vThe present invention relates to improvements/in burner. atomizers, and hasfor anwiththe result vthat the life of furnaces 'and that of boiler tubes is prolonged.

A further object of the inventionV4 is to provide an improved burner in which the l parts are standardized, individually replaceable, and easily assembled or readily removed for cleaning when desired, requiringk no skilled operator for this purpose.

With the foregoing and otherobjects in 20 view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto.

In the drawings, wherein like symbols re- `out the several views,

Figurevl is a longitudinal sectional view taken through an improved burner structure 'accordinglfto the present invention, fj 3G Figure 2 is a section taken on the line 2-2'in Figure 1,

Figure 3 is an endview of the supporting casting with parts broken away,and parts shown in section, -v kF'gure 4 is anA interior en'd'view of the atomizer box or container,l

Figure 5 is aV section takenvonthe line 5-'5 in Figure 4 showing the ball member andatomizer disc inoperative position,

Figure 6 is a planviewof the atomizer disk, and f Figure ,7-7 inFigure 6.l A v ReferringY more particularly to'fth'e drawings,4 10 designates the guidef pipe and y111 the burner, pipe which is locatedwithinthe guide pipe and is of smaller diameter. lThe *improved atomizer is Vcarried within .the pipe 11, uponthe outer screw threaded-end fer to like or corresponding parts through- 7 is a section taken on'fthe line.

I! of whichjis removably fitted anut112 having a peripheral enlargement sufcient to extend I out to and engage the inner wall of the guide .pipe 10, which is inwardly of the free end thereof; whereby a support is given to the burner pipe 11 at the end about the atomizer nozzle. The nut 12 is further peculiarly i formed in .that it carries an inwardly directed flange 13 which is spaced forwardly from the end of the burner pipe 11 when the nut 12 is screwed home onthe pipe. *In the space between the flange 13 and adjacent end of the pipe 11,'are iitted the flange 14 vof the atomizer box or container 15, and the rperipheral edge of the'atomizer disk 16.

The box 15 is open at the flanged end 14, and the disk 16 abuts against this open end and closes it save for the burner orificel? which Visfprovide'din the central portion of the disk 16, which 'centralportion is provided with the external boss or enlargement 18' disposed opposite the vcentral'internal-.cavity 19 with which the tangential grooves .2Ov communicate. These grooves 20 are made in the inner face of the' disk 16, and they communicate at tangents with the semi-spherical jcavity19. `VAs'shown in'r dotted lines in Figyure V5, the base walls of the grooves 20 slope J or become deeper toward the cavity 19.

TheboX or container 15 extends inwardly offthepipell 'and is shown as concentric l 4with the nut '12K Therinner end' 21 ofthe container is provided I withnumerous pery forations disposed in' one Vor more circumferouter row22. The central .portion vof Ithe end head 21 is blank and Vformed on its internal face with partially spherical cavity '24.

Confined within the 'container`15 is a ball 25 vof larger diameter thany the diameter Vof the cavity 19. 'lhi'svballseats between the cavity in the Vdisc-and the cavity-24 and tion between the discharge end of -the'tanlge'ntial'k groovesl and the burner orifice 17.
