LIQUID-FUEL BURNER.

To allwhomz't innig/concern: l..

Bek it-known thatI, HERBERT FoREsTER, ay subject of Great Britain,y residing at` Cleve- 4 land, yin the county of Cuyahoga and State;l

to the burner by gravity so as to produce al blue flame'without the need of air pressure.

Another object of the invention is toprovide a burner, ofsaidicharacter of simple and inexpensive construction, which is easy to clean without detaching it from the furnace or other places `where. installed.

In order that the invention may berclearlyy understood, the lsame will be hereinaftery fully described as illustrated in the accompanying drawings, showing a preferred embodiment thereof, and itsv novel features will be distinctly pointed out in the appended claims.

Figure 1 is a longitudinal section of a burner constructedvin accordance with my invention,

F ig.2 yisa frontl end view i of the same,

Fig. 3 is a sectional view taken on line 33lof Fig. 1, and" Y Fig. 4 is a plan view of the elongated semi-cylindrical chamber.

Referring to the drawings, 1 represents an elongated semicylindrical casing having its flat side 2 forming the top.y Said top is preferably constructed of pottery and is perforated by two rows of suitable transverse slots 3, separated by a wall 4. The open ends of said casing are closed by a pair of plates 5 and 6, which are held in place by tie-bolts 7 passing longitudinally through the casing. The front end plate 6 is provided with an opening 8, in which is fixed a tubular neck 9 for admitting air `and gas to said casing. Above the casing 1 and directly over the wall 4: of the top thereof, is arranged an elongated cylindrical gas generating chamberlO, which has a closed rear end l1 and a threaded open end 12. This gas generating chamber passes through and is supported in openings in the plates 5 and specmeauon of Letters Patent. i

its lower side is provided with a recess 13 fork receiving the upwardly curved end 14 of a tube l5, Vwhichfis constructed ofy comparatively think material for becoming yquickly heated. Said end ofthe tube is open and extends to the top of the gas generating chamber yl0. The' tube'l extends along the underside of said gas generating chamber, and -its forwardv end 16 passes through an openmgin the front plate 6. Said forward Thenozzle 17 isprovided with a flared or conicaloutlet 18.y A removable cap-screw 19 is .threaded into the forward end of the -tube 15 forclosing the same, and also to pron y 19.1918. .v f

- end of the tube 15 curves downwardly and is 'i `provided with a rearwardly extending nozzle 17 directly opposite the ltubular neck 9.

to the front end plate 6 by bolts-22. The

cap 2Ov is provided with a central aperture 23, andxis threaded in alinement therewith at 24. for the attachment of a feed pipe 25 v leading from an elevated supply reservoir of kerosene or other similar liquid fuel.- A shut-off valve 26 is arranged in the feed pipe for controlling they flow of the liouidffuelto the'casing 10. `For obtaining a steady `and even llow or distribution of the liquid fuel as it enters and passes throughv the casing 10, a core of suitable absorbent material such as asbestos is arranged therein as indicated by 27.

In operation, one or more burners are arranged in a heating furnace, under a boiler, or other similar place in the usual manner, and the feed pipe connected to a supply reservoir of liquid fuel such as kerosene or other of the heavier oils. The supply reservoir is placed at a suitable distance above the burners, so that the liquid fuel will flow thereto by gravity. As the fuel enters the gas generating chamber 10, the core of absorbent material 27 arranged therein becomes saturated for its entire length. In order to light the burner, a torch or other heat giving means is applied for heating the gas generating chamber 10 sufficiently to transform the liquid fuel held by the core of asbestos into gas. The gas thus generated passes through the tube 15 and escapes at the nozzle 17 with great force. As the gas leaves the nozzle, it spreads outwardly in all directions due to the conical outlet' i8,

and becomes mixed with air before entering the tubular neck 9 and passing into the casing l. The flow of the mixture, on account of the conical outlet of the nozzle, strikes the Wall of the neck 9 as indicated by the dotted lines, `thereby producing compression action similar to an injector. Upon escaping` throughithe slots 3 in the top of the casing,`

the mixture becomes ignited by the torch. After being lighted, the'aine keeps. the gas generating chamber heated, and the burner continues to operate. The flame also heats the outer Wall ofthe tube 15 and thereby causes the gas passing therethrough to becoine super-heated for obtaining greater expansion of the gas, and consequently higher velocity of the flouY thereof. This produces perfect combustion and a' blue'fianie Without the need of air pressure,

A burner constructed as illustrated and described, Will operate efhciently for using kerosene or other similar oils as fuel Without the need of air pressure, thereby saving the expense of air pressure or lforced draft; completey combustion-is obtained, thus it is economical in the use of fuel; and on account of its .simple construction, it is inexpensiveY to manufacture and easy to keep insane-e and above the top of said casing, and the tube having an outlet opposite said opening of the casing, substantially as'described.`
