ABSTRACT:
Internal gripper apparatus for use in uncasers and the like, for controllably gripping bottles or other containers from within for transport and release as desired. The internal grippers are spring-loaded to an outer position though automatically retract as required for insertion into the mouth of a container, gripping the container near the top, or at the ridge adjacent the top of the container characteristic of nearly all containers. The grippers have an upward extending centrally disposed actuating member which may be slidably encouraged to a lower position to retract the grippers and release a container held thereby. The grippers provide relatively close axial positioning of the containers to provide the desired separation of containers on container handling apparatus, and further include supporting structure to allow retraction of the gripper on engagement with broken or inverted containers or other obstructions in the normal operation of the gripper apparatus.
