To all whom it may concern:

Be it known that I, EMIL L. CLAUS, a citizen of the United States, and resident of Milwaukee, in the county ofMilwaukee and- State of Wisconsin, have invented certain new and useful Improvementsin Combined Burner Structures for Gas-Stoves; and I .do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to new and useful Such cooking stoves are usually provided with a plurality of main burners and a relatively small simmering burner adapted to supply a small amount of heat for certain cooking operations. In addition to economy of manufacturing costs, a very important consideration in commercial structures of this character resides in the amount of space taken up within the confines of the stove by the burners and their valve connections .with the supply pi e. extending along the front of the stove. en a considerable number of burners are emplo ed in connection with a simmering burner, it is difficult to procure a desired spaced relation of the supplyvalves for the various'burners.

It is therefore primarily the object of my simmering burner with the structure of one of the main burners of'the stove, to pro cure economy in manufacturlng costs and to also dprocure an increased free space within the ticularly, it is an important object to coinbine the control means for both the main' and simmering burners in a single valve structure, to thus reduce the number of valve units along the mam supply pipe of the stove, permitting an increased freedom of manipulation of the valve and lessening the danger incidental to accidental opening of the valves. 7

A further object residesin he provision of an arrangement wherein t e simmering burner and one of the main burners of the stove may be embodied in a single casting to thus avoid the necessity of providing an'ad-' ditional casting for the simmering burner, and to procure an ecgnomy of space which would otherwise be mering burner.

A still further object resides in the pro vision of a valve structure which is 0p'er-' Specification of Letters Patent.

ative to supply gas to either the simmering burnerpr its associated maimburner, and which in certain instances may be manipulated to supply gas simultaneously to both burners. v

In my co-pending, application for patent,

means is disclosed for, automatically actuatmg igniter torches for selective burners. upon opening the supply valves for such burners. In this connection it .is a still further obj ectto automatically actuate an igniter torch for both the simmering and main burners when the combined valve structure is-operated to supply gas to either of said burners.

'With the above and other objects and advantages in view, which will be apparent as the description proceeds, my invention resides in the novel features of construction, combination and arrangement of parts as hereinafter more particularly described and defined by the appended claims.

In the accompanying drawings:

in the pipe-for its inlet portion 7 threaded supplying both the main burner and the si-mmering burner. 1,

As shown in Fig. 1, these burners are preferably embodied in a single casting com- .prising the usual duct 8 for conveying commingled air and gas, this duct being enlarged in substantially cup shape to form the mixing head 9 adjacent the valve, and having its other end merged into and communicating with the hollow annular burner head 10 having radial fins 11 provided with the burner jet openings. In carrying out my invention, the duct 8 is provided preferably adjacent one side with a longitudinal partition 12, which is extended into the burner head and directed laterally to cut oi the adjacent fin, designated specifically at 11', from the major portion of the burner head. This partition is also extended into the mixing head 9 to divide off a corresponding portion ofsaid mixing head. The valve casing is provided with a main discharge nipple 13, projecting centrally into the mixing head 9 in the usual'manner, and has a lateral extension 14 from which a nipple 15 extends for projection into the portion of the mixing head divided off by the partition 12. The usual control valve plate 16 is rotatably mounted on the end of the air mixing head 9, being'apertured at 17 to exposethe mouth of the dividedoff portion of the head in the various adjusting positions of the valve plate.

.Thus, when gas is supplied through the main burner nipple 13, it'will mix with air in the head 9 and pass through the major division of the duct 8 for ignition at all of the jets of the burner head with the exception of the jets of the fin or portion 11. When gas is supplied to the simmering supply nipple 15, it will mix with a sufficient quantity ofa'ir and pass through the minor divisionof the duct 8 for ignition at the jet of the fin 11 to thus supply sufficient heat for the desired purposes of a simmering burner. It is noted that the passageway of the divided off portion of the duct 8'is slightly enlarged within the burner head to facilitate proper admixture of air with the as. g Describing now the valve structure shown specifically in Figs. 2 to 5, it is noted that the valve casing 6 is provided with a torch supply port 18, preferably located under the simmering supply extension 14, and connected b a tube-19 with a torch head 20 pre'ferab y of the type shown in my said copending application for patent, this torch head being adapted to direct a torch toward the burner head to ignite either the main burner or simmering burner section thereof. The usual slightly tapered valve member or key 21 is rotatably mountedin the casing,

being held in seating position by a spring 22 coiled on its lower projected end portion and exerting pressure against'the bottom of the casing 6 and against a washer secured by a screw 23 threaded in the lower portion of a Well 24, extending through-the major portion of the valve member, the lower-portion of thewell being shouldered to seat a disk 25 of lead or other packing material whereby to effectively seal the lower portion of the well. The inlet port 26 of the valve casing is inclined upwardly'in the portion 7, while the main burner supply port27 is inclined downwardly in the discharge nipple 13, said ports thus communicating with the valve member at different elevations, and the valve member is provided at said elevations with passages 28 communicating with the well whereby when the ports and passages are in registry, free flow of gas will be provided through the valve for the main burner, movement of the valve to effect this openposition being procured in the usual manner, wherein the handle 29 of the valve member is swung in a clockwise direction from a closing position substantially parallel to the main supply pipe 5 to a position wherein the handle member extends transversely of the supply pipe, this open position of the valve for the main burner being illustrated in the drawin The valve member is also provided with a torch supply passage 30 communicating with its well at the plane of the torch supply port 18,whereby as set forth in my said co-pending application for patent, a torch flow of. gas will be procured for the torch head upon movement of the valye member slightly past open position for the main burner. The valve casing is also provided with bypass ports 31, controlled by a valve screw 32, for supplying pilot flow of gas to thetorch head.

