Definitions

• the subject invention concerns a device for extinguishing the flame of a candle to prevent that the flame of the burning candle progresses so far along the length of the candle that there is a risk that the flame will cause fires.
• the invention is characterized by a sleeve of heat-shrinkable plastics which is applied about the candle so as to encircle the latter, which sleeve, when affected by the heat generated by the candle flame, is arranged to shrink and thus at least partly close about the end of the candle, thus extinguishing the flame.
• the candlestick 1 illustrated in the drawing comprises a number of candle holding members, two 2 and 3 of which are shown in the fragmentary view, of the drawing.
• the candlestick is filled with e.g. dried moss 4 or other flammable materials.
• Candle holding member 2 supports a burning candle 5. At the lower part of the candle 5, a considerable distance below the burning flame 6 and immediately above the moss 4, a sleeve 7 of heat-shrinkable plastics is applied around the candle.
• the plastics could be translucent so that it will be practically invisible, if desired, and contrary to the situation illustrated in the drawing figure.
• the candle holding member 3 supports an extinguished candle 8.
• This candle has burnt to the point where the heat from the burning flame has heated a plastic sleeve 7' corresponding to sleeve 7 on candle 5.
• the upper part of the sleeve 7' therefore has started to shrink and contract about the upper end of the candle 8.
• the supply of oxygen to the flame therefore is reduced and the flame size is diminishing.
• the gasification of the material (stearine) of the candle 8 is reduced, leading to extinction of the flame.
• the plastic sleeve 7, 7' may be displaced along the candle 5, 8 and it may be stopped at any desired level above the candle holding members 2, 3 according to wish. For instance, it may sometimes be desired to fill the entire candlestick with moss 4 which thus will reach up to a considerable level along the length of the candle 5, 8. Consequently, it becomes necessary to ensure that the candle is extinguished comparatively early, well before the flame approaches the moss. At other times, for instance when a candlestick holding four candles is used, one for each Sunday of Arts, one may wish to extinguish the candle lit on the first Sunday of Arts after just a brief period of burning to ensure that the candle could be lit also on the following three Sundays of Arts.
• the desired burning time is easily established in advance by placing the device in accordance with the invention at the desired level along the candle, whereby extinction of the candle flame will be achieved automatically at the desired point.
• extinction of the candle flame will be achieved automatically at the desired point.
• a candle 5, 8 which has been extinguished by the pl stic sleeve 7, 7' after the preselected burning time can easily be relit by removing the plastic sleeve and replacing it by a fresh sleeve which is positioned at a lower level around the candle. If the plastic sleeve 7, V is sufficiently long it may quite simply be cut off to remove the heat-shrunk part thereof and the remainder of the sleeve be appl ied further down along the candle 5, 8 for re-use.
