Apparatus for adjusting and locking the pitch of a variable pitch propeller. Within a propeller shaft, a hydraulic piston is provided which drives a rod, a plate, and levers to rotate the propeller blades in, and with respect to, the hub of the propeller. The root of the propeller within the hub has a conical portion which has a mating conical ring thereabout. This conical ring is engaged and locked into place with the conical portion of the propeller root and the propeller hub by hydraulic oil pressure, once the optimum pitch of the propeller blades is determined. |
