A beam mill stand has lower horizontal roll chocks (16), supported by a screw-up (17) while upper horizontal roll chocks (14) suspended on hooks (26) from balance beams (25) are urged downward by screw-downs (15). Vertical roll chocks (22, 24) are supported by and moveable in transverse guide ways. In order to facilitate changing of the rolls as an interlocked stack, there are resilient support mechanisms (49-58) in the upper horizontal roll chocks which are restrained by the hooks (26) on the balance beams (25) with the mill in use and when the beams are lowered resilient support mechanism are released and extending engage the vertical roll chocks thus supporting the upper horizontal roll chocks resiliently. An interlocking mechanism (36-48) in the vertical rolls is operated by the resilient support mechanism (49-58) so that the vertical and lower horizontal roll chocks are locked against lateral movement. |
