Figure 3 is a section on line 3 3 Figure 2.

Figure tis a section on line 4--4 Figure 1.

Figure 5 is a section on line 5 5 Figure 2.

Figure 6 is a vertical sectional view of a modified form of burner in accordance with this invention.

Figures 7 and 8 are vertical sectional l views of other modified forms.

Referring to the drawings in detail 1 denotes an annular open top base, provided with supporting legs 2,' detachably connected with the base 1 by set screws 3. The base 1 is formed with sockets 4 for the reception of the legs 2. The base 1 centrally of its bottom is formed with an opening 5 and with an upst-anding tapered. collar 6 having its inner face, at its lower end, forming a continuation of the wall of the opening 5. The opening 5 and collar 6 provide a clearance for the passage of a drive shaft 7, the latter being vertically disposed, and is operated from a motor 8, which is arranged below the base 1. It is to be understood that the base 1 can be supported in any suitable` manner other than that as shown.

Both forms of the burner, as illustrated, have as a part thereof,- an outer shell and an inner shell, referred to respectively and enerally by the reference characters 9 an 10. The shell 9 is cylindrical in contour, that is to say in vertical section, and the shell 10 flaring in contour, that is to say in vertical section. The shell 9 at its top is formed with a continuous inwardly extending annular flange 11 of arcuate contour. The shell 9 surrounds and is spaced from, a Haring sleeve 15 which at its upper end merges into the flange 11. The lower end of the sleeve 15 is provided with an inwardly extending upturned annular iange 16 which is curvilinear in cross section and forms a preheated lair deflector. The inner side of the sleeve 15. below and in proximity to its point of joinder with the iange 11, at dia-v metrically opposed points thereof, is formed with a ledge 17. The ledges 17 'provide a pair of seats for a purpose to be presently referred to. The fiange 11, at diametrically opposed points and at the top thereof, is formed with a vertically disposed, inverted U-shaped offset portion 18 having a squared edge 19. At the point of joinder of the sleeve 15 with the flange 1 1, at diametrically opposed points, openings 20 are formed. The offset portions 18 form continuations of the openings 20. The offset portions 18 are cut away to provide` seats 21. Mounted on the seats 21 is a closure strip 22 which is disposed diametrically with respect to the shell 9 and sleeve 1.5 and is arranged at the top of the shell 9.

Arranged within the sleeve 15, as well as being spaced therefrom, and of less height than the height of said sleeve, is a vertically disposed, hollow bell-shaped member 23 which is open at its top and at its bottom, and has its top formed with a pair of oppositely disposed channel-

shaped suspension arms

24, 25, which are mounted` on the` seats formed by the ridges 17. The

arms

24, 25, are closed by the strip 22, and the latter in connection with the arms 25 provide an air heating chamber 26 having an inlet for each end thereof provided by an opening 20. The outlet of the chamber 26 is formed by the open to of the member 23, and is indicated at 27. he diameter of the lower end of the member 23 is less than the diameter of the flange 16 and the lower end of the member 23 is spaced from said flange 16 and o poses the top edge of the latter. The mem er 23 forms a pre-heated air receiving chamber 28 which gradually increases in d1ameter from its inlet to its discharge end.

The shell 10 is interposed between the shell 9 and sleeve 15 and is arranged in spaced relation relative to said shell 9 and sleeve 15. lThe flare of the shell 10 is less than the flare of the sleeve 15. The shell l() is Iof greater height than the shell 9 and sleeve 15, but the top edge of the shell 10 is positioned below the upper end of the sleeve 15. The shell 10 depends a substantial distance below the lower end of the sleeve 15. i. The shell `10 is provided intermediate its ends with a right angularly dis osed,

annular flange 12, which forms a she f for an insulation body 13 and the latter is formed with an opening `14 through which extends the shell 9. The shelf 12 supports the shell 9. The shelf or flange 12 is provided with spaced inlet openin 29 ositioned between the shell 9 and t e she l 10, and said openings 29 are provided for suppl of air to an air receiving chamber 30 whic is formed by the shell 10 in connection with the shell 9. The openings-20 form outlets for the upper portionV of the chamber '30.

The shell 10 in connection with the sleeve 15,

i 4provides a pre-heating air chamber 31, which lili gradually increases in width from its upper to its lower end and at its upper end communicates with the upper portion of the chamber 30. The lower endof the shell 10 is provided with an inwardly extending, upturned flange 32, of curvilinear cross section, and which is of greater width than the flange 16 and the diameter of the flange 32 at its free edge is less than the diameter of the flange 16 at its free edge. The flange 32 iss aced` a substantial distance below, the

ange 16 and provides a combined oil trap and deflector. The shell 10 at its bottom 1s formed with a depending annular rib 33 and a pocket 34, and extended into the pocket 34, and surrounded by the rib 33 is the upper end of the base l. The trap formed by the which vflange 32 is arranged within the top of the base.

