Abstract

18,972. Sandberg, C. P. Aug. 22. Hardening.-The head only of a rail d which retains the heat existing therein after the completion of the rolling operation is cooled to a point below the critical temperature by directing thereon from a pipe a jets of a fluid, such as air or steam, or, according to the Provisional Specification, water, the rail being subsequently allowed to cool naturally. Specification 6658/05 is referred to.
