  • Spring means 21 on shaft 23 has two end portions, one of which is rested on a bottom end of 9f of the block body 9 and the other of which engages stepped portion 20b of flint pusher 20 so that flint pusher 20 exerts a continuous pressure on flint stone 16 in accordance with wearing of the latter.
  • Support member 25 has concave portion 25a which is adapted to mate with bottom end 9f of block body 9 and further boss 26 adapted to engage bore 27 of bottom end 9f of block body 9.
  • support member 25 is provided with opening 28 which receives rotatably lower shaft 13b of rotor 13 to support the same.
  • member 25 should be of low frictional resistance in order to yield a smooth rotation of rotor 13.
  • synthetic resin may be used for support member 25.
  • flint pusher 20 When replacement of flint stone 16 is required, flint pusher 20 is taken back around pins 19 against the action of the spring means 21 by applying a backward pressure at the top of flint pusher 20 extending upwardly beyond the block body 9, and then rested, as shown by dotted lines in FIG. 2, on lateral end portion 9e of inward extension 9e.
  • a coiled spring is used in this embodiment as spring means 21 arranged on the shaft 23. This coiled spring applies forces to flint pusher 20 in two directions, one toward knurled wheel 12 and the other in the direction of the horizontal axis of shaft 23.
  • flint pusher 20 is maintained on lateral end portion 92 by the action of coiled spring 21 to leave openended window 15a of the flint housing passage open even after the pressure applied on the top of flint pusher 20 is released.
  • Flint stone 16 is then put into flint housing passage 15 from the upper open end thereof.
  • a continuous force is again exerted by the action of coiled spring 21 on flint stone 16 in the direction toward knurled wheel 12.
  • the required replacement of flint stone 16 may be carried out easily and in a short period of time. At the same time. a stable and continuous pressure upon the flint stone is assured by swivel flint pusher 20.
  • cap 1 is pivotably mounted on lighter casing by means of hinge means 3. (Note that FIG. 4 substantially corresponds to the cross-section taken at line IV-IV' of FIG. 2).
  • FIG. 4 substantially corresponds to the cross-section taken at line IV-IV' of FIG. 2).
  • Shaft 105 engages valve opening means 7 which has bent portion 7a thereon in order to be out of contact with lighter casing during the movements of valve opening means 7.
  • Fuel tank 4 is disposed within lighter casing 2 to retain gas which is issued from burner nozzle 108 of a burner valve (not shown) communicating therewith.
  • Fuel tank 4 as base plate 5 which is fixedly attached on top wall 4a and which is formed with female screw 111.
  • screw means 6 including head portion 6a, shank portion 6b and a threaded portion 60 adapted to be screwed into female screw 111 of base plate 5.
  • the diameter of shank portion 6b is larger than that of threaded portion 6 c but smaller than that of head portion 60.
  • screw means 6 holds valve opening means 7 via collar means 8 and coiled spring 117 interposed between collar means 8 and head portion 6a of screw means 6.
  • Collar means 8 (preferably of a synthetic resin) has a through-bore (8a) for slidably engaging screw means 6, and pins 8b and 8c which rotatably receive a pair of slots 7d and 7e made on wings 7b and 7c of valve opening means 7 in order to maintain valve opening means 7 under the influence of the coiled spring 117.
  • valve opening means 7 is movably held in lighter casing and sways in the wake of the movement of cap 1 when the latter is rotated toward the open and closed positions around hinge means 3 secured on lighter casing 2.
  • the pair of cup-like members 1 18 have respectively cutout portion 118a through which cup-like members 118 are detachably mounted on the burner nozzle 108.
  • member 119 Provided under upper cup-like member 118 is member 119 comprising circular portion 119a laid below upper cup-like member 118, aperture ll9b through which the cup-like member 118 is disposed on burner nozzle 108 and T-shaped portion 119C adapted to engage cutout portion 118a of upper cup-like member 118 so as to prevent cup-like member 118 from rotating.
  • Cup-like members 118 and the member 119 are held between peripheral grooves 108a and l08b formed on the burner nozzle 108 through coiled spring 120 interposed between member 119 and lower cup-like member 118.
  • Member 119 is maintained between peripheral grooves 108a and 108b by means of upper and lower cup-like members 118 held respectively within peripheral grooves 108a and 108b on burner nozzle 108.
  • Upper cup-like member 118 disposed within upper groove 108a is held by member 1 19 whose circular portion 119a is in engagement with upper cup-like member 118 to prevent the same from disengaging from burner nozzle 108.
  • lower cup-like member 118 is held on the burner nozzle by coiled spring 120 interposed between member 119 and lower cup-like member 118.
  • Members 118, 119 and 120 cooperatively act to effect, without failure, a smooth controlled engagement between valve opening means 7 and burner nozzle 108 reciprocably arranged on the burner valve (not shown). Moreover, they protect the construction of the burner valve (not shown) which is susceptible to damage by a sudden movement or shock from the outside of lighter casing 2.
  • valve opening means 7 In operation, upon turning cap 1 around hinge means 3 toward the open position thereof, valve opening means 7, is swayed in the right direction around pins 8b and 8c of collar menas 8 and upwardly lifted with collar means 8 along screw means 6.
  • coiled spring 117 acts to apply a downward force upon valve opening means 7 so that cap 1 is rotated automatically toward and maintained open under the influence of coiled spring 117, after shaft 105 of the cap 1 passes a predetermined deadpoint on the extension of a line connecting pin 8b of collar means 8 and axle 3a of the hinge means 3.
  • valve opening means 7 disengage from upper cup-like member 118 arranged on burner nozzle 108, so that burner nozzle 108 may be brought into the operative condition thereof.
  • One means of achieving this result is to arrange burner nozzle 108 to be spring biased and inoperative in the depressed position. In this coiled spring 120 would preferably exhibit a greater resiliancy than the spring of burner nozzle 108. The operation of burner nozzle 108 may be further effected even though a substantial depression of upper member 118 produces only a minor variation in the position of burner nozzle 108.
  • the way of controlling gas emission from the burner valve necessarily depends upon the structure of the burner valve which is actuated by valve.
  • valve opening means 7 through the intermediary of the burner nozzle 108 mounted on the burner valve. Accordingly, the connection between valve opening means 7, and cup-like members 118 may be modified without departure from this idea. For example, if the opening operation of the burner valve required the lifting of the nozzle 108, arms 7f and 7 of valve opening means 7could be positioned beneath lower member 118.
  • valve opening means 7 When cap 1 is returned back to the original inoperative position by the users hand, valve opening means 7, is also moved back to the initial position under the action of coiled spring 117. Then, cap 1 is automatically returned back by the coiled spring 117 after the shaft 105 engaging the valve opening means 7 passes the aforementioned predetermined deadpoint. At the appropriate point of the return movement of valve opening means 7, arms 7f and 7g of valve opening means 7 come into contact with upper cup-like member 118 on burner nozzle 108 in order to depress the same downwardly so that gas emission from burner nozzle 108 may be smoothly ceased. As described above, coiled spring 120 acts to smoothly and resiliently transfer the action of arms 7f and 7g to burner nozzle 108. Therefore, the control of the burner valve may be effected in a stable condition without detriment to the parts of the lighter structure while the cap is turned smoothly toward both open and closed positions thereof.
