K8041 - Time switch for the fan

Brrriiiiiiiing! Time to wake up, in the last century! In an age before cell phones and digital alarms there once was a fantastical device called an alarm clock, with two bells mounted on top that were struck by an oscillating hammer. You would wind the clock with a ratchet key, set the alarm hand for the time you wanted to wake up, and when the clock\'s hour hand caught up to the alarm hand those bells would ring for all they were worth, until you turned it off or flung it against the wall (a one-time snooze option)! Can you believe such an amazing, simple-yet-ingenious mechanism ever existed? UGears 70163
