Abstract

The day of the month is shown by characters (9,10) on adjacent display wheels (4,5) which are marked with units and repeated tens. The wheels are turned by pinions (6,7) which engage with toothed wheels (31,32) which have twenty nine and five differently spaced teeth respectively. The toothed wheels are rotated by a third coaxial toothed wheel (30) and a drive pinion (21) An Independent claim is also included for : A timepiece which includes the mechanism
