Abstract
An adjustment device for liquefied gas lighters is disclosed, which allows precise automated setting of maximum and minimum permitted flame heights during the assembly of lighters which have a rotatable valve adjustment member extending from a valve well in the lighter. Fixed stop means are provided on the lighter. An adjustment mechanism rotates with the valve adjustment member and after adjustment of the flame height, movable stop means are formed in the adjustment mechanism in positions chosen such that the movable stop means can abut the fixed stop means at positions of the adjustment mechanism corresponding to maximum and minimum flame height, respectively.
