Fig. l isa vertical mid-section of a modified form of the deflector and cap there-under to which said deflector is secured.
Fig. 5 is a transverse section looking upwardly from the line 5-5 of Fig. 4.
Referring in detail to the drawing, bowl includes a rim portion 5 which is supported upon the floor portion 6, said floor portion having a peripheral horizontally in the base of which is an 1 Claim.
d wherein the oil d multiple the class to which drawing which deemed to be med as a the burner extending flange I upstanding annular lip 8, thus providing a supporting and centering means for removably mounting said bowl rim 5. The floor portion 6 of the bowl is provided with an upwardly inclined peripheral portion 9 which,
in combination with the upstanding lip 8 affords a dish-like structure for containing the oil body H, and the drainage pipe i2 is provided to receive a pipe it, the mouth of said drainage pipe being slightly below the top of the lip 8 in order that, at no time, the liquid will rise so high within the burner bowl as to overflow the upper edge of said lip.
-The floor portion 6 of the burner bowl is furnished with a cup-shaped central downwardly extending part 15 which, by means of a set screw it, is securable to the upper end of an air supply tube W. The cup portion l5 above to the pipe H, is supplied with a tubular upstanding central flange it! thus affording an annular oil chamber 2i between said flange i9 and the wall of' the cup l5 which is spaced outwardly therefrom. With the lower portion of the chamber 21 communicates an oil supply passage 22 into which is screwed the oil supply pipe 23. A drainage plug '24 may be provided for this passage.
A combined oil and air spreading structure 2% is mountable over the open upper end of the flange l9 as shown in Fig. 2. Said structure t5 comprises a body portion 2G of a tubular character furnished near its lower end with an outwardly directed peripheral flange portion 21 the lower surface of which is provided with a series of equally spaced radially projecting ribs or projecting portions 28 shown in bottom plan in Fig. 3, said ribs '28 preferably being outwardly tapered or converging and forming therebetween diverging oil passages whose continuity is only slightly broken by the tips of said ribs. The lower side of the body Z6 is also furnished with a downwardly extending annular flange 39, the thickness of said flangebeing considerably less than the width of the annular oil chamber 2-H, thus aifording an annular oil space 3! outside of said flange which communicates with the spaces ZBs betWeen the ribs 28. As shown in Fig. 3 the annular body 26 is provided with a plurality of outwardly directed spacing lugs 25 which maintain the parts in the spaced relation shown in Fig. 2. The annular body 26 above its basal flange 30 is of a proper diameter to flt properly around the annular flange I9. Within the flange 36 there is a space 32 between it and the upstanding tubular flange l9. Saidspace 32 is provided for convenience in assembling. It
' avoids the necessity of machining the parts adjacent thereto.
Tracing the course of the oil through the structure which has been described, the oil enters through the pipe 23, accumulates in the annular oil chamber 2| within the cup I and after filling said chamber passes up through the annular oil space 3| after overflowing which it passes horizonally outward through spaces 283 between the ribs 28 and then collects in a shallow annular body I upon the bowl floor 6. In order to direct an effective oil vaporizing stream of air down upon the body of oil H the tubular oil spreader member 26 is surmounted by a spider 25s preferably made integral therewith, said spider having a body portion 33 which carries an upwardly convexed spreader plate 34, said spreader plate preferably being provided at its center with an unwardly directed apertured lug 35 through which a suitable tool may be inserted for lifting the entire structure 25 from the underlying part of the oil burner construction.
The detachable rim portion 5 of the burner bowl may be made of a material adapted to withstand higher temperatures than the floor portion of the bowl. This rim portion 5 is subjected to the most intense heat during the operation of the device. It is preferably of a concaveconvex character with its concave face directed downwardly in order to impart a whirling or eddying effect to the air as it is delivered from the deflector 34.
In Figs. 4 and 5 is shown a modified combined air deflector and oil feeding structure which may be substituted for the structure 25 shown in Fig. 2. This modified structure includes an annular base member 40 having at its lower end a downwardly directed skirt or annular flange 4| which is exteriorly provided with a plurality of spaced vertical centering ribs or lugs 42. At the upper end of the flange 4| a horizontal peripheral outwardly directed flange 43 is provided and each rib 42 of the flange 4| has a horizontally extending portion 44 which overlies said flange 43. The result of this construction is that when the structure shown in Fig. 4 is substituted for the structure 25 of Fig. 2 a series of radial oil outlet passages are provided owing to the fact that the rib portions 44 rest upon the upper surfaces of the floor 6 and at the same time the outer faces of the rib portions 42 abut against the inner side of the cup wall l5.
At the top of the member 4| of Fig. 4 is provided, integral therewith, a spider or crossbar 46 in the center of which is secured an upstanding screw stem 41. Upon the upper end of this stem 41 screws the body portion 50 of the modified deflector 5|. Said modified deflector has a downwardly directed concave face which is provided with a plurality of spirally arranged air whirling ribs 52.
Both of the deflectors shown direct the air downwardly against the annular oil body II in a current shaped as an inverted funnel. The air may be delivered to the concave side of either of the deflectors shown with suflicient force to be deflected downwardly in a current powerful enough to extend out or attenuate in a horizontal direction the annular oil body I! and cause its outer portion to creep up to or somewhat beyond the periphery of the floor 6 of the bowl. In this extended condition vaporization will take place more rapidly and better combustion will be secured. It will be observed that the shoulder 8 along the juncture of the bowl rim 5 with its body portion, is so positioned as to guard against leakage of the liquid fuel.
As a convenience for lighting the burner an annular seat or groove 21a is provided in the upper face of the spreader flange 21 and in said groove is placed a strip 21b of asbestos or other incombustible, absorbent material, small passages 210 being provided adjacent to said groove to receive small wires 2711 to hold said strip 21b in place and to allow oil to ascend from the passages 28s into said groove. When an ignitable liquid fuel is poured or fed into the groove 21a it will be absorbed by the strip 2'") and then by applying a flame or other ignition means to said strip, an annular band of fire will result adjacent to the ,oil body I causing thorough ignition of the fuel under the encouragement of the air stream directed downwardly by the deflector.
It should be understood that the present disclosure is for the purpose of illustration only and that this invention includes all modifications and equivalents which fall within the scope of the subject matter claimed.
What is claimed is:
In an oil burner, a burner bowl having a base portion provided with an upstanding central flange around which is an annular oil chamber, an oil and air spreading member having an annular lower portion which is fitted around the upper end portion of said flange, said spreader having in its lower portion an outwardly directed peripheral flange having downwardly projecting radial ribs which rest upon the floor of said bowl when the spreader is fitted upon said flange, said bowl having an annular space to provide for collecting an annular shallow body of oil around the outer ends of said ribs, means to supply oil to said annular oil chamber and thence to the spaces between said ribs and to said shallow oil body, an air spreading deflector mounted upon the upper portion of said spreader body in a position to direct a. current of air of an inverted funnel shape down upon said shallow body of oil, and means to supply a current of air against said deflector to be deflected thereby against said shallow oil body.
