Abstract
372,139. Turbine blades. FAIRWEATHER, H. G. C., 65, Chancery Lane, London.-(Allmanna Svenska Elektriska Aktiebolaget; Võsteras, Sweden.) June 22, 1931, No. 18096. [Class 110 (iii).] Turbine blades of the type having a laterally projecting root at each end are manufactured by first subjecting the blank, Fig. 1, to one or more pressing operations which form the roots 2, 2, give the surface 3 of the blade between the roots its finished form, and press the opposite surface 4 of the blade to plane shape, the remaining surfaces being rough pressed as shown in Fig. 2. The blade is hardened and cleaned and the burs removed. The surface 4 is then milled to the desired shape and its edges 5, 6 milled to straight form, as in Fig. 4. The surfaces 7, 8 of the roots and the end surface 9 of one root, Fig. 6, are then milled to plane shape. The upper surfaces 10 of the roots are then milled to a shape corresponding to that of the surface 4, the finished blade being shown in Fig. 8.
