N t. 815,834. j

To a/ZZ whom t may concern,.- Be it known that I, ALONZO ABNERWAR- NER, a citizen of the United States, residing at alcohol-lamps; and the objects of my improvements aresirnplicity and economy in construction and'convenience and efficiency 4in operation, particularly with reference to great heating. capacity.`

In the accompanying drawings, Figure 1 is4 'a plan view of my lamp. Fig.A 2 is a sectional .view ofthe same on the line ma of Fig. 1. Fig.

3 is a detached side elevation of the upper end of the wick-tube. Fig. 4 is an enlarged sectional elevation of the shutter-raising devices as detached lfrom .the lam -font.

A designates the font, whic Y may in the main be of any ordinary construction. To the bottom 5, on the inside, I secure a nut 6, that is slightly elevated above the bottom, so that the alcohol or other vapor'generating iiuid in the lamp may pass under it and into its interior from the lower end. As shown, this nut is elevated by being seated on two small'elevations7 7., that are swaged or struck pp in the metal that forms the bottom of the place by screwing it into the nut 6. The upper end 'of the 'wick-tube is vclosed lin any proper manner-as, for example, by an im- .perforate cap 9 with a iiange 1() at the junction of the tube and cap. Below this flange there are two hollow peripheral beads 11, made by an enlargement of the tube at these v points, leaving the metal ofthe tube of a uniform thickness throughout. 'For convenience of illustration the thicknessof the metal` in thetube 8 is represented thickerthan itmain part of the burner, is filled from end to4 end with a suitable wick or wicking 13. It Should be noted that the wicking extends The wick-tube 8 is screw-threaded at its lower end, so that it may be secured in i Specification of Letters Patent.1 A Application mea Juiyiz, 1905. sannita 269,385.

considerablyabove the u -permost series of jets or uppermost exit of t e'wick-tube.

The' top of the font is provided with'a fixed n guide-'tube 25, concentric with the wick-tube,

and between the guide-tube and the wick-v tubethere is a rising-and-falling .tubular shutter or flame-extinguisher 24. Thebody of' this shutter is of a size'to readily pass over the beads 11, and its upper end is provided with an outturned or funnel-shaped flange 14, with a series of swa'ged jet-recesses 15. The shutter is raised and lowered by an operatingshaft 16, pinion 17, and a series Ofperforations 18 in the shutter, which perforations act as a rack in connection with the said pinion. The operating-shaft is mounted in a bearinglQ, stufIing-box 20, and nut 21, the said shaftfhaving a bead or shoulder 22 between the shoulder in the stuiiing-box and the 'endof the nut, which shoulder prevents the said shaft from moving longitudinally inward, while the pinion 17 on the inner end of the said shaft prevents longitudinal movement in the opposite direction. Any suitable knob or handle 23`may be provided for convenience of rotating the shaft.

When the shutter 24 is lowered to bring its enough, as show n in Fig. 2 to cut off and ex- 90. lesser heat the shutter may be turned up farl tinguish'the iiame in the lower series of jets. v

For a still lesser heat or a low heat the shutter'mayhbe turned up until it is stopped'v by.

the iiange 10. This will extinguish the flame from the upper series of jets, but the gas will `still flow through the jets up through the shutter and out at the recesses 15 in the iiange 14, where it will burn in as many jets as there are recesses in the said flange.

Provision for the gas to flow upwardly and out at the jet-recesses in the shutter is had byl leaving a suitable space between the shutter and wick tube. As shown, the 'shutter is straight-sided and the wick-tube is beaded, so thatv there is ample space for the gas to flow upwardly through the shutter after it passes loo` the upper bead. I prefer to t the shutter so close y to the beads as to substantially cut off the upward flow of -gas from below the upper bead and to form the perforations in the said upper bead so far above the greatest diameter of the said bead as to carry them away from the inner wall of the shutter, so that gas will flow upwardly therefrom even when the shutter closes tightly on the bead. The jetperforations in all of the beads are preferably made a little above the greatest projection or diameter of the said beads, so as to direct the flame or et issuing therefrom slightly upward.

By having an imperforate top to the wicktube and having the absorbent wick extend up above the highest exit in the said tube the alcohol is carried up above the said exit, where it is heated and gas generated that flows downwardly and out at the exits. This results in an ample supply of gas for a large number of jets. A priming-wick or primingperforations for starting the iiame are not necessary, but their presence or absence would not change the construction hereinbeforedescribed. With the hollow beads in the wick-tube and only iine perforations or jets the wick is held somewhat away from the jets, as shown in Fig. 2, and the perforations are so small that the iiame is substantially all on the outside of the wick-tube, whereby there is but little consumption of the wick when the font is properly supplied with alcohol.

I am aware that vapor-lamps have been made with wick-tubes supplied with wicks and fine exits forming gas-jets in or leading from the said wick-tubes and also with tubular shutters having a movement relatively to the wick-tube, and I hereby disclaim the same.

It is apparent that some changes from the specific construction herein disclosed may be made, and therefore I do not wish to be understood as limiting myself to the precise form of construction shown and described, but desire the liberty to make such changes in working my invention as may fairly come within the spirit and scope of the same.

I claim as my invention- 1. In a vapor-lamp, the combination of a font with a wick-tube having a hanged upper end, and a plurality of peripheral beads each with a series of perforations, the said perforations in the upper one ofthe said beads being slightly above the greatest diameter of the said bead, and a shutter having a relative longitudinal movement with the tube and its inner diameter of a size to pass over and closely fit the said upper bead so as to substantially close the space between the -wiektube and the shutter.

2. In a vapor-lamp, the combination of a font with a wick-tube having an iniperforate upper end and a series of fine perforations below the said upper end, and a tubular shuttervhaving a fianged upper end with jet-recesses formed therein, the said wick-tube and shutter having a relative longitudinal movement for covering and uncovering the said perforations, and also having provision for gas to iow upwardly from the said perforations through the said shutter and out at the jet-recesses for burning at the said recesses when the shutter extinguishes the flame at the said perforations.

3. In a vapor-lamp, the combination of a font with a wick-tube having an imperforate upper end, astop-flange at the said upper end, and a hollow peripheral bead with iine perforations therein at a point below the said flange, and a shutter movable longitudinally relatively to the said wick-tube and having a body for covering and uncovering the said bead, and a ilanged upper end with jet-recesses formed therein, the said 'flanged u per end being arranged to close against t 1e flange of the said Wick-tube.

4. In a vapor-lamp, the combination of a font with a wick-tube having a flanged upper end and a peripheral bead provided with a 'series of j et-perforations, and a shutter having a relative longitudinal movement with the tube and its inner diameter of a size to pass over the said bead to extinguish the iiame thereat, and jet-openings at the upper end of the said tube and shutter which remain open when the shutter is fully closed; the inclosing walls of the said jet-openings being formed partly by the said wick-tube and partly by the said shutter.
