A questioner said:

Found these at a flea market. The metal pieces are riveted on. Any idea what these were used for?

More info:

There aren’t any obvious signs of wear on the wood, even though they appear to be quite old. There is no writing on either of them. They are about 6” square made from wood and metal. I thought they might be detachable handles of some kind, but there is no wear on the wood, just a nice patina from age.

Some of the comments:

No idea what the item is, but those aren’t rivets, they are what is called carriage bolts. The square bit below the bolt head presses into the wood and prevents it from turning as you tighten the nut.
Spool type things for winding yarn or something? This one is killing me because I swear I’ve seen them before!
Furniture removalists handles, puts a handle on a strap, or joins straps, lowers the friction so the strap doesnt burn the thing being strapped.
I’m thinking some kind of old tie down buckle for straps, antique rectangular d-ring maybe.
I’ve spent a ridiculous amount of time trying to figure this out. My last guess for now is some kind of shackle. I was thinking for a wagon or something, because of the wood and age, but still not sure. Resembles metal leaf spring shackles still used today.
Something in my brain says you put a 2×4 through each one and somehow make a temporary sawhorse or something…
They resemble modular inserts for a conveyor belt
Do the round pieces roll? Or are they static? From them being bolts, I imagine that they are static?
One side seems darker than the other and more worn. Seems handmade. My guess would be some kind of antique tie down tool. What we use ratchet straps for now. It looks like there is wear in the inside and edges of the wood like a rope has worn it away. Possibly a tire stand?
Used like a belt buckle for leather or rope to secure loads on old horse drawn carriage dont know name
they look like Fence pad locks
They look like an old tire store display stand. No wear on them that I can see.
Maybe some part of a hand-operated laundry machine?
I’ve seen similar things used for extending western saddle stirrups.
Maybe a carrier for something that’s not attached anymore. Firewood carrier. Horse tack carrier.
What do you think? Let us know in the comment!
