Mechanism for displaying and correcting the state of two different time measurable quantities

A timepiece mechanism for displaying and correcting a state of two different time measurable quantities for a timepiece or a scientific apparatus comprising:

• a timepiece movement, including or driving at least a first display mechanism to display a first measurable time quantity and a second display mechanism to display a second measurable time quantity, said movement including an adjusting member, and wherein said first display mechanism and said second display mechanism respectively include a first drive mechanism and a second drive mechanism, which share a common drive mechanism, which is driven by said movement, and which controls a driving of one of said first display mechanism and said second display mechanism by instantaneous jumps under an action of a jumper spring, and which controls a driving of the other of said first display mechanism and said second display mechanism in a dragging manner, and wherein said first display mechanism and said second display mechanism respectively include a first correction mechanism and a second correction mechanism, which share a common correction mechanism, which is driven by said adjusting member, which is independent of said common drive mechanism, and which includes at least one friction safety device preventing any correction being performed when an instantaneous display jump is being prepared or carried out, wherein said common drive mechanism includes, pivoting integrally with each other relative to an oblong groove of a drive wheel directly or indirectly driven by said movement, a cam on which a release spring permanently exerts stress via a release lever, a disc driving said first display mechanism and carrying at least one radial drive finger, and a disc driving said second display mechanism and carrying a radial drive finger, said cam comprising steep ramps to instantaneously operate said drive disc for said second display mechanism, whereas said disc driving said first display mechanism only experiences slow movements of a pin moving in said oblong groove and pivoting integrally with a stack, coaxial to said drive wheel on an arbour, including said cam, said drive disc of said first display mechanism and said drive disc of said second mechanism, a travel of said pin in said oblong aperture defining a period during which said disc is not driven.
