Description

LAMP,IN PARTIC~AR TA~LE LAMP

The invention relates to a lamp and ln particular a table lamp which comprlses a holder, a llght source mounted on thl3 holder and a shield for the llght source.

Lamps of th~3 kind, for example, storm lanterns, have as a shleld a glass body mounted on the holder, - 10 whlch forms a base, and the shleld protects a candle, serving as the light source, agalnst the wind. As the glass body reflects the heat radiated by the burning candle and the movement of alr wlthin the glass body 19 weak, the wax ~rom the burning candle generally softens, whlch leads to a premature drlpping of the molten wax and to rapid consumptlon of the candle. To this must be added the fact that the glass body of these known storm lanterns 18 relatlvely expen~lve.
Storm lanterns are used prlmarlly ln the open alr, where value 19 put on the fact that a candle cannot be extingulshed by the alr currents prevalllng under those condltions.

on the other hand hollow-burnlng candles are known, in whlch wax, wlck and diameter are related to one another in such a way that the candle burns down more or less only ln the centre and accordlngly a ~ ~ -sleeve or shield of wax remains standlng. The combustlon ln such candles i8 poor because the air needed for combustion can only reach the candle through the top openlng. This results ln an unstable flame whlch gives off a lot of soot.

Commercially avallable candles wlth a wick embedded in a body of wax burn down from top to bottom, the wax on the surface of the candle meltlng. The "~,-, i . ~ . , . -, . .

~ thinner or smaller 19 the body of wax ln such candles and the greater the degree of stillness of the air ln the room, t~e better and more trouble-free does the candle burn down, and the smaller is the proportlon of soot occurring on combustion. ~owever as in practice there 18 a certain degree- of m~vement of the air even in a cloRed room, the products of combustion from such candles always contain a propo.~tion of soot which is still significant and damaging to health and which coats the walls of the room and the furniture ln it with a grey film over a long period. A further drawback of candles lies in the fact that the ~urface of the candle, whlch is often formed with a great deal of outlay and artlstic work, burns with lt 80 that the appearance of such candles after a certain period of burning, even when they are not alight, is serlously adversely affected. To this must be added the fact that the volume of ~uch candles becomes smaller as they burn down, 90 that the candles look progresslvely less attractlve.
' :
Flnally candles are also known that give a colored flame. Rowever the colorlng of the flame is only very pale. Moreover unpleasant odors and vapors arlse as they burn.

It ls the ob~ect of the lnventlon to provide a lamp, and ln particular a table lamp, in whlch the light source burning with an open flame and in partlcular a candle serving as the light source burns largely wlthout soot and, independently of burning down of the light source, provides the impresslon as if an open light source is burning like a candle but without becomlng shorter.

- Thls problem i9 solved according to the invention ln a lamp of the kind stated ln the introductlon and having the features of the characterislng part of claim 1. Advantageous embodiments of the inventlon form the subject matter of the subsldiary clalms.

The invention envisages a non-combu~tlble grld of as fine mesh as possible, formed lnto a sleeve which ls for example cylindrical and shaped preferably from non-spun glass sllk or non-spun glass wool ln whlch the lndlvidual flbres are arranged alongslde one another, untwisted, preferably knitted, crocheted, felted or woven ana which advantageously 1~ stiffened by a refractory treatment after production of the grid. The sleeve formed from a grld whlch ln operatlon i9 so-to-speak llt-up or glowlng, receives wlthln lt a light source such as a candle burnlng with an open flame, and the candle can also be made thicker over its lower portlon than the dlameter or outline of the sleeve in plan view. In the last-mentioned case the sleeve i8 not dlrectly mounted on the holder, but can sit with lts lower end resting on the thicker part o the candle and accordingly can form a unit wlth the candle. The grld of the sleeve whlch is llluminated ln operation can also be made decorated and colored and can always be used agaln as it ls neither damaged nor consumed by the flame from the light source.

As a unlform supply of alr ls achieved also from below and from the slde through the grid-like wall of the sleeve surrounding the light source, the flame of the light source such as, for example a candle, burns unlformly, i.e. any flickering and instabillty of the flame is virtually entirely elLminated. Thls leads to clean soot-free combustion. By the size of the openings, for example the mesh of the grid-like wall of ~, :, " ' " ", '' ' ,' ,, ~ " ' ,~. . .- . . , ~

the sleeve, and also by the helght of the sleeve - - ltself, the supply of alr into the lnterlor of the sleeve can be determined or ln fact controlled.

The grid forming the wall of the sleeve ; ~urroundlng the flame from the llght source partially ab~orbs the light rays emerging from the flame, allowlng part. of them to pass through and a further portion of them to be reflected 80 that when the flame 0 i9 burnlng the overall impre~sion i9 given of an llluminated sleeve. What is particularly attractlve to the eye in the lamp according to the inventlon i9 ; that the flame as such i9 not particularly directly visible but that the grid-llke sleeve 18 itself illumlnated overall, and in fact over lts entire height and $ts entire periphery, more or less uniformly, slmllarly to what 19 the case in an electrlc light bulb with a fro~ted translucent glass.
: . :
~oth the llght source such as a candle and also the sleeve which surrounds it could be arranged on a common base, here deflned as a holder, which is made for example of metal, plastics or ceramlc. In such an arrangement the candle can be impaled on a spike mounted on the holder or it can be inserted ln a socket in the holder. The grid-like sleeve ls in thls ca~e fitted onto the halder or the base ln such a way that ~t surrounds the candle, and the outside diameter of the candle can be matched to the inside diameter of the sleeve and thereby the candle and the sleeve can be fltted onto the holder together. ~owever the sleeve preferably has a larger inside diameter than the outside diameter of the light source such a6 a candle, ~o that the llght emitted by the burning flame can light up the sleeve over its entlre height. As the candle burns down any wax which drips from it can be ~ " ,-~ "~ ,", , "

collected by the holder for the candle and the sleeve, 90 that no addltional candle halder i9 needed.

