ABSTRACT:
A glass delivery system including a first forehearth having an orifice, a second forehearth having an orifice, a bottom pan assembly adapted to be positioned underneath the orifice of the first forehearth, and a glass delivery tube having an upper end adapted to be positioned underneath the orifice of the second forehearth and a lower end adapted to deliver glass to the bottom pan assembly. The orifice is adapted to combine the glass from the two forehearths and, deliver cased glass to provide an interior glass from said first forehearth and an external layer of glass from said second forehearth. Provision is made for moving the glass delivery tube horizontally, vertically and in azimuth relative to the second forehearth and for moving the bottom assembly relative to the first forehearth. The glass delivery system includes a first carriage system that supports the delivery tube assembly for movement horizontal, vertical and azimuth directions and a second carriage system on which the bottom pan assembly is mounted with respect to the first forehearth formoving the bottom pan assembly for horizontal movement relative to the first forehearth.
