Look like rail lubers to me. I have seen them mounted on top of guide rails on 1920's jobs. I bet the flex has a small hose in it running down to the rails.

Those are oilers alright. Almost all I've seen had copper tubing run to the rails. By the way that floor looks great who sanded off years of grease and oil????
