    摘要： Timepiece wheel set with a unidirectional wheel rotating in only one direction in cooperation with a ratchet wheel, which is movable inside a ratchet wheel chamber, comprising a click that rotates integrally with this wheel, which forms a one-piece component comprising at least one spring-arm, at the end of which, on a first side, a beak cooperates directly with the toothing of a ratchet wheel in an operating position in which this spring-arm is free, and on a second side, a first hook can cooperate with a second hook of complementary shape, comprised in this one-piece click, in a rest position in which this spring-arm is in an extended position, the elasticity thereof allowing this first hook to be hooked or unhooked with respect to this second hook by the action of an operator, by maximum elongation of this spring-arm and/or by the tilting of this end.

    摘要： This unidirectional correction arrangement (1) for a display device exhibiting a circular element (2) provided with teeth (3) includes a cylindrical element (4) around which is wrapped a helical spring (5), one of the ends of which serves as a finger (6) adapted to come into contact with a tooth (3). When the cylindrical element (4) is driven in rotation in a sense (A) for which the force (F1) exerted on the finger by the tooth is directed in a sense tending to wrap the spring around the cylindrical element and to tighten it therearound, the circular element (2) rotates. Such circular element (2) will not be driven when the cylindrical element (4) is driven so as to rotate in a sense (B) for which the force (F2) exerted on the finger by the tooth is directed in a sense tending to open the helical spring.

    摘要： A second jumper spring made of a resilient wire is bent at its one end for engaging a fourth wheel or a ratchet-toothed wheel for driving a second hand. The second jumper spring is fixed at the other end on a pin rotatably mounted on a mounting plate which is horizontally movable. The second jumper spring is turnably mounted on the mounting plate and horizontally movable therewith to regulate the fourth wheel or the ratchet-toothed wheel for driving a second hand.

    摘要： A device for unidirectionally blocking a ratchet wheel, comprising a unique blocking organ having on the one hand retaining means co-operating with stop means formed by stationary parts of a clockwork movement and, on the other hand, a tooth and a disengaging means, both of which co-operate with the toothing of said ratchet wheel, advantages resulting mainly in the automatic mounting of the device.
