Abstract
Abstract An apparatus for generating electricity and power from the natural movement of a body of water including wave action, tide and current having a plurality of floating barges having paddle means driven by the wave, current or tide action and mounted for free rotation about a fixed pivot means in response to changes in the tide or current flow and mounted for up and down movement corresponding to the water level.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
222 words
An apparatus for generating electricity and power from wave, current and tide action of a body of water, comprising: a pivot means having a generally vertical axis of rotation which is mounted with a platform in the body of water; a floating barge laterally spaced from the platform having means mounting the barge with the pivot means for free rotation of the barge means about the axis of the pivot means in response to changes in the direction of water flow and for vertical movement of the barge relative to the axis of the pivot means in response to changes in the water level; paddle means with the barge means for engagement by the water for converting the force of the water to rotating motion; generator means on the platform having drive means operatively connected with the paddle means for converting the rotary motion to electricity and power; the pivot means having a vertical post fixed relative to the platform and the pivot means having a splined sleeve having means mounting the splined sleeve for rotation on the post; the barge means having means mounting the barge means for free rotation and vertical movement about the splined sleeve; and the paddle means having drive means operatively connected with the splined sleeve to drive the splined sleeve upon rotation of the paddle means.
Claim 2
Independent Claim
222 words
An apparatus for generating electricity and power from wave, current and tide action of a body of water, comprising: a pivot means having a generally vertical axis of rotation which is mounted with a platform in the body of water; a floating barge laterally spaced from the platform having means mounting the barge with the pivot means for free rotation of the barge means about the axis of the pivot means in response to changes in the direction of water flow and for vertical movement of the barge relative to the axis of the pivot means in response to changes in the water level; paddle means with the barge means for engagement by the water for converting the force of the water to rotating motion; generator means on the platform having drive means operatively connected with the paddle means for converting the rotary motion to electricity and power; the pivot means having a vertical post fixed relative to the platform and the pivot means having a splined sleeve having means mounting the splined sleeve for rotation on the post; the barge means having means mounting the barge means for free rotation and vertical movement about the splined sleeve; and the paddle means having drive means operatively connected with the splined sleeve to drive the splined sleeve upon rotation of the paddle means.
Claim 3
Dependent Claim
31 words
The apparatus as set forth in claim 1, wherein: the generator means having a second drive means operatively connected with the splined sleeve to drive the generator means to produce electricity.
Claim 4
Dependent Claim
27 words
The apparatus as set forth in claim 1, wherein: the splined sleeve having vertical longitudinal splines extending from the low tide level to the high tide level.
Claim 5
Dependent Claim
36 words
The apparatus as set forth in claim 1, wherein: the generator means having a platform supporting an electric generator and spaced from the pivot means to permit rotation of the barge means about the pivot means.
Claim 6
Dependent Claim
61 words
The apparatus as set forth in claim 4, wherein: a plurality of pivot means each with barge means having paddle means which are laterally positioned from the platform at intervals about the platform; and the generator means having drive means operatively connected with the plurality of barge means for converting the rotary motion of the paddle means to electricity and power.
