Help identify these?

[Zugmaschine]

First off I want to apologize for the poor pictures but I tried my best, anyway I found these in the dump I was digging that dates back to the 1840's I don't think these are that old. But I have no idea what they are the one has a solid piece of glass in it, and they seem to be made out of tin/copper/brass i don't think its bronze but i could be wrong. I would just like some help identifying them so i could kinda figure out what was back there at that site.

Thanks guys.

Those two things right to left belong to a back of a brass door knob and the piece on the left is the door hole cover for the door knob. The other two I can't say.

The object with glass in the end looks to be the end of some type of light bulb. ???? Possible automotive.

I agree with Elton. Looks like the base of an auto/truck indicator bulb. It doesn't have the usual side lock-in pins though. Might have been secured another way.
