Binding of a power-driven screw 10 is prevented by providing a driven nut 11 with a spherical end 12 which engages with a spherical seat 13 of the load-supporting member 14. The construction eliminates the high drag forces of the nut 11 and screw 10 due to loading of support member 14 at an offset position. The arrangement can be useful in paper- stacking devices attached to a high-speed line printer.
