LANTERN Application filed Octbber '23, 1928. serial no. 314,3a7.

This invention relates to lanterns, and has for an object to provide an improved lantern in which complete combustion of various grades of fuel may be obtained without 5 smoking.

Another object of the invention is to provide an improved lantern of the type havi'nga globe confinedto its seat by a movable chimney or "flue element, in which the due element may be adjusted to vary theeifective length of the flue thereof and permit use of the lantern with different grades of'fuel oil; in Which the adjustment of the effective length of the flue may be made independently of the movement ofthe flue element as aunit to release or "engage the globe; in Which the sections of the flueelement may be secured releasably in different adjusted positions; in which the flue element may be operated as a unit torelease or grip the globe while in all adjusted positions; in which disengagement of the flue element or any section thereof from the frame of the lantern will be prevented 'yivhen said flue element is released in the absence of a globe from its seat.

Another object of the invention is to provide an improved lantern which will be exceptionally compact for shipping purposesand in which the flue or chimney eleinent may be varied in length to provide the necessary and suitable draft when the lanter'i'i is used for burning various different grades of fuel oil, and in which unintentional changes in the flue length may be prevented.

Another object of the invention is to provide an improved lantern construction Which will accomplish each and all of the above objects. and whichwill be relatively simple, durable, compact and inexpensive. 7

Various other ob 'ects and advantages will appear from the following description of two embodiments of the invention, and the novel features will be particularly pointed out hereinafter in the appended claims.

In the accompanying drawing Fig. l is a side elevation of a lantern constructed in accordance With this invention, withthe flue element shown by full lines in n adjusted posi 1- 1byd sh.l nesininr other adjusted position;

in j

Fig. 6 is an elevation partly in section of a lant'ei n also constructed in accordance with the invention, but illustrating a slightly difteem embodiment of the invention"; and

Fig. 7 is a sectional plan of the same with the section taken ap proximatelyalong the line 77 of Fig. :6. V

In the embodiment of the invention illustrated in Figs. 1 to 5, the lantern has any suitable or usual oil fount and base 1, and tubular frame members 2 extend upwardly from the {base and support a hell. or chimney guard 3. 'll'i'e'base 1 mounts a burner box 4 upon which is'seated a globe plate or seat 5, which plate may be elevated or lowered by the usual globe plate operating lever 6.

.L" transparent globe 7 is demountal'ily supported upon the globe plate or seat 5 between the tubular frame members 2, and the globe terminates at its open upper end below the bell or chimney guard 3. The guard 3, which is tubular, may be open at both ends, and at its upper end has an intnrned flange S. A cylindrical guide or 0011:11 9 is mounted in the interior of the chimney gain-d 3 below the inturned flange 8,-extends in a direction en dwise of the guard, and terminates at its lower end in an inun-nednange 10. v

A fine element 11 passes through the guard 3 and is formed of two telescopic sections 11a and 11? and the smaller or inner section 11aeXt'ending upwardly through and sliding in the aperture formed by the flange 8, and the larger orouters'ection 11.?) extending throughand being slidingl'y mounted in he: 9- t V The lower section 115, acent its upper end, is reduced in diameter so as to provide a shoulder 19, and the extreme upper or reduced end 13 fits and slides upon the outer periphery of the inner or upper section 11a. The larger end or portion of the lower section 111), at a point adjacent the shoulder 12, is provided vith an externally projecting peripheral bead ll, which may be spun therein, that slides along the inner cylindrical wall of the collar or guide 9. The bead 14-, by engaging with the inturned flange 10 of the guide 5), limits downward movement of the lower section 11/) of the flue element and thus prevents disenga ement ot the section 11?) from the guide 9.

n helical spring 15 surrounds the upper tion 11/! ot the line element, and is compressed between the flange 8 oi? the guard and the shoulder 12 on the lower section 117) ot the line element, so as to urge the lower section 117) yieldingly in a. downward direction through the guide 5).

The lower end of the section 11?) of the flue elementtits over a reduced upper end of the globe 7 to hold the globe upright and form a continuation of the flue of the globe for conducting away gases of combustion and providing the necessary chimney action or draft for the purposes of combustion of the flame within the globe.

The lower end of the upper or inner section 11a is provided with an outward y extending flange 16 which closely approaches the inner periphery of the larger portion of the lower section 116, so that flue gases rising from the globe T will be conducted upwardly through the upper or inner section 11a of the flue element. The upper end of the section 11a of the [Inc element may also be provided with a peripherally projecting head 17, that may be spun therein if desired, which may engage with the outer end face of the flange 8 to limit downward movement of the upper section ol? the line element. The flue element at its upper end may have the usual vent apertures 18, and a dome or cap 19 carrying the finger piece .20 which the flue element may be shifted upwardly to release the globe 7.

