Anyone know what this chain setup controls?

The mechanical lubricator for the front engine. The sprocket on the left is on the Nathan lubricator. Note the sight glass to inspect the oil level.

The chains were a UP modification. The original long actuating lever proved not to be up to the rigors of everyday operations. The chain drives were fitted with covers, somewhat like the chain guard on a bicycle.

Why they haven't yet been replaced on 4014 is anyone's guess.
