Such a crank wheel 18 on the shaft 19, which is provided with a pivot pin 20 from the Swiss patent specification. Known at this turning 364 459. The known switching device is a so-called 45 of its to-and-fro movement of a fixed Zap quick-action, in which the date ring is guided into the pound 22, which is inserted into the slot 23 of the courses between the switching steps should stand still; to belstange. In this way locking means are provided for this purpose. When the crank wheel 18 moves back and forth in twenty-four hours, a movement of force is converted into a force movement, with two springs serving on the outer circumference being pretensioned, the projections 24 then arranged on the connecting rod 21 and, when unlocking, a lock on the date ring 25 turns with each revolution of the crank wheel 18 in Einum half a step, after which a pawl is reached with the teeth of the star wheel 3 and causes the remaining rotation. move this further by a seventh of a turn, the object of the invention is to provide a switching device as in the position shown on the tooth 6 device of the type mentioned, 55 of the star wheel 3 can be seen.
which hardly gets by with very few, the overall height of the work due to the arrangement of two projections 24 and enlarging individual parts and at the same time 25 on the connecting rod 21 the star wheel 3 can be actuated in one, if not abruptly, but in both directions, so that when First of all, as a quick step, resetting of the clockwork enables the star wheel to be reversed. 60 th direction is moved on, as it is, for example. This object is achieved according to the invention when the date line is exceeded from west to that the other end of the switching element is required exzen-east.
