The member 46 ex beneath the frame member H and to which a‘ tends into the chamber 29 and has its inner end supply pipe I6 is rigidly secured, preferably by‘ portion beveled, as at 48, to provide a valve seat. 60 lugs or ears i6 rigid with the pipe I5 and fas Within the chamber 29 there is a valve member 2, 105,453 2 which is seated one end of a coil spring ‘I5. The spring ‘I5 surrounds the plunger member 49 which cooperates with the‘ seat 48 and which is supported for universal movement by one end of an operating member or lever 59. The valve ‘I3 and at its other end engages a packing disc or ring 11 seating on the wall 3|. In the ‘wall 3| there is an annular packing material recess ‘I8 which opens into the chamber 39 and which surrounds the free end of the plunger member ‘I3. The recess ‘I8 contains suitable packing ma terial which serves to seal the aperture 32 around member preferably comprises a valve disc . 5| tightly clamped between opposed peripheral ?anges on hollow nut and screw members 52, 53. Within these hollow members there is a support ing pin 54 having a conical head or end portion which seats against the member 53 and which is . the plunger ‘I3 and which is held in the recess 10 10 normally held thereagainst by a coil spring 55 and under compression by the packing ring ‘ll surrounding the pin 54 and held under compres and the spring ‘I5. The plunger member 13 has a longitudinal bore ‘I9 in which an operating sion'between the nut member 52 and the head of the~ pin 54. The pin 54 projects through an aperture in the nut member 52 and is rigidly _ member 89 is reciprocably mounted. The mem ?xed, as at 55, to the lever 59. Adjacent its other ‘ ber 89 projects from the end of the plunger mem 15 ber ‘I3 and is normally held in‘ its outward or end the lever 59 has substantially parallel op posed ?anges 51 projecting from the side edges extended position by a resilient cushioning spring of the lever and toward the plate member 33. 8| positioned in the bore ‘I9. Outward movement of the member‘ 89 is limited by a head portion The ?anges 51 are provided with aligned aper 82 cooperating with an annular shoulder in the 20 tures to receive the end portions of a supporting bore ‘I9. The member 89 extends into the cham shaft 58 which-is mounted in substantially par allel spaced lugs‘ or ears 59 projecting from the ber 29 for cooperation with the lever 59 and is inside face of the plate member 33 and positioned operable upon‘ expansion of the chamber 58 to between the ?anges 51. The shaft 58 serves as engage the lever 59 on the opposite side of shaft, 58 from the valve member 49. The member 99 25 a fulcrum for the lever 59 so that the valve is preferably provided with a conical end por member 49 is pivotally supported for movement toward and from’ its seat. The valve member tion adapted to seat in a'conical recess 83 formed 49 is normally urged toward closed position by in the lever 59., Through the plate member 55 a’spring 59 which is coiled about the shaft 58 there is a passage 84 which opens at one end into the chamber 58 and which at its other end opens between the lugs 59 and which has its end por 30 into a passage 85 in a boss 85 projecting from tions engaging the inside face of the plate mem ber 33 and the underside of the lever 59 on the the plate member 55. The passage 85 connects opposite side of the lever fulcrum from the valve to a tube '81 which ‘extends to the controlling pilot burner 29. The free end portion of the member 49. Through the wall of the casing 28 there is an tube 81 serves as a bulb element, preferably being ' 25 30 wrapped or coiled, as at 88, around the burner 29 and is secured in position by a clamp 89. The tube 81 and chamber 58 comprise a power-means or thermostat and are charged with a. suitable internally threaded bore 5| positioned above the chamber 39 and opening into the chamber 29, being preferably aligned with the bore of‘, the outlet member 35. 20 Adjustably screw-threaded volatile liquid which will expand and contract in to‘ response to change of temperature. After the . ' stem within the chamber 29 there is a head por- , tube and'cliamber have been charged, the end of tion 53 cooperable with the lever 59 and-serving the tube 81 is closed and sealed, as at 99. The as a stop or abutment member to limit opening casing 28 has a depending tubular extension 9| 45 which provides an inlet passage to the chamber 45 movement of the valve member 49. The bore 29.