Abstract
A neck ring mechanism for transferring a blank or parison from a blank mold section to a blow mold section of an I.S. glass forming machine includes a rock shaft and a pair of spaced cylinders reciprocable in opposition directions on the shaft. The rock shaft is provided with a plurality of longitudinal grooves, and a like plurality of followers are arranged in the grooves so as to contact at least one side wall of each groove. The followers are supported on each cylinder. One or more piston rings are seated in associated annular grooves in the rock shaft so as to preclude air leakage.
