I'm working a 1913 GB clock...it's the one in this post:
My Collection has Grown!
It has not run since I got it, and early on noticed something unusual about the anchor and escapement. I'm finally getting around to it. I was thinking that I might discover some reasons when I cleaned and reassembled.
What I'm noticing is that anchor pin never comes past the vertical position as I manually operate the anchor with my finger. The pin stays completely to the right of center as you look at the back of the clock. I guess that's going to be a problem, right?
The anchor pin points straight up when the anchor sits on the bench. As near as I can measure, the pallets are exposed the same amount which results in the pin pointing straight up. Nothing is bent. I'm getting good movement of the train...the EW takes off with just a few clicks of the main spring. I thought that maybe the anchor bushing and the EW bushing weren't on a vertical line, but that doesn't seem to be the case. The locks and drops appear to be reasonable, but I haven't really looked that deeply yet.
What controls the position of the anchor pin? AFAIK it should move about 4 degrees each side of center for proper operation. I'm not anywhere close to that. What should I be looking for? Here's a picture of the eccentric slot...pretty well abused. I don't know if this is where I need to be looking.
Thanks...Kurt
