Our invention relates to improvements in valves for gas burners,

The object of our invention is to provide a simple valve controlling the flow of gas to a main burner and a simmer burner and in which a full flow of gas to both burners may be obtained or the flow of gas entirely out ofi.

7 Another object of our invention is to provide a valve of this character in which the flow of gas to the main burner can be entirely cut oif and at the same time maintain a full flow of gas to the simmer burner.

Another object of our invention is to provide a valve of this character in which the flow of gas to the main and simmer burners may be drawn down or decreased to reduce the flame simultaneously at both burners.

Another object of our invention is to provide a valve in which the flow of gas tothe main and simmer burners can be simultaneously increased or decreased to regulate the flame.

A still further object of our invention is to provide a valve of this character in which the same is locked in either the full open or closed position and yet allowing the free turning thereof sothat it can pass from any of the other positions through the full open or closed position without stopping at suchposition.

A still further object of our invention is to provide a valve of this type which is simple in construction and operation and very effective to accomplish the desired results and having certain details of structure and combination of parts hereinafter more fully described.

Referring now to the drawings I represents a valve housing which as shown is of an elongated form having therein a tapering bore 2 which extends from the open upper end 3. The lower end of the housing is provided with a reduced screw threaded end 4 having a passage 5 therethrough, the inner end of which communicates with the tapering bore 2. Screwed on said reduced end is a regulating valve 6 which governs the discharge of gas to the main burner, which will be later described. This valve'6 may be of any desired form as it forms no part of our invention and therefore we will not describe the same in detail.

One side of the valve housing I is provided with an outwardly extending nipple I externally threaded at 8 and upon which is screwed the cap 9 which encloses the operating head III of the regulating valve II. The valve II has an enlarged externally threaded portion l2 screwed into the internal threads I3 of the bore i4. The inner end of the bore I4 is tapered to provide a. seat for valve H, as at l5, and communicates at its inner end with the bore 2 of the valve housing I, through passage [6. The opening I is provided with a passage H which communicates at its outer end with the bore l4 of the nipple 1 and the inner end of the passage communicates with a passage i8 in the. housing which extends outwardly from the bore 2 through the nipple l9 and whereby the bore M has indirectly two communications with the bore 2 of the valve housing. The outer end of the nipple I9 is externally threaded at 20 for connection with the gas manifold 20' and whereby the supply of gas for the valve housing is obtained for feeding the burners.

The passage l8 has communicating therewith an obliquely arranged passage l8 which communicates with the bore of the housing and whereby gas may be diverted directly from the main gas supply to the simmer burners.

The valve housing adjacent its upper open end 3 is provided with a nipple 2| which is externally threaded at 22 for the reception of a coupling I00. The passage 23 allows the gas to pass from the bore 2 of the valve housing I to the simmer burner. Manual adjustment of the simmer burner is efiected by means of an adjustable screw valve |0| mounted on the coupling I00.

Arranged in the bore 2 of the valve housing is a plug valve 24 of a tapering form to snugly fit the walls of the bore as is well understood in valves of the plug type. The lower end of the valve 24 is provided with the open ended bore 25 which extends about half way up through the valve and is provided adjacent its-upper end in one side, with a lateral passage 26 extending through the periphery of the valve. Extending from the upper end of the bore 25 is an obliquely arranged smaller passage 21 which extends through the periphery of the plug, these passages being specifically shown in Figures 23 and 24 of the drawings. The outer periphery of the plug valve is provided with a groove 28 which extends nearly half way through the plug as shown in' bore 29 is a'transverse slot 3|, said slot as shown in Figure 1 being wider on one side of the bore 29 as indicated at 32 than that portion 33 as shown in Figure 21, the purpose of which will be later described. The outer periphery of the plug 24 adjacent its upper end is provided with an annular groove 34.

The upper end of the valve housing opposite the open end of the bore 2 is provided on opposite sides with outwardly extending cars 35 and 36, the inner ends of which are cut away at 31 and 38 forming a guide way for the'latch member later to be described. Fitting in the bore 29 is a coil spring 39, the upper end of which bears against the latch member 40. This latch member as shown in Figure 25 of the drawings comprises a circular body portion having on opposite sides thelugs 42 and 43. The circular center portion is of a diameter to fit within the bore 29 of the upper end of the plug 24 and bears 5 upon the spring 39. The lug 42 carried thereby on the main burner.

