|Terminal, Mill and Factory Daylighting.
The benefits from the Luxfer system of
Daylighting for manufacturing plants, warehouses and railroad
terminals are tangible and figurable. Facts and figures show
it saves from twenty-five to fifty per cent in artificial light;
it permits of an increased output, and allows better working
conditions for operatives and a consequent improvement in their
The medium for daylighting is Luxfer
sheet prisms, installed in ordinary window-sash in the same
manner as plain glass. It is furnished cut to proper size
and may be installed in half or whole sash, as circumstances
Luxfer Prism Canopies.
These are placed over windows at the
rear, sides, and in the light wells of buildings (see Fig. 5),
over store fronts, and wherever the direct admission of light
is prevented by high adjoining structures.
They are composed of Luxfer 4-inch
pressed crystal glass prisms of a scientifically prescribed
angle, set in iron frames revolving upon a pivot, and set at
the correct angle to the wall. Stationary or folding frames
are furnished where desired.

the approval of Boards of Fire Underwriters without necessitating
the addition of wire screens, and is the only really water-tight
