A combustion pan 38 is provided below the neck and is "supported therefrom {by arms-39 which hook over the lugs 3'7. This pan is'disposed abovethe level of the plate 16 andabout midwaybetween the lower end of the neck 36 and the bottom ofthe cup 19. As will bcinoted the pan is quite shallow andis composed of thin material, preferably sheet iron. H Fuel flow through the'pipe32f is'controlled byv a va1ve39 10 cat'e d ext-e na'lly of the furnace and held normally gin open position by a springfiO surrounding, the" valviestem 41 One endrof' a leyer41 is pivotally'fconiiected 'in any.,suit-' able manner to the Valve (body and bears at an intermediate point tilts-length -'upon*=the vane sienna Tossed the'freend f the lGYQv ll. a p ll "i i i to receive any discharge pipe 241;.

in Fig. there are shown several slight modifications, any or all of which are of equal importance with and may be substituted for corresponding parts as illustrated in the preceding figures, no one form being preferred over others. The fuel pipe 32 instead of coming up through the spider leg is introduced through an opening 32 near the top. The combustionpan 38 is supported from below on lugs 19 formed on the cup The pipe 33 projects entirely through the air outlet 27 and carries a perforated air mixing and deflecting plate it which directs the incoming air in a plurality of streams or jets into different parts of the oil gas or vapor arising from the plate 38, thus giving very perfect. combustion. The legs maybe omitted and the burner set down on the plate 13.

The operation of the device is extremely simple. Oil is admitted slowly through the pipe 32 and drops into the pan 38, where it is ignited and burns. Air enters the combustion chamber of the furnace around the plate 16 and also flows up through the spider legs and thence downwardly through the neck 36. it will thus be observed that the movement of air through the opening 27 is opposed to the normal direction of the flame of oil burning in the pan 38. The result is that the flame is flattened out and escapes between the legs of the spider and under the loafiles 28. This flame soon warms the spider legs and consequently the air flowing therethrough. so that the temperature soon reaches and is maintained at a point where a very good combustion is obtained. If any supported in. position through the excess of oil is supplied, the shallow pan very soon overflows and the surplus oil is caught in the cup 19 and runs away through the pipe 21. Any flame is extinguished as the oilpasses through the pipe and, even where this is not the case, the formation of a trap in the pipe would prevent the es cape of any flame or hot gases.

presses the valve stem 42 and. closes'oii the oil supply. It the burner should be improperly regulated. the gradual accumula: tion of oil in the'pail 43 will gradually close the valve 87 until only the proper amount vof 011 is feeding to the burner.

lVhen it is desired to clean the apparatus,

this may be very readilyaccomplished by The surplus 011 runs through the pipe QLand into the pail 43 where it is collected. If for any rea removing the cover 30 and screwing out the plug 33, thus permitting the introduction of a brush to clean out the parts 33 and 33. The cup 19 and plate 38 may be removed by a slight rotary motion which will disconnect them from the members supporting them. The resilient support for the funnel 22enables the same to be pressed out of the path of the pipe 21 during'disconn'ection of the cup 19. The burner is very clean to operate, especially when lighting the same owing to the. fact that the plate 38 is of thin material which ,rapidly heats up to a point where the oil will vaporize on contact therewith. This feature eliminates much soot when theburner is being lighted and also overcomes a prolonged operation of the burner or-discharge of gas after the support has been cut off.

While the burner has been shown with a three-legged spider and of circular form and has been described in connection with a particular heating apparatus, it-will be understood that the invention is not limited in any of these respects, as the shape of the spider and the number of legs thereof may be changed at will and the invention may be applied to cooking or other apparatus. It will also be understood that while the de vice has been shown with only a single conbustion plate 38 in the spider that a single spider may contain two or more combustion plates.

Having thus described my invention, what I claim is 1. In an oil burner, an air heating and conducting element comprising spaced conduits extending upwardly from their inlet ends and downwardly to a discharge point over. the combustion Zone, and deflecting plates arranged between said conduits.

2. A device according to claim 1, in which the deflecting plates are arranged at an inclination.

3. In an oil burner, the combination with an air conduit having a downwardly directed outlet, a combustion plate below said outlet, and a drip cup below the combustion plate, of a fuel supply pipe including a downturned extremity extending into the air con duit outlet. a support spanning the air conduit, a bushing passing through said support and into the fuel supply pipe, a plug in said bushing giving access to the down-turned 6X- tremity of the pipe, and a removable plate in said conduit giving access to said plug and to the outlet of the conduit.

4. In an oil burnerfan air conduit, a combustion plate in alignment therewith, and

an air deflecting plate interposed between the mouth of the conduit and the combus tion plate.

5. A device of the class described comprising an air conduit having a downwardly directed outlet, a fuel supply pipe passing through said outlet, combustion plate below the outlet in alignment therewith, and an air deflecting plate interposed between the air conduit and combustion plate.

6. A device according to claim 5, in which the air deflecting plate is adjustably mounted and movable relatively to the mouth of the air conduit and the combustion plate.

7 A device according toclaim 5, in which the deflecting plate is apertured to divide air emerging from the conduit into a pluforated and adjustably mounted on the fuel supply pipe.

In witness whereof, I have hereunto set my hand.
