WILLIAM NEWTON BEST, or Los ANGELES, CALIFORNIA, ASSIGNOR TO JOHN H. BEST AND EZRABEST, or QUINCY, ILLINOIS.
Specification of Letters Patent.
Patented June 11, 1907.
Application filed March 26, 1903. Serial Nli- 149,687-
To all whom it may concern: I
Be it known that I, WILLIAM NEWTON BEST, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Air-Carbureting Oil-Burner, of which the following is a s ecification.
, This invention is base on the principle of operation set forth in my application Serial No. 148851, filed February 17, 1903, whereby the natural draft of an ordinary stove or furnace is enabled to eflect the mixture or carbureting of air with a more of less volatile oil, such as petroleum distillate. In my said application the air was drawn through or Within the body of oil to be taken up, whereas my present invention contemplates the exposure of the oil to the draft of air by lateral contact or otherwise as hereinafter set forth.
The mainobject of my present invention is to enable the oil to be taken up by the draft of air without necessitating the passage of air interiorly of the oil carrying means.
A further object of the invention is to provide an oil burner for volatile or semi-volatile oils, of superior efficiency and extreme simplicity, and which will carburet the air prior to combustion in distinction to burning the oil directly.
The accompanying drawings illustrate the invention.
Figure I is a vertical transverse section on the line II in Fig. II of a bumer embodying my invention. Fig. II is a side view of said burner. Fig. III is a plan of the burner with the cover or deflector removed. Fig. IV is a longitudinal section on the line IVIV in Fig. I. Fig. V is a diagrammatic section of art of a stove or fire-pot with my burner in pIace therein.
Referring to Figs. I to IV, the burner comprises a base 1 with an upwardly extending formed a trough, channel or elongated opentop ed receptacle 3 for the oil. A duct 4 lea s downwardly from the channel to connect with the oil supply pipe 5.
A lateral extension 6 of base 1 on one side of the standard or support 2, is slotted or perforated as shown at 7 to ermit upward passage of air. Extending o liquely downward from the upper part of rib 2 to this lateral extension 6 is an inclined burner plate 8 that is perforated at 9 to permit passage of air and has lips or flanges 10, 11 that form receptacles or catch-basins for the oil that runs over the rim of the main receptacle in startmg.
A cover plate or deflector 12 is adapted to extend over the burner. One edge of this cover rests against a flange 13 on the outer edge of base 1, and the other edge of the cover extends over the receptacle 3, nearly to the outer lip thereof. This cover plate extends completely over the opening of the receptacle and so close thereto as to form, in conjunction with said receptacle, an elongated slot-like passage or outlet slot wherein the current of air is confined against the surface of the oil in the receptacle. The space between the inclined burner plate 8 and the base extension 6 forms a chamber which communicates with the outer air through openings 7, and also communicates through the openings 9 with a draft conduit or chamber between the inclined biu'ner plate 8 and the cover plate 12. This cover plate 12 rests, by pins 14 projecting from its under side, on the inclined burner plate 8, and lateral flanges 15 of said cover extend down on each side to overlap walls 16 extending from the base-extension 6, so that the said baseextension, the inclined burner plate 8, the side walls 16 and flanges 15 form a passage or conduit by which the air is directed later ally over the oil in receptacle 3. This receptacle or channel 3 at the point where the duct 4 enters same has a boss or raised floor 18, to prevent deposits in said channel from being pushed or jammed into said duct when the channel is cleaned or scraped, and an upward projection 19 of the outer lip or rim of receptacle 3 is provided opposite this duct 4, so as to compensate for this rise in the bottom of the trough or channel.
The burner above described is intended to be used in an ordinary stove, being placed in the firepot 20 of said stove as indicated in Fig. V so as to act as a closure therefor and force all the natural draft to pass through the openings 7, 9, in the base-extension 6 and inclined burner plate 8, and the current of air so passing is deflected by the cover plate 12, so as to pass over the'oil in the channel, and by contact, suctional effect and the disturbing influence of friction due to its motion, to take up oil from said receptacle and become carbureted.
In starting, the oil is turned on till it overflows and runs down to the supplementary lips 10, 11 and is there ignited. The heat generated will soon warm the parts of the burner specially, the cover plate 12, and will also create a natural draft, which will cause suction of air as above stated over the oil in receptacle 3. The inclined burner plate 8 and cover 12 converge as they approach the receptacle 3 so that the air is accelerated as it reaches the receptacle and by reason of its high velocity, together with the suctional effect, it takes up oil from the receptacle forming a carbureted mixture that burns with a blue or smokeless and intensely hot flame.
The cover plate 12 may be removed when it is desired to inspect or clean the burner.
It will be observed that the flow of air is lateral or transverse to the oil receptacle, the air passing up inside and over the receptacle. In the case of my prior application above referred to, there is also a lateral flow of the air over the receptacle, but the air passes interiorly of the oil receptacle, whereas in the present case the flow of air is exterior of the oil receptacle.
W hat I claim and desire to secure by Letters-Patent of the United States is 1. An air carbureting burner comprising a base, a rib on said base having a trough forming its top and provided with a duct leading to said trough, an oil supply means for said duct, said base having a lateral extension and a wall at each side of saidextension, an inclined cover plate resting on said extension and on said walls and extending over the trough in proximity thereto to form an elongated slot, and an inclined burner plate extending from the upper part of the rib to the base extension, forming a chamber between said incline and the base, said inclined burner plate and base being provided with perforations communicating with said chamber, and the incline having a flange above the perforations therein.
2. An air carbureting burner comprising a base and a rib thereon having a trough formed at its, top and provided with a duct leading to said trough, an oil supply means for said duct, said base having a perforated lateral extension provided with a flange at its outer edge and with a wall at each side of said extension, an inclined burner plate extending from the rib to the base extension and a cover plate resting on said flange of the base exten sion, and provided with pins resting on said burner plate, said cover plate extending over the aforesaid trough and forming an elongated outlet slot and conveying upwardly toward said burner plate and forming a convergihg air supply chamber leading to said outlet s 0t.

5. An air carbureting burner comprising a perforated base having an oil supply duct leading upwardly therethrough at one end and a flange at the other end, the side of the supply duct toward the flange being inclined and pro vided with oil receptacles, and an inclined cover, one edge of which rests against the flange and the other edge is provided with legs which rest against said inclined side and hold the cover at a distance therefrom to form an inclined flue with an outlet adjacent to said supply duct, there being a wall at each end of said base to form a chamber there above.
6. An air carbureting burner comprising a perforated base having an oil supply duct eading upwardly therethrough at one end and a flange at the other end, the top of the supply duct being provided with a trough and the side of the supply duct toward the flange being perforated and provided with oil receptacles above said perforation, and an inclined cover, one edge of which rests against the flange and the other edge is rovided with legs which rest against said inclined side and hold the cover at a distance therefrom to form an inclined flue with anoutlet adjacent to said supply duct, there being a wall at each end of said base to form a chamber there above.
In testimony whereof, I have signed my name to this specification. in the presence of two subscribing witnesses, at Los Angeles, in the county of Los Angeles and State of California, this 20th day of March, 1903.
