OIL BURNER.

Application led February 9, 1923.

To all whom t may concern:

Be it known/that I, ARTHUR G. SLocUM, a citizen of the United States, residing at Ensign, in the county of Gray and State of Kansas, have invented certain new and use-- ful Improvements in Oil Burners, of which the following is a specification.

This invention relates to an oil burner and particularly to a construction embody` ing a vaporizing chamber heated by the burner for converting the liquid fuel into a gaseous state and delivering the same to the ignition openings. n

It has been customary in the prior art to provide vaporizing burners with superposed retorts heated thereby but under such conditions the liquid fuel is fed into direct contact with the walls of the retort and if said walls are not of sufficiently high temperature only a portion of the fuel is Vaporized and the remainder flows downward in a liquid form into the burner so as to materially decrease the efficiency thereof and the character of` flame secured.

Furthermore, in previous constructions the vaporization o-f the fuel to secure the proper feed to the burner has been entirely dependent upon the temperature of the re* tort and has lacked means for securing an even degree of feed to the burner and for producing this feed under such pressureas will secure a flame of the most efficient character.

The present invention removes the objections existing in prior constructions by providing the vaporizer or retort with a reservoir disposed to retain a body of liquid fuel which is vaporized by the heat of the burner and the gases therefrom pass downward through a heated passage to the burner openings, together with means for controlling the feed of the liquid fuel to said reservoir.

A further object Vof the invention is to provide an improved form of burner in which the Lignition orifice is normally closed so as to create a proper pressure of the gaseous fuel in the retort and burner to effect the most efficient form of fiame at the burner openings and automatically govern the flow of fuel therethrough.

Other and further objects and advantages of the invent-ion will be hereinafter set forth and the novel features thereof defined by the appended claims.

Serial No. 618,001.

In the drawing:

Figure 1 is a perspective of the burner.

Figure 2 thereof.

Lilie numerals refer to like parts in the several figures of the drawing.

The numeral 10 designates the burner member which may be of any desired size or configuration and is provided at its base with the usual priming pan or tray 11 for the initial heating of the burner and retort.

This burner is provided at its base with a chamber 12 which communicates with a series of openings 13 discharging into burner seats 14 depressed below the upper surface of the burner and provided with ball valves 15 which normally close the outlet from the openings 13 but are raised when the pressure of the gaseous fuel becomes suiiicient so as to secure a feed and flame of a spray character entirely surrounding the valve members, as distinguished from a jet flame produced by the usual orifice or opening. v

lThe burner is further provided with a central opening 16 into which a tubular feed passage or pipe 17 is threaded such pipe being in full communication with the chamber 12 at its lower end. Y

A vaporizing chamber vor retort 18k is secured at the upper portion of the feed pipe 17 by means of a threaded collar 19 at thek underside of the retort. The upper face'20 of this retortI is substantially horizontal to present a plane surface and the side walls 21 thereof are inclined inwardly. From the base of these walls the bottom 22 of the retort is inclined upward toward the collar 19 and is of a substantially conical character.v In the present instance it is shown as convex which provides a reservoir 23 at the base of the retort adapted at all times to contain a body of the liquid fuel which is in direct contact with the highly heated base 22. Any desired means may be provided to feed the liquid fuel to this reservoir a preferable form being a feed pipe 24 extending through the heated pipe 17 and deflected laterally at its i ipper end 25 to discharge downwardly at 26 into the reservoir. This liquid feed pipe may be supported by the burner and is here shown as passing through a collar 27 of the burner base and provided with a controlling valve 28 by which the feed of the liquid fuel to is an enlarged vertical section the reservoir may be governed and controlled to prevent an excess of liquid therein which would tend to escape into the burner.

In `the operation of the invention the burner is started by the usual preliminary heating from the priming pan and the vapors passing from the surface of the fuel in the reservoir feed downward into the chamber of the burner until sufficient pressure is secured to permit their escape about the ball valves at which time the burner itself is ignited and maintains the continued operation by highly heating the base of the retort and also the side walls thereof. The conical form of this base tends to retain the heatfrom the burner in contact therewith and also to permit the escaping` heat to contact with the side walls of the retort so as to secure the most eiiicient and extended area of hea-ting surface.

The construction herein presented contemplates the feeding of the fuel to the reservoir of the retort as distinguished from the direct flow against a heated wall thereof and thus secures a vaporization from the surface of the fuel. These gases in passing downward through the vapor feed pipe are superheated which tends to increase the pressure in the burner chamber and effect a mosteiicient form of spray at the ignition openings.

While the details of this invention have been specifically shown and described, still it is not confined thereto as changes and alterations may be made therein without departing from the spirit of the invention as defined by the appended claims.

What I claim is: A

l. An oil burner comprising a burner member, a vaporizer member having its lower wall inclined downwardly from a central opening to form a reservoir for liquid fuel of outwardly increasing depth and extended over the burner member to be heated thereby, a central vertical vapor passage extending downwardly from said opening to the burner, and a fuel feed pipe disposed in said passage and discharging at its upper end into said reservoir.

2. An oil burner comprising a burner member, a vapor feed conduit extending upward therefrom, a. vaporizing retort disposed over the discharge from said feed and provided with a substantially convex base forming a reservoir inclining downwardly from the center and increasing in depth outward from said conduit, and means for feeding liquid fuel to said reservoir through said vapor conduit.

3. An oil burner comprising a burner member having a chamber at its base, a vapor feed pipe extending upward from said chamber, a vaporizing retort mounted upon the upper end of said pipe and p rovided with inwardly inclined side walls merging into a convex base portion disposed to provide a fuel reservoir at the basev of the vaporizer, and a liquid feed pipe extending through said vapor feed and having a defiected upper end to discharge downwardly into said reservoir.

l An oil burner comprising a burner member provided with a chamber having discharge openings communicating with recesses in the upper face of the burner, ball valves disposed in said recesses to automatically close the discharge openings, and a vaporizing member arrangedto be heated by said burner and communicating with the chamber therein.

5. An oil burner comprising a burner member having a chamber at its base with ignition o riiices extending therefrom to seats in the upper face of said burner, ball members disposed in said seats to control said orifices, a vapor passage extending upward from said burner, a retort carried by said passage and having its base overhanging said burner, and means for feeding fuel to said retort.

6. An oil burner comprising a burner member having a chamber at its base with ignition orifices extending therefrom to seats y in the upper face of saidburner, ball mem-y bers disposed in said seats to control said orifices, `a vapor passage extending upward from said burner, a retort carried by said passage and having its base overhanging said burner, said retort having at its base a reservoir for liquid fuel, and a feed pipe within the vapor feed discharging into said reservoir.

In testimony whereof I affix my signature.
