GEORGE W. ERRIA, OF LAKE'CHARLES, LUISIAN.;

FLUIlD-FUEL BURNER.

Linares.

Specification of Letters Patent. Patented elulya', lgl.;

Application filed .September 21, 1914. Serial No. 862,802.

r suchas are adapted for burning kerosene or other heavy hydrocarbon fuel oils.

An object in -view is the production of a burner applicable to the Firebox. of an ordinary range or other like fire box, the parts being disposed to be readily accessible.

A further object is facilitating, by a simple means, the action of flaming gas in the heating of the retort portion of the oil supply pipe for insuring effective gasification prior to discharge of the fuel toward thel point of consumption.

With this and other objects in view, the invention comprises a base adapted for application to a fire-box, and a supply, pipe cxtending across the base to form a retort and "sustained on the base and having a discharge pipe communicating with the retort and extending along the base, air mixing casings upstanding from and communicating through the base and inclosing the discharge part being seen in elevation and parts being broken away, Fig. 2 is a transverse vertical section taken on the' plane indicated by line 2 2 of Fig. 1 and looking in a direction indicated by the arrow.

Y Referring to the drawing by numerals, l indicates a base 'which is adapted to, be applied in the fire box of the range or other like fire box, the walls of which are indicated at' 2, and the intervening space between the Walls and the base l is filled with asbestos or other fire proof substance 3 adapted to prevent the entrance of air from beneath the base into the space above the base except through the mixers hereinafter mentioned.

rests.

Upstanding from and preferably formed integral with base l and spaced apart longitudinally thereof are tubular Ifrusto-conical air mixers 4-4s A fuel supply pipe 5 extends longitudinally of the base l and through suitable openings in the Vmixers il,"

the'pipe at its inner end beingi bent upwardly and then extended forwardly to forni a retort portion 6 which at its outer.. en d connects with a proper supply pipe ladapted to deliver the fluid fuel. The retort por-v tion 6 extends in a line directly vabove 'pipe 5, as clearly .seen in Fig. 2, yand immediately above each of the mixers 4,',pipe 6 carries a deliector plate 7. Each plate 7 is preferably formed with a ring orA band 8 surrounding the pipe 6 Aand detachably .secured in place thereon as b v set screw 9 threaded through the ring and engaging the pipe. Bracket 10 is fixed to base 1,-at one side thereof, and extends upwardly and is bent laterally to engage retort 6 for supporting the same, the upperA end portion of the bracket being bifurcated for receiving the pipe and in which. bifurcationthe retort 6 rllie outer end of pipe 5 is provided with a cap l1 adapted to engage 'the cuter mixer 4. when the pipe is at its innermost position, the pipe being shiiitable longitudinally, vas indicated by the dotted line position in Fig. l'so that the discharge apertures l2 formed in pipe 5 and normally diso's'ed' a roximatel central 'of mixers Il may be moved to a position outside of said mixers for enabling the discharge of fuel onto the base l. lt is to be noted that the shiftable pipe 5 fits snugly in the lateral openings of the mixer casings and constitutes closures for said openings so as to prevent the ingress of air therethrough. in the use of the device, lthereby insuring that the proper combustion will take place upon passage of air vertically through said casings. l

This is a very essential. feature of inydevice. y Base l is formed with depressions or iire pans 13 for receiving such fuel, the pans being adapted to be supplied with fuel for enabling starting of the burner. The apertures l2 direct their discharge upwardly normally against the baille plates 7, and in starting the burner the retort 6 and pipe 5 are drawn outwardly to the dotted line position when the fuel supply is turned on. As soon as the pans 13 are substantially filled the supply is cut o' and the pipes are shifted back to their inner position andthe the surrounding fire box.

fuel in the pan 13 is lighted and allowed toA burn up for heating the pipes 5 and 6.-

Thereupon the fuelv supply is again turnedl on and the gas created' by the heat of the pipes discharges through apertures l2 and it is ignited. iiaiiies 7 deflect the iiame and cause it to spread so as to substantially ll The jet from each aperture l2 acts as an injector for drawing in air through the receptive mixer lso that the combustible mixture is delivered from each of the mixers 4 continuously during operation. When it is desired to reduce the intensity o'l the heat the fuel supply is cut down and the'air; supply may be proportionately out down by closing the doors of the range and preventing vthe intake of the air beneath the base l, or the doors or slides may be only partially closed, the adjustment of the parts being proportionate to the quantity of air required, a greater amount of air being admitted beneath the base l as the amount of fuel supplied is increased.

Having thus described the invention, what l. claim as new is The combination with an inelosure, of a fuel burner disposed therein 'and comprising starting panand having a' discharge opening adapted in operation todirect the dis-y charge throughl the casing7 ythe supply pipe snugly fitting in said casing apertures and constitutinga closure therefor 'whereby to prevent passage of air through said openings.
