Abstract

4789. Douglas, J. March 7. Screw propellers.-In a feathering propeller, the sliding sleeve that controls the blades is arranged within a hollow bracket forming the. after bearing for the propeller shaft, and its operating-lever passes through' this bracket. The shank of each propeller blade has a flange g slotted to receive a block connected 'to the rod m by the pin l. These rods m pass through holes in the boss and in a sleeve on the propeller shaft, and are operated' by the sliding sleeve n arranged in the bracket. The motion of the blades when set for driving ahead is limited by screws (not shown), which bear agains the ends of the rods m. In modifications, the rods m may be formed as racks which engage -teeth formed on the peripheries of the flanges g, and the sleeve n, which may be fitted inboard, is moved longitudinally by rack-and-pinion gearing.
