  • Patent number: 4806039
    Abstract: A chalk liner has a vessel shaped main body having a chalk chamber to be charged with chalk powder, an opening formed in the lower end of the main body for dropping the chalk powder from the chalk chamber, a gear disposed in the opening for drawing lines on a cloth by the dropped chalk powder, and a cartridge for supplying chalk powder into the main body, which is fittable in the chalk chamber of the main body and detachable therefrom. By installing the cartridge in the main body, the chalk powder previously charged in the cartridge is supplied into the chalk chamber of the main body. When the chalk powder within the main body runs short during the lining operation, the cartridge is detached from the main body and another cartridge which is previously charged with chalk powder is installed in the main body. This enables the easy recharge of chalk powder in a short time.