The bottom of the lbase 1 is formed with a discharge opening 35 for thev overflow of oil from the flange 32 or from any other source and adjacent said opening, the base 1 is furthermore formed with a vertically disosed semicircular flange 36 of materially ess hei ht than the height of the base and orms a retarder. Connected to the base 1, and surrounding and spaced from the flange 36 and of greater height than said flange, as well as extending over said flange 3 6 and secured to the side of the base 1, is a protector 37 provided with openings 38 for the passage of the oil overflowto the discharge opening 35, which communicates with an interiorly threaded nipple 39.

`With reference to Figures` 1 and 2, the

on the shoulder 42 and having said terminal f portion 40 extending therethrough is a circular disk 43 which provides an oil baille. Seated on thedisk 43, as well as of greater diameter than said disk, and further having said terminal portion 40 extend throu h the bottom thereof, is a cup-shaped impel er 44 1 having its inner face formed with radially disposed vanes 45, which gradually increase in width from their inner ends towards the upper edge of the impeller 44. The vanes 45 have their inner or'lower ends spaced a substantialdistance from the axis of the impeller 44.

Threadably engaging with the terminal l portion 40, is a hollow tapered oil distributing head 46, which is open at its upper end, as at 47, and provided near its base with a circumferentially extending series of spaced jet openings which are radially disposed with respect to the axis of the head. The pointed end 41, of the terminal ortion 40 extends into close proximity to t e opening 47. The impeller 44 has the upper portion thereof opposite tht` edge of the flange 16,but is spaced therefrom to form an inlet for the assage of pre-heated air from the chamer 31 for admixing with a mixture of oil and'airto be presently referred to. The admixing of the pre-heated air with the mixture of oil and air provides for satisfactory combustion during the operation of' the burner. The baille 43, impeller 44, and head 46 bodily rotate through the action of the drive sha 7. The top edge of the impeller 44 is positioned in alinement with the bottom tion 52 extends down Ythrough the chamber 28 and into the open upper end of the dis-A v ltributor head 46. A retaining means, indicated at 55 associates with the section 51 for maintaining it stationary, v

' The oil enters through the line 49 and is discharged into the head 46, where due to centrifugal force it is broken and distributed to the impeller 44. Ai'r enters through Vthe. inlets 29 and a portion thereof flows into chamber 26 where it is heated and the air also Hows into the 4chamber 31 where it l is heated. The heated air passes through chamber 26, into chamber 28, and then into the impeller, which acting upon the oil will facilitate the vaporizing thereof. The impeller 44, in vie-W of the vanes 45, sets up a slight vacuum in chamber 28. The mixed air and oil is discharged from the'impeller 44, at the edge thereof in connection with the edge of` the member 23 and mixes with.

the pre-heated air from the chamber 31 which passes between the Harige 16 and the v1in eller thereby facilitating combustion.

efenrin to Figure 6, the oil supply line.

is indicate generally by the reference character 56 and is arrange in the same manner as the air supply line 49, with this exception 'that the section 57 bf the line 56, which corresponds to the section 52 of the line 59.I is of less height than said section 52. The

i drive shaft shown in Figure 2 is of less height than the drive shaft shown in Figure 6, and the drive shaft shown in Figure 6 extends up into the chamber 28 formed by the member 23. The drive shaft shown inl seats-the head 60.

posed -jet openings 62 for the discharge of the oil therefrom. Mounted on the drive shaft is an impeller 62 having a centrall disposed horizontal rtion 63 against whic Ighe im ller 62 has its remaining portion extend ownwardl and outwardly, as indicated at 64 and sai porl neaaeae and fan 66 bodily revolve together on the operation of the drive shaft.

The distributing head, in both forms, provides for the oil to be carried in a thin ilm throughout the upper face of the imy ller and which assists in the va oriz'ing of `t e oil and when the re-heated air from the chamber 28 is supplled or conducted to the impeller, it admlxes with the thin film of oil yand facilitiates the vaporizing thereof,4 and owing to the manner of setting up a second air pre-heating chamber, so that such pre-heated air can be discharged or taken up by the mixture of oil and air, unusuallyT satisfactory combustion; is provided for.

The modified form shown in Figure 7 is similar in construction to the form shown in Figures 1 and 2, with this exception that the bell shaped chamber 23, openings 2O and 26 are dispensed with, and that the Haring .I

sleeve 69, which corresponds to the sleeve 15 is formed with a. single opening 70, of a diameter to snugly engage the section 51 of the oil su ply line 49. n

In the orm shown in Figures 7 and 8, the air pre-heating bell and assembly, as shown in connection with Figure 1, are dispensed with, and the sleeve 67 or 69, provides an uninterrupted mixing chamber.

Although, as shown, the flare of the shell `10 is less than the flare of the

sleeve

15, or 67 or 69, it is to be understood that the shell 10 can be perpendicular if desired.

The construction described,l provides a very satisfactory 'oil burnerof the rotary type and operates in a'manner to obtain a saving in fuel consumption, andl although -the preferred embodiments of the several structural elements of the device are as illustrated and described, yet it is to be understood that changes in the details of construction of such elements can be had, which will fall within the scope of the invention as claimed.
