PROCESS FOR PRODUCING TAPERED IRON.

In No. 430 of this Journal, page 207, there is some mention of the patented rolling process for tapering bar-iron by machinery. This important invention is not of American origin, as persons unacquainted with the facts might imagine: it was first practised at the Mersey Steel and Iron Company's works at Liverpool, and then patented by Mr William Clay in the United States. The Company mentioned were awarded for the manufacture the prize-medal of the Great Exhibition, and the silver medals of the Franklin Institute of Philadelphia, and the American Institute of New York.
