Having described my invention, reference should now be had to the claims which follow for determining the scope thereof.

I claim:

1. An oil burner for use in conjunction with a furnace comprising an elongated horizontally arranged tubular element adapted to be positioned within the furnace, said tubular element having a series of horizontally spaced apertures through which air is laterally discharged, a blower joined to said element for delivering air thereinto, an elongated horizontal trough arranged in parallel horizontally spaced relation to said tubular element opposite said apertures, means for supplying oil to said trough, said trough being partially cut away along one of its longitudinal side walls whereby the side wall remote mates from said tubular element is higher than the side wall closer to said tubular element, said apertures being horizontally directed with some of them arranged below the level of the outer edge of said trough, whereby streams of air from said apertures discharge transversely over said adjacent side wall and some of' said streams of air engage the remote side wall thereof for deflection towards the fuel in said trough and to produce a whirling and turbulent flow of air relative to said trough.

2. An oil burner for use in conjunction with a furnace comprising an elongated horizontally arranged tubular element adapted to be positioned within the furnace, said tubular element having a series of horizontally spaced apertures through which air is laterally discharged, a blower joined to said element for delivering air thereinto, an elongated horizontal trough arranged in parallel horizontally spaced relation to said tubular element opposite said apertures, means for supplying oil to said trough, said trough being partially cut away along one of its longitudinal side walls whereby the side wall remote from said tubular element is higher than the side wall closer to said tubular element, said apertures being horizontally directed with some of them arranged below the level of the outer edge of said trough, whereby streams of air from said apertures discharge transversely over said adjacent wall and some of said streams of air engage the remote side wall thereof for deflection towards the fuel in said trough and to produce a whirling and turbulent flow of air relative to said trough, a series of heat retaining metal elements positioned in said trough in spaced relation, and oil absorbent means positioned in said trough about said metal elements.

3. An oil burner for use in conjunction with a furnace comprising a tubular element adapted to be positioned within the furnace, said tubular element having in a side wall thereof a series of horizontally spaced apertures through which air is laterally discharged, a blower joined to said element for delivering air thereinto, an oil receiving annular trough surrounding said element with the inneredge of the trough adjacent said tubular element being lower than the outer edge of said trough, said apertures being horizontally directed with some of them arranged below the level ofthe outer edge of said trough whereby 4 the air from said apertures discharges transversely over the adjacent side wall of said trough and operatively engages the remote side wall thereof for deflection towards the fuel in said trough to produce a whirling and turbulent flow of air relative to said trough and the fuel therein.

4. An oil burner for use in conjunction with a furnace comprising a tubular element adapted to be positioned within the furnace, said tubular element having in a side wall thereof a series of horizontally spaced apertures through which air' is laterally discharged, a blower joined to said element for delivering air thereinto, an oil receiving annular trough surrounding said element with the inner edge of the trough adjacent saidtubular element being lower than the outer edge of said trough, said apertures being horizontally directed and arranged below the level of theouter edge of said trough whereby the air from said apertures discharges transversely over the adjacent side wall of said trough and operatively engages the remote side wall thereof for deflection towards the fuel in said trough to produce a whirling and turbulent flow of air relative to said trough and the fuel therein, said tubular element having a second series of horizontally spaced horizontally directed apertures arranged above said first series of apertures, said second series of apertures being arranged above said outer edge of said trough whereby streams of air pass over the trough laterally picking up burning gases therefrom and forming the main flame of combustion which is carried outwardly and laterally of said trough.

5. An oil burner comprising a horizontal trough, means for supplying 'oil thereinto, a tubular member spaced horizontally from said trough and having in a side wall thereof horizontally spaced apertures facing said trough, a blower joined to said tubular member for causing a lateral flow of air through said apertures into and across said trough, the edge of the trough adjacent said tubular member being below the plane of the outer edge of said trough, said apertures being horizontally directed with some of them arranged below the level of the outer edge of said trough whereby streams of air discharging from said tubular member are deflected by said outer edge of said trough to contact the surface of the oil in said trough, some of said apertures in said tubular member being so arranged that a plurality of streams of air will project across the outer edge of said trough carrying therewith a portion of the burning gases from within said trough thus forming a main flame of combustion laterally of said trough. V

6. An oil burner as set out in claim 5, said tubular member being cone shaped, and said trough being annular and surrounding said tubular member. 3
