cally any furnace and which when installed provides for the generation of a high degree of heat while being economical in the consumption of fuel.

A further object of the invention is to provide an oil burner having these advantages and capacities and which is reliable and safe in operation and easy and comparatively inexpensive to manufacture.

Other objects and advantages reside in certain novel features of the construction, arrangement and combination of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanying drawings forming part of this specification and in which Figure l is a perspective view showing one embodiment of the invention.

Figure 2 shows the burner in diametrical vertical section, parts being shown in elevation for the sake of illustration.

Figure 3 is a view in section on line 33 of Figure 2.

Figure 4 is similar View on line 4.-4 of Figure 2.

Figure 5 is a detailed perspective view of the combined air deflector and flame spreader.

Referring to the drawings, the numeral 1 designates generally a burner constructed in accordance with the present invention. The burner comprises a substantially cylindrical bowl 2 having an outwardly and upwardly flaring flange 3 at its upper end and having an inwardly directed annular bottom plate 4: at its lower end. Intermediate its ends the bowl 2 is provided with an annular supporting ledge 5 which rests on the upper end of a flanged supporting ring 6 carried by a plurality of legs 7.

1927. Serial No. 188,457.

The burner is placed in the fire box and may be held in position by a filling of sand which is placed in the fire box up to the level of the top of the bowl. The bowl 2 also has integrally formed therewith an inner vertical wall 8 which connects with the bottom wall at in spaced relation to the body of the bowl and which terminates at its upper end in the plane of the inner periphery of the flange 3. i This wall 8 defines an annular space providing an oil chamber and a wick receiving space.

Oil is supplied to the lower end of this i chamber by means of an oilsupply' pipe 10 which leads from an automatic control box llto which oil issupplied from any suitable reservoir. The oil which flows into the space 9 rises under a wick support designatedv generally at 12 and consisting of a flat annular plate 13 and supporting lugsl l, the plate 18 fitting loosely in chamber 9 and permitting theoil to flow freely around the same. A wick is positioned in the space 9 on the wick support 12 and it consists of eight-ply asbestos cloth which can be burned from either side and which is incased inblack iron bands 16. The upper end of the wick terminates justabove the upper end of the wall 8. 1 Means is provided for supplying air to the burner in such manner as to generate a high degree of heat yet make for economy in the consumption of fuel. This means includes an air supply pipe 20 which leads from a blower 21 and which has one end flanged over the margin of an openingin the annular bottom wall 4: as indicatedat 22 in Figure 2. Acornbined air deflector and flame spreader designated generally at 23 isprovided and comprises a conical body 25 terminating in an outwardly extending lip 26. The apex of the conical body is disposed adjacent to the end of the-pipe. 20 which leads into the bowl and the lip 26 overlies the wick 15. The combined air deflector. and flame spreader is supported in this position by means of flat ribs'or vanes 27 integral with or suitably secured to its periphery at spaced angular intervals and having shoulders 28 which rest on an upstanding flange 29 provided on the bottom wall 4:. The vanes 27 are vertically disposed v and these vanes serve not only to support the combined air deflector and flame spreader in position but also to prevent swirling or vortical movements in the an currents, while constraining them to flowdown over and across the upper end of the wick.

as illustrated to advantage 'in Figures 2"a-nd 3.-

The lower end of the wall 8 and the upstanding flange 29 define an oil pocket ort-rap 31 between them which serves to. collect any oil overflowing the wall'8. The oil collecting in trap 31 flows through pipe 32 to the conv trolebox 1 1 wherein-it operates a safety valve.

The combined air deflector and flame spreader 23 is provided with a handle. 35 in a-recess.36 formed in the upper end thereof so'that the combined air deflector and flame spreader may be readily taken from and placed in positiono-n the burner. I

In operation the oil flows in through the pipe 10 throughthe space 9 and thoroughly and] evenly saturates the wick 15. The air flows in through the pipe 20 and is. constrained by the combined air deflector and flame spreader and its vanes 27 to flow dow-n across: and over the upper end of. the wick thereby projecting an even and uniform blaze from theburner or around the same and=.insures completeand thorough combustion of thefuel. In the space-9' and during its pas sage to'the wick 15-the oilis preheated dueto therfact that the heat of the flame is taken up to someextent by the ribs 30, flange-3 and body 2 of the bowl.

l/Vhat I claim is 1 An.- oilburner comprising albowli shaped 7 body having an outwardly and upwardly flaring. flange at its upper end: and provided with a central. opening inits bottom, an' up standing. flange surrounding'said openingaan inner: vertical wall extending upwardly from the bottomrof said. body'and spaced laterally from the inner face of the. side wallsiofsaid body to form a wickreceiving'chamber, an air supply" pipe. connectedto discharge into said burner through said central openingand a1 combined air and flame deflector having laterally spaced depending vanes resting on the flange surrounding the central openingof said'bodyto support the deflector andtozprevent swirling ofthe air currents; V
