OIL BURNER Filed Jan. 13, 1932 2 Sheets-Sheet 2 fii F 6 A flomey Patented Feb. 20, 1934 UNITED STATES PATENT OFFICE 5 Claims.

This invention relates to an oil burner which is intended particularly for use in stoves and furnaces, and has for some of its objects to provide,

. in a manner as hereinafter set forth, a burner of this character which will be simple in construction, strong, durable, and efficient and reliable in use, and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate like parts throughout the several views and wherein:-

Figure l is a view in side elevation of an oil burner constructed in accordance with the present invention.

Fig. 2 is a transverse vertical sectional view taken approximately on the line 2-2 of Fig. 1 looking in the direction of the arrows.

Fig. 3 is a vertical longitudinal sectional view taken approximately on the line 3-3'of Fig. '2 looking in the direction of the arrows.

Fig. 4 is a horizontal sectional view taken approximately on the line 4-4 of Fig. 3 looking in the direction of the arrows.

Fig. 5 is a bottom plan view of the hood.

Fig. 6 is a plan view of the bottom of the diffusing element.

Referring now to the drawings in detail, it will be seen that the embodiment of the invention illustrated comprises a firepot 1 of substantially rectangular form which is open at its top and is provided with series of air inlet openings 2 in its side walls the openings 2 being spaced above the bottom 3 of the firepot 1.

The bowl 1 is supported in vertically adjustable manner by the supporting stand generally designated 4 which comprises a base 5 having a standard in the form of a vertically disposed socket 6. The base 5 is equipped with leveling bolts '7 which are threaded vertically through the base. The socket 6 is adapted to receive slidably and adjustably a vertical bar 8 having a vertical slot 9 opening through its upper end, in which is accommodated a clamping bolt 10 projecting from one of the longitudinal walls of the firepot 1 through the medium of which the firepot maybe clamped in different positions of elevation on the bar 8.

A set screw 11 is threaded through the wall of the socket 6 so as to engage the bar 8 for securing it at different elevations in the socket.

Fuel supply pipes 12 leading from a suitable f el supply, have one end anchored in openings provided therefor in the bottom 3 or the firepot 1.

rtherein a substantially oval opening 22 in verti- Vertical tubes 13 of smaller diameter are threaded into the same ends of the pipes 12 and rise therefrom in the firepot 1 to a level below the air inlet holes 2. Threadedly mounted on the upper ends of the tubes 13 are spreader heads 14 over which Q the fuel oil flows by gravity in a film and is completely vaporized. An overflow pipe 15 extends into the firepot 1 through and above the bottom of said firepot as seen in Fig. 3.

Removably mounted by resting on the top of the firepot 1 is a gas diffusing plate 16 having integral lugs 17 depending from its lower side into the firepot l. for engagement with the side walls of the firepot for retaining the same against relative horizontal sliding movement. The difiusing plate 16 conforms substantially in plan to that of the firepot 1, and is provided with a centrally disposed, substantially oval opening 18. The lower side or the plate 16 has formed therein a series of grooves 19 radiating from the opening 18 76 to the outer edge of the plate.

Removably mounted by resting on the gas diffusing plate 16 is a heat intensifying hood 20 having a comparatively thick top 21 whichhas 0 8 cal alinement with the opening 18 in the plate 16.

Integral tapered vertical ribs 23 are formed on the inside of the side and end walls of said hood. The ribs 23 which are on the side walls of the hood 20, are provided with horizontal extensions 24 at their upper ends for resting upon the top of the plate 16 for supporting the hood on the spreader in vertically spaced relation thereto.

The ribs 23 being disposed between the plate 9 16 and theportion of the hood prevent horizontal movement of the hood relative to the spreader and maintain the walls of the hood spaced from the diffusing plate 16 and the flrepot 1. Through the medium of the supporting stand 4, the burner may be expeditiously mounted in position in a stove or furnace or in any other desired place where the burner may be used. The burner is adapted to use crude oil of low-grade and price. The fir'epot 1 is provided with the spaced vertical guides 25 on one longitudinal side between which the bar 8 is slidably adjustable.

The reference character A designates a conventional furnace or stove fire pot and B a filler plate which rests on the furnace or stove fire pot and on the top of the hood 20. It will be noted that the outer surface of the raised or thickened portion 21 of the top of the hood 20 is inclined, whereby to facilitate jamming of the filler plate 13 in positionbetween the stove firepot and the hood, thereby providing a substantially leakproof joint between said filler plate and hood, so that all air passing through the furnace or stove is required to pass through the burner.

When in operation air enters the firepot 1 thru the series of openings 2. Air also passes upwardly between the skirt of the hood and the firepot and through the grooves 19 in the underside of the top of the plate 16 and between the top of the plate 16 and the top of the hood. This is clearly indicated by the arrows in Figs. 2 and 3 of the drawings.

In this way, air is addedto the burning gasesoil burner constructed in accordance with the present invention will be readily understood, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the details of construction, and in the combination and arrangement of the several parts, may be resorted to which will fall within the scope of the invention as claimed.

While the burner illustrated in the drawings is shown of substantially rectangular plan, the same may be obviously of any other desired shape, such as square or circular.
