Application mea June` 111, isaafseriai No. 544,612.`

To all whom t may concern: Y

Be it known thatIrJosnrH R. NICH0L SON, a citizen' of the United States, residing at Wichita, in the county of Sedgwick'and use in stoves and furnaces, and one object is to provide a. lourner consisting of but few parts, which are inexpensive to manufao ture and can he readily installed in the firepot of a stove or furnace for domestic purposes.

A further object is to provide a burner which is safe and economical in the use o-f liquid fuel, and wherein eiiicient combustion is had, to the end that excessive soot and obnoxious odors are eliminated.

Other objects will hereinafter appear, and in o-rder that the invention may be fully understood, reference will now =be had to the accompanying drawing, in which:

Fig. y1 is a vertical section of the lou-rner on line I-I of Fig. 2.

Fig. 2 is a plan view of the |burner with its lair duct removed. n

Fig. 3 is a detail side eleva-tion of the air duct forming a portion of the burner.

Fig. 4 is an inverted plan view of the air duct. y

In carrying lout the invention a plate 1 is i employed, having an upwardly-extending marginal ange 2 and a centrally-disposed, saucer-like depression 3.

4 designates a feed pipe leading from an oil tank, not shown, to the lower central portion of the depression 3 in the vplate 1. The usual valves for controlling the flow Iof oil through the pipe 4 vmay be employed, but as they form no part of the present invention it has not 'been deemed necessary to disclose them in the drawing.

5 designates an overflow pipe leading from the upper portion of the depression 3 and through which the fuel oil is carried away from the burner `in the event that the flame should become accidentally extinguished and thus fail to consume the oil delivered through the feed pipe 4. Any

well-known safety device may he used in connection with .the overflow pipe 5'for automatically cutting ofi' the supply of oil` deliveredito the feed pipe 4 and `thus avoid" danger of explosion fromthe overflow of oil.

6 designates a flat wick of mineral wool,l asbestos or other suitable material whichis placed in the central lportion ofthe depression 3 and overthe delivery end of the feed pipe 4. Y

7 designa-tes an air pipe through which air is supplied Ito the flame to efciently sup' port combnstion. Said air pipe is of .substantially inverted U-form and consists of two ventical legs 8 and a transverse leg 9 f responding shoulders 12 on the legs 8 snugly fit, so that air cannot pass 'between the seats 11 'and said shoulders 12 and interfere with the operation of the llourner. The lower central part of the transverse leg 9 of the air pipe 7 has a discharge nozzle 13 Yfor directing air downwardly upon the flame.k

In practice, the plate .1 may loel circular as shown or rectangular to fit within the -fire box of a stove or the fire pot of a fur- TheJ plate 1 is installed on a level nace. with the grate and the space loetween the flange 2 and lthe side walls of the fire box or pot is hermetically sealed, so that all air reaching the llame at the' burner must pass through the air pipe 7. In startin the burner, oil is admitted through the feed pipe 4 to the wick 6 on the plate 1. After the wick 6 becomes saturated'it is ignited with a match, or the like, and the llame thus produced spreads around the air pipe 7 and thus heats the air passing upwardly therethrough from the lash pit. The heated air is discharged downwardly from the nozzle 13 directly upon the flame with which it thoroughly oo-mmingles, 'so that a blue flame,

denoting perfect combustion, is had. The

intense heat produced by the flame eliminates excessive 'soot and efficiently consumes yall of the o-il delivered to the hurner and thereby overcomes the obnoxious `odors which arise from unburned oil. As the -heated air discharged from the nozzle 13 is From the foregoing deseripision it is aipparent that I have produced a fbumer em-y bodying the advantages above pointed out; and While I have `shown and described the preferred Jform of the invention). I reserve the right to make such y@manges 1n the construction, combinatio-n and `arrainLgferiien of parte as properly fall Withn the spirit and scope of the elainr Having thus described my invention, Awhat I claim and desire Ito secure by Letters Patent, Ais 1 An oil @burner consisting of a, plate having im 4upWardiy-turned marginal Hangevand a shallow `cenral depression, meansor con;- duetirrg liquid fri-elta said depression, a suitable Wick arranged yin the depression7 an overow pipe leadino' from the pla-te, and an inverted Umhaped an duet consisting of two lege extending dim-gh and belwsaid plate, tapered shoulders on seid legs whichl fit Within corresponding seats in thfepla'e,4

and a transverse leg Connecting the upper portions of the first-mentioned legs and having-a1y downturned disch-arge nozzle arranged in axial alinement with the axis of Said ehaillow depressiom e In `testimony whereof I eix my signature, in the presence of two witnesses.
