Abstract: A one-piece molded body includes a horizontal arm that extends into a concave longitudinal recess at the front of the roof of a leaf repellant rain gutter, a vertical arm that contacts the back wall of the gutter and contacts the bottom wall of the trough of the gutter, and by referencing on the contacts, orients a fastener in a fastener support guide portion of the body so that the axis of the fastener extends through the slot opening formed by the longitudinal front of the roof and the longitudinal top of the front of the trough.

Abstract: A trough with superimposed shield to reject leaves and allow water to enter the trough include a bracket which supports the shield and the trough and which rests on a back wall of the integral shield and trough. The front of the shield ends in a backward facing upturned curve for engaging the bracket. The front of the trough ends in a backward facing downturned curve for engaging the bracket.

Abstract: A gutter system for mounting under a structure's roof edge, which collects water run off in preference to leaves and debris, includes a shield, back support wall, and trough, integrally connected. The shield comprises a continuous double-curved convlute curve, generated on a first and a second radius, which extends from the back wall, down short of the inside of the front wall of the trough, and inward over the trough. The system is fastened to the structure by fastening means attached to the shield front, which pass generally horizontally under the shield and through the back support wall. In a preferred embodiment, the first radius has its origin generally where the trough bottom joins the back support wall, and the second radius has its origin generally at the fastening means, with their curves joining at a location where each is tangent to a common line.
