ABSTRACT:
A neck ring arm assembly for a glass container forming machine of the individual section type comprising a horizontally extending invert shaft and a vertically extending cylinder with a rack that engages a spur gear attached to the invert shaft to oscillate the invert shaft. The invert shaft has an inner annular sleeve keyed to it, and the inner annular sleeve has a polygonal exterior, preferably a hexagonal exterior. First and second outer annular sleeves surround the inner annular sleeve to be oscillatable therewith, but reciprocable with respect thereto. Each of the first and second outer annular sleeves has a polygonal interior which is complementary to the polygonal exterior of the inner annular sleeve, and each is provided with a plurality of replaceable wear pads each of which is adjustable toward a surface of the polygonal exterior of the inner annular sleeve to provide for close, low backlash engagement of the inner annular sleeve by the outer annular sleeves over a prolonged duration. A neck ring carrying arm, made up of a pair of neck ring arm elements each of which is secured to one of the outer annular sleeves, is provided to carry the neck rings and container parisons as the neck ring arm assembly is moved from the blank mold of an I.S. machine to the blow mold side by the motion of the invert shaft in a first arcuate direction, and to carry the neck rings back to the blank mold side after releasing the parisons to blow molds at the blow mold side by arcuate motion in an opposed arcuate direction.
