Abstract

The friction coupled device for a clock movement has an axially aligned tube and shaft. The tube presents an angularly located markings sepd. by an angle between 1 and 179 degs. In the coupled position, the tube contacts with the shaft axis following a common generator and both points. The axis comprises a circular groove, with the tube markings coming into contact with the bottom of the groove in the coupled position.
