Application filed April 13, 1920. Serial No. 373,465.

To all whom z'tmay concern:

Be it known that I, Brennan N. Monrms,

a citizen of the United States, residing at' new and useful Improvements in ()iLGas' Generators and Burners, of which the following is a specification.

This invention relates to an oil-gas maker and burner and particularly pertains to that type of hydrocarbon burners embodying a retort and an arched conduit extending over the retort and connected thereto and having a burneropening arranged to direct flames against theretort. In burners of this type, oil-fuel, such as kerosene or other hydrocarbons is fed to. the retort preferably un der air pressure, and is converted into com.- bustible vapors by heating the retort, the vapors being delivered from the burner orifice and there ignitedto form flames whlch are directed downwardl a ainst the to of the retort with consi erahle force. he flames are spread by the top of the retort and are directed against the upwardly extending portion of the conduit ordinarily with such force and heat as to injure the walls of the retort at the point of impin ement of the flames. An object of this invention is to provide means for protecting the conduit against the destructive action of the flames so as to render the burner more durable. Another object is to provide a construction in the retort of burners of the above character whereby pulsation of the flame is obviated and a substantially uniform feed of the inflammable vapors insured.

Other objects will appear hereinafter.

The invention is illustrated in the accompanying drawings, in which:

Flgure 1 is a View of the device in vertical section as seen on the line 1-1 of Fig. 2. Fig. 2 is a view of the device as seen in side elevation.

Fig. 3 is a view in horizontal section as seen on the line 3-3 of Fig. 1.

Fig. 4 is a view in horizontal section as seen on the line 4-4 of Fig. 1.

More specifically 5 indicates the side wall of the retort which is bowl shaped and 6 designates the top wall thereof which is substantially flat. An arcuate or arched conduit 7 extends over the retort and is connected at its ends thereto; one end of the conduit opening to the interior of the re tort through the side Wall adjacent to the top thereof and the other end of the conduit communlcating through an aperture 8 with the interior of the retort adjacent to the bottom thereof. The inner wall portions of the conduit intersect with the'side wall of the retort and extend upwardly therefrom on dlametrlcally opposite sides of the top wall and normally would be subject to the destructive action top wall as will later appear. for protecting juredi by the H jections intersection of the conduit with the retort and extend inwardly from the inner wall portions of the conduit to points spaced a short distance. on the opposite sides of the center of the top wall;the adjacent ends of the projections being tapered as indicated at 10 to form flame spreading surfaces spaced from the conduit. An openig 11 is Asa means the conduit from being inames a palr of spaced proof flames spread'by the,

9 are formed on the top wall at the provided on the underside of the arched portion of the conduit which is fitted with a nozzle 12 having a burner orifice 14 which opens downwardly opposite the center of the top wall of the retort, and a cleanout opening 15 is provided in the top of the conduit opposite the burner opening.

Means are provided for delivering a hydrocarbon fuel to the retort which is normally closed by a plug 16 at a point near the bottom thereof, which-is here shown as embodying an opening 17 in the bottom of the retort in which a plug 18 is screwed; a feed tubal!) opening to the interior of the retort through the plug. The tube 19 leads from any suitable source of hydrocarbon supply, preferably being connected to a pressure tank by which the fuel may be delivered to the retort under air-pressure.

Extending into the retort from a point above the aperture 8 is a baffle 20 which is located on a plane beneaththe upper opening. leading into the conduit and terminat ing above the fuel intake. .This baflle is ordinarily submerged in the fuel within the retort'when the device is in operation and serves to prevent-vapors formed above the surface of the fuel in the retort from entering the lowermost end of the conduit and directs them solely through the uppermost end portion thereof. By this construction a uniform discharge of vapors from the nozzle is caused to take place and a non-pulsating or steady flame is produced,

it having been'found that where the baffle is omitted and vapors formed in the retort are permitted to pass into the lowermost end of the conduit an irregular or pulsating flame is produced, as is the case where the conduit does not open at both ends to the retort.

Extending beneath the retort is a base plate 21 the ends of which are connected to the retort through standards 22 and encompassing the retort is an asbestos wick 23 which rests on the base plate and passes between the retort and the standards.

In the operation of the invention initial generation of the vapors is effected by permitting a quantity of the fuel oil to flow out the nozzle on to the top' of the retort from whence it will flow over the sides of the retort on to the wick where it may be ignited; The heat resulting from burning the fuel on the Wick' will act to heat the walls of the retort so as to warm the oil content sufliciently to form inflammable vapors the generation of which will set up a pressure in the retort and cause a portion of the vapors to be discharged through the nozzle where they are ignited. The flames produced by the burning vapors will be directed downwardly a ainst the top of the retort and will strile thereagainst at a point centrally thereof and midway between the flame deflecting projections 9. The top of the retort will operate to spread the flames horizontally but they will be prevented from directly impinging on the conduit by the protecting projections which by reason of being formed of a thick body of metal will endure the destructive action of the flames. The walls of the retort will be heated by the flames directed on the top thereof to such extent as to maintain the generation of the vapors and continue operation of the burner.

I am aware that hydrocarbon burners have hertofore been constructed embodying a retort and an arched conduit connected thereto and I therefore do not claim this feature broadly; my invention consisting in the particular improvements in the construction of generators and burners of this type as set forth in the following claim.

I claim:

In an oil-gas maker and burner a retort, an arched conduit extending over said retort and having its ends connecting with the sides of the retort and opening thereto, a burner nozzle in the arched portion of said conduit opening opposite the center of the top wall of said retort and a pair of spaced projections on the top of the retort arranged on the opposite sides of the center thereof and projecting forward from the inner wall portions of the conduit at the point of intersection of the latter with. the retort, said projections being formed with inclined flame deflecting faces on their adjacent ends.

In testimony whereof I hereunto afiix my signature this 6th day of March, 1920.

RICHARD N. MORPHIS.
