(No Model.) R. CONRADER. APPARATUS PoR VAPONIZING AND BURNING HYDROGARBON OILS. PATENT OFFICE. RUDOLPH CONRADER, OF ERIE, PENNSYLVANIA. APPARATUS FOR VAPORlZlNG AND BURNING HYDROCARBON OILS. SPECIFICATION forming part f Letters Patent No. 471,505, dated March. 22, 1892. Application filed October 14, 1890- Serial No. 368,229- (No model.) To all whom it may concern: Be it known that I, RUDOLPH CONRADER, a citizen of the United States, residing atErie, in the county of Erie and State of Pennsylvania, have invented certain new and useful Improvements in Apparatus for Vaporizing and Burning Hydrocarbon Oils; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying draw-` ings, and to the letters of reference marked thereon, forming part of this specification. My invention consists in the improvements in apparatus for vaporizing and burning hydrocarbon oils hereinafter set forth and explained, and illustrated in the accompanying drawings, in which- Figure l is a vertical section of my improved apparatus for vaporizing and burning hydrocarbon oils. Fig. 2 is a side elevation of my improved adjustable air and vapor mixer. Like letters refer to like parts in both figures. In the construction shown of my improved apparatus for vaporizing and burning hydrocarbon oils, A is a supply-pipe for conveying the oil from any convenient storage-receptacle to the vaporizing-chamber B of my apparatus, the pipe A being supplied with a suitable shut-off cock a, the end of the pipe A preferably entering the top of the vaporizingchamber B and having its end capped over and small holes b pierced in the sides thereof, through which the oil passes out into the chamber B. In this chamber B the oil is vaporized, as hereinafter set forth. This vaporizing-chamber B is secured to and a short distance above a burner or fuel chamber C, having small holes c in the upper surface thereof, from which air and vapor or gas intermixed with each other, as hereinafter set forth, issues to supply the fire. From the bottom of the vaporiziug-chamber B a pipe or passage D extends downward through the chamber C to a valve e, preferably secured to the under surface of the chamber C, from which valve e a pipe d extends to an adjustable air and vapor mixer F, connected to the burner or fuel chamber C by means of a larger pipe G, so that as the oil is vaporized in the chamber B by means of the heat produced by l the iiames from the openings c in the burner or fuel chamber C it passes downward through the passage D, the open valve E, and pipe D to the air and vapor mixer F, and thence through the longer pipe G into the burner or fuel chamber small holes c therein to supply the fire. The air or vapor mixer F, I preferably construct of a semi-globular inner shell H, having a central tvapor-jet opening g, through which the gas enters from the supply-pipe d, and in the sides I make a series of larger holes h, through which air is drawn in by the force of the vaporfrom the jet-opening g and carried therewith through the larger pipe G into the burner or fuel chamber O. Around the globular portion of the mixer F, I place Aa loose shell I, provided with holes 11, corresponding in size and number with the holes h in the inner shell H. A set-screw .I is also provided, which passes through a slotted ear jin the outer shell I, by means whereof the outer shell I can be adj usted upon the inner shell H, so as to close the air-openings h more or less, as maybe desired. In this manner I am enabled to supply air and vapor to the fuel or burner chamber C, mixed in such proportions as will insure the most perfect combustion and maximum amount of heat for the amount of oil consumed. To start the apparatus hereinbefore describedin operation, it is necessary when the fire is first lighted to burn a small quantity of the oil itself for the purpose of heating the vaporizing-chamber B to such a point as to vaporize the oil supplied thereto. For this purpose I secure a small cup K between the under side of the vaporizing-chamber B and the top of the fuel or burner chamber C. This cup I preferably supply with small air-pipes lc for conveying air to the central part of the top thereof. I pack this cup K with mineral wool L, suitable to be saturated with oil and operate as a wick. From the bottom of the cup Ka small passage Z extends downward to the chamber N of the three-way valve E. cone m, seats e and e as C, and thence out through the f IOO ' so as to admit a smallsupply of oil. the Wick L to prevent its When starting the burner into operation, the valve is closed upon the seat e, the stopcock d in the supply-pipe A being then opened, It flows into the Vaporizingchamber B and down through the passage D into the chamber'N of the valve E and back upward through the small passage Z, saturating the mineral-wool wick L in the cup K. This wick L can then be lighted, and the flame therefrom, impinging against the under side of the Vaporizingchamber B, speedily heats itsufficiently hot to Vaporize the oil being supplied thereto, when the Valve E is reversed, the cone m, now seated on the seat e', closing the upward passage 'Z and allowing the vapor to pass through the pipe d, the air and vapor mixer v F, and the pipe G into the burner or fuel chamber C and out through the openings c, where it is speedilyignited by the Iiame from the wick L still remaining, which, however, ceases to burn as soon as the oil-supply thereto is consumed. To prevent the oil burning from the wick L from smoking while the vaporizing-chamber B is being heated u p, Isecure a short chimney O, preferably made of metal, upon the top of the chamber C, which chimney surrounds the cup K and thev vaporizing-chamber B, which chamber operating as a deiiector a strong enough draft is thereby produced to produce perfect enough combustion of the flame from smoking while the vaporiZing-chamber Bis being heated up and afterward to concentrate suicient heat around the lchamber B to insure its efficient operation. Itis obvious from the vention` that the vaporizing-chamber B and thel burner or fuel chamber C may be constructed of such shape-either round or ob- 1ong-as may be suited to the stove in which it is to be operated and that one or more of -the air and Vapor mixers or Vaporizing-cham- .for shutting off the iiow description of my inl presence of two witnesses. bers may be used therewith, as may be necessary, according the size or form of the burner or fuel chamber C, without departing from the spirit of my invention. Therefore what I claim as new, and desire to secure by Letters Patent of the United States, is Y l. The combinatiomin an apparatus for vaporizing and burning hydrocarbon oils, of a Vaporizing'chamber or coil and a vapor-fuel burner below said chamber or coil adapted to receive and burn the vapor produced therein, lwithV a supplementary burner and a chimney therefor located under said vaporizing chamber or coil and above the vapor-fuel burner, a pipe extending from said vaporizing chamber or coil to said .supplementary burner for supplying oil thereto, and a valve for cutting vo the supply of oil from the supplementary burner, substantially set forth. l 2. The combination, in an apparatus for vaporizing and burning hydrocarbon oils, of a vaporizing chamber or coil and a Vapor-fuel burner below said chamber orcoil, with a cup-v shaped burner K under said Vaporizing cham-v ber or coil, a chimney 0, surrounding said cup-shaped burner K, vertical air-pipes k, surrounded by a packingof mineral wool L, in said cup-shaped burner, passages D and Z, extendas and for the purpose ing from the vaporizing chamber or coil into, the cup-shaped burner K, and a Valve, as E, of oil to the cupshaped burner K when the vaporizing chamber or coil is sufficiently heated, substantially as and for the purpose set forth. p In testimony whereof I affix my signature iny RUDOLPH CONRADER.
