I recently started working on an antique mechanical Jennings Sweepstakes Chief 5c slot machine. I watched Dave's videos on youtube for how to unjam the machine (super helpful!). However, the machine continues to jam about half-way through a lever pull and I always have to unjam the machine. I cleared the escalator and checked to see if there's nickels anywhere and the problem continues to occur. I've noticed two things:
1. It looks like a spring is missing. But I'm not sure how important it was. The bracket that should hold tension on two springs has the left tooth broken off:
2. The escalator is very difficult to manually advance and I'm wondering if the problem is the escalator isn't advancing with the pull of the lever.
Here's a picture of the lever half-pulled and jammed:
I would really appreciate it if anyone could point me in the right direction!
