ABSTRACT:
A device for moving objects about the inside of a closed container includes a grasping mechanism for grasping and releasing objects and an operating mechanism for operating the grasping mechanism and for moving the grasping mechanism about the inside of the container. The operating mechanism includes a pair of arm bodies each of which slidably move through a wall in the container along a linear pathway. As a result of the linear movement of the arm bodies, close tolerance seals can be used to seal the opening sufficiently to allow sliding movement without significantly disturbing the atomspheric and temperature conditions in the container. At least one of the arm bodies is composed of a pair of arm body portions, each portion having a surface slidable with respect to the other portion. The outer ends of the arm bodies positioned outside of the container are suitably coupled to a driver for moving the arm bodies along a linear pathway. The inner ends of the arm bodies are pivotally coupled by a suitable connection to the grasping mechanism. Selective linear movement of the arm bodies, and arm body portions with respect to each other, enables the grasping mechanism to operate and move about the inside of the container in a multiplicity of directions.
