vAPoRieoRNEav SPEQIFIGATION forming part of Letters Patent No. 506,243, dated OctoberlO, 1893.

Application led June 23, 1898.v

ratecap D, vwhich is* preferably held on vthe 'I adjacent flaring end of the Wick tube, simply Be it known that I, WILLIAMIJ. D. MAST, a citizen of the United States, residing at Buffalo,i11 the county of Erie and-'State of New York, have invented new and useful Improve! ments in Vapor-Burners, of .which the fol1ow' ing is a specification.

Thisinvention relates toa vapor burner for alcohol or similar lamps, and more particu-` larly' to burners of this kind which arepro- `videdgwith an auxiliary wick for starting the vaporization of the alcohol or'- other intlalnmabIeliuid, and a ldevice for extinguishing the Iiameof the auxiliary wick.

The principal object of myinvention is to'A so construct the burnerthat eitherv the flame prove theburner in several details struction.

,I fis a similar view of the burner and the alcohol Y of the auxiliary wick .alone or the flames of'4 'both the main and the auxiliary wick may bel readily extinguished without the use of a separate cap or'sixnilar device.A l ;.My'invention has the further object to iin-` In the. accompanying dralwings'g#-llig'g'ure 1' is a' sectional elevation of an alcohol 'larnp containing my improvements, showing thev extinguisher in its lowered position. Fig-2 pot or receptacle, showing the extinguisher raised to the position inwhich it extingu'ishes. the ame of the auxiliary wick.' Eig. `3 ,is a horizontal section in line. 3--3, Fig. 2. Fig. L

is a vertical section of thupper part of the alcohol pot showing the spring for 'holding the operating shaft of the extinguisher against turning.

C is the main wick tube arranged centrallyin the alcohol pot and extend-ing thronghan opening in the top of the pot, and Cisthe wick arranged in said tube.. This wick tube f is preferably cylindrical'and open at ts'lower end to permit the alcohol to reach the wick,

while its upper end v is closed by 'an imperio- A` by frictional contact, so that it may be easily detached, if desired.

'In using the lamp, the extinguishing tube is lowered by means of its operating shaft to the position shown in' Fig. 1,in which position its upper end is below the upper end of the auxiliary wick. The latter is then lighted, whereby the perforated enlargement vof the main wick tube is heated and the alcohol or other fluid is vapori'zed. The vapor issu'- ing from the perforatiousify the main wick tube is next ignited, after which theiiame of the auxiliary wield may be extinguished as the heat produced-by the burning vapor is suflicient4 tocontinue the vaporization of the duid. Thefiamecf theauxiliary wickis extinguished by raising the extinguishing tube sufficiently to inclose the upper end of said wick,as shown by full linesv in Fig. 2. When it is desired to extinguish the main flame, the extinguishing tube is raised until its upper end comes in contact with and is closed by the flange of the cap'D, as shown by dotted lines inFig. 2, whereby the supply of air to the lamp is cnt off. The upper end of the extinguishing tube is preferably dared and made of the proper diameter toreceive the flange o f said cap. Either the auxiliary flame or both the, latter and the main ame may thus be readily 'extinguished by simply turning the operating or less portion ofthe flame.

I claiml as my invention# .v ,1. .The combination with the central'wick tube provided at its upper end vwith a flanged 'cap with a number ofperforations foil the esk' cape of the vapor, of an auxiliary wick sur-" rounding the maimwcl tube below said perf?.4 forations, and a verticiailly` movable extin-,
