Note 100 — Chapter VIII · JAMES NASMYTH
Reading edition
Ibid., pp. 246-247. The self-acting valve motion for the steam hammer was invented by Mr. Wilson, when Nasmyth was absent on business. Wilson was manager at Patricroft and later became a partner. It was much used for a time but with the advent of balanced piston-valves the hand-operated gear supplanted it. Nasmyth’s invention of the hammer was denied by M. Schneider in 1871. For fuller discussion of the history of this hammer see London Engineer, May 16, 1890, and a pamphlet by T. S. Rowlandson, entitled “History of the Steam Hammer.” Manchester, 1866.
