ABSTRACT:
A fixture for removing locking tubes from locking positions in a top nozzle includes a tool guide and a tool holder mounted above the tool guide for movement toward and away from the guide. Further, the fixture includes locking member removal tools each in the form of an outer elongated tubular member and an inner elongated actuating shaft. The tubular member is attached to the tool guide in alignment with one of its openings, while the actuating shaft is mounted to the tool holder and extends through the tubular member. When the tool guide is disposed on the top nozzle, both the tubular member and actuating shaft of each removal tool extend downwardly through one locking tube. The lower portion of the tubular member is in the form of a segmented sleeve having a lower segmented rim which is movable between circumferentially-collapsed and expanded positions. The actuating shaft of each tool has an upper cylindrical portion with an outside diameter larger than the inside diameter of the locking tube. Consequently, insertion of the upper shaft portion into the lower segmented sleeve of the tubular member upon predetermined movement of the tool holder relative to the tool guide causes the sleeve rim of each removal tool tubular member to assume its expanded position in which it engages the lower end of one of the locking tubes. Then, withdrawal of the tool guide and tool holder results in removal of the locking tubes therefrom also.
