Re: Petroleum Paper for Clothing Bales
It's a shame that the website did not offer annditional information such a patent numbers. I went back to the _Subject Matter Index_ and found one paper patent for Edison in 1872. He patented a method for making an improved paper for chemical telegraphs (no. 132455). Before Edison's patent telegraph paper had been made using iodide of potassium mixed with starch but only worked as long as the paper was kept damp. His method employed the use of flour and water mixed with the iodide. There was no mention of paraffine in his patent.
Additional patents were listed for Edison but they did not relate to paper.
