OH! I SEE! (I'm new to this) When the pendulum slows down enough, the little swinging arm activates a switch which energizes the big electromagnets to give the pendulum a push, then get out of the way. And that's just the beginning of this amazing mechanism! Fifty more views and I'll have it...
Hi, Exactly! The little lever is called a Hipp toggle and it has a V-Block just below it fixed on top of the electrical contacts.These act as a mechanical switch connected to the big electromagnets. When the pendulum arc drops below the point where the toggle can no longer clear the block it pushes down on the V-block closing the contacts. The powerful magnets then attract the hinged armature and gives the pendulum a good hard push. The pendulum then swings free for another minute or so.
Hi John, Many thanks for your kind comments. I intend to build a simple steadycam to improve my camera control. A fixed tripod is a little too static but using a hand-held camera far more difficult than I imagined. Using the hanging weight of my massive video tripod was simply too much and had far too much moment when I wanted to change direction. Did you click on "more info" over on the right of my video page? I have a simple blog on my Gent's turret clock. Click on my user name for a link.

Are you with Smiths?
