ABSTRACT:
An automatic, rotary, glass-making press comprises a base, a rotary table mounted for rotation on the base, and glass-forming mechanisms on the table and base, for formation of glass articles at work stations around the press. A rotator is mounted for rotation to the base, and a drive pin is mounted to the rotator. The drive pin is advanced and retracted into engagement and out of engagement with the table. A rotator drive drives the rotator in reciprocating rotation, and includes opposed hydraulic drive and cushion cylinders mounted between the base and the rotator. The drive cylinder advances the rotator; the cushion cylinder cushions the advance, and returns the rotator to starting position. The drive and cushion cylinders are trunnion mounted to the base, for arcuate motion of the rods of the cylinders during rotary motion of the rotator. A control co-ordinates the advance and retraction of the drive pin and the drive and return of the rotator, for incremental forward advances of the press rotary table.
