Partly-printed DS, signed “Dan’l Webster,” one page, 11 x 15, March 23, 1832. A patent issued to Daniel Rudd of Bozrah, Connecticut, for “Improvement in the mode of Propelling Ships and other Vessels.” The document reads, in part: “Be it known that I, Daniel Rudd…have invented a new and useful Improvement in Propelling Ships or other Vessels…From the sides of the vessel under the water-line I project four or more vertical shafts…on the lower ends of which are affixed cranks…that turn outside the vessel. Every other one; as first and third, are coupled together, so that when the first crank is turned to the right the third one will be moved in an opposite direction throughout this series. The second and fourth cranks have an operation independent of the first series, being geared together in the same way as those before described…What I claim as my invention, and desire to secure by Letters Patent, is—The continuous jointed scull moved by the cranks, &c., combined and arranged in the manner and for the purpose herein described.” Signed at the conclusion by Webster as secretary of state, and countersigned by Commissioner of Patents Henry L. Ellsworth. Green seal remains affixed to lower left corner. Attached to the patent by its original silk ribbon is a detailed schematic of the proposed improvement on a slightly larger onionskin sheet, as well as a handwritten description of the improvement, signed by Rudd on both sides. In very good to fine condition, with scattered light toning and soiling, and uniform toning to schematic.
