This might be it. A hinge for crates that allows the lid to be slipped off of the box.

Close, but I think 259,558 is closer. (The '558 patent drawing is shown 90-deg opposite from the photo.)
"Jgas'" photo is missing the c' pin of the '318 patent, and has what looks to be the electrical contacts of '558, instead of the screw holes shown on '318.
That said -- to me, it's not conclusive either way.
Having the patent mark on the clip itself would seem to make more sense for the '318 patent (as THAT is the essential part), whereas on the '558 it is less clear that the contacts are the essential part of the invention (i.e, the clip itself and not the panelboard arrangement of said clips).
And just to fully flush it out, we're all assuming the year is 1882, and patented in the United States.
Reasonable assumptions, yes - but not necessarily so.
