HYDRoCARBoN-VAPORBURNER.

SPECIFICATION forming part cf Letters Patent No. 769,981, dated September 13, 1904.

Application iiled December l, 1899. Serial No. 738,914. (No model.)

To @ZZ whom. it may cancer-n:

Be it known that I, HENRY BoUNDs CARY, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Improvement in Hydrocarbon-Vapor Burners, of which the following is a specification.

This invention relates to improvements upon the form of burner known as the Hoskins hydrocarbon -gas burner for blast-furnaces and other purposes shown in Letters Patent of the United States issued to John Hoskins November 14, 1882, No. 267,431.

An object of this invention is to produce a burner which will burn more noiselessly and more regularly and will not be so liable as burners of this character heretofore made to cool down, and thus allow the raw gasolene.

to be injected into the furnace.

The accompanying drawings illustrate my invention.

Figure l is a perspective view of my newlyinvented gasolene-vapor generator and injector for assayers furnaces. Fig. 2 is a section of the same cutting across the intraining-tube and along the retort-passage. Fig. 3 is a longitudinal section on line 3 3, Fig. 2, extending along the mid-lines of the gasolene-intake passage and the vapor-passage.

My invention comprises a gasolene-vapor generator and injector for assayers furnaces formed in an integral casting having a head or retort portion, preferably Iiat, and an elongated duct portion projecting from one side thereof, preferably at right angles. The head is enlarged sufficiently to expose a large area to the heat of the furnace and is of such thickness as to retain the heat after it has been absorbed and cause vaporization to continue from that source alone. The head preferably consists of two portions, the front or face 4 of which is of a greater area than the rear or shouldered portion 4 and in the present instance is circular, while the rear portion is rectangular. This construction gives the greatest possible surface within a given boundary for the face and permits of the rear portion and its attachments lying wholly within said boundary, whereby they are protected and the head may be inserted into or through an opening in the furnace-wall if necessary.

The intraining-tube I is preferably cylindrical and arranged axially relatively to the center of the head, and the gasolene-intake passage 2 and vapor-passage 3 are arranged side by side along the tube and communicate, respectively, with the' ends of the retort-passage 5 in the head adjacent to each other and near one corner or shoulder of the rear portion 4.

As shown in Fig. 2, theretort-passage 5 is arranged lying in the four sides of a rectangular quadrangle, the ends of said passage being at one corner of said quadrangle at the 7 same side of the intraining-tube with the gasolene and vapor passages.

6 indicates the jet-piece connected with the discharge end of the vapor-passage, said jetpiece being fastened onto a projecting nipple or tube 7 at the termination of the vapor-passage 3. The jet-piece is arranged axially of the intraining-tube to direct the jet of vapor centrally into the intraining-tube and is at a proper distance from the intake end of the intraining-tube to allow suficient air to be carried into the intraining-tube by the force of the vapor jet. I

In practical construction the four limbs a, b, c, and cl of the retort-passage will be produced by boring, the'iirst limb L being bored from one corner of the retort-piece in to communicate with the gasolene-passage 2, the limb o being bored from the neXt corner of the retort-piece into the limb a, the neXt limb c being bored from the neXt corner of the retort-piece kyinto the limb b, and the limb Z being bored from the next corner of the retortpiece across the end of the vapor-passage 3 and back into the limb c of the retort-passage. limbs a, b, c, and Z will be closed by screwplugs 8, respectively, screwed into the open ends of the limbs and properly cemented with any suitable cement. (Not shown.) By constructing the burner in this manner it can be Then the open ends of the several cast as asolid piece, the tube being cored out What I claim, and desire to secure by Letand the other ducts and passages formed by boring. Open joints from warping or breaking of smaller pieces of metal from the intense heat are thereby avoided, and after the oil or vapor enters the vaporizing passage or chamber it is compelled to pass substantially around the head before it can escape, thereby being vaporized to the greatest possible extent and causing the most complete combustion when it escapes into the furnace.

In practical use the injector is preferably mounted with the gasolene and vapor passages underneath the intraining tube, as shown in Figs. l and 2. The gasolene being admitted through the gasolene-passage 2 must flow up over and around the intraining-tube and over to the other side and will practically fill the passages a b and will flow along the under walls of the passages @and el, thence through the passage 3 and through the jetpiece 6, where it will be ignited.

In practice in starting generators of this character into operation the gasolene is turned on and a portion is caught in a receptacle. The jet-piece is then closed and the gasolene in the receptacle is then ignited and the flame allowed to burn up around the generator until the generator is heated sufficiently to vaporiZe the gasolene. rlhe jet-piece is then opened to allow the jet of vapor to issue and the vapor jet is ignited and blown through the tube in a flame. The emitting end of the tube is then brought to an opening in the wall of the furnace and allowed to blow into the furnace to heat the saine. The reflected heat from within the furnace continues to heat the generator and increase the tension of the issuing vapor until the generator is sufliciently heated to generate a vapor of the required tension.

-ters Patent of the United States, is

A gasolene-vapor generator and injector consisting of an enlarged flat head and an elongated duct portion extending at right angles from one side thereof, said parts being formed integral and said head comprising' a circular face and a shouldered rear portion, said face forming a shield and the rear portion being provided with a passage formed from limbs, each limb extending respectively from one shoulder to the limb from the adjacent shoulder, except the last one, which terminates at a point adjacent to the first limb, a plug in the outer end of each limb, and a jet-piece, the head of the burner being of such area and thickness as to receive and retain enough heat from the furnace as to produce constant vaporization, and the duct portion being provided with three passages, one of which is larger than the others and extends longitudinally entirely through said portion and transversely through the head substantially at the center thereof, and the other passages extend parallel with the larger passage and terminate at their inner ends, respectively, one with the inner end of the last limb of the passage in the head and the other with the iirst limb near its plug, and the outer end .of one of them communicates with the jet-piece in alinement with the larger tube and the other one is adapted to communicate with an oil-supply.

In testimony whereof I have signed my name to this specification,in the presence of two subscribing witnesses, at Los Angeles, California, this 25th day of November, 1899.

HENRY BOUNDS CARY.
