Specification of Letters Patent.

Patented J une 1?, 1919.

Application filed July 12, 1918. Serial No. 244,548.

To all whom t may concern:

Be it known that I, IRVING J. FoL'rz, a citizen of the United States, residing at the city and county of San Francisco and State of California, have invented new and useful Improvements in Gras-Burners, of which the following is a specification.

This invention relates to a gas burner, and particularly to a burner adapted for generating Vand burning keroseneV gas.

One of the objects of the present invention is to provide a simple multiple burner for domestic use, which can be easily installed in the fire box of a kitchen range or stove, and adjusted when placed in position so as to lit any re box, both for length and width.

Another object of the invention is to provide a plurality of gas generators operable in conjunction with the multiple burner, which is adapted to handle kerosene, and, which may be used as single units if one or more should become inoperable, due to clogging or otherwise, or in unison if a greater quantity of gas is being used.

Another object of the invention is to provide means for obtaining a proper mixture of gas and air, and furthermore to provide means for distributing the gas to one or more of the burners, or to any portion of the same.

Further objects will hereinafter appear.

The invention consists of the parts and the construction and combination of parts as hereinafter more fully described and claimed, having reference to the accompanying drawings in which- Figure 1 is a side elevation of the burner.

Fig. 2 is a plan view of the same.

Fig. 3 is a cross section on line 8 3, Fig. 10.

Fig. 1() is a central longitudinal section of the same showing the piping connections through Which kerosene is delivered to the gas generating tubes of the burner.

- Referring to the drawings in detail, A indicates a casing interior on which is formed a mixing chamber 2, and which also serves as the support for a plurality of burners, generally indicated at 3, 4, 5, 6 and 7. The casing also serves as a base member to the extent that it is adapted to rest upon the grate bars of a fire box, and it also serves as a support for a plurality of generating tubes 8, 9 and 10. The burners shown at 3, 4 and 5 are formed of pipes or tubes which extend through the casing A as shown in Figs. 1, 2 and 3. These tubes are slotted as at 11 to permit the escape of the gas and to form a series of small flames of any shape desired. The several tubes forming the upper burners 3, 4 and 5 are turnably mounted in the casing, and to that extent may be adjusted to direct the flame in any direction desired. The burners shown at 6 and 7 are flat, and are provided with slot-like openings 12 in their outer faces to permit the gas to escape therethrough, and also to produce a series of flames on each side. The burners 6 and 7 arev furthermore divided into upper and lower sections, and both sections may be operated in unison, or either section may be operated independently of the other if desired. This is also true of the tube-like burners shown at 3, 4 and 5, that is, all the burners may be operated in unison, and an one may be operated independently of the other.

It may be further stated that any portion of any tubular burner may be operated if desired. The generating tubes 8, 9 and 10 extend lengthwise of the tubular burners, and are positioned above the same. One end of each generating tube communicates with a manifold as shown at 14 to which kerosene is delivered by means of a pipe 15, the amount of kerosene delivered to each generating tube being` controlled by means of a needle valve 16, one foreach tube. The opposite ends of the generating tubes are connected with pipes 17, and these pipes are extended downwardly in front of the burner, and are then turned inwardly where they terminate in nozzles 18. These nozzles are positioned in direct alinement with a series of mixing tubes 19, there being one for each pipe 17 and nozzle18. `The mixing tubes 19 are carried by the casing A, and they are. slidably mounted therein to permit the said tubes t0 be moved endwise withv relation to the nozzles 18, thereby .providing means for regulating the amount of air admitted with the gas.

