  • Patent number: 3980460
    Abstract: A glass batch feeder for an electrically-heated, glass-melting furnace is provided. The furnace typically includes a glass melting tank with electrodes immersed therein and with a batch feeder extending across the tank and movable back and forth from one end to the other to supply a layer of glass batch over molten glass in the tank. The batch is deposited gently on the top of the batch layer and in a positive, uniform manner to assure proper control of the thickness of the layer. The feeder includes a hopper and a rotatable distributor which intercepts batch from the hopper and deposits it in uniform increments onto the batch layer.
