Definitions

  • our invention relates to pyrophoric lighters.
  • the usual pyrophoric lighter comprises a serrated wheel which is engaged by a spring-pressed pyrophoric element. Each time that the lighter is operated, a step of rotative movement is imparted to the serrated wheel.
  • the serrated wheel of such a pyrophoric lighter is loosely mounted on a member or axle which, in an improved manner, is nonrotatably secured to a pair of supporting standards therefor.
  • Our invention has further reference to ratchet mechanism for imparting step-by-step rotative movement to the serrated wheel of a pyrophoric lighter, such mechanism comprising a clutch disk which is supported in a novel manner by a tubular extension or shoulder which projects from the serrated wheel.
  • our invention relates to novel pinion or gear segment arrangements which are associated with the side walls of a snuifer lever to thereby prod-uce an oscillatory unit forming part of the lighter mechanism.
  • our invention relates to a method of producin a serrated wheel for a pyrophoric lighter which involves the initial formation of chamfers or bevels at the peripheral corners of an unfinished wheel and the subsequent formation thereon of peripheral serrations and side face ratchet teeth.

  • a lighter mechanism of the character described above is advantageous in several respects.
  • the member or axle 3 by virtue of the described clamping arrangement therefor, continuously remains stationary or non-rotatable with respect to its supporting standards 2. Therefore, during operation of the lighter mechanism, there is no tendency for wear to occur between the member 3 and said standards 2 with resultant enlargement of the standard passages 2a and consequent undesired misalignment of the lighter parts.
