Discriminator rain gutter system
First Claim
1. A gutter assembly adapted to be attached to a fascia board located below a building roof, said gutter assembly comprising:
- a half-cylinder including an upper flange and a lower flange, each of said flanges extending radially outward from said half-cylinder and generally defining a single plane, said flanges adapted to be attached to said fascia board;
a gutter defining a fluid receiving trough having a modified channel shape and being adapted to be mounted immediately below and adjacent to said half-cylinder on said fascia board such that fluid flowing off said building roof is directed over and around the half-cylinder and into said gutter.

Abstract
A non-clogging gutter system comprised of two components: A half cylinder with flanges whose principal axis is orientated parallel to the edge of an inclined roof and is fastened to the vertical plane of the eaves and a gutter located just below the half cylinder, also mounted on the vertical plane of the eaves, but whose outer edge is recessed compared to the half cylinder. In operation, rainwater hydraulically flows down the inclined roof and onto the half cylinder where large debris, relatively unimpeded, is discharged to the ground, while the rainwater and macroscopic particles, by virtue of their higher molecular attraction compared to mass, adhere to the half cylinder finally discharging into the gutter because of the more normal orientation of the gravity vector compared to the half cylinder'"'"'s surface. The gutter is shaped so that its cross sectional area increases exponentially from bottom-to-top so that, even in light rains, the flow velocity will be relatively high, reducing dwell-time of rainwater in the gutter and thence reducing the amount of settling of macroscopic particles such as shingle grits, seeds, and pollen.
