Abstract: There is shown an inking apparatus for stamping on a localized area, and with a speedy application, a selected reproduction to a travelling or advanced product. This inking roller is free-turning with a light brake to prevent free wheeling. A four-bar linkage is used with two eccentrics. One eccentric is preferably rotated with at least twice the revolutions of the other eccentric. The four-bar linkage carries on an extending end of a first bar the stamp which is moved into peripheral engagement of the inking roller and then to the surface of the product. The movement of the stamp is in a path prescribed by the eccentrics and the four-bar linkage. The stamp in its peripheral engagement with the inking roller causes said roller to be inched forward rotationally to present a fresh surface to the stamp when next brought to the inking roller.
