(Cl. 158-87) This invention relates to oil burners. and has particularly to do with oil burners in which the oil is vaporized to commingle with air to give a high combustion without the necessity of employing wicks of anycharacter.

An object of the invention is to provide a burner of this character with an improved arrangement of horizontal and vertical battles, and an improved combination and arrangement of perforated walls separating the baflles from the base of the burner whereby a high efliciency is assured.

A further object is to provide the base of the burner with removable troughs so that when the troughs become filled or partially filled they may be removed and replaced.

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

In the accompanying drawings- Figure 1 is a view in central longitudinal section illustrating my improved burner;

Figure 2 is a top plan view partially broken away to illustrate the parts below;

Figure 3 is a view in side elevation of one of our improved baflle members and portions of the vertical baffles broken away;

Figure 4 is a view in transverse section on the line 4-4 of Figure 1;

Figure 5 is a view in transverse section on the line 5-5 of Figure 1;

Figure 6 illustrates in perspective the removable troughs which we employ in the base;

Figure 7 is a fragmentary plan view of the base illustrating a modified form of coupling the troughs in the base; and

Fig. 8 is a view in section on the line 8--8 of Figure '7.

Our improved burner includes a base A, three superimposed or pyramided bailles, indicated generally by the reference characters B, C and D, and a series of concentric perforated cylindrical walls 1, 2, 3 and 4, supported on the base A and supporting the baflles above referred to. w

The base A has a central opening 5, the said base being in reality a ring the upper surface of which is formed with circular grooves 6 and 7, and in these grooves 6 and '1 we locate our improved removable troughs 8. These troughs 8 have outwardly flaring flanges 9 at their upper edges which rest upon shoulders 10 at the upper ends of the grooves 6 and 7, and the walls 1, 2, 3 and 4 above referred to rest directly upon the flanges 9 of the trough 8, and fit within the upper portions of the grooved base and insure a snug, tight juncture of parts but which, of course, are capable of separation to remove and replace the troughs in the event that the latter become filled or partially filled. This is one of the important features of our invention.

It is to be understood that the troughs 8 are to be made of any metal or composition or alloy which would best serve under the conditions, and it is obvious that by providing removable troughs instead of subjecting the base to the direct contact of the oil, which is usually hydrocarbon, it is not necessary to replace the base but only the troughs, and this is a. simple, inexpensive matter.

11 represents an oil inlet in the base A, with which a supply pipe 12 communicates, and this oil inlet 11 communicates with a pair of spouts 13 extending in opposite directions and discharg- :5 ing downwardly into the troughs 8. A simple construction is to bore the base so that these spouts 13 may be threaded therein for convenient removal. The invention, of course, is not limited to the exact manner although we believe a feed so into the top of the troughs is a preferable arrangement.

As a modification of this idea, attention is called to Figures 7 and 8 of the drawings, in which troughs 8 have openings in their bottoms, with 5 tubular screws 14 extended through the bottom of the troughs and coupled to a supply pipe 15, so that in this modified form the oil will be supplied into the bottom of the troughs. This is merely illustrative'of the fact that we do not wish to be limited to the exact manner of feeding the oil into the troughs.

The base A is provided with openings 16 so that air may pass upwardly between the walls 2 and 3, as well as into the center of the burner within the wall 1, so that this space between the walls 2 and 3 constitutes an air chamber into which air passes and commingles through the perforated walls with the vapor from the troughs for combustion. The inner wall 1 is appreciably higher or longer than the other walls, and the walls 2 and 3 are of the same height but shorter than the wall 1 and higher or longer than the wall 4.

The baille 13 ,above referred to, has an annular m5 enlargement 17' which fits into the space at the top of the air chamber formed between the walls 2 and 3, and this baflie B rests directly upon these walls 2 and 3 and has a central opening 18 appreciably larger in diameter than the diameter 0 of the wall 1, so that air and products of combustion may pass freely through this opening; furthermore, the annular enlargement 17 is formed in its lower face with inclined recesses 19 so that products of combustion passing upwardly through the walls 2 and 3 may escape laterally and outwardly; furthermore, this baiile B has openings 20 in line with the space between the walls 3 and 4, and hence while this bailie exercises its function as a baflie it does not interfere with the upward travel of the products of combustion.

