The prism panels are supported in either plain or ornamental iron frames at the top of the window, and fastened securely to the outside face of the wall. Mechanical brackets are used to secure Canopies to the wall at windows above the ground floor to provide an easy method of cleaning the prisms, and also on all windows equipped with folding shutters. FIG. 6. PRISM CANOPY IN POSITION FIG. 7. COURT OF FLAT BUILDING WITH PRISM CANOPIES OVER WINDOWS FOLDING CANOPIES.     Canopies can be made to fold back as easily as a canvas awning. The advantages of this type are many. Prisms are more easily cleaned and kept free from snow. LUXFER PRISM SKYLIGHTS.     Luxfer Prism Skylights (Fig. 8) successfully distribute the daylight throughout rooms, courts, buildings, etc., as desired. Highly satisfactory results may be obtained in every case and great savings effected in the cost of artificial lighting; in many cases sufficient to offset the cost of the prisms in one year.     Luxfer Skylight Prisms are 13 inches square and 5/8 inch thick, and are designed to set in galvanized or copper skylight frames made in the usual manner. This prism is the only skylight prism which will successfully distribute the light throughout a large room, and conforms to the requirements of the Board of Fire Underwriters, and is the only skylight prism that can be made and kept water tight without repairs.
