Abstract: A self-inking stamping device of the type which inverts as it travels between inking and printing positions upon movement of an actuating member. A stamping insert is pivoted on the actuating member and comprises a frame which is provided with a fixed printing plate and a stamping belt unit movably mounted in the frame of the stamping insert and comprising a plurality of juxtaposed parallel endless stamping belts, which are longitudinally adjustable relative to each other and carry type protruding through an aperture of the printing plate. The stamping belt unit is adjustable by a screw mechanism in a direction which is normal to the plane of the printing plate.

Abstract: An integral plastic housing has front and rear walls, which terminate in downwardly extending tongues which define slots open at their lower ends, and two opposite side walls adapted to be resiliently spread apart and formed with axially aligned apertures. An axle is snap-fitted in the apertures. A cross-piece is fitted on the side walls at the lower end of the housing. At least one drum is mounted on the axle and rotatable about the axis thereof and integrally formed with a setting wheels which protrudes through the slots. At least one stamp band is trained around the drum and the cross-piece and adapted to be engaged with the underside of the cross-piece and to be forced by the latter against a surface to be stamped. The side walls are adapted to be sufficiently spread apart to permit the axle to be inserted into the housing from below and to be snap-fitted into said apertures.
