ABSTRACT:
A batch charger for a molten glass furnace comprising a stationary hopper having an inlet opening at the upper end and an outlet opening at the lower end. A reciprocable charger plate located below the outlet opening of the hopper to supply material from the hopper to the furnace. The charger plate has a bottom wall and upstanding sidewalls at the edges of the bottom wall which are outwardly spaced from the sidewalls of the hopper. An adjustable seal is attached to the rear wall of the hopper with a lower edge located below the lower edge of the rear wall of the hopper and depending flapper members are pivotally attached to the front wall of the hopper at each edge to prevent loose material from passing between the sidewalls of the charger plate and the sidewalls of the hopper when the charger plate is reciprocated.
