16 Claims.

This invention relates to a valve and burner construction.

Objects of this invention are to provide a multiple burner construction in which there is 5 a center burner, a succeeding burner, and an outer burner, so constructed that the center burner may operate alone or the center and intermediate burner, or all three burners may operate jointly.

Further objects are to provide a multiple burner construction which is so made that it cannot be extinguished by a transverse current of air as means are provided for maintaining a small light which will re-ignite the main burn- 15 er when the draft is stopped, and which also cannot be extinguished by the overflowing of a vessel on to the burner, as, for example, when a vessel boils over.

Further objects are to provide a burner con- 20 struction in which a plurality of units constitute the burner, and in which a plurality of burners may be arranged in any desired relative position, for example, as that usually found on the tops of gas stoves, and in which pilot light means 25 are provided for each burner, a single pilot light flame for its individual burner being automati- 'cally controlled by the valve for such burner, so that the pilot light is lighted whenever the burner is turned on and the flame projected 30 towards the burner, and thereafter in which the pilot light is extinguished when the main burner valve is turned to a full on position preceding the reverse rotation of the valve.

A particularly important object of this in-' 35 vention is to provide a multiple burner construction in which all of the burner sections, large, medium and small, may be turned down or simmered down at once so that a uniform heating over the entire area of the multiple burner is provided, as, for example, when it is desired to heat a relatively wide bottom vessel or utensil. Thereafter all three sections can oe turned on in full force, or, if it is desired to turn down r all three sections at once, it is done by turning the main movable member towards the oil position. When a smaller area of the burner is desired, it may be accomplished-by turning the main movable member further to the off position.

P Then the outermost section is turned oil. com-, pletely and the medium and small sections slowly increase to a full flame. Said medium and small sections can also be turned down or simmered simultaneously. By further turning. the main movable member to the off position, the medium section is turned off completely and the small section slowly increases to a full flame and can also be turned down or simmered to a minimum. means of a single valve.

All these results are obtained by Further objects are to provide a valve construction for a multiple section burner which is so made that seating of the valve is insured, and which is provided with a plug or other member relatively movable with respect to the main movable valve body and held in engaging position by means. of a spring or similar member, such last member controlling the pilot light in an automatic manner, and also to provide means associated with the valve which insures a click when the successive burners are turned on and when at least two of the burners are turned off.

Further objects are to provide a construction which is easy to manufacture and. assemble, which is inexpensive, and which has a relatively small number of parts.

An embodiment of the invention is shown in the accompanying drawings, in which:

Figure 10 is a sectional view on the line of Figure 11.

Figure 11 is a sectional view through the pilot Il -l4 Referring to the drawings, it will be seen that a gas stove has been indicated generally by the reference character I and the supply main or supply pipe by the reference character 2. A plurality of burners are positioned in any suitable arrangement, for instance, in the spaced arrangement indicated in Figure 1. Each burner is a multiple section burner and consists of a. central burner section 3, an intermediate burner section 4, and an outer burner section 5. These burner sections are joined in an integral manner by webs, as shown in Figure 1, and are preferably spaced apart to provide a free air supply between the burners. These burner sections are supplied respectlvely through the supply pipes or mixture tubes 6, 1 and 8, respectively. The burner tubes or passageways are formed in a single manifold indicated generally by the reference character 9. Obviously these manifolds may be made of any length desired to accommodate the particular positioning of the burner, as indicated in Figure l, and it is intended that the mixing tubes or chamhere 6, and 8 be arranged in the horizontal plane as indicated particularly in Figures 1 and 2.

A pilot light is provided and is indicated generally by the reference character ID. This pilot light is provided with a. casing II which is equipped with holes l2 directed towards the respective burners and located in its side walls. It is also provided with upper ventilating holes l3 and with lower air inlet holes l4.

