PROPELLER, SPECIELLT TILL EN BAT |
摘要 |
There is disclosed a propeller adapted for driving a vehicle, such as a boat. The propeller comprises a pair of pivotally mounted propeller blades which are adapted to assume an inactive position wherein the blades are substantially aligned with the direction of vehicle movement, and a working position wherein the blades are at an angle with respect to the direction of vehicle movement. A stop means on the propeller limits the forward pivotal movement of the propeller blades to those locations between the inactive position and a stop position wherein the propeller blades each forms an oblique angle with respect to the inactive position so the propeller blades can each assume a working position which is located on either side of a perpendicular position wherein the propeller blades are perpendicularly disposed to the direction of vehicle movement. |
