A. R. ANTHONY BURNER Filed Nov. l2, 1920 Patented Apr. 10, 1923.

ALFRED R. ANTHONY, OF DETROIT, 'MICHIGAN.

BURNER.

Application led November 12, 1920. Serial No. 423,707.

To all whom t 'may concern:

Ee it known that l, Lrnnn l. ANTHONY, a citizen of the United States, and residing at Detroit, Wayne County, l ate of Michigan, have invented certain new and useful Improvements in Burners, of which the following is a specification.

The present invention relates to oil burners. The principal object of the present invention is to provide an improved construction at the front end of the burner for thoroughlyv atomining the fuel and mixing it with the air and at the same time obtain a relatively short flame. 'Fo these ends the fuel tube is provided at its front end with a plurality of series of holes spaced along the length thereof adapted to discharge air t0 intersect the jet of fuel. rFliese holes may be inclined so as to give the air a whirling motion to thereby restrict the length of the flame obtained with the burner.

Another feature of novelty resides in the structure of t-he tip of what may be termed the air tube. This tip is provided with a circular series of holes at its front end so that air is discharged into the stream of mixture issuing from the end of the fuel tube. Preferably the holes in this tip are inclined both to the axis of the burner and circumferentially so that the air is given a whirling motion as it issues from these holes.

Other objects and features of novelty will be apparent from the description taken in connection with the drawings in which,

Fig. 1 is a longitudinal sectional view through al burner having the present invention incorporated therein;

Fig. 2 is a sectional elevation taken substantially on the line 2 2 of Figure 1;

Fig. 3 is a sectional elevation taken substantially on the line 8 3 of Figure 1;

Fig. 4l is a sectional elevation taken substantially on the line 4-4 of Figure 1; and

Fig. 5 is a sectional elevation through the tip of the air tube taken substantially on the line 5-5 of Figure 1.

Referring to the drawings the numeral 10 designates the hollow body of the burner having its opposite ends open and formed at one side with a main air inlet 11 and at another side with a by-pass air inlet 12, as described in my application ySerial No. 245,930 filed July 20, 1918. A fuel tube 13 is provided and has an enlargement 1li, at

one end thereof, this enlargement vbeing threaded into the opening 15 at one end of the body 10 thereby closing said opening. An air tube 16 is disposed around the fuel tube 13 being threaded on the enlargement 14 and being spaced from the fuel tube 13 to form the air passage 17, the air tube 16 near its inner end having apertures which open into an annular chamber 19 communieating with the by-pass air inlet 12, which latter is adapted to continuously supply air to the passage 17 surrounding the fuel tube The air tube 16 is spaced from the walls of the burner body to provide a second air passage 2O communicating with the main air inlet 1l and separated from the by-pass air inlet 12 by the partition 21 formed in the burner body. The inner end of the fuel tube or pipe 13 is provided with a suitably threaded aperture 22 for connection to a fuel supply. The fuel tube may be in two parts. the forward end being in the from of a cap 23. r-rs shown this cap is threaded on a reduced section 24C of the tube. rlhe wall of the. cap is provided with a plurality of series of holes through which air from the passage 17 is discharged to intersect the jet of fuel issuing from the aperture 25 at the end of the reduced portion 24 of the fuel tube.

ln the form of the invention illustrated, three series of holes are formed in the wall of the cap. @ne series of holes 26 is located just in front of the fuel aperture 25. As clearly shown in Figure 2 of the drawings, the holes 26 are inclined to the radial so that the air issuing from the same is given a whirling motion in the chamber 27 of the cap. Furthermore from an inspection of Figure 1 it will be seen that the holes 26' are inclined to the axis of the tube so that the air is discharged with a forward component of velocity as well as tangentially or whirling. i second series of holes 28 is disposed a slight distance in advance of the series 26. Preferably the bore of the cap is slightly enlarged as at 29 in order to accommodate the greater volume of mixture. lt will be noted that the holes 28 are inclined both to the axis of the cap and circumferentially. Preferably in order to get a better atomization and a shorter flame, the circumferential inclination of the holes 28 is opposite to that of the holes 26. In other words, the air discharged from holes 28 is given a whirling motion in an opposite direction to that issuing from the holes 26, ln the forni of the invention shown there is another series of holes through the Wall of the cap, these holes being indicated at 30. Like the other holes they are inclined both to the axis of the cap and circumferentially and discharge into a chamber 31 which is of larger diameter than the charnbcr 29.

A cap 32 is adjustably mounted on the air tube 16 and has a conical end Wall 33, the inner surface 34 of which is parallel and adapted to contact with the conical tip 35 of the cap 23. In a similar' manner the body of the burner has a cap 36 provided with an inner conical surface 37 which may contact with the outer conical surface 38 of the cap 32. The end Wall of the 'cap 32 is provided vwith a series of holes 39 which are inclined both to the axis of the burner and circumfercntially, so that the air discharged tl'icrefrom is given a uf'hirling motion in accordance With the circumferential inclination of said holes.

1n the operation of the burner the jet of fuel issuing from the aperture 25 is intersected by the whirling air discharged through the holes 26. This whirling air, of course, atomizes the jet and reduces its forward velocity. Then the mixture is intersected by the whirling air from the next series of holes, that is, the holes 23, and as this air is preferably whirling in the opposite direction, the forward velocity of the mixture is again retarded. A similar action results from the holes 30. It will be observed that the chambers 26, 29 and 31 increase in diameter, this being desirable in order to accommodate the quantities of air discharged through the holes in the cap. As the mixture leaves the cap 23 it is further broken up by the air issuing from the holes 39 in the cap 32. lf desired, the holes 39 may be disposed so as to Whirl the air in the opposite direction from that of the holes 30 which results in a further slowing up of the forward velocity of the mixture. Of course these alternate whirlings of the air tend to shorten the flame from the burner and at the same time give a very efficient and thorough mixing of the fuel and air. The plurality of series of holes disposed so that the air is fed successively, breaks up the oil much finer and mixes it better with the air than if a single series of holes were employed. rEhe air issuing from the holes 39 -further mixes the air and fuel and the final regulation as to the length of the flame may be obtained by discharging a conical stream of air from between the caps 32 and 36. ln designing the burner t .e number of series of holes in the cap on the fuel tube will be determined in accordance with the pressure of the air, If the burner is to be used with high pressure, a less number of series of holes is required than When a lower pressure is employed.
