Abstract: The self cleaning rain gutter system of this invention has the quadruple advantage of being easy to install, being clog resistant, being self cleaning, and being without visible slope. Ease of installation is accomplished by modular sections made up of box, gutter and louver rack. These are simply installed level, using the fascia board as a guide as well as a support. A modular section may be installed fully assembled, with preset slope and leader funnel with cleaning water connections--or, at the option of the installer, may be mounted in a two step procedure, first the support box and then the gutter and louver rack. Clog resistance is provided by an integral top grating which interdicts most leaves and twigs as well as the occasional tennis ball. These larger items tend to provide the framework for clogs. The smooth rounded cross section of the bottom of the inner gutter also tends to resist clogging.

Abstract: The invention is a poolside descending scaffold having an apron bar which is extendable by an apron arm extender fitted into its two end pieces, which are rectangular box girders of light metal or steel. End pieces are affixed to the extender by pad bars with threaded internal pins. The pad rods carry pads which are of sufficient area to prevent rotation of the apron bar. The pads may be simple flat metal pads or may be eccentric blocks or screw pads useful in leveling the apron bar. The apron bar has a weight basket at its distal end and a hinge bracket at its poolside end. The hinge bracket holds a descending bar at a position along its length determined by a pin through one of a set of holes in the descending bar and through holes in the hinge bracket. The descending bar has ladder pins to ease the climb between poolside apron and scaffold plank, and a bumper bar on a threaded pin which can also serve to affix the plank bracket to the descending bar.
