To all whom it may con/cern.Y

Be it known that I, JOHN C. Zinc-nina, residingl at Seymour, in the county o'l Baylor and State of '.lexas, have invented a new and improved Crude-Oil Burner, of which the following is a specilication.

My invention relates to improvements in that type of burners or stoves especially designed for burning crude oil in its natural unrelined state as i'uel; and it primarily has for its object to provide an improved construction et' crude-oilburning means of the general character stated of a simple, economical, and etlective nature in which the oil is perfectly and under an economical feed positively consumed without producing smoke or odor.

.ln its `generic nature my invention comprehends an improved type oi' crude-oil burner devices adapted tor use with the common type oi' heating-stoves that use coal or wood 'For fuel without materially changing their general arrangement, and the said burner devices are designed for etlecting' a quick conversion ot' the oil into a vaporous fuel,V

whereby the maximum iuel products of the oil is obtained and the residuum or non-convertible elements oi the oil is collected., so that the same may be readily removed.

lin its more complete form my invention includes, in combination with a stove having a vertical heating drum or chamber, a conically-shaped air-funnel supported within the heating-drum and whose upper or wide end forms aclosure means for the upper part oli the heating-chamber oi' the drum and whose lower or contraetedend leads the oil under a strong' blast against the burner devices beneath it and which acts as a means for thoroughly heating the air as it is iied against the burner and also as a iiame-spreader and in such manner that none but heated air is 'fed to the burner.

My invention also embodies a special construction ot' burner having its parts so designed that the oil fed down through the funnel under gravity or forced feed is delivered under great Vforce against an upper or target member of the burner, whereby to spray the lighter particles so they instantly become converted into gas and are consumed, while the heavier particles descend over the lower part of the target member and are Afurther converted into gas and consumed as the heavy non-convertible substance passes down onto the separating-cone member and into the pan.

My invention also provides such a type of gaseous-oil burner which acts on the crude oil in such manner that the lighter or l'loatable solids that detach themselves during' the process et' converting the oil into gas will be drawn up into the `flue as the heavier solids attach to the upper perforated cone, from whence they may be removed after extinguishing the lire.

ln its more subordinate Jt'eatures my invention consists in certain details of construction and peculiar combination o'l` parts, all oi' which will behereina'lteriully described,pointed out in the appended claims, and illustrated in the accompanying drawings, in which Figure 1 is a perspective view of a crudeoil-burning stove constructed in accordance with my invention, portions being broken away to clearly illustrate the general arrangement ol" the internal parts. Fig'. 2 is a vertical section of the same, taken practically on the line 2. E2 of Fig. l. Fig. 3 is a horizontal section taken on the line 3 3 on Fig. 2. Fig. 4 is a view which illustrates the perforated target-cone and the separating-eone member of the burner detached, and Fig. 5 is a perspective view ot' the collecting-pan detached.

l'n the accompanying` drawings .l have illustrated the burner, the pan, and the combined air-funnel and radiator and oil-leading member as adapted for and combined with the ordinary type olt coal or wood heating-stove having a sheet-iron drum mounted on the combustion-chamber or lire-box; but l desire it understood that the said parts oi" my invention without materially changing may be readily adapted for other types oi heaters. The type of heater shown l. have found as permitting the most economical and el'lective application of my invention.

The base A of the stove is oi cast metal, suitably mounted on the legs c a, and having an inverted tapering' tire-pot c', closed tight at its bottom, whose upper end has an annular ornamental rim a, provided with an annu lar seat fr, to receive the bottom of the sheetiron drum b, and the said upper end oi the pot u, has the annular hot-air-blast chamber a", Vlied through a valved opening or slide-damper a5 in the door side of the drum in the usual manner, as best shown in Fig. 3, which also shows the slots a in the chamber a" that lead the blast in streams or iets radially over the burner.

The drum 7; in my arrangement of oil-burner is closed by the ornamental annular cast rim c, having a pendent flange c, that slips down inside the top of the drum, and the said rim o has an opening nearly thefull diameter of the ,l viding the funnel fZ, as shown, the fresh air rim, in which is pendently held a cone-shaped funnel (Z, whose upper or large end has an ann ularflange CZ' to rest on the rim c, as shown.