The sleeve can be proflled in plan view and also in longltudinal section, or partially proflled or alternatively can be completely cylindrical and can be produced ln the wldest range o~ sizes. Also a conlcal or frusto-conlcal shape is poss ble, ~ust as all other shapes of hollow bodies which have or allow a decorative form can be envi~aged.

A rigld rlng-shaped mounting can be provlded at both ends of the sleeve, and an annular container of metal, ceramlc or the llke can be mounted on th~ 9 mountlng at the upper end of ths sleeve and is for example filled with glass wool. ~he glass wool can contain a few drops of perfume whlch are continuously vaporised by the heat given off by the burnlng light source. Instead of a perfume, the glass wool can also be soaked in an insecticide.

By means of the ring-shaped mountlng present on the upper end of the sleeve a candle toy or a rotating body can also be mounted on~the lamp according to the invention, for example at Christmas time, and 19 driven by the air rlsing wlthin the grld-shaped sleeve, by means of incllned vanes ln the manner of a wlndmill.
Also the sleeve can be provided with individually openlng small windows on lts outside to form an advent calendar or Chrlstmas calendar.

Although in a first basic em~odiment the light source of the lamp according to the invention can be a commercially available candle burning with an open flame one could instead provide as the light source a commercially available or modl~led nlght light, a ~'''~',' ~;' ,, ,' , ,., . : , .

petroleum ~urner or an oll lamp wlthln the sleeve formed as a llght grld. Uslng such llght sources burnlng wlth an open flame the lamp accordlng to the inventlon agaln glves the impresslon that the llght source mounted ln lt lq a candle, especlally when the sleeve formed by the llght grld is cyllndrlcal or conical ln plan vlew.
, - -A particular feature of the lamp accordlng to the invention lles in the fact that ln operatlon theappearance of the lamp does not alter ln accordance wlth the degree of burnlng-down of the candle mounted ln it. On the contrary the gr~d of the sleeve i8 lllumlnated more or less uniformly, even when the candle 18 nearby burnt down or when usln~ for example a nlght llght as the llght source.

The illumlnated grld ~ormlng the wall of the sleeve 19 preferably made from a tube formed of fabrlc materlal, for example from a non-spun glass silk or non-spun glass wool and is then steeped in a non-combustlble llquid, for example waterglass.
The tube which is made and treated ln thls way 19 drawn over a shape-glvlng mandrel, preferaSly of plastlcs, and ln thls posltlon it is drled. After drying the sleeve is rigid. ~e~ore or after drying the sleeve can be decorated with bands and figures, for example of plastics or metal. After drylng the sleeve i~ taken off the mandrel.
If a coloured verslon of the grld-llke wall of the sleeve 19 wanted, the approprlate dye can be added to the stiffenlng medlum such as the waterglass. The productlon of the grld-shaped tube is easy and cheap to carry out. Sleeves or shields can also be produced in thls way for lamps having electrlc llghts ln them.

, ~','''' '~ '"; ~,"
~'~' " ' ~' '' - ~ The fabrlc material for the grld-shaped sleeve of - the lamp accordlng to the inventlon could however al80 be made of cotton, plastlcs or the llke and stiffened with waterglass, starch, albumen and 80 on, although 5it has be found that currently the best glowtng appearance and total incombu3tiblllty can be achieved with materials such as fabrlcs of glass wool and gla~
sllk.
' 10In any case the material formlng the wall o~ the sleeve should be made of such a coarse mesh that the air which is wanted for uniform combustion can flow into the interior of the ~leeve through the mesh in sufficient quantity. Although it i8 preferable on 15decoratlve grounds to produce the mater~al which form~
the sleeve of the lamp according to the lnvention as a -~
preiabricated tube, thls knitted or woven material can also initially be in the form of a strip which then ha~
its edges brought together to form the desired sleeve 20shape and sewn together or otherwise joined together.
.
~ ' The last-mentioned way of glvlng the shape is of particular advantages where the outline of the sleeve 25is not circular but for example polygonal and in ~-particular toothed or star-shaped.

The lamp accord~ng to the invention 19 a primarily intended for use ln closed spaces, but can however al90 30be used a 6torm lantern out in the open, especially if additional measures are undertaken to keep away from the flame of the burning llght source dlrect gusts of wind or other air movements which can generally be expected out in the open.

:~

, ~- - .

A further possibility for the lamp according to the lnvention lies ln mountlng a small container to receive water on the rinq-shaped mounting present on the upper end of the sleeve. When the source of llght 5 is burning the water evaporates as a result of the heat of combustion acting on the container, 80 that a certain degree of humldifylng of the alr in the room in which the lamp i9 operated car. be produced as well by the lamp according to the inventlon.
,- In order to be able to use the lamp accordlng to the invention also in the open so that the flame of the llght source is sttll reached in sufficient quantlties by the oxygen or air necessary for virtually soot-free combustion, and on the other hand to prevent the flame from belng disturbed by air currents in the surrounding atmosphere, the sleeve which 18 for example cyllndrical or alternatively conlcal can be provlded externally between its upper and lower ends with at least one wind proof surrounding shleld which for example comprises a transparent sheet. The sheet can be rigidly connected to the sleeve or it could be fitted onto lt loosely and accordlngly displacably. In this embodiment of the invention at least at the lowex end of the grid-shaped sleeve a portion remalns uncovered, through which the air necessary for soot-free combustlon can enter in sufficient quantity. Through the upper end of the sleeve, even lf further structures or additional coverings are provided on it, the warm combustion air which rises from the ftame can emerge more or less unhlndered.

