Neck ring apparatus is disclosed for retaining and conveying glass along a predetermined path as the glass is transformed from an initially formed parison to a final blown glass article having a desired finish. A pair of sprockets, forming a part of the neck ring mechanism, selectively engage roller tracks as the mechanism proceeds along its predetermined path to (1) open segments of the neck ring so as to permit the delivery of a charge of molten glass to a mold position therebelow, (2) to close the neck ring segments so as to form a finish on an initially formed parison and retain such parison by said finish, (3) rotate the neck ring and accordingly said parison for uniformly cooling the parison and for removing blow mold seams during the blowing of the final article, and (4) to open the neck ring segments to remove the finished article therefrom.
A neck ring mechanism for transporting, rotating and releasing a glass article which comprises, a neck ring housing, a neck ring rotatably mounted within said housing and comprising a plurality of neck ring segments, an inner bearing ring mounted for rotation within said housing, means slidably mounted with respect to said inner bearing ring and operatively retaining said neck ring segments for opening and closing the segments of said neck ring, rotatable cam means for actuating said slidably mounted means, and means for rotating said cam means and camming said slidably mounted means inwardly for closing said neck ring segments and for rotating said neck ring.
A neck ring mechanism which is both rotatable for rotating a glass article retained thereby and slidably openable for releasing such article which comprises, a housing, a plurality of yoke means mounted within said housing for sliding movement toward and away from each other, a plurality of neck ring segments each operatively connected to one of said yoke means, cam means for selectively sliding said yoke means toward and away from each other for closing and opening said neck ring segments and for rotating said neck ring segments when they are in a closed position, and means for rotating said cam means for effecting the closing, rotation and opening of said neck ring segments.
A neck ring mechanism having a segmented neck ring which is not only slidably closable and openable for retaining and releasing a glass article but which is also rotatable for rotating the retained article which comprises, a housing, means for moving said housing along a predetermined path, a cam plate mounted for rotation within said housing, an inner bearing ring mounted for both relative rotational movement with respect to said cam plate and for unitary rotation therewith, a pair of opposed yoke members slidably mounted within said inner bearing ring toward and away from each other, a pair of neck ring segments each being operatively attached to one of said yoke members so as to form a split neck ring which is openable and closable upon the sliding movement of said yoke members, said yoke members being mounted for unitary rotation with said inner bearing ring, stops means for limiting the relative rotation between said cam plate and said inner bearing ring, ring gear means attached to said cam plate for unitary rotation therewith, gear means for rotating said ring gear and said cam plate in clockwise and counterclockwise direction, cam surface means forming a part of said cam plate, pin means secured to each of said yoke members and operatively engagable with said cam surface means;
