3 Claims. (Cl. 158-56) My invention relates to an oil burner, and has to receive water, and suitably connected to the for its principal objects, to generally improve lower portion of the bowl and communicating upon and simplify the construction of the existwith channel 4 is a pipe 5 that leads from a ing forms of oil burners, and particularly, those suitable source of water supply. li desired, this 5 burners utilized for household heating purposes water supply pipe may be taken into the bowl 5 and also in smudge pots, further, to provide an through the side thereof.
oil burner that is relatively simple in construc- When the burner is installed for use, it is tion, composed of few parts, all of which are positioned just above the bottom 'I of a stove, readily accessible for the purpose of inspection, furnace, Smudge pOt T the like, and the air replacements and the cleaning of the interior of Supply pipe s and Water Supply pipe eXtehd 10 the burner, and further, to provide an oil burner thIOugh Seid bottom. that develops very little, if any, smoke and soot Formed on the upper Sillfdee 0f the hOttOm 0f while in operation. the bowl I between the channel 4 and the open Further objects of my invention are, to provide upper end 0f the air supply pipe 8, is a vertically an oi1 burner of the character referred to, with disposed Shoulder l0, and the surface of Said 15 improved means for supplying air to support shoulder and the adjacent surface of the bottom combustion of the liquid hydrocarbon utilized as 0f the bowl are made smooth by machining, or fuel in the burner, and also to provide means Otherwise. for continuously delivering water to the burner, The burner prOpeI Whieh iS pOStOhed within which water is converted into vapor that mixes the howl J'uSt ehOVe the Opeh lipper ehd 0f dil 2O with the air and vaporized liquid hydrocarbon, inlet pipe 8, comprises a shallow bowl 3, and to bring about perfect combustion and consequent fOlmed integral with the under Side 0f Said bewl high eiciency of the burner in the development and depending therefrom iS e well I l, the lower of heat. end of which rests directly on topof the bottom With the foregoing and other objects in view 0f hOwl l, and against the Shoulder Ill. All 2 5 my invention consists in certain novel features surfaces Of the howl 3 and the well II are prefof construction and arrangements of parts that elehly machined, ih Orde!1 t0 prOVlde Smooth Surwill be hereinafter more fully described and faces that may be easily Cleehed and which claimed and illustrated in the accompanying Counter-eet tehdehey 0f dllSt, SOOt dhd the like,

ment of the invention, I designates a bowl that FOFIhed thleligh the Well iS e plurality 0f may be formed of cast or pressed metal, and apertures l2, Whieh permitS all' IOm the uppel formed through the upright wall of said bowl end 0f Supply pipe 3 t0 diSChaige into bowl I are breather apertures la through which air dl'eetly e'eulld the hOdy 0f the burner 3.
40 may freely circulate. Removably positioned on Formed thTOllgh the lOWel pOl'tiOil 0f the uptop of the bowl is a ring-shaped baiile plate 2 Tight Well 0f the hufhel hOWl 3 iS e plurality which is for the purpose of directing heated air ei Smell apertures I3, which permits the hydrothat rises along the inner surface of the bowl carbon in either liquid Ol VepOIiZed COrlditiOh toward the center thereof, thus to a certain to discharge from the lower portion of the burner extent concentrating the heat that is developed bOwl. 45 by the burner. Formed in the center ofthe bottom of the Communicating with the bottom of the chamburner bowl 3 is an opening I4, and surrounding ber within the bowl I, is an air supply pipe 8, same is an upwardly projecting wall I5. Formed and to control or throttle the ow of air through through the lower prtion of this wall I5 is a this pipe, the same is equipped with suitable plurality of apertures I6, which permits hydro- 50 valvular means, for instance, a manually operable carbon in either liquid or vaporous condition to damper such as 9. discharge from the burner bowl. A liquid hydro- Forrned in the upper surface of the bottom carbon supply pipe 6 is connected to the burner of the bowl I, and surrounding the upper end of bowl 3, and removably positioned on top of the the air inlet pipe 8 is a shallow channel 4 adapted burner bowl and resting on top of the wall I5 55 that surrounds the central opening I4, is a cover plate I1.
In the operation of my improved oil burner, a small amount of liquid hydro-carbon is permitted to ow into the burner bowl 3 through supply pipe 6, and as this liquid hydro-carbon discharges from the apertures I3 and I6 it is ignited, land the resultant heat quickly heats the burner to such a degree as to vaporize the liquid hydro-carbon as it continues to flow into the burner.
The vaporized liquid hydro-carbon discharges through the apertures I3 and I6 and burns within the bowl I, and the air to support combustion passes upwardly through supply pipe 8 and thence through openings I2 in wall Il to mix and burn with the liquid hydro-carbon vapor.
The ow of air to the burner may be accurately regulated by proper manipulation of the valvular means or damper within pipe 8, and
the ow of liquid hydro-carbon to the burner may be controlled by suitable valvular means (not shown) that is associated with supply pipe ii.
While the burner is in operation, a certain amount of water is permitted to flow from supply pipe 5 into channel 4, and the heat from the4 burner converts this water into steam which unites with the air and liquid hydro-carbon vapor in producing a highly inammable mixture, the burning of which produces a relatively high degree of heat. The addition of air and steam to the vaporized liquid hydro-carbon, insures perfect combustion of the latter, and the moisture or steam content added to the mixture is highly effective in counter-acting the development of smoke and soot during operation of the burner.
An important feature of my invention is the air supply pipe 8 that supplies air to the burner within the bowl, for by extending this air supply pipe 8 downwardly a substantial distance, for instance, down to within an inch or two of the floor on which the heating appliance rests, said appliance functions as a circulation heater, that is, the air that is heated by the heater is caused to circulate through the room in which the heater is located. During such circulation the heated air rises from the heater and the cooler air is taken from a point adjacent the oor and delivered into the bowl.
Thus it will be seen that I have provided an oil burner that is relatively simple in construction, inexpensive of manufacture and very effective in performing the functions for which it is intended.
The burner comprises relatively few parts that are easily assembled or taken apart, and the construction of the burner proper and the bowl in which said burner is positioned is such, that said burner and bowl may be very easily and quickly cleaned and maintained in condition to function to the greatest advantage.
While my improved burner is particularly designed for use in household heaters, stoves and furnaces, and also for use in smudge pots, the burner may be advantageously and economically employed wherever heat that is devoid of smoke and soot is required.
It will be understood that minor changes in the size, form, and construction of the various parts of my improved o'il burner may be made and substituted for those herein shown and described without departing from the spirit of the invention, the scope of which is set forth in the appended claims.
I claim as my invention:
