SPECIFICATION forming part of Letters Patent No. 733,106, dated July 7, 1903. Application led February 6, ,1903i Serial No. 142,138. (No model.)

To all whom it may concern: u k tubular stem e and secured to the Wick-tube a Be it known that I, CHARLES E. WIRTH, a and coming at opposite sides of the pinion e.

citizen of the United States,residing at W'ater- Within the tubular stem c and extending bury, in the county of New Haven and State from end to end thereof is a shaft f,\on the 5 of Connecticut, have invented an Improve` inner end of which is secured a tooth f, while 5 5 ment in Wick-Raisers,of which the following on the outer end of the said shaft f is a'nut isa specification. p f2.

Consequently when the 7o Tack-and-pinion device, especially with the nut is clamped in position the tubular stem upward movement of the Wick, and which de-` and the shaft turn together. vice is adjustable for regulating the extent To adjust the wick, the nut is loosened and `of this upward movement. k the tubular stem c turned` to elevate the My invention` is represented Vby several wick to a position where the Haine may burn 75 forms, the details of which are hereinafter without smoking.

The wick-raiser outer surface oi' the wick and the prongs comprises the perforated tubel d, having octhereof to engage the same. i This band h is 95 casional inturned prongs at the respective provided with an interiorly-threaded portion, ends;` the pinion c, meshing with a line of perthrough which the screw-rod l0 passes, the forations of the tube d; the tubular stem e', lower end of said rod l0 passing through an and the knurled disk e2 on the end of said tubuaperture in the bracket 3. 5o lar stem, there being brackets 2, receiving the I provide a casing t' of sheet metal connected Ioo by screws 4 to the upper end of the oil-font, and upon a flat surface provided therefor and adjacent thereto the oil-,font is provided with a guide-tube 5. The screw-rod 10 passes through the guide-tube 5 'and through a sleeve 11 and'through a rack-tube 9, the sleeve 11 being fixed to the screw-rod 10 and the rack-tube 9 rectangular in. cross-section and passing through a corresponding opening in the case. Above said rack-tube, secured to the threaded end of the rod 10, is a head 12. Within the case c' is a pinion 6, meshing with the rack-tube 9. Said pinion is upon a stem 7, the free Iend of which is provided with a knurled disk S outside the case. The rotation of the pinion 6 by the knurled disk 8 moves the rack-tube 9, sleeve 11, head 12, and the screw-rod 10 down and up with a vertical movement and with said movement lowering and raising the band h, pronged arms h, and the wick g, the sleeve 11 forming a stop for the upward movement in the position Fig. 5 and the head 12, coming against the exterior of the casing z', a stop for the downward movement of the parts.

The head 12, screwed upon the upper end of the rod 10, is free from the rack-tube 9,`

there being a slight play, so that by turning the head 12 the screw-rod and sleeve 11 may be rotated, said rod turning in the interiorlythreaded hub portion ofA the band h to raise or lower the band, the pronged arms h', and the wick g and adjust the height ofthe wick with reference to the position of the racktube 9, so as to bring the wick when fully elevated at the proper height for a smokeless iiame, the wick when depressed by the movement of said parts going sufficiently low within the wick-tube a/ to insure the llame going out.

I have shown and preferably employ a friction-spring 13 (see Fig. 5) in the form ofa bent wire, the free ends of which grasp the stem 7; but this device being old in the art forms no part of my invention.

In the form of my invention shown in Figs. 7 and 8, k represents the font for the burning iiuid; c2, the central-draft tube; g, the wick; Z, aband surrounding the wick and secured thereto by a device like the pronged arms 71, Figs. 4 and 5, or by any equivalent structure, and m is a bracket engaging the band Z. tically-placed tube n, extending from near the base of the font up within the same and above the font, and with an auxiliary tube n in the upper end of the font-concentric and surrounding the upper end of the tube n. In the annular space between the tubes n and n there is a tube o, secured at its lower end to the bracket m and normally extending above the upper ends of the tubes n n. The upper end of the tube o is closed except for an opening providing for the threaded upper end of the screw rack-rod o", which passes through and substantially iills the tube n. A knob 14 is on the upper end of The font 7s is provided with a ver-V this screw rack-rod?n and a similar knob on the lower end. r1`he rod r passes out of the lower end of the tube n and through a casing fi', similar to the casing z', (shown in Figs. 4 and 5,) but inverted in its position, said casing being secured to the lower portion of the font by screws 15. A stem 17 passes through this casing, and on one end thereof is a pinion 16, engaging the rack-teeth of the rod r I and on the other and outer end a knurled disk 18, by the turning of which with said stem and pinion the screw rack-rod r is raised and lowered. s is a nut adjustable longitudinally upon the screw-rod r.

'Ihe position of the parts Figs. 7 and 8 represents the extreme upward movement in which the nut s comes against the lower end of the casing fr" and in which position the wick is supposed to be at the proper height for a smokeless iiame. With the movement of the parts and the descent of the rod a" the wick is lowered, and the limit of the downward movement is determined by the inner upper end of the tube o coming against the fixed upper end of the tube fn. As the wick burns and it becomes necessary to increase the height of the same the nut s is rotated on the rod r and lowered. This when the parts are returned to the position Figs. 7 and 8 permits the wick to be raised to the former height and to the required or proper height for producing a smokeless iiame.

The several forms of my invention illustrated embrace a device capable of arresting the movement of the rack-and-pinion device, so as to regulate the opposite movements of the wick, and also a device having an adjustable feature for regulating the extent of the upward movement of the wick.

I claim as my invention- 1. In a wick-raiser the combination with a rack and pinion; of a device coacting therewith and adjustable so as to bring the wick to the desired or predetermined position according to the height of the flame required, the adjustable function being performedwhen the rack-and-pinion device are at an extreme of theirl movement.

2. In a wick-raiser, the combination with a rack and pinion, of a part passing through a part thereof and having a regulatable function, and associated means for limiting the upward and downward movement of the wick.

3. In a wick-raiser, the combination with a rack and pinion, of a vertically-movable screwrod, a part connected thereto and movable therewith and adapted to engage the wick so that the wick is caused to rise and fall with the vertical movement of said screw-rod, and means associated therewith for limiting the extremes of this movement in opposite directions.

4. In a wick-raiser-the combination with a rack and pinion, of a screw-rod passing vertically through the font, a guide therefor con-` nected to the font, a case through which the screw-rod passes, the rack of the rack-and- IOO IIO

5. In a wick-raiser, the combination with the oil-font and a guide-tube carried thereby and extending within the font, of a casing, and

disk for turning the same, a rack engaged by said pinion, and a vertically-movable screwl rod associated therewith, devices connected 6. In a wick-raiser, the combination with the u oil-font and a guide-tube carried thereby and extending within the font, of a casing, and means for securing the same to the font, a

pinion within the casing, a stem and aknurled disk for turning the same, a screw-rod passing vertically within the font through said case and guide-tube, a rack-tube surrounding said screw-rod and engaged by the pinion, a sleeve secured to said screw-rod at one end of the rack-tube, and a head secured to the upper end of said screw-rod above said racktube, and by means of which head the screwrod is rotated, a band having an interiorlythreaded hub portion through which said screw-rod passes, and devices connected to the band for engaging the wick whereby with the rotation of the screw-rod the band and the wick connected thereto are raised andlowered.
