Most probably a freewheel hub, although possibly a cassette system.
Either would have a cracked or eroded right side dust cap if it was
ridden much with a bearing problem.
Freewheels remove with a tool which holds the inner body and are
specific to the freewheel model. Cassettes of that era disassemble by
unscrewing the small gear. Either a more thorough description or a
consultation with a competent LBS would be helpful.
Do clean and inspect the cup inside the hub before going much farther.
If it was ridden loose for a while you may have damage there, the
bearing diameter being much larger after the cup erodes or cracks. I
couldn't tell from your description if it was a bearing cup problem or a
missing dust seal.
traditional threaded hubs look like this:

The freewheel removes completely
cassettes something like this:

the ratchet assembly is part of the hub, the sprockets slide off.
