Answer
I'm not sure about what your questions are about, but, I will take a shot anyway.  I don't know what you mean be chain rings,  I will guess you mean chain hangers.  These pieces are sort of flat egg shaped brass stampings.  There should be a total of six of these.  All would have a hole pierced into the small end.  Three of these pieces have no hole or hook stamped into them.  These three will go onto one end of each chain.  To attach to the chain simple open the last link, insert the link into the hole and close the link.  The other end of the chain is used for hanging the weights.  Two of these remaining hangers are formed into circles, you insert the hook on the weight shell into theses holes.  The remaining chain hanger is formed into a hook and you run this through the hole at the top of the remaining weight.  Now as you face the clock the chain with the hook and circled end on the heaviest weight mounts on your don't as you face the clock.  The other two are of the same weight so it make no difference what one you put into what remaining position.  Now as to the position you pull the weights to, never bring them closer than two inches below the seat board.  (the slotted board the movement sets upon.  I sure hope i have answered your question, if not, it has not been for not wanting.  Regards WJP
