Looks like some leftover from a slavetrader

I agree. Looks like shackles.

No and No, this is in Michigan waters, we did not have slaves in the North.

Well, it would appear that the two rings, being attached to the spikes would have been anchored into the ship. They are connected by a short length of chain. Only reason I can think of for something like that would be to secure somebody, by way of a set of shackles, in a brig.

not shackles, no way to open/close them

Is chain connected straight across, or just by loop?

OK, didnt see next pic

It looks like iron boom dogs used in timber rafts.

Something to do with horses?

It is a mountain climbing rappel anchor. Don't know why it would be in a Lake up there, but I have seen a few exactly like that up on El Cap in California. Two Pitons, each with a metal ring for your rope to go through and with a connecting chain for safety, should one of the pitons come out.
