The mechanism has movements (24) provided with abutments (44) and arranged to act alternately on a control unit (30) to move a locking lever (10) between positions. The lever is moved to one of the positions when a reassembly train i.e. ratchet (18), is actuated, and a barrel arbor (4) is traveled through a pre-defined angle and moved the other position when a drum (2) is traversed through an angle approximately equal to that of the pre-defined angle so as to lock the drum and allow later reassembly of a spring (40) of a barrel (1). |
