"Vintage Machinery" entry for James Hamilton
Description:
Sawmill makes curved cuts by rolling the log during while being sawn.

The 30 September 1848 issue of Scientific American carried an article about a British trial, Hamilton versus Cochran. It seems that James Hamilton sued John W. Cochran in Britain regarding patent infringement for this design: both inventors had secured British patents also. Judgement was in favor of Mr. Hamilton. For Cochran's design, see American patent 5,394.
