ABSTRACT:
A marking device with a reciprocating needle. The needle is attached to an armature which reciprocates in a slot in a housing by a crank which is rotated by a motor in the housing. Vibration of the motor and tolerances between the armature and track cause unwanted movements of the needle in a plane perpendicular to the reciprocating motion. Guide bars and bushings connect the armature to the track. Tolerances between the guide bars and bushings are less than tolerances between the armature and track. An armature bracket is detachably connected to the housing in order to partially or fully close off an open end of the track after the armature has been inserted into the track. Guide bars and bushings then connect the armature and the armature bracket. The motor is supported on only one end by bolts extending from a mounting wall inside the housing. A damping plate is positioned between the motor and the mounting wall, and a damping ring is positioned between, and contacts, the damping ring and the housing. The damping ring is made of material to absorb or block vibrations. Undesirable movements due to a vibration of the motor and tolerances between the armature and the housing are thus removed.