Accordln~ to a further feature of the invention the holder formed as a base can ha~e on lts upper face three or more ribs extendlng towards the centre, of which the innermost edges or tips are arranged at a ,,.
~"

, - distance apart such that candles or night llghts o~
different thicknesses fit between them. Wlth a thlck candle having a diameter of, for example, 40mm, lnserted between these ribs there remdins below the candle and on the upper face of the holder a cavlty which provides sufflcient space for any wax which may drip. If on the other hand a thinner candle 1~
inserted between the tlps of other ribs this c~ lty can be smaller or om~tted altogether. ln any event a base of plastics, glas8, metal, porcelain or the like can be provided, and it can be of any deslred shape and slze within the limits determined by the holder.

The covering for the sleeve can also comprise a film of high-temperature-reslstant and non-flammable material, preferably plastics. ~he film can be decoratively printed before assembly and before welding together to form the final shape, if necessary even before cutting.
Wlth the use of candles burning with an open flame in a wind-proof sleeve, l.e. in storm lanterns, dlfficulties arlse through the fact that the temperature in the sleeve increases as a result of reflection of heat and lack of ventilation. This results in disturbance to the normal burnlng-down of the candle designed for normal room temperatures so that it can lead to melting and dripping of the wax material of the candle. Also within the sleeve according to the lnvention wlth a grid-like side wall the temperature does rise somewhat when the flame is burning but less than in a normal storm lantern. It has now been found that the lntroduction of night lights can offset the above-mentioned drawbacks of known storm lanterns, and ~ndeed in partlcular in a lamp according to the invention having a sleeve in the ~ '-' ' ' ' , . .

form of a grld. In addition there 1B the advantage - that ln the use of a stor~ lantern the flame generally practically always burns ln the lower part of the sleeve and not, as in a long candle, lnitially ln the upper part and progressively moves downwards. The drawback of known night lights lies in the fact that these only burn for about four to five hours and their reservolr of wax i8 then used up. ~n order to ellmlnate ~lis drawback, according to a further feature of the lnventio~ there is proposed a specially further-developed nig~t llght which has on it~ lower end a shell or pot of practically the same size as in known night lights, namely for example having a dlameter of 39mm and a height of 18mm. The moulded body of wax provided in this shell or pot is however made at least about twice as blg as in an ordinary ~ight light and has a weight of for example about 30gm which represents a doubllng of the hitherto normal welght of nlght llghts of about 15gm. Over the upper part of the wax body, ln this nlght light accordlng to the invention, there is fitted a rlng, preferably of metal, whlch engages the outside of the wax body and which rests on a small offset heel of the wax body. This ring can, in this arrangement, proiect about 2 to 3 mm into the pot of the night light. It is made with an external conlcal taper of about 1.5 degrees wlth lts taperlng end downwards, matching the conical inside of the shell or pot of the night light.

When thls night light is lit, the wax melts in the upper part of the moulded body and burns over a period of time. When the level of the wax has fallen by a few millimetres after ~ correspondlng period of burning, the heat passes progressively t~rough the heat-conducting rlng to its lower end and thereby i9 conducted to the support point of the rlng, which ~., .,, , :
~,'','. ~' ' ", ~' ' ' ' , ,~,,i . .. .
"~.~,. . . . . .
;, ", , .

,' t,~ r ~:`~S~

causes melting of the wax at this point in the mould~ng, whereby the support for the ring yields and - the rlng accordlngly sinks downwards progressively under lts own weight. Accordingly the flame remalns v~sible even after a long period of burning. ln this arrangement the supply of sufflcient air to the flame ls achleved at all t~mes because the ring in practice moves downwards progressively with the flame. In known simple nlght lights by contrast it ls only true t~at in the final phase of the combustion process, that iq to say when the light is almost burnt out, the flame still burns steadily and does not flicker, and soot ls not produced in excessive quantities. If, on the other hand one were to ~ncreaser the helght of the shell or pot in the known night lights having the same diameter of 25 or indeed 30mm, the flame could no longer burn steadlly because the air required for combustion has to be supplied from above, over the upper rim of the shell or pot. The consequence would be an unsteady flame and a hlgh proportion of soot.

The cover ring to be provided in the night light accordlng to the invention, and sinking as it burns up, can be employed ln many ways, i.e. lt can be fitted onto a new night light according to the inventlon by the user before it is introduced. This not only allows costs to be reduced but also reduces the waste, so that thls solution is environmentally friendly. The ring-shaped cover can be provided with a laterally pro~ectlng tab for extracting it from the ~hell or pot when the nlg~t light i9 burnt out, the tab allowing tllting of the cover rlng whlch ha~ sunk into the shell or pot in order to release it from the solidlfied wax residues.

