An invert assembly for an individual section glassware forming machine includes an invert base that is oscillated about an axis between angularly spaced apart first and second positions, a double ended ball screw positioned co-axially with the axis and having spaced apart oppositely threaded portions, first and second nuts each threadably engaging one of the oppositely threaded portions of the ball screw so that the nuts reciprocate toward and away from each other in response to rotation of the ball screw, and first and second neck ring arms respectively engaging the first and second nuts so that the neck ring arms reciprocate toward and away from each other along the axis with the first and second nuts. Preferably, the invert base is oscillated about the axis by a first reversible electric motor, and the ball screw is driven for rotation in opposed directions by a second reversible electric motor to move the nuts and neck ring arms toward and away from each other along the axis.

Invert arm assembly for glassware forming machine

A takeout device ( ) for transferring one or more, usually a plurality, of freshly-formed glass containers (C) from molds ( ) of a section of an I.S. machine to a deadplate ( ) of the machine. The takeout device has an oscillatable arm ( ) that carries a head ( ) from which a tong ( ) for each of the containers is suspended. Oscillation of the arm is powered by a reversible, linearly-acting electrical motor ( ), preferably an a.c. servo motor, that causes a rack ( ) to reciprocate. The rack drives an oscillatable gear ( ) that oscillatingly drives the arm. The motor is mounted at the top of a post ( ) at an elevation above the elevations of the molds and the deadplate, and the motor, therefore, is readily accessible for maintenance and adjustment.
