OIL-BURNER.

sPEcIFIGATIoN forming para ofnetrs Patent No. 735,292, dated August 4, 1903-.

Application led May 17, 1 902. Serial No. 107,785. (No model.)

Be it known that I, ELI POLLAK, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Penn- Sylvania, have invented a new and useful Wickless Oil-Burner, of which the following is a specification.

This invention relates generally to lamps, and more particularly to a wickless hydrocarbon-'lamp ,and the object ofthe invention is to provide a simple and efficient lamp of this character which can be utilized in conconsists in the novel features of construction upon the burner.

of the burner, the retort-vaporizer, and theV Fig, 3 is a vertical. sectional view taken through the reservoirV and burner, the retort-vaporizer being shown and` combination, all-of which willbe fully described hereinafter and pointed out in the claims.

In the drawings forming part of this specication, Figure l is a perspective `view of a lamp constructed in `accordance with my invention, the chimney and mantle being shown Fig` 2 is a top `plan View air mixer or commingler.

reservoir A, which may be of any suitable or desirable pattern and is provided with an air-inlet tube A', to which any suitable form of air-forcing apparat-usmay be connected.A

B indicates a pipe `which extends into the reservoir to a point adjacent to the bottom, the upper end of said pipe being connected to the coupling B', in which operates a needle-valve B2 for the purpose of controlling `5o the flow of hydrocarbon from the pipe B to the pipe C, which is also connected to the secured by means of a ring or collar I-I'.

Eig. 5 isA In carrying out my invention I employ a coupling B'and which is connected at its up- `per end to a retort D, `which is essentially in the form of-a-drum. A dash-pan E is provided beneath this retort, saidy pan being preferably supported by means of a bracket connected to the pipe C.

The burner comprises an essentially cylindrical-shaped casing F, which is supported upon the standard F', extending upwardly from the center of the top of the reservoir;

The casing F is open at the side adjacent to the retort and is also open at theto p. A perforated metal plate G is secured Aupon the open end of the casing F adjacenttothe retort, said perforated plate being heldin place by means of the threaded collar G',and at the open top of the casing a wire screen H is The casing F is formed with a threaded neck F2, into which screws the pipe-section I,.the airmixer K being attached to the outer end of said pipe-section, said mixer being essentially in the form of a hemisphere and provided with a series of perforations K',through which the air can enter. A valve-casingL is connected to the outer end of the air-mixer K, and in which operates the needle-Valve L', by means ot' which the ow of vapor into the mixer and burner is regulated, said vapor being conducted from the retort D t0 thevalvecasing L by means of a pipe M. The casing F has a central threaded stud N projecting upwardly from the bottom thereof, and secured upon said stud is a solid metallic body O, the purpose of which is to cause a considerable circulation within the casing, thereby producing a complete commingling of the vapor and air before passing through the wire screen for combustion, and by producing this complete commingling of vapor andairl am enabled to provide almost perfect combustion, and thereby reduce smoke and smell to a minimum.

In operation the reservoir is filled with oil to any desired extent and a delinite amount of air compressed within the same. The needle-valve B2 is then partially opened, permitting a small quantity of hydrocarbon fluid to pass upwardly into the retort, and a small quantity of alcohol or other combustible fluid is ignited in the flash-pan E, there- ICO casing F, and while the vapor is so passing a definite quantity of air is being drawn in through the mixer and mixes with the vapor. The commingling vapor and air becomes thoroughly mixed in the casing F, and inasmuch as the Hash-pan is still burning a portion of the commingled air and vapor will be ignited at the perforatedplate G and will con-Y tinue to burn at that point, thereby continuing to heat the drum-shaped retort, and thereby complete the vaporization of the fluid. The major portion of the vapor will pass upwardly through the screen and burn above the said screen, the solid body O serving to cause a sufcient circulation prior to combustion to provide for a thorough commingling of the vapor and air.

pressure.

By the construction herein shown and described I produce a lamp in which hydrocarbon oils of every description are thoroughly vaporized. prior to being mixed with air, and the fluid so vaporized is thoroughly commingled with the air prior to combustion, thereby reducing smoke and smell incidental to combustion to a minimum.

In the drawings hereto annexed and forming part of this specification I have shown what I consider the best means for carrying out my invention; but I do not Wish to limit myself to the exact details of construction, as it is obvious that they may be changed or altered Without departing from the broad principles of my invention. It will also be understood that I do not limit myself to the exact construction and arrangement of drumretort, but may employ any suitable construction for carrying out the vaporization of the iiuid fuel.

Having thus fully described my invention,

The retort is provided with suitable valves to prevent back v what I claim as new, and desire to vsecure by Letters Patent, is- Y l. In a device of the kind described, the combination with a burner perforated on one side, of a retort arranged adjacent said perforated side, a metal body within the burner and projecting upward from the bottom of same, an air-mixer connected to the opposite side of the burner and a pipe leading around the burner from the retort to the airmixer.

2. The combination with a cylindrical casing perforated on one side, an upwardly-'extending metal body centrally arranged on the bottom of the casing, of a gauze top, a retort adjacent the perforated side, an air-mixer chamber on the opposite side of the casing,ra pipe exterior of the casing connecting the retort and mixing-chamber, and a valve adapted to regulate the passage of vapor to the mixingchamber.

3. The combination with a reservoir, of a threaded socket on the top of the reservoir, an upwardly-open, cylindrical burner-casing having iianged openings on opposite sides, an integral projection extending downward from-the bottom of the casing, and having a downwardly-open, threaded socket therein, a standard threaded into the said sockets and adapted to support the casing, a pipe secured in one of the side openings of the casing, a mixing-chamber carried` by said pipe, a perforated plate secured in the openings in the opposite side of the casing, a gauze disk over the top of the casing, a flanged ring secured around the top of Athe casing and adapted to retain the gauze in position, a retort adjacent the perforated plate, means for feeding oil to the retort and burner-casing, and an upwardly-projecting metal body arranged within the casing.

ELI POLLAK.