,i~, ; ,',, ' . , , ' '': .' ' ' : ~ - It 19 also posslble to construct the night light provlded with a slnking ring-shaped cover, speclally for the lamp accordlng to the invention in such a way that the rlng-shaped cover can easlly be freed from the lower shell or lower pot of the night light. For this purpose the shell or pot of the night light i9 made - externally cylindrical a~ in known night lights so that the shell fits exactly onto the holder ~^ lnto a locatlng arrangement provlded there. In thls constructlon there lies underneath the shell, for example, a curved leaf spring whlch holds the shell at such a height that the upper rim of the shell lies at , about the height of the upper rlm of the holder that - receives the shell. When the rlng of the night llght lS together with the level of the wax in it has sunk so i far that lt is received completely within the shell, lts upper rim lies at about the level of the upper rim of the shell and of the holder. When the night light 19 then completely burnt out it is only necessary to push the floor of the shell of the nlght llght further downwards, the leaf sprlng yielding downward~. The , rlng remains hangtng on the holder and is thereby freed from the shell. After removal of the wick-holder a new mouldlng wlth a wick embedded in it can be inserted ln the shell of the night light.

Wlth a night light of thls improved klnd and wlth a wick and with the same size of flame a burning tlme of ten to twelve hour~ can be achieved. Also lt ls possi~le to arrange several covering rings one above another on the outside of a moulded body of wax for the nlght light so that a still longer time burning can be ¦ achieved.

The advantage of such nlght llghts provided with ring-shaped covers lies not lea~t in the fact that no , . . ~ . .. .

drlpplng of wax occurs, one obtains a long burning tlme, the flame 18 always ~lsibls and soot-free combustion 18 achieved.
.
Night lights as l~ght sources for the lamp according to the ln~ention have tAe advantage that the kerosene wax always burns practically wlthout any residue. Any residue of wax or kero~ene remainlng in the shell can burn up as the next wax moulding burns.
: 10 Although lt ls explained earlier that the ring-shaped cover can be provided in a night light with a heightened wax moulding or wax body, it is also posslble to provlde a night light of normal size and shape wlth a cover ring whlch from the start i8 pregent at about the height of the upper rim of the shell or pot of the night light. In this arrangement it preferably projects four or five millimeters above the upper edge of the shell or the pot of the night light. This version has the advantage that even uslng night lights which are commercially available in themselves as light sources, in the displacement of the burning light the wax whlch has melted on the surface - cannot easily spill over. Also thi~ embodiment is of advantage for lamps whlch in some circumstances do not stand on a level surface, for example, when the lamp is used for Chrlstmas tree decoration. It is just in this last-mentioned version of the lamp accordlng to the invention that it can stand in a tilted attitude on a branch of a tree either because of the mounting or through su~sequent alteration of the position of the branch, which , when using normal night lights, can lead to dripping of the wax unless special measures are taken.

As means for retainlng the cover rlng on the - under~lde of the uncovered wax mouldlng of a night llght accordlng to the lnventlon the ring-shaped cover can be provlded on its inner edge with webs whlch, when 5 the cover i9 fitted onto the mouldlng, press into the - wax of lt ln order to achieve the result that the rlng-shaped cover cannot slip downward too rapidly.

The materlal of the ring-shaped cover should be chosen wlth regard to its thermal conductlvity and the dlameter of the shell or the pot of the night llght and the size of the flame and thereby the dlameter of the night llght. Wlth a higher thermal conductlvlty the - rlng sinks more rapidly than with poor conductivlty.
- 15 Also the ring-shaped cover can, in re-usable night - lights, be made of flexible material in order to make it easier to remove from the shell or pot after complete combustion of the wax.
., .
sl 20 Below or on the floor of the shell or the pot a ^ tab can be provided, keeping the residual and generally unburnt wax away from the ring-shaped cover whlch has dropped wlthln the shell. The wick holder of the niqht I llght should be kept vertical ln order to avoid tilting.

~ In order to make the lamps according to the J invention suitable for mounting on the branches of trees such as, for example, Christmas trees, according to a further feature of the inventlon a clip is mounted on the underslde of the holder of the lamp through a ball joint and can be fitted with a spike. The clip is applied to a twig of the fir tree from above, the spi~e penetrating through the twig and thereby preventing any lateral displacement or turning of the clip about the branch. With the help of the ball ~' ~ " ' ~, ' ' , ' .. . .

' 5 -~ Preferably the grid-shaped sleeve in this case is provlded wlth a special cover on its upper end, in which holes are provided for passage of hc~: air. In th~s way the rising hot air becomes mixed with cooler surrounding alr as it emerges from the lamp so that the hot air stream ls damped as it rises and none of the -,' ' hlgher branches of the tree hanging above the lamp can ',~ be set on fire. Also it prevents the pine needles belng able to fall into the lamp and into its light source. The grid-shaped wall of the sleeve prevents '-~ other branches being able to get into the flame.

'l, The origln of fires in Christmas trees often lies ',~ in the fact that above a candle burning with an open ,j 20 flame there 18 a further branch whlch ultimately '~J' catches fire or the pine needles fall onto the candle and there they enter into a combination with the wax of the candle. As the candle burns down the needles , which are thus mixed with wax finally start to burn.
- 25 These origins of fire are eliminated by the lamps according to the invention in the manner descrlbed above. The danger of fire using the lamps according to the invention as Christmas tree decoration is also ', significantly lower beca,use night lights are relatively ~, 30 low in helght in comparison with the normal Christmas ~4 tree candles so that with the lamps according to the invention the flame i~ ~ituated immediately above the associated branch of the Christmas tree on whlch the lamp is secured, and accordingly burns at a greater distance from the branch above.

.

, j . ~ . -, , , ~ .

Particularly suitablQ for Christmas tree decoratlon are lamps according to the invention ln whlch the llght source ls a night light which is provided with a rlng-shaped cover which moves downwards with the flame.