The pilot light comprises a conical body portion I5 which is provided with a central aperture or passageway IE to which a constant supply of gas is furnished by meansof the pipe I! which, as may be seen from Figure l, is directly connected to the supply main 2 or supply mani fold and is controlled by a permanently adjusted valve l8.

In addition to the central aperture IS the pilot light is provided with four inwardly and upwardly slanting passageways l9, see Figure 11, which are connected to the supply pipes 20 hereinafter described. Each of these upwardly extending passageways I9 is provided with a lateral outlet 2| in line with the appropriate opening l2 and pointing toward its corresponding burner. In other words, where four burners are used, four openings 2| are provided and four independent supply pipes 20 are furnished.

The central aperture 6 is provided with trans verse branch apertures 22 which open outwardly at points intermediate the apertures 2| so that the constantly burning small flames from the apertures 22 will ignite any one of the gas streams which may pass from the apertures 2| in a manner hereinafter to appear.

Referring to Figures 2, 8 and 9, it will be seen that each burner is supplied with a gas nozzle 23 which opens into a vertically enlarged chamber 24. This chamber communicates with the appropriate passageway 6, or 8 and is closed by means of a plate 25, see Figure 9, provided with an aperture 26 which may be more or less closed by an adjustable, slidable plate 21, such plate being locked in adjusted position by means of a screw 28 passing through a slot in the plate.

The nozzles are carried by the three gas supply pipes 29, 30 and 3|, as most clearly shown in Figure 2. The smallest aperture nozzle is carried by the pipe 29, the medium, by the pipe 30, and the largest, by the pipe 3|. The mixing tubes 6, 1 and 8 are also of successively increasing size. The gas supply pipes 29, 30 and 3| are integrally formed with the body portion or main casing 32 of the valve.

The valve comprises the casing 32, the body portion of which is equipped with three main ports 33, 34 and 35 communicating respectively 5 with the pipes 29, 30 and 3|, see Figures 3 and 4.

It is also provided with a port 36 which is preferably formed in a threaded projecting member 31, see Figures 1 and 2, which in turn is connected with its appropriate supply pipe 20 leading to the pilot light and communicating with the aperture 2|, see Figure 11, which is directed towards the burner having the valve under consideration.

The casing 32 is also provided with a port 38 formed in a threaded projecting portion 39 and 15 screwed into the supply main 2, as shown most clearly in Figure 3. The casing is provided with shoulders or stops 40, see Figure 2, which cooperate with a pin 4| carried by the movable portion 42 of the valve to limit the valve in its two 20 extreme positions. Preferably a cap 43 is screwed upon the projecting end of the casing 32 or body portion of the valve and is provided with a spring 44 hearing against the movable member 42 of the valve. Obviously the movable member 42 could be made in other shapes than that de-. scribed, but in the form shown it is of a conical contour and the casing 32 or body portion is correspondingly bored out. rigid with the valve and is provided with a manipulating handle 46.

The movable member 42 or plug of the valve is provided with a central aperture 41 which terminates in a conically bored portion within which latter a conical plug or auxiliary movable member or valve 48 is fitted. This member 48 is held in place by means of a spring 49 which bears against a plate 50 at one end and which bears at the other end against a cap 5| slidably fitting within a sleeve 52 forming an integral extension of the member 48. The plate 50, as may be seen from Figure '7, is provided with a central rounded portion 53 and with a projecting notched portion 54 which latter fits over a projecting arm 55, such arm having an inwardly extending por-' tion bearing against the cap 5|, as may be seen from Figure 2. The portion 53 is joined to the portion 50 by means of a neck' 50'. Thus it will be seen that the member 48 is spring pressed into gas-tight engagement with they member 42 and 50 is movable relative to the movable member 42.

