Abstract: A gutter system has the portions thereof formed to permit the ends of sections thereof to be nested one within another for forming the elements of the gutter. A contour suitable for such nesting has a vertical fascia panel, a generally vertical outer panel, and a generally horizontal floor panel joining lower edges of fascia panel and the outer panel. An arcuate portion joins the lower end of the fascia panel to the floor panel. A lip is provided along the upper edge of the outer panel with the lip of a first length of gutter fitting around the lip of a second length and the arcuate portion between the fascia panel and the floor of the first length fitted around the arcuate portion joining the fascia panel and floor of the second length to provide nesting. Fold over tabs may be provided along the upper edge of the fascia panel and the lip to lock the ends of the two lengths together, or lock the end of a length of gutter to a corner unit, a down spout drop unit, or an end cap unit.

Abstract: A device for extending across a gutter for separating trash from rain water running off a roof has a planar metal body secured to the roof and to the outer edge of the gutter. A plurality of elongate louvers are cut into the metal body so that they extend parallel to the gutter. The louvers are arranged in columns and are twisted to form openings between which the water will flow.

Abstract: A method for recording, at the point of sale, data arising from credit card transactions, makes use of a novel apparatus disclosed in a co-pending Application, entitled APPARATUS FOR RECORDING AND PROCESSING CREDIT TRANSACTION DATA, Ser. No. 132,050. More particularly, the method involves simultaneously recording credit transaction data on both a customer credit receipt and on a single line of data paper. The data paper is advanced after each sale, thereby producing a line by line description of each individual credit transaction. Since the data paper is capable of direct input to a computer, for conversion to separate customer statements, it reduces the amount of manual and machine handling of billing information.
