Abstract: Mill roll changing apparatus for positioning transversely of a rolling mill pass line and arranged for receiving and inserting mill rolls relative to a juxtaposed mill stand comprises a movable floor section normally covering a roll changing pit adjacent the mill stand, a support structure for the floor section and positionable within the pit, and a number of rails on the floor section. Driving mechanism is provided for moving the floor section laterally of the support structure in a direction generally parallel to the mill pass line so that selected pairs of the floor section rails can be laterally aligned with a pair of rails within the mill stand. An elevating mechanism mountable within the pit is structured for elevating the floor section to a first position above an existing floor surrounding the pit so that the floor section can be moved laterally thereof and to a second position whereat the floor section is flush with the existing floor and to a third position whereat the floor section is recessed within the roll-changing pit.

Abstract: An entry guide mechanism comprises upper and lower platens positioned to receive an elongated workpiece therebetween. A pivotably mounted support is secured to the upper platen for pivotally supporting the upper platen, and a pivotally mounted support is secured to the lower platen for pivotally mounting the lower platen. An angularly displacing drive mechanism is secured to at least one of the pivoted supports to pivot portions of the platens toward one another to clamp the workpiece therebetween. The pivotal mountings for the platens conform the attitudes thereof with that of an adjacent segment of the workpiece.

Abstract: A thrust mechanism on a shaft structure comprises a member slidably mounted on the structure for movement longitudinally thereof, stop means positioned on the structure at the terminus of such movement, and first and second thrust members. The first thrust member is slidably mounted on the structure for movement longitudinally thereof into bearing contact with the slidable member. Means are provided for slidably mounting the first thrust member against turning movement thereof relative to the structure. Second stop means are provided on the shaft structure, together with means for mounting the second thrust member against the second stop means for turning movement thereof relative to the shaft structure. Means are provided for securing the second thrust member to the structure against further turning movement thereof following a predetermined limited angular displacement of the second thrust member, together with means on at least one of the thrust members and engageable with the other of the thrust members for urging the first thrust member and the slidable member against the first stop means and for urging the second thrust member against the second stop means.
