To aZZ whom it may concern:

Be it known that I, FOREST A. RAY, of Boston, in the county ofSuifolk and State of Massachusetts,'have invented certain new and useful Improvements in Burners,of which the following is; a'specificatiou.

This invention relates to burners for use in lamps and other situations; and its object is to provide an intense heat with a minimum expenditure of fuel. i f

The invention also has for its object to provide certain improvements in the structure at dburners, as more ,fully hereinafter speci- The invention consists in the improved burner and the improved lamp hereinafter described and claimed.

Of the accompanying drawings, Figure 1 represents a side elevation of a lamp constructed in accordance with fmy invention.

1 Fig. 2 represents a vertical section thereof on an enlarged scale. Fig; 3 represents a section on the line 3 3 of Fig. 2. Fig. 4 represents a detail perspective view showing the construction of the burner-plugs.

The same reference characters indicate the same parts or features in all'the drawings Wherever they occur.

Referring to the drawings, 1 2 represent tubes or conduits forming a rectangular or substantially O-shaped frame surrounding the lamp and supported bya stem 3, consist-- ing of a gas-pipe connected with a source of illuminating-gas and continuous with the tube 2. Thetube l is partitioned off from the tube 2 and constitutes a water-leg, which is supplied with water under pressure through a pipe 4 from atank 5 The desired water pressure in the tube 1 may be supplied by maintaining an air-pressure in the tank 3 above the level of the water or by elevating the tank sufficiently to give a gravity-prev sure of the desired amount, or the water-pres sure may be obtained in any other suitable manner,-as by connecting the pipe 4: with a street-supply. It is desirable that the pressure in the pipe 1 should be kept substan-j tially uniform. 6 is a cylindrical casing supported by the frame 1 2 and supporting above it alarger burners 9 9.

Serial No. 69,891. (No model.)

cylindrical casing 7, which'in turn supports above it a burner-casing 8, having a pair of ,the bottom of the casing 7 and is provided at its lower end with a flaring mouth or orifice 11. At the upper end of the casing 7 is an annular series of perforations 12 12, constituting air-inlets and controlled bya valve in the form of a ring 13, provided with perforations 1414:, which may he slid into and out of register with the perforations 12 by rotating said ring. The interior of the casing 6 connects with the gas-pipe 2 and with the interior of casing 7 through a series of perforations 15 15, formed in a partition separating the two casings.

37 is a wrapping of sound-deadeningmaterial surrounding the mixing-tube 10.

16 is a steam-nozzle surrounded by the gasperforations 15 15 and directed into the mouth of 'the mixing-tube 10, said nozzle having a minute outlet or perforation 17. A needle 18, mounted upon a stem 19, which slides through a stufling-box 20 and is provided with a handle or knob 21 at its lower end, is guided in alinement with the steam-outlet 17 and is adapted to be moved into said outlet to clean the latter whenever this becomes necessary.

' 22 represents a substantially U-shaped water vaporizer or steam-generator, forming an ,arch over the burners,- with its top and side 1 legs in heating relation thereto and connected lat one end bya union or coupling 23with the water-pipe land at the other end by a union "or cou'plin'g-24s-witha small pipe 25, which is jointed to the steam-nozzle 16.

A valve 26 in the water-pipe 1 controls the supply of water ,to the vaporizer 22, and avalve 27 in the gas- .pipe 2 controls the supply of gas to the gas chamber or casing 6. The vaporizer 2.2 consists of an outer metallic tube or casing filled with granular carbon 28, which isretainedin the tube by means of removableperforate nature is not destroyed or injured by the action of heat on the vaporizer, and it has the ;plugs 29 29, placed in theends of the-tube. i The granular carbon 28 being of a refractory IOO effect of greatly increasing the interior heating-surface of said vaporizer, so as to secure a rapid vaporization of the water therein.

The water is fed directly and continuously to sure of the water column. In the latter partof the length'of the vaporizer the steam generated in the first part of its length becomes highly superheated and passes through the burner without condensation. The granular carbon besides acting as heating-surface also acts as a filter, both for the water and for the steam generated therefrom, with the result that a very pure supply of steam is furnished to the nozzle 16.

