  • Inking mechanism for postage meters and price stamping machines
    Patent number: 4969394
    Abstract: An inking mechanism for postage meters and price stamping machines includes an ink transport roller, an intermediate roller and an inking roller being operatively connected to one another and having surfaces. The surface of the intermediate roller transfers ink from the ink transport roller to the inking roller and the surface of the inking roller is formed of porous material. An ink supply container in the form of a tank has a slit-like opening formed therein. Porous material substantially fills the tank as a storage medium for stamp ink. The porous material protrudes out of the slit-like opening in the tank and contacts the surface of the ink transport roller in the form of a squeegee.
