The Hulett automatic ore unloaer was invented by George Hulett of Ohio in the late 1800s; he received a patent for his invention in 1898. The first working machine was built the following year at Conneaut Harbor in Conneaut, Ohio. It was successful, and many more were built along the Great Lakes, especially the southern shore of Lake Erie to unload boats full of taconite from the iron mines near Lake Superior. Substantial improvements were later made on the design by Samuel T. Wellman. It is these second-generation Huletts which continue to stand to this day.