‘ The extension 9| seats on and communicates 5| is sealed around the stem 52 by packing ma terial 54 held under compression by a packing with the branch pipe 5to which it is secured by ' nut or sleeve '55 screwl-threaded in the. outer end a sleeve nut 92. . r The operation of my apparatus is as follows: of the bore 5|. It may be noted that the stem 52 may be screwed inwardly so that. the head . The pilot burner 9 is ignited andthe size of .40 in the bore 5| there is a stem 52 having its ends projecting from the bore. On the end of the portion 53 will engage the lever 59 and hold the valve member to; its seat to prevent ?ow through the‘casing. . _ '1 ' the ?ame is regulated by the valve I3 ‘so as, to provide sumcient ?ame to ignite the main burn I er8andthegasissuingfromtheports23 inthe The chamber'39 has an open side which is closed and sealed by a. plate member 55 which is ' substantially parallel to the plate member 33 and which is secured to the'casing by screws 51. Within the chamber 39 there is an 'expansible collapsible pressure responsive chamber 58 pref erably formed ‘by a substantially cylindrical metal bellows 59' having one end secured and sealed, 'as at ‘I9, in an annular groove or recess formed in the inside face’bf the plate member 55. The other end of the bellows is closed and sealed by a head member or end wall ‘II having a reentrant » portion ‘I2 which extends into the chamber 58 and cooperates with the plate member 55 to limit collapseof the bellows 59. The head member ‘I| rigidly supportsa plunger or- operating'member ‘I3 which is preferably screw-threaded or. other igniter tube ~2| . If the thermostat 21 now closes the circuit through the valve 24 to permit ?ow through the conduit |5I to the pipe l5, the gas will ?ow ‘through the igniter tube 2| and also be discharged from the pilot burner 29. The gas issuing from the ports 23 in the igniter tube will ' be ignited adjacent the constantly burning pilot 60 ‘9, and due to the close proximity of~the ports 23 the ?ame will carry down the tube 2| until the gas issuing from the ports '23 adjacent the burner 29 is-ignited, when the burner 29 will be ignited thereby. Ignition of the burner 29 will 65 heat the volatile ?uid in the coil or bulb 88 and ' create a pressure transmitted through the tube 81 into the chamber 58. The pressure._;thus cre ated in the chamber 58 wilhexpand the, bellows 59 against the foree of spring ‘I5. As the plunger 70 wisesecured in a substantially cylindrical recess ' member ‘I3 moves outward-rand into the chamqj _. 14 in the member ‘II and portion ‘I2. Adjustably ' ber 29, the operating member 85 will engage the-'7 ‘ screw-threaded on the plunger member 13 there is an abutment member ‘I5 preferablyin the form 75 of a sleeve having an annular ?ange against lever 59. Continued movement of the plunger member ‘I3 as spring ‘I5 collapses will rotate the lever 55 about the slntt 58,-overcoming the light 2,105,453 spring 60 and moving the valve member 49 to ward open position. Opening of the valve mem ber 49 will permit gas to ?ow through the valve 1 into the mixing tube 39 where the gas will be mixed with the proper proportion of air for burn ing at the main burner 8. The gas supplied to the main burner 8 will be ignited by the con stantly' burning pilot burner 9. When the sole noid valve 24 is closed by breaking of the circuit at 10 the thermostat 21, for example, the supply of gas to the controlling pilot burner 20 and the igniter tube 2| will be cut o?. Extlnguishment of the pilot burner 20 will permit the coil or bulb 88 to cool and thereby relieve the pressure in the chamber 68 so that the spring 16 will retract the plunger member ‘I3 and its operating member 80 from the lever 50 to permit the spring 60 to move the valve member 49 to closed position. The ex tent to which the valve member 49 can be opened may be regulated by the position of the head por tion ‘63. If the valve member is limited in its opening movement by engagement of the lever 50 with the portion 63 before the chamber 68 has reached its limit of expansion, then the spring 8| will permit relative movement between the member 80 and the plunger member 13 so that the plunger member 13 can continue to move without injuring the parts of the valve.
