Abstract
Disclosed are apparatus and method according to which a bell in a charging apparatus comprising a bell and surrounding hopper portion may be removed laterally out of the enclosure in which the bell and hopper are located, by removing a closure from an opening in the side of the enclosure that is aligned with bell and hopper portion, temporarily supporting said bell, disconnecting the bell from its bell rod and the hopper portion from its supporting means, and moving the bell and surrounding hopper portion laterally out of the enclosure. A bell and a mating hopper portion may thereafter be moved laterally into the enclosure into positions in which the bell can be connected to its bell rod and the hopper portion to its supporting means, the temporary supporting means is removed and the enclosure is closed. The disclosed apparatus also includes a lower bell and means for temporarily supporting the lower bell while it is disconnected from its bell rod after which the bell rod for the second bell is moved upwardly where it clears the upper bell, and its hopper so that the temporary supporting means for the upper bell and its hopper portion can be installed and the upper bell and its hopper disconnected to permit their removal.
