Abstract

1,239,178. Fairleads. Y. MASUDA and H. FUKADA. 18 April, 1970, No. 18619/70. Heading B8B. [Also in Division E1] Twisting of a flexible member 20 as it passes over pulleys 6 and 10 at the ends of a ship is prevented by rotatably mounting each pulley on an associated shaft 32 so chordwise secured in a ring rotatably mounted in support means rigidly secured on the ship. With such an arrangement the member will always pass about the pulley at the centre of the ring in a plane at right angles to the axis of rotation of the pulley.
