Milk Cans Loaded by Gravity Power (Sep, 1931)
Milk Cans Loaded by Gravity Power
GRAVITY, without assistance of other power, is employed by a chocolate factory in England for the loading and storing of milk cans. After being elevated by an endless chain to the top of the tower the cans spiral down a roller track to the bottom, where gravity holds them always in readiness for loading and feeds them onto the truck backed up to the receiving platform. The spiral stairway is shown in the photo above. The spiral acts as a store house before cans are loaded.
