Found 5/30/16 cannot identify

[VaMike]

I found these four items while detecting what is now a park. The history of the park is great though. There was a CSA camp in the general area. I have no clue what three of the four items are. I think one is the internals of a clock. If anyone can help me I'd appreciate it!
Oh and the one item has a patent date on it of June 16, 85

You can look through these to check the patent for June 6, 1985. The clock piece is all that I recognize.

Rectangular piece looks like a reed for a squeeze box with the reed gone. Look and see if there is a letter on one side or the other...d2
