Abstract

Mécanisme de quantième annuel ou perpétuel simple pour une pièce d'horlogerie, de nature rotatoire et possédant un faible nombre de composants, dont une roue de quantième (1) co-axiale à une roue fixe (4). Une roue des vingt-quatre heures (3) entraîne la roue de quantième dont la rotation permet à une roue des années à douze dents (8) - et, dans sa forme perpétuelle, à une roue bissextile (17)-d'être entraînée par la roue des vingt-quatre heures et ainsi d'avancer la date pour l'ajuster aux mois courts.

Figure imgaf001
Simple or perpetual calendar mechanism for a timepiece, rotatory in nature and having a small number of components, including a date wheel (1) coaxial with a fixed wheel (4). A wheel of twenty-four hours (3) drives the date wheel, the rotation of which allows a wheel of years twelve teeth (8) - and, in its perpetual form, a leap wheel (17) - to be driven by the twenty-four hour wheel and so to advance the date to adjust it to short months.
