2 Claims. (Cl. 15876) This invention relates to improvements in oil burner apparatus and is directed more particularly to apparatus adapted for use with boilers and heaters of varioustypes.

The principal object of the invention is to provide an oil burner apparatus ofthe conversion type that is constructed and arranged whereby the apparatus may be applied to various boilers, heaters and the like, but obviously may be a component part of a boiler, heater or the like.

According to special features of the invention, the apparatus is constructed and arranged so as to be compact in form and efficient in operation and its novel form and operation makes it possible to burn a relatively greater amount of fuel in a smaller combustion. chamber than is the practice with prior art apparatus thereby enhancing efficiency in operation.

Various novel objects and advantages of the invention and the novel features of construction and arrangement will be observed from the following description of the present preferred form of the invention with reference to the accompanying drawings, wherein:

Fig. 1 is a sectional plan view through the apparatus of the invention:

Fig. 2 is an elevational sectional view on the 'line 2-2 of Fig. 1; and

Fig. 3 is a perspective view of an air control member for the apparatus shown-in Figs. 1 and 2.

Referring now to the drawings more in detail, the invention will be more fully described but it will be understood that various changes and modifications may be made in the form of the apparatus to adapt it for various uses and conditions without departing from the spirit and scope of the invention.

An outer tube 2 is provided that is adapted for insertion in the combustion chamber of a boiler or the like and it has an end provided with a sloping annulus 4. Suitable means such as a flange on the tube 2. not shown, or other means.

W An end plate 8 is secured to a flange ID of the "outer tube 2 and an inner tube I2 is carried by a flange I I that is removably secured tothe plate 8. A tube I6 for fuel extends forwardly within the inner tube l2 and has a nozzle l8 of usual 2 delivered by the nozzle. The tube IE will be connected to a suitable fuel supply and the electrodes 20 will be connected to a source of energy.

The end of the tube l2 has an annular ring 22, to provide a central opening forwardlyof the nozzle Ill. Both tubes have restricted outlets with the outer end walls of the tubes inclined towards the outlets.

A housing 24 at a side of the outer tube 2 is connected thereto in such a way as to provide an air passageway 25 from the housing to said tube. An impeller 28 is located in the housing and is carried by a shaft 29 of a motor 30 secured to the housing; As the impeller is rotated by the motor. air is delivered to the outer and inner tubes through the passageway 25. The flow of air may be varied or controlled to obtain the desired results.v

Various means may be employed for that purpose but for illustrative purposes a tubular sleeve member 40 shown in Fig. 3 is oscillatable in the outer tube 2. A clamp screw 42 threaded in the sleeve may extend through a circumferential slot form thereon. Electrodes extend within the tube l2 and have end portions 20 suitablyrelated to the nozzle so as to provide ignition for the fuel M in the tube 2 to effect rotary movements of the sleeve 4!) and to secure said sleeve in adjusted positions in the tube. By moving the sleeve in one direction or the other the area of an inlet represented by 46 may be varied thereby to vary and control the flow of air into the tube 2. An outwardly extending scoop-like member 48 is carried by the inner tube I 2 adjacent an inlet 5|] therein.

By means of the construction, air is delivered to the tube 2 around the inner tube l2 and to the inner tube through inlet 58. The air is caused to rotate or swirl as it passes from the rear or inner to the forward or outer ends of the tubes. This is desirable as the flow of air whilst maintaining combustion is such as to cause air to be drawn outwardly and combustion to take place outside of and forwardly of the tube 2 thus protecting the nozzle and other parts and resulting in the most eflicient operation.

Air delivered to the tube 2 may be varied as desired by adjusting the sleeve 40 or some other means as may be provided but such air as is delivered passes into the tubes more or less tangentially so as to. accomplish the desired swirling or rotation of the air.

The invention may be embodied in other specific forms without departing from the essential characteristics thereof. Hence, the present embodiments are therefore to be considered in all respects merely as being illustrative and not as being restrictive, the scope of the invention being 3 indicated by the appended claims rather than by the foregoing description, and all modifications and variations that fall within the meaning and purview and range of equivalency of the appended claims are therefore intended to be embraced therein.

What it is desired to claim and secure by Let-- ters Patent of the United States is:

Oil burning apparatus comprising in combination, a housing and outer tube construction having a passageway extending from the housing and leading into the outer end of the tube tangentially thereof, an air impeller in said housing and means for rotating the same for directing air through said passageway into the outer tube, means closing the outer end of said outer tube, an inner tube within and disposed coaxially of the outer tube extending from the outer end thereof and having its inner end terminating inwardly of the inner end of said outer tube, means closing the outer end of said inner tube, the side walls of said inner tube being spaced from adjacent walls of the outer tube and providing a, main annular air space therebetween, separate members on the inner ends of said tubes and being spaced apart to provide an air space therebetween in communication with said main air space and provided with central restricted outlets, fuel delivering and ignition means in said inner tube adjacent the inner end thereof, said inner tube adjacent its outer end being provided with an air inlet opening, a sleeve within the outer tube at its outer end provided with an opening in a side thereof and adapted for movement circumferentially of the outer tube to position the opening thereof relative to the said passageway and thereby control the flow of air into the said main annular air space.

2. Oil burning apparatus comprising in combination, a housing and outer tube construction having a passageway extending from the housing and leading into the outer end of the tube tangentially thereof, an air impeller in said housing and means for rotating the same for directing air through said passageway into the outer tube, means closing the outer end of said outer tube, an inner tube within and disposed coaxially of the outer tube extending from the outer end thereof and having its inner end terminating inwardly of the inner end of said outer tube, means closing the outer end of said inner tube, the side walls of said inner tube being spaced from adjacent walls of the outer tube and providing a main annular air space therebetween, separate members on the inner ends of said tubes and being spaced apart to provide an air space therebetween in communication with said main air space and provided with central restricted outlets, fuel delivering and ignition means in said inner tube adjacent the inner end thereof, said inner tube adjacent its outer end being provided with an air inlet opening, a sleeve within the outer tube at'its outer end provided with an opening in a side thereof and adapted for movement circumferentially of the outer tube to position the opening thereof relative to the saidpassageway and thereby control the flow of air into the said main annular air space, the side walls of the inner tube diverging from a point intermediate the ends of said tube to the inner end thereof thereby restricting said annular air space at the inner ends of said tubes.
