The open section of the case at the top was covered with a screw-fastened thin sheet of cold-rolled steel.
The modulus of ultimate resilience of the cold-rolled iron is, however, above 50 per cent.
Piston-rods of cold-rolled iron, fitted and keyed to pistons and crossheads.
The pins are made of cold-rolled shafting, and fit to a nicety.
A 1/8-inch cold-rolled steel driving or propeller-shaft is used.
They were all cut from the same strip of metal, but some were "cold-rolled," some "annealed," and some "hardened."
From this it appears that cold-rolled iron is peculiarly adapted for line shafting.