32 in the upper end of the plug and is free to move up and down under the tension of the spring. The body portion 4| of said latch is provided with an upwardly pressed nipple 44 forming a bearing for the valve operating rod 45.

The valve operating rod 45 is provided at its inner end with a depression 46 to receive the nipple 44. The valve rod 45 on opposite s des is provided with outwardly extending lugs 41 and 4B, which enter the slots 33 and 32 of the valve plug 24. The lug 41 is of a size to snugly fit the.

slot 33 while the lug 48 is of a larger size to fit the slot 32 whereby the valve rod is held in the valve against rotation yet is free to be forced inwardly longitudinally thereof against the tension of the spring 39. The spring bears against the circular portion 4| of the latch member and the same is normally held in its outward position as shown in Figure 2 of the drawings. In order to hold the valve operating rod against outward movement beyond the slots in the valve plug I provide a cap 49 which is of a saucer shaped form having on opposite sides the outwardly extending ears 59 and 5| to fit on the cars 35 and 36 of the valve housing and secured thereto by means of screws 52 and 53 whereby the cap is held in the position shown in Figure 2 of the drawings. It will be seen by this structure the valve rod 45 is held in position and the ears 41 and 49 carried thereby engaging the under face of the cap the same is prevented from being forced outwardly by the spring 39 so that the lugs will not disengage from the slots in the plug. One side of the cap 49 is cut away as indicated at 54 which together with the cut away portions 31 and 38 of the ears 35 and 36 form the slot which in combination with the latch member 40 forms a snap latch for holding the valve in its several adjusted positions. The wall 55 of the cap 49 extends below the ears and 5| serving as a stop to engage the lug .43 of the latch member and hold the valve in its two extreme positions. It will be seen that the lug 42 is of a length to pass on the inside of the wall while the lug 43 engages the edge thereof.

. The outer end of the valve stem or rod 45 is cut away as indicated at 56 so as to fit a correspondingly shaped slot in the operating handle 51 whereby the same is held thereon against rotation. The handle is held thereon against longitudinal movement by the set screw 58.

The device is.especially designed for burners in'which there is a main burner 59 and a simmer burner 60 within the same, although the exact location of the burners relative to each other do not form a part of the invention as they could be arranged side by side, it being understood that they should be in such relation that the simmer burner will be below the cooking utensil placed In Figure 27 we have shown one arrangement of the, burners. The gas supply manifold 20' as shown, supplies gas to the valve housing I through the nipple l9. The nipple 4 of the housing and its valve 6 extend into the mixing tube 6| of the main burner 59 while the nipple 2| and its valve extends into the mixing tube 62 of the simmer burner 60.

When the valve plug 2 is in the position shown in Figure 4, the opening 26 is opposite the solid wall of the bore and the gas to both burners is entirely cut ofi. When in this position arm 43 of the latch member 40 is in engagement with the wall 54' or station dot the cut away 54 and is held in said position, Turning the plug counter clockwise by the hand the arm 43 of the latch s moves with the same being outwardly spring pressed by the spring 39. When" the arm 43 reaches the slot the spring forces the latch outwardly at wall 63 of station 0 into the cut away portion 54 of the cap and snaps indicating the valve has reached another position. When the plug valve is in this position gas passes through the passage l8 from the manifold 20 and from said passage through the passage I! to the cut away portion not the plug 24. When the plug is in this or full simmer position this cut away portion is also in communication with the passage 23 leading to the simmer burner and a full flow of gas thereto is obtained. The opening 26 in the plug is opposite the solid walls of the bore of the V housing and no gas is'passed to the main burner.

