UMTED STATES PATENT OFFICE.
THOMAS C. PURVES AND OSSIAN K. MITCHELL, OF LA GRANGE, ILLINOIS, ASSIGNORS TO JOY L. REICHELT, OF COOK COUNTY, ILLINOIS.
OIL-BURNER.
SPECIFICATION forming part of Letters Patent No. 642,716, dated February 6, 1900.
Application filed February 2, 1899. Serial No. 704,234. (No model.)
To all whom it may concern:
Be it known that we, THOMAS C. PUEvEs and OSSIAN K. MITCHELL, citizens of the United States, and residents of La Grange, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Oil-Burners, of which the following is a full, clear, and exact specification.
Our invention relates to individual heaters or burners for stoves, furnaces, &c., in which oil in its commercial liquid state is utilized as fuel.
The object of our invention is to concentrate a current of intensely-hot air upon and against a body of oil in such manner as to promote thorough combustion of the oil and its gaseous emanations without generating or permitting the escape of soot or carbon or permitting the precipitation or accumulation of sediment or foreign substances in the oil or oil channels or passages to interfere in any way with the flow of the oil. This We accomplish in the manner and by the means hereinafter fully described, and as particularly pointed out in the claims.
In the drawings, Figure 1 is a perspective View of our invention. Fig. 2 is a vertical central section of the same. Fig. 3 is a horizontal section of the burner, taken on a line corresponding with that numbered 3 3 of Fig. 2. Fig. 4: is a plan view of the under side of our invention. Fig. 5 is a view in elevation, illustrating the invention applied to a stove.
In the drawings, A represents a circular or other suitably-shaped base-plate which between its center and its outer edges is provided with two concentric walls I) c, that correspond in height, are separated from each other a suitable distance, and are located one within the other. Just outside the confines of the outside wall a base-plate A is provided with a series of circumferentially-elongated air inlet or supply openings (1 d, and tapped into and arising from its center is a suitably-shaped overflow-burner c, the upper end of which is preferably closed, except for a narrow slit or opening ftherein, and the lower open end of the bore of which has screwed into it the contiguous end of the oilsupply pipe B.
0 represents the cover of the heater and consists of a cylindrical-shaped shell the diameter of the sides of which is such that when placed upon the base-plate the lower edges thereof rest upon the latter concentric with and so as to inclose the series of air-supply openings d. These supporting edges of the cover are provided with a series of inwardlyprojecting lugs g g, that correspond in number to the number of openings d, are arranged at equal intervals apart, and project a distance corresponding to the difference between the radius of the outer surface of wall 0 of said base-plate and that of the inner surface of the cylindrical sides of the cover 0. These lugs are of a length corresponding to about half that of openings d, and their purpose besides that of centering the cover upon the base-plate is to permit of a limited regulation of air-supply through openings (1 simply by slightly turning the cover.
The side. of the cover opposite the baseplate is closed excepting a comparativelylarge central opening it therein, which forms the mouth of the combustion zone of the heater. The side edges 10 of this opening are flanged inward toward and at right angles to the baseplate to such an extent that their annular end edges project a suitable distance below the upper edges of the walls I) 0, but terminate on a horizontal plane above the upper end of the burner e.
About midway between annular flange 7c of the cover and the outer cylindrical sides of the same said cover is provided with a circular wall D, which depends downward from the upper closed side of said cover a distance corresponding to the height of walls I) and 0, about midway between which it is located.
Just between walls I) and c, and preferably nearer the latter, we tap into the upper side of the cover one leg of an inverted-U-shaped pipe E, which is of such proportions that the unconnected other vertical leg thereof depends in vertical alinement with the burner e a suitable distance down into the mouth of the opening h, substantially as shown.
Near the sides of the inclosure surrounded by the inner wall 1) of the base-plate we provide one or more drain-pipes G, the lower ends of which are tapped through said baseplate and extendvertically to and terminate at a point between the horizontal planes of the lower edges of flanges 713 and the top of the burner. These drain-pipes G prevent the accumulation of oil in the inclosure surrounding the burner from arising to such a height as to cut off the circulation of hot-air currents from the openings cl to the space in closed by flanges 7a.
The operation of our invention is as follows: The oil being turned on, it flows through pipe B and burner e and is suitably ignited. The base-plate and cover soon become heated and the fresh air is drawn in through the supply-openings d d and, pursuing an upward and downward course over walls I) and c of the base-plate and under wall D and flange 7a of the cover, becomes thoroughly heated before it comes in contact with the burning products of the oil in the central inclosu re of the heater. Owing to the fact that the oil extends to about the top of the drainpipes the passage to the central opening h is contracted, and as the air is heated and is moving upward as it passes between the walls D and b a portion of this inward rush of fresh air enters the pipe E and is projected downward from the superheated depending end of the same right into the center of the combustion. The hotter the burner becomes the better and more thorough the combustion of the oil, which latter, it will be observed, is comparatively cool until it enters the burner e.
The benefit derived during the operation of our invention from the depending pipe E when it is glowing hot is so great that its presence is considered necessary even if it were closed. up. We therefore desire to be considered as including it in our invention both as a solid or hollow element.
Pipe E maybe simply a denuded depending member of our invention. We prefer, however, to attach to the depending leg thereof a canopy or spreader K, so as to cause the flames as they issue from the mouth of the seat of combustion (the opening h) to flare outward and impart heat to a greater area.

The combination in a chambered heater provided with an overflow-oil burner, means for supplying oil to said heater, means for conducting air under atmospheric pressure through said heater wherebysaid air is heated, and a member depending into and discharging the air downwardly within the combus-.

2. The combination in a chambered heater provided with an overflow-oil burner, means for supplying oil to said heater, means for conducting air under atmospheric pressure through said heater whereby said air is heated, a member depending into and discharging part of the air from above downwardly into the combustion zone and means for supplying the residue of the air from below into the combustion zone.
