Together with: Some Account of Nathaniel Hayward's Experiments with India Rubber, which Resulted in Discovering the Invaluable Compound of that Article with Sulpher. Norwich, Conn.: Bulletin Job Office, Franklin Square, 1865, pp. 12; original printed tan wrappers; fine. Nathaniel Hayward (1808-1865), a man without any training at all in chemistry, spent some years experimenting with ways to keep India rubber from becoming soft and sticky in summer. He first discovered the value of sulfur in rubber compounding in 1836. Continuing his experiments he subjected his sulfur-treated rubber to the heat of the sun's rays, particularly anticipating the process of vulcanization. In 1838 he met Charles Goodyear, and eventually assigned the rights to his new process to him, and later assisted Goodyear in his experiments on vulcanization. In his petition to Congress, Hayward argues that the renewal of the patent for the process of combining sulfur with India rubber should be assigned to him, and not to Charles Goodyear. He explains that although he assigned the rights of the first patent to Goodyear in 1839, he did so only for a period of 14 years, and that the Patent Office has illegally denied him an extension of the patent on his own product.
