Hill assigned one-half his right to Patrick York of St. Louis, Missouri. His patent "consists in supporting the paddle-wheel of a stern-wheel steamer on a frame, the opposite end of which carries the cylinders of the steam-engine, and this frame is supported on pivots intermediately of its length, so as to be as nearly balanced thereon as possible, whereby the dip of the wheel may be adjusted with ease, and its full diameter made available at any draft of water to which the vessel may be loaded."
