regenerative lamps;and itconsists in the combination of a regenerative gas-lamp and a vapor-producer, so arrangedv that hydrocarbon vapors produced from petroleum or other oils or spirits may be employed in the lam p,either alone or with other gases, as hereinafter more fully appears.

I will now describe my invention, so that others skilled in the art may employ the same,

. the products ofcombustion pass.

reference being had tothe accompanying drawings, forming part of this specication, in Which- Figure lis a vertical sectional view ofa Siemens regenerative gaslamp having the vaporproducer attached. Fig. 2 is a horizontal sectional view of the vapor-producer on the line y y, Fig. 3; and Fig. Sis a vertical view of the same on the line .fr at, Fig. 2.

Like letters ot' reference indicate like parts wherever they occur.

ln the drawings, a represents the inlet airilue of the lamp, b the inlet gas-tine, and c c the outlet and regenerative flue through which These parts may be constructed in the ordinary manner and ofthe same materials as are now employed when the lamp is used in connection with coalgas.

Around the lower portion of the lampand attached thereto is a haring cup, f, the purpose of which is to prevent the products of combustion passing off from the vapor produced from entering the lamp through the air, inlet fiue a. The gas or vapor inlet pipe b of the lamp extends through and below the cup or detlector f. Secured to the end of this vapor-inlet pipe bis the supply-chamber g of the vapor-producer, the two pipes being united by a screwthread or other suitable joint. This vapor-producer is formed of suitable cast metal having an inlet or oil-suppl y pipe, h, which enters near the top of the casting and passes thence by two horizontal branch passages,z' ,around the vertical chamber g, where Serial No. 136,225. (No model.)

the two passages t' t' unite. Extending vertically downward from the points where the passages t t' branch from each other are the passages 7c 7c, which communicate with the horizout-al passage m, situate below the bottom of the vapor-chamber g, and which extends beyond the body ot' the vapor-producer inside of the annular iiange n. Extending from the bottoni ot' the producer through the end portions ofthe passage m in the ii'ange n are two screw-needles@ o, the points of which extend through small apertures p, extending from the passage m through the upper portion of the flange a, inclining at an angle toward the body of the producer. A similar and larger screw-needle, q, extends from the bottom of the producer vertically upward to the chamber g, intersecting the passage m, the needle-point entering the vapor-chamber g through an aperture,1,similar to the apertures p p. Extending Aupward around the producer from the annular iiange r at the top of the producer is a shield, s, inclosing that portion of the producer between the flanges, and having air-inlet openings s and exit-openings S2, for the products of combustion.

The screw-needles o q are provided with suitable handles, by means of which the apertures p p r may be opened or closed, so as to permit a regulated amount of oil or vapor to pass upward on the upper side of the tiange n, and the vapor to pass from the passage m into the chamber g.

The supply-pipe h is connected with a suitable reservoir of light hydrocarbon oil or other suitable liquid hydrocarbon, whether oil or spirits. y

Theoperation is as follows: The screw-needles o o being lowered inthe apertures ppthe oil passes from the passage m to the ange n., where it is ignited, and the tiame thereby produced striking against the sides of the body of the producer heats the same and converts the oil in the passages 'i i and m into vapor, a portion of which passes through the apertures 19 p and continues to support the anie above the ange n.. As soon as vapor is produced in the passagesz' i and m,the screwneedle q is lowered and the vapor passes from the passage m into the chamber g, into the inlet-tine a of the lamp, and thence through the burner-jets a', at the mouth of which the vapor or gas ICO unites withV the air which enters through the flue b, and, being ignited, the flame produced ascends around the porcelain cylinder c", and thence passes into the regenerative flue or heating-chamber c with the products of combustion, which are drawn thence through the chimney c. The flame and products of com- "bustion passing into the chamber c heat the walls of the same, and this heat is imparted to the currents of air and vapor as they pass through the flues a b, converting the vapor into dry or superheated hydrocarbon gas before it reaches the mouth of the burner. Outside ofthe body of the lamp is a jacket ofsheet metal, t, between which and the body of the lamp a current of air ascends,whieh prevents the overheating of the lamp, and also increases the supply of air. On top of this outer casing rests a cylinder of glass. which protects the ame from the action of the wind. At the base of the inlet-Hue b is a branch pipe, w. which communicates with the ue a, and by means of which non-carbonized hydrogen or water gas or carburested-hydrogen gas which is deficient in carbon may be employed in the lamp in connection with the hydrocarbon vapor produced in the manner described. Y

The advantages of my invention are, that the regenerative lamps can be used with or independently of a supply of coal-gas, and that the light produced from the combustion of the hydrocarbon vapor'is greatly intensified by the action of the regenerative lamp, and the unpleasant and injurious products Ofcombustion of hydrocarbon oil are removed by the action of the heat, which converts the vapor into gas.

It is common in vapor-burners to employ a mixing-chamber wherein the vapor is combined with air before being introduced into the burner. This chamber is omitted, however, by me in the Vapor-producer used in connection with the regenerative lamp, as it is preferable that the vapor be used in its pure state unmixed with air.

By means of the devices herein described the temperature of the vapor as it passes through vthe la'xfnpiis'brou'ght to a sufficient de-` greeof heatfCabout 900..Fahrenheit) to thoroughly disintegrate the vapor-globules and form a xed gas, which will not condenseinto a vapor or liquid when brought to its normal temperature, as I have proved by actual experiment.

Having thus described my invention, what I claim,an'd desire to secure by Letters Patent, 1s

1. The combination,in a regenerative lamp, ofagasaditi1ue,and exit-flue for the discharge of the waste products of combustion,arranged in proximity t0 the gasadit line, for the purpose of heating the same, and a vapor-producer communicating with the gas-adit flue, for the purpose ofvaporizing hydrocarbon liquid and discharging -i-ts vapor thereinto, so that the heat applied to said gasflue by the exit-flue may be of sufficient temperature to convert said vvapor into a fixed gas, substantially as described.

2. The combination of a regenerative lamp and a vapor-producer arranged so that the hydrocarbon-vapor shall pass directly from the producerinto the superheating-flue of the lamp, substantially as and for the purposes specified.

' 3.'A A regenerative lamp having a vapor-producer connected therewith, in combination with a shield situate between the vapor-producer and the inlet-opening of the air-flue of the lamp, substantially as and for the purposesspecified.

4. In a lamp or illuminator, the combination of a hydrocarbon-vapor producer or generator, a heating-chamber forsuperheati ng the vapor before it passes to the burner, anda burner, substantially as and for the purpose specified.

In testimony whereof I have hereunto set my hand this 24th day of June, A. D. 1884.
