OIL-BURNER.

Specification of Letters Patent. Patented Dec. 10, 1918.

Application filed May 16, 1918. Serial No. 235,017.

To all whom it may concern Be it known that I, FLAvE J. Scorr, a citizen of the United States, residing at Marshalltown, in the county of Marshall and State of Iowa, have invented certain new and useful Improvements in Oil-Burners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to that class of oil burners which convert the oil into vapor and mix it with air before combustion takes place, and the object is to provide an extremely simple and inexpensive, yet a highly eflicient and desirable burner of this class which may be used for numerouspurposes.

With the foregoinggeneral object in view, the invention resides in the novel features of construction and unique combinations of parts to be hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying drawing which forms a part of this specification and in which:

Figure 1 is a side elevation of the burner;

Fig. 2 is a vertical section thereof; and

Figs. 3 and 4: are horizontal sections on the planes of the lines 33 and l-Aresped tively of Fig. 2.

In the drawing above briefly described, the numeral 1 designates a horizontally disposed ring formed of piping and serving to vaporize the fuel, said ring having a fuel supply pipe 2 which rises vertically thereto, and a fuel outlet pipe 3 which depends from the ring, the lower end of said pipe 3 being bent laterally and upwardly at 4 and having a fuel discharge nozzle 5 disposed centrally under the ring 1. A pilot pan 6 is suspended from the lateral portion a of the pipe 3 for initially heating said pipe so that the fuel passing therethrough will be sufliciently vaporized to burn and heat the ring -1. v

Extending diametrically across and secured at its ends to the ring 1, is a horizontal bridge bar 7 upon which the top 80f a cylindrical casing 9 rests at its center. The casing 9 is open at its lower end and the top 8 of said casing is depressed, to form a spreader, being of substantially concavoconvex formation as shown clearly in Fig. 2. Around itsperipheral'portion, the top 8 is formed with perforations 11 and others 12 are located in the wall of the casing immethe ring 1, down the pipe 3, and is -will be highly efiicient and desirable.

diately beneath the plane of the ring 1. A single central fastener 13 is provided for securing the casing to the bridge bar 7 said fastener passing through said bar and through the center of the top 8 as shown. This arrangement is not only simple and inexpensive, but when the burner is used in a furnace for instance, so that only one side thereof is accessible for cleaning, the entire casing may be turned upon the fastener 13 so' that the openings 11 and 12 may be cleaned throughout the circumference of the casing. It is also worthy of note that the depressed top 8'forms a spreader and at the same time coacts with the bridge bar in supporting the entire casing.

In operation,the burner may be "installed wherever required and the oil is supplied by means of the pipe 2, this oil flowing throigh 1scharged from the-nozzle 5 in the form of vapor. This pipe 3 is initially heated by'the priming pan 6. The vapor rising from the nozzle 5 into the casing 9 mixes with air andforms a highly combustible fuel which readily burns and produces intense heat. Considerable burning of the fuel takes place in the casing 9 and thus heats the ring 1 so that the oil passing therethrough will be vaporized without using the pan 6 except when initiallyv lighting the device. The top 8 spreads the burning gases and forces them in jets through the openings Hand 12 as will be readily understood from Fig; 2.

From the foregoing, taken in connection with the accompanying drawing, it will be obvious that although my invention is of extremely simple and inexpensive nature, it Since probably the best results are obtained from the exact construction shown and described, it is preferably followed, but within the scope of the invention as claimed. considerable latitude is allowed for making such minor changes as occasion may dictate.

I claim;

An oil burner comprising an oil vaporizing ring disposed horizontally, an oil supply pipe rising vertically to said ring, an outlet pipe depending from said ring, and a fuel discharge nozzle below said ring to which said outlet pipe extends; together with a horizontal bridge bar extending diametrically across and secured to said ring, a casing in which said ring and said pipes are located, said casing being open at its lower end and having adepressed substantialiy concav0convex top resting at its center-on said bridge bar to support-the casing and 1 peripheral portion of said casing havstantially as which the burningthe Spreader and a, central'fastener connecti-ng said casing top to said bridge bar, suba-nd for the purposes set forth. 10

In. testimony whereof I have hereunto set my hand.

FLAVE J. SCOTT.
