Abstract

327,576. Gade, F. G. April 9, 1929. Signs; name and number plates.-In a sign of the type wherein a legend is cut or scratched on the rear face D of a plate of glass adapted to be illuminated through the edge, the two faces of the cut make different angles with the face D, so that light c entering from one side will undergo total internal reflection at the faces B, thus illuminating the legend, while light d entering from the other side will be refracted through the faces c and will not reach the observer. The legend is preferably formed of a series of parallel, equidistant linear cuts at right-angles to the direction of illumination. More than one pictorial representation may be thus formed on a single sheet of glass, or may be formed on separate superimposed sheets.
