ABSTRACT:
An apparatus for manipulating a multiple panel screen is disclosed in my U.S. Pat. No. 3,444,919, issued May 20, 1969. The patent shows a plurality of identical panels for regulating the visibility and the amount of light and air to be admitted. Each panel has a plurality of vertical columns of apertures separated by spaced apart horizontal strips. The panels are hung from a roller-shaped head piece and they are spaced apart from each other. When the screen is in normal position the apertures in successive panels are in alignment to permit the greatest amount of visibility and light. Novel means is used for rocking the head piece about its axis for vertically shifting the panels and their apertures with respect to each other for altering the visibility and light controlled by the screen. Additional novel means is used for rotating the head piece for rolling up the panels thereon for raising the screen or for unrolling the panels when lowering the screen.
