Abstract: An imprinting device for selectively marking a surface, for example a container, web, or the like, comprising a frame member having a power cylinder mounted thereon with a power arm ram reciprocatable in a first direction. A rigid non-sliding linkage connects the ram to a pivotable yoke member carried by the frame which in turn is pivotably connected to a type carrying member carrying a stamp head. The tupe carrying member is pivotable around a fixed point on the frame through a lost motion connection. The stamp has a vertical stamping movement and a horizontal inking movement. In the vertical movement the stamp projects above a plane of the frame while in the horizontal movement it is brought into contact with a disposable ink cartridge carried by the frame.
