Abstract

In an alarm clock a non-rotatable planet wheel 34, driven e.g. by an eccentric 21 secured to the minute spindle 16, and having 11 teeth, is processed within a ring gear 19 having 12 pegs 20 and connected to the hour hand 18, e.g. via its arbor 17, the alarm mechanism being actuated by a cam formed on or attached to the ring gear 19. An alarm setting wheel 25 has recesses into which cam portions 23, 24 enter at the set-alarm time, the ring gear being moved axially by a cantilever spring 31, the movement of which causes an end lug 34A thereon to release the alarm mechanism (not shown).
