VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 569,524, dated October 18, 1896,

Application filed January 27, 1896. Serial No. 576,974. (N0 model- To @ZZ whom, t may concern,.-

Be it known that I, LOUIS Srociisrnon, a subject of the Emperor of Germany, and a resident of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Vapor-Burners, of which the following is afull, clear, and exact description, reference being had to the accompanying drawings, forming part of this specifica-tion.

My invention relates to an improved construction of self-generating burners for gasolene-stoves and my invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a side elevation illustrative of my invention. Fig. II is an enlarged detail vertical section taken on line II II, Fig. I, with the drip-cup turned to the position shown in dotted lines, Fig. I, and the drum and mixingtube removed, with the exception of a small part of the drum. Fig. III is a detail vertical section through the drum of the burner and showing part of the vaporizer and needle-valve of the burner. Fig. IV is a top view with the drum and mixing-tube removed. Fig. V is a detail horizontal section taken on line V V,Fig. III, and showing the subsidiary burner. Fig. VI is an enlarged detail seetional View of the drip-cup and its extension, the latter for conducting the oil from the jet to the cup when the needle -valve is first opened.

Referring to the drawings,l .represents part of a supply-pipe through which oil is conducted from a tanl; or reservoir (not shown) to the burner. Mounted on this pipe is a vaporizer 2, consisting of a casting, preferably of brass. This vaporizer is made in A form, on the top of which is a head 3. On one side of the vaporizer is a port or passage-way 4, communicating with the pipe l through an inclined port 5. On the other side of the vaporizer is a port or passage-way G, which oommunicates with the port et at the top of the vaporizer and the lower end of which communicates through a lateral port 7 with the transverse bore S, in which the needle-valve 9 iits and works, the bore 3 being made in the casting that forms the vaporizer. The needle-valve controls the jetcpening 10 of the generator,

Il represents the drum of the burner. This drum has a central cone-shaped tube 12, open both at top and bottom for the passage of air. The top 13 of the drum comprises the burnercap, and it is provided with a number of saw cuts or kerfs, through which the vapor passes. The cap has a central iiange I4, iitting over the upper end of the tube 12, and an outer flange l5, fitting within the body of the drum, as shown in Fig. III. On one side of the tube l2 and located between the vaporizer and the inner end of the mixing-tube is a subsidiary burner 16, formed of a casting fitting in an opening made in the tube and held in place by bolts or rivets 17. (See Figs. III and V.) This burner has a number of slits or kerfs 18, through which the vapor passes and is burned in close proximity to the vaporiZer-casting 2. The casting 2 is provided with a lip 19, iitting beneath the burner 16 and serving to prevent the iiame of the burner from reaching the jet IO.

The drum Il has a bottom 20, in which are made two perforations 2l to receive studs 22, extending upwardly from arms 23, formed upon the casting 2. The drum is simply placed over the vaporizer with the holes 2l registering with the studs 22, and when the studs enter the holes the burner is supported in position for use, the three-pronged head of the vaporizer bearing against the upper end of the tube l2 at three different points, thus steadying the drum, these three bearing-points operating in conjunction with the lip 19, upon which the subsidiary burner bears, the lip 19 being on the quarter of the vaporizer not having an arm of the head 3.

2i represents the U-shaped mixing-tube, the mouth of which is placed opposite and a short distance away from the jet-opening l() and the other end of which communicates with the drum l1 in front of the subsidiary burner, as shown in Fig. III. This mixingtube is made in form or shape as shown in Fig. I, and thereby is produced a mixing tube wh ich projects but a short distance from the drum relatively to the amount of travel that the vapor and air have through the tube, this long travel providing for a thorough mixing of the air and gas. The mixing-tube is bolted or riveted to the bottom of the drum 11, as shown at 25. By removably or de- IOC) tachably supporting the drum on the vaporizer it can be simply lifted olf with the mixing-tube and the parts quickly and conveniently cleaned and then replaced.

