Re: 38 Packard Clock - Need Pics

There's more than one basic mechanism and shape depending on size and style of clock. Packard didn't really identify by a Borg number. Here is a 46 Borg round style which appears to be identical to the prewar clock posted earlier. Probably similar to what you have but then maybe not. Pictures may not be enough detail but it's a working clock so don't want to tear it apart farther.

The contacts close and pull the wind arm even with the end of magnets. That puts tension on the straight spring which starts to pull it back and provide the "spring" to the clock. As the spring pulls the wind arm near the slack end of it's arc, a pin attached to the wind arm moves the "Y" shaped piece just above it and snaps the contacts closed. The magnet energizes and almost as soon as the wind arm starts to move back toward the magnet end it snaps the contacts back open.
