Abstract
Abstract A shoreline erosion control device having a frame fixed to the ground along the shoreline of a body of water and in the path of the wave action on the body of water. A plurality of screened louvers are pivotally secured to the frame and are adapted to pivot to the open position on the side of the frame facing away from the body of water during movement of a wave therepast. A return of the water in the wave toward the body of water will effect a closing of the screened louver and any sand that will be contained in the returning water will be strained by the screened louvers. The slightly restrictive openings in the mesh will slow the water velocity and allow the large grains of sand and soil to fall on the landward side of the screened louvers and due to the slowing of the wave action the sand particles that pass through the screen to fall on the seaward side of the device thus creating a gentle slope to the bottom.

Claim 1
Independent Claim
213 words
A shoreline erosion control device, comprising: a frame fixed to the ground along the shoreline of a body of water and in the path of the wave action on the body of water; and a plurality of selected screened louvers releasably pivotally secured to said frame and being pivotal to the open position on the side of the frame facing away from the body of water during movement of a wave therepast, each of said plurality of screened louvers consisting of a selected mesh, the size of the openings therein being selectively controlled to strain sand particles and effect the building up of sand particles of a predetermined size, a return of the water in the wave toward the lake effecting a closing of the screened louver so that any sand that will be contained in the returning water will be strained by the screened louvers, the slightly restrictive openings in the mesh of said screen slowing the water velocity and allowing the large grains of sand and soil to fall on the landward side of the screened louvers and due to the slowing of the wave action the sand particles that pass through the screen to fall on the seaward side of the device thus creating a gentle slope to the bottom.

Claim 3
Dependent Claim
92 words
A shoreline erosion control device according to claim 1, wherein said frame includes a pair of horizontally spaced posts driven into the ground; wherein each of said plurality of screened louvers is comprised of a pair of spaced tubular end members having bearing means thereon for pivotally supporting said screened louvers; and wherein said screened louvers comprise a rectangular shaped panel having an axle secured thereto, said axle being received in said bearings to render said panel pivotal with respect to said tubular end members and a mesh secured to said frame.
Claim 4
Dependent Claim
39 words
A shoreline erosion control device according to claim 2, including a plurality of pairs of posts, each having a plurality of screened louvers thereon to define an enclosed body of water in which sand particles are to be collected.
