Oscillating Oar

Description

BACKGROUND

There is no other oar that pivots the paddle along a beam to create propulsion, while it's going side-to-side.

Advantages

Can be used on Navy ships. Offers improved speed and maneuverability.

DETAILED DESCRIPTION

FIG. 1 Oar is located around an elongated notch that is on FIG. 2 Shaft. Two FIG. 3 Ball Bearings allow the rotation to occur with minimal friction between an FIG. 1 Oar and FIG. 2 Shaft.

Operation

The FIG. 1 Oar rotates back and forth on the FIG. 2 Shaft. The FIG. 2 Shaft has a long notch that catches FIG. 1 Oar once FIG. 1 Oar reaches the end of its movement. FIG. 3 Ball Bearing allows the swivel action to occur without a grinding sound being made. Once the FIG. 2 Shaft reaches the end of its range of motion and starts to move in the other direction, FIG. 1 Oar simply rotates to the other extreme and catches on the notch of FIG. 2 Shaft. In this way, The FIG. 100 Oscillating Oar can propel a watercraft very efficiently.

CONCLUSION, RAMIFICATIONS, AND SCOPE

The FIG. 100 Oscillating Oar can propel a watercraft of any size to much faster speeds than a standard propeller alone. It can be attached to the sides of watercraft in a special way only to be raised while docking. This is not like a trireme oar. A hose can spray off the seawater to prevent any corrosion from occurring, regarding FIG. 3 Ball Bearing.
