Abstract

213,714. Morgan, H. R. Jan. 25, 1923. Daylight reflectors. - Light is reflected into a room by a series of reflectors b fixed or adjustably held in an inclined frame a, outside the window permitting ventilation but preventing direct horizontal vision. The frame a may be hinged on a fixed rod g and adapted to slide to and away from the window, a radius arm h being provided if desired to incline it automatically when drawn in front of the window. The frame may be hinged to a hinged supporting bracket. The reflectors b may be adjustable in the frame if desired.
