Abstract (en)
[origin: EP1586962A2] The mechanism has levers to drive a date mobile. The mobile is moved instantaneously by a small ratchet (14) when a day passes to next day within a month and when last day of a month of 31 days passes to the first day of following month. The mobile is moved partially in a dragging manner by a large ratchet (40) when the last day of a month less than 31 days passes to the first day of the following month. The date mobile is constituted of a date star (16), a date wheel (28) with 31 teeth, a unit wheel (29), and a tens wheel (30) with four teeth and a correction cam. The respective levers carry the small ratchet (14) and the large ratchet (40). An independent claim is also included for a clock piece.
