  • Patent number: 6755567
    Abstract: To provide a hand motion irregularity suppressed timepiece whose ability has been improved. As to a spring having a flat portion and a bent portion, the flat portion is disposed between a second chronograph wheel and a center wheel, and the bent portion is sandwiched and supported under a pressurized state by a train wheel bridge and a bottom plate. By this, the spring portion prevents a hand motion irregularity of the second chronograph wheel by the fact that the second chronograph wheel is pressure-contacted with the train wheel bridge. Further, by forming a gap between the second chronograph wheel and the center wheel, an accompanying rotation between the second center wheel and the center wheel is prevented.

  • Patent number: 4629331
    Abstract: A windable clockwork for metronomes comprises a clockwork frame, a stem rotatably mounted in this frame, a spiral spring connected to this stem, a housing enclosing the spring, and a blocking mechanism which prevents the stem and the spring from reverse motion during the winding. The blocking mechanism comprises two coaxially arranged parts made from a plastic material, namely a locking disc and a spring disc. One of these parts is stationarily arranged on the frame and the other is connected to the stem. The locking disc comprises at its periphery at least one integrally formed stop and the spring disc carries at least one likewise intergrally formed, resilient tongue which in one rotational direction of the stem glides elastically past the stop, but in the opposite rotational direction abuts the stop and blocks the reverse motion of the stem and the spring.
