ABSTRACT:
In a striking clock having a striking mechanism, a release lever for releasing the striking mechanism to cause a striking of the clock, a barrel cam associated with the release lever for moving the release lever to release and retain the striking mechanism, a clockwork for rotating the barrel, and a lock disk driven one revolution in 24 hours by the clockwork, a device is provided for disconnecting the striking mechanism at any time, selectively and/or temporarily. The lock disk has a sector type lock cam which extends over a distance corresponding to about a 10 hour period on the lock disk. A feeler lever engages the lock disk and is moveable from a release position to a stop position when the feeler lever encountered the lock cam. A lock lever is couplable to the feeler lever and engageable with the release lever for moving the release lever to retain the striking mechanism when the feeler lever is in its stop position. A coupling lever is associated with the lock and feeler lever for selectively coupling and uncoupling the lock and feeler lever. A manually adjustable switch lever engages the coupling lever for moving the coupling lever into its uncoupling position at any time so that the striking mechanism can be released at any time, even when the feeler lever is engaged with the sector type lock cam of the lock disk.
