Abstract
A doll with an eyeblink mechanism includes an eye with a reciprocatable eyelid, a drive providing intermittent slow rotary motion, and a torsion spring for accumulating such rotary motion, as necessary, and converting each predetermined quantity of such rotary motion into intermittent, relatively rapid reciprocating motion of the eyelid to blink the eye. A safety mechanism precludes overwinding of the torsion spring, e.g., when movement of the eyelid is physically blocked.