Above each of the burners 9 9 I have shown a refractory mantle 30, which becomes heated and gives a high illumination from the effect of the impingement of the flame from the burner thereon.

The jet of steam issuing with considerable force from the nozzle 16 into the mixing-tube 1O draws the air which enters chamber 6 through inlets 12 12 into the mixing-tube by an ejector action and produces an intimate mixture of the air and steam with the gas issuing into said tube through the perforations 15 15. The mixture of the fluids is further promoted in passing through the burnerorifices. These orifices are filled by perforate plugs 31 31, held in place by flanged rings 32 32, which slip over the mouths of the burnertubes 33 33. The plugs are made by rolling or wrapping a strip 34 of wire-gauze whose width is equal to the length of the plug into the form of a circular coil or roll, the construction being represented in Fig. 4, in which it is seen that the convolutions are in mutual contact. The eifect of a burner-plug or outlet of this nature is to interpose a considerable resistance in the path of the fluids, securing their intimate mixture and overcoming the noise or whistling which is characteristic of many burners which are run under a heavy pressureof vapors or gases. The plugs 29 29 are of a similar construction to the plugs 31.

My improved burner gives a flame of very high temperature, due to the forcing of the fluids under pressure, their intimate mixture, and their complete combustion within a short distance of the burner-orifices. The steam becomes decomposed by the heat of the flame and burns with the air and gas. This decommyself to the details of construction herein set forth nor to any particular number of burners, for it is obvious that a greater or less numberthan two may be employed with a corresponding number of refractory mantles when the invention is applied to lighting puroses.

p I can use my apparatus as an oil-burner by substituting hydrocarbon oil for water in the vaporizer 22, in which event the gas'supply furnished through pipe 2 may be discontinued, except as a convenient means for a preliminary heating of the vaporizer. The gas thus used readily entrains its own air-supply in passing into the mixing-tube 10 before the oil is turned on. It will also be noted that the gas-outlets 15 and jet-outlet 17 are arranged parallel to each other, and the air-supply for both of these fuel-jets is derived from a common source-namely, the casing 7, fed by the air-inlets 12. This construction avoids any possibility of an escape of oil-vapor into the atmosphere through auxiliary air-inlets or'otherwise when the vapor-jet is first turned on after the preliminary heating, as is observed in some prior forms of apparatus.

It will be seen that the nozzle-piece 16, containing the middle orifice 17 and surrounding or outlying orifices 15, abuts or overlies the gas-casing 6 and is traversed by the sleeve 40, which forms a bearing for the cleaningneedle 18, said sleeve having a screw-threaded connection at 41 with the nozzle-piece 16 and a shoulder 42 at its lower end abutting the lower end of the casing 6, whereby the parts are removably held in assembly. The vaporizer outlet-tube 3 is carried laterally into the chambered portion of nozzle-piece 16, and the cleaning-needle 18 traverses said chambered por-outlet 17 of sediment none of the sediment in the vaporizing-tube is disturbed. The cleaning-needle is made parallel-sided, as shown, and is mounted so as to slide freely in a longitudinal direction. When cleaning is required, the needle can be projected into the orifice 17 and withdrawn without interrupting the operation of the lamp, for by reason of the parallel sides of the needle it does not tightly close the orifice, as a conical needle-valve would, and by reason of its sliding mounting it can be so quickly projected and withdrawn as to obstruct the orifice 17 only for a brief instant.

I claim- 1. A burner-tube having an outlet occupied by a roll or volute of wire-gauze with its convolutions in mutual contact, means for supplying combustible fluid to said burner-tube, means for supplying air to the burner-tube to mix with such combustible fluid, and means for supplying an additional fluid to said burner-tube.

2. In a burner apparatus, the combination of a Bunsen burner having a plurality of orifices for supplying said burner with different IIO fluids, a substantially O-shaped supportingframe for said burner surrounding the latter and composed of separate branch conduits connected with the respective orifices,a source of water-supply connected with one of said conduits, and means for supplying a combustible fluid through the other conduit, a portion of the water-supply conduit having a granular filling confined therein.

3. In a burner apparatus, the combination of a burner having an air-casing 7, a gas-casing 6 jointed thereto, a nozzle structure 16 abutting said gas-casing and having a middle orifice and an independent series of orifices
