ABSTRACT:
A day and date indicator comprises a carrier structure which supports for rotation a flat, annular date disc and, within a recess in said date disc, a flat annular day disc. The inner peripheries of the two discs are provided with gear teeth that are adapted to be engaged by a cam driven by the clockwork mechanism and operative to advance each disc by a single increment once each day. The carrier structure is fabricated of a plastic material and includes resilient clamps and projections for attaching the carrier structure to the clockwork housing, integral resilient detents engaging the day and date discs to hold the discs in position when they are not being advanced by the cam, and a sleeve-like collar surrounding the indicator shaft of the clockwork mechanism for attaching the indicator to the housing of the clock. Each disc further includes a plurality of outstanding pins which can be engaged manually, or by a manually-operated setting mechanism, to set the two discs individually to desired indicating positions.
