Be itk own that L-WiAIiREN McA'nTnUn Improvement in'Tubular Lanterns, of which I the following is a specification This invention relatesto a burner structure for tubular lanterns in which the wick tube is permanently secured. in place ontho oil pot, asdistinguished. from structures in which the wick tube forms part of a burner whichis removably seated in a socket in the The. objectof thisinvention is to provide asimple, durable and compact structure by which the parts are securely held in position and the escape of, oilfrom thewick tube to the outsideof the lantern'is prevented.v

In the accompanying. drawings: Figure l is, anelevation of the oil pot and connecting parts of a tubular lantern embodying. this improvement. Fig, 2. is a fragmentary top plan view of the. same onan enlarged scale. Fig: ,3 isan elevation; of the burner cone and globe plate. Fig. 4 is. a vertical section-ofthe upper part of the oil pot and theair chamber thereon on an enlarged scale. Fig. 5is a detached sectional elevation of the wick tube and connecting parts at rightfangles to Fig. 4.1. Fig. 6 is a detached elevation of the cup onl'which the wick tube is supported at right angles. to Fig. 5. Fig. 7 isa fragmentary elevation of the air chamber. Fig. 8 is a fragmentary vertical section illustrating a modified connection of. the cup with the bottom of the air chamber. Fig. 9 is a fragmentary vertical section showing a modified embodiment of the. invention.

Like reference characters refer to like parts in the several figures.

Referring. to Figs. l' 7 A. represents the oil pot havi'ng aperipheral walllO and an .oval annular top plate 11' terminating in an upstanding collar 12. The peripheral. wall andthe topplate are preferably formed. one piece in the usual manner... lgo repres sentsv an annular diaphragm or transverse .por-

tionlof the peripheral wall bysolderingand which ,forms i the. top 3 of the oil pot and: the

bottom of the chamber B on the same,

the top of the airchamber being formed by the oval top plate 11. 14 represents the tubes; whlcharesecured to the oval top plate in the; usual .manner. T

15 represents a cup-shapedguard which is secured in the centralopening of the diaphragm 13,,and 16 represents the Wick tube whichissecured .atits lower, end in the bottom pf-this, cup. 17 represents-the wickraiser shaft which is I arranged in notches '18 in the upper edge of this cup and in notches 19 in thecollar 12. ;The opening in the top plate 1 1 which is. surrounded by the collar 12 is covered by a perforated platev 20 which is seated with its .downwardlv turned-margi nal portion upon. the collar 12 and which may be permanently secured thereto, The wick tube extends upwardly through an oblong opening21in the plate 20 and the latter is preferably provided in this opening with lips 210 Figs. 2 4 and 9, which bear along the; tube and into the cup from which such oil can. return into .the .wick tube throughv an opening 22 formed near the lower endof the wick'tube. The lips 210 of the perforated plate, are preferably bent downwardly, as indicated in Figs. 4 and 9 topreventoilwhich flows down on the outer side of the wick tube from passing outwardly upon the perforated plate.

23 ,repr.esents the wick .raiser or ratchet wheels and 24. represents the upright slots formed iinthje wick tube for the same. Any oilwhich escapes through these slots passes into the cup and from thelatter throughthe opening 22 backinto the wick tube and the oil'pot, The cup prevents any oil which escapes from the wick tube from passing into.thefairchamber. andforms an oil guard located between the air chamber and the drainage opening 22 through which the oil is returned to the oil pot. If any oil should flow along the wick-raiser shaft it is stripped from the shaft by contact with the upper portion of the cup and caused to flow down on the inner side of the cup.

The cup may be secured to the diaphragm 13 by soldering or by clenching the bottom of the cup against the underside of the diaphragm, as represented in Fig. 8.

25 represents the burner cone which is separate from the wick tube and is preferably secured to the globe plate 26 in a well known manner.

In the construction represented in Fig. 9, the air chamber D is separate from the oil pot and is of cup shape, having a bottom 26 resting upon the top plate 27 of the oil pot. The bottom 26 and the top plate 27 are provided with coinciding central openings in which the cup or guard 15 is secured. The perforated top plate 28 through which the wick tube projects is provided with an imperforate marginal portion 29 which forms the top of the air chamber.

The drainage opening can be formed in the bottom of the cup instead of the wick tube, as represented at 80 in Fig. 9, but this is less desirable because when the opening is formed in the wick tube there is less likelihood of oil being splashed from the oil pot into the cup by violent movements of the lantern.

I claim as my invention:

1. The combination with an oil pot and an air chamber upon the same, of a wick tube permanently connected with said pot, a guard which, surrounds the wick tube within the air chamber and is permanently connected with said oil pot and said wick tube, and an oil drainage opening arranged inside of said guard and leading from the lower portion of the air chamber to the oil 2.
