OIL BURNER Filed June 8, 1938 L80 la -OOOOOO '0 agave Ji in 6 ATTOR N EYS Patented Apr. 18, 1939 UNITED STATES PATENT OFFICE 1 Claim.

This invention relates to oil burners and has for an object to provide an oil burner in which two separate and distinct sets or pairs of horizontal air drafts enter the burner at different levels and at right angles to each other to promote a more intense flame with less fuel con sumption than conventional burners having a vertical center draft.

' A further object is to provide a burner of this type which will be formed of a few strong simple and durable parts, which will be inexpensive to manufacture, and which will not easily get out of order.

With the above and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter fully described and claimed, it being understood that various modifications may be resorted to within the scope of the appended claim without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawing forming part of this specification,

Figure 1 is a plan view of an oil burner constructed in accordance with the invention.

Figure 2 is a cross sectional view of a burner taken on the line 22 of Figure 1.

Figure 3 is a cross sectional view of the burner taken on the line 33 of Figure 2.

Figure 4 is a cross sectional view of the burner taken on the line 4-4 of Figure 3.

Referring now to the drawing in which like characters of reference designate similar parts in the various views, In designates the cylindrical body of the burner the same having a shallow inverted cone-shaped bottom II. The bottom of the body has attached. thereto an axially disposed depending tube l2. A flanged bushing I3 is threadedly engaged with an annular collar 14 which projects from the inner surface of the tube. The body is provided at the top with a flange I5. A tube I6 is secured at the lower end in the bushing l3 and extends upwardly in the body to a height slightly above the bottom. ll of the body. A fuel pipe I! enters the body tube l2 and directs the fuel into the space between the body tube and the central tube IS.

The body I is provided with preferably three rows of radially disposed openings 3 located above the median diameter of the body. These openings admit an air draft horizontally into the body.

The air draft is divided and directed by baflles each comprising a vertical wall I9 extending transversely of the body, and an inclined wall 20 at the top of the vertical wall. The inclined wall extends from just below the draft openings l8 to the top of the body.

The vertical walls l9- of the baflles are spaced a predetermined distance apart by spacing bars 2| which extend across the bottom of the walls near the ends thereof and are secured to the bottom H of the body by vertically disposed brackets 22 which rise from the bottom ll of the body. The vertical walls of the baflies form a 1D rectangular space extending across the body below the draft openings I8. The inclined walls of the baffles divide the draft openings into four sections or divisions, two of which admit air from opposite sides of the burner underneath 15 the baffles at one level while the other two admit air from opposite sides of the burner above the baflles at a higher level, as best shown in Figure 3. The opposing drafts which enter the burner above the baflies are disposed at right angles to the 0 opposing drafts which enter the burner below the baffles.

A substantially Y-shaped baflie 23 is interposed between the vertical walls l9 and is secured to and extends transversely to the walls at the 25 center thereof, as best shown in Figures 2 and 4. The bafile is secured to the center tube I6 through the medium of a tongue 24, best shown in Figure 3. The top of the center tube l6 extends to the plane of the lower edges of the vertical 3 walls l9 which latter are spaced above the bottom l l of the body Ill through the medium of the brackets 22.

The Y-shaped bafiie 23 provides the rectangular space formed by the vertical walls l9 of the baffle carried by the body, into two equal spaces, and the curved branches of the Y-shaped baffle effect a gradual reduction of area of the spaces as the branches approach the top of the vertical Walls '9. 40

In operation fuel enters the generating space between the tubes l2 and i6 through the pipe ll.

In this space the fuel is vaporized and ignited. It is then caught between the draft streams entering underneath the vertical walls IQ of the baiile carried bythe body. As the ignited fuel passes up between said vertical walls it is divided by the Y-shaped baflle 23 and the branches of the Y-shaped balfle force it out against the draft streams which enter the burner through the draft openings I8 above the inclined walls 20 of the baffle carried by the body In. This top draft forces the two flames together above the Y- shaped ballle and spreads out the fiame in a single fan shaped flame of great intensity.

The baiile walls l9 and 20 are cooled and kept from burning by the draft rising from beneath the vertical walls IS. The Y-shaped battle is cooled and kept from burning by the draft entering the center tube "5.

From the above description it is thought that the construction and operation of the invention will be fully understood without further explanation.

What is claimed is:

An oil burner comprising a cylindrical body, a tube depending from the body, a bushing in the tube, a tube disposed axially in the first named tube and open at both ends, a fuel pipe entering the first named tube, a pair of verti. cally disposed spaced baflle walls in the body, inclined baflle walls rising from the topof the vertical bafile walls and extending to the inner surface of the body, there being a plurality of rows of draft openings arranged in the body above the top of the vertical baflle walls, said vertical bafile walls being spaced from the bottom of the body, said inclined bafile walls dividing the draft openings into four sections two of which admit air from opposite sides of the body underneath the inclined baflle walls and underneath the vertical baflie walls while the other two admit air from opposite sides of the body above the inclined bafile walls to impinge against the draft rising between the vertical baffle walls at a right angle and form a fan shaped flame, and a bafile disposed between and connecting said vertical bafile walls for spreading flame outwardly toward the ends of the vertical bafile walls.
