elliptical-shaped cylinder, and also in the peculiar arrangement of a central circular valve which proceeds into the bore of the piston and communicating with ports formed radially in the piston for the admission and exit of steam to and from each of the driving-blades of the piston. The invention further essentially consists in the means for independently or concurrently operating the valves, and also in means for controlling the elliptical travel of the multiple blades and for the simultaneous admission and exit of steam to and from opposite points of the piston, so allowing of an easy and instant reversal of the engine and also of the use of the steam to its maximum expansive value.
