Abstract
202,288. Soc. Rateau. Aug. 11, 1922, [Convention date]. Blades; balancing moving parts. - To reduce centrifugal strain and to facilitate balancing, turbine rotor blades are provided with cavities which are bored or milled cut, without changing the general shape of the blade. The sectional area of the cavity preferably diminishes towards the rotor shaft. The blade 1, Figs. 1 and 2, may be pieced longitudinally by a conical central hole 2, and by two smaller holes 3. A stepped hole may be provided, or a single tapering hole. The blade may be milled-cut at the back, Fig. 8, or at the side, Fig. 11, to prevent eddies. To balance the rotor, certain blades may be hollowed more than others. The Specification, as open to inspection under Sect. 91 (3) (a), comprises also a blade made in two parts 5, 6, Fig. 13 (Cancelled). By swaging and welding a tube or other member, the blade shown in Fig. 17 (Cancelled), may be formed. This subject-matter does not appear in the Specification as accepted.
