Edison patent

In 1872, Thomas A. Edison was issued patents for an improvement in “Paper for Chemical Telegraphs” and for an improved “Apparatus for Perforating Paper for Telegraph Use” (U.S. Nos.132455, -6). The chemical paper Edison had previously designed used a solution of potassium iodide and starch adhered to paper and used while moist. He noted that when dry, the starch tended to crack and peel from paper. He patented an improvement using a very thin paste of flour and water that with the solution of potassium iodide would pentrate the paper fabric. In the second patent, Edison described a compact machine to punch perforated tape used to transmit telegraphic messages. Keys could punch either a single hole for a dot or three holes for a dash.
