ABSTRACT:
Apparatus for taking newly formed glass containers from a blow mold and transferring the containers to a dead plate wherein the take-out tongs for engaging the containers are mounted on a pair of holders that are pivoted like scissors relative to each other. A piston motor is pneumatically driven in one direction to cause the tongs and holders to close, and a spring, urging the piston in the opposite direction effects the opening of the tongs. When the tongs are open, the connection between the piston rod and the holders is a toggle linkage when the links are in a straight line preventing "winking" movement of the tongs toward closing by the fact of the toggle arrangement. Thus machine air closes the tongs and a fairly light spring force opens them.
