This "milk carrier" was designed in 1893 by a small Jura company in Saint-Lamain to bring down the cans of milk (milk balls) from the two milkings of the day for the manufacture of Comté cheese, from the hamlet of Chaumois-Boivin to the village of Blois-sur-Seille, where the cheese factory was located. Five hundred metres of cable and two hundred metres of difference in altitude. There was no engine: the basket containing the full balls that went down allowed the basket with the empty balls to go up. A simple and very ingenious mechanism enabled it to operate from 1893 until the closure of the cheese dairy in 1982.
