UNITED STATES PATENT OFFICE FLAME DIRECTOR FOR USE WITH AN OPEN END POT TYPE OIL BURNER James L. Breese, Santa Fe, N. Mean, assignor to Breese Burners, Inc., Santa Fe, N. Mex., a. corporation of Delaware Application November 24, 1947, Serial No. 787,824

Claims. (Cl. 158-91) My invention relates to an improvement in liquid fuel burners and has particular application to flame directors for oil burners used in cook ranges.

One purpose is to provide means for varying the direction of delivery of flame from a pot type burner.

Another purpose is to provide means for varying the direction of delivery of flame in a burner used in a cook stove assembly.

Another purpose is to provide improved means for varying or controlling heat delivery to various parts of a stove or heating assembly. 4

Other purposeswill appear from time to time in the course of the specification and claims.

My invention is illustrated more or less diagrammatically in the accompanying drawings wherein:

Figure 1 is a vertical section through the burner and associated parts;

Figure 2 is a section along the line 2-2 of 2 I1 is the burner pot, is enclosed 'within the housing II, is also mounted on the flame ring l0, and is partially closed as is the housing I I by the flame ring I0. Disposed in the wall of the pot I'I are a plurality of primary air inlet apertures l8.

They are located at various points therein and permit the entrance into the pot of air under pressure from the fan l6. i9 is a deflector ring encircling the inside of the pot between the primary air inlet apertures and the flame ring. 20, 2| are two parallel rows of secondary air inlet apertures more closey spaced than are the primary apertures and the row 20 being in line with the deflector ring l9 so that air passing through the apertures 20 is guided by the deflector ring I9 to impinge upon the jets of air entering through the apertures 2 I. 23 is an oil cup. It is contained within the pot I1, is open at the top and provided with a heat conducting belt 24. Extending laterally in the pct is an oil supply pipe which passes through the wall of the hous- Figure 1; ing H, the wall of the pot l1 and supports the Figure 3 is a section along the line 3--3 of cup 23 in place in the pot wall supplying fuel to Figure 1; the cup from any suitable control and supply Figure 4 is a section along the line 4-4 of means not here illustrated as they form no part Figure 1.; of my invention.

Figure 5 is a section along the line 5-5 of The member 24 extends back from the cup 23 Figure 4; toward the closed end of the pot, the pot being Figure 6 is a side elevation of the supporting bracket looking from the side of the stove on which the bracket has been mounted; and

Figure 7 is a section along the line 11 of Figure 6.

Like parts are indicated by like characters throughout the specification and drawings.

Aindicates a stove or range with which my burner is to be used. I indicates the combustion chamber which may have a grate of the usual coal or wood type, as the case may be. Combustion chamber is closed at the back by wall 2, apertured at 3. Combustion chamber also connects with a flue 4. 5 is the top of the stove having one or more removable lids 6 and on which pots and pans to be heated may be placed. The products of combustion circulate from the combustion chamber through the flue 4 or any other suitable manner to heat the stove.

The burner itself is generally indicated at B.

The burner comprises an annular ring ID. This ring is accurately called the flame ring. Mounted on this ring is an outer cylindrical housing ll having an apertured end l2. Mounted on this apertured end is a bracket l3 which carries a motor I l. The motor has a drive shaft l 5 which carries a fan It contained within the housing I I.

closed at a preferably curved wall 26, conducting heat from the cup toward the closed end of the pot. 21 is a shield on the outside of the pot masking the fan It to protect it and the motor from the heat of the pct. 28 indicates brackets positioning the pot in the housing. 29 is a sleeve in the wall of the housing 11 in register with the aperture 30 in the housing II, which is normally closed by a plug 3|. The purpose of this is to provide access to the pot so that burner may be lighted.

