    摘要： 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.

    摘要： THIS INVENTION CONCERNS WITH A POSITIONING MECHANISM FOR A PRESSURE SPRING PROVIDED IN A TIMEPIECE MOVEMENT FOR EXERTING AN AXIAL RESILIENT PRESSURE ONTO A SECOND HAND ARBOR SO AS TO SUBJECT THE LATER TO A FRICTIONAL ROTATION IN COMPENSATION OF UNAVOIDABLE BACKLASH EXISTING IN THE RELATED GEARING. THE POSITIONING MECHANISM IS PROVIDED WITH A POSITIONING STATIONARY PIN OR THE LIKE PRESSURE-LIMITING MEANS PROVIDED ON A MOUNTING PLATE OR AN UPPER PLATE WHICH MEANS IS SO DESIGNED AND ARRANGED THAT IT MECHANICALLY COOPERATES WITH THE FREE END OF SAID SPRING FOR LIMITING THE FREELY MOVABLE RANGE OF THE SPRING END, AS WELL AS THE PIVOTALLY MOVABLE RANGE THEREOF IN ADVANCE OF FITTING THE SECOND HAND ARBOR IN POSITION IN THE TIMEPIECE MOVEMENT, SAID PRESSURE-LIMITING MEANS BEING, HOWEVER, NORMALLY KEPT OUT OF MECHANICAL CONTACT WITH THE SPRING DURING THE REGULAR OPERATION OF THE TIME PIECE MOVEMENT.