The baflle B supports a series of vertical baflles 21 which project downwardly into the space between the walls 2 and 3, and these vertical baiiies 21 may constitute integral portions of the baiiie B or they may be separate members supported removahly, as may be desired. These vertical bailies 21 are of a diameter and of an area suiflcient to insure a maximum of radiation of heat thereof to aid combustion. The baflle B is formed on its upper face with radial webs 22 which support the baflle C above referred to. This baflle C is also supported directly upon the upper end of the wall 1 and is formed with a circular groove 23 to receive the wall. This baflie C has a central opening 24, and around this central opening 24 a series of vertical baflles 25, corresponding to the baiiies 21, are located. These vertical baiiles 25 extend into. the central chamber within the central wall 1 and are of such size and proportions as to give the best results.

The invention is, of course, not limited to the specific shapes of the diiferent bailles as these may be varied, but it is desirable that the battles have a large amount of heat radiating surface in their arrangement of both vertical and horizontal baiiies, and hence it is desirable that the horizontal baiiles have passage-ways or openings suitably arranged for the passage of the gases, and in Figure 2 I illustrate a form of baflie design, which is eflicient.

The baflle D above referred to is supported on top of the battle C and has a central enlargement 26 which fltswithin the center of the baiile C. The main portion of this baille D rests upon the baifle C and is formed with webs 27 and openings 28 in any suitable or desired arrangement. In any event, this baflle D'extends outwardly above the baflle C and constitutes a deflector and heat radiating medium. The arrangement of webs 29 on the baille C and openings 30 in the battle C cooperate with the arrangement of openings and webs and battles to insure a free circulation, yet offers the maximum of heat radiation for best combustion.

It will thus be noted that our improved burner has a novel arrangement of superimposed pyramided horizontal baflles above the combustion and commingling chambers formed by the walls, 1, 2, 3 and 4, so that as these vapors or gases'pass upwardly they come in contact with a large number of metal baffled portions of the burner, which insures a complete combustion.

Our improved burner is not only of extreme efliciency and utility but it can be readily assembled and taken apart as occasionimay require. Thisisimportantasaburnerofthiskindmustbe kept clean; furthermore, by providing the removable troughs we not only make it possible to lengthen the life of the base but can 1118i re clean troughs even where it is necessary to remove and replace them, as the cost of the troughs is trifling as compared with the cost of the base and the difilculty base. v

Of course, we do not wish to be limited in-the particular material employed in the manufacture of the troughs, but we believe chromium or other heat resisting metal in sheet form is the best obtainable. I I

As above stated, while we believethe preferable arrangement is to feed oil into the tops of these troughs, it is obvious that their supply of oil may be regulated in various ways, and a separate supply may be had to each or communication may be had between them.

While we have illustrated what we believe to be the preferred embodiment of our invention, it is obvious that various slight changes may be .made with regard to the form and arrangement of parts without departing from our invention, and hence we do not limit .ourselves to the precise details set forth but consider ourselves at liberty to make such changes and alterations as fairly fall within the spirit and scope of the claims.

What we claim is:

1. An oil burner including a base having a circular groove therein, an oil-receiving removable trough supported on the base and fltting in the said groove in the base, lateral flanges at the edges of the trough, and spaced concentric perforated walls supported on the base and resting on the flanges of the trough.

2. An oil burner including a base having a circular groove therein, an oil-receiving removable trough supported on the base and fitting in the said groove in the base, lateral flanges at the edges of the trough, spaced concentric perforated walls supported on the base and resting on the flanges of the trough, and a baflie resting on top of the walls and having vertical baiiies extending between the walls.
