<p>Disclosed is a file assembly which is adapted to be fitted in and integrally connected to the top of a gas lighter housing, comprising a rotatable file disk and a file block having two opposite support plates each having a semicircular-and-wide-and-narrow slot made on its inside, leaving its outside for ornamental space. Necessary bearings for the flint wheel can be formed by inserting narrow-and-wide rectangular pieces in the semicircular-and-narrow-and-wide slots of the opposite support plates, leaving the semicircular-and-narrow rectangular spaces enough to snugly accomodate the opposite ends of the axle of the flint wheel, thereby eliminating the necessity of making very small pivot holes exactly at selected places in selected parts of the lighter, and hence reducing the manufacturing cost by as much as would cost if such very small holes were made exactly at selected places in selected parts of the lighter.</p> |
