Specification of Letters Patent. Patent d Sept. 13, 1921.

Application filed October 2a, 1921 Serial 110. 419,642.

To all whom it may concemv Be it known that I, Monnsrn BOILEAU, a

citizen of the French Republic, and resident of Suancourtpar Morey, Haute Sane, France, have invented certain new and useful Improvements in Adjustable Wick-Carr iers, of which the following is a specification.

The present invention relates to a device for regulating the wicks of night lamps whereby the length of the wick may be proportionate to the depth of the oil recipient and to the height of the oil contained therein.

Furthermore the novel device has the advantage that, the wick may be of a convenient length, and that it shall not be necessary to frequently replace the wick by a new one, as it was the case until now. A wick is Wholl burnt away.

The evice is formed substantially of a slotted tube within which is rotary mounted a threaded spindle by a correspondingl threaded sleeve on which is secured the wic carrier proper, projecting through the longitudinal slot provided on the tube and provided at its free end with a resilient sleeve into which is inserted the wick.

It may be understood that, when suspending the said tube by any convenient hanger on the edge of the oil container, whereby the tube dips into the oil, the wick, maintained on its carrier, may be moved together with the latter in a vertical direction within the oil by rotating the threaded spindle.

The time during which the wick burns, depends on the length of the wick portion above the oil. By rotating the spindle, the wick, together with the carrier, may be raised to the required height within the oil.

In order that the invention may be readily understood,it is shown by way of example in the accompanying drawing in which:

Figure 1 is an axial section through a lamp carrying the device, while Fig. 2 is a top plan view of same; and

Fig. 3 is a front view of the wick carrier pro er.

he device is shown in a working position within an oil container.

The regulating device comprises a tube 1 provided with a longitudinal slot 2 extendin through substantially the whole tube. Wdthin the tube 1 is axially engaged a threadedspindle 3 rotatingly mounted in the tube and provided at its ends with caps or knobs 4, the upper knob serving for rotating the spindle 3. A threaded sleeve 6 forming a nut or female part on said spindle 3 within tube 1 is provided with a rod 8, projecting at a right angle from the spindle through the slot 2. Said rod carries at its opposite end a resilient slotted sleeve 10 intended for carrying the wick 9.

When the cap 4 is operated, the spindle 3 rotates and the sleeve 6, applied against one edg of the slot 2, moves in a vertlcal direction according to the direction of motion imparted to the spindle.

The device is provided with suspension means 11 for suspending same on the edge of the oil container. These means are formed for instance by a clasp made of a thin strip of resilient metal conveniently folded in she e of a sleeve, clasped around the tube 1 at 7 and the folded wings or free ends 11 of which engage the edge of the container 5.

The length of the wick 9 depends from the size of the container and the height of the oil within the container.

The height of the wick above the level of the oil may be regulated at will, according to the space of time during which it is desired to have the lamp lighting.

For putting out the lamp, it suffices to blow the flame or to lower the wick by operating the knob 4 until it is wholly dipped into the oil. For lighting it again, the wick is raised above the level of the oil at the de sired height.

An vessel may be used as oil container. It is owever convenient to make use of a vessel of such dimensions that, when the device is suspended by clasp 11 on the edge of the container, the wick is substantially in the central axis of same. The tube 1 should not extend downwardly far enough for reaching the bottom of the container. On the other hand, the upper cap 1 should always project above the edge of the container, in order to make the operating easy.

The wick is engaged into the resilient slotted sleeve 10 which grips the same between-its jaws, thus maintaining it firmly.

From the foregoing description it will be readily seen that I have produced a device as substantially fulfils the objects of the invention as set forth.

Having now fullyvdescribed my said invention, what I claim and desire to secure by Letters Patent, is: r

A wick carrier forcooperation with a ves- 5 sel adapted to contain an inflammable fluid comprising a tube formed with a longitu dinal slot, a threaded rod mounted for rotation within the tube and operable from beyond one end of the tube, an arm having 10 threaded connection with the rod and extend ing laterally of the tube through the slot therein, means on said arm to support a wick, and means slidable on the tube to engage the edge of the vessel to support the tube within and in spaced relation to the vessel.

In testimony whereof I have hereunto set my hand in presence of two witnesses.
