Abstract
Abstract TO PREVENT DAMAGE BY ROTATING MECHANISMS WHICH INTERMITTENTLY START AND STOP MANY TIMES PER MINUTE, AS FOR EXAMPLE IN A PITNEY-BOWES STAMP METER MACHINE, THERE IS PROVIDED BRAKING MECHANISM WHICH IS SELF-ACTUATING AND EFFECTIVE ONLY IN THE RELATIVELY SHORT INTERVAL OF TIME BEFORE THE STOPPAGE OF ROTATION OCCURS DURING EACH CYCLE OF OPERATIONS. THE BRAKING MECHANISM IS IN THE FORM OF A SPECIAL GEAR WHICH FRICTIONALLY ENGAGES A STATIONARY ELEMENT TO CAUSE A DRAG ON THE ROTATING MECHANISM DURING THE FINAL 25% OF TRAVEL OF THE ROTATING MECHANISM IMMEDIATELY BEFORE THE ROTATING MECHANISM ARRIVES AT THE HOME OR REST POSITION IN EACH CYCLE OF OPERATION.
