Abstract
Abstract A rainwater run-off dispersion system comprising mounting means and receiving surface with a plurality of fixed baffles, spaced tangentially at the roof edge of a building in the path of rainwater falling therefrom and preferably inclined outwardly and downward away from said building, said baffles uniformly distributing and dispersing rainwater away from same building and breaking up same into a relatively fine and dispersed shower of droplets.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
181 words
A rainwater run-off dispersion system and method for disposing of rainwater run-off from a sloped or pitched roof of a building, by converting said rainwater into a non-errosive shower of droplets and distributing over an extended area of the ground, by means of a structure mounted at the roof edge, which comprises: a receiving surface, solid and impervious, elongated and of sufficient width to intercept the path of rainwater run-off flowing therefrom, a plurality of raised, intermediate baffles, which project upwards from said receiving surface, and extend continuously in the direction of elongation, to impede the flow of said rainwater run-off, a final breaker baffle which projects upward from said receiving surface, and extends continuously in the direction of elongation, at the edge of said receiving surface furthest from, but in a plane parallel to said roof edge, and from which, said rainwater run-off overflow falls in showers of droplets to the ground, a mounting means to secure said structure to the facia board of said building, so that said receiving surface is tangentially aligned and firmly positioned against roof edge.
Claim 2
Dependent Claim
181 words
A rainwater run-off dispersion system and method for disposing of rainwater run-off from a sloped or pitched roof of a building, by converting said rainwater into a non-errosive shower of droplets and distributing over an extended area of the ground, by means of a structure mounted at the roof edge, which comprises: a receiving surface, solid and impervious, elongated and of sufficient width to intercept the path of rainwater run-off flowing therefrom, a plurality of raised, intermediate baffles, which project upwards from said receiving surface, and extend continuously in the direction of elongation, to impede the flow of said rainwater run-off, a final breaker baffle which projects upward from said receiving surface, and extends continuously in the direction of elongation, at the edge of said receiving surface furthest from, but in a plane parallel to said roof edge, and from which, said rainwater run-off overflow falls in showers of droplets to the ground, a mounting means to secure said structure to the facia board of said building, so that said receiving surface is tangentially aligned and firmly positioned against roof edge.
Claim 3
Dependent Claim
69 words
The rainwater run-off dispersion system, claimed in claim 1, in which said plurality of intermediate baffles are uniformly distributed across the width of said structure, project upward from said receiving surface, and are contoured in cross-section to intercept, collect, contain and control said flowing rainwater run-off to said final breaker baffle, from which the overflow volume is dispersed outward and away from said building in a shower of droplets.
Claim 4
Dependent Claim
47 words
The rainwater run-off dispersion system claimed in claim 2 in which said intermediate baffles have extending from the elongated axis a plurality of uniformly spaced, semi-circular or "V" shaped baffle protrusions or pockets extending upward away from said receiving surface and inclined outward, away from said building.
Claim 5
Dependent Claim
25 words
The rainwater run-off dispersion system in claim 3 in which said baffle protrusions are staggered uniformly from one intermediate baffle to the next intermediate baffle.
Claim 6
Dependent Claim
46 words
The rainwater run-off dispersion system in claim 3 in which the direction of incline for all said baffle protrusions on all even numbered intermediate baffles, incline toward the roof edge and said baffle protrusions on all odd numbered intermediate baffles incline toward said final breaker baffle.
