Abstract

26,090. MacLaren, A. P., MacLaren, F. L., and MacLaren, A. M. Nov. 11. Screw propellers.-The blades of folding propellers are actuated by means of a slotted block C engaging crank-pins fitted to the blade shanks and provided with loose bearing-blocks a9, b<6>. Movement of the block C is effected by a rod D. The boss is split, the parts a, b being secured together by nuts a<2>, b<3>. The blades are mounted at rightangles to the axis of the shanks, as shown.
