VAPOR-BURN ER STOVE.

SPECIFICATION forming part of Letters Patent No. 416,040, dated November 26, 1889.

Application filed June 2l. 1889. Serial No. 315,112. (No model.) v l To all whom it may concern:

Be it knpwn that I, HENRY RUPPEL, of Cleveland, .in the county of Cuyahoga and State of Ohio; l1ave invented certain new and useful Improvements in Vaponurner Stoves; 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 pertains to make and use it, reference being had to the accompanying drawings, whichform part of this specification.

, My invention relates to an improvement in vapor-burner stoves; and the object-s of myv invention are to dispense with the usual lighting-cup and' substitute therefor a reservoir which is lled with packing, and through which air and gasoline are forced for the purpose of producing vapor, by means of which the central burner can beinstantlylighted; to place upon the stand-pipe a gen erating-chainber which is divided by a partition into two separate and distinct chambers, and which hasa perforated top, the inner chamber being fed with vapor by the central generatingburner and the outer one by the two end burners, the Haine from the generating-chainbers being used both to generate vapor for the central burner and to relight the end burners should they become accidentally extinguished at any time, and to do away with the ordinary needle-valves, which are oper-y ated by hand wheels or levers, and to substitute therefor endwise-moving grooved needle-valves, which are operated by pinions, and which can be changed when they become worn at any one point.

Figure l is a front elevation of a vaporburner stove embodying my invention, the name-plate and the levers connected to the operating-stems being removed in order to show the parts more clearly. Fig. 2 is a side elevation of the same, the end burner being removed. Fig. 3 is a plan view, 4a portion of the central burner being removed. Figs. Il

and 5 are detail views of the slotted nameplate and the levers for operating the valves which control the flow of vapor to'the end burners. ator.

A represents the pipe which conducts gasoline from the tank to the central burner, and

Fig. 6 is a plan view of the gener- B the stand-pipe, upon which the central j generating-burner C is placed. This vstandpipe is connected to a T-shaped pipe or casting D, which is connected to the pipe A at opposite ends or sides, has two connections extending at right angles thereto for the reception of the hollow valve-stem and the reservoir, and another connection d, which eX- tends vertically, and to which the stand-pipe Bis screwed. Leading from the top of the stand-pipe is the vapor-pipe E, which is provided with a controlling-valve E for regulating the iiow of vapor to the central burner C, and from which pipe extends at an angle the pipe G, which has its outer end c turned at an angle so as to be in line with the pipe H, which extends from the central burner C, and which end e contains the needle-valve, which controls the flow of vapor into the pipe II. This needleaf'alve is regulated in the rst instance by means of a screw-plug I, and which is not .afterward changed except when it is desired to clean the needle or the pipe, or under similar circumstances. This needle is thus locked up out of the way, so as not to be injured by persons operating it unnecessarily. The plug-valve E is intended to control the flow of vapor directly from the stand-pipe, and the needle-valve is not to be operated after it is once adjusted.

lleretofore lightingcups have generally been employed for starting `the stove in operation; but these are objectionable on account of the smoke and re and the blackening of the stove wherever the flame touches. In

the reservoir J is used, which is screwed Yupon the arm K, which extends from the coupling D. This reservoir is filled with a packing of any suitable porous material, and extending from the top of the reservoir is the pipe L, which is provided with a stopcock to control the flow of vapor or gasoline through it, and which pipe has its outer end 4reduced somewhat and bent at such an angle as to discharge directly into the pipe H of the central burner C. Extending from the coupling D, in a direct'line with the pipe K, is a second internal screw-threaded pipe M, through which the hollow valve-stem passes. To the outer end of this valve-stem Ico N is secured a bulb or other air-forcing mechanism Q, and connected to the stem is the operating-lever O, by means of which the stem can be revolved. The inner end of this stem N forms a valve and lits into a seat made in the inner end of the pipe K for the purpose of regulating` the .iiow ot' air and gasoline into the reservoir J. When the stem N is given a quarter-turn, so as to move its inner end from off its seat in the end of the pipe K, and the bulb Q or other forcing mechanism is operated, air and vapor are forced into the reservoir J, and from this reservoir, when the stopcock in the pipe L is opened, the vapor passes into the central generator, and from which burner the vapor is lighted. .Afew operations of the bulb oi other ainforcing mechanism will force a sufficient supply of air into the reservoir to supply vapor enough to start the central generator, and then the stem N should be given a quarter-turn by means of the lever O, so as to close the supply of gasoline to the reservoir J. The stop-cock is placed in the pipe L, so that the flow of vapor from the reservoir can be shut off whenever so desired.

