Abstract
202,529. Crowell, E. B., (Gatliff, R.). Sept. 7, 1922. Drawings to Specification. Maps and charts.-In illuminated directories, street maps and the like of the kind in which an index is provided adjacent to a map or chart, any particular locality being illuminated by pressing a switch opposite the name in the index, the lamps are mounted on the front of the map or chart, preferably in sockets drilled or tapped in the surface.
