Abstract

1,268,577. Boats' folding propellers. NAUTOR K.B. KOSKENKYLA & CO. 6 Oct., 1970, No. 47436/70. Heading B7V. A folding propeller has blades 2, 21 which are pivoted about a common pivot pin 3 and each carry a bevel gear 5 which meshes with the freely rotatable pinion 6 to ensure that both blades move equally between operative and trailing positions. In a modification the blades have spaced pivots and mesh directly with each other. The blades are thrown out by centrifugal force when the propeller shaft rotates and made to trail by water drag when the shaft stops.
