Patent Number	Date	Title	Name	City	Description
X3,131	Sep. 06, 1819	Machine for turning gun stocks	Thomas Blanchard	Millbury, MA	This patent was withdrawn and reissued 1820-01-20, "by act of Congress."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. From the 1886 book, "Federal Decisions, Vol. XXV. Patents, Copyright and Trade-marks", this patent was involved in the following litigation. "Construed not to include the power for working the combination; the claims sustained, Blanchard Gun-stock Turning Co. v. Warner, 1 Blatch., 278. Reviewed, Blanchard v. Beers, 2 Blatch., 413. Construed, and renewal by congress void for error as to description and date in act of congress. Blanchard v. Sprague, 3 Sumn., 279. Construed; held not unconstitutional; infringed, Blanchard v. Sprague, 3 Sumn., 535. See, also, Blanchard v. Whitney, 3 Blatch., 307; v. Sprague, 2 Story, 164; v. Eldridge, 1 Wall. Jr., 337; Blanchard Gun-stock Turning Co. v. Jacobs, 2 Blatch., 69." The above book also has the following information under the date of the patent issued 1820-01-20, which is the date of the act-of-Congress reissue. "Construed and held infringed, Blanchard v. Reeves, 1 Fish., 103. See, also, Blanchard v. Sprague, 3 Sumn., 535; 3 Sumn., 279; 2 Story, 164; v. Eldridge, 1 Wall. Jr., 337; v. Sprague, 1 Cliff., 288; v. Haynes, 6 West. L. J., 82; v. Beers, 2 Blatch., 413; Blanchard Gun-stock Turning Co. v. Jacobs, 2 Blatch., 69; Blanchard Gun-stock Turning Co. v. Warner, 1 Blatch., 278."
X4,300	Dec. 28, 1825	Regulating the speed of carriages	Thomas Blanchard	Springfield, MA
X8,347	Aug. 08, 1834	Circular sawmill	Thomas Blanchard	New York, NY	"...a description in the words of the said Thomas Blanchard himself of his improvement in the saw mill, which he calls Blanchard's shifting circular saw mill." The log carriage moves longitudinally back and forth and does not move transversely, i.e., side to side. The blade and arbor are mounted in a frame that can be moved transversely so as to adjust the thickness of the board to be sawn. Although this idea turned out to be an evolutionary dead end, it was a clever way to simplify the design of the saw by decoupling the longitudinal and transverse adjustment movement mechanisms.

The judge and jury ruled that Blanchard's patent covered a combination of parts composing a wood-bending machine, that Morris' patent design does not infringe on Blanchard's design, and therefore the verdict was for the defendants.
