ABSTRACT:
Apparatus for opening and closing mold arms in a glassware forming machine includes a gearbox for mounting on a glassware machine frame, a cylinder housing suspended beneath the gearbox, and a mold open/close cylinder disposed within the cylinder housing. The cylinder has a mold open/close piston with an extending piston rod and a gear rack machined or otherwise formed in the piston rod. A first drive gear in the cylinder housing is coupled to the gear rack and a drive shaft extends from the first drive gear and the cylinder housing into the gearbox. A second drive gear is disposed in the gearbox and coupled to the drive shaft. Laterally spaced operating shafts extend upwardly from within the gearbox. Means including an idler gear couple the second drive gear to the operating shafts such that the operating shafts are rotated simultaneously in opposite directions by the cylinder, the gear rack, the first and second drive gears and the idler gear. In exemplary embodiments of the disclosure, the means include driven gears or connecting links coupling the second drive gear and the idler gear to the operating shafts. Linkages couple the operating shafts to the mold arms of the glassware forming machine.
