ABSTRACT:
A signal device signals cycle changes in a dryer by sounding a bell assembly upon acceleration and/or deceleration of the motor shaft. When the rotational speed of the flywheel is synchronized with the rotational speed of the motor shaft there is no striking contact between the bell assembly and the clapper of the flywheel assembly. A one-way spring clutch is employed to limit signaling to either acceleration or deceleration of the motor shaft. The device also may be constructed in a reverse manner, with the bell acting as a flywheel journaled on the shaft and the clapper assembly rotatable with the motor shaft.
