A finger chuck assembly and method for holding a bottle or other hollow article having a neck opening at one end, characterized by a support member having an axis; a plurality of jaws each including a finger, an actuator arm and an intermediate portion interconnecting the finger and actuator arm; and a chuck operator member carried on the support member for movement relative to the support member. The jaws each are pivotally mounted at the intermediate portion to the support member for movement of the jaw between a contracted position for inserting the fingers into a neck opening of a hollow article and an expanded position for engaging an interior surface of the hollow article. The fingers of the jaws extend generally parallel to one another and to the axis of the support member when the jaws are in the contracted positions thereof and diverge laterally outwardly away from one another when the jaws are in the expanded positions thereof. The chuck operator operatively engages the actuator arms of the jaws for effecting movement of the jaws between the expanded and contracted positions in response to movement of the chuck operator relative to the support member. Other forms of chucks are also disclosed.

A finger chuck assembly for holding a hollow article having a neck opening at one end, comprising a support member having an axis; a plurality of jaws each including a gripping finger, an actuator arm and an intermediate portion interconnecting the gripping finger and actuator arm, the jaws each being mounted at the intermediate portion to the support member for pivotal movement of the gripping finger thereof between a contracted position for insertion into a neck opening of a hollow article and an expanded position for engagement with an interior surface of the hollow article, the gripping fingers of the jaws extending generally parallel to one another and to the axis of the support member when in their contracted positions and diverging laterally outwardly away from one another when in their expanded positions; and a chuck operator member carried on the support member for movement relative to the support member, the chuck operator member operatively engaging the actuator arms of the jaws for effecting movement of the jaws and corresponding movement of the gripping fingers between their expanded and contracted positions in response to movement of the chuck operator member relative to the support member, and wherein each jaw has associated therewith a respective resilient element which operates to bias the gripping finger toward its expanded position.