Formed on the forward portion of the burner is a casing 20, which communicates with the central burner tube 5. The forward faceof the casing 20 is slotted as shownl ati-21 to permit a portion of the gas delivered tothe tube 5 to discharge therethrough. rllhis gas is ignited, and the flame produced is directed against the pipes 17, which, as previously stated, are connected with the respective generating tubes 8, 9 and 1,0. The flame projected from the casing 2O .against the pipes 17 serves the function of heating the gas during its passage from the generating tubes to the lnozzles 18, or, ,in other words, heat applied at this point prevents cooling of the gas and condensation and precipitation of the same before it discharges through the nozzles into the mixing. tubes. The gas when heated produces considerable pressure, and therefore, discharges from the lends of the nozzles 1S with considerable velocity directly into the mixing tubes 19. A jet action is, in this manner, obtained, and air is consequently drawn into the tubes 19, together with the gas, Ca proper mixture of air and gas being obtained by adjusting the tribes 19 with relation. to the nozzles, that is, endwise movements of each tube pro-vides a means for increasing or decreasing the amount of air admitted.

The air and gas passing through the tubes 19 enters the mixing chamber 2 formed within the casing. `It is here distributed to the several burners; or to one or more of the same as the operator may desire. This is accomplished in the following manner:

Slidably and turnably 4mounted in the lower portion of the casing are three valves such as shown at 25, 2G and 27. Each valve consists of an end disk 28 and a half section of a tube such as shown at 29. Each valve is furthermore providedwith a rod 30, anda. handleextension 31, the rods 30 being projected through the front or door of the furnace not here shown to permit each valve to be readily manipulated by the operator.

By referring to Fig. 1.0 it will be seen that the .mixing chamber and the side burners are divided into two compartments by means of a central partition wall 32, and it can also beV seen by referringA to this figure that one of the valves, ,for instance 26, has been moved inwardly until the disk or head portion 28 of the sameis in alinement with the central partition 32. This indicates that gas admitted through the cooperating mixing tube 19 will pass through the valve and of the side burners can be opera-ted.

into one side of the casing only. This per mits one-half of one of the side burners to be used, and if the valve is pulled clear back to the position shown at 29, both sides of rlope ie valve 26 connects with the side burners shown at 6, while the valve 27 connects with the burners shown at 7. By sliding either of these valves endwise it becomes possible to shut off all the gas to the respective cooperating burners; also to direct the gas to one-half of the same, or to direct the gas to the upper or lower sec-tions of each of the side burners. It furthermore becomes possible to direct all the gas from the valve -26 to the burner shown at 7 or vice versa. This is due yto the fact that caclrvalve may not only be moved longitudinally, but also turned. For instance, by referring togFig.

3, it will be seen that valve 27 is so turned that the gas will `escape in the Adirection of arrow a, thus supplying gas both t0 the upper and lower sections of the burner 7.

lf it is desired to deliver gas to the upper half only, it is accomplished by turning the valve to the position shown at 26, gas will then only be delivered to the upper `half of the rburner as shown by arrow Z). A portion of the gas will also escape into a central chamber ll0, and it .may here be bypassed into the upper-chamber by turning the valve 25 forty-iive degrees beyond the position in which it is shown in Fig. 3.

The several adjustments permit by-passing of the gas through the valves such as shown at 25, 26 and 27, and permit-any one of the generating tubes 8, 9 and 10 to be employed, or all of the same in unison, and all the gas from said generating tubes, or from one or more, maybe directed to any burner desired, for instance, all the gas supplied by the generating tubes may be directed to the upper burners 3, 4 and 5,I or toi-any one of thesame, by directing the gas to the. lower 'chamber a0, and through a valve 25 to the upper chamber. Again any one of the b-urners 3 and 4 may be partly closed, as each of the said burner tubes are provided with independent regulating valves as shown lin Figs. 4 and 5. This valve is exactly similar to the valves 25, 26 and 27, only that it is double in construction, a disk or head member 28a being employed, and two half round sleeve sections 29a. A gas by-passed from the central chamber 2 to the burner tubes 3, 4 and 5 through an opening 50 formed in the lower and central portion of each respective tube. `If the valveshown in Fig. 4, with which said tubesareprovided, is turned with the half round section 29a down, it eanreadily be seen thatthe opening 50 will be closed, andthat no gas `will beadmitted to said tube. Similarly if thevalve is reversed vin position, gas will be admitted. Again if it is desired to admit gas to onehalf of the tubeonly, it is accomplished by sliding the valve endwise, for instance, to the position shown in Fig. 5.

