This invention relates to oil burners and in accordance with the present invention an improved construction of fuel mixer and burner for heating furnaces, cooking stoves and the like is provided; and the invention together with its numerous objects and advantages will be best understood from a. study of the following description taken in connection with the accompanying drawings where- Figure 1 is a top plan view of the burner.

Figure 2 is a vertical sectional elevational view taken substantially on the line 22 of Figure 1.

Figure 3 is a side elevational view of a perforated drum forming part of the invention.

Figure 4 is a top plan view of a base and basin integral therewith.

Figure 5'is a top plan view of a combined burner plate and tray and Figure 6 is a view partly in section and partly in elevation of a modified form of combined burner plate and tray.

In its preferred embodiment, the preferred invention comprises a base 10 having a plurality of relatively spaced standards 11 rising therefrom adjustable vertically and slidably engaged with the standards 11 are tubular standard extensions 12, and set screws 13 are provided as shown for securing the tubes 12 at the desired adjustment.

Carried by the tubes 12 for vertical adjustment therewith is a base 14 of suitable material, and the same adjacent its periphery is provided with a circular series of openings 15, some of which serve as air inlet openings, as will be hereinafter made more apparent, while other of the openings accommodate the tubes 12 as shown in Figure 2. The tubes 12 on their lower ends having screw threadedly engaged therewith collars 16 that engage against the under side of the base 14, and these collars 16 are apertured for accommodating the screws 13. Manifestly to raise or lower the base 14, set screws 13 are loosened, the tubes 12 then adjusted as desired, and the screws 13 subsequently tightened for securing the tubes 12 and the base 14 at the desired adjustment.

Formed above the base 14 are chambers 17 and 18 respectively, the outer chamber 17 serving as what may be termed an air chamber, the bottom of which is formed by the apertured portion of the base 14; while the innerachamber 18 serves as a combustion and mixing chamber. The chambers 17, 18 are formed by inner and

outer drums

19, 20 provided with perforations 21, 22.

The base 14 is provided on its top side with a formation 23dished out to form a basin 24 that is provided with an internal annular shoulder 25 upon which rests the lower edge of the drum 19. Adjacent its peripheral edge the base 14 is also provided with a shoulder 26 upon which rests the lower end of the outer drum 20.

An annular plate 27 closes the top of the chamber 17 being disposed about the inner drum 14 and supported by the outer drum 20. The plate 27 adjacent its outer circular edge is provided with a shoulder 28 which rests on the upper edge of the drum 20; and the drum 18 adjacent its upper edge is en-. larged to provide an external shoulder 29 resting against the top side of the plate 27.

Through a substantially centrally located aperture in the base 14, there extends a fuel supply pipe terminal 30 that is provid ed with exterior screw threads for substantially its full length, and the referred to aperture in the base 14 is also provided with screw threads coa-cting with the threads ofthe terminal 30 so that the latter may be secured at the desired vertical adjustment.

A to burner plate 31, which is in the nature o a rimmed disk, is provided in the bottom thereof with a threaded opening and is screwed on the upper end of the terminal 30. The rim of the plate 31 is provided with apertures 32 through which sur lus oil may spill. The surplus oil from the urner plate 31 is caught by a tray 33; and the tray 33 is in the nature of a rimmed disk of slightly greater diameter than the burner plate 31, and is provided in its bottom with a centrally located threaded opening, and is screwed on the supply pipe terminal 30 below the burner plate 31.

The basin 24 serves as a catch basin for 10.

surplus and waste oil, and said basin is provided with a drain pipe terminal 34 that is screwed into a threaded opening provided in the bottom of the formation 23; it being understood that the terminal 34 may be readily coupled to a drain pipe (not shown) leading to a suitable receptacle. It will be noted that the upper end of the terminal 34 is in a plane above the bottom of the catch basin 24 so that the oil may accumulate in the basin 24 sufficiently to. permit the accumulation to cool before passing into the drain pipe.

Instead of having the individual burner plate 31 and tray 33 a structure such as shown in Figure 6 may be substituted, the latter structure being a combined burner plate and tray and includes a substantially cylmdrical body 35 of metal or other suitable material and having a central orifice 36 extending therethrough; the orifice 36 at the bottom end of the body 35 being diametrically enlarged and screw threaded as at 37 whereby provision is made to readlly screw the member 35 on the upper end of the supply terminal 30. The body 35 on its upper end is provided with a radially tapering recess 38 gradually increasing in depth from the central opening 36 to an outer vertical annular marginal or peripheral wall 39, formed by recessing the upper face of the body 35 and located at the periphery of the same. Formed integral with the body 35 is a tray 40 for catching the overflow from the recess .38; and the tray 40 is formed by diametrically enlarging the body 35, and providin g the upper face of the enlarged portion with an annular groove 41.

Disposed adjacent the upper end of the drum 18 is .a flame baffle or spreader plate 42 that is provided on its under side with a substantially conical depending formation 43, while on its upper side the plate 42 is provided with a lug 44 having a horizontal opening 45 extending therethrough. A supporting rod 46 includes a vertical part. the lower end of which is suitably coupled with the upper end of one of the tubes 12 through the medium of a coupling sleeve 47; and the vertical portion of the rod 46 merges into a horizontal or laterally extending portion 46a that has an end thereof extending into the opening 45., A set screw 46 is provided as shown in Figure 2 for securing the spreader plate 42 at the desired adjustment.

Fuel, in the form of any type of high or low grade oil is fed from a suitable source of supply to the burner. The oil from the fuel line passes up the fuel line terminal 30 and spreads out over the burner plate as it flows from the terminal 30. The oil on the burner plate is ignited by the application of a match thereto or in any other suitable manner. After the burner plate becomes heated the fuel will be immediately converted to gaseous form and burned. As is apparent air enters the chamber 17 through the perforations 22 and also'through the openings 15, and the air in the chamber 17 is heated, and passes from the chamber 17 into the combustion chamber 18, and the incoming heated air mixes with the vapors of the fuel Within the chamber 18 so that combustion is complete and the maximum quantiy of heat is released.

In actual practice it is intended to have the drain pipe (not shown) with which the drain pipe terminal 34 is associated to be so connected with a valve (not shown) controlling the supply of fuel to the burner as to utilize the u-nburned oil for shutting off the valve and preventing further feed of oil to the burner when the burner is functioning properly.

Even though I have herein shown and described the preferred embodiment of the invention, it is to be understood that the same is susceptible of further changes, modifications and improvements coming within the scope of the appended claims.

Having thus described my invention, what I claim as new is:

1. An oil burner of the class described comprising a base, vertically adjustable supporting means for the base, said base being provided with a formation forming a drip basin having an aperture, a supply pipe terminal extending vertically upwardly through said aperture, a burner plate connected with the upper end of said terminal, the upper end of the terminal being adapted to direct oil on to said burner plate, and a lower tray on said terminal of slightly greater diameter than the burner plate and adapted to receive fuel therefrom, a rod extending upwardly from said base, a flame spreader plate disposed above the burner plate, and means for adjustably mounting the spreader plate in a horizontal position on said rod.

2. In an oil burner, a base provided with a central formation forming a drip basin, and being also provided with a circular series of openings concentric to said formation, a perforated drum having its lower edge resting on said base, a second perforated drum having its lower edge resting on said formation about said drip basin, a fuel supply pipe terminal extending vertically upwardly through said formation centrally of said drip basin, a drain supply pipe terminal connected with said drip basin, a burner plate mounted on said supply pipe terminal, and a lower tray mounted on said supply pipe terminal below said burner plate.

3. In an oil burner, a base provided with a central formation forming a drip basin, and being also provided with a circular series of openings concentric to said formation, a perforated drum having its lower edge resting on said base, a second perforated drum having its lower edge resting on said formation about said drip basin, a fuel supply pipe terminal extendin vertically upwardly I through said formation centrally of said dri basin, a drain supply pipe terminal connecte with said drip basin, a burner plate mounted on said suppl pipe terminal, a lower tray mounted on sal supply pi e terminal below said burner plate a sprea er plate adjacent the upper end of the second named drum, and supporting means for said late.
