| 3-Way Prisms are a form of window glass
scientifically arranged so as to gather the light from the sky and
project it into all parts of dark interiors. Briefly speaking, it
consists of carefully arranged lenticular surfaces running in a
vertical direction on the outside and at right angles to parellel
prismatic projections in the inner side. It is manufactured in
various forms to suit all existing conditions. They will increase
the light 25% to 30%.
This installation of 3-Way Prisms enables
the Pennsylvania Railroad to turn out some 300 incandescent lights. The
natural light from the sky is carried and diffused to a distance of 300 ft.
with most startling effects.
