Apparatus for applying thermoplastic coating to glass containers includes a plurality of chuck bars, from each of which a plurality of container holding chucks are suspended, each of the chucks consisting of a U-shaped member upon which a lip or projection on the container neck is supported and from which the container is suspended and a loosely fitting cap member which drops over the top of the container. The chuck bars are supported by end members adapted to be transferred along a transfer track, preferably including rollers to facilitate such transfer. Movable transfer track segments are provided, to transfer chuck bars at specific positions for container pick-up and container coating. To effect longitudinal transfer of the chuck bars, elongated pusher members are disposed parallel to the transfer tracks. The pusher members includes dogs for engaging and disengaging the end members of the plurality of chuck bars. Means are included for transferring chuck bars in separate sections of the apparatus different transfer distances to provide for different spacing between transfer stations.
Bottle holding chuck including
Apparatus, as recited in claim 26, wherein said chuck engaging means includes means for moving said crank arms transversely to effect said chuck bar movement.
In a transport mechanism for articles to be conveyed through one or more pluralities of evenly spaced linearly disposed stations, wherein said articles are retained in a holder having end members adapted to be supported on a pair of transfer tracks running lengthwise along said stations and to be moved along the length thereof, the improvement consisting of a pair of elongated pusher members disposed parallel to said transfer tracks with end member engagement pusher dogs, adapted to engage said end members, at spaced positions along the length of said pusher members corresponding to the positions of said stations, said dogs extending toward the space between said tracks, locking-unlocking means adapted to rotate said elongated pusher members in opposite directions to cause said dogs to engage and disengage said end members, and longitudinal transfer means for moving said pusher members lengthwise, from the starting position thereof, in the direction said articles are intended to be transferred, while said dogs are in the engaged position thereof, and for returning said pusher members from their end transfer position to their starting position while said dogs are in the disengaged position thereof.
