Vintage Machinery entry for John W. Cochran

|
Description: |
| Very complicated, massive machine that is intended for cutting ship parts. It can rotate the log as it is being cut, so as to produce compound-curved pieces. The patent is exceptionally long for such an early patent: 14 pages.The 30 September 1848 issue of Scientific American carried an article about a British trial, Hamilton versus Cochran. It seems that James Hamilton (patent 3,053) 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. |
