Application February 4,

Renewed Ju 18 Claims.

My invention relates to improvements in gas stoves, the primary" object of which is to provide a means of lighting any of the burners automatically whenthe valve; which turns on the gas to the burner is operated.

My invention includes a particular cam means operabl with the gas valve having a nature to operatgand and to hold a lighter valve open for a pre etermined period of time in the operation of the gas valve, the purpose of which is to permit the gas to have time to flow to the burner before the lighter gas valve is shut off to insure lighting'of the burner automatically when the valve is opened.

It is also a feature of my invention to provide a simplified operating rod means which is removable in a manner to assemble or disassemble the same in conjunction with the standard parts of the ordinary gas stove and to permit the same to be adjusted. This includes an adjustable bracket member which is formed with bracket extension portions having slidable adjustments and a bifurcated portion for the operation of the lighting rod.

The lighting mechanism includes a strap having a cup adapted to set on the lighter button and carrying a tubular portion on the opposite end which is adapted to adjustably-and remdvably receive the lighter rod which is operated by the valve cams.

An important feature of my invention resides in the operation of the oven burner which includes a double cam means which operate in synchronism, one cam operating the lighter rod and the other cam operating a gas valve which directs a flow of gas adjacent the lighter and extending to the burner to carry a lighting flame to the oven burner, the lighting flame going out as the burner valve is opened and after the oven burner is lit. The lighting of the. oven may also be accomplished by the lighter gas valve cam operating in conjunction with an arm which is. attached to the valve stem and which operates the independent valve, directing the independent flow of gas to the lighter tube for the oven,

the valve directing gas to this tube being formed with a ratchet pawl which operates in one direction to operatethe valve andreleases in the other direction so as not to operate the valve,

0 the valve being closed automatically by spring means.

A further object of the invention resides in an air valve for the burner including tubular means extending through the air chamber of the burner tube arm which is adapted to direct the 1928, Serial No. 251,848 ly 20, 1931 flow of gas into the constricted portion of the burner tube arm, carrying the gas through a tube which shields the flow of the same through the air mixing portion of the burner arm tube.

. These features, together with other objects and details of my invention will be more clearly and fully set forth in the specification and claims which I will endeavor to more clearly define.

Mygas stove ,A is of the ordinary nature and diagrammatically illustrated in plan view to show by the pilot light which is operated automatically by a lighting mechanism D.

The oven burner E of my gas stove is illustrated in its relative position within the oven portion of the stove and this burner is adapted to be automatically lit by the lighting mechanism D in conjunction with an auxiliary lighting valve and tube mechanism F which will be more fully and clearly hereinafter described.

My gas stove A is provided with the ordinary gas feed pipe which extends along the front of the open shelf 11 which includes the burners B, all of which is of ordinary well known construction. The feed pipe 10 supportsthe ordinary gas burner valves 12 which are provided with operating handles 13.

I provide the automatic lighting mechanism D which is adapted to operate the pilot light C and this includes individual cam members 14 attached to the valve stem and operable therewith by each of the valves 12. i

The cams 14 are attached in a manner so that the camoperating surface 15 depends and is elongated with a straight portion 16. These cams are adapted to operate the lighter rod 17 of the mechanism D which extends along below the pipe 10 and the ends of which are guided by the adjustable brackets G which engage with the feed pipe 10.

The adjustable brackets G are formed with a bracket member 18 adapted to engage about the pipe 10 to which I adjustably secure a bracket member 19. A second bracket and guide member 20 is adjustably held to the bracket member 19 through the slot 21 in the member 19 and the screw 22 which extends through the slot. The bracket members G are adapted to be set in a manner so as to guide the ends 17' of the rod 18 so that it may be operated uniformly by the cams 14 of the valves 12. v

The lighting mechanism D includes a strap member 24 which is provided with a tubular portion 25 through which the rod 17 extends and by means of the set screw 26 the rod is held adjusted to the strap member 24. The strap member 24 has a cup portion 27 which fits over the pilot lighter button 28. The strap member 24 may be slotted at 29 to extend on either side of the pipe 30 of the pilot lighter C.

Each of the valves 12-is provided with a cam 14 adapted to operate the rod 17 and in turn through the strap member 24 the pilot light C is operated simultaneously with the operation of the valves 12. The elongated straight surface 16 of the cams 14 on'the operating edge 15 hold the rod 1'7 depressed long enough to keep the button 28 open a sufiicient length of time to permit the gas to flow from the valve 12 to the respective burner B. Thus the burner B is automatically ignited by the pilot light C in the operation of the valve handle 13. It is important that the cams 14 have the long operating surface 16 to hold the 7 pilot light on long enough to permit the burner fined within an inclosure beneath the oven, I

provide an auxiliary gas feed tube 33 in the lighting mechanism F. This tube 33 is connected by the valve 34 with the main feed pipe 10 of my gas stove A and by means of a .cam 35 which is held on the upper portion of the stem of the valve 12, as illustrated in Figures 7 and 9, as the handle 13 of the burner gas valve 12 is operated, the valve 34 for the auxiliary feed 33 is operated, at the same time the cam 14 on the lower end of the stem of the valve 12 of the oven burner gas valve is operated, so that these two cams 14 and 35 are operated in synchronism, one operating the rod 17 of the mechanism D, while the other operates the valve 34. I

