. Bulletin - United States National Museum. Science. Figure 24.—Wilson's prepatent model for his rotary hook, 1851. (Smithsonian photo 45506-E.) claimed control of the double-pointed shuttle. Al- though this claim was without justification, as can be seen by examining the Bradshaw patent specifica- tions, Wilson did not have sufficient funds to fight the claim. In order to avoid a suit, he relinquished to A. P. Kline and Edward Lee, a one-half interest in his U.S. patent 7, 776 which was issued on November 12, 1850 (fig. 23). Inventor Wilson had been associated with Kline and Lee (E. Lee & Co.) for only a few months, when, on November 25, 1850, he agreed to sell his remaining interest to his partners for $2, 000. He retained only limited rights for New Jersey and for Massachusetts. The sale was fruitless for the inventor, as no payment was ever made. How much money E. E. Lee & Co. realized from the Wilson machine is difficult to determine, but they ran numerous ads in the 1851 and 1852 issues of Scientific American. A typical one reads: A. B. Wilson's Sewing Machine, justly allowed to be the cheapest and best now in use, patented November 12, 1850; can be seen on exhibition at 195 and 197 Broadway (formerly the Franklin House, Room 23, third floor) or to E. E. Lee & Co., Earle's Hotel. Rights for territory or machines can be had by applying to George R. Chittenden, Agent.48. Figure 25.—Wilson's rotarv-hook patent model, 1851.

Wilson's Sewing Machine . . the best and only practical sewing machine—not larger than a lady's work box—for the trifling sum of $35.49 Wilson severed relations with Lee and Kline in early 1851 shortly after meeting Nathaniel Wheeler, who was to become his partner in a happier, more « Scientific American'Dec. 6, 1851 ), vol. 7, no. 12, p. 95.
