US Patent No. 53,991, granted April 17, 1866 to Charles Lang of New York, for a machine that turns plain paper into lace-paper. A foot-operated press embosses the paper between dies. A rotating, vibrating drum covered with ground glass or emery then grinds off the raised parts, and a sucking-blower removes the dust. The scan has three sheets of patent drawings (Figs. 1-5) and a two-page specification with three claims. The specification refers back to Lang's earlier patent No. 46,115 of January 31, 1865.
