BURNER.

Specification of Letters Patent.

Patented Sept. .19, 1911.

Application filed March 3, 1911. Serial No. 612,133.

To all whom it may concern:

Be it known that I, VILLIS WV. CASE, S12, a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented. certain new and useful Improvements ilr Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertainsto make and use the same.

This invention relates to oil burners for general uses, and has for its purpose to pro vide a burner which will be more simple in construction, effective in action, and less expensive to manufacture than those heretofore proposed.

To these ends the invention consists in the novel details of construction and combinations of parts more fully disclosed hereinafter, and particularly pointed out in the claims.

Referring to the accompanying drawings forming a part of this specification in which like numerals designate like parts in all the views-Figure 1 is a side elevational view of a burner made in accordance with my invention; Fig. 2 is, a top plan View partly in section of the parts shown in Fig. 1; Fig. 3 is an end' elevational view of the parts shown in Fig. 1 with a slightly modified form of foraminous plate; Fig. 1 is a longitudinal sectional view of the burner; Fig. 5 is an end elevational view partly in sectionof the burner but looking in a direction opposite to that from which the parts shown in. Fig. 3 are seen; Fig. 6 is an enlarged detail View partly in section of the air re tarding plates taken on the line 66 of Fig. 4 showing an arrangement of perforations slightly differing from that disclosed in Fig. 3; Fig. 7 is an enlarged detail sectional view of a form of the plates slightly differing from that shown in Fig. 2 and removed from the burner; and Figs. 8, 9 and 10 are detail views of still further modified forms of air retarding plates.

1 represents any suitable body portion, but preferably of metal,which is provided with an enlarged air passage 2, and an oil passage 3. Passing through the bottom of the oil passage 3 is a hollow sleeve 4 provided with an oval V-shaped port 5 for the admission of oil into the passage 6 of the sleeve 4, and '1' represents a blunt pointed rod fitting the sleeve 4, as illustrated, and surrounded by the stufling box 8 in order to prevent leakage of oil. The extreme end 9 of the rod 7 traverses the passage (3 beneath the V-shaped opening 5, and as will be clear' from Fig. 2 of the drawings, enables a very fine regulation of the amount of oil adinittcd to the passage 6. Any suihiblc means 1.0 may be provided for turning the rod 7 upon its screw threads 11, and thereby adjusting the end 9 of. said rod relatively-to the opening 5, as will be readily understood.

The air passage 2 is connected with the delivery 13 of the burner, through the fo-.

rainmous retarding plates

14 and 15 preferably provided with the registering

openings

16, 17 and 18 as shown. 'llheseplates may be readily rotated relatively, to each other, so as to partially or entirely close the said openings 16 and 17 when desired, as will be more fully described below, and thereby regulate the quantity as well as the pressure of the air delivered through the mouth 13 of the burner. The extreme end of the sleeve or tube 4 is preferably provided with a series of radially projecting fingers 20, as best shown in Fig. 2, and these fingers are located substantially in the center of the larger openings 18 of the retarding

plates

14 and 15, for a purpose more fully disclosed hereinafter.

Suitably mounted in the casing 1 is a rod such as 21 having an eccentric finger 22, which engages a slot 23 in one of the plates such as 15, so that when said rod 21 is rotated on its longitudinal axis, the said finger 22 will cause the plate 15 to turn upon an axis passing through its center and the tube 4, and thereby partially or entirely cause its perforations 16 and 17 to move out of register with the corresponding perforations in its companion plate 14. In order that the rod 21 may be turned just far enough to make the registering passages 16 and 17 of the desired size, it isprovided at its end opposite the linger 22 with an index 25,

passing over a suitable scale 26 which conindex 25 in place. The said plate 27 may be also conveniently provided with a turned up stop 81 to hunt the extreme movement of f the index finger 25.

wliereupon it enters the passage 6 of the sleeve or pipe at through the J-shaped opening controlled by the extreme end 9 of the rod 7, and it finds its way to the radiallyextending fingers 20 of the said pipe i, and owing to its surface'tension it tends to stick to said fingers. Air may be admitted from any-suitable source through the passage 2, whereupon it blows through the central tapered opening 18 of the retarding plates between. the said fingers 20, and' across the end of said passage (Sand thereupon finely divides or atomizes the oil delivered from the said pipe 4. This finely divided air and oil forms a cone which leaves the burner through its mouth 13 and may be ignited inside the furnace or other place at which it may be desired for use. The amount of oil in the conemay be regulated to a nicety by simply adjusting the extreme end 9 of the rod 7 relatively to the V-shaped opening 5, and by this means the amount of heat delivered by theignited cone is likewise adjusted to any desired degree.

In order that a more perfect. combustion may be attained, and also in order that the cone may be'ignited at a point very closeto the inouth 13, the index 25 is so turnedas to admit air through the registering orifices l6 and 17 of the retarding plates 1-1 and 15.

Since the air under pressure in passing through these cone tapered orifices 16 and. 17 is greatly reduced in its velocity, it may enter the cone as almost still air, and thereupon admix With the oil and air entering through the orifices 18 almost to the mouth of the burner, which of course will cause the flame to extend up very close to said mouth, as above stated, while at the same time furnishing suflicicnt oxygen to insure a very ellicient combustion. Of course by turning the'indcx 95 further so as to admit more air through the orifices 16 and 17, the cone becomes longcr, and also by changing the position of the extreme end 9 of the rod 7, the said cone may be caused to deliver a greater or less (piantity of heat. Further,.by changing the degree of the registration of the openings 16- and 17, the oxidizing or reducing portion of the flame may be brought to any desired point of the material being heat-- ed. This feature, among others, rcndcrsmy burner exceedingly useful for metallurgical operations.

I find from actual tests that an exceedingly ellicier'; metallurgical burner can be produced by the means abovedisclosed when air at only about four ounces pressure is admitted into the passage 2. I have furtherfound that by simply converging the orifices 16 and 17 as illustratcd in Fig. 7, the cone. can be made to converge at any particular point in the furnace, and thereby an intense heat may be delivered wherever desired. After converging, of course, said cone then diverges as it traverses the furnace.

In the modification shown in Fig. 8, a single sheet 35 of foraminous material is disclosed. I find for certain purposes that such a sheet, or even wire cloth, may be used instead of the retarding

plates

14 and 15.

In the further modifications disclosed in Figs. 9 and 10, I have illustrated retarding disks 36 and 37 provided with radial openings 38 adapted to be placed into registering or non-registering position and by a means similar to that disclosed in connection with the retarding disks let and 15. I have found for certain purposes that these disks 36 and '3; give excellent results. In all cases. however, it will be observed that I may use a gravity feed for the oil and that a simple fan blower producing a. pressure I as low as from four to six ounces or less gives most excellent results.

It is obvious that those skilled in the art may vary the details of construction and the arrangement of parts without departing from the spirit of my invention, and there fore I do not wish to be limited to sue features except as may be required by the claims."
