    • A slip mechanism in the gear train of a clock comprises a gear wheel and an associated pinion coaxial with the gear. The gear wheel and pinion have interengaging surfaces for centering and rotatively guiding them relative to one another. A circle of resilient fingers on one of the gear wheel and pinions resiliently, frictionally and radially engage an annular friction surface of the other to provide a frictional coupling between them. Moreover hooks on the fingers retain the gear wheel and pinion in assembled relation to one another. In one embodiment the resilient fingers are integral with the pinion and are received in a concentric opening in the gear wheel of lesser diameter than a circle defined by the fingers in relaxed conditions. In another embodiment the resilient fingers are integral with the gear wheel and engage the outside of a concentric flange on the pinion of larger diameter than a circle defined by the fingers in relaxed condition. The pinion and gear can readily be formed of plastic material thus providing an inexpensive slip mechanism which can be easily assembled.
    • 时钟齿轮系中的滑动机构包括齿轮和与齿轮同轴的相关小齿轮。 齿轮和小齿轮具有相互接合的表面,用于对中并相对于彼此旋转地引导它们。 在齿轮和小齿轮之一上的弹性指状物的一圈弹性地摩擦和径向地接合另一个的环形摩擦表面,以在它们之间提供摩擦联接。 此外,手指上的钩子保持齿轮和小齿轮彼此组装的关系。 在一个实施例中,弹性指状物与小齿轮成一体,并且在松弛条件下被容纳在比由手指限定的圆直径小的齿轮中的同心开口中。 在另一个实施例中,弹性指状物与齿轮成一体,并且与松弛状态下由指状物限定的圆形直径相比小齿轮上的同心凸缘的外侧接合。 小齿轮和齿轮可以容易地由塑料材料形成,从而提供便于组装的便宜的滑动机构。

    • A time detecting switch for a time signalling clock having a time wheel and detecting wheel both rotatably mounted coaxially and a phase detecting type slide switch between the time wheel and the detecting wheel comprises one of the wheels comprising an electrically conductive hub having a flange with a radial contacting surface at one end of the hub, an insulating disc and a sectoral switch plate around the hub, the disc being sandwiched between the plate and the flange with the plate being mechanically and electrically connected to the other end portion of the hub facing the other wheel. The other wheel has a sliding contact for contacting the sectoral plate and the radial contacting surface of the flange is capable of maintaining uninterrupted continuous sliding contact with the signalling circuit of the clock.

    • In a timepiece having a case and having a minute hand and an hour hand for indicating time, an alarm signaling device generates an alarm by detecting the phase of two sets of gears. One set of gears comprises an hour hand gear and an hour detecting gear and the other set comprises a minute hand gear and a minute detecting gear. The two sets of gears are concentrically mounted for rotation and the minute detecting gear is positioned between the minute gear and the one set of gears. The minute detecting gear has a contacting sliding contact with the minute gear. The alarm signaling device further includes an alarm signaling time setting wheel having an axis of rotation parallel to that of the two sets of gears and a first gear and a second gear engaging the minute detecting gear and the hour detecting gear respectively.
