VAPOR-LA1VIR To all whom 'it may concern:

Be it known that I, CHARLES HALSTEAD, a citizen of the United States, residing at Brooklyn, in the county of Kings, State of New York, have invented a new and useful Vapor-Lamp, of which the following is a specification.

My invention consists of a vapor lamp adapte'd for us-e with an incandescentmantle to cause a most brilliant light, and for heating purposes.

In order to explain the invention, the accompanying drawing illustrates a satisfactory reduction of the same to practice, but the important instrumentalities thereof may be varied, and so it is to be understood that the invention is not limited to the specific arrangement and organization shown and described.

Figure l represents a vertical section of a vapor lamp embodying my invention. Fig. 2 represents a transverse section of the wick tube. Fig. 3 represents a vertical section of a portion of the same, the shutter of the lamp being in closed position. Fig. et represents a side elevation of one of the caps employed. Fig. 5 represents a vertical section of a portion of the lamp, the shutter being in operative position. Fig. 6 represents a vertical section of a modilication.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings: A. designates the fount of an alcohol or other vapor lamp, and B designates the wick tube thereof, the top C of which is closed and from which rises the vertically arranged rod D, for supporting the mantle E of suitable order.

F designates a cap whose upper end is reduced, forming a neck F which is supported on the Lipper end of the wick tube and depends therefrom. In the side of said cap at or below the neck thereof, are the ports or jet openings G, and in the base of the cap are the ports or air openings H. Rising from said base is the sleeve J, which encircles the lower portion of the cap F and is separated therefrom, forming the passage K.

llithin the cap F is the collar L, which surrounds and closes the upper portion of the wick tube, it being noticed that a passage lWI exists between said collar and cap forming a communication for the ports H and jet openings G, it being noticed that Specification of Letters Patent.

Serial No. 522,959.

the wick tube is vertically corrugated so as to form ducts N on its exterior and chiots P on its interior, the walls of the corrugations having ports Q therein, the latter providing communications for said exterior and interior ducts N, P, as most plainly shown in Fig. 2.

lVithin the upper portion of the wick tube is the finely perforated tube B, which embraces the corresponding portion of the wick B and extends below the base of theports Q, it serving to protect the wick from an excess of heat in what may be termed the burner head, since the wick is removed by said tube R from contact with the inner surface of the wick tube.

S designates the shutter of the lamp, the same encircling the wick tube below the collar M, it being adapted to be raised and lowered, and when in closed position to have its upper end S which is of the form of a gutter to abut against the lower end of said collar, as most plainly shown in Fig. 3, it being noticed that said shutter and the adjacent portion of the wick tube are contained in the cap T, which is adapted to be screwed or otherwise connected with the fount A, said cap having mounted therein the wheel U, which is adapted to engage the rack V on the side of the shutter, whereby the latter may be raised and lowered. In t-he neck or upper portion of said cap T, are ports WV, which as shown in Fig. 1, communicate with the atmosphere and with ports X in the shutter, the latter also having ports Y, which as shown in Fig. 3, are below said ports X, and are adapted when the wick tube is raised to be placed in communication with the ports W, in which case the ports X are closed by the surrounding wall of the neck of the cap, and so cut-olf from the atmosphere. On the top of said neck is the gutter Z, which is adapted to be supplied with alcohol or other inflammable fluid for heating the portions of the lamp above the same for primarily vaporizing the fluid, said portions comprising the burner head of the lamp.

A designates the chimney of the lamp, which is supported by the arms B2, the latter being rested on the fount and engaged by the cap T in any suitable manner.

The operation is as follows-The fount is supplied with alcohol or other suitable fluid and the wick B is accordingly saturated with the saine, the vapor whereof passes through the perforated tube R and ports Q, the shutter S being lowered and the burner head being primarily heated by a small quantity ot' fluid placed in the gutter Z and ignited. The vapor now burns below the bottom of the cap F and the shutter is raised so that its upper end S enters the base of the cap F, so as to close the bottom of the passage M, as shown in Fig. G, when the vapor from within the wick tube is directed through the ports Q into said passages, and from the latter into and through the jet openings G, where it iningles with air admitted to the passage K by the uncovered ports H, the resultant vapoi' then burning in the mantle E. Meanwhile, air iows through the ports lV, in the neck of the cap T, into the ports X of the shutter and through the ducts between the wick tube and the shutter, and mingles with the vapor in the passage M, thus supplying a large volume of air to the vapor for perfect combustion in the mantle and a consequent brilliant light.

Vfhen the light. is to be extinguished, the shutter is raised so as to abut against. the collar L, when the supply ot' vapor from the wick tube ceases, see Fig. 3. As the ports X are closed, and the ports Y are opened, any existing vapor in the wick tube and to 'i of the fount will escape to the atmosphere through said ports Y and the ports lV, thus preventing explosion of the lamp.

Should it be desired to use the lamp for heat instead of light, tl e cap F, the sleeve J, tlie mantle E and mantle support D are removed, when the cup C is placed over the top of the wick tube, when the lamp is inverted and some of the fluid flows through the passages of the wick tube into said cup, when on again turning the lamp to normal condition, the fluid leaves the cup and enters the gutter Z, where as a primer, it may be ignited and so heat the top of the wick tube, to cause effective vaporization of the fluid in the latter, the resultant vapor escaping through the ports Q, where it may be burned.

Having thus described my invention, what I claim as new and desiie to secure b v Letters Patent, is l l.
