OIL BURNER.

Application filed March 6, v1926. Serial No. 92,899.

This invention relates to oil burners and more particularly to an apparatus designed for burning crude or otherwise waste 011. With my improved apparatus I can burn oil which has been removed or discarded from automobile crank cases or other analogous oil used for lubricating purposes, such oil being practically nonunflammabie until vaporized by the action of heat.

A further objectis to provide a burner which may be used in a furnace or utilized for heat in connection with. any apparatus and which ensures a proper combustion and gives excellent results.

l/Vith these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts which will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings- Figure 1 is a view, partly in elevation and partly in section, illustrating my improved burner in operative position in a furnace;

Figure 12 is a view in vertical section through the block shown in Figure 11;

Figure 13 is a view similar to Figure 1., illustrating a modification.

In Figure 1, I illustrate my improved burner located within an ordinary domestic furnace 1, the oil being supplied by gravity from artank 2 through a pipe 3. In this pipe 3 I provide a cut-off valve 4 and a needle valve 5 to regulate the flow. .Aiso in this pipe 5 I locate a relief valve 6, the

latter having a perforated cap 7 thereon with a screw plug 8 adjustable on the cap so as to regulate the amount of opening for best service.

I shall now describe my improved burner in detail. 9 represents a base block which may be of metal or it may be of firegbrick, as desired. This base block may be supported upon the grate 10 of the furnace and is formed on its under face with webs I1 spacing the main portion of the block above the grate so as to allow a free draft vof air around the same. On this base block. 9 I support a series of superimposed bricks 12, 13, 14 and 15, although of course it is to be understood that I do not limit myself to the particular number of bricks employed as this may be varied to suit conditions.

The bricks 13, 14 and 15 are substantially alike, each brick having webs 16 on its outer face extending vertically and tapering in form, the outer edges of said bricks being tapered, as shown, or, in other words, largest in diameter at their lower ends and decreas ing in diameter to their upper ends, said bricks 13, 14 and 15 having enlargements 17 on their upper ends fitting in correspondingly shaped recesses 18 in the lower faces of the bricks, the recesses and enlargements being so formed as to cause the webs 16 on the outer edges of the bricks torhave a staggered relationship, as shown clearly in F igures 6 and 7. p

The upper brick 12 also has a recess 18 in its lower face to receive theenlargement 17 on the upper brick 13. This upper brick 12 is of truncate conical form with its smaller end uppermost, and is provided in its smaller end with a recess 19. A cap or dome 20 is located on the upper end of the pile of brick and this cap or dome may be of metal or any other suitable material and has a flared base portion 21 fitting over the upper end of the upper brick 12.

This cap piece 20 is open at its upper end and is provided in opposite sides with longitudinal slots 22 adapted to receive arms 23 projecting from opposite sides of a deflector 24. This deflector 24 has its lower end fitting in the recess 19 of upper brick 12, and the top orupper portion of said deflector is of semi-mushroom shape, as shown at 25, and'is located directly below my improved vaporizing nozzle 26. This nozzle 26 has a threaded nipple 27 in one side wall which receives the end of pipe 3. The nozzle and the oil will flow down the pipe 3 26 discharges downwardly directly upon the top ofdefleetor 24 and is provided in its top and side walls with any desired number of orifices 27 through which vapor or gas formed by the vaporizing process may burn.

The bricks 13, 14 and and the base 9 are provided with openings 28. through which excess oil may flow and also through which air may pass in its upward draft. All the bricks may be provided with shoulders or supporting webs 29 so as to hold the pile of bricks in proper assemblage.

In Figures 11 and 12 I illustrate a modified form of base member 30 which constitutes a pan or receptacle having an upwardly V projected conical portion 31 with openings" 32 therein for the passage of air. This modified form of device has feet 33 on its lower edge to support the same wherever desired.

The operation of my improved burner is as follows Kerosene or other inflammable fluid may be deposited in a recess 34 of base 9, or it may be poured over the bricks to saturate them, and ignited. This burning fluid will not'only heat up the bricks but will heat the vaporizing nozzle 26 so that when the desired temperature is reached the valves 4 and 5 are opened as much or as little as desired, into the nozzle 26. A portion of this oil will be vaporized in the nozzle and will burn through the orifices 27. Any back pressure of vapor or gas will escape through the valve 6. The oil dropping from the nozzle 26 will fall on the deflector 24 and will be distributed by the same over the surface of the brick 12 and will flow down between the staggered arrangement of webs 16 on the pable of sustaining the necessary combustion and heat without cracking.

As above stated, my apparatus is partrc- V ularly designed for burning discarded lubrieating oil, which is not very volatile, which is not readily burned, and which in theqtrade V is known as non-inflammable so that dan crank case oil, is dropped from a 'P-head nozzle 39 carried by a supply pipe 40. In this supply pipe 40 a valve 41 is provided to regulate the flow of oil, and a relief valve 42, corresponding to the relief valve 7, is also provided. This pipe 40 communicates with the lower portion of a water trapping receptacle 43, a supply pipe communicating with the upper portion of said receptacle. 45 is a drain cock to drain off water from the receptacle 43, and 46 is a pet cock at the upper portion of the receptacle 43 by means of which it can be whether or not the oil is flowing freely- The purpose of this receptacle 43 is to catch and hold water which may be in the oil and as above stated I may use ordinary crank case oil which frequently contains water, and this water will be entrapped in the receptacle 43. l urthermore, it will be noted that this receptacle 43 is located relatively close to the stove or heater so that it receives a certain amount. of heat which will prevent the liqaid from freezing and will have a tendency to thin the oil and allow it to flow freely.

In starting this form of my burner, oil or other combustible is located in the pan 36 and ignited, and this flame will, not only heat the bricks but will heat the nozzle 39 and the pipe 40, so that when the oil is turned on it will burn as soon as it hits the bricks, or will saturate the bricks and burn determined 7 evenly so that the maximum of heat units is utilized from the fuel employed. 7

The porous quality of the bricks ensure full vaporizing of the oil and the bricks retain their heat, so that while I have illustrated one form of brick it is obvious that the invention is not limited thereby, and various slight changes and alterations might be made in the general form of the parts described without departing from the invention, and hence I do not limit myself to the precise details set forth but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of the appended claims.

I claim:

1. A burner, including a base member, a pile of superimposed bricks thereon, an open cap member on'the upper brick, a deflector supported in said member, a discharge nozzle directing oil onto said deflector, the upper brick having a recess receiving the lower end of the deflector, the upper end of the deflector being of eneral mushroom shape, and outwardly projecting arms on the deflector and said cap member having slots therein receiving the arms.

2. A burner, including a base member, a pile of superimposed bricks thereon, an open cap member on the upper brick, a deflector supported in said member, and a discharge nozzle directing oil onto said deflector, said bricks having longitudinally extending webs on their outer faces, the Webs of the several bricks being located in staggered relationship.

3. A burner, including a base member, a pile of superimposed bricks thereon, an open cap member on the upper brick, a de flector supported in said member, and a discharge nozzle directing oil onto said deflector, said bricks having longitudinally eX- 'i tending Webs on their outer faces, the webs of the several bricks being located in stagadjacent faces holding the bricks in proper relationship to each other.
