Abstract

Abstract A day-indicating disc bears inscriptions of the names of the days of the week in a plurality of languages. Said inscriptions have a uniform angular spacing. The inscriptions of the names of each day in all said languages are disposed adjacent to each other in a regular succession. The inscriptions of the names of the days of the week are arranged in a chronological succession in a given sense. A day-shifting wheel is coupled to said disc and has an annular series of teeth which have the same angular spacing as said inscriptions. A rotatably mounted day-shifting finger is provided, which has an inclined back. Timing means are provided, which serve to rotate said finger in a forward sense through one revolution in 24 hours. Setting means are provided, which are manually operable to rotate said finger in a reverse sense. Said finger is arranged to engage said teeth with the side of said finger opposite to said back to a relatively large depth and to rotate said wheel in said given sense through a predetermined plurality of said angular spacings during each revolution of said finger in said forward sense. Said predetermined plurality is equal to said plurality of languages. Said finger is also arranged to engage said teeth with the back of said finger to a relatively small depth and to rotate said wheel opposite to said given sense through said angular spacing during each revolution of said finger in said reverse sense.
