Antique lock

Quote: kenarman

You likely have to take both door knob faceplates off as well Paco. There is likely 2 through bolts hold them together that also pass through the latch mechanism. The through bolts likely can be unscrewed from the non-secure side of the door.

Bingo. I didn't remove one of the 2 "through bolts" because it was just spinning like it was stripped. I took it out with a pair of tweezers. Then the cylinder with the key just unscrewed.

The final result looks like this!


The closest I could find on the web was a 100 year lock The Mortise Falcon. This design was also a Rosswin lock, but I think my lock is about 85 years old, and is a modified design.



In the bloggers case it was a broken pin (1) in the photo.


I don't seem to have the exact same problem, so I still have to debug.

It is amazing how they built things in the pre-electronics age.

I suspect it is that spring a third of the way up from the bottom (it looks like a hairpin). I only say that because it is not connected to anything. I wish I knew how it was supposed to look.

They would say it's amazing how we build things.
It's not that they built things to last, their
way of doing it made them last a long time
naturally. Brass and iron and steel tend not
to wear out real fast.