Another possibility for the decorative uRe of the lamps accordlng to the lnventlon lles in de~igning them as an ad~unct for furnlture, such as example flower vases. ~ere the arrangement can be chosen 80 that between the llght source mounted ln the lamp and the upper end or the neck of the flower vase sufflcient 9paCe i9 left for lnserting cut flowers in the vase.
In thls embodlment the table lamp i9 ~0 to speak a decoratlve core or a decoratlve central feature of a bunch of flowers. The lamp according to the invent~on has, for this purpose, arms which are mounted to plvot and be adjustable on the under~ide of the holder and can be adjusted to fit the nec~ or neck opening of a flower vase and be retained on the vase by mechanlcal lnterengagement or by positive clamping. As sultable materlals for these arms one could consider plastics, porcelain, ceramic and metal, but also other sultable materlals. What is important 19 that the `- 25 security of the holder on the vase should be sufficient for the lamp mounted on the vase not to be able to fall off if the vase is upset or shifted. According to a further embodLment of the invention the grid-shaped cyllndrical sleeve can be provided on it6 interior with 3~ longitudinally extending ribs of metal, plastics or the ! llke whlch serve to retain a candle exactly in the middle of the cylindricaL sleeve so that any wax which may drip does not come lnto contact with the qrid of the sleeve and in fact possibly block the grid. This 3~ embodiment i9 particularly suitable for long candles such as are not unusual for example in churches.

, ,~'':., ~ , ',.' ', '' ' ' ' ' ' ' ' "7,~''' : . ' ., ' ' ' . . , ' . , .

Ecclestastical emblems and so on could be applied to the outside of the grid-shaped wall of the sleeve ao that they do not burn. in this way very simpls plaln and practical candles can be employed, decoratively fitted with the grld-shaped sleeve according to the lnvention.

Also in this case t~e combustion of the candle used as the light source takes place steadily and free from soot. Thls is of by no means negllgible importance in the multitude of candles which are used in a church, not least ~ecause the costs for decoration and posslble restoration are particularly high in ecclesiastical buildings. In addition there i8 the polnt that the brightness of a candle flame 19 still further increased by the grid-qhaped sleeve according to the lnvention because in fact the grld material of the sleeve directs the illumlnating effect of the flame not only upwaras, but also laterally and even downwards, i.e. ln a direction which can be partlcularly appreciated ~y observers who are mostly standing below. The sleeve itself can again be provided with end rings above or below.

~he sleeve of the lamp according to the invention can also be provided with an addition which surrounds the actual lamp or its sleeve in the form of a second sleeve lylng further out and whlch is mounted to rotate with respect to the first sleeve. For example on a central bearing mounted fixedly on the lnner sleeve of the lamp there is ~upported a pin with a ball on its lower end, cn which is mounted a tur~ine dlsk with inclined radial vanes. On its outer periphery there is secured a cylindrical collar which hangs down and encloses the inner sleeve whilst being spaced from it, and for example extends down to the lower edge of the ,~ .
.. . .

lnner ~leeve or indeed lower still. When the candle i9 burning hot air rises from the flame and passes through the turbine dlsk, which is thereby started in rotation around the vertical central axis. In its rotatlon the turbine dlsk takes with it the downwardly hanglng collar or sleeve secured to its lower edge and that accordingly llkewise rotates. Figures or other decoratlve motif~ can be applied to the ~u-face of the collar and rotate with it. Thls embodiment 18 of particular interest for Christmas motifs.

The bearlng in thls embodiment can for example comprlse a cup or an upwardly open bearing dlsh of agate. The co-operating component of this bearlng i9 preferably a small steel ball whlch ls mounted on the lower end of the rotatably mounted pln. One could however also envisage using a needle bearing.

In thls embodlment the candle serving as the light source does not need to be arranged withln an inner sleeve with a grid-shaped surface or outer wall. On the contrary it is sufficient to form the fixed part of the inner sleeve as a transparent frame , for example of wire so that the flame from the candle can shine or illumlnate better through the outer collar.

Various embodiments of the lamp according to the inventlon are illustrated diagrammatically in the drawlng, in which:

The table lamp illustrated in Figures 1 and 2 comprlses a candle 1 wlth a wick 2 arranged centrally ln it, which can burn with an open flame 3. On the substantially cylindrical outslde of the wax body 4 of the candle 1 there are vertically extending wedge-shaped ribs 5 uniformly angular spaced apart as shown in particular in figure 2.

A sleeve 6 which is cyllndrical in plan view is fitted from above onto the candle 1 which, in the embodiment of figures 1 and 2, also forms the base and holder of the lamp. It largely encloses the candle 1, as shown in Figure 1. ~owever, as shown in Pigure 2, the ribs 5 keep the sleeve 6 in a concentric spacing from the candle 1 and in particular from the wick 2 arranged centrally withln it, so that the flame 3 cannot come lnto contact with the inner surface of the , - ' . -- , . , . -,.

sleeve 6 with the lamp ln a more or less normal attltude.

The sleeve 6 comprises a cylindrical outer wall 7 made of an open-mesh or grid-llke flame-resistant and non-flammable fabric material which is knitted, woven, felted crocheted or otherwise formed. An end rln; 8 is secured on each of the two ends of the sleeve 6.

Figure 1 ~hows that the sleeve 6 i9 not fitted fully over the candle 1 but stops short a few mlll~meters above the lower end of the candle 1. In thls way lt ls ensured that any molten wax which may drlp from the candle can escape laterally and aoes not come into contact with the wall 7 of the sleeve 6. For llghtlng the candle 1 the sleeve 6 can first be removed. As the candle 1 burns the hot rising air ln the sleeve 6 comlng ~rom the flame 3 causes a chimney effect so that fresh air ls drawn in simultaneously through the openings in the mesh-like wall 7 of the sleeve 6 and rises together wlth the hot rising products of combustion. In this way the flame 3 18 stabllise~ so that it does not flic~er or wave about in 25' the turbulent alr normally present ln a room. Thls results ln trouble-free combustion, virtually ellminatlng any emission of soot.

