Abstract

315,211. Soc. Rateau. July 9, 1928, [Convention date]. Addition to 309,181. Blades. - In steam turbine wheels in which, as in the parent Specification, outer blades i, i<1> are superposed upon inner blades a, the blades i are formed integral with the blades a of the inner ring, and the alternate blades i<1> have roots c<1> which interlock with intermediate parts b of the double blades a, i. The roots c' may be hollowed out.
