Bailey's Patent Steam Jack
1793

America's first steam turbine
This spit-turning device, or "jack," may well be the first steam turbine built and used in America. Used to turn a fireplace spit, it may also represent the earliest non-industrial application of steam power. The jack was placed near the fire, causing water in the spherical cast-iron boiler to turn into steam, which issued from the jet spinning the notched turbine "runner." This was geared down to the spit shaft on the jack's side. Today, steam turbines produce much of the electricity used in this country.