The supporting bracket for the burner is indicated generally at C in Figure 6. This bracket comprises a central collar adapted to penetrate the aperture 3. A flange 4| extends laterallyfrom this collar 3 and is provided with a plurality of arms 42 which, by means of sleeves 43 and bolts 44, support the flame ring Ill spaced away from the flange 4|. Screw seats 45 on the opposite side of the flange 4! defined by walls 46 rest against the wall 2 being held there-against by bolts 41 to hold the burner in register with the aperture 3.

Mounted in the sleeve 40 is a collar 50. This collar is outwardly flanged at 5| with an extension flange -52 largely bridging the gap between II the flange 4| and the flame ring III. A handle 53 extends outwardly from this flange beyond the burner so that the flange may be rotated. Extending inwardly from this flange through the aperture 3 into the combustion chamber is a deflector blade 54 integral with the flange 50. This deflector blade is inclined to the axis of the pot, is curved as indicated in Figures 1 and 3, and may be adjusted in position rotating about the horizontal central axis of the pot by manipulating the handle 53.

Without this deflector the flame passing through the flame ring from the pot into ,the combustion chamber in the stove would tend to continue to deliver along the pot' axis. It frequently happens that the cook needs to have a special application of heat at some particular place on the stove and he always wants to have the top of the stove hotter than the lower portion, so if this deflector is left in the full line,

position, shown in Figures 1 and 5, the flame will be deflected upwardly against the upper surface of the top wall of the stove 5, and deflected away from the lower portion of the stove, the grates and the like. However, it frequently happens that the cook wants to deflect the flame laterally and when he does, all he has to do is to rotate the deflector by manipulating the handle 53 so that the flame, for instance, goes in the general direction as the arrow shown in Figure 5. The handle as shown in Figure 2 is free to move through an angle of slightly less than 90 which gives ample space for such adjustment.

I claim:

1. For use with a pot type oil burner having an open end, a flame ring adapted to partially close the open end, a supporting ring parallel to and spaced from the flame ring, a rotatable ring supported between the flame and supporting rings, all three rings being concentrically apertured, the inner diameter of the flame ring being less than the inner diameter of the supporting ring, a flame deflector plate, extending diagonally, outwardly from one side of the supporting ring adapted to intersect the axis of the pot and the three rings.

2. For use with a pot type oil burner having an open end, a flame ring adapted to partially close the open end, a supporting ring parallel to and spaced from the flame ring, a rotatable ring supported between the flame and supporting rings, all three rings being concentrically apertured, the inner diameter of the flame ring being less than the inner diameter of the supporting ring, a flame deflector plate, extending diagonally, outwardly from one side of the supporting ring adapted to intersect the axis of the pot and the three rings, the effective cross-sectional-area of the flame deflector plate projected on a plane perpendicular to the axis being less than the cross-sectional area of the aperture in the flame ring.

4. For use with a pot type oil burner having an open end, a flame ring adapted to partially close the open end, a supporting ring parallel to and spaced from the flame ring, a rotatable ring supported between the flame and supporting rings, all three rings being concentrically apertured, the inner diameter of the flame ring being less than the inner diametenof the supporting ring, a flame deflector plate, extending diagonally-,-

outwardly from one side of the supporting ring adapted to intersect the axis of the pot and the three rings, the deflector plate being concave toward the burner.

5. For use with a pot type oil burner having an open end, a flame ring adapted to partially close the open end, a supporting ring parallel to and spaced from the flame ring, a rotatable ring supported between the flame and supporting rings, all three rings being concentrically apertured, the inner diameter of the flame ring being less than the inner diameter of the supporting ring, a flame deflector plate, extending diagonally, outwardly from one side of the supporting ring adapted to intersect the axis of the pot and the three rings, the effective cross-sectional area of the flame deflector plate projected on a plane perpendicular to the axis being less than the cross -sectional area of the aperture in the flame ring, the clearance between the projected area of the deflector and the aperture in the flame ring increasing from its connection with the flame ring toward the opposite side of the circle defined by the flame ring.
