Corliss steam engine valve overview

By the 1840's, Providence RI was the epicenter of steam engine manufacturing and development. From this flurry of activity came the most significant improvement since those of James Watt. In 1849 George Corliss of Providence patented the first version of his revolutionary valve gear. His technology went on to be licensed and adopted by steam engine manufacturers around the world as it more than doubled the efficiency of any previous designs. Here we take a brief overview of some of the details of what made it different from its predecessors. Soon we will have another video with a bit more technical information on this incredible leap forward.
