So it keeps something from closing - or only lets it close a certain amount? ETA: I got no freakin clue!
And that's where I'm stuck. The fork part looks so much like a water meter key that I can't get away from that thought. I need to get away from that thought b/c water meter keys ain't precise instruments!
A hinge for a toilet seat lid? I'm guessing a screw with wing nuts or a nut and bolt slide into each U-shaped area for fastening?
It kind of looks like metal jaws, doesn't it? I think it is some kind of brass dental articulator like this . . .
