Abstract

A glass container forming machine section (10) in which the mold carrying arms (12, 14) that are pivoted on shafts (20, 22), respectively, about a common axis (A) are caused to counteroscillate between open positions in which the mold halves (16, 18) that are respectively carried by the arms (12, 14) are separated, and closed positions in which the mold halves are joined to define molding cavities therebetween. The opening and closing motions of the mold carrying arms are powered by a single reversible electrical servo motor (24), which drives a drive gear (26). The drive gear (26) directly drives a first driven gear (28) and an intermediate driven gear (30) which, in turn, directly drives a second driven gear (34). Turning motion of the driven gears (28, 34) is imparted to stub shafts (38, 40), respectively, which carry coaxial drive gears (42, 44), respectively. The drive gears (42, 44) drive sector gears (46, 48), respectively, that are disengagably secured to the shafts (22, 20), respectively. The servo motor (24) has dual windings; a first, higher speed/lower torque winding for operating the motion of the mold carrying arms during a first portion of their closing movements and…
