Coal Hole Covers, Vent and Sidewalk Doors     We make sidewalk doors to lie flush with the pavement, presenting no obstructing hinges or handles to be stumbled over. Every sidewalk door is provided with our patented gutter that takes care of all leakage of water. The improved countersunk hinges and underside locks are supplied only in our various constructions.     We supply any of our construction with covers for any openings desired, to be built in as part of the pavement or roof. For vents only, the cross bars in the Paschall frame can be left in, so that even with the vent open entrance is impossible.     Our special book on sidewalk doors, vents, etc., will describe these different forms fully. Ask for Catalog No. 14-D. 3-Way Prisms for Transoms     Every architect, as well as those who are interested in the daylighting of store rooms, offices and work rooms should get our Catalog No. 14-P. This rather comprehensive booklet gives a full description of the most satisfactory ways of illuminating rooms that are dark and gloomy.     For factories, school-houses and other large surface installations, the sheet prism glass made by us gives very satisfactory results in the way or lighting dark spaces.     3-WAY Prism tiles set in the form of transoms or as canopies are shown to be the ideal form of lighting. Economical, effective, attractive and efficient, the 3-WAY prism lights are the most satisfactory method of illumination. The full benefit of the prism glass cannot be secured unless the proper and correct form of prism angle be used; and this is determined only by several conditions which are fully outlines in our book.    You are entitled to all the daylight that you can get and we will help you get your share, economically, if you will write us.
