Day-date mechanism for travel clock

摘要

A day-date mechanism which includes an annular "day" ring and an annular "date" ring having adjacent circles of pointed drive teeth and with an associated viewing window for display of day and date side by side. A rotary index pawl coupled to the drive train by a one-way intermittant motion transmitting connection produces an active stroke of movement once every 24 hours. Detent springs for the respective rings engage the drive teeth for completing each step of indexing movement. A manual reset lever is separately engageable with the respective rings for indexing the rings individually into set positions. The nature of the drive connection permits indexing of the rings by the manual reset lever at any time regardless of the position of the index pawl.
