Another possibility... Some older pieces of farm equipment such as grain drills had rings connected by lengths of chain that were drug behind the machine. Usually there was perhaps a foot of chain connected to a ring such as the one pictured, then another foot of chain and another ring. The function was to help cover the wheat or other grain being planted.
