Specification of Letters Patent.

Patented Sept. 16, 1919.

Application filed August 11, 1919. Serial No. 316,680.

To aZZ whom it may concern Be it known that I, CHARLES C. SHEPARD- son, 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 Kerosene-Burner, of which the following is a specification.

This invention relates to burners especially designed for burning kerosene or coal oil, one of its objects being to entirely eliminate carbon deposits which have heretofore seriously interfered with the use of this grade of oil as a fuel, such elimination being effected by the use of a preheater, a vaporizer and a superhcater, the generated gas issuing from the nozzle of the burner in a clean and dry condition so that, when mixed with air, it will produce an intense flame.

. Another object is to so construct the burner that it will stand up indefinitely and without being injured by the heat generated.

A further object is to provide simple and eflicient means for spreading the flame from the burner,

1 With the foregoing and other objects in view which will appear as the description proceeds the invention consists of certain novel details of construction and combinations of parts which will be hereinafter more fully described and pointed out in. the claims, it being understood that various changes may be made in the construction and arrangement of parts without departing from the spirit or sacrificing any of the advantages of the invention as set forth in the appended claims.

Tn the accompanying drawings the preferred form of the invention has been shown.

Tn said drawings Figure 1 is a vertical longitudinal section through the burner.

Fig. 2 is a section on line 22, Fig. 1. Fig. 8 is a section on line 33, Fig. 1. a Fig. 4c is a plan view of one end portion of the burner.

Fig. 5 is a section through the nozzle of the burner.

Referring to the figures by characters of reference 1 designates a pan adapted to hold gasoline or other fuel used in initially vaporizing the fuel in the burner and this pan maybe provided with transverse reinforcmg ribs 2 at intermediate points while formed in each end wall of the pan at the upper edge thereof is a recess 3. A drip cup 4 is provided on one end of the pan 1 and opens through a drain opening 5 into the pan.

The burner includes'a header 6 constituting a vaporizer and provided with a boss 7. Fitted tightly on this boss is one end of the burner tube 8 the other end of which is closed by a boss 9 projecting from a head 10. Another boss 11 projects outwardly from the head 10 while projecting from the inner boss 9 is a tube 12 tapered for the greater portion of its length and ter1ninating in a short cylindrical portion the end of which is approximately at the center of the tube 8. The inner end of the bore in this tube 12 is cylindrical while the remainder of the bore is tapered slightly and merges into a flared opening 13 within the head 10 and boss 11.

7 A longitudinal series of outlet slits 1 1 are formed in the bottom of the tube 8, these slitsbeing segmental as shown in Fig. 3 and formed in the opposite side portions of the tube 8 are additional longitudinal series of slits 15' and 15.

Secured at its ends within the head 10 and the header 6 is a preheating tube 16 located close to the bottom of the tube 8 and directly under the middle portions of the slits 13. j A fuel supply pipe 17 having a valve 18 opens into one end of the tube 16 while the other end of this tube opens into the header 6 close to the bottom thereof.

Deflectors 19 and 20- connect the header 6 to the head 10 and arelocated at opposite portions of and in contact with or close to the tube 8. These deflectors extend across the lower portions of the slits 15 and 15 and serve to hold the several parts of the burner together securely. The deflector 19 can be a solid rod, as shown or can be a tube closed at one end. The deflector 20 is atube opening into the header 6 and constituting a superheater. An elbow 21 is connected to one. end of this superheater and opens into a nozzle 22 having inner and outer seats 23 and 24 converging to an orifice 25 in the nozzle. A needle valve is mounted in the nozzle, as shown at 26 and is adapted to be seated against the seat 23 to control the flow of fuel. A stem 27 projects from the end of the valve and loosely throughthe orifice 25 and has a spreading nipple 28 at its free end. By opening the valve the nipple is drawn toward the outer seat or flare 2 1 and serves to spread the fuel as it issues from the nozzle so that it will enter the flared end 13 close tothe-'walhthereof and create a strong suction of air into the tube 12 and a thorough mixing of the air andgas.

After a fire has been started in the pan 1 coal oil is directed into the preheating tube 16 and passes thence into the vaporizer or header 6. From here it flows through the superheating tube 20 to the nozzle 22 from which it is discharged into the tube'1 2 with air mixed therewith. The gas is ignited at the slits 14.15 and 15. The flames issuing from the bottom of the tube 8 willbe split into two sheets extending to opposite sides of the tube 16 and will spread laterally and upwardly" under the deflecting means '19 and 20 and thence around the tube 8 and upwa'rdly. Along the sides of thepan' 1 are provided deflecting lips or flanges 29 which serve to prevent heat from going" downwardly from theburner. By arranging the preheating tube 16 between the two sheets of flame issuing from the tube S'said tube 16 is heated without unduly chilling the flame and will preheat the fuel admitted to the said tube 16. The flames spreading from the tube 16 will heat the header 6 to 'a red heat and in this header the pre heated fuel will be thoroughly vaporized and will spread over the extensive heated surfaces wherebyall carbon will be burned and choking ofthe apparatus thus be pre-' vented. From this vaporizing header the fuel will flowinto' the superheating tube 20 and be raised toa very high temperature and thoroughly dried, in which condition it is mixed with the air and burned. By making all-of the parts of the burnerof steel they will contract and expand uniformly and the device will stand up under use for an indefinite period. The particular means for preheating, vaporizing and superheating the fuel prevents the burner from becoming clogged with carbon and the same can be used for a very long time without the necessity of cleaning it. Attention is called to the fact that the flames issuing from the lower openings 14 are not chilled by the tube 16 and that the greater portion of the flames issuing from the orifices 15' and 15 are above the deflectors and are not, there fore, materially chilled by said deflectors. Accordingly the fuel will give an intense blue flame and as the tube 16-and the deflectors do not receive the full heat of the flames they will not be injured thereby, but will merely be heated to a red heat.

The lower portion of the head 10 is concentric with the tube 8 and rests on the sides of the cup 4:. As the notches 3 are slightly wider than the diameter of the tube 1(), it thus becomes possible to rotate the burner relative to the pan 1 to cause the flames to flow at any desired angle to the horizontal. This is particularly desirable where the burner is used in a fire box having a water coil and it is desired to adjust the burner angularly to throw the flame onto the coil.

A coal oil burner including a burner tube having side and bottom series of orifices, an air tube extending into said burner tube from one end, a preheating tube under and close to the burner tube and extending across the centers of the orifices in the bottom of said tube, a header at one end of the burner tube and communicating with the preheating tube, said header constituting a vaporizer, spreaders extending along the sides of the burner tube and across the lower portions of the side orifices, one of said deflectors constituting a superheating tube, and a nozzle connected to the superheating tubeand opening into the air tube.
