Description: |
Improvements to Elbridge G. Hastings' patent 10,636. Charles T. Porter was a lawyer who was hired by Hastings, and Hastings ended up giving Porter a half-interest in patent 10,636 as payment for services. Porter, who had no prior training or experience as a mechanic, realized that Hastings' design had some good ideas but was not yet practical. Porter learned mechanics and technical drawing on the fly and then made improvements to Hastings' design; this patent is the result. Porter discovered that their stone-dressing machine was producing a rippled surface due to the poor speed regulation of the steam engine driving the machine; Porter went on to design a new steam-engine governor, patent 20,894. Porter would become the most important designer in the emerging field of high-speed steam engines. |
