Abstract
An article marking apparatus of the reciprocable impact type wherein an imprinting head is driven from a rest condition sealably engaged with an inking cartridge assembly through a 90.degree. rotation to impact upon the surface of a passing article whereby to imprint indicia information thereon represented by printing type font carried by said imprinting head. The imprinting head is pivotally coupled to a pneumatic drive device by a linkage assembly including a drive link. The imprinting head mounts a shaft having freely rotatable bushings at its opposite ends. Opposite cam slots are provided formed in the housing for receipt of the bushings for guilding the imprinting head along a predetermined path for translating said head through an imprinting stroke and return while the head is rotated at constant angular rotational accelleration. The peak of the rate of angular rotation of the head occurs midway in the stroke with the head assuming a motion to the terminus. When the terminus of the stroke is reached, the type holder continues inertially to extend from the head to impact gently upon the surface to be imprinted. The return stroke is initiated after impact. The drive link is mounted directly to the plunger of the pneumatic drive; the plunger is mounted on an eccentric pivot axis. The said eccentric axis can be changed to provide a vernier adjustment of the stroke limits.
