' 3 cla ms. (01. 277-4) Our invention relates to devices used in the control of gas burners; an object'being in our device to provide a single dial control valve for gas burners. j V

We have for our major purpose in this invention to provide a simple, economical, and practical meansof controlling gas burners of a gas range,

for instance by the control ofone dial in its selective adjustments; wherein the same dial maybe used for the control of anyone of the gas burners one at'a time. .4

We attain the objectsof our invention by the mechanism described in the annexed specification recited in the claims and illustrated in the accompanying drawings in which like reference numerals indicate like parts in the several figures.

Referring to the figures:

Figure 1 is a top View of our invention shown in partial section disclosing details of construction thereof.

Figure 2 is a front view of the control dial of our invention showing in dotted lines and in section the operative relation of the control dial with the gear segments on the valves.

Figure 3 is a top view of our invention shown connected with the leads which run to the gas burners.

Figure 4 is a front view of our invention illustrated in Figure 3.

Figure 5 is a complete horizontal half-section of our invention.

Figure 6 is a detail of the operative gear meshing relations of the valve stem gear segments and the control dial gear segments. This detail shows also the stem of the valve.

Referring now in detail to the construction of our invention and the preferred method of operating the same, we provide a housing I shaped to define a gas receiving chamber 2 and provided with a gas intake connection 3.

To this housing there is detachably connected a plurality of valve casings 4, 5, 6, and I. These valve casings are preferably provided with threaded attachments 8, 9, I0, and I I made integral with the casing.

Operating as a valve in each of these casings a valve stem I2 is provided with one tubular end I3 with an outlet I4 and a valve orifice I5 on one side communicating with the tubular portion of the stem.

On the end of the valve stem opposite the tubular portion there is fixedly secured a gear segment I6 adapted to mesh with and be controlled by a relatively small gear segment ll of a control dial I8 supportably mounted on a shaft I9 and both slidably movable and freely rotatable thereon. I f

This control dial is'retained on shaft I9 by a cap screw 20 while a compression spring 2| 5 mounted on shaft I 9 between dial I8 and housing I is-adapted to normally hold dial I8 out of engagementwithgear segments It on valve stems I2 of the respective valves.

When it is desired to light one ofthe burners 10 22, 23', 24, and 25 then the valve connected with that burner will be manipulated by slidably push' ing in on dial I8 against spring 2| until gear segment I 1 slides into mesh with gear segment I6 controlling the valve which releases gas to that 15 burner. When dial I8 is thus in mesh with the gear segment Iii it is then held in place while rotating the dial to the extent necessary to bring orifice I5 of that stem I2 into registry with the housing gas outlet passage 26 for the valve being 20 used, thus opening the way for the gas to move from receiving chamber 2 to the burner to be lighted.

When the gas enters orifice I5 from chamber 2 through passage 26 it will leave the tubular end 25 I4 of valve member I2 on its way to the gas burner.

It will be observed that by means of our invention any desired adjustment may be made 7 in the size of the blaze in the burner by selec- 30 tively adjusting the position of rotation of orifice i5 in stem I2; thus regulating the amount of gas which may pass through the valve from outlet passage 26 communicating with gas receiving chamber 2. 35

Thus it will be observed that any one of the burners may be lighted and suitably adjusted, one at a time, by turning gear segment I I of dial I 8 around to the gear segment I6 on the valve stem to be adjusted and slidably push: 40 ing in on dial I8 to bring gear I'I into meshwith gear segment I6 of the desired valve so as to rotate the valve connected therewith by turning dial I8 rotatably on shaft I9. This will release the gas for the desired burner from receiv- 45 ing chamber 2 which gets its supply of gas through a feed pipe 21.

Valves 4, 5, 6, and l are connected with gas distributing pipes 28, 29, 30, and 3| which carry the gas to the burners 22,23, 24, and 25. 50

It is conceivable that instead of using distributing pipes 28, 29, 30, and 3| a casting with distributing channels may be used within the spirit of our invention while it is evident that other minor changes in the construction of our 55 device may be made without departing from the scope of our invention.

The salient structural features of our invention having been pointed out and described what we claim is:

l. A single dial control valve for gas burners comprising a gas receiving housing provided with a plurality of valve cylinders, a plurality of communicatively connected spigot valves rotatably registering in said valve cylinders and disposed with the cylinders in circumferential alignment about the housing, an integral valve stem for each of said valves and a gear segmentsecured to the free end of each of said valve stems, a

control dial having a peripheral gear segment adapted to be selectively rotated and slidably moved into mesh respectively with said gear segments for the selective, control thereof, a shaft for the support of said dial and a spring for resiliently holding said dial out of engagement with said valves except when pressure is applied against the spring.

' 2. A gas control appliance comprising a housripheral gear segment and freely rotatable and resiliently supported on said shaft; said valves being each provided with a gear segment and an integral valve stem for the support thereof and each of said gear segments being adapted to selectively mesh, one at a time, with said gear segment of said'dial for the optional control of said valves by the selective adjustment and rotation of said dial.

3. A dial control for multiple gas cocks comprising a housing for receiving gas from a source of fuel supply, a plurality of gas outlet control valve casings spaced from and communicatively connected with said housing in concentric alignment about the housing, a valve'for each of said valve casings provided with a control stem and a gear segment at the terminal thereof, a control dial having an internal peripheral flange pro- "gear teeth of said valve stem terminals for the rotatable adjustment of said valves communicating with said housing;. a fixed shaft supported by said housing,ja compression spring mounted on the shaft and said dial beings freely rotatable on said shaft and mounted so as to compress said spring when in engagement with said gear segments on said valve stems and adaptedto be automatically and slidably moved by said spring out of engagement with said valve gear segments when hand control is released therefrom.
