VAPOR-BU RN ER FOR STOV ES SPECIFICATION forming part a Letters Patent No. 613,347, dated November i, 1898.

Application filed March 26, 1898. Serial No. 6'75 ;252. (No model.)

To ctZZ whom it may concern.-

Be it known that we, FERNANDO 0. WIN- GETT and ANDREW J. BLAOKWOOD, residing at Sterling, in the county of Rice and State of Kansas, have invented certain new and useful Improvements in Vapor-Burners for Stoves, &c., of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to burners for vaporburning stoves.

The objects of the invention are to produce a burner in which vapor shall be developed rapidly and in which the air to support combustion shall serve as a covering to the liquid-vapor supply until near the time for developing into vapor, thus preventing overheating; also, to improve the construction of such burners.

Figure 1 is a broken vertical section of a heating-stove with burner applied. Fig. 2 is a perspective of the flame-shield and supports. Fig. 3 is a broken perspective of lower part of reservoir and connections. Fig. 4 is a broken perspective of dish, plate, and air-pipe passing through the same.

The stove-body A and legs or supports B may be of usual construction, although we have devised a stove with internal pipes to which this burner is particularly adapted. It is preferable that the stove-body be at its lower end generally circular and tapering upward; but this is not imperative. The parts of the stove are generally of thin metal.

The burner can be used in any heater or cook-stove and changed in form to suit the va. rious stoves.

The stove-bottom or drip-piece C has a central air-tube D firmly connected thereto. At the upper end this tube has side perforations D, and the tube D supports and is closed by the bottom plate E of the double convex gasreservoir. The top plate E of this reservoir is connected to the bottom plate by a gastight joint, and in some cases the reservoir may be cast integral and may be made in oblong form for cooking-stoves or furnaces.

The supply-pipe F, which conveys the supply of hydrocarbon liquid or gas to the reservoir, passes centrally through the pipe D and extends into the reservoir E. Inside the reservoir the pipe F is preferably closed at the top and has a number of side openings F, which tend to distribute the entering liquid or vapor in the reservoir. Thus openings from pipe D convey air outwardly under the bottom of the reservoir, while the openings from pipe F convey liquid or vapor into the reservolr.

The pipe F is supplied with liquid hydrocarbon in usual manner and has a shut-off valve, as usual. Whether this material onters the reservoir in form of a liquid or vapor it is soon formed into avapor when the burner is in use.

From near the top and inside of the reservoir E two or more pipes H extend downwardly through the bottom plate and then curveinwardly. These pipes may terminate in burners H, as shown in Fig. 3, or the pipes may be connected to an annular tube I, having a series of holes pointing inwardly, as in Fig. 1. In either case the pipes H will take in vapor from near the top of the reservoir and will convey it to a burner which directs the vapor generally toward the central airtube D. This has the effect to heat the air in tube D and cause it to rise rapidly in such tube and pass out against the lower plate of the reservoir, where it mingles with the flame from the burners and passes outwardly and up around the edge of the reservoir.

A reversed hollow frustum or shield K is suspended from the reservoir E by bars L, and the lower edge of this shield is preferably a little below the burner. This shield prevents air-currents close to the burner and induces a steady, even, and quiet combustion, while permitting the air to reach the flame from below and permitting the flame to pass out around the reservoir, the suspensory devices L ofiering little resistance.

The vapor-supply is first developed by the application of temporary heat in usual manner. As soon as Vapor has developed in reservoir E, under the influence of heat, this va por will be driven out the pipes H to the burners H or I, where it is ignited. The burners facing inwardly toward the pipe D cause the air therein to become heated and flow out the apertures D. At the same time the action of the heat on the lower part of the reservoir E rapidly develops vapor in such reservoir. The supply of hydrocarbon through pipe F regulates the combustion. The form of the reservoir E gives it special value in deflecting the flame outwardly and in developing the vapor internally, and the vapor-supply being taken from near the top of the reservoir insures that the purest and rarest vapor in the reservoir shall be conveyed to the burners.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. A burner for hydrocarbon vapors and gases, consisting essentially of a double convex reservoir having a central liquid-supply pipe with side openings inside the reservoir,

exit-pipes extending downward from the upper part of the interior of the reservoir to burners directed toward the supply-pipe below the reservoir, and an air-pipe surrounding the liquid-supply pipe, open at the bottom and terminating below the reservoir, said air-pipe having air-openings immediately below the reservoir, substantially as described.

2. The burner described having its inner liquid-pipe leading to the reservoir, the outer air-pipe surrounding the liquid-pipe and hav-' ing its inlet-opening below the burner, and air escape openings below the reservoir, burner-pipes leading down from the reservoir and having burners directed toward the central air-pipe, and a shield surrounding the burners, all combined substantially as described.

3. In ahydrocarbon-burner, the convex reservoir, liquid-pipe entering the same centrally and air-pipe surrounding the liquidpipe with inlet below the burner and outlet below the reservoir, burners connected to the reservoir and directed toward the air-pipe,- and the frusto-conical shield supported from the reservoir, all substantially as described.

In testimony whereof we affix our signa-' tures in presence of two witnesses.
