Description
Hardy and West's invention "consists in so arranging and constructing the several parts of a rotary steam-engine as to obtain a uniformity of wear throughout the machine. This we accomplish by placing within the exterior cylinder a cylinder eccentric to the exterior one, thereby leaving a crescent-shaped space for steam surrounding the periphery of the interior cylinder, which space is divded into four compartments by piston-blades, radial from the latter, and held against its flat surfaces..."