Gas is supplied to the simmering burner extension 14 through a passage 33 communicating with the well at the plane of said extension, the valve being rotated from closed position in a counter-clockwise direction to procure registry of this passa e 33 with theextension 14. A torch flow 0 gas upon this registry is procured by a passage 34 extendin oppositely from the passage 30 of the va ve member in the plane of the torch supply port 18, the-valve member being rotated slightly past its open position for the simmering burnerto effect this torch flowi An exceedingly. simple and readily operated valve structure has thus been provided whereby upon turning the handle in one'direction from a closed or'neutral position, the main burner will be supplied with gas and ignited, and upon turning the handle in the other direction from closed or neutral position, the simmering burner will be supplied with gas and ignited, a .slight retrograde movement of the valve member in either inl stance serving to shut ofi' the torch flow of as and maintain full supply of gas to either urner. l-It is noted that the various ports of the valve structur e are adapted for registry in four different planes, whereby accidental registry of the ports is avoided, and

by disposing the main burner passa es28 of the valve member in .the two inteme iate registering planes, undesired registry of said members is prevented when the valve memher is swung to torch supply position for the simmering burner.

' In'Figs. 6 to 10, a modified valve structure I is shown wherein the various supply operations are more distinct, to lessen the possibility of accidental opening of undesired ports, and also to provide for slmultaneous supply of gas to both the mainburner and the slmmering burner. In this structure, the inlet port 26* and the main burner port 27 are disposed in a common intermediate plane, the simmering supply port 14 and flash supply port 18 beingdisposed respectivelyabove and below said common plane.

A tapered, valve sleeve is rotatable in the valve casing, and themain valve member or key 21' is rotatable in this sleeve, being provided with a well 24= as heretofore described.

The main valve member is provided in its.

intermediate portion with opposed passages 36 communicating with its well and adapted to aline with the ports 26 and 27, and

- the valve sleeve is provided with passages v 37 also adapted to register with the ports 26* and 27, whereby when all of the ports and I passages are in registry, flow of gas is provided for the main burner.

register with the inlet port 26* and with a passage 39 adaptedto register with the simmering port 14, together with a passage 40 M in the upper portion of the valve member.

The valve memberQl is provided with a handle 29*, and the valve sleeve is provided with a handle 41 movable in a plane unde the first named handle.

Thevdrawings illustrate the open position of the valve for the simmering burner alone, in this position the handles 29 and 41 extending transversely of the supply pipe.

Thevalve sleeve in thisposition shuts off the main burner port 27, the inlet port 26" being open by registry of the sleeve passage 38' and the passages 39 and 40 are in registry with the simmering supply port 14". In the closed position of the valve whereby, as isusual in gas stoves, the handles project substantially parallel to the main supply pipe 5, the opposed passages 37 of the valve sleeve are disposed in registry with the main ports 26 and 27, but the passages 36 of the 'valve'member 21 are disposed out of registry. Thus, to procure flow of gas to the main burner alone, it is merely necessary to grasp the handle 29' and swing the valve The valve sleeve. is also provided with a passage 38 adapted to member in a ClOCkWlSe dlrectlon to a position 1 that upon turning movement of the valve reason of the differential peripheral areas of the valve member and sleeve.

To procure torch fiowof gas in connection with these aforedescribed valve movements, the lower portion of the valve member iS. provided with a passage '42 adapted to registransverse of the supply pipe,- it being noted member, the sleeve will remain stationary by ter with the torch supply port 18 when the valve member is swung slightly past its full registering position with the main valve. The valve sleeve is also provided with passages 43 which register with the torch supply port l8 vwhen the sleeve is'in full closing position of the valve or in a position of the'valve which supplies the'si mmering burner alone.

Although the present valve is capable of other use as will be later described, it' is desired to point out that by the afore described structure, I have provided an arrangement wherein opening movement for supplying eitherthe main burner or the simmering burner may be procured by rotating either one or both of the handles through a substantially quarter rotation and in the conventional clockwise direction, it being noted that the controlling movement for supplying the main burner is carried out in entirely conventional manner.

the simmering burner, and to this end, the valve sleeve, is provided with a port 44 which is adapted to register with the sim- The present valve structure embodies also an arrangement for supplying gas simul-. 'taneously to both the main burner and mering. supply ports 14 when the valve sleeve is rotated through 'a half-circle from its full closing position, and the sleeve isialso' provided with a passage 45 adapted to register with the torchsupply port in this position of the sleeve. Hence, when the sleeve is swung to this extreme position, it affords free passage through all of the ports of the valve and when the valve member is swung to open position, gas is supplied through the main and simmering ports 4 and may also be supplied through the torchsupply port. The valve'sleeve is limited to.

' of the main burner head, said supply duct being provided with a longitudinal partition 12 defining a passageway commumeating with the pipe 50 and with the'sim- .mering supply nipple 15 ofthe valve.

While I have shown and described 'preferred embodiments of various phases of my invention, to meet differing'desired conditions of use, it will be appreciated that still other embodiments involving various changes and modifications of structure may be employed to meet other conditions of use and manufacture. without departing in any manner from the spirit of my invention as defined by the accompanying claims.
