NICOLAS LO'UKITSCH POUSGHKAREFF, OF MOSOOXV, RUSSIA.

VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 323,594, dated August a, 1885.

Application filed February 18. 1884.

To all whom, it may concern.-

POUSOHKAREFF, a subject of the Czar of Bussia, and a resident of Moscow, Russia, have invented certain Improvements in Vapor- ,urners, of which the following is a specification.

My invention relates to that class of burners employed in vaporizing and burning volatile hydrocarbons for illuminating purposes, the object being to produce a simple and inexpensive burner that will effect a more peri'ect combustion of the carbon than most burners of this character, and at the same time be safe from explosion and elegant in appearance.

The novel features of my invention will be hereinafter set forth, and particularly defined in the claims.

In the drawings,which serve to illustrate my invention, Figure l is a vertical section taken in the plane of the axis of the burner, the view also showing the reservoir in section. This figure shows the reservoir set in the wall and the burner arranged as a wall-bracket. Fig. 2 is an axial section of a modified form of my burner. Fig. 3shows three varieties of perforated burnertipawhich will be hereinafter de scribed. Fig. 4 shows awire I employ for inserting-the wick. Fig. 5 gives two views of the sliding ring, its stem, and its conductingspurs on a larger scale than the same are shown in Fig. 2. The function of this device will be hereinafter explained. Fig. 6 isa view illustrating, on a smaller scale,the arrangement of several of my burners in a cluster, all the burners being supplied from one reservoir.

Referring to Fig. l, A is the reservoir for supplying the burner with the necessary liquid hydrocarbon as benzine, for example. This reservoir is set or embedded either wholly or partially in the wall B, in order to give it a firm support and enable it to sustain the burners, to better protect it against accident from fire or other causes, and to conceal it from sight for obvious esthetic reasons.

0 is the pipe which conveys the liquid from and to the reservoir. For conveniencein shifting the burner from side to side and to and from the wall, I prefer to joint the pipe 0, as at a a, in a manner similar to that in which ,folded at its middle.

(No model.)

gas-brackets are jointed. The pipe 0 connects with the cup-like substantially-imperforatc base D of the burner, which may be of porcelain or other similar material.

Fixed in base D is a metal holder, E, which rises a little above the level of the top of the reservoir A, and which is exteriorly screwthreaded at its top.

F is the wick-tube, which in this case is open at the top and which is provided with an internally screw threaded flange collar, 1). adapted to screw onto the upper end of the holder E when the wicktubeis inserted therein, as shown.

G is the perforated burner-tip, which is in the form of a cap, and is made to fit tightly upon the upper end of the wick-tube. This tip I prefer to make of silver or some other metal possessing great conductivity, and I provide it with one or more projections or spurs, c, also preferably of silver, which are in contact with the flame or under its influence, and conduct heat to the top, for reasons that will be more fully described hereinafter. H is the wick, which may be of any substance usually employed for raising liquids by capillary force. In the present case I have shown the wick This wick I insert by means of a wire, (I, (see Fig. 4,) having abranch bent at right angles at its end, which branch is inserted in the bight of the wick and the whole pushed into the position shown. The wire d is allowed to remain in place in the wicktubc.

I is a tubular exterior envelope, which fits substantially air-tight in a socket in the base D, and rises nearly to the top of the burnertip G, as shown. This envelopeI usually make of opalescent or white glass or porcelain, to imitate a candle; but this is not essential. Its function is to cut off the air from the burner and prevent an upward draft of air around the burner-tip, which draft tends to cool the generatingchamber 0, and make the flame smoky from excess of uncombined carbon particles.

I will now point out the mode of filling and using my burner.

The envelope I and the wick-tube are removed, the latter by unscrewing Z. The reservoir A is filled by pouring the liquid in at the open upper end of holder E until theliquid in same stands at about thelevel of the dotted line :0, which shows that the reservoir is about full. The air escapes from the reservoir at a "ery small aperture, 9, in the top of same, as the liquid flows in. \Vhile the lamp is consuming the hydrocarbon this aperture may be nearly stopped, as only air enough need enter to take the place of the liquid as fast as it is consumed. The reservoir being filled, the Wick-tube is screwed and the outer envelope, I, set in place. The proper burner-tip, G, is now slipped onto the wick-tube and the burner ignited. The hydrocarbon vapor collects in the generating-chamber, and escapes at the perforations in tip G, when it is ignited and burns. The heat of the flame is communicated to the walls of chamber 6, and this heat serves to convert the vapor into a gas which will burn with a clear white flame. The chamber 0 being protected against the colder air, and being made of a metal that may be readily and highly heated, the heating of the vapors may be effected with very little flame, and the combustion will at all times approach very near to perfection.

I usually make the burner-tips removable, as shown, and provide several tips, (see in Fig. 3,) differing from each other only in number of perforations in them. One tip may be substituted for another in a moment, and thus the lamp be adapted to furnish atiny flame, as for a night lamp or flames of various sizes for various purposes. The conductingspurs 0 may be made in various forms. In Fig. 3 I have shown them of wire,with a loop formed at the free end of the wire.

The modification shown inFig. 2 differs in construction from the burner just described in these respects: The base D is inserted directly into an ordinary lamp-reservoir, A, which is portable. The wick-tube F is pushed down through a bore in base D,which it fits snugly. This bore serves in some respects the same purpose as the holder E, the liquid being poured in at it preferably in filling the reservoir. The burner-tip G is in this construction formed in one with the wick-tube, the top of the latter being closed and perforated. The chamber 6 is thus formed in the top of the wick-tube itself. The conducting-spurs c are attached to a band, 0, which closely embraces and slides on the wick-tube. This band I usually make of silver, as well as the spurs, as its function is in part to convey heat to the generating-chamber. In order that the band 0 may be conveniently adjusted up and down, I attach to it a wire-stem, h, which passes out through a hole in the base D, which hole it fits snugly and is provided with abranch bent on it, as shown, so that the stem may be conveniently manipulated. This device,which is shown on a larger scale in Fig. 5, is designed to regulate the size of the flame.

The conducting spur or spurs may be attached directly to the top of the wick-tube, where no cap Gris employed. When such caps are used, the size of the flame may be readily varied from that of a night light to one equal to fifteen stearine candles, and by varying the position of the perforations, the form of the flame may be varied, producing flames of a round shape, fan shape, sheaf shape, 850. The perforations in the burner-tip may also take the form of a slit.

I make no claim herein to the reservoir, nor the removable burner-tips, nor the wire for inserting the wicks, nor to the vaporizingchamber on the wick-tube, nor to the conductors 0, nor, broadly, to a close exterior envelope. Some of these features are not new with me, and some form no part of my present application; but

What I do claim is- 1. The combination, in a vapor burner wherein a wick is employed, of the close or imperforate base D, the imperforate and removable cylindrical envelope I, mounted in base D, and the wick-tube F, mounted in said base D inside the envelope I, and provided with a generating-chamber, 6, above the wick, the said envelope 1 extending up nearly to the top of the wick-tube, substantially as and for the purposes set forth. I

2. The combination, in a vaporburner, of the close or imperforate base D, the imperforate outer envelope, I, mounted in said base D, the tubular holder E, fixed in said base D, the wick-tube F, provided with a generatingchamber e, and the screw-threaded flanged collar b, fixed on the wick-tube, constructed to fit over and arranged to screw onto the screwthreaded top of the holder E, substantially as described.

In testimony whereof I have hereunto signed my name in the presence of two subscribing \Vi tn esses:
