HYDROCARBON-VAPOR GENERATOR."
. SPECIFICATION forming part of Letters Patent No. 735,831, dated August 1 1, 1903., Application fil d August 28, 1901- Serial No. 78,568. (No model.)
To all whom, it may concern:
Be it known that I, JOHN FRANKLIN SHELF TON, a citizen of the United States, and a resi-' dent of Fort Worth, in the county of Tarrant and State of Texas, have invented new and useful Improvements in Hydrocarbon-Vapor Generators, of which the following is a full, clear, and exact description. 7
My invention relates to. hydrocarbon-gen erators, and more particularlyto means for. causing the hydrocarbon fluid. to vaporize readily.
Reference is to be had to the accompanying drawings, forminga part of this specification,- in which similar characters of reference indicate corresponding parts in all the figures.
Figure 1 is a perspective view of my device. Fig. 2 is a vertical section on the line a; a; of Fig. 1 looking in the direction of the arrows. Fig. 3 is a vertical section on the line y y of Fig. 2 looking in the-direction of the arrows. Fig. 4. is a horizontal section on the line .2 z of Fig. 3.
The main burner is screw-threaded and is mounted upon a funnel-shaped end 1 of the tube 2, which is provided with a T 3, into which are inserted the large air- tubes 4 and 5 for the purpose of supplying the burner with air, this arrangement'constituting a form of the Bunsen burner.
Secured to the T 3 is a head 27, provided with depending tubular pockets 11, 13, and 15 and connected with the hydrocarbon-supply pipe 18. The hydrocarbon liquid enters through the pipe 18 and fills the internalcavi-- ties 12, 14, and 16 of these pockets, first fill-' ing the cavity 12 of the pocket 11, thence flowing obliquely to the right fills the cavity 14 of the pocket 13, thence proceeds across through the passage 17 to the cavity 16 of the pocket 15, after filling which it proceeds through the passages 21, 22, and 23, whence it divides, a part going down into a tube 28 and a part going into the conical passage 9 and thence to the jet .10 in the nipple 11. This jet 10 is controlled by the needle-valve 8, which is mounted upon the stem 6 and terminates in the hand-wheel 7,and by turning this hand-wheel to the right or left the escape of the liquid through the jet 10 is governed. The part of theliquid which descends ture of the surrounding parts.
through the tube 28 enters a narrow passage mission of the hydrocarbon liquid through the conical passage 41 to the open space 42' in the crooked air-tube 29.
Surrounding the tube 28 is a jacket 32,
mounted upon the tubular frame 31 and supporting the wire-gauze 33. The end 42 of the air-tube 29 is open. At 30 are holes in the air-tube, these holes being distributed upon each side of the ridge 39, containing the passage in which the needle-valve 40 works. An iron hood 31 loosely surrounds these holes, as shown more particularly in Figs. 1 and 2. 19 is a stopper, made, preferably, of asbestos wrapped with gauze. Its object is to curtail the flow of hydrocarbon liquid through the tube 18.
The operation of my device is as follows: A volatile hydrocarbon being admitted to the apparatus by means of the pipe 18. fills the depending pockets and adjacent tubes, as above described. By turning the hand-Wheel 37 a little of the liquid is injected into the large crooked tube 29 and immediately vaporizes at a rate depending upon the tempera- The free air enters through the opening 42 and mingles with the vapor, thus forming an aerated vapor capable of combustion. A match now being applied to the gauze 33 and also to the ends of the iron hood34 ignites the vapor in two places. If desired, the formation of vapor in the crooked air-tube 29 can be facilitated by heating said air-tube slightly by the external application of a match or torch before igniting the vapor. The vapor passes through the gauze 33 and readily burns above the same. It also passes downward through the holes 30 and burns around the lower part of the frame, more particularly at the ends of the iron hood 34. It will thus be seen above the gauze 33 there will beablaze, which I term a subfiame, and that at the extreme lower part of the apparatus, particularly at the ends of the iron hood 34, there is another small flame, the two flames being supplied by two branching portions of the flowing vapor. The flame at the ends of the hood 34 heats all of the parts immediately adjacent and serves to vaporize the little portion of hydrocarbon fluid which enters the tube 29 through the jet 41. This vapor passes upward out through the gauze 33 and also downward through the holes 30, thus making two distinct flames, as above described. The flame emanating from the gauze 33' serves to heat the depending pockets ll, 13, and 15, the tube 28, the head 27, the T 3, and the air- pipes 4 and 5 and at the same time to vaporize such of the hydrocarbon liquid as passes through the'jet 10. Itis at this point that the vapor is formed in large quantities to feed the burner proper, this vapor being immediately admixed with more or less air entering through the passages 43 and 44 of the air- pipes 4 and 5, this action being the same as in the well-known Bunsen burner. The vapor thus aerated passes downward through the tube 2 to the main burner.
It will be noticed that the main volatilizing device is equipped with a series of pockets forming aseries ofdistinct volatilizing-chambers adapted to be charged successively with hydrocarbon and that it has a branched or divided fuel supply, one of said branches leading to the pipe having the Bunsen airfeed, while the other branch of said divided passage communicates with the downwardlyextending tube 28 and is adapted to supply the overflow and non-volatilized hydrocarbon to the crooked air-tube 29, thus causing the overflow liquid to be vaporized in the tube 28, and the resulting vapor is commingled with air before the combustible mixture is admitted to the subflame-burner.
The tubes 4, 5, and 2, connected with the head 27, constitute a Bunsen air-feed for the main pipe adapted to supply a series of burners, and this air-feed device receives the fuel from the vapor-passage in the head 27, so that the fuel and the air will be commingled previous to supplying the combustible mixture to the main pipe.
Thejacket 32 and the gauze 33 constitute the subflame-burner, which is situated immediately below the depending pockets forming the main volatilizing device. This subflame-burner is supplied with vapor mixed with air from a local or secondary volatilizing device. This secondary volatilizing device is formed by a ridge 39, containing the jet 41 and the regulating-valve, and said jet discharges the vapor directly into the crooked air-tube. The secondary volatilizing device receives the fuel through the tube 28, which is carried from the head 27 directly through the subflame-burner, and the vapor supplied by the jet 41 and the crooked tube 29 is mixed with air, which is admitted freely to the crooked tube 29 through the mouth 42. This crooked tube, having the free-air inlet communicating with the jet 41 and with the subflame-bnrner,produces or constitutes a second Bunsen air-feed for the subflame-burner. A secondary burner is employed in operative connection with the secondary volatilizing device to heat the latter, this secondary burner being formed by the ports 30 and the surrounding hood 34. The ports 30 are supplied with vaporized fuel, which is conveyed thereto through the secondary volatilizing device and its jet 41 and the crooked air-tube 29.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1.