The plate 50 is provided with an aperture 56, see Figure 7, and the end of the member 42 -is provided with a wedge-shaped or cam-shaped nib or projection 51. This projection is provided to cause a click in cooperation with the plate 59 as the valve is turned, Upon the opening motion of the valve, which is a counterclockwise direction as viewed in Figure 7, the first click occurs when the projection 51 strikes the plate 59 and raises it. This corresponds to the opening of the central burner supply. The next click occurs when the projection 51 snaps into the aperture 56, which corresponds to the subsequent opening of the gas supply to the intermediate burner section. The third click occurs when the projection 51 passes from beneath the plate 50, which corresponds to the subsequent opening of the fuel supply for the outermost burner. Upon closing there are three distinct clicks in the reverse 70 manner to that described, as is apparent from an examination of Figure 7 in conjunction with Figure 2.

The member 48 is provided with a .port or aperture 58 which registers with a corresponding port 75 The valve stem 45 is aoaaave or aperture 59 in the member 42, as most clearly shown in Figure 5. The member 42 is provided with an annular channel 60 in permanent communication with the port 59 and which, when the member 42 is turned, communicates with the pilot outlet port 36.

The main movable member 42 of the valve is also provided with an annular tapering port or aperture 6|, see Figures 2 and 3. This aperture communicates with the inlet aperture or port 38 as the valve is opened, that is to say, as it is turned in a counterclockwise direction, as viewed in Figure 3. Thus the supply port 38 is placed in communication with the central apertme 41 of the main member 42.

The annular tapering port or aperture 6| is located so that the narrow end of the aperture 6| is in communication with the aperture 38 when gas is fed to the innermost burner section 3, and the widest part of the aperture 66 'is in communication with the aperture 38 when gas is fed to all three sections of burner 3, 4 and 5.

Thus it is easily understood that the annular tapering port or aperture 6| serves as a regulator for the amount of gas required for the various sizes of the multiple burner sections. For instance, when all three sections of the multiple burner are turned on in full force, the largest amount of gas is required for a suflicient supply to all three sections. At this time the widest part of the aperture 6| is in communication with the aperture 38, and when the intermediate and innermost sections 4 and 3 are turned on in full force, then the center part of the aperture 6| is v in communication with the aperture 38, and when the innermost section 3 is turned on in full force, then the narrowest part of said annular tapering port or aperture 6| is in communication with the aperture 38.

It is easily understood that the manner of forming the aperture 6| causes such aperture to serve as a regulator of gas to all three multiple burner sections 3, 4 and 5.

The main member 42 is further provided with a plurality of radial apertures or ports 62, 63 and 64, as shown in Figures 2 and 4. It is to be noted from Figure 2 that a small flattened portion is formed on the plug member adjacent the outer side of each of the apertures 62, 63 and 54.

As the valve is turned on, that is, in a counterclockwise direction, as viewed in Figure 4, the aperture 62 first registers with the aperture 35 and the innermost burner is thus supplied with fuel. Further turning of the valve causes the aperture 63 to register with the aperture 35 and the aperture 62 to register with the aperture 343. Still further turning of the valve causes the aperture 63 to register with the aperture 35 and the apertures 62 and 33 to register respectively with the apertures 33 and 34.

However, the apertures 82, 63 and 6 upon reverse rotation, that is, closing motion of the valve in a clockwise direction, as viewed in Figure 4, cause first a simultaneous decrease in the fuel supply to all of the burner sections, without, however, completely extinguishing any burner due to the fact that there is a slight overlap between the movable and the stationary apertures or ports, and also due to the slight'flattening of the plug adjacent the outer portions of the apertures 62, 63 and 64, as indicated at 63 in Figure 2.

However, after the aperture 62 has left the aperture or port 33, the outermost burner is extinguished. and the apertures 63 and 62 gradually register fully with the apertures 3d and 35, and consequently the flames of the intermediate burners gradually rise to full height.

Upon further closing motion of the valve, the v apertures 63 and 32 gradually move from the ports 34 and 35, thus decreasing the fuel supply to the intermediate and innermost burner, thus causing them to simmer-down. Subsequently the intermediate burner is extinguished and the central or innermost burner again is gradually provided with full fuel supply. This burner may be dimmed by further closing motion of the valve and may be finally extinguished when the valve is completely closed.

