in the intense cold, and upon examining it the next morning found it as perfectly flexible as when he put it out. Goodyear had discovered the process which afterwards came to be known as “vulcanization.” The discovery was made in 1839, but was not accepted by those to whom it was submitted as possessing any importance. Prof. Silliman, of Yale College, however, in the fall of 1839 testified to the results claimed for it by Mr. Goodyear--that it did not melt with heat, nor stiffen with the cold. On June 15, 1844, Mr. Goodyear took out his celebrated patent, No. 3,633, covering this process, in which he not only used sulphur, but added a proportion of white lead. The proportions named were 25 parts of rubber, 5 parts of sulphur, and 7 parts of white lead, the ingredients either to be ground in spirits of turpentine, or to be incorporated dry between rolls. The odor imparted by the sulphur was to be destroyed by washing with potash or vinegar. This patent was reissued in two divisions Dec. 25, 1849, and again on Nov. 20, 1860, and was extended for seven years from June 15, 1858, which was the end of the first term. Under this patent two kinds of rubber were made and sold--“soft rubber,” containing only a small proportion of sulphur, while the other, known as the “vulcanite,” “ebonite,” or “hard rubber,” had from 25 to 35 per cent. of sulphur and was subjected to a longer heat. The history of this patent is a remarkable one. Immensely valuable as it was, Goodyear reaped but a small share of the profit, for in the midst of his poverty and necessities he was obliged to sell licenses and establish royalties at a figure far below the real value of the rights conveyed. Some idea of the great value of the business which Mr. Goodyear had developed may be had from the fact that the companies who held rights under the patent for the manufacture of shoes paid at one time to Daniel Webster the enormous fee of $25,000 for defending their patent interests.