In actual operation with a burner of the character here described, installed in a fire box of a kitchen stove or like device, if it is desired to start the burners, it is accomplished by first filling the priming pan shown at With kerosene from a pipe 61. This pipe connects with an auxiliary tank 62, which is supplied from an exterior tank by means of a pipe 63. This tank is a measuring tank, and will not hold more kerosene than is just suflicient to fill the priming pan 60. The tank 62 is provided with two valves such as at 64 and 65. The valve 65 opens or closes the supply from pipe 63, while the valve 64 opens or closes the connection be tween the measuring tank and the priming pan. Each of the valves 64 and 65 are provided with handles as shown, and each handle is provided with a projecting lug 6 6, which engages a rocking latch 67. When it is desired to fill the priming pan it is rst necessary to close the valve 65. This permits the latch to be moved into the position shown in Fig. 6 and therefore permits opening of thevalve 64, the oil contained in the measuring tank will then escape through the pipe 61 and enter the priming pan. It is then turned to closed position to permit opening of the valve G5. This valve is, however, not opened until the oil delivered to the priming pan has been ignited and all the oil practically consumed. The generating tubes should then be sufli-ciently hot to generate gas and valve 65 may then be opened, the oil is then permitted to discharge through pipe 15, and enters the manifold 14 where it flows to the respective generating tubes and is regulated by the needle valves 16. The oil thus admitted instantly turns into a gas and passes through the respective generating tubes and the pipes 17 to the nozzles 18 from which it discharges directly into the mixing tubes, and finally enters the mixing chamber as described, a distribution of the gas being here determined by the position of the valves, the position of each valve being again indicated by the position 0f the handles 31, as these may serve as indicators for this purpose, for instance, if it is desired to use the baking oven, it is probably only desirable to employ the burners on one side and to direct the heat from said burners toward the oven. Again, if it is desired to cook only, it will probably only be necessary to employ the top burners 3, 4 and 5. Again, if it is desired to heat the water back in the ire box, it may be desirable to employ one of the side burners only.

The provision of two or more generating tubes is also an important feature, as it provides ample means for generating a suilicient quantity of gas to supply all the burners if desired, or one or more if desired. It furthermore permits one or more of the generating tubes to be employed during an emergency, for instance, it might happen that one of the generating tubes might become clogged, this may, therefore, be entirely removed for cleaning without disturbing the operation of the burner as a whole, as the remaining generating tubes will supply the quantity of gas required.l

The device as a whole is simple and substantial, and can, therefore, be readily installed by any one and wherever desired. It is also so constructed that practically any size fire box may be fitted, to the extent that spacer blocks may be inserted between the side burner and the main casing to widen it out if desired. Again, spacing blocks may be placed below the casing to lift it to any ordinary height desired.

I similarly wish it understood that the materials and finish of the several parts employed may be such as the experience and judgment of the manufacturer may dictate; also that ordinary gas may be admitted to the nozzles 1S if it is not desired to generate the gas from kerosene as described.

By referring to Figs. 1 and 2 it will be seen that the upper portion of the casing 8 is slotted as shown at 65a. These slots are provided for the purpose of permitting a certain amount of the gas to escape through the casino and to maintain a flame at these points. lhis flame serves as a pilot light to the extent that it transfers the flame from one end of the burner tube to the other, when one end of the burner only has been employed, for instance, with a valve positioned as shown in Fig. 5 only one end of the burner tube will operate, the flame will then burn from the opening 65a and from the openings formed in that end of the burner. If the valve is moved back to central position then gas will also escape through the opposite end of the burner. This gas will then be ignited by means of the central flame passing out of the opening 65a. The central burner 5 is provided for the purpose of heating the generating tubes and to confine this heat as much as possible by employing a hood Such as shown at 66a. This hood confines the flame of heat about the tubes and thereby reduces the amount of gas required for this purpose, as comparatively little of this heat will escape, and only enough will be required to maintain the generating tubes hot.
