Abstract: Two molds attached to the same carriage and filled with molten glass in the form of a gob, are presented by a roller track from beneath a pair of blowing spindles or pipes with which the molds are nested until the glass therein is fixed or set in the clamping means of the spindles, after which the molds disengage from the parisons attached to the spindles by a descending portion of the roller track which guides their carriage. The carriages are moved along the roller track by an endless chain conveyor synchronized with the movement of the glass forming machines carrying the pair of blowing spindles. The parisons attached to the spindles are then formed and blown into the containers in the normal manner of that of a "Westlake" turntable type of glass container making machine.
