Description

Arrangement on master clocks, which at every power surge to the slave clocks to be wound up again The invention relates to a leash arrangement on master clocks, which are wound up again with each power surge to the slave clocks.

There are master clocks known in which the slave clocks during the Lowering of the watch weight, whereas with: the actual Elevator process, the switching circuit for the slave clocks is only interrupted. Such an arrangement precludes it as a means of storing the consequent due to a malfunction (e.g. power failure) Continuous current surges simply to use the watch weight, which in the event of a malfunction by one of the sum of the incremental pulses that did not take effect. Amount goes down. On the other hand, master clock systems have become known where the elevator electromagnet and the slave clock switching magnets are arranged parallel to one another are switched on at the same time and for the same length of time through a common contact will. This causes a very% undesirable operational uncertainty in clock systems, because it can happen with the parallel connection that either only the elevator magnet or only the slave clock switching magnets respond, which causes the clock system to go wrong has the consequence.

The aforementioned disadvantages are eliminated according to the invention by that the contact formation for the slave clocks mechanically from the movement of the armature of the winding magnet of the master clock is derived in such a way that this contact is only is possible as soon as the elevator magnet executes the desired elevator movement.

The elevator magnet directly operates the contact for the slave clocks with any power development, while with known versions of the normal clocks with spring or weight winding the slave clock contact device by its spring or a. Weight is actuated, with which a drive is mediated only one determined by the size of the wind wing or other braking organ Force can be transmitted to the contact.

The invention is shown in an exemplary embodiment on the drawing illustrated schematically.

The mode of operation of the contact device for slave clocks is described below described on a known embodiment with pole reversal, wherein: the winding shaft 9 of the master clock over ratchet wheel 7 by gears with the contact cam i o in connection stands. If the contact cam io is now rotated into the position denoted by i2, then thereby making contact with the right contact spring i i. At the next Movement of the pull-up magnet will then move the contact cam into the position indicated by 13 Position moved, whereby the slave clock circuit is interrupted. The next Position of the contact cam, which is denoted by 14, is with the left contact spring i i contact, so that the slave clocks receive power again in this position. at the next switching movement comes the contact skirt again in the position 15, whereby the contact is broken again. Since the two contact springs i i to different Poles that are connected to a power source are to be thought of as -will at every contact position also causes reversal of the current at the same time.

Claims (1)

PATENT CLAIMS: i. Arrangement of master clocks, which at each power surge to be wound up again somewhat on the slave clocks, characterized in that the Contact formation for the slave clocks mechanically from the movement of the armature of the winding magnet the master clock is derived in such a way that this contact is only possible as soon as the elevator magnet executes the intended elevator movement. z. Arrangement according to claim i, characterized in that after the failure causes cease to exist in a known manner the memory device automatically brings the slave clocks to the correct position.
