ABSTRACT:
Chuck for a bottle capper. In previously known chucks for bottle cappers, especially those made in accordance with U.S. Pat. No. 3,537,231 and its immediate predecessors, there has been a tendency during operation for the chuck jaws to twist or cock which is damaging to the bottle caps. The present invention provides a ball inserted between a portion of the chuck jaw and the walls surrounding and encasing same, which ball positively resists such twisting or cocking without interfering with the desired opening and closing of the jaws. Further means are also provided for improving the smoothness of operation of the apparatus, namely a roller over the drive pin by which rotation of the jaws is effected.
