Photo embossingIn 1895, black American inventor, Clatonia Joaquin Dorticus of Newton, New Jersey, patented a "machine for embossing photographs" (No. 537,442). Photographic prints could either be mounted, or embossed by using proper dies. A bed plate carried the female die. An upper hinged plate held the male die. They were closed and pressed together with a lever bar. The device was designed to distribute equal pressure over the entire surface of the photographic film. A few days later, he also patented a photographic print wash. One month before, he was issued a patent for "a device for applying coloring liquids to sides of soles and heels of shoes." In 1899, Dorticus received a patent for his invention of a "Hose Leak Stop."« |
