SPECIFICATION forming part of Letters Patent No. 596,765, dated January 4, 1898.

Application filed May 1, 1896. eriallio. 589,897. (No model.)

To all whom, it may concern.-

Be it known that I, ANDREW E. VEON, a citizen oi the United States, residing at Brainerd, in the county of Crow Wing and State of Minnesota, have invented certain new and useful Improvements in Vapor-Lamps, of which the following is a specification.

My invention relates to lamps, and more particularly to lamps for heating purposes and in which a light hydrocarbon is used and vaporized by the heat of the lamp, and has for one of its objects to provide a lamp which will produce an intense heat and at the same time will be entirely free from any liability to explode.

Another object oi my invention is to provide a lamp that may be readily and safely carried in a trunk or traveling bag or outfit without being broken and without spilling or wasting the hydrocarbon with which it may be filled.

Another object of my invention is to provide a lamp which. will not consume thewick or wicks used therein and which will require no further attention than keeping it supplied with the material burned therein and lighting and extinguishing it.

Still another object of my invention is to provide a lamp which will concentrate or focus the flames and heat produced thereby and maintain the same at substantially an unvarying height.

These objects I accomplish in the manner and by the means hereinafter more fully described in detail, reference being made to the accompanying drawings, in which similar letters of reference indicate corresponding parts in all the figures of the drawings, in which Figure l is a side elevation of my improved lamp. Fig. 2 is a vertical sectional View of same on the line a; w of Fig. l, with the cap I removed. Fig. 3 is a top plan view on an enlarged scale. Fig. 4 is acen'tral sectional view of tube In carrying out my invention I provide a reservoir A, preferably of cylindrical form and made of brass or any suitable material and having fixed in its upper end by means of screw-threads a cap B. Centrally fixed in the cap 13 by any suitable means is a tube 0, connecting with the interior of the reservoir A and rising vertically from the cap therein. The tube 0 is of the same diameter throughout its length and is open at each of its ends. The top of the tube is provided with a number of inwardly-projecting points D, formed on the upper end of the tube G by recessing the end of the tube at regular intervals and to the same depth and bending the projecting points or ends-produced thereby in the direction of the center of the tube 0. Concentrically mounted in tube 0 is a second tube E, supported therein by the projecting points D. This tube E is entirely open at its lower end, but has its upper end formed with a cap like the end of a closed thimble and is provided with a small orifice F in the center of the cap. This central tube E is of the same diameter from its lower end to where its sides begin to contract to form the closed or thimbio-capped end thereof. Tube 0 has fitted to its inner circumference a wick G, which extends down in the reservoir. The tube E- is also provided with a wick H, extending into the reservoir. After the wick is inserted in the tube 0 the second tube E is pushed through the tube 0 until it projects a slight distance beyond the upper end thereof, it being held securely therein by the contact of the wick in tube 0 against its outercircumference and the inwardly-projecting points D, formed in the end of the tube 0. The wick G in the outer tube 0 is not carried to the extreme top thereof, but rests at a point where the flame of the burning fluid does not reach it nor char it. The wick in the inner tube E is not burned, and neither of the wicks G and H will need renewing if they are properly adjusted in their respective tubes. W'hen the reservoir A is supplied with a suitable hydrocarbon and the wicks and tubes properly adjusted therein, the application of a light to the end of the tube 0 will produce a flame which in turn vaporizes the fluid within the upper end of the tube E and forces a jet of vapor through the orifice F in the end of the tube and which is in turn ignited. The heat surrounding the tube E, produced by the flame at the top of the outer tube 0, will cause the flame of the vapor issuing from the orifice in the tube E to be projected vertically to a distance of several inches. The height of the flame proof the hydrocarbon-flame and of the vapor- This construction not only utilizes duced at the end of tube E depends upon the distance that this tube projects abovetubc 0. Increasing the height of tubeE increases the length of the flame arising therefrom. This jet of burning vapor formsthe central part of the flame produced by the lamp and lifts the flame arising from the outer tube i T reservoir, but it is obvious that the shape and dimensions of the rerservoir may vary with-' and carries it upward, the result being acsteadier and more intense flame than is possible with asingle-wick tube.

The hydrocarbon which I prefer to use in my improved lamp is alcohol; but it makes no material difference whether the alcohol used is made from wood or grain so far as being, however, moreeconomicalto use woodalcohol.

A cap I is provided for covering the ends of both of the tubesto prevent the escapeof the fluid therefrom.

I am aware that it is not new to construct a vapor generator and burner havinga central tube mounted in a wick-tube for generating the vapor, the central tube having a hollow cylinder mounted on its top and projecting around its sides to a distance therefrom, the cylinder having apertures in its circumference from which the vapor is projected horizontally, and-I am also aware that itis not new to surround a central tube thus constructed with a series of tubes the flames from which are directed against the lower end of the cylinder. Such constructions instead of concentrating all of the flames and the heat produced by the lamp at a point above the end. of the central tube and rendering it possible to utilize both the heat and flame thereof, as is the result in my construction, radiates both heat and flame from a common center and renders such a lamp-useless for the purposes of my invention.

The essential feature of my invention consists in using the flamefrom a Wick-tube surrounding a tube provided with a Wick rising near its upper end, said end being closed with a cap having a vent or orifice therein to. permit the escape of a jet of vapor, saidvapor-tube adj ustably supported within the wick-tube-with its top a distance above the wick-tube whereby the flame and heat of the vapor and the flame and heat from the wicktube are united and concentrated and the united flames supported at a uniform height, the height depending on the height the vaportube rises above the outer tube. This fea:

ture utilizes in a concentrated form the heat flame.

driven away from the center the vapor-flame to draw the hydrocarbonflame to itself, but also draws or sucks the oxygen of the-air intothe flame, whereas in the usual construction the air is forced or from which the flames are radiated.

I have shown and described a cylindrical out departing from the principles of my invention. The direction in which the tubes project'from the reservoir may also vary, and

curved tubes may be used instead of straight j Ones;

concerns the quantity of heat produced, it

I claim as new, and desire to secure by Letters Having thus described my invention, what Patent, is

1. A vapor and hydrocarbon burner consisting of a wick-tube, open at its upper end, carrying a wick and connected with a hydrocarbon-reservoir, a capped tube adjustably supported in said wick-tube, and a vent in themiddle of said cap, substantially as shown and described.

'2. In a vapor and hydrocarbon burner for uniting and concentrating theheat and flame of a hydrocarbon with the heat and flame of a jet of vapor produced thereby, the combination with a wick-tube open at its upperend and'connected at its lower end with a hydrocarbon-reservoir, of a tube having its upper end closed with a cap, and having a vaporvent in the center of the top of said cap said tube being adjustably supported within said wick-tubewith its capped end rising above said wick-tube whereby the flame of the hydrocarbon and the flame of the jet of vapor produced thereby are united and the hydrocarbon-flame supported by the vapor-flame substantially as shown and described.

3. A lamp consisting of a reservoir A, a cap aB secured to said: reservoir, a tube G secured 'insaid cap and carrying a wick G, said tube 'provided with inwardly-turned projections -D, at its upper end, a second tube E, capped at its upper end and provided with an orifice F in the topof said cap, said tube carry- I ing a wick H1, and concentrically supported within the first tube between the projecting points therein, substantially as shown and described.

Intestimony whereof I hereto affix my signature in the presence of'two witnesses.

ANDREW E. vEoN'.
