Abstract
A support and actuating mechanism (30) includes an actuator (244) mounted adjacent a vertical post (242) of a framework (236) and also includes a plurality of connectors (246) extending from the actuator to a mold support assembly (28) located within a heated chamber (22) of a housing (20) to perform forming of heated glass sheets. Each connector (246) includes a vertical connector rod (248) that extends upwardly from the actuator, an upper pivot link (254) connected to the vertical connector rod (248) and to a horizontal connector rod (258), a sector wheel (264) connected to the horizontal connector rod (258), and a flexible member (268) that extends from the sector wheel (264) to a mold support rod (270) that supports the mold support assembly (28) to provide vertical movement thereof under the operation of the actuator. The sector wheels (264) are preferably constructed as sprockets and the flexible members (268) are chains received by the sprockets. The actuator (244) includes a counterbalance (272) that includes a gas cylinder (274) and a pressurized gas reservoir (280).
