Summary
| Description |
English: Prism tile canopies on windows throw window light up and onto the ceiling of a room.
Original caption: S. S. BEMAN, Architect. Chicago, December 9, 1897. American Luxfer Prism Co., The Rookery, Chicago. Gentlemen: The windows of the Clerical Department of the Auditor, General Counsel, Purchasing Agent, Cashier, and of mailing room of the Pullman Company, in the Pullman Building, have been equipped with your Prism lights, and the result is most gratifying. Large portions of these rooms have heretofore been continually lighted artificially while in use, but since the application of your Prism lights, artificial light has been dispensed with, and a fine natural light pervades the innermost recesses of hitherto dark places, greatly to the comfort and delight of the officials and clerks. Yours truly, S. S. BEMAN, Pullman Building. |
