To ctZZ whom it may ooit/cern:

Be it known that I,- CHARLES C. BRUCK'NER, a citizen of the United States, residing at the city of New York, in the county and State of New York, have invented an Improvement in Petroleum-Burners, of which the following is a specification.

.Burners for hydrocarbon liquids have been constructed in such a manner that the liquid is allowed t-o flow through a generator above the flame and the escape of gas into the flame has been regulated and the liquid has passed to the heated generator as rapidly as necessary and controlled by the escape of the gas into the flame. Lamps have also been constructed in which a mantle has been exposed to the action of a non-luminous llame, so 'as to become incandescent, and the nonluminous llame has been fed by a mixture of air and gas, the gas being generated by heat from the flame; but the generator has usually been placed above the flame and mantle, or at the side thereof, in a position to become sufficiently heated for the conversion of the petroleum or liquid hydrocarbon into a vapor. In the present invention I make use of a lilamentary tubular generator within the nonluminous flame and generally within the mantle, such filamentary tubular generator acting to furnish the heat necessary for converting the petroleum or other liquid hydrocarbon into a gaseous vapor and of a sufficiently high temperature to cause the same to burn without smoke and substantially non-luminous when mixed with air and burned at the base of the mantle.

In carrying out this invention the liquid hydrocarbon is supplied to one end of the lilamentary tubular generator and the escape ofA gas is regulated, preferably, at the discharge end and in issuing draws in and mixes with atmospheric air and passes on to the chamber of the non-luminous burner and is burned above such chamber, and the filamentary generator is Within the flame and preferably of copper or aluminium and so small that it does not interfere with the uniformity of combustion of the non-luminous iiame or with the luminosity of the incandescing mantle.

In the drawings, Figure l is an elevation, partially in section, representing the present improvement. Fig. 2 is a sectional plan view atthe base of the burner through the mixingchamber upon the line 2 2, and Fig. 3 represents the burner and generator without the mantle.

The petroleum or other liquid hydrocarbon is suppliedvfrom any suitable reservoir. I have represented a reservoir A for the liquid With a pipe 3, which is to extend to the bottorn of the reservoir, or nearly so, and is provided with a tightly-closing valve 4, and inasmuch as the burner in this form of lamp is represented as above the reservoir the surplus air-pressure is made use of in elevating the petroleum, and I find it advantageous to make use of an air-valve and tube 5, to which a pump is applied similar to the pump made use of in intiating the tires ofy cycles, so that the necessary air-pressure can be obtained Within the reservoir A for causing the liquid to rise in the pipe 3, and it is also advantageous to make use of a safety-valve at 6 to yprevent too-great air-pressure being employed Within the reservoir. Any desired distance may intervene between the burner and the reservoir. I

I have shown the burner-base at B, which is hollow and advantageously provided with a finely-perforated or gauze upper end '7, through which the air and gas as they are mixed pass and burn in the form of a nonluminous Bunsen flame, and a suitable Inantle is made use of, upon which the non-luminous llame acts to render it incandescent and luminous. A portion of the mantle is shown at C, and itis advantageous to suspend the mantle from a wire D, secured to the removable holder E, which may also be adapted to receive a lamp-chimney surrounding the mantle, if desired. These parts thus far described may be of any desired character and While advantageously employed in lamps of this de scription may be varied according to the character of the lamp and the place where the same is to be used.

The filamentary tubular generatorF is preferably within the Bunsen flame. It is coiled more or less, and it is of a sufficiently small size not to interfere with the burning of the Bunsen flame or to cause any deflection or cooling of the llame or of the mantle adjacent to the generator. I find it advantageous to make this lamentary tubular generator of a IOO v.

small copper or aluminium tube about one sixty-fourth of an inch in diameter, because the same is adapted to act as a generator and for the passage of the gas to the lamp without interfering with the llame, and the ends of this iilamentary tubular generator are advantageously below the flame and enlarged. I have representedV the enlargement 8 at the entrance end of the filamentary generator and connected to the upper end of the supply-pipe 9. The pipes S and 9 are sufficiently large to prevent their becoming clogged or stopped by any deposit from the liquid hydrocarbon, and

they are heated by the conductivity, so that the liquid is vaporized before passing into the fllamentary tubular generator, and it is advantageous to connect the pipes S and 9 at the coupling-block lO,the one slipping tightlyinto the other and being held by a screw, so that the filamentary tubular generator can be removed and another one substituted should the same become obstructed by any carbonaceons deposit or otherwise.

The discharge end of the iilamentary tubular generator F passes into the mixing-chamber G, which is advantageously in the form of a cylindrical segment or tubular ring around the burner-base B, the end of the filamentary tubular generator being sufficiently enlarged to be held by the screw l1 where it passes through the wall of the mixing-chamber, and there is a needle-valve 12 at the discharge end of the filamentary tubular generator, by which the quantity of gas or vapor issuing into the mixing-chamber can be regulated, and there is an opening at 13 at the end of the mixingchatnber G for air to be drawn in by the action of the issuing jet of vapor, and as these travel together around through the segmental mixing-chamber they become very intimately associated and uniformly diffused, so that the air and gas in a mixed condition passing into the burner-base at lat are well adapted to a perfect combustion at the upper end of such burner-base, the flame being substantially non -luminous and adapted to heating the mantle.

I have represented the lamentary tubular generator as bent in the form of a loop and adapted tothe Bunsen llame passing up and all around the tubular generator, so as to highly heat the same, and this filamentary tubular generator is not sufliciently close to the mantle to injure the same by contact or to lessen the heat and luminosity of such mantle, and the vapors become so intensely heated speedily becomes sufficiently hot to act upon the vapor and adapt it to mixintimatelywith the air in supplying the Bunsen burner and that as soon as the flame is extinguished the fllamentary tubular generator cools so rapidly that there is no risk of vapors or gases forming after the supply of liquid has been cut off or the iiame extinguished.

I claim as my inventionl. The combination with the hollow burnerbase for a Bunsen flame and an incandescing mantle and a mixing-chamber, of a filamentary tubular generator passing up to the flame and descending to the mixing-chamber and having the end tubular portionsof larger exterior diameter, and a clamp for removably securing one end to the supply-pipe for the liquid hydrocarbon and means for securing the other end at an opening into the mixingchamber, and a valve passing through the mixing-chamber and acting at the jet-opening in the end of such ilamentary generator, substantially as set forth.

2. In a lamp having an incandescing mantle and a hollow burner-base below the mantle, of a mixing-chamber passing around the burner-base, a supply-pipe for liquid hydro- IOO carbon and a iilamentary tubular generator extending from the supply-pipe up into the flame and descending to the end of the mixing-chamber, a valve for regulating the discharge of the vapors from the lamentary generator into the mixing chamber, there being an opening for the admission of atmosphere at the end of the mixing-chamber adjacent to the end of the tubular generator and an opening from the inner end of the mixing-chamber into the hollow burner-base, substantially as set forth.

3. The combination in a lamp for petro leum or similar hydrocarbon, of a hollow burner-base and an incandescing mantle, a pipe for supplying liquid hydrocarbon and a mixing-chamber passing around the ibase of the burner and to which the end of the supply-pipe is connected, a ilalnentary generator passing up into the flame and descending, an enlarged valve-shaped connection at one end and means for clamping the same at the end of the supply-pipe, the other end of the iilamentary generator being of larger external diameter and passinglinto the mixing` chamber, a valve acting at such end, there being an adjacent opening into the mixingchamber for the supply of air and an opening from the mixing-chamber into the burnerbase, substantially as set forth.