2G represents the drip-cup. This is made in approximately elliptical or oblong shape, with a handle 27 at one end and a vertical extension 28 at the other end, the inside of the extension being dished out, as shown in Fig. VI. The cup has a central opening to receive the pipe l, which supports it and around which it swivels. The cup is supported -between a lower collar 29 and an upper collar 30 on the pipe l. (See Fig. II.) In starting the stove the cup is swung around into the position shown by dotted lines, Figs. I and lV, bringing the extension 2S in front of the jet-opening 10. The needle-valve is now opened, and oil issuing from the jotopening is conducted by the extension 2S to the cup 2G. Then the cup has received a sufficient amount of oil, the needle-valve is closed and the oil in the cup ignited, thus preliminarily heating the vaporizer. Then the oil in the cup is consumed or nearly consumed, the cup is swung around to the position shown in full lines, Figs. I and IV, to carry the extension 28 away from the jetopening. The needle-valve is now opened and gas mixed with air is conducted through the tube 24: to the interior of the drum ll, and a flame will now burn both at the cap 13 and the subsidiary burner 1G, this ignition taking place from the burning oil in the cup, or if the oil in the cup has been fully consumed before the needle-valve is opened the second time it will be necessary to apply a match to the burner-cap, from which the subsidiary burner will be automatically lighted.

Surrounding the lower end of the vaporizer is a wire-gauze approximately elliptical or oblong ring 3l, having an oval upper end, and which directs the flame from the cup 26 upwardly and causes it to surround and envelop the vaporizer. This ring is supported on an approximately elliptical or oblong base 32, supported by the ring or collar 30 by means of arms extending from one to the other, these arms being shown at 32% On one side of the cup 26 is a lug or ear 33, which comes against the base 32 of the ring Sl when the cup is moved to the position shown in full lines, Figs. I and III, and serves to limit the movement of the cup in this direction.

Screwed over the end of the jet lO is a guard 34, that serves to further prevent the gas issuing from the j et-opening bein gignited from the subsidiary burner.

35 represents bolts passing through ears 36 on the cap 13 and through ears 37 on the bottom 2O of the drum and serving to hold the cap in place.

In my improved construction of burner the vaporizer is located centrally within the drum, where the natural tendency is for it to be kept warm, and the subsidiary burner is in' the central tube of the drum and keeps the vaporizer heated to a high temperature.

I claim as my inventionl. A vapor-burner comprising a drum having a central tube, a vaporizer located within the central tube, having a laterally-extending lip and a valve located therebeneath, a mixing-tube extending from the outlet of the valve to the drum and a subsidiary burner located within the drum above the lip between the vaporizer and the outlet of the mixin g-tube; the lip'servin g to pre vent the flame of the subsidiary burner passing downward to the valve; substantially as described.

2. A vapor-burner comprising a drum having a central tube, a subsidiary burner located in one side of said tube, a vaporizer having a lip extending beneath said subsidiary burner and a triangular head adapted to bear against the upper end of said tube, a valve located at the base of said vaporizer and controlling the jet-opening of the valve, and a mixing-tube extending from a point in proximity to said jet-opening to said drum; substantially as set forth.V

3. A vapor-burner comprising a drum having acentral tube, a vaporizer located within the central tube having a valve located therebeneath, a mixing-tube extending from the outlet of the valve to the drum, a subsidiary burner located within the drumvbetween the vaporizer and the outlet of the mixing-tube, and the guard secured over the end of the valve for preventing the gas issuing therefrom passing to the subsidiary burner thereabove; substantially as described.

4. A vapor-burner comprising a vaporizer of A shape having ports extending therethrough and formed with lateral arms having vertical studs, with a three-pronged head, and with a lip, the burner-drum having holes registering with the studs, a central tube provided with a subsidiary burner in the wall thereof, and the mixing-tube, the burnerdrum being supported removably in position for use by the three-pronged head bearing against the upper end of the central tube in conjunction with the lip on which the subsidiary burner bears, substantially as described.

5. A vapor-burner comprising a vaporizer having a transverse valve at the base thereof, a guard mounted on the jet end of the valve, the approximately elliptical or oblong basering at right angles to the valve, the approximately elliptical or oblong wiregage ring seated on the base-ring, the approximately elliptical or oblong initial heating-cup provided with a vertical extension and rotatable beneath the base-ring; substantially as described.
