This gas, beingvlighterlthan oil', attemptsto rise to the:top,-but it is impossible forthe oil' and gas to separate while flowingiaround the coils. This mixture of .o-il with the vapor causes a lowering o ii ternperature to such an extent that complete combustion is impossible and depositi'on of carbon results In the vpresent invention, the oil passes into a retortwhich is maintained at a very hightemperature and is immediately vapor-' ized. A uniform temperature is maintained 40 throughout the retort and mixture of oil and vapor is prevented as the oil is vaporized as soon as it passes into the retort. I This gives a vapor which burns Without deposi tion of carbon. The burner construction above described is shown but not claimed in my co-pending application, and forms the subject matter of the present application.

An object of the invention is-the provision of an oilburner in which the oil will be completely and properly vaporized before] being admitted to the burner A further object is the provisionv of a burner casing in which the vaporizing retort ted lines 14, in Figure 1 of the drawings.

The provision of a retort arranged entirely at the front of the casing, forwardly of the point Where the flame strikes the Walls of the cas- ,ing insures a temperature Within the-retort sufficiently high to immediately vaporize the oil; vThis provides a fuel Whichwill burn properly without deposition of carbon.

' It will be apparent that the vaporizing chamber or retort ishighly, heated by the flame'from the burner and theoil is vaporized as soon as it' .reaches ,the retort. There is no oil present at any time ithin the retort and mixture of oil -and vapor is pre-" vented. JIn addition, the oil enters at the bottom and the vapor is removed at the topq so I as by pressure. Iheretort is;pr0,v ided,Wil h (I i The vapor being lighter than the oil, flows freely to the top and there is no tendency to carry oil into the burner mixed with the vapor. A substantially uniform temperacasing and disposed forwardly of the point where the flame strikes the walls provides a burner by means of which a higher temperature may be obtained than in a construction where the retort extends rearwardly of the point where the flame strikes the walls.

As stated, the deposition of carbon is reduced to a minimum and the length of time that a burner may be operated without stopping to remove carbon from the burner casing is materially increased.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resortedto without departing from the spirit of my invention or the scope of the subjoined claims. i A

Having thus described my invention, I claim:

v 1. A burner comprising a casing forming a combustion chamber, a nozzle mounted adjacent the rear of said casing, a vaporizing retort surrounding said casing and terminating at substantially the point where the flame from said nozzle strikes the wall of said casing, a feed pipe connected to said retort exteriorly of said casing, and a pipe connecting said retort and said nozzle, said pipe extending exteriorly of said casing.

2. A burner comprising a casing forming nozzle against the wall of the a combustion chamber, the rear of said casing being open for the introduction of air, the forward end of said casing being formed of'double walls to provide a vaporizing retort, a feed pipe connected to said retort exteriorly of said casing, a. nozzle mounted in the rear of said combustion chamber,- a pipe connecting said retort to said nozzle, said pipe extending exteriorly of said casing, and means for directing the flame from said combustion chamber adjacent said retort.

3. A burner comprising a casing forming a combustion chamber, the rear end of said casing being open, the forward end of said casing being reduced and provided with spaced walls to form a vaporizing retort, a

feed pipe connected to said retort exteriorly of said casing, a nozzle arranged adjacent the rear of said combustion chamber, and a pipe connecting said retort and said nozzle,

said pipe extending exteriorly of said ca'sing, said retort terminating at substantially the point where the flame fromsaid nozzle strikes the wall of the combustion chamber.

4. A burner comprising a casing forming a combustion chamber, a nozzle arranged adjacent the rear of said combustion cham: ber, the 'walls of said casing converging vertically forwardly of said nozzle anddiverging horizontally to provide a broad outlet of restricted height, a vaporizing retort surrounding the forwardend of said casing, said retort terminating at substantially the point where the flame from said nozzle strikes the wall of the combustion chamber, means. for conveying fuel to said retort, and means for conveying vaporized fuel from said retort to said nozzle.

In testimony whereof I aflix my signature in presence of two witnesses.
