Abstract
A vertical positioner comprises a rigid frame. A rigid vertically extending structure extends upwardly from a base to its upper end portion. A generally horizontal flange forms the structure upper end portion. It has a central opening and at least two peripheral openings. A vertically movable structure is telescopically mounted to the frame. It comprises an upper plate located above the flange. A lower generally parallel plate is located below the flange. A pair of parallel rods extend between the plates and pass through flange bearings. A central tube is connected between the lower and upper plates and passes through the flange via bearings. A motor is supported rigidly relative to the base for motivating relative vertical motion.
