FLASH-IGNITER AND SIMMERER.

v Specification of Letters Patent.

Patented June 41, 1918.

Application flied August 3, 1917. Serial No. 184,258.

To all whom it may concern.

Be it'known that we, J onus F. Rum and FRANK A. GAUGER, both citizens of the United States, and residen s of Milwaukee, inthe county of Milwaukee and State of Wisconsin, have invented certain new and useful Improyements in Flash-Igniters and Simmerers; and we do hereby declare that the following is a full, clear, and exact description thereof.

The present invention relates to burners adapted to use gaseous fuel, and its objects are, among others, to provide simple and effective means for controlling the flow of the fuel to a burner for lighting the-burners simultaneously or successively from a common pilot light, and for producing and controlling a low simmering flame, and for protecting the parts against impairment b y w the accumulation of carbon; and to provide means for guarding against various undesirable results which sometimes follow from the ;careless use of such burners.

The invention comprises a valve controlling a plurality of Ways and a burner which may act as a lighter for a plurality of other provision of a triple control valve for operating the simmerer, flash igniter and pilot and comprises a simple and compact structure having a single spring means therein for retaining the valve head in the valve casing and the auxiliary valve normally closed.

With the above and other objects in'view, which will appear as the description proceeds, our invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and particularly defined by the appended claims, it being understood that such changes in the precise embodiment thereof may be made as come within the scope of the claims.

In the accompanying drawings we have illustrated one complete example of the physical embodiment of our invention constructed according to the best mode we have so far devised for the practical application of the principles thereof, in which:

Figure 1 is a side view thereof with parts broken away and in section to more clearly define structural details.

Fig. 2 is a sectional view through the burner member on the line 2-2 of Fig. 1.

Fig. 3 is a plan view of the underneath side of the partition between the burner head and simmerer.

Fig. 4 is a sectional view taken longitudinally through the valve.

Fig. 5 is a sectional view, taken on the line 55 of Fig. 4:, and

Fig. 6 is a sectional view taken on the line 66 of Fig. 4. v

Referring now more particularly to the accompanylng drawings, the triple control valve structure includes a main casing 5 having its bore taperingly' reduced toward its lower end in the usual manner of gas stove valves for the reception of a similarly tapered valve head 6 to the upper end of which is secured a handle 7. Extended from one side of the casing is a nipple 8 whereby the casing is secured to the usual main supply pipe (not shown) at the front of the stove and extending from the opposite side of the casing is a boss 10 for the securement of the burner supply pipes.

This valve head controls the flow of gas to the simmering burner, and also controls the-flow of gas to the flash igniter which further serves the purpose of a pilot, and the means for controlling the flow of gas to the simmerer comprises openings in the valve head 6 adapted to register with the supply opening 11 in the nipple 8 and an opening 11 in the boss 10 from which leads a supply pipe 12 to the simmerer to be later described. The upper. end of the valve head 6 is hollow as at 13 and has extending therethrough a central bore 14 in which is slidably mounted the shank 15 of the controlling valve 15 for the flash igniter.

Disposed beneath'the valve head 6 are two compartments 16 and 17 divided by a wallor partition 18 which is centrally and taperingly apertured to provide the seat for valve 15 and the upper compartment 16 communicates by Way of passage 16 with the gas supply pipe 19 for the flash igniter which has its end screwed into the boss 10, said supply pipe 19 surrounding the pipe 12, and the other compartment 17 communicating by means of passage 17 with the gas inlet 11. A small opening 20 being normally opened leads from the passage 17 to the compartment 16 in order to provide a small but steady flow of gas at all times to the flash 7 larged bore 13 of the valve head and surrounding said shank in said bore is an expansile spring 22 urging upwardly against the under side of the button 21. The functions of this spring 22 are various and 'consist in retaining the packing 23 firm against the shank 15 to make a gas tight joint, to normally retain the tapered valve head 15' in its seat and to further retain the main valve head 6in the tapered bore of the main casing.

