OIL BURNER Original Filed March- 7, 1955 Inventm Patented Apr. 13, 1937 PATENT OFFICE OIL BURNER ""William A. Dickinson, Burlington, 0010.

Application March 7, 1935,- Serial No. 9,878

Renewed July 7, 1936 2 Claims.

This invention relates to an oil burner, the general object of the invention being to provide means for producing the maximum amount of heat with the minimum amount of fuel by providing means for producing a great spread of the flame and means so mixing air with the oil vapors that more air and less oil is used than in burners as now constructed, with means for preheating and vaporizing the oil in the device.

This invention also consists in certain other features of construction and in the combination and arrangement of several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Fig. 1 is a longitudinal vertical sectional view thereof.

Fig. 2 is a top plan view with the cap and oil cup removed.

In the drawing, the numeral l indicates the body of the device which is of elongated form and made somewhat in the shape of a pan and this body is composed of the flame spreader-part A and the part B which forms a combustion chamher. The part B has the internal side walls substantially straight with the upper part of its end wall omitted to form an opening 3 which extends entirely across the end of the part B and from the bottom wall of this opening 3, the interior Wall of the end part slopes downwardlyand inwardly as shown at 4. At the junction of the parts A and B, vertically arranged and substantially wedge-shaped lugs or ribs 5 are formed, the rear wall of each of which curves inwardly and forwardly from a side wall of the part B and the front wall of each of which curves outwardly and forwardly to the side walls of the part A, the apex edge being substantially'vertical. The sides and ends of the part A slope upwardly and outwardly as shown at 6 with the upper portions of the internal wall of the end of said part A curving upwardly and forwardly as shown at 6. The side walls of the part A are formed with recesses 1 which extend downwardly from the upper edge of each side wall to a point adjacent the bottom of the part A and the bottom of the entire body I is formed with a longitudinally extending groove 8 having a concave surface. The 55 groove extends from the bottom of the sloping wall 4 to the bottom of the sloping wall 6. The shape of this groove is more clearly shown in Figs. 4 and 5.

A cap 9 has the lower edges of its side walls l0 fitting in grooves I I formed in the upper edges of the side walls of the part B and the rear end of the cap is open and the top is provided with the holes I2 and the front part of the cap is provided with a fiat extension 13 which rests on the rear portion of the part A and extends to the beginning of the recesses I. An oil supply pipe H extends through a hole in the bottom of the part B and has a cup l5 at its upper end which partly extends into the space formed by the cap.

Thus, it will be seen that when the oil in the cup I5 is ignited, the holes l2 permitting air to pass into the cap over the burner cup to keep the flame from burning therein, a draught will be set up so that air will flow into the space formed by the part B and the cap 9 through the opening formed by the spaces 3 and I0 and this air will cause the flame to flow forwardly into the part A. The sloping wall 4 prevents eddying of the down-draught for the air entering the device and as the flame strikes the parts 5, some of the flames will be deflected through the recesses I while other parts of the flame will strike the walls 6--6' which will direct the flame upwardly and forwardly so that the flame will have considerable width and length. These opposed vertical ribs tend to converge the mixture of oil vapors and air discharged from the chamber in order to facilitate a more thorough mixing. The sloping wall 4 prevents the air from whipping back and helps carry the oil vapors more easily through the combustion chamber and with this burner, no dampers are necessary. The fuel oil is vaporized and preheated as it flows upwardly through the pipe I4 .into the cup l5 and the wall 6-6 with the recesses 1 creates a fan-shaped flame.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

I claim:

1. A burner of the class described comprising an elongated pan-shaped body, a cap resting on the rear portion of the body and forming with said portion a chamber, the rear wall of said chamber having an opening in its top part for the admission of air, an oil supply pipe extending upwardly into the chamber and having a cup at its upper end, the side walls of the pan-shaped member in front of the cap having recesses therein, and substantially wedge-shaped vertically arranged opposed ribs extending inwardly from the side walls of the pan-shaped member at the front part of the chamber tending to converge the mixture of oil vapors and air dischargedfrom the chamber in order to facilitate a more thorough mixing.

2. A burner of the class described comprising an elongated substantially pan-shaped body, a

cap resting on the rear part of the member and forming therewith a chamber, the major part of the cap being raised to form a. hollow part which forms part of the chamberand thefront of the cap being fiat and resting on the side walls of the pan-shaped member, the upper rear portion of the chamber being open for the admission of air. the rear walls of the pan-shaped member sloping downwardly and forwardly from the opening, a pipe extending upwardly into the chamber, a cup at the upper end of the pipe, the side walls of the front portion of the pan-shaped member having recesses therein, the rear wallsof which terminate adjacent the front end of the cap, vertically arranged substantially wedge-shaped opposed ribs extending inwardly from the side walls of the pan-shaped member adjacent the front part of the chamber, the front wall of the panshaped member sloping upwardly and forwardly.

WILLIAM A. DICKINSON.
