Abstract
A manipulator for movement of articles in a controlled environment chamber, specially a high vacuum chamber, in which a bellows has one end sealingly connected to a wall of the chamber and has a cover sealingly connected to the other end with a closed sleeve in the cover and also sealingly connected to the other end of the bellows. A ball is located in about the center of the bellows and a ball cup supporting the ball is fixed to the wall of the chamber. The connection of the ball cup and the bellows to the chamber wall is advantageously by means of a flange. A manipulator rod is slidable in the ball and one of the ball and rod is rotatable. Magnetic means on the manipulator rod in the sleeve is coupled to magnet means outside the sleeve and by manipulation of the magnet means the rod can be reciprocated and rotated. The cover is provided with extensible supports connected between the cover and the flange for tilting the cover together with the sleeve and manipulator rod on the flange. Electric motors are preferably provided for actuating the extensible supports and for reciprocating the magnet in the housing and for rotating the magnet in the housing.