Taking up now the construction of the flash igniter and simmerer, the same comprising essentially a shell or inverted cup member 25 which is usually punched from 'a Y sheet of light metal and has in its top closed portion a series of apertures 26 and separating this top portion into a chamber or compartment 27 is a partition 28 having its pe ripheral edges bent laterally to form a flange for engaging the inner peripheral wall of the member 25 and has therein near one edge an aperture 29 having lateral flanges therearound for engagement with a connecting nipple 30 whichengages a spray and mixing head 31 having spray opening 32 and air openings 32. H v

This mixing head 31 is carried by a casting 33 and communicates with the supply pipe 12 through which the-supply of gas 1s 0011-.

trolled by means of the valve head 6. The casting 33 is supported by means of the supply pipe 19 which communicates with a flash igniter 34 by means of passage 35 and said flash igniter has in its upper closed end a series of openings 36 each opposite an aperture 37 in. the shell 25 so that when a sudv den supply of gas is sent through pipe 19, a..

stream of flame will-shoot from each opening 36 through apertures 37 to the gas stove burners (not shown) thereadjacent.

In order to prevent soot or carbon from forming in the chamber about the pilot and flash igniter 34 a series of apertures 38 are formed about the shell 25 to insure a circulation therethroug'h of air. The simmerer is ignited by the flames from the flashigniter apertures 37. This is readily possible inasmuch as upon the openingor closing of the valve which feeds gas to the igniter burner 34 the flames will tendfto, creep or lick up the sides of the hood25 and reach the gas which is'issuing from thela-pertures 26.

Thus from the foregoing description taken in connection with the acompanying drawings it will'be obvious that a small pilot light is always burning at the flash igniter 34 and when the button 21 is depressed a sudden flow of gas will pass through pipe 19 and cause a flame jet to project from each opening36 of the flash igniter and play on its adjacent burner, and that when it 1s desired to ignite the simmerer, vthe openings in the valve head 6 are alined with the openings 11 and 11' and at the same time the button 21 is depressed as hereinbefore described.

The present arrangement occupies but little more space than either the simmering burner structure or the flash igniter structure-alone and consequently conduces materially toward a desired compactness of stove structure, in addition to'the provision of a 4 central p'ositionin of both the simmering and flash igniter urners and a triple control valve for the burners.

We claim: 1 I 1. In a structure of the class described, a

control valve including a bored valve casling, said casing having a" single inlet and two outlets, saidin-let and outlets communicating with the bore of said casing, a valve-head in said bore for controlling the passage of fluid from the inlet through one of said outlets, a passage leading from, said inlet, and means carried by said valve head a and independent thereof for connecting said passage and the other of said outlets;

2. In a structure of theiclass described, a triple control valve including a ,valve casing having a single inlet and two outlets,-said casing having a central bore, a valve-head in the bore, a passage in the'valve head adapted to. register withand connect said inlet with one of said outlets, an auxiliary valve mounted in said valve head and adapted to connect the saidinlet with the-other of said outlets, and means for normallyclosing said auxiliary valve.

3. In a structure of the class descrlbed, a

triplecontrol Valve including'a. valve casiliary valve for normally closing said aperburner 34 which project through the large ture and for retaining said valve head in the casing.

engaging a central aperture between said compartments, and spring means for normally seating said auxiliary valve in said aperture and retaining the valve head in the casing.

" 5. A combined simmerer and flash igniter comprisin a hood member adapted to be stamped from a single sheet of material, said hood member having openings in its top wall to provide a simmering burner. and a series of openings in the side wall, a partition near the closed end of said hood member below said first mentioned openings therein, said partition having an opening, a lateral flange formed on the peripheral edge of said partition and engaging the inner wall of the hood member, a flange surrounding said opening in saidpartition, a nipple engaging the last mentioned flange, a spray nozzle projecting into said nipple and hav ing an air passage surrounding the same, a flash igniter' disposed in the hood mem': ber beneath the partition and having a series of -jet openings therein alining with the series of openings in the side wall of the hood'member, a supply pipe for the flash igniter, a supply pipe for said spray nozzle, and a valve for controlling both of said supply pipes.

In testimony that we claim the foregoing We have hereunto set ourhands at Milwaukee, inthe county of Milwaukee and State of Wisconsin.
