A further object of the invention is to provide a valve device of the abov'e-mentioned'character, which will prevent the flow of gas to the burner until the thermostatic element has been heated, and will automatically cut oil the flow gas to the gas burner when the thermostatic element cools ofl. Other objects and advantages of the inven-' tion will be apparent during the course of the following description.
of this specification, and in which like numerals are-employed to designate like'parts throughout the same,
' Figure 1 is a central vertical section through a valve device embodying my invention, associated, elements being shown partly in section and partly in elevation, and the automatic valve element. closed.
Figure 2 is a similar view showing the automatic valve element open.
1 s Figure 3 is a detail horizontal sectiontaken on line 33 of Figure 2;
In the drawing, wherein for the purpose of,
illustration is shown a preferred embodiment of my invention, the numeral 5 designates a gas burner element, of any well known or preferred construction, and preferably of the annular type for affording a central passage 6. This gas burner element has a gas mixing inlet tube 7. The numeral 8 designates a gas supply pipe extending along shown). I
My valve device embodies a casingf9,-shown as vertically arranged for the purpose of illustratio'n. I This casing has an outer exteriorly threaded tubular nipple 10, for engagement within an opening formed in the gas supply pipe 8, and a second exteriorly threaded tubular nipple 11, disposed opposite to the nipple 10, for engagement within an opening formed in the end of the gas mixingtube 7. The nipple 11 is stops.
In the accompanying drawing, forming a part the front of the stovev (not of a substantial length so that the valve device may be applied to difierent makes of stoves, wherein the distance between the pipe 8 and the gas mixing tube 7 may vary. within limits. The nipple 10 leads .into a downwardly tapering chamber 12, the inner wall of whichconstitutes a seat for a rotary manually operated valve element 13. The valve element 13 also tapers downwardly and. is provided in its lower end with a recess 14, in communication with a lateral port 15, adapted to be moved into and out of registration with the bore of the nipple 10. The turning movement of the valve element 13 is limited by a pin 13', carried thereby, operating within a groove 14, formed in the casing 9, and adapted to engage walls 15.; constituting The ar'rangementissuch that the turned movement of the valve element in one direction is limited when port 15 is brought into registration with the bore of. the nipple 10, and its turning movement is limited in the opposite direc tion, when the port 15 has been brought out of registration with the bore of this nipple and has moved a short distance therefrom. The manually operated valve element 13 is turned by a. stem 16, having a crank or handle 12?. This stem passes through an opening 18, in a cap 19, screw threaded upon the top of the casing 9. A compressible coil spring 20 is arranged between the cap 19 and the valve element 13, and serves to retain the valve element upon its seat. Thecasing 9 is provided with a lower chamber 21,,in communication with the upperchamber 12, through a passage 22, formed in a web 23. The casing is.provided in its lower end with a vertical opening or passage 24; slidably receiving the stem 25 of an automatic valve element 26. This valve element, when in the raised or open position, projects into the recess 14 'of the manually operated valve element 13, and when in the lowered or closed position, it covers the opening or passage 22, engaging the wall of this opening as avalve seat. The lower chamber 21 is in communication with the bore of the nipple 11. At its lower end, the casing 9 has an annular depending flange 27, affording a. recess 28. Thisrecess receives a head or disc 29, secured to the lower endof the automatic valve stem 25, by any suitable means. A light co'mpressible coil spring 30 engages above this disc and serves to aid in closing the automatic valve,
and preventing the same from 'stickingin the mally adapted to close by-gravity.
Thermostatic means are provided to open the open position, this automatic valve being n surface with fins 35. The upstanding arm 33 is provided atits free end with an outwardly projecting an'nular flange 36, for engagement with an inwardly projectingannular flange 37, carried by a coupling 38. This coupling has screw threaded engagement with the depending flange 27. A flexible diaphragm 39 ,is provided which is preferably formed of rubber, although other material may be used, such as leather, or the like. If the diaphragm is formed of rubber, it will be resilient and expansible. The diaphragm is normally flat and is provided with a thickened marginal portion 40, adapted to be clamped betwen the flanges 36 and 27, and is thereby securely held in place. These marginal edges also serve as packing for the coupling 38, and associated elements.
The numeral 41 designates a. pilot light of any well known or preferred construction, arranged toproject a flame across the burner element 5,
and to impinge upon the bulb 34. Any suitable expansible gas or liquid may be contained within the tube 31, and I have found that highly satisfactory results are obtained by using air as the expansible or thermal medium. However, I may employ any thermal liquid or gas.
The operation of the device is as follows: When it is desired to light the, burnerelement 5, the manually operated valve element 13 is first turned to the open position to bring port 15 into registration with the bore of the nipple 10. At this time, the automatic valve element 26 is in the closed position, and the gas cannot now pass to the burner element 5. Before the pressure therein, which pressure is'transmitted to the diaphragm and the diaphragm is now bowed upwardly. The upward movement of the ,diaphragm raises the disc 29, which in turn, will unseat the automatic valve element 26. The gas will now be free to pass to the burner element 5, and will .be ignited by the pilot light, as is well known. Should the 'pilot light be extinguished before the burner element 5 is lit, the bulb 34 will quickly cool 011, and the pressure will be reduced in.the tube 31, and .the diaphragm 39 will automatically descend and the automatic valve element again seated. If the burner element 5 should be lit, heat therefrom will retain the bulb 34 suitably heated, whereby pressure is maintained within the tube 31 for retaining the automatic valveelement unseated, so that gas may continue to-flow-to the burner element, but if the flame of both the burner element and the pilot should be extinguished,
the pressure will quickly drop in the tube 31', and the automatic valve again seated, to cut off the flow of gas to the same.
It is to be understood that the form of my invention herewith shown and described, is to be taken as the preferred example of the same, andthat various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of my invention, or the scope of the subjoined claims.
Having fully described my invention, what I claim is:
.1. A valve device comprising an elongated casing having a pair of laterally extending tubular nipples, said casing being provided with a transverse web dividingthe same into inlet and outlet chambers, said webhaving a valve seat forming a passage-adapted to place the chambers in communication, the inlet chamber being adapted to communicate with the bore of one nipple and the inlet chamber having communication with the bore of the other nipple, a rotary manually operated valve disposed within the upper chamber and having a recess formed in its lower end and also having a lateral port to be shifted into and out of registration with the bore of the adjacent nipple, an automatic reci rocatory valve' element separate from the rota 'valve element arranged above the web and adapted to engage the valve seat and cover the passage, said recipro'catory valve element being movable into the recess of the rotary valve, a stem secured to the automatic valve element, a flexible diaphragm to move the stem, and a tube for holding an expansible fluid having one end adjacent to the diaphragm.
