An article marking apparatus of the reciprocable impact type wherein an imprinting head is driven from a rest condition in sealed engagement with an inking cartridge through a ninety degree rotation to impact upon the surface of a passing article whereby to imprint indicia information thereon by means of printing type carried by said imprinting head. The imprinting head is pivotally coupled to a pneumatic drive device by a linkage. A guide is provided to define the path taken by the head. In one embodiment, the coupling includes a folding linkage and the guide includes a resilient bumper intercepted by a portion of the head in its travel along the path. A modified embodiment provides a guide in the form of a cam slot and follower arrangement. A cushioning member is provided to receive the impact of the imprinting head against the ink cartridge. A dished sealing plate also can be provided, along with a resilient gasket adhered to the imprinting head, whereby to achieve a seal between cartridge and imprinting head during the rest condition and to control the impact of the imprinting head upon the article during imprinting. |