One of the sect-ions ot the flue element 11, such as the upper or inner section 11a, is provided in the overlapping portion of the telescoping sections, with one or more slots 21, each of which extends endwise ot the flue element for some distance and terminates in or opens into lateral branches 22. A pin 23 is carried by the reduced end 13 of the other section 11?) and projects through the slot 21.

This pin 23, when in the vertical or endwise stretch of the slot 21, permits free endwise relative movements of the two flue sections 11a and 11?), to an extent permitted by the engagementof the pin with the ends of the endwise stretch and in alignment with the end lateral branches 22 of the slot.

Thus the flue element may have its eflecti ve length, that is, the eltective length of the passage or flue thereof, lengthened or short ened by relative endwise movements of the sections. lVhen the effective length of the element is increased, the length of the flue producing a draft in the globe 7 will be increased, and the lantern will burn without smoking, the relatively heavy or crude fuel oils which may be encountered. When the efl'ective length 01"? the flue element is shortened, such as by moving the upper section 11a downwardly into the lower section 11?), as shown in Figs. 1 and 3, the length of the flue passage connected to the upper end of the globe 7 will be shortened, and the lantern will function properly without smoking while burning the higher or better grades of fuel oil. I

By slightly rotating one of the sections, such as the upper section 11a, relatively to the lower section 111), the pin 23 may enter one oi the lateral. branches 22, and while in that lateral. branch, it will releasably lock the two flue sections together, so that they may be shifted together vertically as a unit to engage with or release the upper end of the globe 7.

The flue element 11 will be yieldingly urged downwardly by the spring 15, and this spring will yield when the flue element is drawn upwardly by the linger piece 20 to release the globe 7, and also when the globe 7 is elevated by levers 6 for the purpose of lighting the burner. If the globe should be removed, and the flue element then released, the spring 15 will urge the flue elementdownwardly until stopped by the engagement of the head 14 with the flange 10, the bead 1 1 and flange 10 serving as cooperating steps or abutments to limit this downward movement of the flue or chimney element. The flue elements 110, and 111) may be provided with suitable ventilating apertures as usual in the art, but such apertures per se form no part of the present invention, and perform their usual function.

The embodiment of the invention illustrated in Figs. (5 and T is substantially identical to this extent with the embodiment ill ustrated in Figs. 1 to 5 and simila r parts are designated by similar reference cha actors. In Figs. 1 to two sets of slots 21 and 22 may be provided upon diametrically opposite sides of the flue element, and the pins 23 may he the inturned or angular ends ot a seniicircular spring arm 24- which rests upon the shoulder 12 of the lower flue section. The free ends of arm 24 may be sprung apart, inserted in suitable apertures in the reduced end 13 of the flue element. and allowed to enter the slots 21 and 22. The pins 23 are therefore the angular terminals of the semi-circular spring arm or strip 24, and the two flue sections may be quickly released by merely springing apart the free ends ot: the

lll)

strip or arms 2%, to carry the pins 23 out of the slots 21 and v v In Figs. 6 and 7, the pin is foi-inedby an inturned or angular end "of the spring 15. The pin -93 may be shifted out of interlocking engagement with the se'ctions'of the hue element by merely springing outward the lower end or terminal oi the spring 1-5, and obviously this pin -3 operates in only one slot The use or operation, however, of the lai'it'ern is the same in both embodii'nents of the'invention.

The vertical or endwis'e slots :21 may obviously have as many lateral branches 22 as may be desired into which the pins 2;) may be shifted, so as to lock the flue element sections in di-iferent telescopic or adjusted positionsby the limited relative rotary movement of the telescopic sections. Thus the effective length of the fiueelem'ent which serves as a chimney may be made selectively adjustable in length or height, and may be adjusted by the user until it is suitable for the u'ali ty of oil that is being burned.

The fine elei'ne'nt may also be shortened, that is, the extent to which it projects above the chimney guard '3 may be decreased, so that it may be packed in a relativelysmall box or carton, which greatly reduces the freight charges and the cost of packing, and this is an important advantage in shipments to distantpoints. T he tine element never becomes disengaged fronr'the chimney guard, even when released in the absence of the globe 7. The adjustment of the flue element or chimney may easily be learned by relatively ignorant or unskilled persons, and WitlTOl'lt any extended or specialtraining.

It will be obvious that various cl-iangcr in the details, which have been herein described and illustrated in order to explain the nature of the invention, may be made by those skilled in the art within the rinciple an d scope of the invention as expressed in the appended claims.
