HYDROCARBON-BU RN ER FOR FU RNACES.

SPECIFICATION forming part of Letters PatntNO. 401,431, dated April 16, 1889.

Application led October 10, 1888. Serial No. 287,753. (No model.)

To all whom it 71mg/ concern:

Be it known that we, GRAvEs GRIFFITH and THEODORE L. MILLER, of Blanchard, in the county of Page and State of Iowa, have invented a new and useful Improvement in Hydrocarbon-Burners for Furnaces, dac., of which the following is a specification.

This invention has in view to provide a burner for hydrocarbon oils, the., to utilize the saine as heating media in connection with furnaces, stoves, ctc., whereby are secured, among other things, security against liability to eX- plosion from accumulated or unescaped gas and complete control of the oil-supply and the amount of burning-surface is regulated, while the requisite amount of air is fed to the burning oil or fuel and the intensity of the iiame is increased or diminished.

. The construction, arrangement, and operation of parts will be now described with reference to accompanying drawings, in which- Figure l is a sectional elevation of our innproved burner for hydrocarbon oils or other liquid fuel, to utilize the same as heating Inedia in connection with furnaces, stoves, ctc. Fig. 2 is a plan view of the same, and Fig. 3 is an enlarged detached plan view of the burner. Fig. i is a sectional elevation of a stove in which our burner is shown arranged as proposed in practical use.

In carrying out our invention we provide a receptacle, A, of required construction for containing oil and water, being connected with a water tank or reservoir, B, and with an oil or hydrocarbon tank or reservoir, C, by pipes a and b, respectively. The pipe b connects at one end with the bottom oi the tank C, and at its other end with the bottom of the receptacle A, projecting into the same a short distance. The pipe a connects with the bottom of the tank B at one end, while its other end connects with the receptacle A a short distance below the upper edge of the latter, and is provided inside of said receptacle with a short turned-down portion, as at a', in order to enter the contained water or liquid and serve as a seal for that end, the purpose of which will appear further on. The pipes o and h are provided with cocks c c', respectively, while the cover b of the tank B, which is provided with a thumb-nut shaped or other The pan D is cylindric in its general con-v disk-like bottoni and a cir- 'he required height, provid- The pan D is tour, having a flat cular side wall of ing it with a shallow chamber.

disposed within and supported near thetop edge of the receptacle A, having projecting therefrom radial arms or projections d d, resting upon said edge of the receptacle and leaving a space between the burner and receptacle for the entrance of air below the pan, as 1ndicated by arrows d d The pan or burnerchamber is divided into a number or series of sub-chanibers,D D2 D3, which are adapted to successively overflow each other, beginning with the central one, its walls or sides being lower than the walls or sides of the burnerchamber, while the walls between the chainbers D2 and D3 are lower than the walls or sides of chamber D In each of these chambers is a series of air-tubes, e e., which open through the bottom of the burner-chamber and supply air admitted below the pan D to the contents of said sub-chambers. The upper ends of the air-tubes e e stand slightly above the upper edges of the separating-walls of the sub-chambers to prevent the entrance thereto of the contents of said chambers. To the under side of the pan D is applied a conical or bell-shaped chamber, E, which communicates with the burner-chamber through a hollow neck or tube, f, connecting with the central sub-chamber, D', and up through which rises or passes the oil from the chamberE into the said sub-chamber, as indicated by the arrow f In operation it will be seen that the tank or reservoir B, being filled with water and the cock c opened, the water will iiow therefrom through the pipe a and enter the receptacle A, water being supplied to the latter until the turned-down end a of said pipe is submerged, when its iiow will cease, the cover 1J being screwed down air-tight. The waterlevel is a suitable distance below the bottom of the pan D, and there maintained by the keeping of the tank B well supplied with water after once supplying the receptacle A, as above described, and permitting the cock IOO c to stand open. The oil or hydrocarbon is supplied to the receptacle A below the cha1nber E by 'properly adjusting or opening the cock c of the pipe b, whence it rises through the water into said chamber E, through the neck or tube f, and into the central sub-chamber, D', of the pan. The oil, the supply or feeding of which is constant and regulated by the proper adjustment of the cock c', is fed to said central sub-chamber, D and the oil in the latter chamber ignited, the air to support combustion being supplied and maintained through the air-tubes e e to the surface of the oil or fluid. The air here commingling with the gases given off by the burning oilor Iiuid will promote combustion and generate an intense heat. In case a greater amount of heat should be required, the cock c. of the oil-tank pipe b would be opened still wider,

and the oil or i'luid be fed to the central subchamber, D', until it overlowed into the next sub-chamber, D2.

Again, the heating capacity of the burner may be increased by still further supplying oil or fluid thereto, when the oil or fluid will overflow the chamber D2 and enter the subchamber D3.

flow or feeding of the fluid or oil, as aforesaid, the oil will flow from the central chamber to the other sub-chambers in a burning state, as is obvious, while the supply of air to promote combustion therein will be secured through the air-tubes thereof, the same as in the case of the central burner-chamber.

It will be observed that the oil or fluid being fed through water no danger is to be apprehended from an explosion, as would arise in case of the feeding of the same where it is liable to be heated orin the absence of a cooling agent, as furnished by its passage through water; also, as a further safeguard, the conical or bell-shaped chamber E collects the main body of the oil or iuid and conducts it to a prescribed point and concentrates, as also contracts, the area of its supply to the burner to a minimum surface, while no gas of any appreciable quantity will accumulate from what oil or iuid may escape from the conical or bell-shaped chamber and arise through the water, outside of the latter, to reach the bot. tom of the pan, from which it is also separated by an air-space between said bottom and the level of the water. The air-currents generated at this point would also take or carry off any such gas up through the air-tubes to the burning oil or fluid, whence it would be consumed. It will also be seen that no superin- The process of combustion being maintained or kept up during the overcumbent column of water is required to effect the feeding of the oil or 'Huid to the burner, as is practiced in the ordinary method of burning oil or other hydrocarbons.

The principle of our invention may also be applied to a safety-lamp with or without a wick.

I-Iaving thus fully described our invention,

what we claim, and desire to secure by Letters Patent, is-

l. The pan provided with a series of air# tubes and having a series of concentric rings of varyin g height, forming annular chambers, in which said air-conducting tubes are distributed, and means for supplying oil to the inner chamber, as shown and described.

2. The pan having a series of concentric rings forming annular chambers, which are of varying height, and a series of air-conducting tubes distributed in said chambers, their upper ends projecting above the top edges of the chambers in which they are respectively located, and means for supplying oil to the inner chamber of the series, as shown and described.

3. The combination, with the pan for receiving and holding oil and the oil and water tank A, above which said pan is located, of the bell'- lshaped chamber E, arranged in said tank and connected with the pan, as shown and described. 4. The combination of the pan having a series of concentric rings of varying height, forming annular chambers, the series of airtubes interspersed throughout said sub-chambers and opening through the bottom of the pan, and the conical or bell-shaped chamber depending from the bottom of the pan'and communicating therewith through a tube or neck, substantially as specified.

5. The combination, with the receptacle A and connecting oil-tank and water-tank, of the pan having a series of concentric rings of varying height, forming annular oil-chambers, and the conical or bell-shaped chamber depending from the bottom of the pan and communicating therewith, the pipes connecting said water and oil tanks together being provided with cocks, while the discharging end of the water-supply pipe is turned down to submerge it below the water-level in said receptacle, substantially as specified.