Continued turning of the valve in a counter clockwise direction causes the arm 43 to strike the other end or wall 64' at station E of the cut away portion of the cap 49 and is held against further counter clockwise movement. When in this position the opening 26 in the plug is opposite the main gas supply passage is and a full flow of gas passes through the hollow valve out through bore 25 to the passage 5 to the main bumer. The cut away portion 2Q in the valve plug is of such a length that when in this position it is also registeringwith the passages 18' and 23 and a full flow of gas is passing to the simmer burner.

By depressing the operating handle the latch member to is moved longitudinally in the valve and the arm as is brought in beyond the wall 64 of the cut away portion 54 of the latch and which allows of a continued counter clockwise movement of the handle and plug until the arm 43 strikes the wall 55 at station A of the extended portion of the cap. When the plug has reached this position the opening 26 in the plug is opposite the passage it and gas can pass from the main gas passage it through passage ll and through passage to and opening26 to the hollow plug valve and from there through bore 25 and passage 7 5 to the main burner. Continued anti-clockwise movement of the valve stem gradually closes the plug inlet 26 to inlet l8 but at the'saine time gradually brings inlet 26 into communication with needle valve controlled by-pass passage l6, and until plug inlet 26 is closed to direct com munication with inlet l8 and takes it supply of gas for the main burner through by-pass passages l1 and it. The flow to the main burner is thus gradually reduced to a minimum. During this movement flow of gas through passages 18 and 1.8, cut-away portion or groove 28' and outlet passage 23, to the simmer burner, is gradually reduced by gradually closing communication between groove 28 and. passage 23. At the same time (and before this communication has been shut off and the simmer extinguished) the passage 21 extending through the wall of the hollow plug valve into the bore 25 thereof is brought into, register with the simmer outlet 23. Thus, as the flow of gas to'the simmer is gradually shut oiiE through the'groove 28 in the plug, a correspondingly decreased supply of gas is made available from the supply going through the bore 25 of the plug to the main burner. This uniform and gradual adjustment of flow to both burners is made possible by the arrangement 01' passages mentioned and by reason of the fact that the outlet of passage 21, is sufliciently close to the adjacent end of cut-away portion or groove 28, that the portion or area 15 of the plug separating the passage 21 and groove 23, is not of sufllcient width to at any time close passage 23, and because inlet passage 26 will continue to supply gas direct to the simmer burner through inlet passage 26,.

bore 25 and outlet passage 21, until communication is had through by-pass passages 16 and i1, bore 25 and simmer outlet passage 21. The importance of and necessity for passage 21 is apparent. x

In turning the handle and valve clockwise the arm 43 moves until it snaps intothe cut away portion 54 adjacent the wall 64 at station 3 indicating the full open position giving a full supply of gas to the main and simmer burners. The continued clockwise movement of the handle brings the arm 43 of the latch 40 in engagement with the wall 63 of the cut away portion '54, at station C of the capand stopping the movement therein. This is the position with a full flow of gas to the simmer burner. In order to continue the clockwise movement of the valve by the handle, the

handle is forced inwardly forcing the latch 40 inwardly until the arm 43 is beyond the lower end of wall 63 and the valve can be turned, until the arm 43 strikes the extended end or wall 54 at station D of the cap149. This brings the valve to a full closed position for both burners.

By depressing the handle and holding it against the tension of the spring the valve can be turned to any of the before described positions without stopping at any of the intermediate positions. The same is true in both counter-clockwise and clockwise movements.

It will be seen from the foregoing that when the plug valve has been moved to station A by manipulating the handle 51, and with an equal volume of gas flowing to both the main and simmer burners, under balancedpressure, the heighth of the flames of the two burners will be the same. At this position the volume of the gas flowing to both burners, as well as the heighth of the flames of these burners pan be regulated to and set at any'desired heighth, below maximum, by means of the regulating valve II.

It will be readily understood that whenever the housewife desires to cook with or heat a considerable quantity of liquid the center simmer tains very little liquid, use of the main burner is desirable because the flame is distributed over a considerable area and consequently danger of scorching the utensil or its contents is lessened. From the foregoing it will be seen that gas is simultaneously delivered to the simmer from both of two different sourcesand independently from these two sources. Also that the regulating valve ii automatically regulates the amount of gas which flows to both the main and simmer bumers when the valves have been rotated to lowflame simmer position.
