giant burner i 5, but in the case of a stove having a right hand oven, it is placed to the left of the middle of the cooking top, and the burners i5 and I2 are interchanged. The flash tubes 22 and 25 are made of the same length for cooperation with the burners I2 and I5 in either arrangement. The flash tubes 23 and 24 both have webs 50 cast integral therewith to serve as supporting ledges for cooperation therewith of a hook-shaped projection 5| formed integral with the end of the simmer burner it. When the simmer burner is placed on either side of the unit 20 and supported by its projection 5i as just described, it is disposed immediately alongside a hollow neck 52 formed integral with the casing 2| of the lighter and, hence, is arranged to be lit practically the instant the gas is turned on. When the burner isdisposed to the right of the unit 20, a tube 53 is extended from the neck 52 on the left hand side for the lighting of the oven burner, and vice versa.

In operation, assuming that a pilot burner is provided in. connection with the casing 2i, as indicated at 58 in Fig. 3, supplied with gas from the manifold it through a tube 55, when the gas for any one of the burners is turned on, a certain amount of gasiis delivered through the flash tube cooperating with the burner from the endmost port of the burner and is ignited by the pilot light in the casing 2 l. A flash-back occurs through the flash tube and lights the burner. The definite location of each burner to its particular flash tube insures quick and positive lighting so that there is no odor of gas in the room.

In the case of stoves which are not to be equipped with an automatic lighter, a support may be provided for the burners generally similar to the support it but having simply an opening instead of the casing ii, for the projection therethrough of an ordinary flash type lighter, and provided with solid arms in place of the hollow flash tubes for support of the burners. In that way the burners are assured of proper relation to the lighter for quick and positive lighting.

It is believed that the foregoing description conveys aclear understanding of all of the objects and advantages of my invention. Whlle'reference has been made in the description to certain specific details of construction and arrangement, it should be understood that various changes may be made without departing fromrthe spirit and scope of the invention. The app nded claims have been drawn with a view to covering all legitimate modifications and adaptations.
