Adams, John Quincy (1767-1848) Letters Patent Signed, Washington, D. C., 9 October 1828. Five parchment leaves bound together with pink silk thread; the first leaf engraved and printed by W.I. Stone of Washington, D.C.; bearing the seal of the United States over pink ribbon, and fulfilled by hand; signed by John Quincy Adams as President, Henry Clay as Secretary of State, and William Wirt as Attorney General; one added leaf containing an original drawing of the invention. The patent acknowledges Rufus Tyler's invention of a machine that allows a revolving engraving or etching point to engrave circular lines onto a printing cylinder, thereby transferring the pattern to other printing cylinders for printing calico fabric, bank notes, and other purposes; thumbing, the drawing with a clean tear down the center, the document slightly curled, with the original tin storage tube, 15 x 11 1/2 in. Rufus Tyler was a talented Philadelphia machinist who made many fine turning lathes, rose engines, slide rests, and other machines for straight line and circular line engraving, including this invention for engraving bank note dies and milling cylinders for printing calico.
