OIL BURNER Filed Sept. 18, 19,39

INVENTOR.

I ffy/7k Patented Oct. 7, 1941 UNITED STATES PATENT OFFICE on. BURNER Frank B. Behee, Leavenworth, Kans. Application september 1s, 1939, sei-iai No. 295,434 3 claims. (ci. 12s-93) This invention relates to oil burners of the character employed in producing heat, and the primary object is to provide an oil burning heating stove that is simple in construction and eficient in operation.

One of the important aims of the present invention is to provide an oil burner having a specially formed case that presents an air chamber, a combustion'chamber, and an air duct for supplying air to the said chamber so that combustion maybe supported by preheated air entering the case of the burner through This invention has for another aim, the provision of an oil burner of the aforementioned character that is equipped with specially formed and disposed chimney, a portion of which may be displaced for the purpose oi gaining access to the vaporizer for gases evolved in the evaporator.

Other objects of the invention willl appear during the course of the following specification, re, ferring to the accompanying drawing, wherein:

Figure 1 is a vertical central sectional view through an oil burner made to embody the present invention.

Fig. 2 is ahorizontal sectional view through the same, taken on line II-II of Fig. 1; and,

Fig. 3 is a fragmentary sectional view taken on line III-' III vof Fig. 1.

In the illustrated embodiment of this invention the oil burner assumes the nature of a domestic heater orl means for heating a room or the like, and therefore, has a case 6 closed at its upper end by a cover 8 and provided at the upper `portion thereof with a flue I through which may pass the products of combustion, which must be evacuated through a chimney or the like.

Case 6 has a base I2 thereon to close the lower end thereof and partitions I4 and I6 are disposed horizontally in case 6 to divide the same into compartments, one of which is in the nature of an air chamber I8 conned below partition It and within a tray-like member 20 that is in communication with air duct 22 extending downwardly from cover 8 and longitudinally through case 6 to one side of its axis. Partition It has a series of perforations 24 arranged in an annular path around a depressed central part 26. This central part 26 is a tray-like member provided with an annular central wall 28 that forms an axial well 30, the upper endl of which is covered by a perforated dome 32.

Tray 26 has a ringhaped vaporizer 34 there- I in which is joined to supply pipe 36 by branch pipe 38 and control valve 40. Supply pipe 36 the said duct.

34 has been converted extends from any suitable source and handle 42 disposed outside of base I2, allows the operator to control the ilow of oil through pipe 36 and into vaporizer '34. y

Vaporizer 34 is hollow and circumscribes wall 28. A number of supports 44 hold the body of vaporizer 34 above the bottom of pan 26, and a plurality of 'films 46 cast as an integral part of vaporizer 34, project upwardly into the combustion chamber which isset oi by one section of a chimney. This particular section 48 of the chimney has a number of perforations 5I! therein and is in telescoping relation with section 52, which is rigid with partition I6.

Vaporizer 34 is held in the operative position through the employment of a clevis 54 and bolt 56, arrangedA as shown in Fig. 1.

The position of perforations 24 in partition I4 is as illustrated, and the path wherein the same are located'should circumscribe section 48 of the chimney.

An annular plate 58 rests upon the top of partition I4 and has holes 60 therethrough, which may be brought into register with perorations 24, or which may be offset therefrom to provide air passages of predtermined size. These perforations and holes 24 and 60 respectively, communicate with air chamber I8 and allow the pas-` sageof preheated air from duct 22 into chimney 48 when the burner is in operation.

A defiector 62 carried by arms 64 is above the open upper end of the chimney, comprising sections 48 and 52. This deector is formed to direct products of combustion toward duct 22 and also toward the innersurface of the annular wall of case 6.

A door 66 in case 6 has a draft opening 68 therethrough that is governed by the conventional valve member 10 so that if more airis needed .to support combustion, it may be supplied. directly through perforations 50 from the openings in door 66.

The operation of an oil burner made in accordance with the present invention is obvious to one skilled in the art, and it is seen that when the burner is to be generated, valve 40 is opened and the hydrocarbons allowed to pass into the lower portion of pan 26 through the openings 12 that are positioned above the lowermost portion of vaporizer 34 sothat a small amount of oil may collect in the vaporizer. When a suiiicient amount of. oil is collected in tray 26, it is ignited by opening door 66. and raising section 48 of the chimney. When the oil remaining in vaporizer into gas by the applica- 14 located adjacent the top of vaporizer I4 where it is ignited and burned in the combustion chamber defined in part by section Il of the chimney.

Fins assist in the transfer of heat to the vaporizer 34 and in'normal operation,v the oil stove.

l 2,257,834 tion of heatj/'the said gas escapes through jets Air in support of combustion enters duct 22 v and passes in the direction of the arrows shown in the drawing, to a place within the chimney where combustion actually occurs. The passageV of this air in the paths of travel indicated, is advantageous in that no carbon deposits are permitted and the form of the ilameis such as to readily heatthe annular wall of case 8 as well as the duct 22.

The specific manner of constructing an oil burner embodying this invention may be greatly varied and details illustrated in the accompanying drawing are for purpose of exemplifying the way of making the preferred embodiment thereof and therefore, it is desired to be limited only by the scope of the appended claims.

Having thus described the invention. what is claimed as new and desired Letters Patent is:

1. In an oil burner of the character described a case provided with a ilue at the upper portion thereof; a perforated partition in the lower portion of the case to provide an air chamber inthe case below the partition; an air inlet duct extending through the case from the upper portion thereof to the air chamber; an annular vaporizer mounted on the partition and joined to a source of oil supply; a cylindrical, extending around the vaporizer thereabove to define a combustion chamber; and a perforated to be secured by the flue. said partition having a perforated plate thereon movable to and from a position where the perforations thereof are in register with the perforations of' said partition to alter the amoamt of air passing upwardly into the case from the air chamber. y
