THRESHOLD MOUNTED IN A MOLTEN GLASS DELIVERY APPARATUS JOHN E. SENSI and GEORGE O. WEHNER An apparatus for mounting a threshold in communication with a glass forming chamber containing molten metal includes a supporting structure and tension members for drawing the threshold against both the supporting structure and the inlet end of a glass forming chamber. The apparatus may also include outboard compression members for urging side members or jambs inwardly against the threshold. The entire assembly is easily removable for repair or replacement, yet a glassmaking apparatus including it is not subject to loss of molten metal due to separation of the threshold from the forming chamber during use.
