US patent specification and drawing sheet for Frederick Juncker of Paris, granted February 22, 1887 (filed June 10, 1886). It describes making lace, galloon, and guipure by embroidering by hand or machine on a sheet of gutta-percha or india-rubber, then dissolving the backing in benzine or carbon sulphide to leave an open-work embroidered fabric. The patent contrasts this with older paper or fabric foundations removed by acid or heat, which damaged the threads. The claim covers lace or open-work fabric secured on a soluble gum, india-rubber, or gutta-percha ground.
