Manipulator usable for a glass electrode or the like

Claim 1

A manipulator assembly for moving a glass electrode or the like in a lateral, a longitudinal and a heightwise direction, comprising: means for providing a rough adjustment of the position of the glass electrode in the lateral, longitudinal and heightwise direction; a first base member which is adjustable in the heightwise direction by said rough adjustment means, said first base member having a small spherical body projectively provided thereon; means for providing fine adjustment of the position of the glass electrode in the longitudinal and lateral direction; including a large spherical body having a receiving bore defined therein, a sleeve adapted to be operably connected to the glass electrode for housing the large spherical body, a first fine movement slider means for allowing the sleeve to move relative to the first base member in the lateral direction, and operation lever means for rotating the large spherical member relative to the sleeve, the small spherical body being receivable in said receiving bore, whereby movement of the operation lever means causes the glass electrode to finely move in the lateral and longitudinal direction; a hydraulic cylinder disposed in said operation lever means having a diaphragm therein and operation knob mounted thereon for actuating said diaphragm; and hydraulic means for providing fine adjustment at the position of the glass electrode in the heightwise direction, said hydraulic means being actuatable by fluid supplied from said hydraulic cylinder, whereby a glass electrode may be positioned by being moved to an approximate desired position by said rough adjustment means, and to a final position by using said fine adjustment means and said hydraulic means.
