Abstract
1433439 Alarm watches TIMEX CORP 27 June 1974 [5 July 1973] 28672/74 Heading G3T In a watch comprising an alarm membrane, e.g. crystal 10, including a pin 14 which is repeatedly struck by a tongue 36 when an electromagnet coil 44 is energized, the electromagnet is mounted on a support arm 32 one end of which is fixed to the watch framework and the other end 32' of which is adjustable e.g. by a screw 56, and the tongue has its one end fixed relative to the arm 32 and its free end adjustable relative thereto by an arrangement which acts with motion reduction upon the tongue near its clamped end. As shown the arm 32 and a lever 34 are attached to a mounting block 22 by means of a screw 38 and a bush 40 which also holds the tongue 36, the block 22 being fixed to watch plate 20 by a screw 26. A pin 42 is freely slidable in a bore 30 in the block 22 and transmits movement of lever 34, when screw 64 is adjusted, to the tongue 36. The tongue can thus be accurately pre-adjusted relative to the electromagnet, and the whole assembly adjusted relative to the pin 14 by means of the screw 56 after assembly in the watch. Other embodiments show different ways of adjusting the deflection of the tongue.
