4 Claims.

The object of my invention is to provide a stove of the type using gasoline under pressure or the like, which is provided with a plurality of burners and which has a push button lighter, whereby all but the master burner may be conveniently and easily lighted from the master burner.

Another object is to provide such a structure in which a pilot light may be eliminated.

It is my particular object to provide a novel and inexpensive and eiiicient structure in such a lighter device.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of my push button lighter, wherebythe objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawing, in which:-

Figure 1 is a top or plan view of a burner equipped with a push button lighter embodying my invention, parts being broken away and parts being shown inv section.

Figure 2 is a detail, sectional view taken on the line 2-2 of Figure 1.

Figure 3 is a detail, sectional View taken on the line 3-3 of Figure 2; and

Figure 4 is a detail, sectional View taken on the line 4 4 of Figure 2.

I shall first describe in a general way the burner structure. The burner manifold is indicated generally at A, and is of peculiar irregular form, varying according to the number of burners proper with which the stove is equipped and varying with other features of stove construc' tion.

The manifold here illustrated is a hollow one with a transversely extending portion I6. From the manifold portion I6 extend the passages I1, I8, I9, and 20 to four burners with which the stove is provided. Three of the burners are indicated at Ila, l8a, and 20a.. The burner 20a, is the master burner.y The burner connected with the passage I9 is omitted but is like the others. v

An intake passage 22 leads to the manifold portion I6 and another passage 23 leads from the manifold portion I6 to the passage 24 to the generator burner 25 of the ordinary saw-kerf type.

Arranged above the generator burner 25 and communicating with the intake passage 22 is a generator 3|. Fuel is supplied to the generator 3l and thence to the manifold through a valve 1935, Serial N0. 27,201

43, which is automatically controlled by means of a thermostat 44.

Valve control rods

63, 64, 65, and 66 and ordinary valves not shown in detail, control the flow of fuel from the fuel manifold to the various burners. A valve 40 controls the flow of fuel from the generator to the manifold.

In Figure 1, I have shown at 10 what may be called the generator burner lighter'. It is similar in construction to parts of the push button lighter to be later described, and will` be referred to again. It is suflicient for the present to say that this burner lighter 'I0 is of such construction that when the valve 40and the valve controlled by rod 63, are opened, and the master burner is lighted, fuel will pass to the generator burner 25 and thence upwardly through the lighter 10, where it will be lighted by the flame from the master burner 20a and flame will then pass down through the lighter 'Hl to the generator burner for igniting the fuel escaping from the generator burner.

I shall now describe in greater detail the push button lighter structure.

Communicating with the manifold section i6 is a tubular elbow tting 14, best shown in Figure 2.

At the inner end of the fitting 14 is a valve seat 15 with which coacts a disc valve 16 on a stem 'Il slidably projecting through the wall of the iitting i4 and then extending toward the front of the stove, and provided at its outer end with a push button head 78.

On the stem 11 'spaced from the fitting 'M is a fixed collar 19. A coil spring 8l] is arranged on the stem 1l between the collar 'I9 and the fitting 'i4 under compression, so that it normally holds the valve 16 tightly seated.

By pressing the head 'I8 inwardly against the tension of the spring 80, the valve 'i6 can be opened for allowing fuel vapors to pass from the manifold into and through the fitting 14.

The burner lighter structure now to be described can be assembled as a unit, and set onl the upper end of the fitting 14.

This lighter structure includes a sleeve 8l, telescopically receiving the upper end of the fitting lil and having a top 82 spaced above the fitting 14, and provided with a series of small perforations 83.

The tube 84 communicates with the interior of the sleeve 8| near the top thereof and extends slightly downwardly to position close to the generator burner 25.

Similar tubes 85 communicate with the upper interior of the sleeve 8l and extend to the other burners.

The

tubes

84 and 85 have in their tops longitudinal narrow slots 86.

The outer end of the tube 84 is closed as at 84a, while the tubes 85 preferably have filter screens 81 at their outer ends. The tube 84 has a downwardly opening, channel-shaped hood 88 receiving the tube 84 between its lower side walls, as shown in Figure 2. The tube 88 is open at its lower end adjacent the generator burner 25. The tubes 85 have substantially similar channel-shaped hoods 89 partially receiving them and partially above them. The hoods 89 are substantially closed at their outer ends as at 90. y

Each hood 85 has at its outer end at itstop, an opening 9|.

On the top of the sleeve 8| is a cap 92 having an annular, downwardly extending flange 92a provided with an internal shoulder .93 -restin'go'n the top 83. The flange 92a extends downwardly and forms an apron around the upper part of the sleeve 8|. In Ythe flange 92a is a series of notches 94 to receive the ends of the hoods 88-89. The cap 92 is held in place on the sleeve 8| by means of a screw r95 extended through the cap and screwed into the top 82.

The generator lighter 10 shown in Figure 1 is similar in general construction to the lighter members already described, having an interior tube similar to the tubes 84-85, its lower end being closed as in the case of the outer end of the tube 84, and its upper end having a screen as in the tubes 85. The lighter 'I0 has an outer hood similar to the hood 89.

Operation of push, button lighter Until the valve 16 is opened, the push button lighter ordinarily performs no particular function. Assuming, however, that the generator burner 25 has been lighted from the master burner in the way heretofore described, then the push button lighter may be used lfor the purpose for which it is intended. In this connection. it may perhaps be mentioned that the tube 84 and hood 88 could be connected with the Vmaster burner instead of the generator burner if that were desired. It might also be mentioned that one reason for lighting the master burner 20a instead of the generator burner in starting the stove is that the burner 20a is conveniently accessible when a dirt tray is in place over the burner, whereas the generator burner is not then readily accessible for lighting.

When it is desired to light any one of the other burners (Ila, |8a or |9a) from the burner 25, the operator simply pushes on the head 18 and opens the valve 16 (see Figures 1 and 2) Thereupon gas or fumes from the manifold section .I6 pass through the fitting 14 into the sleeve 8l and thence through the various tubes 84-85 to the various burners. Gas escaping from the lower end of the tube 84 is ignited from the flame of the burner 25 and then the flame follows along under the hood 88 which guides the flame along the slot 86 and prevents its blowing away. The flame then passes into the cap 92, and then passes to all of the other burners (Ila, |8a and |9a) and if either of the valves controlled by the

rods

64, 65 or 68 is open, the fuel escaping from the corresponding burner will be ignited.

I have thus provided a rather simple and very efficient structure whereby after the master burner is lighted and the generator burner is burning, any of the three other burners mentioned may be lighted almost instantaneously and very easily by pushing in on the button or head 18.

It may be mentioned that the sleeve 8| can be simply lifted off the fitting 14 and the assembly including the sleeve 8|, cap 92, tubes 84-85 and hoods 88-89 may thus be removed or installed as a unit.

It Will be obvious that I have provided a very simple and inexpensive push button lighter, by which any of the other burners of the stove may -lbeconveniently and easily lighted after the master burner has been started.

It will,` of course, be understood that the details `of the construction and arrangement of the parts of my push button lighter and the materials of which they are made may be varied according to circumstances.

It is my intention to cover by my claims any changes or modifications in the structure, arrangement and combination of the parts which may be reasonably included within the scope of such claims and within the scope of my invention.
