Any Ideas What This Is?

I was going through my “not obvious trash but not obvious treasure“ pouch and pulled out both of these. After a little cleaning, I can tell the item on the left is a lamp wick holder. It says EF Jones patent May 4–55 Reissued Jan 11 59.  The first year may actually be a 57. According to the Internet, that matches with the EF Jones January 11, 1859 patent.  The place where I found it has a small museum. I plan to take it back to them and see if they want it. The second item I really have no clue about. The end of the main wire not connected to the circular object has small wire wrapped around it – possibly part of a spring.

My first thought from the shape was some sort of suspender clip but since the wire is not connected on both sides that can’t be.  Since the central object is brass it can’t be some sort of a sparker.  I also considered some part of a doorbell, but this has me stumped. 🤔  Any ideas?

Thanks!
