<p>#CMT# #/CMT# The mechanism (1) has display mechanisms (3,4) that provides drive mechanisms (30,40) driven by movement (2) and correction mechanisms (300,400) driven by adjusting element (50). A disc drives display mechanism and carries radial drive finger. A cam having steep ramps operates drive disc for display mechanism. The disc drives display mechanism experiencing slow movements of pin (73) moving in oblong groove and pivoting with a stack, coaxial to drive wheel (71) on the arbour. The travel of pin in oblong aperture defines a good period when the disc is not driven. #CMT#USE : #/CMT# Mechanism for displaying and correcting state of two different time measurable quantities for timepiece with calendar mechanisms such as date display, moon phase display, tide display and day or night display connected to time display,or scientific apparatus. #CMT#ADVANTAGE : #/CMT# The state of two different time measurable quantities for timepiece or scientific apparatus can be displayed and corrected effectively. A reliable, simple and economical solution can be provided to the safety of display mechanisms when the correction mechanisms are operated. The friction safety device can be provided for preventing any correction that is performed when an instantaneous display jump is prepared or carried out. The user can perform corrections on mechanisms for displaying different measurable quantities. The requirement components and spacefor mechanism can be reduced. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a front view of the timepiece mechanism including dragging moon phase mechanism and instantaneous date display mechanism. 1 : Timepiece mechanism 2 : Movement 3,4 : Display mechanisms 30,40 : Drive mechanisms 50 : Adjusting element 71 : Drive wheel 73 : Pin 300,400 : Correction mechanisms.</p> |