In the embodiment of the lamp shown in figures 3 and 4 there is provided a candle 9 which has at its lower end two lateral projections 10 and 11. As shown in figure 4 these projections 10 and 11 are formed as laterally projecting tongues. The tongue-like projections 10 are shorter than the llkewise tongue-shaped projections 11 and serve to centralise ~ the lower end of a sleeve 6 which is fitted onto it 90 'i ' :' ~.

that lts wall 7 of fireproof me~h or grld materlal cannot come lnto contact with the burnlng candle and ln partlcular with the flame 3 itself. Again there ls an end rlng 8 on both the upper and lower ends of the sleeve 6. Between the tongue-shaped projectlons 10 and 11 there are gaps 12, as shown ln figure 4, through whlch any wax which drips or flows downwards can flow away wlthout comlna into contact with the grid-shaped wall 7 of the sleeve 6.
In thls embodlment little stars are applled to the upper part of the sleeve 6 as decoration and can be made of paper, metal or the like. These decorations can be chosen as deslred.
In the embodlment of a lamp accordlng to figures 5 and 6 there is a candle 14 wlth a central wick 15, the candle belng surrounded by a laterally pro~ecting relnforcement 16. The candle 14 with this reinforcement 16 i5 inserted in a base 17 made of metal, plastics, ceramlc or the like. The base 17 ha~
a lower outwardly encircllng bead-llke foot portion 18 I and a neck-shaped cyllndrical collar 19 upstanding from q ' the foot, on whlch a substantially cylindrical sleeve 20 is fitted from above and can thereby be held by it to be concentric with re~pect to the candle 14. The - sleeve 20 comprises a largely cylindrical wall 21 which can be made from mesh-shaped or grid-shaped flame-resistant and incombustibly formed or treated material such as for example, a weave, net, web, fabric or other network of glass sllk or glass wool fibres. ~
, Again there are end rings 22, arranged on the upper and ~ -,~ lower ends of the sleeve 20, giving the sleeve a 3 certain stability.

In the embodlment o~ figure~ 5 and 6 the sleeve 20 or rather its wall 21 is provided near lts upper end wlth a bead-shaped widened portion 23 for decoration.
An annular container 24 18 hung ln the upper end of the 5sleeve 20 and recelves an absorbent insert 25 which can be used to retain perfume or for example a volatile fly killer and Ls made for example of glass wool. The contalner 24, and thereby the a~sorbent lnsert 25 pre~ent within it, 19 heated by the hot alr rislng lQwlthtn the sleeve 20 so that the llquid medium present _ ln the contalner, or rather in its i~sert, i8 continuously volatilised and thereby evaporated.

In this embodiment any dripping candle wax can be 15collected by the base 17. Xere agaln the result is achieved that thls wax cannot come ln~o contact wlth the wall 21 of the sleeve 20 so that lt al~o cannot obstruct the openlngs in lt.

20In the embodlment illustrated ln figures 7 and 8 there ls shown a lamp in which a mass-produced candle 26 wlth a moulded-in wlck 27 finds use. On the floor of a shell-shaped ba6e 28 which ls hexagonal in plan ~ vlew there is secured a pointed spike 29 on whlch the 25candle 26 ls impaled 90 that it 19 held central in the base 28.

Also in this embodlment there is provided a sleeve 30, whlch can be detachably fitted onto the base 28 and 30whlch,. matching the shape of the base, has a hexagonal outline in plan, as shown in particular in Flgure 8.
The base 28 has at its lower end a bead-shaped outwardly projectlng widened portion 31 engaged by the lower end of the sleeve 30 placed on lt as shown in 35figure 7. A collar 32 which is hexagonal in plan view extends practlcally vertically upwards from the widened ,~' ~ " ' . ' ' "

portlon 31 and supports the lower end of the sleeve 30 fltted over lt and thereby ensures that the sleeve 30 when fitted i9 vertical and concentric in relation to the candle 26, so that lts flame 3 cannot come into contact with the sleeve 33. As shown in flgure 7 the base 28 ls of shell-like form and serves to receive any molten wax whlch may drlp from the candle 26.

The sleeve 30 i9 also provided in thia embodlment wlth an end ring 34 at both lts upper and lower ends.
_ Between the two ends of the sleeve 30 there ls - arranged, also on lts outer surface, a further ring 35 intended for decorative purposes and it can sit slidably on the sleeve 30 and carries for example lS decorative pictures and/or decorative openings.
Again, in this embodiment the wall 33 of the sleeve 30 comprlses a mesh-like or grid-shaped flame-resistant and incombustibly treated material containing a number of openings as in the embodlments described earller.
In the embodiment accordlng to flgures 9 and 10 a commercially available night light 36 i9 used. This night light 36 i9 inserted in a shell-shaped base 37 havlng an upstanding rim 38 so that it cannot be displaced sideways. Moreover there ls fltted onto the base 37 a sleeve 39 which i~ circular in plan view and accordingly of overall cylindrical shape, the sleeve in thls embodlment of figures 9 and 10 havlng no lateral support because the sleeve 39 ls secured agalnst lateral displacement by the upstanding wall 40 of the nlght light 35 when it is incerted in the base 37.

lower end of the sleeve 39 as in the embodiments by way of example explained earlier.