The lower or small end of the'funnel c terminates in a short restricted straight nozzle (Z2, that extends in a plane slightly below the y annular air ring or chamber on the top of the lire-pot and to a point in practice about three inches above the upper or target member of the burner devices, the reason for which will be presently explained.

6 designates the oil-feed pipe that connects with the storage-tank or other source of supply and which joins with a valve 6, with which the pendent or discharge pipe 6" connects and vwhich extends down into the funnel Z to a point about midway its length and ends with an ejector-nozzle ZG.

The burner device proper comprises, essentially, but three partsthe pan 7, of a size to freely lit on the bottom of the lire-pot and slightly dished to convey the flow therein to the center, a hollow conical casting 8, havingl its edge terminating' in pendent flange 8b, notched, as at 8C, that detachably seats in the pan and has a central upwardly-projecting stem 8, and asecond cone-shaped member 9, of much less diameter than that of the casting 8 and which has a vertical hub having a socket 9u in its under side to rest on the stem 8 and to hold the target-cone elevated above the casting 8. The target-cone 9 has a series of apertures 9b, and said target forms the spraying-cone, as it is directly against the upper face that the mixed air and oil is forced under pressure from the funnel (Z.

The manner in which my invention operates and the advantages of the same are best explained as follows: To start the fire, saturated waste is placed under the target-cone 9 and ignited to effect the preliminary heating of the burner members 8 and 9. As soon as the target-cone is heated a small quantity of oil is allowed to drop onto the target, which is increased until the target is at the maximum incandescence. The damper of in the annular hot-air chamber (f is opened or closed as the flow of oil is increased or diminished--z'- e., when the flow of oil is slight and no smoke is produced during its combustion if the damper a" is closed then the said damper Z5 is allowed to remain closed, but should the flow of oil be too great to be fully burned with only the air fed in through the funnel Z smoke will be produced, and to prevent this smoke production the damper of is opened just sufficient to feed in the additional amount of air required to fully consume the oil without production of smoke. The draft down the funnel (Z and up the chimney-flue (and in through the damper U7 and up the chimneyflue when the damper is open) will be sufliciently strong to prevent the escape of combustible gases from the stove, and by profed in therethrough will be concentrated directly on the target-cone. Since in connection with the flue the intense heat in the lire-pot creates a powerful draft down the funnel and heats the funnel, it follows that the air-blast drawn through the contracted end of the funnel creates astrong suction on the discharge or ejector end of the oil-pipe, and thus materially aids in keeping up a proper feed of the oil and also in preventing the clogging of the nozzle of the pipe, which might occur under ordinary gravity-feed of the oil therefrom. The oil and air mixing in the lower or contracted end of the funnel becomes at once thoroughly heated and converted into a gaseous fluid which discharges under great force against the target portion 9EL of' the target-cone 9, and such impact of the mixed air and vaporous fluid serves to thoroughly pray the lighter particles of the fluid, and thus cause them to instantly ignite as they are thus diused, thereby creating, as it were, a maximum spreading of the flame, which under the force of the whirling air-current. caused bythe influx of air into the closed fire-pot from the funnel, as also from the annular air-space on the fire-pot, and the passing of the up-current through the perforations in the target-cone, creates a heat intense enough to at once convert and consume all but the incombustible particles of the oil and create a powerful heat within the drum, which as it radiates externally of the drum also keeps the funnel to such heat that will thoroughly heat the incoming air before it intermixes with the gas, a great desideratum in this type of heaters. By providing the funnel member Z and making it of cone shape, with the larger diameter at the open or top end in communication with the atmosphere and the smaller diameter adjacent the target-cone, the heat from the internal surface of the funnel passes off into the room, thereby greatly increasing the heating capacity of this type of stove. As the heavier convertible particles of the oil pass over the lower edge of the perforated face of the target-cone 9 they become consumed, thus effecting a positive consumption of all the convertible parts of the oil without smoke or odor, and the non-convertible parts, such as asphaltum and the like, drop olf the targetcone 9 onto the lower cone 8, which for convenience of description I shall term the separatingcone. The non-convertible parts which fall on the separating-cone S-flow off the same and down underneath such cone through the apertures 8c into the collectingpan 7. As the non-convertible parts of the oil are subjected to a powerful heat in a restricted space they become baked, baking in the pan 7, from which they can be readily separated when the said parts are cooled by simply removing the several parts through the stove-door and cleaning them with any suitable instrument.
