Device for locking the printwheels of a postage meter

摘要

A device for positively locking the printwheels (2) fitted to the print drum (1) of a postage meter. A tilting bail (5) locks the printwheels (2) against the force of a return spring (8). A sliding pull rod (26) provided with a yoke (30) that co-operates with a fixed collar (31) disposed coaxially with the rotary drum (1) ensures that locking is secure by preventing an arm (11) of the bail (5) from moving whenever the drum (1) is rotating.
