sclaims.

My invention pertains to an improvement in oil burners.

An object of my invention is to provide;v in an oil burning stove, auxiliary means for improving 5 the combustion eiect in the stove. .f

A further object of my invention is to provide a device of this character which momentarily retards the flame or the ow of unburned gases so that the same can be then more completely mixed l with air to insure a more `complete combustion.

A further object of my invention is to provide a simple device of this character which can be adjusted for different conditions for supplying a greater flow of air or less as desired.4

A further object of my invention is to provide a combustion improving device which can be easily installed. Y A. further Vobject of my invention-is to provide a device of this character which will not get out 20 of order, due to the absence of movable parts and the like.

A further object of my invention is -to provide a device of this character which can be constructed at a reasonable cost.

With these and other objects in view, my invention consists in the construction, arrangement and 'combination of the various parts of my de-` vice, whereby the objects contemplated are attained, as hereinafter more fully set forth, point- 30 ed out in my claims, and illustrated in the acc'mpanying drawing, in which:

Figure lis a sectional view taken longitudinally through an oil burning stove,

Figure 2 is an enlarged sectional detail taken 35 along the lines 2 2 of Figure 1,

Figure 3 is a slightly modied form, Figure 4 is -a sectional view taken along the lines .4 4 of Figure 2, and

Figure 5.is a sectional view taken substantially 40 along the lines 5 5 of Figure 3.

I have'used the character I 8 to designate an upright vertical flue which includes the cap' II.

A further iiue I2 which acts as a chimney is spaced from the ilue I8 and attached between 45 the nues lo and lz is a suitable tank la which contains the oil supply. The tank I3 includes` ent material 2| which is situated at the bottom of the ue I0. f 'I'he material 2l is retained irr place by means of the forwardly projecting ilange member 22 which is attached to the bottom of the further horizontal combustiony chamber 23. The combustion. chamber 23 communicates directly with the iiues I0 and I2 as shown. The flame is initiated in the usual manner by lighting the absorbent member 2| upon which-the oil is drip- 10 ping`from the drip valve I8. The ame -thus initiated ,will burn within the flue I8 it being understood that suitable openings are provided for the air inlet and the burned gases will flow in the direction of the arrow-24 through the 15 chamber 23 and thence upwardly through the chimney flue I2. Air is fedinto the burner in the usual ymanner through any suitable opening in the capl I I.

Normally, the burning effect is incomplete and a great deal of smoke will pass upwardly through the .chimney ilue I2. To olset this effect, 1I provide in my device, a lengthened vertical rod 2 5 which entends upwardly and practically to the vtop of the flue I 0. The rod 25 is attached at 28 25 between the two arcuate members 21 and 28. The yarcuate members 21 and 28 form substantially approximately one-half of the circumference of the surrounding flue I0 and can be merged together with the integral anges 29. However, there-is no covering member over the upper portions of the, members 21 and 28 thereby leaving a free opening at 30 between such members.

Formed at the lowerportion of the members 21 and 28 are the substantially V shaped cutaway portions 3| leaving openings at 32, with the rear member 28 including similar openings positioned in a staggered manner as shown in Figure 4. v

In use, the points at the terminations of the V portions 3| are rested upon the asbestos or other member 2| and the rod 25 'which can be slightly bent is allowed to rest against the inner wall of the flue as shown in Figure 1. The flame is started in the burner and the following action takes place.

The members 21 and 28 act as a pair of baille plates to restrict the flame from passing too rapidly into the horizontal combustion chamber 23.

During momentary blocking of the flame, a column of air will travel downwardly in the directiomof the arrow 33 (see Figure 5) between the walls of thev flue lllf'and the outer member 28 and this column of air will. also pass directly between the arcuate baille plates 21 and 20. As

a result, a column of pure air is flowing down.- wardly at these points,` which air will mix with the unburned vapors resulting in more completeI l5 oxidation of the flame and' practically completely` burning the smoke or carbon particles. The residue then passes up the-chimney flue i2, which residue is clean and free from smoke.

1^ The staggered arrangement of-` the V-shaped .lo portions 3l also in the momentary retardation of the flame and\creates an additional circulatory effect which assists in the action .above described. The arrangement above described, Aprovides for a double column of al1" ,/which-in this case, would beseparated by Vthe outer arcuate memberl 2li. It will be noted that f the arcuate members 21 and 28 extend upwardly a 'substantial distancesov as to ,completely cover the opening of the combustion chamber 23 where it merges with the ilue I0.

A slightly modified form vof this structure is shown in Figures 3 and 5 wherein a single baille member 34 is used instead of two of the same.

The otherfeatures are identical with the excep- 25. tion, however, that in the use of the single mem-v ber, the column of airis not split into theee portions as in the modification shown in Figures l, 2, and 4. 'i f- It will now beseen that Ihavel provided a device for improving combustion in oil burners, which momentarily retards the uhburned llame portions in such burner to'allow a more complete mixing `of air therewith, and which providesfeatures for providing anfadditional column orV columns of air which mixes with the flame at the proper point. It will be seen further that I have provided such means lin a device `which can be manufactured at a reasonable cost and which `is simple in operation. Other advantages will 4g ube readily apparent Afrom the description.

Some changes may bernade in the construction and arrangement of the parts 0L my y.invention without departing from the real spirit and purpose of my invention, and it is mygintention to cover by my claims any modified forms cf structure or use of `mechanical equivalents, which'may be reasonably included within their scope.
