Abstract
A method of and apparatus for feeding glass making materials into the forward end of a continuous glass melting furnace whereby the melting rate of the materials is increased. In accordance with the improved method, the glass making materials are continuously deposited on the molten glass bath in the doghouse of the furnace, periodically compacted to remove entrapped air therefrom, and advanced into the furnace while thus compacted. The apparatus has a reciprocating pressing member which is periodically advanced from a rest position in a raised attitude over a transverse row of newly deposited glass making materials, lowered to compact the materials between it and the surface of the molten glass bath, and advanced in its lowered attitude to move the compacted glass making materials into the melting end of the furnace.
