(HlaHa Our Large Plates of prism glass are 54 inches wide and 72 inches high, or 72 inches wide and 54 inches high, or can be furnished as desired in single lights of smaller cut sizes. They are pressed, ground and polished on one side, and have the brilliancy and finish of polished plate glass. It is as much superior to the common, rolled sheet prism as polished plate is to the ordinary window glass, and the street surface of our glass being polished corre¬ sponds with other plate glass used in the building, and does not detract from its appearance, like the rolled sheets or small wired 4-inch prism squares. Architects will appreciate this. Beautiful in Appearance Imperial Prism Plate- Glass is a beautiful product. It is well annealed and tempered, and cuts with a diamond like plate glass, and has the same strength and durability. It should be used in upper sash of windows in connection with clear glass in the lower sash, and when so installed it makes an ideal window, and is a most eltective and economical way of lighting interiors at a great saving of gas or electricity. In Efficiency the large plate or light being cut to fill the entire sash of the window opening, the effect of illumination is largely increased over the old style AiX^-inch prism plates framed up with a network of wires which obstruct the light Easily Cleaned Our large polished prismatic lights are easily cleaned like ordinary glass. They do not have hundreds of corners, inside and out¬ side, to catch the dust and dirt, like the small 4x4-inch prisms put together with wires or bars in the old way. No Rust or Leaks Our prism glass being in one plate, and not framed up like the small 4-inch prisms, there is no metal work to corrode or wear out, requiring costly renewal, and there can be no leaks in the corners to cause damage from dust, snow or rain.

It makes possible a reduction of a large per¬ centage in the area of light-wells, which area can be put into valuable store space. It increases the value of rentals. It lights up dark corners. It reduces or cuts out entirely the use of artificial light in the daytime. It proves a good investment, and soon pays for itself when properly installed. Its use is founded on scientific principles. Its value is recognized as a necessary article in building construction. With our large polished plates it is easily installed and cleaned. Perusal of the following pages will show you how simple a matter it is to select and order prism glass. There is no occasion to pay extraordinary prices for so-called engineering. Prism glass is a staple product and should be sold as such. f^ Any glazier can set prism glass in ordinary sash just as readily as he can set a piece of plate. The only thing necessary is to select the right angle from the foregoing table, and in certain cases to make a slight increase in sash-weights. On every piece of glass shipped we place a tag stating plainly, which is the top and which the outside. Even if these tags should become detached, however, any¬ one can determine by referring to the preceding table just how the glass ought to be set. All prism glass, except the inverted prisms I-B and I-C, are set with the shorter angle to the top of the window. Inverted prisms are set with the shorter angle to the bottom of the window.

If no other direc¬ tions are given a light ordered 24x36 is under¬ stood to be 24 inches wide and 36 inches high, and if ordered 36x24 is understood to be 36 inches wide and 24 inches high. This is very important in ordering prism glass. To ascertain the proper prism to use in order to get the best results in any case, simply divide the height of the opposite building (above the center of the window in which the glass is to be installed) by the width of the street, alley or court. The quotient Q is equal to the height of opposite building divided by the width of the street, alley or court. When quotient Q is from 0 to .46 use our D prism ] .46 u .60 a u CC u 1 Smooth side of .60 u .74 U u c u 1 glass outside .74 u .92 U a B u .92 a 1.11 u u I-B u !

The total height from the ground to the roof of the opposite build¬ ing B is 60 feet, and the width of the street 50 feet. The height then of the opposite building B above the center of window a is 60 feet minus 10 feet or 50 feet. This divided by 50, the width of the street, gives the quotient Q, or 1.00. Since Q in this case is between .92 and 1.1.1 the proper prism to use for window a is I-B. In the same way for window b the height of ,the opposite building above the center of the window is 60 feet minus 20 feet equals 40 feet, and 40 feet divided by width of street, 50 feet, gives quotient of .80, and .80 being between .74 and .92 for window b, use B prism. For window c the height of the opposite build¬ ing above the center of the window is 60 feet minus 30 feet, which leaves 30 feet, and 30 feet divided by the width of the street, 50 feet, gives us a quotient of .60, therefore the CC prism should be used for window c. In all cases prism glass should be set as close to the outside line of the building as possible. “Canopy” or “Skylight” prism glass may be used at the discretion of the architect in places where the quotient is above 1.43.

Burnham <.t Co., Architects Pressed Prism-Plate Glass Co., Morgantown, W.Va. Gentlemen: — Replying to your inquiry of this date I beg to say your lights installed on our first and second floors have made it possible to cut out the arc lamps except on the darkest days, and we are now able to match colors at any point on the floor —to us a matter of greatest importance. The saving on our light bill has been considerable, but exact figures will not be obtainable until we have made a fur ther test. We will be glad to have you refer to us any time.

Dear Sir:— In reply to your inquiry as to how well satisfied we are with the 3,000 ft. of pressed prism-plate glass which you installed for us, I desire to state that the results are far better than were anticipated. There are certain hours during the day when we can put out practically all the arc lights on our first and second floors. I have asked our head porter regarding the cleaning of this glass, and he reports that he ex¬ periences no difficulty whatever in keeping same in first-class condition. You are at liberty to bring any prospective purchaser to our store at any time, where they can see for themselves just what the glass is-doing.

J. P. Weber, Architect Pressed Prism Plate Glass Co., 512 Monadnock Building, City. Dear Sir:— Regarding your inquiry relative to the cost of cleaning your Imperial Polished Plate Prisms and Ornamental Glass as compared with the cost of cleaning other patterns of obscure glass will say that we have installed in the annex of our build¬ ing here over 14,000 sq. ft. of Imperial Polished Prisms and Ornamental Glass, about 25% of this being Polished Prisms. It has been my experience that owing to the smooth glazed surface on one side, and the ground and polished surface on the other side of your product, makes the cleaning of same far easier than Chipped Plate Glass or any pattern of Rolled Glass, and the use of prisms in the upper sash of our building, has not required any additional janitor service than we are using in the main building, where we have polished plate in both the upper and lower sash.

Bear Sir; Replying to your inquiry as to how we like the *' Imperial Plate Ornamental Glass '* which we are putting into doors and transoms of our new bank building, I take pleasure in saying that It ie eminently satisfactory. As you are aware, our original contracts called for chipped plate glass, and when my attention was called to this new and rary brilliant glass, I oanoelled the order for the chipped plate, and am rery glad indeed that I did so, as the eff:>ci of this new glass is much better. All the tenants in our building like it very much.

This product is not ground or polished, and is made with a i-inch back besides length of prisms, and thick enough to conform to the requirements of the underwriters. On account of the large size of the units, 18x60 inches, and the smooth shape of their borders, the number of joints and the possibility of leakage is reduced to a minimum. The use of these large sized prism skylight plates also immensely reduces the cost of met 1 construction in which they are placed. The largest skylight prism plate hitherto manufactured is only 13x13 inches. Our unit plates can be cut to any smaller size. They are absolutely the best product on the market for lighting rear parts of deep stores, for roofs railway stations, sheds , etc. They can be used horizontally, but to give the best effect should be set on an angle of 30^ to 45°. If amount of order warrants expense of die the size of the units in which this glass is now made can be increased either in width or height, or both.