. The auxiliary lighting mechanism F is provided with an adjustable extending lighting tube 36 which is held by the set screw 3'? adjustably and as an extension of the tube 33, and which is provided with lighting openings 38 extending to the burner E. The openings 38 are placed in aposition so that when the flame from the-pilot light C is extended they will light the gas from the auxiliary tube 33 through the openings 38 and direct a lighting flame which will run along the openings to the burner E, so that the burner E will be ignited from the auxiliary gas feed tube 33.

The auxiliary valve 34 may be in the form of the valve 40 having a ratchet operating arm 41 which is operated by the arm 42 projecting from the valve 12, as illustrated in Figure 10. The valve 40 is of such a nature as to be provided with a spring43 which isadapted to close the valve automatically after it has been opened in the operation of the arm 42 against the ratchet arm 41. The ratchet pawl 41 is held by a suitable spring 44 into the normal position illustrated in Figure 10 and is connected to the stem 45 of the valve 40 which operates the valve proper by rotating in a direction to open the valve 40 when the arm 42 engages against the pawl 41 in the opening movement of the valve 12, as indicated by the arrow in Figure 10. However, as the valve 12 is shut off and the arm 42 moves in closing position then the ratchet pawl 41 permits the arm 42 to slip back of the same into operative position, as illustrated in Figure 10, Without opening the valve 40. Thus by means of this ratchet valve 40 which automatically closes itself directly after it has been turned on by the arm 42, gas is directed to the auxiliary feed pipe 33 to direct gas only to the lighting openings 38 for the burner E in the opening operation of the burner valve 12.

The mechanism described heretofore such as in the valve 34 is such as to cause the gas to be directed to the auxiliary pipe, both in the opening and the closing operation. There are some cases where the valve 40 is preferred over the valve 34, however, the valve 34 is simple in operation and may be used equally well in carrying out the principles of my invention.

In place of the strap member 24 it may be preferred to use the yoke member I which is provided with a cup 47 similar in function to the cup 27 and strap arms 48 which extend in the form of a yoke to the tubular member 49 which is similar to the tubularmember 25. This yoke is adapted to support the operating rod 1'7 and functions in place of the strap member 24.

My gas stove is provided with an air chamber 2 J as illustrated in Figures 12 to 15 inclusive. This chamber is preferred in the operation of my automatic lighting means for the reason that it includes the essential elements to provide the proper mixture of the gas to direct the gas to the burners B in the proper manner. The chamber J is positioned in the burner arm 50 which extends to the burners B and E and includes a 1 distance into the burner arm tube 50, as illustrated in Figure 12. The tubular member 51 is formed with air inlet openings 54 staggeredly arranged in the tubular'member 51 and adapted to draw air from the mixing chamber 53 and in a short portion of the burner arm by means of the gas coming by force from the burner jet 55. i

* The chamber J is an important feature in carrying out my automatic lighting means as hereinbefore described because it is necessary to provide the burners B and E with such means of directing the gas to the small portion of the burner arm 50 without back-currents in the enlarged mixing chamber 53. The restricted tube 51 extending from the plate 52 permits the gas jet 55 which leads from the feed pipe 10 -to direct a fine stream of gas under pressure through the pipe 51, setting up an intensified vacuum, causing air to be drawn in through the openings 54 and forcing the mixture of the air with the gas from the tube 51. Thus more uniformly mixing thegas and air in the proper proportions 'and preventing the back-firing of E and provides a more eflicient mixing of thegas and air so that a smaller amount of gas is necessary in the operation of the burners B or E,thus giving a construction to my gas stove A wherein a more economical means of operation is provided.

My gas stove includes the features set forth and I have found that each of these features eo-operate together in such a manner as to provide a gas stove of a very desirable nature, having the safety means of preventing the burners from being turned down without being lit, protecting children in the home and overcoming the back-firing of the burners or small explosions, particularly in lighting the oven which are so apparent where the gas is turned on and the burner is not lit at the proper time. Each burner is automatic and can be operated by one hand, the burner in the oven lighting just as readily as any of the burners B. The easily attached and adjusted members are also an im portant feature of my invention.

Inaccordance with the patent statutes I have described the principles and particular construction of the elements and combination of the parts of my gas stove and while I have illustrated a particular formation, I desire tohave it understood that the same are only illustrative of a therefor, a valve for said auxiliary gas feed tube,
