CLIQUET POUR MINUTEUR

ON PEUT FAIRE TOURNER MANUELLEMENT L'ELEMENT DE MINUTERIE PAR RAPPORT A L'ELEMENT D'ENTRAINEMENT EN RENCONTRANT DANS LE SENS DE ROTATION G UN PLUS GRAND COUPLE RESISTANT QUE DANS L'AUTRE SENS V. UN ORGANE D'ENCLIQUETAGE ENGRENE AVEC UNE DENTURE INTERIEURE PAR DES DOIGTS 7, 8, 9 DE BRAS 4, 5, 6. LES PROFILS DE DENTS DE LA DENTURE INTERIEURE PRESENTANT UNE SYMETRIE ANGULAIRE PAR RAPPORT A SON RAYON, TANDIS QUE L'UN DES PROFILS DE DENTS DU DOIGT 7, 8, 9 FAIT AVEC LE RAYON UN ANGLE PLUS AIGU QUE L'AUTRE PROFIL DE DENTS. LE BRAS 4, 5, 6 COMPORTANT LE DOIGT 7, 8, 9 PRESENTE, SUR TOUTE SA LONGUEUR, UNE MEME SECTION DROITE ET FLECHIT ELASTIQUEMENT LORSQU'ON REGLE MANUELLEMENT L'ELEMENT DE MINUTERIE. An escapement or directional latching mechanism for a timer which actuates a timing switch component through the intermediary of a driving member, which is manually settable relative to the driving member against a larger moment of resistance in one direction of rotation as in the other direction of rotation. The escapement includes a ring having an internal toothing coupled with the driving member, and a ratchet wheel connected secured fixed against rotation with the timing switch component and which is located coaxially with the ring, with the ratchet wheel including at least two arms located in the plane of the ring, which with a finger thereof engage spring-elastically in the radial direction into the internal toothing, and which finger upon a displacement in one or the other direction of rotation is forced out of engagement with the internal toothing, whereby the pairing constituted of the internal toothing and the finger is provided with on the first pairing portion with tooth sides which are angularly symmetrical relative to the radius of the ring.