By means of the construction above described vapor is always held under pressure in' the reservoir, or can be instantly generated, so that the central burner can be lighted like gas,l thus enabling the ordinary light-ingcupl toy be entirely dispensed with.

Extending downward from the central burner C is a pipe R, which conducts a portion of the vapor from the mingling-chamber into the inner chamber S of the generatingchamber. This generating-chamber T is di-l vided by a vertical partition U into the outer chamber V and the inner chamber S, and the two cham bers are provided with a perforated cover a, through which the vapor escaping from one or both of the chambers burns. inner-chamber S is in contact with the upper end of the stand-pipe; but the heat from this chamber is intended to vaporize the fuel in thestand-pipe B and to heat the two supplypipes W, through which vapor passes to the end burners X. The'two chambers S V have no 'communication with each other, and while the chamber S is in use all the time that the centralburner is being used the outer chamber V is only brought into use when one or both of the end burners X are being used.

The flow of the vapor from each of t-he pipes W is controlled by an endwise-moving needle-valve Y, which has a series of vertical groovesmade in its stem,an d which valve is operated by the pinion Z,the teeth of which catch inthe grooves and move the needle back and forth as the pinion is caused to partially revolve bythe stem A'. Each of the valves Y isl grooved circumferentially in its stem, so that when any one part becomes worn by the operation of the pinion Z the valve can -be turned partially around, and thus bringa new' surface into play. This construction also enables the valve to be removed and replaced,

The.

so as to present a new surface-at the pointin case the valve should not tit perfectly to its seat.

If the grooves or teeth upon the valve-stem were made upon one side only, the valve would always have to be used in just one position, because thepinion cannot operate it at any other point. The vaporescapes from the end of the pipe W into the conducting-pipes B' of the end burners X. Extending parallel with the conducting-pipes B' and connecting with the outer chamber V of the generator T, at one end and the bottom of the outer burners X, are the pipes C', through which a portion of the vapor from each end burner X passes backward to the generator, and, escaping from the top of the chamber V, is burned at that point. Extending from, each' end burner X, "and having its inner open Aend placed just above the top of the chamber V, is a conducting-pipe D', through which a-portion of the vapor escaping from the end burner or a portion of the vapor escaping from the chamber V passes. Should the end burner become accidentally extinguished, a port-ion of the escaping vapor will-be caught in the end of the pipe D and pass backward toward the generator at the same time thata portion of the lighted vapor from the chamber V will enter its inner end. The consequence is that flame will follow the gas through th'epipe D and light the extinguished burner; or should the flame arising from both chambers of the generator become extinguished av portion of the escaping vapor will be caught by theinner end of the pipe D' and beV carried out toward the end burner, at which -point'it will be ignited, and then the flame will be passed backward through the pipe D' for the purpose of relghting the generator. InI this manner, should any one or two of the burners become extinguished they will be' automatically relighted by having the amepass through the pipes D', as above described. Should the central burner become extinguished at any time and the generator remain lighted, the flame will pass up around the sides of the burner C and relight.

By the constructionl above describedI lrave, by dividing the chamber T into two annular chambers, combined the ordinary iiame of the inner chamber S with the hotter iiame of the mingled vapor and air from the outer chamber. Incase the central burner alone is used the ordinary iiame from the chamber S is sufficient-to generate the vapor andthe IOO IIO

formed in the name-plate. These slots are preferably made curved, and at one end of each slot there is made a notch or shoulder L' behind which each handle or lever I' drops for the purpose of locking the valve Y in position when closed. These notches or shoulders are formed so that the handle or lever cannot be accidentally moved in such a manner as to open the valves Y and permit an escape of vapor by having the dress or some object strike against them. The other end L" of each of the slots from the shoulders or recesses L' are suitably enlarged, so as to allow the levers or handles to drop down therein, and thus hold the valves open al'ter the burners have been lighted.

Having thus described my invention, I claim- Y 1. The combination, with a vapor-burner, of an air-forcing device connected to the suppl y-pipe which extends from the tank, a reservoir also connected to the supply-pipe and into which air and gasoline are forced, and a pipe which extends from the top of the reservoir and conducts the vapor to the burner, substantially as shown.
