Abstract:
An oar that uses the resistance of water to turn a paddle back and forth
as it rotates along a shaft thus creating propulsion for any watercraft.Claims:
1. An oar comprising a shaft, a paddle, and optional ball bearings
2. The oar of claim 1 includes a cylindrical shaft with a short protrusion that extends between two stoppers.
3. The shaft of claim 2 also has an unaltered length.
4. The shaft of claim 2 has an optional, unaltered length to allow for ball bearings.
5. The paddle of claim 1 has a uniquely shaped hole going completely through the length of it.
6. The ball bearings of claim 1 can be welded to the shaft of claim 1 and paddle of claim 1.
Description:
BACKGROUND
[0001] There is no other oar that pivots the paddle along a beam to create propulsion, while it's going side-to-side.
Advantages
[0002] Can be used on Navy ships. Offers improved speed and maneuverability.
REFERENCE NUMERALS
[0003] FIG. 1 Paddle--an extruded plane with a large end that contains an oddly shaped hole throughout
[0004] FIG. 1A Paddle--an extruded plane with a large end that contains an oddly shaped hole throughout
[0005] FIG. 2 Shaft--a long rod with a long notch and two cylinders
[0006] FIG. 2A Shaft--a long rod with a long notch and two cylinders
[0007] FIG. 3 Ball Bearing--a ball bearing with the inner part elongated
[0008] FIG. 4 Oscillating Oar--A two-way oar
[0009] FIG. 4B Oscillating Oar--A two-way oar
[0010] FIG. 4C Oscillating Oar--A two-way oar
BRIEF DESCRIPTION
[0011] FIG. 1 Paddle--Isometric view
[0012] FIG. 1A Paddle--Top view
[0013] FIG. 2 Shaft--End view (shows a notch using hidden lines)
[0014] FIG. 2A Shaft--Isometric view
[0015] FIG. 3 Ball Bearing--Isometric view
[0016] FIG. 4 Oar Assembly--Exploded View
[0017] FIG. 4A Oar Assembly--End View
[0018] FIG. 4B Oar Assembly--Assembled View
DETAILED DESCRIPTION
[0019] 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
[0020] 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
[0021] 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.
