Abstract

367,265. Screw pumps. SULZER FR’RES SOC. ANON., Winterthur, Switzerland. June 4, 1931, No. 16190. Convention date, July 30, 1930. [Class 110 (i).] The impeller 2 of an axial flow pump has adjustable blades 3, each of which has a root 6 in the form of a circular disc held in a recess in the hub by a bolt 4 and nut 5. Sockets are provided in the hub and the blade root for the reception of locking pins. To secure the normal position of the blades 3, straight looking pins 9 are used as shown in Fig. 1, but by using pins 10, 11, with two displaced cylindrical parts as shown in Figs. 4, 5, the inclinations of the blades may be varied. The use of a set of pins having axes displaced to the same extent ensures all the blades having the same inclination.
