Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
124 words
An erosion control barrier comprising: a) a plurality of extended solid members, each extended solid member of generally cylindrical cross section having one end with male projections extending therefrom and a second end with notches engaging the male projections of the next adjacent solid member, the ends of said adjacent members overlapping each other to form a log-like barrier located on the surface of the ground where erosion is to be prevented, b) a fastening means functioning to connect both overlapping ends when said erosion control barrier is arranged in interlocking series, c) erosion control soil slippage retainer means comprising inner, middle, and outer fin-like projections extending downwardly at different angles from the bottom portion of each of said solid members into the ground.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
16 words
An erosion control barrier as described in claim 1, whereas said fastening means is a spike.
Claim 4
Dependent Claim
18 words
An erosion control barrier as described in claim 1, whereas said fastening means is easily connected and disconnected.
Claim 5
Dependent Claim
28 words
An erosion control barrier as described in claim 1, whereas said retainer fin-like projections are extended in a scalloped-like configuration whereby said fin-like projections are interspersed with cleaves.
Claim 6
Dependent Claim
31 words
An erosion control barrier as described in claim 1, whereas said barrier can be configured from a group of shapes such as concave, convex, straight, wave-like, random, twisted and the like.