In the embodlment of the lamp illustrated in figures 11 and 12 the holder i9 in the form of a contalner 43 and is provlded wlth a lid 4~. Both parts of the holder or ~tand are made of f ~ re-resistant material such ~ glas-~, metal or the like. The lid 44 has a central opening for a wick 45 at the free end of whlch an open flame 3 can burn. The container 43 contains liquid fuel 46 such as petroleum, kerosene or --- the like which i9 sucked up by the wick hanging in the container 43 and fed to the flame 3 burnlng centrally above the lid 44.
The contalner 43 has a central cylindrlcal collar 47 and a radial bead-shaped foot 48 projecting beyond the collar. As shown in figure 11, there i8 fitted onto the collar 47 of the container 44 a flask-shaped sleeve 49 formed liXe the gla~s cylinder of a known petroleum lamp, lts widened lower end 50 belng seated on the cylindrlcal collar 47 of the contalner 43 and ~ -located by it. ~oth at the upper and also the lower ; ~ ;
end of the sleeve 49 there is a respectlve end ring Sl or 52 ~urroundlng it, the ring 51 on the lower end 50 corresponding about to the height of the collar 47, whilst the ring 52 present on the upper end of the sleeve 49 i8 of smaller depth.

In all the embodlments referred to so far and al90 in those explained later the mesh-llke or grid-like materlal forming the wall of the sleeve in que~tion, which can be lit up by the light source present inside ~ ~ -the sleeve, can be decorated in many ways, for example with Christmas motif~, star signs, flowers, pictures of animals, advertislng marks and other emblems. This ,j -- . . . .

results ln a multltude of possibllitles for introduction and use of the lamp according to the lnvention, which can be used both in closed rooms and also, ln an appropriate ver~ion, in the open air.
In the embodiment of figures 13 and 14 the lamp again has a commercially available candle 53, or one of commerclally usual dlmenslons, ~-th a wick 54 arranged centrally ln it, which can likewlse burn with an open flame 3. The candle 53 i9 in~erted ln a base 55 wh~ch serves as a holder and which in the embodiment lllustrated by way of example has four ribs 56, which extend towards the centre of the base and which are arranged dlstrlbuted at uniform spacing around the perlphery of the base 55, which ls circular ln plan vlew. The ribs 56 have angled cut-outs 57 directed towards the centre of the base 55 and cut-off end faces 5~ which lle at such a spacing from one another and are of such dimenslons that candles of different dlameters ~ :
can be lnserted ln the base 55. In the embodlment lllustrated by way of example a candle 53 having an outslde dlameter of 40mm is inserted ln the base 55 wlth lts bottom end restlng on the cut-out~ 57 of the !
rlbs 56. A candle havlng a dlameter of 20mm can also - 25 be lnserted and it fits between the end face~ 5a of the rlbs 56. A night llght havlng a diameter of 40mm likewise flts lnto the lamp of flgures 13 and 14.
Such a nlght llght would, like the candle 53 whlch i6 lllustrated, rest on the angle-shaped cut-outs 57 of the rib`s 56.

The lamp according to figures 13 and 14 is provided wlth a cylindrical sleeve 59 which is fitted onto the base 55 and located with re~pect to the lnserted candle 53 by the outer ends of the ribs 56.
The wall 16 of the sleeve 59 also in thls case : ', ': ' comprises a mesh-llke or grid-shape flame reslstant and non-flammable materlal although the sleeve, as also in the embodiment~ described earlier i8 incombustible. As ln the other embodiments by way of example there are end rings 61 on the outer ends of the sleeve 59, servlng also to stabllise the sleeve.

An airtight collar 62 19 arranged on the sleeve - 59, extending ovsr a large part of the sleeve and extending over the greater part of the height of the sleeve 59 and leaving free only a gap 63 ln the lower part of the 31eeve 5~ through which fresh air can enter. In this way when a candle 53 is alight there - arlses wlthln the sleeve 59 a certain chimney effect because fresh alr can only enter from below through the - gap 63. As the flame 3 is covered apart from this by the collar 62 of ~ilm material and is thereby protected, ln thls embodiment even ln the presence of strong alr flow from outside, for example ln a wind, a steady and thereby soot-free combustion takes place so that the lamp of flgures 13 and 14 is also suitable for use in the open air.

In the embodiment of the lamp according to figures J 25 15 and 16 a candle 63 with a wlck 65 arranged centrally within it 19 arranged in a substantial conical shaped -- sleeve 66. The conicity of the wall 67 of the sleeve 66 is chosen so that the flame 3 from the candle 64 cannot come lnto contact with the wall 67 even when the lamp is not standing exactly upright. As in the embodiments described earlier, the wall 67 is made likewise of a mesh-like or grid-6haped fire-resistant and non-flammable material. As ln the embodiments described earlier there i~ an end ring 68 arranged on the outside of the sleeve at both the upper and lower ends of the sleeve 66.

, ,',, : ~

On t~e outslde of the conical part of the sleeve 66 there 18 an airtlght conlcal collar 69 which covers over the greater part of the wall 67 of the sleeve so that a gap 70 or 71 remalns free only at the lower and upper ends of the sleeve 66, whereby air can flow into the interlor of the sleeve 66 and out of this sleeve through these gaps. Rowever, as in the embodlments described eaLlier, the sleeve 66 i9 upwardly open 80 that the hot air emerging from the flame 3 e~capes largely through this opening.

