BURNER FOR GAS 0R OIL.

Specification of Letters Patent.

Patented Jan. 6, 1920.

Application filed March 12, 1918. Serial No. 222,022.

To all whom it may concern:

Be it known that I, HERBERT FORESTER, a subject of Great Britain, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and use ful Improvements in Burners for Gas or Uil, of which the following is a specification.

This invention relates to burners for stoves, furnaces, and the like, and has for its principal object to provide an eflicient burner, which is adapted for using either gas or oil as fuel, so that when the gas pressure is low, oil may be used instead of the gas in the same burner.

F or a clear understanding of the invention, reference will be had-to the accompanying drawings, which simply are intended to illustrate the same, and the invention will be hereinafter fully described and the novel features thereof particularly pointed out in the appended claims.

In the drawings corresponding parts are designated by similar characters of reference.

Figure 1 is a longitudinal sectional view of a burner constructed in accordance with my invention,

Fig. 2 is a plan view, with a part in section to better show the construction,

Fig. 3 is a front end view, and

Fig. 4 is a cross section taken on line 4--l of Fig. 1.

Referring to the drawings, 1 represents an elongated cylindrical casing, which termi nates in a round or other shaped head 2. The upper wall of the casing, near its open or inlet end 3, is provided with a longitudinal slot 1, and the head with suitable slots 5. Above the casing 1 and over its slot 4 is arranged an elongated cylindrical gas gen erating chamber 6, which has a closed rear end 7. The gas generating chamber 6 and the casing'l pass through and are supported in openings in a pair of plates 8 and 9. EX- tending from within the casing, near its rear end, and along the underside thereof, is a tube 10, which is constructed of comparatively thin material for becoming quickly heated. The rear or inner end 11 of said tube curves upwardly and is open, while the forward end 12 curves downwardly and is closed by a removable cap 13 for permitting the insertion of a wire or the like for easily cleaning the tube. The forward downwardly curved end 12 of the tube 10 is provided with a nozzle 1% directly opposite the open or inlet end of the casing. The forward end of the gas generating chamber 6 is closed by a plug 15, in which is threaded a feed pipe 16 leading from an elevated supply reservoir of kerosene or other liquid fuel. A. shut-off valve 17 is arranged in the feed pipe 16 for controlling the flow of theliquid fuel to the gas generating chamber. For obtaining a steady and even flow or distribution of the liquid fuel as it enters and passes through the gas generating chamber 6, a core of suitable absorbent material, such as asbestos, is arranged therein as indicated by 18. When using ordinary gas, the longitudinal slot 4 of the casing 1 is closed, to shut off the flame from the gas generating chamber 6, by means of a slide 23, which is rotatably mounted within the casing. Said slide is provided with a longitudinal opening 24, which is adapted to register with the slot 4c, when the slide is rotated in one direction, and not register with it when rotated in the other direction. For convenience in operating the slide 23, the same is provided with a laterally extending handle 25, and this handle slid in a recess 26 cut in the end of the casing, the shoulders 27 of which serve as stops for limiting the movement of thtz1 handle and therefore the rotation of the sli e.

In order to obtain complete and satisfactory combustion by using ordinary gas with the above described oil burner, it has been found in practice that, the gas valve, indicated by 19, must be arranged with its noz- 21c 20 on an angle, with relation to the cylindrical casing l, for directing the flow of gas across the open or inlet end 3 of the casing and against the inner side thereof. The purpose of directing the ordinary gas on an angle into the casing, is to obtain the proper mixture, which is not the result when said gas is induced straight into the casing, as there is too great a proportion of air due to the necessarily larger air inlet opening for oil burning. The valve 19 is fixed to a gas supply pipe 21, and is provided with shut-off means 22.

Operation: One or more burners are arranged in a stove, heating furnace, or other placesin the usual manner, with the feed pipe 16 connected to a supply reservoir of liquid fuel, such as kerosene or other of the heavier oils, which reservoir is placed at a suitable elevationso that the liquid fuel will flow to the burner by gravity, and the pipe 21 is connected to the ordinary gas supply pipe. 7 The slide 23 is rotated to bring its longitudinal opening 24; in registration with the slot 4 of the casing, and the gas turned on at 22. A light is applied to the gas escaping at the slots 4 and 5. The shut-off valve 17 is opened to admit the oil to the gas generating chamber 6, and as soon as said chamber becomes sufficiently heated, the oil is generated into gas and escapes at the nozzle 14. The gas valve 19 is now shut off and the gas generated from oil'continues to burn. VVhe'n it is desired to use only the ordinary gas, from the nozzle 20, the valve 17 is closed and the slide :23 rotated to close the slot 4 of the casing. In case there is no gas, the generating chamber 6 may be heated by a torch to start the burner.

From the above, it is seen that either ordinary gas or oil may be used as fuel With this burner, and it is to be especially noted that the directing of the ordinary'gas across the open end of and against the inner side of the casing 1 is essential to the accomplishment of the best results in a burner adapted for both oil and gas.

chamber, the tube having a nozzle opposite said opening of the casing, and a valve arranged laterally of said nozzle for-directing ordinary gas at an angle across the opening of the casing and against the inner side thereof, substantially as described. v

2. In burner, the combination of a casing, the casing having a perforated Wall and an opening, a gas generating chamber, means for feeding oil to thegas generating chamber, a tube leading from the gas generating chamber, the tube having a nozzle opposite said opening of the casing, means for supplying ordinary gas to the casing through said opening, the casing having a slot opposite said gas generating chamber, a slide rotatably mounted in the casing, the slide having a longitudinal opening adapted to register with the slot of the easing, a handle extending from the slide, and the casing having a recess for the handle whereby the movement of the slide will be limited, substantially as described.

In testimony whereof I aflix my signature.

HERBERT FORESTER.
