Abstract
An apparatus for charging an electric glass furnace having a bottom, first and second opposing sidewalls, and first and second opposing end walls. The apparatus includes hoppers for receiving glass batch from a source and for discharging the glass batch into the furnace. Each of the hoppers has an upper inlet end and a lower outlet end extending along the upper edge of one of the end walls of the furnace. One of the hoppers extends inwardly from the first sidewall along the edge and the other one of the hoppers extends inwardly from the second sidewall along the edge with the hoppers spaced from each other along the edge. A pusher drum, rotatable about a substantially horizontal axis, is associated with each of the hoppers. Each of the drums is parallel to the edge but spaced therefrom with the outlet end of the associated hopper therebetween. The drums are substantially axially aligned and axially spaced from each other and from the respective sidewall from which the associated drum extends. Each of the drums is substantially coextensive with its associated hopper except for the spacing from the respective sidewall. Upon rotation of the drums, the glass batch from the hoppers is c…
