There is a shaft that runs through the blade hub to the rear of the motor and a cam and stops.   The feather rotates a half rotation and is stopped by the stops and cam on the rear of the motor which, after rotating more, releases the feather to make another half rotation.   I hope that's clear enough; I think the fan has a better understanding on how it works than I do.
Found some weathervane and lollipop videos:
