Definitions

  • the boss is formed integrally with one holdfast and the other end is ball shaped and inserted into an opening in the other holdfa'st after the knurled wheel is placed on the boss.
  • the holdfasts can each be provided with a facing boss, each located in an opposite end of the bore, or the wheel may have a central boss projecting from each side and located in openings in the holdfasts.
  • This invention relates to improvements in flint lighters with a rotary knurled wheel.
  • the knurled wheel is generally mounted on a pin which is either free or integral with the knurled wheel or lighter.
  • An object of the present invention is to simplify and remove these operations, while facilitating the mounting of the knurled wheel on lighters of the so-called disposable type, the flint spring and flint of which are disposed in a recessed pipev before the knurled wheel is positioned.
  • a flint lighter with a rotary knurled wheel comprises said knurled wheel being supported by at least one boss.
  • the free end of the boss is itself secured to the body of the lighter.
  • the knurled wheel is supported by two axial bosses disposed on the body of the lighter and resiliently interconnected in a direct or indirect manner.
  • FIG. 1 is an end view partly in section of one embodiment of lighter formed according to the invention
  • FIG. 2 is a view on lI-II in FIG. 1
  • FIGS. 3 and 4 are fragmentary side elevations partly in section of two further embodiments of the invention.
  • the body 1 comprises at its upper part, two or engagement portions 11 and 12 each of which is provided with a groove 13 and 14.
  • the mounting is carried out as follows: when a knurled wheel 15 has been disposed on the boss 6 of the holdfast 4, the small ball 7 at the free end of this boss is inserted in the perforation 8 of the holdfast 5 to join the boss thereto, and the head 2 is placed on the body 1 so that the catches 9 and 10 of the Taking into account the dimensions of a pocket lighter, this locking is sufficient to hold the head on the body. However, it is evident that if it is desired to make a lighter of greater dimensions, another locking on the same principle must be provided.
  • FIG. 3 instead of arranging the knurled wheel 15 on a single elongated boss, two axial bosses 16 and 17 are provided, disposed in opposition on two holdfasts 18 and 19 moulded with the body 1.
  • FIG. 4 it is the knurled wheel 20 which supports two bosses 21 and 22 which are journalled in two housings 23 and 24 of two holdfasts 25 and 26.
  • FIGS. 3 and 4 could be combined by using a knurled wheel with a boss on one side and a housing on the other side, the boss, in the housing, taking the place of the head of the lighter, and the housing provided in the knurled wheel receiving a boss moulded with the head of the lighter.
  • One advantage of the arrangement is that the asymmetry of'the knurled wheel makes it possible to position it with an automatic sorter even when its ribs are orientated.
  • a flint lighter comprising:
  • said head including opposed flanges and being sufflciently elastic to enable the flanges to be separated to allow the wheel to be inserted between said boss means coupling said'wheel and said flanges to enable the wheel to rotate,
  • a lighter as claimed in claim 1 wherein said groove and catch means comprises catch members on said flanges so positioned to lockably engage said engagement portions to hold the sub-assembly on the body in substantially rigid engagement.
  • a lighter as claimed in claim 1 wherein said boss means comprises a boss on each flange rotatably re ceived in a bore provided in said wheel.
