This section the casing is located to fl11flpf the center plane 65 istaken on line Ill-4i of Fig. 11. A--A in order to accommodate the ignition 65' mechanism. It is, however, imperative that the entrance hole 28 be located to the right of the center plane A-A for a reason that appears obvious later; therefore, the tubular member 25 is slightly bent as shown in Figs. 2 and 3. The exposed end of the wick is also located to the left of center plane B -B (see Fig. l) to accommodate the ignition mechanism. It is, however, imperative that the entrance hole 28 be located to the right of center plane B--B for a reason that ap' pears obvious later, therefore, the tubular mem her is also curved as shown in Fig. 1. ticularly, entrance hole 28 is. so located that the fuel supply in. the casing can under no circumstances flood the entire wick, the capillary attractionof wick 21 being solely relied; upon in any position of the casing to convey fuelifrom-thesupply to the exposed wick portion. As long as the entrance hole 28 dips'into the fuel supply a substantial portion of the wick is always above the fuel level. The maximum amount of fuel supply in the casing is naturally of great importance for the proper location of entrance hole 28. Regardless of any shape the casing may assume, the following course will always lead to the proper location of said entrance hole. The location of that portion of the tubular member'25 which extends beyond the casing is generally known and it is also known what minimum portion of the wick has to extend above the fuel level regardless of any position the casing may assume. The casing is inverted into a most unfarrorable position in which said predetermined minimum portion of the tubular member 25" extends above an assumed maximum fuel level and the entrance hole 28 will have to be located substantially in said fuel level. Upon inversion of the casing from said most unfavorable position, the portion of the tubular member above the fuel level may immerse into the fuel supply but concurrently therewith the entrance hole 28 moves away from the fuel supply and cuts oil communication between the latter :and the wick, or the portion of the tubular member above the fuel'level will increase and concurrently therewith the entrance hole will dip deeper into the fuel supply. In the present form of the casing, there are two most unfavorable positions that have to be'taken into account, these two positions being illustrated in Figs. 2 and 5, respectively. In Fig. 2 the casing must be assumed to be in a position in which the fuel assumes the dot-and-dash position. It will be noted that as long asthe entrance hole 28 is located substantially in the maximum fuel levels shown there, the wick will never be flooded entirely, it takes at least the capillary attraction of that portion of the wick extending above these illustrated fuel levels 'in order to convey fuel to the exposed wickportion. Supposing the casing 28 assumes the position shown in Fig. a then capillary attraction of the wick hasto convey fuel from the fuel level to the highest portion of the wick above the fuel level. Having determined'the exact location of the entrance hole in the tubular member 25 and havingalso determined the maximum fuel supply in the casing 28, the funnel is extended to the maximum fuel level when the casing is in the position shown in Fig. 4 so that said funnel serves also as an indicator for proper refueling of the lighter, the same being properly-refueled when the fuel level reaches the entrance of the funnel 38. Further pouring of fuel into the funnel 38 would not result in an appreciable rise of the fuel levelbecause the air in the casing above said level is trapped and the funnel would merely overflow. The fun- More parnel;therefore renders a completefilling of the casing impossible and even prevents a filling of the casing beyond a predetermined maximum fuel amount therein. Since the position of the lighter shown in Fig. 1 is that position in which the lighter is used, the entrance hole is naturally located close to thebottom 2| of the casing in I order to make sa isfactory use.even of a slight fuel supply. The long tubular member effectively prevents an explosion of the lighter, a striking back of the flame throughout the entire length of said tubularmember is impossible:

clusivejcomprisesa tubular member 68 to which is braced another member 5i 'containinga wick 62 arranged in the-convolute fashion disclosed in 6*and 8.. One-end of said wick extends through tubular member 88 and the other end thereof is firmly held by a tongue 63jof member 6| which is bent over said other wick end. Whenever necessary, the user will pull out the wick slightly at the free end of tubular member 88 and before the wick convolutions in member 88 are rolled open by such pulling out of the wick end, a

longperiod of time during which the lighter is used will elapse. However, the end held by tongue 63 will not give way under the pull of the user,

therefore the wick 62 always extends through the entire length of tubular member 88 and the latter is long enough effectively to prevent a striking back of the flame into fuel supply. Member 6 l is provided with an opening 64 which is cut out in order to form the already explained tongue 63.

Opening 64 is located at a point inside the case where the maximum fuel supply will never flood the entire wick regardless of any position the casing may assume. Naturally the same course as earlier described will be takenin order properly to locate opening 64.

The modification disclosed in ms. 10 andll comprises a tubular member 18 which is braced or otherwise attached to the top H and also to an internal lug 12 of the bottom 13 of a casing 14. This tubular member contains a wick 15. A plug 16 and gasket 11 seal the internal lug 12. An opening 18 in the tubular member 18 which provides the sole communication between the wick and the'fuel supply I9 is located within the casing 14 in the manner explained earlier so that the maximum fuel supply cannot flood the wick in any position of the housing. Thewick, after having been used up to a certain extent may readily be replaced by removing plug 16 and inserting a new wick into the tubular member 18.
