摘要： The place shift-up mechanism of a digital clock comprises ratchet feed mechanism which permits manual setting of the clock even during the shift-up operation. The ratchet feed mechanism comprises an eccentric cam secured to a rotary shaft which also carries an eccentric operation pin. A ratchet wheel is rotatably supported by the shaft. A place shift-up lever is supported so as to be capable of rocking and sliding movement and has a forked leg plate with spaced legs receiving the eccentric cam between them. One leg of the forked leg plate has a feed pawl for engagement with the ratchet wheel and also a hook pawl engageable by the operation pin to move the place shift-up lever in one direction. The other leg of the forked leg plate has a return pawl which is engageable by the operation pin to move the plate shift-up lever in an opposite direction. The place shift-up lever is rocked by the eccentric cam and is moved by the operation pin first in one direction and then in the other to cause the feed pawl to engage the ratchet wheel to advance it one tooth for each revolution of the rotary shaft.

摘要： An operation member slidably supported on a base plate has opposed pawls which are spaced apart and project toward one another. A position control cam and an integral supplementary cam are rotatably supported on the base between the two pawls. The pawls are disposed on different planes so that a first pawl is engageable with the control cam and the second pawl is engageable with the supplementary cam. The operation member is spring biased in a direction to move the first pawl toward the position control cam. The position control cam is provided alternately with deep concaves and shallow concaves. When the first pawl of the operation member engages in a deep concave it is in one position. When it engages a shallow concave it is in a second position. The supplementary cam has teeth at positions corresponding to the concaves of the position control cam. When the operation member is slidably moved in a direction opposite to the spring bias, the second pawl engages a tooth of the supplementary cam so as to rotate the supplementary cam and the position control cam to a new position. For example starting with the first pawl in a deep concave, sliding the operation member against the bias spring causes the second pawl to engage a tooth of the supplementary cam and thereby rotate the cams so that when the operation member is released the first pawl engages in a shallow concave of the position control cam and the operation member is thus in a different position.
摘要翻译： 可滑动地支撑在基板上的操作构件具有彼此间隔开并且彼此突出的相对的棘爪。 位置控制凸轮和一体式附加凸轮可旋转地支撑在两爪之间的底座上。 棘爪设置在不同的平面上，使得第一棘爪可与控制凸轮接合，并且第二棘爪可与辅助凸轮啮合。 操作构件沿朝向位置控制凸轮移动第一棘爪的方向被弹簧偏压。 位置控制凸轮交替设置有深凹陷和浅凹陷。 当操作构件的第一棘爪啮合深凹时，它处于一个位置。 当它接合浅凹时，它处于第二位置。 辅助凸轮在与位置控制凸轮的凹部对应的位置处具有齿。 当操作构件在与弹簧偏压方向相反的方向上可滑动地移动时，第二棘爪与辅助凸轮的齿接合，以将辅助凸轮和位置控制凸轮转动到新的位置。 例如从第一棘爪开始在深凹部中，使操作构件抵靠偏置弹簧滑动，使得第二棘爪接合辅助凸轮的齿并由此旋转凸轮，使得当操作构件被释放时，第一棘爪接合 因此，位置控制凸轮和操作构件的浅凹部处于不同的位置。

摘要： A simulated pendulum clock has a pendulum which rocks to and fro for decorative purposes only thereby simulating a pendulum clock of the type having a rocking pendulum for timekeeping purposes. A transmission wheel is rotationally driven by the timepiece movement of the clock and a friction clutch mechanism transmits the rotational movement of the transmission wheel to a rotating member whenever the load on the rotating member is less than a predetermined value and otherwise enables slipping of the transmission wheel relative to the rotating member. A toothed escape wheel is coaxially mounted with the rotating member and is connected thereto through a coil spring which applies a rotating torque to the escape wheel. The teeth of the escape wheel coact with a pair of pallet pins of a pallet which is mounted to undergo rocking movement in response to alternative engagement and disengagement of the pallet pins with the escape wheel teeth. A pendulum is fixedly secured at one end to the clock case and hangs downwardly therefrom in juxtaposition with the pallet, the pendulum being connected to the lower end of the pallet so as to transmit the rocking movement of the pallet into a rocking two-and-fro movement of the pendulum thereby simulating a pendulum clock.
