Abstract

Mechanical device indicator of the days and months, for calendar clocks, characterized in that it comprises a motor shaft that turns every twenty-four hours and is coupled by an intermittent transmission of thirty-one to one ratio with a daily wheel and with a regulating wheel, the first of which has an initial position corresponding to the first day determined by cooperating stops of the same and of the support structure of the mechanism, said regulating wheel presenting a stop in relation to which a rotor having several stops is provided, each of which is able to be arranged within the trajectory of said stop of the regulating wheel, in ca apposition of said rotor, including in relation to said daily and regulatory wheels means of action antagonistic to said driving shaft capable of causing the displacement of the same in the opposite direction of return, said motor being related to a single-effect ratchet mechanism whose already nails are mounted eccentrically on a common nail to two ratchet mechanisms whose respective toothed rings are integral to the daily wheel and the other to the regulating wheel, these two ratchet mechanisms being antagonistic to the means capable of causing the return of both wheels, said regulating wheel presenting a thrust stop of this common nail to both mechanisms, capable of causing its displacement to a releasing position of both wheels, including means capable of keeping said nails disposed in a meshing relationship with the respective toothed crowns.