The operation of the valve is as follows: Assuming that the valve is'in its cut off position, as shown in Figures 2 to 7, and assuming that the valve is turned in a counterclockwise direction, as viewed in Figures 3 to '7 (the opening movement), it is apparent that gas is admitted to the central chamber 47 of the valve at the early portion of this motion. In addition gas is admitted to the pilot light port 36. The pilot light for this particular burner is thus projected towards the burner. Continued motion of the valve admits gas first to the port 35, at which time the central burner will be lighted. Upon further motion, the next burner is lighted, and upon completion of the motion the final or outer burner is lighted.

In addition to this, the sleeve 52, see Figures 2 and 7, which is approximately semi-circular,

strikes the projecting neck 55 and rotates the movable member or auxiliary valve 48 with reference to the main valve 82, thus cutting ofi communlcation between the ports 58 and 59, see Figure 5. This extinguishes the pilot light for that particular burner. The steady pilot light furnished by the pipe ll of course burns continuously.

If only one burner is desired, the valve is rotated in a clockwise direction, as viewed in Figures 3 to '7, until only the central burner is supplied with gas, as will be apparent from the previous description and from these figures. If two burners are desired, it is obvious that this may be readily secured. or if all three burners are desired, this also may be readily obtained. It is to be noted, however. that all of the burners may be simultaneously simmered down. as, stance, when a relatively wide utensil is placed over the burner and only a moderate uniformly distributed heat is desired.

After the outermost burner vious that the flames cf the main burn-er will begin to rise is cut off, it is obintermediate and gradually to a full for inr flame and these may then be simmered down. r

and arranged in any desired position, such, for

instance, as shown in Figure 1, and that the individual pilot light tubes 20 will be run one from each valve to its appropriate portion of the pilot light as previously described.

Means are provided for preventing the complete extinguishing of the burner from a crossdraft, for example, or from the boiling over of liquid and the temporary flooding of the burner. These means are very easily provided by forming what is in effect a small Bunsen burner consisting of a channel-shaped plate 65 secured by means of a screw or other member 66 to an upwardly projecting portion 61 integral with the innermost burner and provided with an outwardly directed discharge orifice 6B in line with the horizontally projecting portion of the channel-shaped plate 65.

This channel-shaped plate extends downwardly as indicated at 65 in Figure 13, preferably into the central opening 69 of the innermost burner so that it secures a fresh air supply, such air passing around the sides of the projection 61, as is obvious from Figure 14. It is apparent, therefore, that a cross-blast of air, though it might blow out the flames from the burners, nevertheless will not blow out the shielded flame beneath the plate 65 and from the orifice 68. Consequently when this blast of air ceases, or when the flooding of the burner ceases, due to the overflow previously mentioned, the burner will be re-ignited in an automatic manner.

It is to be noted from Figures 1 and 13, that a series of small holes 65" are formed in the burner section and are arranged in line with the aperture 68 (Figure 13) so that the flame is carried from burner section to burner section.

It is to be noted from Figure 13 that the burners may be provided with outlet apertures either vertically or at an angle as desired.

It will be seen that a very economical form of multiple burner and associated valve has been provided by means of which one or more burners may be automatically lighted from a single control valve and may be turned on either succes-' pletely cut off.

It will be seen further that the auxiliary valve, or auxiliary movable member with reference to the main movable member, is automatically positioned by the operation of the main valve or main member without any thought on the part of the operator so as to properly control the pilot light.

It will be seen further that the entire device is of simple and sturdy construction and may be easily and cheaply made and installed.

Although this invention has been described in considerable detail, it is to be understood that such description is intended as illustrative rather than limiting, as the invention may be variously embodied and is to be interpreted as claimed.