In this embodiment a two-part base 72 is provided as the holder. The base 72 comprises an outer ~hell 73 serving as a ~oot and thereby a~ a support with a radially outwardly projecting rim 74 and an upstanding cylindrical collar 75 which locates the sleeve 66 placed on it, with respect to the candle 64. ~he lower end of the sleeve rests on the radlally pro~ectlng rlm 74.
Arranged ln the middle of the shell 73 ls an upstandlng hollow bush 76 serving to recelve a mountlng 77 in whlch the candle 64 i9 insertea~ as shown in partlcular in flgure 15. The mounting 77 ls provided wlth a pln 78 which fits in the bush 76 and is inserted ln it.

~ oth flgure 14 and flgure 16 show that sufflcient clearance 79 or 80 remains between the sleeve 59 or 66 and the candle 63 or 64 so that any wax material which may drip over the outer edge of the candle 63 or 64 can flow away downwards and collect in the base 55 or 72 without coming lnto contact with the wall 60 or 67 of the associated ~leeve so that the wall and lts openings can also not become blocXed by dripping candle material such as wax.

3~
Wl~h the candle 64 alight fresh air enters the sleeve 66 from below through the gap 70 and rlses upwards within the sleeve. On account of the upwardly conlcally tapering shape of the sleeve 66 the combustion i9 particularly good. The co7lar 69 en~ures good shielding agalnst the wind. It can however also be removed by taklng lt upwardc or lt can be replaced by another collar.

In all the embodlments descrlbed 80 far the base for the candle and sleeve serves as a holder for the lamp. Attachment elements or even a foot can be mounted on thls holder, as explalned in the following in indlvldual further examples.
In the embodiment lllustrated ln flgure 17 a nlght light 82 wlth a central w~cX 83 in it and a wick holder 44 19 lnserted in a shell-shaped lower portLon 81.
Also in thls embodiment the night light burns with an open flame 3.

In the upper part of the nlght light 82 there is fltted onto it a ring 85 of non-combustlble material ~- such as for example metal, tapering conically downwards and having at lts upper end an outwardly extending circumferential flange 86 bent over at rlght angles.
The rlng 85 and the flange 86 mounted on it are of good thermal conductlvity 90 that as the candle burns down the rlng 85 19 displaced downwards and flnally vanishes into the shell-shaped lower portion 81. ~he horlzontal flange 86 prevents the ring 85 belng able to dlsappear to far lnto the lower portion 81.

In the lower portion 81 below the nlght light 82 there is an upwardly bowed leaf spring 87 on which the lower end of the night llght 82 and the wick holder 84 ,~,,, -, , , ) ~''' ' .
, ~., , present in lt rest. When t~e night light 82 i9 burnt out lt 19 ~ufficient for one to exert pressure, either directly or through the ring 85, on the night light and further stress the leaf spring 87 ln order to release the residual wax and the wick holder from the lower portion.

In the embodiment illustrated ln Fig~lre 17 the lower portion 81 serv$ng as a holder is arranged on a lamp-shaped base ~8.
_. : :
The shell-shaped lower portion 81 has at its upper end an lnwardly off~et circumferentlally extendlng collar 89 on whlch can be fitted a sleeve 90 serving as the lamp body, so that it is seated concentrically with respect to the flame 3. The sleeve 90 again in this embodlment has a cylindrlcal wall 91 maae of flame-resistant and non-co~bustible grid-like or mesh-llke materlal. End rings can be provided on the upper and lower end~ of the cylindrical sleeve.

In the embodiment of flgure 17 the lower end of the candle 82 is ln a shell-shaped bowl or pot 92 ~ having an lnternally conlcal side wall 93, tapering upwards in cross section and they receive the ring 85 between them.

The embodiment of the lamp lllustrated in ilgure 18 ls deslgned for mounting on Christmas trees. On the lower face of a shell-shaped portion 94 serving as a holder there is provided a clip 96 joined through a ball ~oint 9S and serving for fitting onto a branch, not shown, of a tree such as a Christmas tree. A
! rigid spike 97 is provlded withln the clip 9~ and can 35 peDetrate thro~lgh the branch on whLch the clip 96 is : ' fltted, ln order thereby to prevent lateral tilting of the clip 96 and thereby of the whole lamp.

The lower portion 94 has an upstandlng cylindrical slae wall 98 of which the upper end 19 formed as an lnwardly offset collar 99. A sleeve 100 can be detachably fltted onto this collar 99, as shown in flgure lh. The sleeve 100 has an end ring 101 at each of its ends and has a cylindrical wall 102 which comprises a grid-shaped or mesh-like flame-reslstant and non-combustibly treated material as in the embodiments descrlbed earlier.
::
A nlght llght 103, which can burn with an open flame 3, 15 inserted in the lower portion 94 as the light source.

A cover 105 having air holes 104 is fltted onto -~
the upper end of the sleeve 100 and serves as a cover and as a holder for an upstanding disk provided as decoration. This dlsk can bear a plcture of a flame or a star.

In the embodlment according to figure 19 a clamp-shaped ad~ustable foot 108 18 arransed on the shell-shaped lower portion 107 of the lamp and serves for mountlng the lamp on the neck 109 of a vase 110.
The foot 108 comprlses three hanging arms 111 mounted to plvot lndivldually about horizontal axes, capable of being swung inwards or outwards by means of a rotatable ad~usting spindle 112 in order to be able to grasp mechanically according to need, the outer end 114 of the neck 109 of the vase 110 by means of notches 113 provlded on thelr free ends. It wlll be seen that sufficient space is left clear between the upper end 114 of the neck 109 of the vase 110 and tne lower ~',' , ",,; ~ ' portlon 107 of the lamp serving as the holder, in order -to be able to put flowers in the vase 80 that the lamp can serve, 80 to speak as the centre polnt or core of a flower arrangement.
