ABSTRACT:
Apparatus at the operator's side of a rolling mill is used to move the chock for one of a pair of rolls in an axial direction thereof for alignment between roll pass openings in the bodies of the pair of rolls. The apparatus includes a chock extension sleeve having an externally-threaded surface and a flange at one end attached by bolts to the roll chock at the operator's side. Two nut members are jammed together under sufficient torque for a stressed engagement with the threaded surface of the sleeve. The nut members are joined together by a threaded bolt for simultaneous rotation of the nut members. Gear teeth are formed on an outer annular section of one of the nut members to mesh with a pinion gear rotatably supported by a clevis forming part of the keeper blocks supported by the mill housing. The outwardly-projecting section forming the gear teeth is engaged by support surfaces in the forked end of the clevis to retain the nut members and cause upon rotation thereof displacement of the chock extension sleeve as well as the chock in a direction which is parallel to the rotational axis of the roll.
