Baffle mechanism and insert unit for downspout

DETAILED DESCRIPTION I claim: 1.
A downspout baffle mechanism for downspouts of a generally rectangular cross section, said mechanism comprising a baffle member mounted on a pivot axis which traverses, at the center line, the long dimension of said rectangular cross section and is aligned with a flanged side opening in the downspout, said baffle being a plate member having offset parallel flanges keyed to said pivot axis, the lower end of said plate member being curved away from the pivot axis to enter said side opening in all positions of movement of the baffle member, edge portions of the plate member being contoured to closely engage inner downspout surfaces when angularly traversing the downspout while permitting the plate member to substantially close the side opening when a baffle member is pivoted to provide juxtapositioned alignment of the plate member with the downspout wall containing such opening, said pivot axis having a radially extended integral member externally of the downspout rotatably engaging a radially extended portion of a second external member mounted on a pivot axis below and parallel to the first pivot axis, said second external member having offset means engaging a vertically movable float, whereby upward movement of the float is translated to pivotal movement of the baffle from said downspout traversing position to that of juxtapositioned alignment with the downspout wall.
2.
A downspout baffle mechanism as defined in claim 1, wherein said baffle, flanged opening, and interengaged external members are part of a short conduit section assemblage having a cross section corresponding with conventional downspouts, and means at the ends of such conduit section facilitating interengagement with a downspout upon removal of a predetermined length of downspout.
3.
A downspout baffle mechanism as defined in claim 2, wherein said interengaging means include a reduced dimension in the lower end of said conduit section facilitating entry of said section into the cut downspout, and an inner enlargement at the upper end of said conduit section facilitating entry of the cut downspout into said conduit section
