Kiel assigned his rights to Kiel, Butler & Turnbull, of New York City, New York. His patent "consists in dissolving in benzine or other solvent any quantity of crude rubber. To this I add wood in a convenient form in any quantity up to ten times the original weight of the crude rubber. I then evaporate the solvent and obtain a mass which I mix with crude rubber, sulphur oil, and beeswax upon heated rollers. The compound thus obtained is ready for vulcanization." He thought that it could "be used to great advantage in the place of hard rubber, whalebone, ivory, and even wood..." (Patent Number 412,267)
