Abstract

1291202 Propellers CMI PRODUCTS Ltd 3 May 1971 12803/71 Heading B7V A ship's propeller has blades 28, 29 hinged about a pin 23 in a bush 10 which permits the blades to fold together when shaft 14 is stationary whilst allowing them to move radially (Figs. 4 and 5, not shown) on rotation of the shaft. A screw 30 engages groove 25 and so retains pin 23 in the boss. Shaft 14 is secured to the boss by a nut 19 which is locked against rotation by a screw 20.
