===== Comments =====

This patent was withdrawn and reissued 1820-01-20, "by act of Congress." It is one of the most important woodworking-relating patents, and was a key innovation in the industrial revolution. It was extended by act of Congress on 1834-01-20 and again on 1848-01-20.
James L. Haven & Co. is listed as a manufacturer: "Blanchard's Patent Lathes for turning irregular forms" was listed as a product they made in an 1854 directory ad. Undoubtedly there were numerous other licensees of Blanchard's patent but as yet we have not identified any others. A search of old court records would likely turn up several names.
