VAPOR-LAMP.

Patented July 17, 1906.

To all whom it may concern:

Be it known that I, ALONZO A. WARNER, a

. citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Vapor-Lamps, of which the following is a specification.

My invention relates to improvements in vapor-lamps; and the objects of my improvement are simplicity and economy in construction and convenience and efficiency in use.

In the accompanying drawings, Figure 1 is a central vertical section of my lamp on a line transversely to the axis of the pinion which operates the shutter. Fig. 2 is a detached side elevation of the burner or wicktube.

A designates the font, having a fixed guidetube 3 in the center of its tog), inside of which guide-tube the shutter 4is fitted to move up and down as the pinion 5 and its shaft 6 are rotated. A row of perforations 7 in the side of the shutter serve as a rack for the said pinion to engage. In the bottom of the font A two or more elevations 8 are formed, upon which to mount the fixed nut 9, so that the fluid within the lamp-font can enter the inner side of the nut by flowing in between the elevations 8. Thelower end of the wick-tube 1() ridi* of which fits the nut E), so that the removable wick-tube can be inserted and held in place by screwing the lower end into the nut and removed by unscrewing the said threaded end from the nut. wick-tube that screws into a nut in the bottom of the font is old; but in the present case the thread is rolled in the metal so as to form a thread both on the outside and inside of the wick-tube. This thread is carried up on the wick-tube a little higher than the main part of the top of the font and is therefore extended to a point above the intended fiuid-level of the font. The tube is filled with a subtos, thesize and hardness of the wick being such that it rests on the innermost projections of the female thread inside of the wicktube and leaves the groove of the thread open, as shown, whereby the fluid in the font may fiow upwardly in this thread or spiral passage and keep the wick wet up to the level of the fiuid inthe font, whereby the lamp is more eective than it would be if it had to draw A removable the fiuid up from a lower level. This is especially the case with an asbestos wick, which is not quite so absorbent asa cotton or other ordinary wick. j

The body of the wick-tube is of a smaller diameter than the shutter; but its upper end is provided with two beads or enlargements 13 and 14, the diameter of the wick-tube at the most prominent part of these beads being approximately the same as that of the inner diameter of the shutter 4. In the beads I form the jet-perforations 15, preferably alittle above their summit. The upper end of the wick-tube is closed by a cap 16. A perforated ring 17 is placed on the wick-tube just under the lower bead 14, the exterior diameter of the ring being substantially the same as that of the bead, so that the shutter can pass it, thereby making an annular chamber which is filled with a suitable primingwick 18, preferably of asbestos. The ring 17 may be secured in place in any ordinary manner. As shown, 11 is secured by making a slight swell 19 in the wick-tube just below the ring. I prefer to have the wick 12 at its upper end stop short of the lower bead 14, so as to leave an unobstructed gas-chamber 20, Fig. l in the upper end of the wick-tube, and

thereby more nearly equalize the pressure of 1s ;-rovided with a rolled thread 11, the extethe gas that issues from all of the jets.

F or starting the lamp the shutter may be turned up to its full height and the lamp shaken a little to throw some of the alcohol up inside of the shutter and saturate the priming-wick 18. The shutter may then be turned down to the position shown in Fig. 1, or a little lower, so as to ex"ose the perforations in the ring 17 and the mclosed primingwick, which may be lighted with a match. In a short time ,the lamp will be hot enou h to generate gas, which will come out at the jets and be ignited. The shutter may then be turned up far enough to extinguish the A flame at the ring 17, while it still issues from stantially round wick 12, preferably of asbesboth rows of jets. The flame at the lower row of jets may be extinguished at any time IOO desired by raising the shutter so as to close and it is applied at a small oost with none of the disadvanta es of an outer wick that exterds substantially the length of the wiektu ej I claim as my invention- 1. In a va or-lamp, the combination of a lam -font with a iixed nut on the inside at the ibottom of the said font, the interior of the said nut communicating throughits lower end with the said font, a removable wicktube having a rolled thread at its lower end whereby the said lower end is both exteriorly and interiorly threaded, and a wick within the said tube bearing on the inward projections of the inner thread at the lower end of the said tube, leaving a spiral passage around the wick inside the lower end of the said tube for the fluid in the font to pass upwardly through from the lower end of the said nut to the fluid-level of the font.

2. In a vapor-lamp, the combination of a wick-tube having jet-perforations atits upper end with a erforated ring mounted on the said tube be ow the said jet-perforations for forming an annulanwiok-chamber inside of the said ring and outside of the said wicktube, a priming-wick within the said chamber, and a shutter surrounding the Wick-tube and adapted to close over the said ring Yand jets.
