OIL-BURNER.

SPECIFICATION forming part of Letters Patent No. 721,900, dated March 3, 190s.

Application inea August 5, 1902.

To LZZ/ whom t may concern:

Be it known that we,VALDEMAR F. LssoE, of the city, county, and State of New York, and LUTHER D. LovEKIN, of Ardmore, Montgomery county, State of Pennsylvania, have invented an Improvement in Oil-Burners, of which the following is a specification.

Our invention has reference to oil-burners; and it consists of certain improvements,which are fully set forth in the following specification and shown in the accompanying drawings, which form a part thereof.

The object of our invention is to provide a simple and durable construction of burner which has capacity for spraying the oil to be burned by forcing it through a nozzle in a thin sheet or film and subdividing it by a series of transversely-acting currents of air under pressure, preferably in diagonal directions, so as to produce a spiral or gyrating motion to the particles of oil and air beyond the end of the burner, where the subdivided oil is burned.

The burner herein described is especially adapted for use in the system of burning oil as fuel set out in our application, Serial No. 117,673,filed July 30,1902,a reference to which application Will show the manner of supplying the burner with oil and spraying air under pressure, as well as the additional air at lower pressure, for combustion purposes, said application clearly illustrating the manner in which we have commercially applied our invention.

In carrying out our invention forming the subject-matter of the present application we employ an air-tube having its rear end provided with an air-inlet and its forward end wi th a spraying-bushing having a central aperture for receiving the oil-nozzle and a series of surrounding spraying-apertures through which the air is forced under pressure, said apertures being preferably arranged on an incline or spiral, so as to impart a spiral or gyratory motion to the air and oil, and with said airtube awe combine a central oil-tube having its rear end furnished with a connection for oil and its forward end with a nozzle tting the bushing and a regulating and spraying rod ad j ustably secured in the oil-tube for reg- Serial No. 113.468. (No model.)

nlating the character of oil film or spray delivered from the nozzle.

Our invention also comprehends details of construction which, together with the above features, will be better understood by reference to the drawings, in which- Figure- 1 is a longitudinal sectional elevation of an oil-burner embodying our improvements. Fig. 2 is a cross-sectional elevation of same on line o: of Fig. 1. Fig. 3 is a crosssection of same on line y y of Fig. 1. Fig. Il is a sectional elevation of the forward end of a modified form of ourburner, and Fig. 5 is an elevation of one part of the spraying-bushing.

2 is the air-tube of the burner, through Whichair is forced, preferably, at about one and one-half pounds pressure. The air is supplied to the tube by an inlet 3 and is discharged at the forward end through apertures 6 in a bushing 11, screwed into the end of the tube. This bushing is preferably hollowed out or recessed on the front or outside face, as at 5, and into this the apertures 6 open, said apertures being arranged on spiral inclines, as more fully indicated in Fig. 3, and grouped about a central aperture 7 ,which is tapered and adapted to receive the end of the oil-nozzle 9. These apertures are directed inward and open through the recessed face of the bushing. The oil-nozzle 9 is conical, has a tapered hole, and is of such length that its nose just protrudes through the bushing. It is fitted on the interior with a star-frame 10, which is clamped in position upon a shoulder by the oil-pipe 8 when screwed into the nozzle. The rear end of the oil-pipe is secured to an L-head, into which the oil is fed under about fifteen pounds pressure by a pipe 12.

Extending through the head l1 and the pipe 8 ,isa control-rod 13, the end of which is tapered to form a throttling-valve with the nozzle to regulate the extent of orifice for the escape of oil. The end of the rod beyond the nozzle is enlarged, so as to form an annular head 14, against which the oil impinges and by which it is spread or sprayed outward in a thin layer, as indicated by the arrow in Fig. 4. By adjusting the rod 13 the extent and angle of the spraying of the oil may be varied. The rod 13 is made adjustable by having its rear end screw-threaded, as at 16, and working in the head l1. The extreme rear end of the rod passes through a stuffingbox l5 on the head and is provided with a hand-wheel 17, by which to rotate it for adjustment purposes.

Vhen the oil is forced out under about fifteen pounds pressure,it is spread and brought to a condition of a very thin film. This is rapidly dissipated into a fine spray by the action of the series of spiral air-jets from the apertures 6, which not only produce the subdivision, but also gives to the mixture of air and oil a gyratory motion, which is important in that it produces the better subdivision, a most intimate admixture with the combustion-air supplied to the furnace from around the burner, and a constantly-shifting name, which secures uniform distribution of the heat within the furnace.

In use the burnerts into the usual furnace or fire-box, the ange 18 on the burner-tube acting as a support and means for securing it in place upon the projecting front of the furnace.

To cheapen the cost of constructing the bushing 4, we may make it in two parts, as shown in Figs. 4 and 5. In this case the part 4b has the grooves 6b cast in it, as shown in Fig. 5, the construction resembling Very closely a bevel-gear.having spiral teeth 4c. The bushing 4 is screwed into the end of the tube 2 and is made with a conical aperture adapted to receive the conical surface 4:c produced by the teeth of the part 4l. This latter part has also a conical aperture 7, adapted to receive the nozzle 9. When the part 4b is placed upon the end of the nozzle and the bushing 4u screwed into place, it clamps the part 4b firmly upon the nozzle, and the grooves (3b constitute a series of spiially-arranged apertures. In this case, as in the construction shown in Fig. 1, the bushing is formed with the recessed end, as at 5. While we prefer that these apertures shall be diagonal or spirally arranged, this is not essential.

While we prefer the construction shown, the details may be modified without departing from the spirit of the invention.

Having now described our invention, what we claim as new, and desire to secure by Letters Patent, is-

l. In an oil-burner, the combination of an air-tube, a head at its front end havinga series of perforations arranged about its center and directed inward, an oil-nozzle extending through the center of the head and constituting a valve-seat, an oil-pipe leading to the nozzle and having no communication with the air-tube, and an adjustable controllingrod extending through the nozzle and having its end annularly grooved to form a valve for the nozzle and a head out of line of the discharge of the air for directing the oil outward in a thin film into an isolated position so as to be met by the air-jets from the head and transformed into a spray.
