That is a container used to hold a lye solution to wash the milker claws, in this case 2 of them at a time.
The claw was suspended in a position similar to when you are milking and the milk hose is put on the spigot and lye is run into the claw until it fills up the claw. it worked great cleaning off milk stone.
